Abstract
Large/abnormal Offspring Syndrome (LOS/AOS) is a congenital overgrowth condition of cattle and sheep, characterized by macrosomia, abdominal wall defects, organomegaly, difficulty to stand and suckle at parturition. The condition was first described as an exclusive consequence of assisted reproductive technologies, such as in vitro production and somatic cell nuclear transfer (cloning). However, we recently reported the spontaneous occurrence of this syndrome in cattle. The etiology of LOS is unclear, although the syndrome is an epigenetic condition characterized by multi-locus loss-of-imprinting, global dysregulation of small and long RNAs, changes in DNA methylation, and altered chromosomal architecture. These molecular and epigenetic changes affect biological pathways implicated in organ size, cell proliferation, cell survival, resulting in the phenotypes which characterize LOS. The lack of accurate tools for the prediction and diagnosis of LOS and the prevention of dystocia resulting from fetal overgrowth is a major concern for the dairy and beef industries. Furthermore, death of the calf and/or dam during calving adds animal welfare issues and affects the net income of the industry. An early diagnosis of LOS/AOS during gestation is critical to facilitate the decision-making process on whether to allow the pregnancy to continue or not in order to prevent harm to the dam as well as to provide producers with the timely necessary information to prepare for a difficult birth. The present review summarizes the definition, traits, incidence, and molecular characteristics of LOS to provide information and serve as a guide for future investigations regarding the early identification of LOS during pregnancy in cattle.

Abstract
Buffaloes are raised by small farm holders primarily as source of draft power owing to its resistance to hot climate, disease, and stress conditions. Over the years, transformation of these animals from draft to dairy was deliberately carried out through genetic improvement program leading to the development of buffalo-based enterprises. Buffalo production is now getting more attention and interest from buffalo raisers due to its socioeconomic impact as well as its contribution to propelling the livestock industry in many developing countries. Reproduction of buffaloes, however, is confronted with huge challenge and concern as being generally less efficient to reproduce compared with cattle due to both intrinsic and extrinsic factors such as poor estrus manifestation, silent heat, marked seasonal infertility, postpartum anestrus, long calving interval, delayed puberty, inherently low number of primordial follicles in their ovaries, high incidence of atresia, and apoptosis. Assisted reproductive technologies (ARTs) are major interventions for the efficient utilization of follicle reserve in buffaloes. The present review focuses on estrus and ovulation synchronization for fixed time artificial insemination, in vitro embryo production, intracytoplasmic sperm injection, cryopreservation of oocytes and embryos, somatic cell nuclear transfer, the factors affecting utilization in various ARTs, and future perspectives in buffaloes.

Abstract
In vitro embryo production and embryo transfer (ET) in buffaloes has been developed for decades. However, most studies are focused on the donor or laboratory improvements, and there is a lack of reports regarding the recipients. Therefore, our aim was to investigate factors associated to pregnancy (P/ET), pregnancy loss (PL), and calving rates in buffalo recipients. The studied factors were season, recipient parity, the synchronization protocol, the CL diameter, asynchrony between the embryo and the recipient, the day of the recipient estrous cycle, the embryo (fresh vs. vitrified), the day of embryo development, and the embryo stage. These retrospective data, from a program of in vitro produced embryos, were analyzed by logistic regression, and the odds ratio was also estimated. Two factors were related to P/ET and the calving rate: (1) progesterone associated to estradiol plus eCG protocol for fixed time ET tended to affect positively P/ET on day 30 (41.9 vs. 36.1%, respectively; P = 0.07; AOR = 1.28) and P/ET on day 60 (37.8 vs. 36.1%, respectively; P = 0.09; AOR = 1.08) compared to the Ovsynch protocol; and (2) the CL diameter (≥14.5 mm) at transfer increased P/ET on day 30 (47.4 vs. 32.5%; P < 0.01; AOR = 1.87) and on day 60 (45.3 vs. 27.7%; P < 0.01; AOR = 2.16), and also the calving rate (37.9 vs. 21.7%; P < 0.01; AOR = 2.20). PL was greater when ET was done in the nonbreeding season compared to the breeding season (PL 30-60: 12.8 vs. 0.0%, P = 0.01; AOR > 999.99; PL 60-calving: 26.8 vs. 3.6%, P = 0.03; AOR = 9.90; and PL 30-calving: 36.2 vs. 3.6%, P = 0.01; AOR = 15.30). In conclusion, the data of our study indicated that the synchronization protocol, the CL diameter, and ET during the breeding season impacted the reproductive efficiency of buffalo recipients.

