Abstract
The Doce River Basin (DRB) represents a well-described watershed in terms of contamination by metals, especially after a major environmental disaster of a mining tailing dam failure. Despite the massive mortality of the ichthyofauna, very few studies addressed the risks to the health of wild fish exposed to complex mixtures of pollutants from multiple sources. The present study proposed to investigate earlier responses of fish for assessing the impacts of multiple sources of pollution, considering: different niches of fish and target organs; and the influence of seasonality, associated with their probable sources of pollution. To achieve that, fish were collected along the DRB, and biomarkers responses were assessed in target organs and correlated with the levels of inorganic and organic contaminants. As one of the most prominent responses, fishes from the Upper DRB showed the highest expression of the metallothionein and oxidative stress parameters which were related to the higher levels of metals in this region due to the proximity of mining activities. On the other hand, higher levels of DNA damage and increased AChE activity from fish sampled in the Mid and Lower DRB were more associated with organic contaminants, from other sources of pollution than mining residues. The integrated biomarker responses also revealed seasonal variations, with higher values in fishes from the dry season, and pelagic fish showing greater variation within the seasons. The multivariate analysis integrating suitable biomarkers with chemical data represented an adequate strategy for assessing the ecological risks in the DRB, allowing the identification of distinct spatio-temporal impacts from multiple sources of contaminants. The continued exposure of the ichthyofauna representing future risks reinforces the need for ecological restoration and the protection of the fauna from the Doce River.

Abstract
The study evaluated the effects on the growth performance and carcass characteristics of broiler chickens of DL-Methionine (DL-Met) and methionine hydroxy analogue (MHA) supplementation and their partial replacement with betaine (Bet). Two experiments were performed from day 1 to 21 and from day 22 to 42. Broiler chickens were assigned to six treatments, in a completely randomized design and a 2 × 2 + 2 factorial arrangement, consisting of two Met sources (DL-Met and MHA), with or without Bet, and two negative controls. The six treatments consisted of i) NC-DLM: negative control for DL-Met with 7% reduction in DL-Met; ii) NC-MHA: negative control for MHA with 7% reduction of MHA, iii) DLM100: without Bet, supplemented exclusively with DL-Met reaching 100% of requirements, iv) MHA100: without Bet supplemented exclusively with MHA reaching 100% of requirements, v) DLM93+Bet: DL-Met at 93% of recommended level plus betaine; vi) MHA93+Bet: MHA at 93% of recommended level plus betaine. Growth from day 1 to 21 was not altered by methionine source or betaine supplementation. However, the negative controls had numerically less weight gain and feed conversion ratio (FCR) . Between days and 42 there were no effects on growth. Betaine could partially replace methionine without altering the growth of broiler chickens. In addition, the partial replacement of DL-Met with betaine increased body crude protein content. However, its use increased body fat content regardless of methionine source.

Abstract
ABSTRACT The energetic values of crude glycerin (CG) were determined for broilers at different ages using the method proposed by Matterson and by polynomial regressions. Two trials were performed with broilers from 11 to 21 and from 31 to 41 days of age. The birds were distributed in a completely randomized experimental design with a reference ration (RR), without CG, and three ration tests with replacement of 5%, 10%, and 15% of RR by CG. The metabolizable energy values were calculated by the Matterson method, and the apparent metabolizable energy (AME) values were used in polynomial regression analysis. The mean values of AME, apparent corrected for nitrogen balance (AMEn), metabolizable coefficient of gross energy (CAMEB), and corrected for nitrogen balance (CAMEBn) of CG, for the phase from 11 to 21 days by the Matterson method were 10.08 MJ kg-1, 10.04 MJ kg-1, 67.06%, and 66.74%, respectively. The inclusion of CG presented an increasing linear effect for CAMEB and CAMEBn in this period. From 31 to 41 days, these values were 10.38 MJ kg-1, 10.27 MJ kg-1, 69.02%, and 62.24%, respectively. The predicted AMEn value through the polynomial regression equations was 10.49 MJ kg-1 and 10.18 MJ kg-1, respectively. According to the equations proposed by Matterson, the crude glycerin EMAn values for broilers from 11 to 21 and 31 to 41 days of age were 10.04 MJ kg-1 and 10.26 MJ kg-1, respectively. According to Adeola's method the AMEn values were 10.49 and 10.20 MJ kg-1 for each phase.

