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).

The objectives of this study was to compare morphological characteristics and to establish evolutionary relationship of 14 Thai dwarf buffaloes and 21 swamp buffaloes based on mitochondrial DNA (mtDNA) D-loop variations. Morphological characteristics could be constructed phylomorphologic tree and showed clearly classified between dwarf and swamp buffaloes. Most of morphologic traits were highly significant difference adult contest swamp buffaloes (P LT 0.01) from 9 contest swamp buffaloes. Only morphological traits of length between eye, length between base of horn, horn length and horn width were not significant difference (P GT 0.05). Average shoulder height of Thai dwarf buffaloes were 108.33+-2.08 cm, whereas average shoulder height of contest swamp buffaloes were 156.78+-4.21 cm. Thai dwarf buffaloes would be defined as disproportional dwarfism. Sequences of mtDNA D-loop (374 bp) of dwarf and normal swamp buffaloes with reference sequences showed 84 polymorphic sites and defined as 12 and 11 haplotypes, respectively. It was noticed that transversion in Thai dwarf buffaloes occurred twice time of normal swamp buffaloes. Phylogenetic tree showed 2 clades of water buffaloes. Swamp buffaloes were classified into lineage A and lineage B, in which lineage A was more predominant than lineage B. Median joining network showed 2 clades of river and swamp buffaloes. Swamp buffalo (SaenCP) in lineage A1 seem to be ancestral node of some Thai swamp buffaloes, Chinese swamp buffaloes and Philippines carabao. Most of dwarf swamp buffaloes were in lineage A2 and dwarf swamp buffalo with no horn, black color- coat was latter evolution.

In this study, the status of water buffalo breeding in each geographical region in Turkey was examined, and the activities of enterprises were analysed from technical and economic perspectives. Four regions and the cities in these regions where buffalo breeding was concentrated in Turkey were chosen by Purposive Sampling Method, considering the number of water buffaloes, milk production and their share in the buffalo population and buffalo milk production in Turkey. A total of 462 sample enterprises were chosen from these cities by Stratified Random Sampling Method. The research data were collected through the questionnaires administered in face-to-face interviews with the producers. The data collected reflect the buffalo production in Turkey in 2014. The study examined socio-economic structures of the enterprises, revealing their capital structures and annual economic activities. The Marmara region ranked first in the time spent in buffalo breeding (26.62 years). Gross profit income was positive in four regions. Absolute profit and relative profit indicators were negative for farms in the Black Sea region and favourable for farms in other regions. For the development and promotion of buffalo breeding, the breeders should be further educated about better breeding practices, small enterprises should be modernized and expand their operations, efforts for the betterment of breeding practices should be intensified, existing wetlands should be protected and enhanced, the production costs (feed cost etc.) should be reduced, state subsidies should be granted to real producers, the public should be educated about the high nutritional value of water buffalo meat and milk through promotional campaigns, and buffalo producers should be better organized in producer unions.

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 to identify specific acoustic features which could be used as possible indicators for early diagnosis of pneumonia in buffalo calves. In pneumonia, change in elasticity and resonance of vocal sound producing organs occur which eventually affects the vocal signature of calves. Twenty Murrah buffalo calves' voice was recorded during both healthy and pneumonia infected stage where pneumonia was confirmed by lung X-RAY radiography. From the recorded vocal sound, acoustic features viz. call duration (sec.), call interval (sec.), frequency (Hz), bandwidth (Hz) and peak amplitude (P) with their sub variants were extracted with the help of PRAAT 3.2.36 software. Out of these, call duration (sec.) (0.879+-0.29 v/s 0.689+-0.24), call interval (sec.) (0.288+-0.059 v/s 0.107+-0.047) and peak amplitude (P) (start (0.750+-0.118 v/s 0.435+-0.113), end (0.102+-0.045 v/s 0.508+-0.268) and maximum (0.938+-0.210 v/s 0.684+-0.480)) were found significantly (p LT 0.05) different between two groups. Rest acoustic features did not differ statistically between two groups. This study indicates that it is possible to discriminate pneumonia voice from normal/healthy voice by acoustic analysis and farmers can acquire an early warning of pneumonia infections in calves through this non-invasive method.

Cryopreservation is connected with increased undesirable premature sperm capacitation, reduced lifespan and fertility results. Taurine acts as an antioxidant improving the semen quality after cryopreservation. The objective of the current study is to assess the effect of addition of different levels of taurine amino acid to tris-extender on bull sperm cryo-preservability. Methods: The collected semen samples were pooled and diluted with tris-citric acid-fructose egg yolk extender (control, 0 percent taurine) and different concentrations of taurine (10 mM, 20 Mm, 30 Mm, 40 Mm, 50 Mm, 60 Mm, 70 Mm, 80 Mm, 90 Mm and 100 mM) to final concentration of 60 *10**(6) motile sperm/ml. Diluted semen was processed for freezing and evaluated for sperm parameters. Results: Data showed that taurine enriched extender improved sperm parameters during cooling. Post thawing sperm motility percent, membrane integrity percent, Alive sperm percent improved and the percentages of abnormal sperm was lowered upon using taurine enriched extender. Conclusion: It could be concluded that, most the concentrations of taurine in Tris-citrate egg yolk extender ameliorated the post cooling and post freezing semen quality in buffalo bulls.
