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 present study was conducted to investigate the normal somatic cell count (SCC), associated factors in hygienic management and to define subclinical mastitis in buffaloes in Puducherry. Samples were collected from 50 clinically normal buffaloes stationed at different farms of Puducherry region. Somatic cell count was measured for all the milk samples using Newman-Lampert staining technique. The upper limit of SCC was determined as GT= 2, 00,000/ml of milk based on the mean +- 2SD of a total SCC. California mastitis test (CMT) was conducted for all the animals. In the present study subclinical mastitis was diagnosed on the basis of samples with SCCs GT= 2, 00,000/ml. In the present study 96 percent of the milk samples were negative for California mastitis test (CMT). The SCC of CMT positive quarter was significantly higher (P LT 0.01) than CMT negative quarters. Subclinical mastitis was found only in three buffaloes in the present study. Somatic cell counts were significantly higher in the buffaloes with subclinical mastitis. Regarding the hygiene, all the farms had poor management and improper housing. Proper education on hygienic management is need of the hour for buffalo owners of Puducherry region.

Milk fatty acid composition of Murrah buffaloes was determined in present study. Samples were collected from 10 lactating buffaloes and were analysed for fatty acid profile using AOCS official method. Murrah milk fat was having 71.6 percent saturated fatty acids (SFA), 27.97 percent unsaturated fatty acids. C16:0, C18:1c, C18:0, C14:0 and C12:0 were the five most abundant fatty acid (82.5 percent of total fatty acids) in the Murrah milk. Palmitic acid, myristic acid (14:0) and stearic acid (18:0) together constituted approximately 85.8 percent of saturated fatty acids by weight. Short chain fatty acids (C4:0, C6:0), medium chain fatty acids (C8:0, C10:0, C12:0), and long chain fatty acids (C16:0, C18:0, C16:1, C18:2) were 1.82, 4.56 and 49.96 g/100 g respectively. Mono-unsaturated fatty acid were 26.79 percent of the fatty acids in milk, mostly oleic acid (18:1). Poly-unsaturated fatty acids constitute about 1.18 percent by weight of the total fatty acids. Linoleic acid (18:2) and alpha-linolenic acid (18:3) accounted for 0.88 and 0.30 percent by weight of the total fatty acids.

In this research, Data of milk yield, fat and protein percentage of Khuzestani buffalo were used. The daily records of milk yield were collected in the south-west of Iran where buffalo experienced a hot climate. The data set was constructed with 8,123 records of 1,430 first lactation buffalo. A univariate random regression model (RR/CF) was applied to data. Regression of additive genetic effect based on Legendre polynomials from the day of lactation was considered in the model. The results showed that maximum residual variance for the milk and fat production was estimated at the beginning of the lactation period. The minimum amount of additive genetic variation of milk and fat traits was seen in the early lactation period and the maximum amount of the component was estimated at the end of the lactation period. The lowest heritability of the mentioned traits was at the beginning of the lactation period. The level of this parameter increased to mid-lactation and was at its maximum during the late months of lactation, then decreased to the end of lactation. The estimated additive genetic correlations between close test-days were higher than faraway test-day records for each milk yield and milk fat content. Based on the results of this study, a random regression model with fitting orders 3 and 4, seems to be suitable for additive covariance functions in order to analyze the milk test-day records of buffaloes.

Raw milk samples of 503 individual buffaloes were collected from dairy farms located in Agra and Mathura cities in North India. Multiple tests (Indirect Fluorescent Agglutination test (i_FAT), IS900 PCR, Microscopy, Indigenous ELISA kit (i_ELISA), Dot-ELISA (d_ELISA) and Latex agglutination test (LAT)) based bio-load and bio-type profile of Mycobacterium avium subspecies paratuberculosis (MAP) was studied. Cumulatively average bio-load was 61.2 percent using three antigen and three antibody based. In i_FAT, IS900 PCR and microscopy, 43.5, 13.3 and 40.9 percent milk were positive for MAP, respectively. Whereas, 32.8, 49.3 and 44.1 percent milk samples were positive in i_ELISA, d_ELISA and LAT, respectively. Bio-typing of representative milk samples using IS900 PCR positive raw milk (67), 13.4 percent were infected with 'Indian Bison Type' biotype using IS1311 PCR_REA. Study concluded that 'Indian Bison type' was the predominant bio-type infecting lactating buffaloes of this region. Raw milk was highly convenient sample in buffaloes and 'milk samples' were first time screened without initial processing of milk samples. Detection limits of each tests was improved. Results of five tests (d_ELISA, LAT, i_ELISA, microscopy, i_FAT were comparable, except IS900 PCR. High bio-load of MAP in milk of buffaloes was major health hazard for human health. High bio-load of MAP was alarming and calls for initiation of Johne's disease control programs in the country.