Abstract
A total of 2622 male broilers were distributed in a 2 × 5 factorial design, using 2 lipid sources (soybean oil and palm fat), 5 levels of vitamin A supplementation (0, 3,000, 6,000, 12,000, and 24,000 IU kg−1), with 10 replicates, and also 1 control diet (CD) for each lipid source used (7 replicates), each experimental unit being composed of 23 birds. During the first 21 d (how were the birds fed) and from 22 to 42 d of age, a redistribution of the treatments was carried out in a 2 × 2 × 5 factorial design: half of the repetitions of each treatment received the diet of the initial treatment, and the others received the CD with its type of lipid source. In the phase from 1 to 21 d of age, the effect of lipid source on feed intake (FI) and feed conversion ratio (FCR), and the effect of vitamin supplementation on FI and weight gain (WG) were observed, with a quadratic response for both variables. At 42 d of age, the lipid source and vitamin A level influenced the FI, whereas the WG and FCR showed interactions between period and the level of vitamin A supplementation. Neither lipid source resulted in blood parameters out of the typical pattern for birds, and the same was observed in relation to dietary vitamin A supplementation. From 1 to 21 d of age, a vitamin A supplementation of 15,585 IU kg−1 was estimated, and at 42 d, 15,527 IU kg−1 and 15,148 IU kg −1 were estimated for the periods 1 to 21 d and 1 to 42 d, respectively.

Abstract
Abstract
Background
This study aimed to identify the use of alcohol in adult men and to verify the association with socioeconomic, demographic and mental disorders.
Methods
A cross-sectional analytical study was carried out on adults aged 20 to 59 years old in the city of Piracicaba registered in the Family Health Units (FHU) in 2018. The pattern of alcohol use was investigated in the population through the application of the AUDIT (The Alcohol Use Disorders Identification Test) instrument. Through the modified socioeconomic questionnaire by Meneghim et al, socioeconomic and demographic factors were investigated. The brief investigation of the main mental disorders: major depressive episode and generalized anxiety disorder, was carried out with the Mini International Neuropsychiatric Interview (MINI). The sample was selected “post-hoc” considering the sample, with a significance level of 5% and test power above 80% (β = 0.20) (effect size = 0, 33). After contacting the FHU and selecting participants, the interviews were conducted over the phone in one step. The eligible sample had 227 participants. After descriptive analyzes, variables with p-value <0.20 in simple analyzes were studied in multiple negative binomial regression models (95% confidence intervals).
Results
There was a high prevalence of alcohol consumption, 26.9%. The AUDIT score increased with age (RM: 1.02; 95% CI: 0.99-1.03). Protestants and evangelicals had an average AUDIT score lower than other religions (RM: 1.78; 95% CI: 1.14-2.79). People with mental disorders have an average AUDIT score higher than those without disorders (RM: 2.30; 95% CI: 1.28-4.11).
Conclusions
It is concluded that alcohol in the adult male population was prevalent, increases with age, and religion has a protective effect. We highlight the importance of the USF in the development of strategies that investigate the conditions of its population, as well as the discussion and approach of interventions
Key messages
The adult male population is more vulnerable to alcohol use and its consequences. Thus, early detection and the search for associated factors is necessary to avoid possible damage to men's health. The application of the Mini International Neuropsychiatric Interview instrument, can act preventively and with early interventions in mental disorders and in association with alcohol use.

