This trial was conducted to check the effect of commercially available hydrolysable tannin (Silvafeed Bypro) on feed intake, protein digestibility, rumen pH, ammonia nitrogen and blood urea nitrogen in Nili Ravi buffalo bulls. Four cannulated buffalo bulls were alloted in 4*4 Latin Square Design. The diet consisted of 50% seasonal fodder and 50 percent concentrate. Four iso-caloric (ME: 2800 kcal/kg) and iso-nitrogenous (CP: 18 percent) concentrate rations T1, T2, T3 and T4 were formulated and supplemented with 0, 10, 20 and 30 g hydrolysable tannin respectively per animal on daily basis. Diets as a total mixed ration were given to the bulls ad libitum twice a day. The results showed that adding tannin in diet had unaltered effect (P GT 0.05) on feed intake, digestibility of crude protein, ruminal pH, ammonia nitrogen and blood urea nitrogen. However, slightly increased numerical values were found for feed intake, crude protein digestibility and ruminal pH while slightly decreased numerical values were found for ruminal ammonia nitrogen and blood urea nitrogen at different inclusion levels of hydrolysable tannin in diet. It is concluded that numerical values for feed intake, crude protein digestibility, ruminal pH, ammonia nitrogen and blood urea nitrogen are slightly better but non-significant than control when buffalo bull were fed diets supplemented with hydrolysable tannin.

Thirty-six healthy Tarai buffaloes (280-350+-10 kg body weight, 2nd to 4th parity) were selected to investigate their milk composition. The selected animals were divided into four groups having nine buffaloes in each group as, each group from early, mid and late lactation and another group of dry buffaloes. The study carried out in four seasons and climatic variants of temperature and relative humidity were recorded for each month where temperature-humidity index (THI) was calculated. Results of milk composition with advancing in lactation stage showed significantly (P LT 0.05) higher values for milk fat, urea and total solids. In season-wise, milk constituents of fat, protein and total solids were found significantly (P LT 0.05) higher during winter season except higher milk urea in summer season. Other milk constituents include lactose, SNF and pH were remain unaffected throughout the lactation period and seasons. Milk somatic cell count (SCC) is affected by both lactation period and seasons but the variations stood non-significant. Calculated THI in tarai region was found higher (79 LT THI LT 84) during summer and rainy seasons. It may be concluded that Tarai buffalo performances are affected by seasonal variations and lactation period as indicated in milk composition variations. Thus, Tarai buffalo could perform better if improvement in their management system of housing and feeding of quality nutrients.

In present investigation therapeutic efficacy of three most commonly used anti-trypanosomal drugs (isometamidium chloride hydrochloride, diminazine aceturate, and quinapyramine sulphate) were studied. Evaluations of therapeutic efficacy were assessed done on the basis of percent recovery assessment, hematological and biochemical alteration on day 0, day 7th and day 14th post treatment. All three drugs were found effective against the trypanosomosis in buffalo but the extent of improvement in terms of hematological values, biochemical values and percent recovery was observed maximum in the treatment with isometamidium chloride hydrochloride followed by diminazene aceturate and least with the quinapyramine sulphate.

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.

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.

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.