This study aimed to determine the lactoferrin concentration from healthy and subclinical mastitic buffaloes. Lactoferrin levels were determined in a total of 475 mammary quarter milk samples, 391 of which were healthy and 84 suffering from subclinical mastitis. The mean milk lactoferrin level in logarithmic form for healthy and subclinical mastitic milk samples was 1.34+-0.27 and 1.85+-0.47, respectively. A significant difference (p LT 0.001) was determined between the two groups in terms of the lactoferrin levels. The milk lactoferrin levels in healthy buffaloes were significantly higher in the middle and late periods of lactation than the peak period (p LT 0.05). The mean milk lactoferrin levels in subclinical mastitic buffaloes infected with S. aureus or S. agalactiae were significantly higher than those from in buffaloes infected with Coagulase-Negative Staphylococci (CNS) or Candida spp. (p LT 0.05). An increase in milk lactoferrin levels was observed in parallel with the increase in somatic cell scores. In conclusion, milk lactoferrin levels in buffaloes were found to increase with the lactation stage, the presence of bacterial infection and the somatic cell count. This is the first study to determine the relationship between lactoferrin concentrations and bacterial infection in milk obtained from mammary quarters with subclinical mastitis in Anatolian buffaloes.

The objective of the present study was to identify the physico-chemical differences between experimentally fraudulent cheeses and those produced exclusively with cow and buffalo milk and to sensorially assess the consumer's perception of these products. Three types of cheese were produced using buffalo milk and cow milk as raw materials at different proportions, and total lipids were analysed; protein ash, moisture and carbohydrate contents were measured; energy values were determined; and affective sensory and purchase intent analyses were performed. The results indicated that 57 percent and 59 percent of the judges, respectively, reported liking the colour and texture of the mixed cheese very much and that they would certainly buy it. Regarding the composition, the fraudulent cheese had a lower energy value compared to the cow and buffalo cheeses and that the protein content of the fraudulent cheese was lower than that of the buffalo cheese. There were no significant differences in the carbohydrate or fat contents among the analysed products. Compared with the cow cheese, the mixed cheese and buffalo cheese had higher moisture contents. It was concluded that although the mixed cheese presented significant physico-chemical differences, it was considered acceptable product because consumers showed intent to purchase the mixed cheese.

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.

The present study was undertaken (1) to characterize the FA composition particularly on the concentration of conjugated linoleic acid (2) to investigate of physicochemical properties of Anatolian water buffalo milk, and from six different provinces in Turkey. The fat amount in water buffalo milk samples were in the range of 5.97+-0.30 percent to 9.19+-0.57 percent and the mean fat was 6.96+-0.25 percent. The main individual FA in water buffalo milk were in the order 16:0, 18:1 cis-9, 14:0, and 18:0. The CLA, bovinic acid (cis-9, trans-11), represented 1.09+-0.06 in water buffalo milk. Saturated fatty acids (SFA) were the potent fraction in water buffalo milk fat (70.63+-0.7), MUFA and PUFA were 29.37+-0.7 and 0.2+-0.03, respectively. The data exhibit statistically differences (P LT= 0.05) in the proportions of individual FA were detected among different provinces in Turkey. Anatolian water buffalos were poor in terms polyunsaturated FA compared to other water buffalos from different countries. Therefore, these results may provide useful information about the nutrient composition of buffalo milk and further studies are warranted to improve the technological and nutritional characteristics of Anatolian buffalo milk.