Abstract
The cryopreservation process causes oxidative stress to the sperm cell, and the addition of antioxidants to the extender for semen freezing helps sperm protection. This study assessed the effect of L-carnitine (LC) concentrations (0, 5, or 10mM LC) on two ram semen extenders (Tris-egg yolk or the commercial optiXcell IMV medium (IMV Technologies)) for semen cryopreservation. Four Santa Inês rams were used during the breeding season. After semen collection, macroscopic and microscopic evaluations were performed, and a pool of semen was formed. The semen was diluted, and the final concentration was 100×106 per 0.25-mL straw. Cryopreservation was performed with a cooling rate of 0.25°C min−1 until 5°C, and the freezing rate used was 20°C min−1 from 5 to −120°C. After the freezing-thawing process and throughout incubation (38°C in 5% CO2) in Fert-Tyrode's albumin lactate pyruvate medium, every 1h for up to 3h, several parameters were evaluated: sperm kinetics, hypo-osmotic test, plasma membrane integrity, capacitation status, and lipid peroxidation level. We did not find any protective effect of LC on plasma membrane integrity, hypo-osmotic test, and capacitation status. The sperm kinetics values throughout incubation showed that Tris extender promoted better indices of staight-line velocity, linearity, wobble, and straightness than IMV extender along incubation, regardless of the presence of LC. There were no benefits of the LC addition throughout the incubation, and 10mM was deleterious to few parameters (amplitude of lateral head displacement, linearity, and wobble) compared with the control (0mM) in the Tris extender group. The plasma membrane integrity analysis revealed no differences (P>0.05) among the groups. The average number of intact cells (hypo-osmotic) was higher in Tris extender groups supplemented with 10mM LC at 1h and 5mM LC at 2h compared to the respective extender IMV groups. Regarding capacitation status, the Tris 5mM LC group had more acrosome-reacted cells when compared with the IMV 5mM LC group at 2h. At 3h, the percentage of acrosome-reacted cells was higher in the Tris 0-mM group when compared with the IMV 0-mM group. Regardless the presence of LC, IMV had higher (P<0.05) lipoperoxidation than the Tris treatments. In conclusion, LC supplementation in semen extender had no beneficial effect on freezing-thawing ram sperm and throughout incubation for up to 3h, with no difference in each time point evaluated. Under the conditions of this study, the use of Tris extender was superior to IMV extender for ram sperm.

Abstract
Forest biomass is an essential indicator for monitoring the Earth's ecosystems and climate. It is a critical input to greenhouse gas accounting, estimation of carbon losses and forest degradation, assessment of renewable energy potential, and for developing climate change mitigation policies such as REDD+, among others. Wall-to-wall mapping of aboveground biomass (AGB) is now possible with satellite remote sensing (RS). However, RS methods require extant, up-to-date, reliable, representative and comparable in situ data for calibration and validation. Here, we present the Forest Observation System (FOS) initiative, an international cooperation to establish and maintain a global in situ forest biomass database. AGB and canopy height estimates with their associated uncertainties are derived at a 0.25 ha scale from field measurements made in permanent research plots across the world's forests. All plot estimates are geolocated and have a size that allows for direct comparison with many RS measurements. The FOS offers the potential to improve the accuracy of RS-based biomass products while developing new synergies between the RS and ground-based ecosystem research communities.

Abstract
AIM To assess the diagnostic yield and complication rate of image-guided percutaneous rib biopsy, comparing ultrasonography (US) to fluoroscopy and computed tomography (CT)-guided biopsy techniques. MATERIALS AND METHODS A retrospective review was conducted of patients who underwent image-guided percutaneous rib biopsy at a single tertiary-care academic centre between January 2007 and June 2017. The diagnostic yield and complication rates were calculated and compared between the three imaging methods. RESULTS A total of 70 consecutive, image-guided percutaneous rib biopsies were performed in 67 patients (48 in males, 22 in females, mean age of 68.2 years, age range 31-92 years). The image guidance method utilised for biopsy was US in 64.3% (45/70), CT in 18.6% (13/70), and fluoroscopy in 17.1% (12/70). The diagnostic yield for all cases combined was 97.1% (68/70) and 97.8% (44/45) for US-guided biopsies specifically. A complication of pneumothorax was encountered in 4.3% (3/70) of all cases combined and in 4.4% (2/45) of US-guided biopsies specifically. DISCUSSION US-guided percutaneous rib biopsy has a high diagnostic yield and low complication rate, comparable to fluoroscopy or CT-guided biopsy.

