“…*P < 0.05, **P < 0.01, ***P < 0.001. cholesterol level observed in group FR may be because of the higher physical activity performed by the heifers kept on pasture. Cholesterol, a precursor molecule needed in the biosynthetic pathway of steroid hormones, is related to the ovarian functional activity (Das and Khan, 2010). The physiological levels observed by other authors in adult cyclic female buffaloes ranged between 2.08 and 3.78 mmol/l (Campanile et al, 1998;Das and Khan, 2010), whereas lower values were found in acyclic Murrah buffalo heifers (Anand and Prakash, 2008), and even lower levels (1.80 mmol/l), similar to those observed in this study, were observed by Borghese et al (2010) in a study on buffalo young bulls.…”

In order to evaluate the influence of rearing system (free-ranging (FR) v. confinement (C)) on buffalo heifer efficiency to reach age of puberty and on behavioural and immune functions, two experiments were conducted from September 2010 to October 2011. In Experiment I, 32 subjects aged 8 to 9 months at the start of experiment were used. A total of 16 animals (group C) were group housed in an indoor slatted floor pen (4 m 2 /animal) with an outdoor paddock (4 m 2 /animal); 16 others grazed on a Mediterranean natural pasture of 40 ha (group FR). Behavioural data were collected and organic matter digestibility, blood metabolites and progesterone were determined. At the end of the experiment, a novel object test and a skin test were conducted, and the avoidance distance (AD) at the manger was measured. Free-ranging animals were able to express natural behaviours such as wallowing and grazing. C animals devoted more time to the novel object than FR animals, whereas AD at manger was lower in group FR than in group C ( P < 0.01). Cellular immune response was higher in FR heifers than in C animals ( P < 0.01). FR animals also showed a higher digestibility of organic matter ( P < 0.01). Heifers from group FR had higher plasma concentrations of non-esterified fatty acids ( P < 0.001) and lower concentrations of glucose than heifers from group C ( P < 0.001). C animals showed higher daily weight gains ( P < 0.01) and weight at the puberty ( P < 0.05), but there were no differences in terms of age of puberty between the two groups. The intakes of dry matter (DM), CP and energy to reach the age of puberty were similar in both groups. In order to verify whether the results obtained in Experiment I could be replicated in different rearing conditions (reduced pasture availability, different location and altitude), a second experiment was conducted on 26 animals, where only onset of age of puberty and metabolic profile were monitored. In Experiment II, 13 heifers grazed on a natural pasture of 5 ha, other 13 received the same space as indicated for Experiment I. Results from Experiment II generally confirmed those of Experiment I. Only the intakes of DM and energy to reach the age of puberty were higher in group C than in FR ( P < 0.001). A lower competition with human nutrition, reproductive performances similar to those shown by confined animals and the indications given by immune and behavioural variables, suggest that a free-range-based system may be conveniently used for buffalo heifer farming purposes.

:The polymorphisms of several genes including Leptin (LEP), beta-lactoglobulin (LGB) and Prolactin receptor (PRLR) have been shown to affect milk composition traits in dairy cattle. But, the effects of these polymorphisms on the milk traits of Philippine water buffalo are still unclear. In the Philippines, buffalo are the major milk producers most of which are the Philippine carabao (PC), the American Murrah Buffalo (AMB) and Bulgarian Murrah Buffalo (BMB). The LEP, LGB and PRLR genes are considered to be associated with milk production traits. The objective of the present study was to identify the single nucleotide polymorphisms (SNPs) in the LEP, LGB and PRLR genes of PC, AMB and BMB and to investigate the effect of the SNPs on milk production traits in these buffalo. Genetic polymorphisms were screened by DNA sequencing and 12 SNPs were detected in BMB; 5 SNPs were in LEP exon3 region (G14227A, G14343A, T14502C, C14526T, G14603A); 5 SNPs were in LGB exon 2 region (G1861C, A1900G, G1901T, T1948C, G1949A); 2 SNPs were in PRLR exon 6 (T59047C, T59109C). Also, 12 polymorphism sites between cattle and buffalo were identified. Our analysis of the association between SNPs and milk production traits should be useful in future studies of buffalo breeding to improve lactation performance.

Abstract:The objective of this review is to draw the present scenario of dairy buffalo production in Bangladesh and their contributions to the national economy. Buffaloes in Bangladesh are mostly indigenous type encompasses with swamp and river and are distributed throughout the country. However, the population is higher in coastal part, Meghna-Ganga and Jamuna-Brahamaputra flood plain, considered to be the buffalo pockets. The total buffalo population is 1.471 million which are mostly managed in household subsistence farming as well as bathan in coastal region. Buffaloes are normally used as a draught animal and in lower extent partially for milk and meat production. Most of the farmers are rural small holders; traditionally practiced croplivestock integration upon which the management practices of buffalo usually depends. Buffaloes are raised in homestead and approximately 5-7 hours were grazes per day in household farming. Small amount of concentrate is usually offered to buffalo during dry season only by the economically viable farmers. On the other hand, in bathan, farmers are fully depended on grazing at public fallow land. Lower milk production efficiency, poor reproductive performance followed by under nutrition and low growth rate in buffaloes resulted insignificant contribution to the national economy of Bangladesh. Balanced nutrition and better management practices can improve buffalo productivity. In order to do so, a number of issues are required to be addressed such as establishment of nutrient requirements for dairy, development of buffalo calf feeding systems, artificial insemination technique, nutritional management of metabolic and reproductive anomalies, and understanding and exploitation of the buffalo gut ecosystem. Productivity of buffaloes can be mainly depended on genetic improvement, good nutrition, good management and also climatic conditions of an area. Extensive coordinated research and extension efforts are required for increasing dairy buffalo production in this country.
