Abstract
Gray-scale ultrasonic imaging (UI) was introduced in 1980 and initially was used to examine clinically the reproductive tract of mares. By 1983 in mares and 1984 in heifers/cows, UI had become a tool for basic research. In each species, transrectal gray-scale UI has been used extensively to characterize follicle dynamics and investigate the gonadotropic control and hormonal role of the follicles. However, the use of transrectal UI has also disclosed and characterized many other aspects of reproduction in each species, including (1) endometrial echotexture as a biological indicator of circulating estradiol concentrations, (2) relative location of the genital tubercle for fetal gender diagnosis by Days 50 to 60, and (3) timing of follicle evacuation during ovulation. Discoveries in mares include (1) embryo mobility wherein the spherical conceptus (6-16 mm) travels to all parts of the uterus on Days 11 to 15, (2) how one embryo of a twin set eliminates the other without self-inflicted damage, and (3) serration of the granulosum of the preovulatory follicle opposite to the future rupture site as an indicator of imminent ovulation. Studies with color-Doppler UI have shown that vascular perfusion of the endometrium follows the equine embryo back and forth between uterine horns and follows the expansion of the bovine allantochorion throughout each horn. In heifers, blood flow in the CL increases during the ascending portion of an individual pulse of PGF2α metabolite and then decreases. These examples highlight the power of UI in reproduction research. Without UI, it is likely that these and many other findings would still be unknown.

Abstract
The transcriptome profiles were compared for buffalo embryos with normal growth and embryos with retarded growth on Day 25 after mating. Embryos with retarded growth on Day 25 after mating have a reduced likelihood of undergoing attachment to the uterine endometrium and establishing a pregnancy. Italian Mediterranean buffaloes were mated by AI and on Day 25 underwent trans-rectal ultrasonography to ascertain embryo development. Embryos with an embryonic width (EW)>2.7 mm were classed as normal embryos and embryos with an EW<2.7 mm were classed as retarded embryos. Three buffaloes with embryos of the largest EW (3.7, 3.7 and 3.9 mm) and three buffaloes with embryos of the smallest EW (1.5, 1.6 and 1.9 mm) were slaughtered on Day 27 to recover embryos for transcriptome analysis using a bovine custom designed oligo array. A total of 1,047 transcripts were differentially expressed between embryos with normal growth and embryos with retarded growth. Retarded embryos showed 773/1,047 (74%) transcripts that were down-regulated and 274/1,047 (26%) transcripts that were up-regulated relative to normal embryos; in silico analyses focused on 680/1,047 (65%) of the differentially expressed transcripts. The most altered transcripts observed in retarded embryos were associated with membrane structure and function and with metabolic and homeostasis maintenance functions. Other notable functions altered in retarded embryos were developmental processes and in particular nervous system differentiation and function. Specific biochemical pathways such as the complement cascade and coagulation were also altered in retarded embryos. It was concluded from the findings that buffalo embryos with retarded growth on Day 25 after mating show altered gene expression compared with normal embryos, and some de-regulated functions are associated with attachment to the uterine endometrium.

Abstract
Follicle-stimulating hormone has been widely used to induce superovulation in buffaloes and cows and usually triggers functional and morphologic alterations in the corpus luteum (CL). Several studies have shown that FSH is involved in regulating vascular development and that adequate angiogenesis is essential for normal luteal development. Angiogenesis is regulated by many growth factors, of which vascular endothelial growth factor (VEGF) and fibroblast growth factor 2 (FGF2) have an established central role. Therefore, we have used a combination of in vitro and in vivo studies to assess the effects of FSH on the expression of VEGF and FGF2 and their receptors in buffalo luteal cells. The in vivo model consisted of 12 buffalo cows, divided into control (n = 6) and superovulated (n = 6) groups, and CL samples were collected on day 6 after ovulation. In this model, we analyzed the gene and protein expression of FGF2 and its receptors and the protein expression of VEGFA systems with the use of real-time PCR, Western blot analysis, and immunohistochemistry. In the in vitro model, granulosa cells were collected from small follicles (diameter, 4-6 mm) of buffaloes and cultured for 4 d in serum-free medium with or without FSH (10 ng/mL). To induce in vitro luteinization, LH (250 ng/mL) and fetal bovine serum (10%) were added to the medium, and granulosa cells were maintained in culture for 4 d more. The progesterone concentration in the medium was measured at days 4, 5, and 8 after the beginning of cell culture. Cells were collected at day 8 and subjected to real-time PCR, Western blot analysis, and immunofluorescence for assessment of the expression of FGF2, VEGF, and their receptors. To address the percentage of steroidogenic and growth factor-expressing cells in the culture, flow cytometry was performed. We observed that in superovulated buffalo CL, the FGF2 system mRNA expression was decreased even as protein expression was increased and that the VEGF protein was increased (P < 0.05). In vitro experiments with granulosa cells showed an increase in the mRNA expression of VEGF and FGF2 and its receptors 1 and 2 and protein expression of VEGF, kinase insert domain receptor, FGF receptor 2, and FGF receptor 3 in cells treated with FSH (P < 0.05), in contrast to the in vivo experiments. Moreover, the progesterone production by FSH-treated cells was elevated compared with untreated cells (P < 0.05). Our findings indicate that VEGF, FGF2, and their receptors were differentially regulated by FSH in vitro and in vivo in buffalo luteal cells, which points toward a role of CL environment in modulating cellular answers to gonadotropins.