Abstract
Transvaginal follicular aspiration technique together with in vitro embryo production are the biotechnological alternatives currently available to support genetic improvement breeding programs in buffalo species. However, aspects related to animal management, lack of knowledge of the metabolic needs and biochemical peculiarities of gametes and embryos, as well as the reproductive physiology characteristics have hampered progress in the results. Despite the low availability of good quality oocytes collected after OPU in donors as a physiological characteristic of buffalo species, high rates of oocyte maturation, modest embryo cleavage, blastocyst production and pregnancy rates after transvaginal embryo transfer in recipients could be obtained in buffalo in vitro embryo production programs. The results of implementing an in vitro embryo production program in buffaloes in the northern region of Pará state, Brazil, and results published by other groups demonstrate the feasibility of implementing this biotechnology in the routine of breeding programs. Nevertheless, in order to achieve better and consistent results, it is necessary to deepen the knowledge on the peculiarities of reproductive biology in this specie. Selection of donor animals based on ovarian size and ovarian follicular reserve and on the rate of blastocyst production is presented as an effective alternative to increase the efficiency of the in vitro embryo production technique applied to the buffalo species.

Abstract
The aim of this study was to determine the most efficient vitrification protocol for the cryopreservation of day 7 in vitro produced (IVP) porcine blastocysts. The post-warm survival rate of blastocysts vitrified in control (17% dimethyl sulfoxide + 17% ethylene glycol [EG] + 0.4 mol/L sucrose) and commercial media did not differ, nor did the post-warm survival rate of blastocysts vitrified in medium containing 1,2-propandiol in place of EG. However, vitrifying embryos in EG alone decreased the cryosurvival rate (55.6% and 33.6%, respectively, p < .05). Furthermore, the post-warm survival rates of blastocysts vitrified with either trehalose or sucrose as the non-penetrating cryoprotectant did not differ. There was also no significant difference in post-warm survival of blastocysts vitrified in control (38°C) media and room temperature (22°C) media with extended equilibration times, although when blastocysts were vitrified using control media at room temperature, the post-warm survival rate increased (56.8%, 57.3%, 72.5%, respectively, p < .05). The findings show that most cryoprotectant combinations examined proved equally effective at supporting the post-warm survival of IVP porcine blastocysts. The improved post-warm survival rate of blastocysts vitrified using media held at room temperature suggests that the cryoprotectant toxicity exerted in 22°C media was reduced.

Abstract
This study was designed to compare the efficiency of the Cryotop method and that of two methods that employ a micro volume air cooling (MVAC) device by analyzing the survival and development of bovine oocytes and blastocysts vitrified using each method. In experiment I, in vitro-matured (IVM) oocytes were vitrified using an MVAC device without direct contact with liquid nitrogen (LN2; MVAC group) or directly plunged into LN2 (MVAC in LN2 group). A third group of IVM oocytes was vitrified using a Cryotop device (Cryotop group). After warming, vitrified oocytes were fertilized in vitro. There were no significant differences in cleavage and blastocyst formation rates among the three vitrified groups, with the rates ranging from 53.1% to 56.6% and 20.0% to 25.5%, respectively; however, the rates were significantly lower (P < 0.05) than those of the fresh control group (89.3% and 43.3%, respectively) and the
solution control group (87.3% and 42.0%, respectively). In experiment II, in vitro-produced (IVP) expanded blastocysts were vitrified using the MVAC, MVAC in LN2 and Cryotop methods, warmed and cultured for survival analysis and then compared with the solution control group. The rate of development of vitrified-warmed expanded blastocysts to the hatched blastocyst stage after 24 h of culture was lower in the MVAC in LN2 group than in the solution control group; however, after 48–72 h of culture, the rates did not significantly differ between the groups. These results indicate that the MVAC method without direct LN2 contact is as effective as the standard Cryotop method for vitrification of bovine IVM oocytes and IVP expanded blastocysts.