Abstract
RESUMO O objetivo deste trabalho foi padronizar a técnica de acesso à pelve renal por meio de sondagem ureteral guiada por cistoscopia em éguas. Foram utilizados oito animais, de raças variadas, com peso médio de 439kg. As éguas foram sedadas e mantidas em tronco de contenção para a realização da cistoscopia com endoscópio flexível. Após identificação do óstio ureteral esquerdo, uma sonda de polietileno foi introduzida em seu lume, até a pelve renal. A localização da sonda no rim foi confirmada por meio de ultrassonografia transcutânea. Foram coletados 3mL de urina, de forma asséptica, para citologia e cultura bacteriana. Todas as amostras obtiveram resultados negativos na cultura e análise do sedimento urinário. Nenhum dos animais apresentou quaisquer complicações após a sondagem. Este estudo demonstrou que a coleta de urina diretamente da pelve renal em éguas, com auxílio da cistoscopia na realização da sondagem ureteral, consiste em um procedimento viável e seguro.

Abstract
A glicerina bruta (GB) é um coproduto gerado no processo de produção do biodiesel, do qual representa 10% do produto final. A utilização da GB na alimentação de animais não-ruminantes torna-se interessante, pois apresenta um alto teor de energia bruta e, ainda, a sua utilização pode proporcionar o retorno de parte das matérias-primas empregadas na produção de energia à cadeia alimentar, dando origem a produtos de elevado valor nutritivo. O emprego da glicerina na sua forma bruta como alimento energético vem sendo estudado como uma alternativa para a redução do custo com a alimentação animal, além de proporcionar um destino ambientalmente correto a esse coproduto. Porém, os valores enérgicos e a composição da GB, encontrados na literatura, apresentam grande variação, porque no processo de produção do biodiesel podem ser utilizadas diferentes matérias primas bem como diferentes processos. Além disso, a GB pode apresentar altas concentrações de metanol e sal (sódio ou potássio), devido a utilização do metanol e hidróxido de sódio ou potássio durante o processo de produção do biodiesel. Neste contexto, é necessário o entendimento da capacidade da utilização da GB e seus possíveis efeitos adversos em frangos de corte. Perante estes factos, o objetivo desta revisão é caracterizar a GB como um alimento alternativo para frangos de corte, bem como os fatores que devem ser avaliados antes da sua utilização.

Abstract
The objective was to use noninvasive measurements to formulate equations for predicting the abdominal fat weight of laying hens in a noninvasive manner. Hens were fed with different diets; the external body measurements of birds were used as regressors. We used 288 Hy-Line Brown laying hens, distributed in a completely randomized design in a factorial arrangement, submitted for 16 wk to 2 metabolizable energy levels (2,550 and 2,800 kcal/kg) and 3 levels of crude protein in the diet (150, 160, and 170 g/kg), totaling 6 treatments, with 48 hens each. Sixteen hens per treatment of 92 wk age were utilized to evaluate body weight, bird length, tarsus and sternum, greater and lesser diameter of the tarsus, and abdominal fat weight, after slaughter. The equations were obtained by using measures evaluated with regressors through simple and multiple linear regression with the stepwise method of indirect elimination (backward), with P < 0.10 for all variables remaining in the model. The weight of abdominal fat as predicted by the equations and observed values for each bird were subjected to Pearson's correlation analysis. The equations generated by energy levels showed coefficients of determination of 0.50 and 0.74 for 2,800 and 2,550 kcal/kg of metabolizable energy, respectively, with correlation coefficients of 0.71 and 0.84, with a highly significant correlation between the calculated and observed values of abdominal fat. For protein levels of 150, 160, and 170 g/kg in the diet, it was possible to obtain coefficients of determination of 0.75, 0.57, and 0.61, with correlation coefficients of 0.86, 0.75, and 0.78, respectively. Regarding the general equation for predicting abdominal fat weight, the coefficient of determination was 0.62; the correlation coefficient was 0.79. The equations for predicting abdominal fat weight in laying hens, based on external measurements of the birds, showed positive coefficients of determination and correlation coefficients, thus allowing researchers to determine abdominal fat weight in vivo.