Abstract
Protein JY-1 is an oocyte-specific protein that plays an important regulatory role in the granulosa cell layer and during the early embryo development stages. It is the first specific protein of maternal origin discovered in a single-ovulating species. In this study, the exon regions of the JY-1 gene were characterized by sequencing in 20 unrelated cattle (Bos taurus indicus) and 20 unrelated buffaloes (Bubalus bubalis). Eighteen polymorphisms were detected in cattle and 10 polymorphisms in buffaloes. Some of the polymorphisms were identified in codifying regions and caused amino acid changes. The insertion of a thymine was detected in the codifying region of exon 3 of the buffalo sequence when compared to the cattle one. This insertion causes a change in the codons frameshift from this point onwards, modifying the 19 terminal amino acids of the buffalo protein and creating a premature stop codon. This finding may explain reproductive differences between cattle and buffaloes in terms of follicle recruitment, embryo development and incidence of twin pregnancies.

Abstract
Growth, weight at birth and daily weight gain (DWG) on 12 water buffalo calves, starting from 6 days of age until completion of weaning, was investigated in this study. Different feeding regimens were given to two groups of animals with regard to daily milk replacer: (1) group 1 (G1) received a double concentration in single administration; whereas (2) group 2 (G2) received the same amount of milk replacer split twice daily. Blood samples were collected from each calf on days 6, 30, 60 and 90 to evaluate acute phase proteins (haptoglobin), bactericide activity, lysozime, total protein content and biochemical parameters. No differences were observed between the two groups in terms of dry matter intake, feed efficiency and live body weight at the end of the study. Interestingly, a significantly (P < 0.05) reduced DWG was observed earlier in G1 (day 45) than in G2 (day 60). Gastrointestinal disorders were not recorded throughout the experimental period, and no significant differences were recorded between the two groups for all considered parameters. This study confirms the possibility of utilising one daily administration of milk replacer in water buffalo calf during weaning. This new approach facilitates calves management, without interfering with calves growing performances.

Abstract
Buffaloes are generally raised in Brazil without milk-recording programs, and thus without genetic evaluations of any of their traits. This study evaluated the economic impacts of three different selection strategies on buffalo populations and the evolution of genetic trends, genetic variances and inbreeding coefficients resulting from each of them. The selection strategies used were as follows: (i) random selection; (ii) phenotypic selection; and (iii) progeny testing (PT). As the numbers of herds enrolled in milk-recording programs increased, phenotypic selection and PT strategies increased both monetary benefits and genetic trends. The extra costs of implementing milk recording (MR) and PT procedures were exceeded by the income resulting from better buffalo performance. Progeny testing is known to result in beneficial genetic trends and the use of artificial insemination promoted better distributions of genetic material into herds that were not enrolled in milk-recording programs. Phenotypic selection and PT increased mean milk production--a key factor in profitability. Inbreeding levels remained stable with phenotypic selection, even as the numbers of MR herds increased. Increases in the numbers of sires that were evaluated reduced the mean inbreeding coefficient in PT. Increasing the number of herds enrolled in milk-recording programs resulted in increased numbers of sires needed for PT, but this did not increase the inbreeding coefficient. In summary, phenotypic selection and PT strategies appear to be economically viable for buffalo husbandry in south-eastern Brazil under current (2007-2008) economic conditions and should be encouraged.

Abstract
The aim was to ascertain whether relationships between corpus luteum (CL) vascularization, CL function, and pregnancy outcome in AI in buffaloes were consistent across the breeding season and transition period to the nonbreeding season in a Mediterranean environment. Stage of the estrous cycle in Italian Mediterranean buffaloes was synchronized using the Ovsynch with timed AI program and buffaloes were mated by AI in both the breeding season (N = 131) and transition period (N = 125). Detailed investigation of CL structure and function was undertaken in 39 buffaloes at each of the respective times using realtime B-mode/color-Doppler ultrasonography on Days 10 and 20 after AI. Progesterone (P4) concentrations were determined by RIA in all buffaloes. Pregnancy rate on Day 45 after AI was greater (P < 0.05) during the breeding season (58.0%) than the transitional period (45.6%) and this was primarily the result of a lower (P < 0.05) late embryonic mortality during the breeding season (7.3%) compared with the transition period (23%). Circulating concentrations of P4 on Days 10 and 20 after AI were greater (P < 0.01) during the breeding season (4.6 ± 0.3 and 3.4 ± 0.2, respectively) than during the transition period (1.6 ± 0.12 and 1.8 ± 0.2, respectively), and this was independent of reproductive status as there was no interaction between pregnancy and season. Corpus luteum time average medium velocity at Day 10 after AI was greater (P < 0.01) during the breeding season (19.3 ± 1.5) than in the transitional period (8.3 ± 0.7). There were positive correlations in pregnant buffaloes between CL time average medium velocity and P4 concentrations on Day 10 (r = 0.722; P < 0.01) and Day 20 (r = 0.446; P < 0.01) after AI. The findings were interpreted to indicate that relationships between CL vascularization, CL function, and pregnancy outcome in AI in buffaloes are consistent across the breeding season and transition period to the nonbreeding season. The distinction between the breeding season and the transition period is the relatively low proportion of buffaloes that have CL function and P4 concentrations required to establish a pregnancy during the transition period, which is manifested in a greater incidence of embryonic mortality.