Abstract
The aim of this research was to estimate the variability between buffalo as oocyte donors. In Experiment 1, reproductive variables were retrospectively analyzed in buffalo (n=40) that underwent repeated ovum pick up (OPU), over 16 puncture sessions (PS). The follicular recruitment among individuals and the relationship between follicular population and oocyte production were evaluated. In Experiment 2, eight buffalo underwent OPU for 28 PS and the oocytes were processed separately to correlate follicular and oocyte population at the first PS to blastocyst (BL) production. In Experiment 1, the average number of total follicles (TFL), small follicles (SFL), cumulus-oocyte complexes (COC) and Grade A+B COC recorded in each 4-PS period had great repeatability (r=0.52, 0.54, 0.60 and 0.57, respectively). The average number of Grade A+B COC recovered during the subsequent 15 PS was positively correlated with the first PS number of TFL (r=0.60; P<0.001), SFL (r=0.68; P<0.001), COC (r=0.48; P<0.01) and Grade A+B COC (r=0.40; P<0.05). In Experiment 2, a large variability among animals was observed in blastocyst yields. When animals were grouped according to the BL yield, the greatest BL yield group had a greater (P<0.05) number of TFL (8.3 ± 0.9 compared with 5.6 ± 0.7) and SFL (7.3 ± 0.3 compared with 3.8 ± 0.7) at the first PS than the lesser BL yield group. The average number of BL produced over the subsequent sessions was correlated with the number of TFL (r=0.80; P<0.05) and COC (r=0.76; P<0.05) observed at the first PS. These results demonstrated a donor influence on the oocyte and BL production, suggesting a preliminary screening to select the donors with greater potential.

Abstract
The present study was conducted to examine post-thaw in vitro developmental competence of buffalo embryos cryopreserved by cytoskeletal stabilization and vitrification. In vitro produced embryos were incubated with a medium containing cytochalasin-b (cyto-b) in a CO2 incubator for 40 min for microfilament stabilization and were cryopreserved by a two-step vitrification method at 24℃ in the presence of cyto-b. Initially, the embryos were exposed to 10% ethylene glycol (EG) and 10% dimethylsulfoxide (DMSO) in a base medium for 4 min. After the initial exposure, the embryos were transferred to a 7 µl drop of 25% EG and 25% DMSO in base medium and 0.3 M sucrose for 45 sec. After warming, the embryos were cultured in vitro for 72 h. The post-thaw in vitro developmental competence of the cyto-b-treated embryos did not differ significantly from those vitrified without cyto-b treatment. The hatching rates of morulae vitrified without cyto-b treatment was significantly lower than the non-vitrified control. However, the hatching rate of cyto-b-treated vitrified morulae did not differ significantly from the non-vitrified control. This study demonstrates that freezing of buffalo embryos by cytoskeletal stabilization and vitrification is a reliable method for long-term preservation.

Abstract
The swamp buffalo holds tremendous potential in the livestock sector in Asian and Mediterranean countries. Current needs are the faster multiplication of superior genotypes and the conservation of endangered buffalo breeds. Recent advances in assisted reproductive technologies, including in vitro embryo production methodologies, offer enormous opportunities to not only improve productivity, but also to use buffaloes to produce novel products for applications to human health and nutrition. The use of molecular genomics will undoubtedly advance these technologies for their large-scale application and resolve the key problems currently associated with advanced reproductive techniques, such as animal cloning, stem cell technology and transgenesis. Preliminary success in the application of modern reproductive technologies warrants further research at the cellular and molecular levels before their commercial exploitation in buffalo breeding programmes.

