Abstract
Background and Aim: Pelung cockerels (Gallus gallus gallusGallus gallus gallus [Linnaeus, 1758]) are different from other native cockerels in that they have a long and unique voice, in addition to their tall, large, and sturdy body with a relatively heavy body weight (BW). The sound quality of pelung cockerels is affected by the structure of the syrinx and their large and strong chest muscles. The performance of the chest muscles, and subsequently its voice, is influenced by the hormone testosterone. The shell of blood clams (Anadara granosa Linnaeus, 1758), a saltwater bivalve is known to contain a natural aromatase blocker (NAB) capable of blocking the aromatase enzyme from converting testosterone to estradiol. This generates consistently high levels of testosterone. This study aimed to determine the effect of blood clam shell powder (BCSP) as an NAB on the growth, pectoralis muscle performance, and testes of pelung cockerels.
Materials and Methods: The study design was a completely randomized design, with 16 pelung cockerels aged 40–56 weeks divided into four treatment groups: T0 (control); T1 (BCSP [A. granosa] 0.9 mg/kg BW); T2 (zinc sulfate [ZnSO4] 0.9 mg/kg BW); and T3 (testosterone 3 mg/day). The animals were acclimatized for 7 days and then given dietary treatments for 56 days. The measurement of the comb, wattle, and chest circumference (CC) of pelung cockerels was performed on days 0, 14, 28, 42, and 56. At the end of the treatment, the pelung cockerels were sacrificed and the data of the pectoralis muscle weight (PMW), testis weight (TW), and area of the pectoralis muscle (APM) were measured. Samples of pectoralis muscle and testes were taken and fixed in 10% neutral buffer formalin for histology. The proliferating cell nuclear antigen (PCNA) was identified by immunohistochemical staining. To measure fascicle area (FA), myofiber area (MA), and enumerate, the fascicle myofibers (NM) histology preparations were stained with hematoxylin and eosin (H and E). Testicular preparations were stained with H and E to measure the diameter of the seminiferous tubules (DST) using ImageJ software.
Results: The growth performance on day 56 showed significantly (p < 0.05) higher differences of CC in T1 compared to T2 and T0, in T1 and T3 compared to T0, and in T3 and T2 compared to T0. Pectoralis muscle results, that is, FA, NM, MA, and PCNA-positive cells, showed that cockerels on treatment T3 had significantly higher results than other treatments, T1 was significantly different from T2 and T0, and T2 was significantly different from T0. In addition, the TW and DST measurement of cockerels on treatment T3 were significantly reduced (p < 0.05) than the other treatment groups.
Conclusion: The oral administration of BCSP in the role of a NAB at a dose of 0.9 mg/kg BW for 56 days improved the growth performance and pectoralis muscle, especially the CC, FA, NM, MA, and PCNA-positive cells parameters, but did not affect the PMW, APM, and testis of pelung cockerels. The administration of testosterone at 3 mg/day for 56 days contributed to the decrease in TW and DST, as well as atrophy of the seminiferous tubules of pelung cockerels.
Keywords: growth performance, muscle, natural aromatase blocker, pelung, testis.

performance and egg quality during molting and post molting
periods. JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY 2022; 64:717-726. [PMID: 35969703 PMCID: PMC9353354 DOI: 10.5187/jast.2022.e41] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 03/08/2022] [Revised: 05/13/2022] [Accepted: 05/20/2022] [Indexed: 11/20/2022]
Abstract
The study evaluated different molt-inducing methods to achieve the main goal of
molting in commercial layers during molting and post-molting periods. A total of
400 60-week-old Lohmann Brown layers were randomly divided into five groups
(eight replicates of 10 birds for each group). Laying hens in the fasting
control group received no diet from day 1 to day 10. The second group received a
molt-inducing diet recommended by the breeding company. The third group received
a wheat bran-based diet. The fourth group received a commercial layer diet with
8,000 ppm zinc (as zinc oxide, ZnO). The fifth group received an induced molting
diet given to the second group with 8,000 ppm zinc, respectively. Egg production
in the fasting control group and groups fed a diet with ZnO were significantly
lower (p < 0.001) than those in groups fed the
molt-inducing and wheat bran-based diets without ZnO during molting. Egg laying
in the fasting control group was rapidly reduced and stopped on the 5.9th day of
molting. In both groups having molt treatment with ZnO, egg production was
similarly reduced and ceased on the 6.9th day and 7.0th day of molting,
respectively, none of them differed significantly from the control. Layers fed
molt-inducing diet or wheat bran-based diet did not reach the cessation of
laying even on the 28th d of molting period. Relative weights of the ovary and
growing oocytes of layers subjected to fasting or fed diets with ZnO were
significantly lower than those of other groups. During the first two weeks of
post molting, layers fed molt-inducing diet with ZnO showed higher egg
production than the other two groups (p < 0.01). The
eggshell strength in the group fed the commercial diet with ZnO was
significantly higher than those fed the molt-inducing diet or wheat bran-based
diets at 6 weeks of post molting (p < 0.05). These
results suggest that the non-feed withdrawal molting using ZnO is more effective
in inducing molting and increasing post-molt egg production and egg quality than
other methods using a molt-inducing diet alone or wheat bran-based diet without
ZnO.