Abstract
The aim of this study was to evaluate the effect of dietary supplementation of vitamin K (vit K) and Ca in the diets of laying hens on bone and blood parameters and performance during the growing phase and the effects on the laying phase up to 32 weeks. The study utilized 120 Hy-Line W-36 pullets in the growing phase (13-18 weeks), 80 laying hens in the production phase (20-32 weeks), distributed in a completely randomized design in a 2 × 5 factorial arrangement, two levels of Ca (0.8 and 1.4%) and five levels of vit K supplementation (0, 2, 8, 16 and 32 mg/kg) with four experimental units. An experimental diet was fed during the growing phase, and the commercial diet was fed during the production phase and were analysed for biochemistry and bone variables at 18 and 32 weeks. In pullets, a significant interaction of levels of vit K and Ca was observed for total serum calcium (mg/dl), Seedor index, Ca in the bones (%) and medullary bone (%). Pullets at 18 weeks of age, receiving diets with 1.4% Ca, displayed a quadratic effect of vit K with better results for these variables with 17.86, 14.59, 14.48 and 16.80 mg/kg of vit K, respectively. For level 0.8% Ca no effect of vit K was observed. The treatments during the growing phase had no effect on egg production, performance and biochemistry serum until 32 weeks. Medullary bone (%), there was a significant interaction for 1.4% Ca and a quadratic effect for vit K, with greater medullary bone areas observed with 6.09 mg/kg vit K in the diet. Supplementation with vit K in a diet with 1.4% Ca during the growing phase allowed for an increase in the area of medullary bone at 18 weeks, which was maintained until 32 weeks.

Abstract
OBJECTIVE To report the signalment, presenting clinical signs, surgical complications, histologic diagnosis, postoperative complications, and outcome of dogs and cats undergoing pneumonectomy. STUDY DESIGN Retrospective case series; multicenter study. ANIMALS Client-owned dogs (n=17) and cats (n=10). METHODS Signalment, clinical signs, side affected, surgical data, preoperative diagnostic tests (including complete blood count, serum biochemistry, cytologic diagnosis, chest radiographs, and computed tomography), histologic diagnosis, surgical complications, adjunctive therapy, and date and cause of death were collected from records of dogs and cats that underwent pneumonectomy. Survival estimates and complication were assessed. RESULTS Seventeen animals had a left-sided pneumonectomy performed (12 dogs, 5 cats) and 10 animals had a right-sided pneumonectomy (5 dogs, 5 cats). Fourteen animals were diagnosed with neoplasia (52%). The overall incidence of complications for dogs and cats were 76 and 80%, respectively, with major complications in 41 and 50%, respectively. Respiratory complications (persistent pleural effusion, oxygen dependence, persistent increased respiratory rate, or coughing) were the most frequent complications. No animals died or were euthanatized intraoperative or within the first 24 hours postoperative. One dog (6%) and 2 cats (20%) died, or were euthanatized in the first 2 weeks postoperative. CONCLUSION Based on this case series, right and left pneumonectomy can be performed with low perioperative mortality in dogs and cats, with some animals experiencing prolonged survival.