Abstract
The domestic buffalo is an indispensable livestock resource to millions of smallholder farmers in developing countries, particularly in Asia. Although its reproductive biology is basically similar to that of cattle, there are important differences and unique characteristics that need to be considered in order to apply modern reproductive technologies to improve its productivity. Under most smallholder production systems, the reproductive efficiency of buffalo is compromised by factors related to climate, management, nutrition and diseases. However, when managed and fed properly, buffalo can have good fertility and provide milk, calves and draught power over a long productive life. The basic technical problems associated with artificial insemination in buffalo were largely overcome two decades ago, but the technology has not had the expected impact in some developing countries, because largely of infrastructural and logistic problems. Approaches involving the use of hormones for treating anoestrus and for synchronizing oestrus have had varying rates of success, depending on the protocols used and the incidence of underlying problems that cause infertility. Embryo technologies such as multiple ovulation embryo transfer, in vitro embryo production, cryopreservation and cloning are being intensively studied but have had far lower success rates than in cattle. Improving the productivity of buffalo requires an understanding of their potential and limitations under each farming system, development of simple intervention strategies to ameliorate deficiencies in management, nutrition and healthcare, followed by judicious application of reproductive technologies that are sustainable with the resources available to buffalo farmers.

Abstract
This study examined the effect of including one of two growth factors (100 ng/ml IGF-1 or 20 ng/ml EGF) in combination with one of two antioxidants (50 microM cysteamine or 50 microM beta-mercaptoethanol) in maturation, fertilization and subsequent development of buffalo oocytes. The oocytes were recovered by in vivo ovum pick-up technique from six Murrah buffalo heifers twice a week over a period of 16 weeks. Immediately after ovum pick-up oocytes recovered from six donors were allocated randomly to five different maturation treatments. The control treatment was the basic maturation medium (MM; TCM-199 supplemented with 10% FBS, 10 IU/ml LH, 0.5 microg/ml FSH, 1 microg/ml estradiol-17beta and 50 microg/ml gentamicin). The other four treatments consisted of the control maturation medium (MM) plus one combination of a growth factor and an antioxidant viz. IGF-1+cysteamine; IGF-1+beta-ME; EGF+cysteamine or EGF+beta-ME. The total number of oocytes assigned to each maturation treatment ranged from 31 to 66. After maturation in different maturation medium, media used for in vitro fertilization and subsequent development of embryo was same for all groups. Data were analysed using Chi-square test. The maturation rate observed for the growth factor plus antioxidant treatments was similar to that for the control (90.4%). The highest cleavage rate recorded in the IGF-1+cysteamine treatment (71.9%) which was significantly higher (P<0.05) than the IGF-1+beta-ME (45.2%) and EGF+beta-ME (46.4%) treatments, but not significantly differ from the control (63.8%) and EGF+cysteamine treatment (60.7%). The proportion of cleaved oocytes those developed to blastocyst stage was significantly higher in the IGF-1+cysteamine treatment (52.2%; P<0.05) than in the control (23.3%), the EGF+cysteamine (13.5%) or the EGF+beta-ME (7.7%) treatments, but did not differ significantly from the IGF-1+beta-ME (28.6%) treatment. Following non-surgical transfer of 15 embryos to 14 synchronized recipients, four became pregnant and only one recipient sustained the pregnancy as long as 4.5 months when spontaneous abortion occurred. It was concluded that supplementing the maturation medium with IGF-1+cysteamine improved the production of buffalo embryos significantly in vitro culture.

Abstract
Embryo transfer techniques in water buffalo were derived from those in cattle. However, the success rate is much lower in buffaloes, due to their inherent lower fertility and poor superovulatory response. The buffalo ovary has a smaller population of recruitable follicles at any given time than the ovary of the cow (89% fewer at birth). In addition, estrus detection is problematic. Progress in the field of embryo transfer in water buffalo has been slow, and is primarily due to a poor response to superovulation. The average yield of transferable embryos is less than one per superovulated donor. In vitro embryo production could considerably improve the efficacy and logistics of embryo production. The technique of Ovum Pick Up is superior to superovulation; it can yield more transferable embryos per donor on a monthly basis (2.0 versus 0.6). The feasibility of intergeneric embryo transfer between buffalo and cattle has been investigated. No pregnancy resulted after transfer of 13 buffalo embryos to synchronized Holstein heifers. Preliminary successes with nucleus transfer of Bubalus bubalis fetal and adult somatic nuclei into enucleated bovine oocytes and subsequent development to the blastocyst stage have been reported.

