The present research experiment was carried out to evaluate the effect of GnRH and PGF2α administration on post partum fertility in retained placenta buffaloes. Total thirty six Murrah buffaloes with retained placenta condition were selected and the placentas were removed manually and intra-uterine boluses were kept (3 boluses per day for 3 consecutive days post-partum) in experimental buffaloe...

Diacylglycerol O-acyltransferase 1 (DGAT1) is a microsomal enzyme that catalyzes the final step of triglyceride synthesis. The DGAT1 gene is a strong functional candidate for determining milk fat content in cattle. In this work, we used PCR-SSCP (polymerase chain reaction-single-strand conformation polymorphism) and DNA sequencing to examine polymorphism in the region spanning exon 7 to exon 9 ...

The data pertaining to variable production and reproduction traits of Murrah buffaloes (1980 lactation records of 698 Murrah buffaloes) were collected from the Central Cattle Breeding Farm, Alamadhi, Tamil Nadu, India. The overall leastsquares means (± SE) for peak yield, days to attain peak yield, 305-day milk yield, lactation length, lactation milk yield, service period, calving interval and ...

Data of 698 Murrah cows sired by 43 bulls maintained at the Central Cattle Breeding Farm, Alamadhi were analysed to study the performance of Murrah buffaloes at the coastal region of Tamil Nadu, India. Least-squares means and genetic parameters were estimated for different first lactation traits. The averages for 305-day and total lactation milk yields were 1616.3 ± 39.6 and 1686.2 ± 44.4 kg, r...

Heat stress has adverse effects on fertility of dairy animals. Decline in fertility is linearly associated with an increase in combination of both temperature and humidity. The purpose of this study was to investigate the relationship between temperature humidity index (THI) and the pregnancy rate of Murrah buffaloes in a subtropical climate. The effects of genetic and non-genetic factors viz.,...

AIM Objective of the present study was to investigate the relation between antioxidant status and postpartum anestrous (PPA) condition in Murrah buffalo. MATERIALS AND METHODS Jugular blood samples were collected from two different groups of Murrah buffaloes each group consisting of 20 animals. Group I was of PPA and Group II were of cyclic buffaloes. The animals selected were examined for co...

The present study was designed and conducted to fi nd the appropriate physical baseline values for hepatobiliary enzymes such as, alanine aminotransferases (ALT), aspartate aminotransferases (AST), alkaline phosphatase (ALP) and gamma glutamyltransferases (GGT) in adult healthy Murrah buffaloes in hot humid climatic conditions and also to assess the ideal storage condition for buffalo sera samp...

In order to contribute to the genetic breeding programs of buffaloes, this study aimed to determine the influence of environmental effects on the stayability (ST) of dairy female Murrah buffalo in the herd. Data from 1016 buffaloes were used. ST was defined as the ability of the female to remain in the herd for 1, 2, 3, 4, 5 or 6 years after the first calving. Environmental effects were studied...
