Fascioliasis causes huge economic losses in livestock industry by reducing the growth, fertility rate, meat and milk yield. In the present study, somatic antigens isolated from Fasciola gigantica were assessed for the early detection of infection by developing antibody detection enzyme immunoassay. The somatic antigens extracted from adult F. gigantica worms was separated on SDS-PAGE and immunogenicity was determined by Western blot (WB). The results showed polypeptides bands between 15 to 95 kDa, and most prominent bands were 15, 28, 36, 38, 55, 72 and 95 kDa polypeptides. The WB revealed a single polypeptide of size between 36 to 55 kDa as antigenic. The sensitivity and specificity of ELISA test established for 36 to 55 kDa somatic antigens was 95.45 percent (95 percent CI: 77.16 percent to 99.88 percent) and 87.1 percent (95 percent CI: 70.17 percent to 96.37 percent), respectively. Kappa value revealed that the strength of agreement is considered to be very 'good'. In house established ELISA was implemented in the field and 12.1 percent (31/256) large ruminants were found positive, while 4.68 percent (12/256) with postmortem examination. The fasciolosis did not show significant (P GT 0.05) association with host type, breed and age groups, while significant (P LT 0.01) association with host sexes. The result confirmed that in-house established ELISA test had good value for serodiagnosis of fasciolosis in cattle and buffaloes for large scale epidemiological studies.

The study aimed to analyze the adoption of 22 technologies on dairy buffalo production in selected sites in the Philippines. A total of 666 farmer-informants who were previously exposed to training and other extension support services on dairy buffalo production were interviewed using semi-structured questionnaire. Dichotomous (yes or no) frequency and percentage responses along five stages, i.e., 'awareness', 'interest', 'evaluation', 'trial', and 'adoption' were transformed to sigma (Z) scores for adoption. Frequency responses for 'number of years of adoption' were likewise transformed to sigma scores. The two sigma scores were added to get the total adoption scores for each technology. The total or combined adoption scores (dependent variable) for all technologies were then tested for linear correlation and multiple regression with selected socio-economic traits, farm characteristics, and other independent variables. Most of the farmer-informants had at least 75 percent adoption rate in animal health care, improved forage feeding, estrus detection, and feeding of calves with colostrum. Multiple regression analysis indicates that attribution scores, years of experience in dairying, technical assistance, animal inventory, distance of the farm from a buffalo R and D institution, access to information materials and income from dairying positively and significantly influenced adoption scores. To increase adoption, improving the attribution by farmers to technologies as regards their relative advantage, compatibility with existing farm operations, trialability, and simplicity should be given priority consideration in designing and implementing extension delivery systems since it is the most powerful predictor variable to adoption.

Systematic studies on expression and characterization of toll like receptors (TLRs) in buffalo and cattle will help to understand the innate immune response specific to each species of animals. TLR4 gene is one of the most studied innate immune receptors which is mainly triggered by lipopolysaccharide. Therefore, the present study was carried out to investigate the mRNA expression and sequence analysis of TLR4 in buffalo in comparison to that of cattle. In vitro expression of TLR4 was assessed by challenging the Peripheral Blood Mononuclear Cells (PBMC) with bacterial LPS which showed significant increase of TLR4 gene expression (P LT= 0.01) in buffaloes when compared to cattle. Further the comparison of mRNA sequence of TLR4 of buffalo and cattle revealed 96 percent similarity with the cattle sequence. The primary structure of protein showed the highest percent of leucine amino acid for both the species of animals. At the same time, the number of Leucine Rich repeats (LRR) of buffalo is varied from those present in cattle TLR4. Alpha helix is the prominent secondary structure, however, there were few amino acid variations between buffalo and cattle in certain regions of TLR4 which altered the three dimensional conformation of TLR4 proteins, this in-turn possibly can influence the binding affinity and interaction with pathogens which may influence the difference in immune response in buffalo when compared to that of cattle.