Abstract
The purpose of the present study was to investigate the effects of two vitrification procedures on developmental capacity and ultrastructural changes of matured swamp buffalo oocytes. In vitro-matured oocytes were vitrified by using 35 and 40% ethylene glycol as vitrification solution for solid surface vitrification (SSV) and in-straw vitrification (ISV), respectively. Survival rate of vitrified-warmed oocytes, evaluated on the basis of ooplasm homogeneity, oolemma integrity and zona pellucida intactness, as well as parthenogenetic blastocyst rates of vitrified-warmed oocytes were significantly higher with SSV (89.3 and 13.6%, respectively) than ISV (81.8 and 5.5%, respectively). However, they were still significantly lower than that of control oocytes (100 and 34.2%, respectively). For examining the ultrastructural changes, fresh, VS-exposed (ISV and SSV), and vitrified-warmed (ISV and SSV) oocytes were processed for transmission electron microscopy. In VS-exposed oocytes, reduction of microvilli abundance and damage of mitochondrial membrane were found only in the ISV group. In vitrified-warmed oocytes, however, it was clear that both methods of vitrification induced profound ultrastructural modifications to microvilli, mitochondria, oolemma and cortical granules as well as to the size and position of vesicles. Damaged mitochondria were, however, more abundant in ISV vitrified oocytes than in SSV vitrified oocytes, which correlated with the developmental data, showing the superiority of the SSV method. The present study demonstrated the feasibility of vitrification of in vitro-matured swamp buffalo oocytes.

Abstract
The present study was conducted to investigate the effect of meiotic stages during in vitro maturation (IVM) on the survival of vitrified-warmed buffalo oocytes, vitrified at different stages of IVM. Cumulus oocyte complexes obtained from slaughterhouse ovaries were randomly divided into 6 groups: control (non-vitrified, matured for 24 h at 38 +/- 1 degrees C, 5% CO2 in humidified air), and those matured for 0 h (vitrified before IVM) or 6, 12, 18 and 24 h before vitrification. Cumulus oocyte complexes were vitrified in solution consisting of 40% w/v propylene glycol and 0.25 mol/L trehalose in phosphate-buffered saline supplemented with 4% w/v bovine serum albumin. Vitrified cumulus oocyte complexes were stored at -196 degrees C (liquid nitrogen) for at least 7 days and then thawed at 37 degrees C; cryoprotectant was removed with 1 mol/L sucrose solution. Cumulus oocyte complexes in the 0, 6, 12, 18 and 24 h groups were then matured for an additional 24, 18, 12, 6 and 0 h, respectively, to complete 24 h of IVM. Among the five vitrification groups, 89-92% of cumulus oocyte complexes were recovered, after warming, of which 84-91% were morphologically normal. Overall survivability of vitrified cumulus oocyte complexes was lower (p < 0.05) than that of non-vitrified cumulus oocyte complexes (94.5%). Survival rates of cumulus oocyte complexes matured 24 h prior to vitrification (61.3%) were higher (p < 0.05) than those matured for 12 h (46.7%), 6 h (40.6%) and 0 h (37.6%). Nuclear status following 24 h IVM was assessed. A higher proportion of non-vitrified (control) oocytes (72.7%) reached metaphase II (M-II) stage in control than oocytes vitrified for 24 h (60.0%), 18 h (54.4), 12 h (42.3%), 6 h (33.3%) and 0 h (31.6%) (p < 0.05). The results suggest that length of time in maturation medium prior to vitrification influences post-thaw survivability of buffalo oocytes; longer intervals resulted in higher survival rates.

