The liver was located in the cranial part of the abdomen, immediately behind the diaphragm, entirely to the righty of the median plane, situated in an oblique downwards and forwards. The liver was consisted of two surfaces and four borders. The parietal surface was irregularly convex having falciform and coronary ligaments, which were attached to the diaphragm. The visceral surface was irregularly concave, which consisted an upper and large omasal impression, lower and narrow reticular impression, and abomasal impression was present in the right ventral area. The lesser omentum was extended from the esophageal notch to the portal fissure. The dorsal border was short and thick having deep renal impression on caudal lobe. Ventral border was short, thin and convex. The lateral border was thin and median border was thick to which esophageal notch was present.

A study was carried out to 24 buffalos, comprising 18 buffaloes having Cervico-Vaginal Prolapse and 6 normal pregnant buffaloes (above 7 months) on clinical cases brought to the Department of Veterinary Gynaecology and Obstetrics, College of Veterinary Science and Animal Husbandry, Mhow, College dairy farm and Villages in and around Mhow to compare haemato-biochemical profile in normal and Cervico vaginal prolapsed buffaloes. Blood samples were collected initially before treatment (Day 0) and after treatment on 7th day. Haemato-biochemical parameters (haemoglobin, total leukocyte count, differential leukocyte count, serum calcium, and serum phosphorus, Serum magnesium (Mg)) were estimated and compared between control and treatment group animals. The mean values of serum calcium and inorganic phosphorus were significantly (P LT 0.01) lower in cervico vaginal affected buffaloes on day of prolapse (Day 0) which restored to nearly normal on the 7th day after treatment, though statistically significant variation was not observed.

Successful pregnancy is the outcome of a well coordinated embryo- maternal communication events. Few evidences suggest the role of cytokines signaling pathways as mediators of these communications for establishment of pregnancy. In order to investigate the role of cytokines CCL8 and CXCL10 in embryonic implantation during pregnancy, the present study aimed to develop quantitative real time PCR method based on SYBR Green dye chemistry. Primers were designed for the amplification of CCL8, CXCL10 and GAPDH (endogenous control) genes specific to bovines using Primer 3 software. The amplification products for CCL8, CXCL10 and GAPDH (endogenous control) genes yielded fragments of 388, 151 and 81 bp respectively. Purified PCR Products were used for the generation of standard curve for all the three genes. Six scalars tenfold serial dilutions of every PCR product were performed for amplification of genes by optimized protocol. Each sample was run in triplicate along with a no template control for every assay. Each run was completed with a melting curve analysis to confirm the specificity of amplification and lack of primers dimers. The standards generated linear relationships with regression coefficients: r sup(2)=0.996, 0.993 and 0.992 for CCL8, CXCL10 and GAPDH genes respectively. The method posed to be reliable approach for estimating the relative expression of cytokines CCL8 and CXCL10 in peripheral blood leucocytes in buffaloes.

The present study was undertaken to identify the difference in sperm kinematics in Murrah buffalo bulls in different seasons. Eight Murrah buffalo bulls maintained at Artificial Breeding Research Centre, ICAR-NDRI Karnal. Frozen semen samples of the bulls were obtained and sperm kinematic parameters were measured by computer-assisted sperm analyzer. The sperm kinematic parameters included curvilinear velocity (VCL), linear velocity (VSL), average path velocity (VAP), distance of average path (DAP), distance straight line (DSL), straightness coefficient (STR), linearity (LIN), amplitude of lateral head displacement (ALH), and beat cross frequency (BCF). Morphological abnormality of sperm includes bent tail (BT), coiled tail (CT), distal droplets (DD) and distal mid-piece reflex (DMR). Analysis revealed that the proportion of BT was significantly (P LT 0.05) lower in winter and autumn season as compared to summer and rainy season. Percent of total motile and progressive motile sperm was significantly (P LT 0.05) higher in winter season as compared to summer and rainy season. The VAP, VSL and VCL of sperm motion were significantly (P LT 0.05) higher in winter and autumn season as compared to the summer season. The DAP and STR were significantly (P LT 0.05) higher in winter and autumn season as compared to summer and rainy season. DSL and LIN were significantly (P LT 0.05) lower in summer and rainy season followed by autumn and winter season. Post-thaw motility and motion parameter varied significantly between seasons, and higher sperm motility was maintained in semen cryopreserved in winter followed by autumn, rainy and summer season.

The study was carried out to understand the effect of various concentrations of cholesterol loaded cyclodextrin (CLC) on cryosurvivability of buffalo spermatozoa. Twenty four ejaculates with mass motility GT= 3+ from 4 bulls (6 from each bull) were collected as per standard procedure. Each ejaculate was split into four groups viz., Group I (control: extended with Tris-egg yolk-glycerol extender upto 80*106 sperm/ml), Group II (treated with CLC 1 mg/ml), Group III (treated with CLC 2 mg/ml) and Group IV (treated with CLC 3 mg/ml). Semen samples of Group II, III or IV were incubated with CLC at 37 deg C for 15 minutes for the entry of cholesterol into sperms and finally diluted upto 80*106 sperm/ml. The results revealed that post-dilution and after freezing at 0.7 and 30 days of cryopreservation motility, live and dead, acrosomal integrity and hypo-osmotic swelling test were significantly (P LT 0.05) higher in Group III as compared to all other groups. However, significantly (P LT 0.05) higher percentage of abnormal sperm was observed in control group as compared to other groups. Therefore, addition of CLC 2 mg/ml in extender during buffalo semen cryopreservation has beneficial role in improvement of semen quality.