Abstract
This study describes the changes in biochemical composition of follicular fluid during reproductive acyclicity in buffalo. A total of 73 pairs of ovaries collected from 26 reproductively acyclic and 47 reproductively cyclic buffaloes were used in the investigation. Ovarian follicles were classified into small (5.0-6.9 mm), medium (7.0-9.9 mm) and large (≥10.0 mm) sized categories depending upon their diameter. Follicular fluid was aspirated, processed and assayed for glucose, cholesterol, total protein, acid phosphatase and alkaline phosphatase. Glucose concentration was lesser in reproductively acyclic compared to cyclic buffaloes (19.3 ± 2.59 mg/dl compared to 32.6 ± 2.60 mg/dl; P<0.05), mainly due to difference in concentration between small sized follicles (12.4 ± 2.59 mg/dl compared to 28.0 ± 3.32 mg/dl; P<0.05). Cholesterol concentration was also lesser in reproductively acyclic compared to cyclic buffaloes (32.2 ± 2.14 mg/dl compared to 35.5 ± 2.16 mg/dl; P<0.05) and this was related to the lesser concentration found in large follicles (13.8 ± 3.45 mg/dl compared to 37.2 ± 4.10mg/dl; P<0.001). Total protein and acid phosphatase levels were not affected by either the reproductive cyclicity status or the follicular size (4.9 ± 1.07 g/dl to 6.0 ± 0.28 g/dl and 1.2 ± 0.17 U/dl to 2.5 ± 1.22 U/dl, respectively). An increased alkaline phosphatase activity was, however, observed in reproductively acyclic compared to cyclic buffaloes (27.5 ± 3.08 U/dl compared to 14.0 ± 1.09 U/dl; P<0.0001). In conclusion, results of the present study indicate an alteration in the biochemical composition of follicular fluid during reproductive acyclicity in buffalo. The findings provide further support to the notion that poor nutrition is an important factor triggering reproductive acyclicity in buffalo.

Abstract
At Italian latitudes, buffalo (Bubalus bubalis) is a seasonally polyestrous species, showing an improved reproductive efficiency when daylight decreases (autumn). The aim of the present study was to evaluate the influence of the season on buffalo oocyte recovery rate, on oocyte quality, assessed on morphological basis, and developmental competence after in vitro fertilization. For this purpose, buffalo ovaries were collected from a local abattoir and the oocytes obtained by aspirating the follicles were evaluated, classified and, if considered of good quality, devolved to the different procedures of IVEP. In general, no differences were found in terms of oocyte recovery per ovary among seasons, but interestingly, the percentage of small oocytes was higher (P<0.05) during spring and summer (0.9±0.1 and 0.9±0.2) compared to autumn and winter (0.3±0.1 and 0.2±0.1). Both cleavage and embryo rate increased during the period from October to December (71.7±3.1 and 26.5±2.1, respectively) compared to the period from April to June (58.0±2.4 and 18.8±1.6, respectively), thus reflecting the in vivo reproductive behavior. Nevertheless, it is worth emphasizing that transferrable embryos were produced in vitro, even during the unfavorable season, but with decreased efficiency. In conclusion, these results suggest to avoid the oocyte collection during spring when planning OPU trials in order to save resources and improve the benefits/costs ratio.

Abstract
The present short communication puts on record a case of bilateral, multiple follicular cysts in a water buffalo along with a detailed description of its ovarian biometry and follicular fluid composition. The ovarian weight and biometrical parameters were much higher than in normal cycling buffaloes. A total of three follicular cysts were observed, two on the right ovary and one on the left ovary, measuring 4.9, 3.0 and 2.6 cm yielding 21, 9 and 5 ml of follicular fluid, respectively. The cystic fluid was deep yellow in colour with a viscous consistency. The follicular fluid concentrations of glucose, total protein, cholesterol, acid phosphatase, calcium, phosphorus and progesterone in all the cysts were within the range reported previously in normal buffalo follicular fluid; however, the alkaline phosphatase concentration in cyst 1 and total bilirubin concentration in cysts 1 and 2 were higher than the values in normal follicular fluid. In contrast, the levels of urea nitrogen in cysts 1 and 3, and oestradiol in cyst 3 were lower than the normal values. All the three follicles had an oestradiol to progesterone ratio less than 1. The results of our study suggest that follicular cysts in buffalo are oestrogenically inactive and have an altered concentration of certain biochemical and hormonal constituents.