Abstract
For the purpose of ascertaining parameters to embryo transfer on some domestic animals, mouse morulae were used as a model to investigate the effect of in-straw thawing on in vitro and in vivo-development of vitrified embryos. Embryos were vitrified in 0.25 ml straws preloaded with dilution solution (0.5 M Sucrose) and thawed in the straw by mixing the vitrification solution (Ethylene glycol + Ficoll 70 + Sucrose) and the dilution solution at 25 degrees C. The embryos were randomly divided into six groups and expelled from the straws after they had been suspended in the in-straw mixture for 3 min, 5 min, 8 min, 12 min, 16 min, and 20 min, respectively, and then they were collected under a microscope for in vitro culture or direct transfer. The in vitro developmental rates of the embryos were 92.3% to 98.4% and hatching rates were 64.1% to 75.6% for the groups of 3 min to 16 min, showing no significant differences with those of nonfrozen controls (100%, 76.2%; P > 0.05). While embryos were suspended in the straw for 20 min, the developmental rate (86.6%) and hatching rate (52.4%) were significant lower than those of the control (100%, 76.2%; P < 0.01). When the 168 frozen-thawed embryos (in-straw thawing for 5 min) and 168 fresh embryos were transferred, respectively, the proportion of live fetuses in the pregnant recipients between them (58.7% vs. 54.5%) showed no significant difference (P > 0.05). The data indicate that vitrification with EFS30 and suspension in the in-straw mixture for 3 min to 16 min, when thawing, did not affect the in vitro developmental rate and hatching rate. Moreover, the in vivo developmental rate between vitrified embryos and fresh embryos did not differ significantly. It can be concluded that this method is fit for nonsurgical embryo transfer in some domestic animals with a suggestion that the operation of embryo transfer should be accomplished within 16 min.

Factors affecting cryosurvival of nuclear-transferred bovine and swamp buffalo blastocysts: effects of hatching stage, linoleic acid–albumin in IVC medium and Ficoll supplementation to vitrification solution. Theriogenology 2005; 64:1185-96.

Abstract
The objective was to determine whether the hatching stage of cattle and swamp buffalo somatic cell nuclear-transferred (SCNT) blastocysts affected cryosurvival after vitrification, and whether addition of linoleic acid-albumin (LAA) to the IVC medium and Ficoll to the vitrification solution improves cryosurvival. Fused couplets were activated with ethanol and cycloheximide-cytochalasin D (day 0), and were allowed to develop in the presence of 0.3% BSA or 0.1% LAA+0.2% BSA. Hatching blastocysts were harvested at day 7.0 (cattle) or day 6.5 (buffalo), and classified into one of three categories, according to the ratio of extruding embryonic diameter from zona to embryonic diameter inside the zona. The blastocysts were vitrified in 20% DMSO+20% ethylene glycol+0.5M sucrose, with or without 10% Ficoll in TCM199+20% FBS, using Cryotop as a cryodevice. The post-thaw survival of the blastocysts was assessed by in vitro culture for 24h. In cattle, when the LAA-supplemented IVC medium and the Ficoll-free vitrification solution were used, cryosurvival of the early-hatching blastocysts (77%) was not different from those of middle- and late-hatching blastocysts (74 and 80%, respectively). Inclusion of Ficoll in the vitrification solution did not improve the cryosurvival of SCNT blastocysts (54 to 68%). Early-hatching SCNT blastocysts produced in the absence of LAA were sensitive to the vitrification procedure (cryosurvival 56%; P<0.05 versus 80% in the late-hatching blastocysts). The full-term developmental potential of SCNT blastocysts was proven only in the non-vitrified control group. In buffalo, the mean cryosurvival of hatching SCNT blastocysts produced with LAA (89%) was not different from that of those produced without LAA (87%). In conclusion, bovine SCNT blastocysts, regardless of their hatching stage, were relatively resistant to vitrification by the ultra-rapid cooling procedure when the blastocysts were produced in the presence of LAA. Furthermore, swamp buffalo SCNT blastocysts were more tolerant of vitrification than bovine SCNT blastocysts.