Abstract
Two-hundred-eighty-day-old broiler chicks were divided into seven groups. The groups were designated as T1, thermoneutral zone; T2, heat stressed (HS); T3, HS + zinc (Zn) supplementation (30 mg/kg); T4, HS + Zn (60 mg/kg); T5, HS + probiotic (0.1 g/kg); T6, HS + probiotic (0.1 g/kg) + Zn (30 mg/kg); and T7, HS + Zn (60 mg/kg) + probiotic (0.1 g/kg). Significant decrease (p < 0.05) was observed in villus height (VH), VH to crypt depth ratio, and villus surface area of all intestinal segments in the T2 group when compared with the T1 group. The same parameters had significantly higher (p < 0.05) values in the jejunum and ileum of the Zn- and probiotic-supplemented groups (alone + combination) when compared with the T2 group. The birds exposed to HS showed fewer (p < 0.05) intraepithelial lymphocytes (IELs) in the jejunum and ileum than the T1 group, while their count increased in the jejunum and ileum with dietary treatments. In conclusion, Zn and probiotic positively modulated the intestinal microstructures of broilers kept under high environmental temperature.

Abstract
Hyperthermia (HT) is a significant risk factor for male infertility. Most researchers investigated the effect of localized and short-term HT on male fertility. This study aimed to assess the harmful impacts of prolonged and generalized HT on testicular histology and ultrastructure in rats. The possible protective effects of vitamin E (Vit E), Vit C, and their combination were also investigated. Thirty male adult Wister rats were used (5 groups). 1- control, 2- HT, 3- Vit C, 4- Vit E, and 5- Vit C + Vit E. Rats in groups 2-5 were subjected to HT (41°C), 1 hr daily for 2 weeks. HT-induced a significant decrease in body weight gain, food and water intake, and serum testosterone. HT showed a damaging effect on the testicular and coda epididymis tissue. HT significantly (p ≤ .05) produced oxidative stress (decreased serum catalase (145.49 ± 8.98), glutathione peroxidase (20.27 ± 4.46), superoxide dismutase (2.68 ± 0.54), and reduced glutathione (5.18 ± 0.33), and increased malondialdehyde (9.46 ± 1.55). Vit E alone and combined with Vit C, significantly protected the gonads against the deleterious effects of HT. The results recommended that prolonged HT of the whole body is harmful to male fertility. Prophylactic therapy with Vit E could help decrease the HT-induced male gonadal harm.

Abstract
This experiment aimed to investigate the effect of different levels of zinc (Zn) and a probiotic on the growth and intestinal health of broiler chickens. One hundred ninety-two-day-old broiler chicks were randomly assigned to 6 groups. The birds were supplemented with Zn (30 and 60 mg/kg) and a probiotic mixture alone or in combination with Zn. The results revealed that the broilers receiving a probiotic mixture alone or in combination with Zn (30 and 60 mg) increased (P < 0.05) final body weight, feed conversion ratio (FCR), and total goblet cell count in duodenum compared with the control group. Morphometry of the duodenum also revealed an increase (P < 0.05) in villus height (VH) and the ratio of VH and crypt depth in all the supplemented groups, whereas ileal VH increased (P < 0.05) only in Zn60 group when compared with control. Based on our results, we concluded that compared to the individual supplementation, the combined effect of Zn and probiotic mixture was superior in improving the growth performance and histomorphology of the intestine; however, the effect of two levels of Zn did not vary when combined with probiotic.