The present study is conducted to evaluate the efficacy of certain immunomodulators on recovery and conception rate in post partum endometritic buffaloes. Total 50 buffaloes were selected for the study and randomly divided into five groups. The buffaloes of Group 1 were given with a single dose of 100 micro g E. coli lipopolysaccharide as intrauterine, Group 2 buffaloes were treated with a single dose of 2 mg Lysozyme, Group 3 was treated with 4 g of Cephalexin for three consecutive days. While, Group 4 buffaloes were treated with a single dose of 2 mg Lysozyme + 4 g of Cephalexin and Group 5 was treated with 30 ml of normal saline and was kept as control. All therapeutics were infused into the uterus after dissolving in sterile water. The efficacy of treatment was assessed by declines in bacterial load and PMNL cell count after treatment. The overall conception rate was 88.88, 71.42, 66.66, 75.00 and 33.33 percent in Group 1, 2, 3, 4 and Group 5, respectively.

This study was conducted to assess the therapeutic efficiency of antioxidant in subclinical mastitis. Therapeutic trials were conducted in twelve buffaloes affected with subclinical mastitis and were randomly divided into two groups. The buffaloes of Group 1 were treated with intramuscular injection of Inj. Mofoi 5 mg/kg body weight, while Group 2 buffaloes were treated with intramuscular administration of Inj. Mofoi 5 mg/kg body weight along with antioxidant powder orally. The therapeutic efficacy was assessed based on bacteriological cure and the pre and post therapeutic values of somatic cell count, electrical resistance, pH and milk yield. The use of antioxidant along with Moxifloxacin was found to be superior than antibiotic alone by improving udder's natural defence mechanism, early restoration of milk yield and quick recovery.

Present experiment was conducted on sixty Murrah buffalo divided into three groups: lactating, involution stage/dry and pregnant stage (non-lactating early pregnant stage, non-lactating mid pregnant stage and non-lactating late pregnant stage). Most of the alveoli were spherical to oval elongated in shape. In lactating stage, only small and medium sized alveoli were present. In involuting stage due to degeneration and inactiveness only small alveoli were recorded. In non-lactating late pregnant stage most of the alveoli were large sized. A highly significant statistical difference was noted among different stages of lactation in the diameter of alveoli. The active alveoli were lined by cuboidal epithelium to low cuboidal epithelium, while resting alveoli were lined by squamous epithelium with dark nuclei. The number of resting alveoli were found increased with the advancement of lactation. Up to two months of involution most of the alveoli were degenerative. A highly significant statistical difference was noted in the height of alveolar epithelium in different stages of lactation.

Liver infections due to amphistomes in buffaloes cause significant economic losses in livestock sector. The present study investigated the classical morphological features of adult amphistomes combined with histopathology and molecular identity in slaughtered buffaloes from Khyber Pakhtunkhwa, Pakistan. Adult amphistome were collected and morphologically characterized as Gigantocotyle explanatum. Morphometric measurement (n=50) were obtained with 12.05+-1.68 mm in length and 5.77+-0.81 mm in width, and the values of sagittal section was 6.35+-1.03 * 2.98+-0.50 mm in size. Severe bile duct pathology was observed with fibrosis of the duct wall with an irregular epithelial border, hyperplasia and inflammatory response with numerous neutrophils and eosinophils. The molecular identity of G. explanatum within Paramphistomidae was confirmed by ITS-2 rDNA sequences phylogenetic analysis based on maximum likelihood method. The genetic data based on ITS-2 secondary structure of G. explanatum consisted of four helix, Helix I, II and IV were conserved as compared with other closely related reference taxa of family Paramphistomidae and Gastrothylacidae. Helix III expressed some variations. The study concluded that rDNA ITS-2 and secondary structure information provides a guide for other researchers to determine the molecular taxonomic position of Paramphistomidae trematodes, data will support future clinical studies and control measures to reduce the amphistomiasis in buffaloes.

