The aim of the present study was to determine follicle development and resumption of ovarian activity in Bulgarian Murrah buffaloes by transrectal ultrasonographic monitoring of the ovaries during the first 50 days after after calving throughout the breeding season. The investigation included 18 clinically healthy Bulgarian Murrah buffaloes divided into two groups: Group I (n=8, primiparous buf...

A total of 1474 and 1935 production and reproduction records of crossbred cattle and Murrah buffaloes from the year 1992 to 2012 were utilized in the present study to investigate breeding efficiency (BE) and various performance traits. Breeding efficiency was calculated using Wilcox and Tomar methods and Least –squares of Harvey model was used to study the effects of various non-genetic factors...

A feeding trial was conducted in graded Murrah buffaloes to study the influence of yeast culture (Saccharomyces cerevisiae CNCM I-1077 strain) supplementation on intake and nutrient utilization. 12 graded Murrah buffaloes with an average body weight of 465.4 ± 20.92 kg were randomly divided into two groups (Control and treatment) of 6 animals each. Animals in both the groups received a basal di...

The present study was conducted on the Murrah buffaloes maintained at Livestock Research Centre of ICAR-National Dairy Research Institute (NDRI), Karnal. The animals were classified into heifer, primipara and pluripara. For this experiment a total of 50 Murrah buffaloes were followed, out of which 8 were heifers, 12 were primipara and 30 were pluripara. Daytime was considered to be from 6.00 am...

AIM The aim of the present study was to assess the influence of temperature and humidity prevalent under subtropical climate on the breeding values for fertility traits viz. service period (SP), pregnancy rate (PR) and conception rate (CR) of Murrah buffaloes in National Dairy Research Institute (NDRI) herd. MATERIALS AND METHODS Fertility data on 1379 records of 581 Murrah buffaloes spread o...

The present study was carried out to evaluate the effect of prill fat and rumen protected choline supplementation on daily dry matter intake, body weight changes and economics in lactating Murrah buffaloes (n=18) divided into three equal groups (Control, T1 and T2). Buffaloes in all the three groups were fed similar basal diet as total mixed ration comprising of berseem green fodder, wheat stra...

Accepted: 21/05/2015 Abstract The present study was aimed to investigate liver function upon supplementation of vitamin E to dry Murrah buffaloes through analysis of serum enzymes. The Murrah buffaloes (n = 12) were selected during their late gestation from National Dairy Research Institute (NDRI) livestock herd and divided randomly into two groups, comprising of six each. Buffaloes of group I ...

Incidence S. nasale (causative agent of nasal schistosomiasis) in graded murrah buffaloes was studied. 4(8%) among healthy and 46(92%) among suspected buffaloes were diagnosed with nasal schistosomiasis. Area under investigation was highly irrigated giving ample scope for exposure of animals to cercaria of S. nasale. Buffaloes showing signs of reduced water intake, reduced milk yield, normal bo...

The objectives of this study were to test the efficacy of induction of estrus and determine the timing of ovulation in relation to preovulatory LH and estrogen surges in cycling Murrah buffaloes subjected to Heatsynch protocol (GnRH-PGF2α-Estradiol benzoate). In experiment 1, the buffaloes (n = 10) were treated with Heatsynch protocol and observed for estrus and ovulation. In experiment 2 and 3...

AIM To investigate the effect of pre-partum prilled fat feeding on dry matter intake (DMI), energy balance and milk production in Murrah buffaloes. MATERIALS AND METHODS Advance pregnant Murrah buffaloes were either received a dietary supplement of prilled fat at 100 g/day for 35 days pre-partum and at 150 g/day for 95 days post-partum (supplemented group [SG]) or did not receive fat suppleme...