Abstract
Zinc (Zn) is an essential trace mineral in breeder hen diets and functions in diverse physiological processes, including reproduction, immunity, antioxidant ability, and epigenetic processes. In this paper, five main aspects of Zn nutrition in poultry breeder birds and hens, including semen quality, molting, egg production and egg quality, hatchability and embryonic development, and offspring performance, are reviewed. Zn deficiency in poultry breeder birds led to lower semen quality (reducing around 10% sperm motility) and egg production (lowering 3-10 g/day/bird egg mass) as well as poor offspring development and growth performance (increasing 9-10% weak chick ratio and 10% mortality of progeny). Adequate maternal or higher Zn supplementation was adopted not only to induce molting with a greater postmolt performance (rising 4-7% laying rate) but also to enhance progeny immune response and antioxidant ability via epigenetic mechanisms. Therefore, it is necessary to reevaluate the optimal Zn requirement for egg production as well as the embryonic development and offspring chick performance of breeder hens. In the last 10 years, greater attention has been focused on the effectiveness of organic Zn for improving the reproductive performance of breeders and progeny viability and immune status. In fact, organic Zn sources are not always beneficial to the above aspects. So far, it has been very important to know the exact mechanisms of greater bioavailability and the epigenetic role of organic Zn sources in the augmentation of immune status and antioxidant abilities in poultry breeder birds and offspring. Therefore, a comprehensive analysis of these key points will not only aid in maintaining the beneficial effects of Zn nutrition for breeders and their progeny under stable conditions but will also support birds under stressful conditions such as disease as well as provide a better understanding of the integrated nutrition of breeder-offspring.

Abstract
The current experiment was performed to find the potential effect of inorganic and organic forms of zinc (Zn) on growth, intestinal histomorphology, immune response, and paraoxonase (PON1) activity in broiler. In this experiment, a total of 450 broiler chickens were assigned to four experimental and control groups. The birds received organic Zn at the rate of 50 mg/kg (OZ-50) and 60 mg/kg (OZ-60) or inorganic Zn at the rate of 50 mg/kg (IZ-50) and 60 mg/kg (IZ-60) for an experimental period of 30 days. Significantly (P < 0.05) higher feed consumption, body weight, feed conversion ratio, and production efficiency factor (PEF) were recorded in OZ-50. Similarly, antibody titer against infectious bronchitis (IB) and PON1 activity was higher (P < 0.05) in OZ-50 compared with the control group. In addition, significantly (P < 0.05) higher villus dimensions and goblet cell count were recorded for the group OZ-50 compared with other treatments. It was concluded that the organic form of Zn was superior in improving the growth, histological features of intestines, humoral response, and PON1 activity in broiler.

Abstract
Vitamin E is found in high quantities in vegetable oils. Although vitamin E has multiple functions in humans and animals, its key function is protecting cells from oxidative damage. Since its discovery, several studies have demonstrated that vitamin E deficiency causes impaired fertility in humans and lab animals. However, the effects of vitamin E deficiency or of its supplementation on the fertility of farm animals, particularly on poultry, are less well studied. Therefore, a comprehensive review of the effects of dietary vitamin E on the fertility of poultry species is needed in order to understand the beneficial role of vitamin E in the maintenance of sperm and egg qualities. Based on the observations reviewed here, we found that a moderate amount of vitamin E in poultry diet significantly protects semen/sperm qualities in male birds and egg qualities in female birds via decreasing the lipid peroxidation in semen/sperms and eggs. This review provides an overall understanding of the effects of dietary vitamin E on fertility functions in poultry species.

Abstract
This research was conducted to investigate the effect of supplementation of zinc (Zn) and ascorbic acid (AA) in heat-stressed broilers. A total of 160-day-old broiler chicks of approximately the same weight and appearance were divided into four treatment groups (control, T1, T2, and T3). Control group was fed a standard diet without any supplementation. T1 was supplemented with Zn at the rate of 60 mg/kg of feed, T2 was supplemented with 300 mg/kg of feed AA, and T3 was supplemented with combination of Zn and AA. From week 3 to 5, heat stress environment was provided at the rate of 12 h at 25 °C, 3 h at 25 to 34 °C, 6 h at 34 °C, and 3 h at 34 to 25 °C daily. The results revealed that feed intake, body weight and feed conversion ratio (FCR), and weight of thymus, spleen, and bursa of Fabricius improved significantly (P < 0.05) in T3 compared to the other treatments. Antibody titer against Newcastle disease (ND), infectious bursal disease (IBD), and infectious bronchitis (IB) increased significantly (P < 0.05) in T2 and T3 groups. However, total leucocytes count, lymphocytes, and monocytes increased (P < 0.05) in all treated groups compared to control. The results indicated that the supplementation of Zn or AA alone or in combination improved the performance and immune status of broilers reared under heat stress.