The buffalo rearing is adopting faster rate in arid region of Rajasthan due to its multifaceted utility for both milk and meat. Despite of better management practice are adopted for buffaloes, they also depend upon grazing and poor quality of fodder to meet out their total dry matter intake. The concept of balanced feed with respect to mineral and vitamins are not aware by farmer's community. Thus, the alternative low cost balanced feed was adopted in buffaloes under field condition to augment the milk production with optimum reproductive efficiency. MNFB was developed at feed technology unit of CAZRI, as solidified block of wheat bran, guar meal, dolomite, -minerals and vitamins mixture powder, salt, molasses and urea solution. The study evaluated feeding effect of multi-nutrient feed block on milk production and reproduction performances of lactating buffaloes. The Buffaloes under treatment were divided randomly into two groups and assigned to two dietary treatments under village condition. After calving, all the buffaloes in treatment group were dewormed with albendazole 3 gms and feeding of MNFB 2 blocks (2 kgs each)/week for 3 months during March to May. The control group received diet containing bajara (Pearl millet) kuti, dry grasses, crushed cotton and til (sesame) cake. Milk production, peak milk yield were increased highly significant. Fat percentage was significantly increased. All Observations were monitored as per format. In reproductive performances were like sign of oestrus, conception and post partum reproductive complication 90 percent, 86.6 percent and 0.06 percent in treatment group and 70 percent, 60 percent and 30 percent in Control group respectively. It was concluded that MNFB feeding improved milk yield, milk fat, general health status and reproductive performance of buffalos, as it is a good source of protein, energy, and minerals. It is recommended that MNFB should be used as a supplementation in lactating buffaloes when they area fed with low quality fodder in arid and semi arid region.

The present study was conducted to determine the effect of increasing temperature humidity index (THI) on lactating Murrah buffalo. The study was conducted on six lactating buffaloes which were offered the same basal diet and were blocked by days in milk, milk yield and parity. The study was conducted during May, June and July with average THI of 79.88, 80.57 and 85.36, respectively. Milk yield was recorded twice a day at 06:00 and 18:00 h and physiological parameters were recorded and blood was sampled on 30th day of each month at 14:30 h. The results showed a significant decrease (P LT 0.05) in milk yield in buffaloes only at a THI of 85.36 as compared to THI up to 80.57. The rectal temperature (RT) did not change (P=0.580) with increasing THI up to 85.36, however, the respiration rate (RR) and pulse rate (PR) changed (P LT 0.05) progressively with increasing THI. Leucocytopnoea, lymphocytopnoea and neutrophilia; and alteration in serum urea, alkaline phosphatase activity, reactive oxygen species and phosphorus concentration were observed only at a THI of 85.36 as compared to THI up to 80.57. Similarly, significant (P LT 0.05) alteration in serum T4, cortisol and prolactin levels were observed at a THI of 85.36 as compared to THI up to 80.57. It can be concluded that lactating buffaloes experienced mild heat stress up to a THI of 80.57 (May and June) and a moderate type of heat stress at a THI 85.36 (July).

Flexor tendons of forelimb play a major role in the locomotion of the animal and also in bearing 45 percent of the body wieght, thus making these tendons prone to several injuries. Current investigation was carried in three post-natal age groups of buffalo bulls to elucidate gross morphological and morphometrical features of superficial (SDFT) and deep (DDFT) digital flexor tendons of forelimb. Morphological studies revealed that they are shiny white fibrous structures bound by tough, durable fibrous sheath the 'flexor retinaculum' on palmar aspect of manus in all three groups (G) i.e., 1 to 3 years (G I), 3 to 6 years (G II) and 6 years and above (G III). SDFT in cross sections at myo-tendinous junction was flat elliptical shaped in G I and G II whereas it was oval in G III specimens. At mid metacarpal region the SDFT was dorso-ventrally compressed and ring-shaped in digital region. Thickness increased in aged specimens at their origin, mid metacarpus and at insertion points. Lengths of the two slips of SDFT in buffalo gradually increased from inter digital space up to their insertion points from G I to G III. Cross sectional profile of DDFT in mid metacarpus was flat elliptical in outline in all groups. Thickness of the tendon steadily increased with age from G I to III. Length of DDFT from origin to its division and from division to insertion steadily increased.