Information needs in buffalo production system to develop mobile apps as an extension service delivery tool were assessed and prioritized in seven distinct segments. Data were collected personally from 100 buffalo owners from Haryana and Rajasthan and mean weighted average scores were calculated and ranked. Age at puberty and maturity and identification of heat symptoms and heat detection were the two top areas under broad area of reproduction wherein majority of farmers expressed their desire to include as content in mobile app. Information on infertility and prolapse of uterus were main reproductive problems and needed information under broad area of reproductive problems. Information on characteristics of good dairy animals followed by best buffaloes suited for local conditions along with production potential were areas identified under breeding head. Respondents needed information on use of mineral mixture and computation of ration and feeding schedule as per age and stage of animal under buffalo feeding information on mastitis and control of foot and mouth disease under the disease control and control of external parasites and vaccination schedule under health management were the subareas under the head. Farmers expressed need to have information on farmers training and warning systems about diseases and weather forecasts under the broad areas of marketing and training apart from various other areas in each major segment include as content while developing the mobile app on buffalo production system.

Lactation curve and persistency of the lactation are the important parameters to study the sustainability of the lactation. The present study is based on daily milk production records for 298 lactations (maximum four lactations per animal) from 130 buffaloes belonging to 15 sires. Statistical Packages for Social Sciences (SPSS) programme was used to prepare the lactation curve. Two most widely applied functions to study the lactation curve in Indian buffaloes i.e. gamma and inverse polynomial functions, were fitted to the daily milk yield records of the animals under study. Persistency was studied by carrying out simple analysis through Microsoft Excel 2000 on the weekly milk yield records of the animals. Gamma function was found to be more effective with higher R sup(2) value for all the four lactations to prepare the lactation curve as compared to inverse polynomial function. The value of persistency was found to be ranging from 97.94 percent to 98.56 percent for the fourth lactation to the first lactation, respectively. So it was concluded that gamma function can be effectively used to establish lactation curve and predict milk yield of animals on any day of lactation and Surti buffaloes as fairly persistent in milk production throughout the lactations.

The present study was conducted in buffaloes to determine the occurrence of subclinical mastitis and its diagnosis in relation to milk SCC and biochemical composition. The results showed that taking quarter foremilk (QFM) somatic cell count (SCC) threshold limit of LT 200*10**(3) cell for defining healthy quarters, 16.48 percent of buffaloes and 5.79 percent of quarters were positive for specific subclinical mastitis. In total, 57/363 (15.70 percent)of quarters were bacteriological positive with 21 (5.79 percent) representing specific and 36 (9.92 percent) latent infections. The major pathogen isolated were 28 (49 percent) coagulase-negative staphylococci followed by 16 (28 percent) S. aureus, 09 (16 percent) Streptococcus and 4(7 percent) Corynebacterium spp. The average QFM SCC was found as 52.50*10**(3) cells /ml for the quarter with no bacteria, and 356.51*10**(3) cell /ml for the quarters infected with one or the other bacteria (p LT 0.05). The milk electrical conductivity (EC), Fat and Lactoseshowed significant alterations with the quarter infection, the EC and Fat increased while Lactose decreased in infected quarters (p LT 0.05). The California mastitis test CMT) at cut off score of GT 0.5 for diseased quarters showed 68.75 percent sensitivity with 99.09 percent specificity. The EC with 87.50 percent sensitivity and 74.02 percent specificity and Lactose with 84.37 percent sensitivity and 66.16 percent specificity also showed significant (p LT 0.01) discrimination ability to differentiate healthy and mastitis quarters in buffaloes. The milk pH was not found to be a good parameter to identify diseased quarters.

A one way anova experiment was conducted to evaluate the meat production and physicochemical properties (pH, Color, Drip loss, Cook loss, TC, TG, Cholesterol, LDL, HDL and Iron content) of cattle and buffalo meat and blood. Five buffaloes and five cattle of similar age were considered as two groups and kept under a single plane of nutrition. No significant difference was observed between the groups in case of BCS, pH, drip loss and cooking loss of fresh or chilled meat. Buffalo meat reflected (L *) low lights (P LT 0.05) and showed significant (P LT 0.01) deep red - greenness (a *) contrast than cattle meat. Iron content of meat was found (P LT 0.05) higher in buffalo meat. In chemical composition, only ash and OM content differed significantly (P LT 0.05) between the species. IM fat and TC of buffalo meat was found significantly low (P LT 0.001) than cattle. Significant difference of TG and HDL (P GT 0.05) indicated the better quality of buffalo meat. But, LDL of meat and lipid profile of blood found non - significant. Finally we observed that, buffalo meat is better than cattle meat in context of nutritive value or physiochemical properties.

The present study was designed to correlate the milk pH, somatic cell count (SCC), lactate dehydrogenase (LDH) and alkaline phosphatase (ALP) activities in buffalo milk with the udder health status. A total of 60 (Sixty) buffaloes were randomly selected irrespective of their age, breed, feeding practice, stage and season of lactation from the herd belonging to Purnadhadi buffalo unit, PGIVAS, Teaching Veterinary Clinical complex, PGIVAS, Veterinary Polyclinic, Akola and also buffaloes of farmers in and around Akola. After thorough clinical examination of each udder, about 30 ml of milk was collected in sterilized, clean, dry plastic bottles and after careful screening by CMT, categorized in normal, sub- clinical (1+), sub- clinical (2+), sub- clinical (3+) and clinical group containing 12 animals in each group. The pH was measured using a digital pH meter (E.I. Model 101E) and SCC was calculated in freshly collected milk. LDH and ALP activities were measured by spectrophotometric method. The milk pH, SCC, LDH and ALP activities were found proportional to the severity of the udder infection as detected by the CMT reactions.