Abstract
Electroporation is a method used to deliver poorly permeant chemotherapeutic drugs to tumor cells, potentiating the cytotoxic effects of drugs and overall clinical response. Despite existing evidence of the potential benefits of electroporation to enhance the antitumoral effects of drugs, there is a lack of understanding about the effects of electroporation on equine tumor cells. This study investigated the combined effects of electroporation and bleomycin, cisplatin, and carboplatin on an equine sarcoid cell line (EqS04b). The use of electroporation increases the cytotoxic effects of bleomycin, cisplatin, and carboplatin on the equine sarcoid cell line by 5-fold, 4-fold, and 3-fold, respectively. These very promising findings demonstrate proof of principle for future preclinical studies on different tumor cells to investigate the in vivo effects of electroporation in sarcoid tumors.

Abstract
Com o objetivo de avaliar a potencialidade do uso de esterco de poedeira, comparativamente à adubação convencional na produtividade da Brachiaria brizantha na Zona da Mata Rondoniense, foi desenvolvido um experimento na Fazenda Experimental da Universidade Federal de Rondônia, Campus Rolim de Moura. O delineamento experimental utilizado foi o de blocos casualizados, com três repetições. Os tratamentos constavam de adubação com seis doses de esterco de poedeira (0, 5, 10, 20, 40 e 80 t ha-1) e adubação convencional com 120 kg ha-1 de N, 100 kg ha-1 de P2O5 e 60 kg ha-1 de K2O. Foram realizados sete cortes de avaliação no período de janeiro a julho de 2014, com intervalo de 25 dias entre cada corte e a uma altura de 15 cm do solo, com uma parcela útil de 0,25 m2. As dosagens de 40 e 80 t ha-1 de EP obtiveram as maiores produções de massa fresca e seca sendo superior estatisticamente a adubação convencional, enquanto as doses de 10 e 20 t ha-1 de EP não diferiram do tratamento convencional. Já a testemunha e a dose de 5 t ha-1 de EP foram inferiores ao tratamento com adubação convencional. A produção de matéria seca da Brachiaria brizantha respondeu linearmente ao incremento de adubação orgânica, a maior produção acumulada durante as sete coletas foi estimada em 24720 kg ha-1 MS na dose de 80 t ha-1 de EP. Desta forma conclui-se que a adubação da Brachiaria brizantha com esterco de poedeira se mostrou eficiente comparativamente à adubação convencional quando utilizado dosagem igual ou superior a 10 t ha-1, nas condições edafoclímaticas da zona da mata rondoniense.

Abstract
Com o objetivo de determinar a exigência de lisina digestível para poedeiras semipesadas no período de 50 a 66 semanas de idade, foi realizado experimento utilizando-se 150 poedeiras Shaver Brown, distribuídas em delineamento inteiramente ao acaso, com cinco tratamentos (níveis de lisina digestível: 0,79; 0,82; 0,85; 0,88 e 0,91%), seis repetições e cinco aves por unidade experimental. Foram avaliados a produção de ovos, peso médio e a massa de ovos, consumo de ração e de lisina, conversão alimentar por massa e por dúzia de ovos, gravidade específica, unidade Haugh, o índice de gema e albúmen, porcentagem de albúmen, gema e casca. O consumo de ração, a conversão alimentar por massa e dúzia de ovos, a produção, o peso e a massa de ovos não foram influenciados (P>0,05) pelos níveis de lisina digestível. Houve aumento linear no consumo de lisina (P<0,01) com o incremento dos níveis desse aminoácido nas rações. As porcentagens de albúmen, gema e casca não foram influenciadas (P>0,05) pelos níveis de lisina digestível estudados. Os níveis de lisina influenciaram de forma quadrática (P>0,05) a unidade Haugh e o índice de albúmen, sendo estimados os níveis de 0,884 e 0,868% de lisina digestível, respectivamente. Para o índice de gema, a associação do modelo quadrático ao Linear Response Plateau (LRP) estimou o nível de 0,903% de lisina digestível. Quando o objetivo é maximizar a qualidade interna dos ovos, recomenda-se o nível dietético de 0,884%, 0,868% e 0,903% de lisina digestível para unidade Haugh, índice de albúmen e índice de gema, respectivamente.

Abstract
We compared two electroretinography (ERG) electrodes in dogs using ERG standards
of the International Society for Clinical Electrophysiology of Vision (ISCEV).
Ten healthy Yorkshire terrier dogs (mean age, 2.80 ± 1.42 years; 6 females)
weighing 5.20 ± 1.56 kg were evaluated using an ERG system for veterinary use.
Dark- and light-adapted ERG responses were recorded using an ERG-Jet electrode
and a fiber electrode prototype. The examinations were performed during 2
visits, 3 weeks apart. Both electrodes (ERG-Jet or fiber prototype) were used on
each animal and the first eye to be recorded (OD × OS) was selected randomly.
Three weeks later the examination was repeated on the same animal switching the
type of electrode to be used that day and the first eye to be examined. The
magnitude and waveform quality obtained with the two electrode types were
similar for all ERG responses. ERG amplitudes and implicit times obtained from
dogs using the fiber electrode prototype were comparable to those obtained with
the ERG-Jet electrode for rod, maximal rod-cone summed, cone, and 30-Hz flicker
responses. The fiber electrode prototype is a low-cost device, available as an
alternative instrument for clinical veterinary ERG recording for retinal
function assessment.

Abstract
Determinaram-se as exigências nutricionais de metionina+cistina digestível para poedeiras de linhagem comercial no segundo ciclo de produção de 75 a 91 semanas de idade, utilizando-se 150 aves semipesadas em delineamento inteiramente ao acaso. Estas foram distribuídas em cinco tratamentos, seis repetições e cinco aves por unidade experimental, alimentadas com uma dieta basal contendo 2.859kcal/kg de energia metabolizável e 16,30% de proteína bruta, suplementada com 0,132; 0,173; 0,215; 0,256 e 0,298% de DL-metionina (98%), de forma a proporcionar 0,588; 0,628; 0,669; 0,709 e 0,750% de metionina+cistina digestível na dieta. A inclusão de metionina+cistina obedeceu, respectivamente, às proporções de 67, 72, 77, 81 e 86% com a lisina fixada em 0,872%. Avaliaram-se os consumos de ração e de metionina+cistina, a conversão alimentar por dúzia e por massa de ovos, a taxa de postura, o peso e a massa de ovos, a porcentagem dos componentes dos ovos e a qualidade interna dos ovos e o ganho de peso. A inclusão de metionina+cistina digestível nas quantidades indicadas não exerceu efeito (P>0,05) sobre as características de produção e qualidade interna e externa dos ovos. A exigência estimada foi de 0,588% de metionina+cistina digestível, correspondendo ao consumo de 654,73mg/ave/dia.

Abstract
Little is known about the role of activin B during folliculogenesis. This study investigated the expression levels of activin/inhibin subunits (βA, βB, and α), steroid enzyme, and gonadotrophin receptors in theca (TC) and granulosa cells (GC) by QPCR and activin A and B and inhibin A protein levels in follicular fluid (FF) of developing sheep follicles during estrus and anestrus. The effect of activin B on androgen production from primary TC cultures in vitro was also assessed. During folliculogenesis, in anestrus and estrus, FF activin B concentrations and thecal and GC activin βB mRNA levels decreased as follicle diameter increased from 1–3 to >6 mm regardless of estrogenic status. Estrogenic preovulatory follicles had reduced concentrations of FF activins B and A, and TC and GCs expressed higher levels of activin βA mRNA at 3–4 mm, and TCs more inhibin α mRNA at >4 mm stages of development compared with nonestrogenic follicles. Activin B decreased androstenedione production from primary TCs in vitro, an effect blocked by inhibin A. Thus, sheep follicles 1–3 mm in diameter contained high FF levels of activin B, which decreased as the follicle size increased, and, like activin A, suppressed thecal androgen production in vitro, an effect blocked by inhibin. Furthermore, the theca of large estrogenic follicles expressed high levels of inhibin α and activin βA mRNA suggesting local thecal derived inhibin A production. This would inhibit the negative effects of thecal activins B and A ensuring maximum androgen production for enhanced estradiol production by the preovulatory follicle(s).
