The transmission of diseases between livestock and wildlife can be a hindrance to effective disease control. Maintenance hosts and contact rates should be explored to further understand the transmission dynamics at the wildlife-livestock interface. Bovine tuberculosis (BTB) has been shown to have wildlife maintenance hosts and has been confirmed as present in the African buffalo (Syncerus caffe...

Four ruminally cannulated buffalo bulls (300 kg) were fed mottgrass diets using a 4 4 Latinsquare design. Treatments consisted of mottgrass fertilized with 0 or 110.4 kg N/ha and harvested at 40 (ECM) and 60 (LCM) days. Fertilization increased the concentrations of crude protein (CP) and fibre contents. The CP contents of the mottgrass decreased and fibre contents increased with advancing matur...

Conventional buffalo semen freezing studies are limited in Anatolian buffaloes, which overly sensitive to exogenous stimulation. The present study's object was determine the main features of obtained by artificial vagina method for first time. A total number 150 ejaculates were collected from three Buffalo bulls (app. 4 years age). mean pH, volume and concentration found 6.63±0.15, 1.61±0.5 ml,...

Several 1-acylglycerol-3-phosphate-O-acyltransferases (AGPATs) can acylate lysophosphatidic acid to produce phosphatidic acid. Of the eight AGPAT isoforms, AGPAT6 is a crucial enzyme for glycerolipids and triacylglycerol biosynthesis in some mammalian tissues. We amplified and identified the complete coding sequence (CDS) of the water buffalo AGPAT6 gene by using the reverse transcription-polym...

Carcass EPDs are becoming common in this era when more economically important traits are being added to national cattle evaluation programs. Traditionally, carcass traits were evaluated solely using progeny tests. One limitation to progeny testing is, of course, cost. Also, for bulls to be evaluated in such a program, he must produce progeny on which carcass data are collected. This is a proces...

AIM To study the effect of preputial washing on bacterial load, preservability and semen quality in Murrah buffalo bulls. MATERIALS AND METHODS A total of 36 collections of three Murrah buffalo bulls maintained at Artificial Breeding Research Centre, ICAR-National Dairy Research Institute, Karnal, were collected at weekly intervals from each bull without preputial washing and latter ejaculate...

Deoxyribonucleic acid was influenced by sperm ageing and sperm storage temperature. In this study, the effect on DNA integrity at pre-freeze and post-freeze stages was analyzed by single cell gel electrophoresis during winter and summer seasons. Traditionally, the diagnosis of male infertility depends on microscopic assessment and biochemical assays to evaluate quality of semen. These tests are...

Objective of the present study was to document the semen producing ability, productive life and genetic ability for lactation milk yield of Sahiwal bulls used for artificial insemination (AI) in Punjab and to find the impact of AI bulls on the improvement of Sahiwal cattle. Data from Semen Production Unit (SPU), Qadirabad, Sahiwal, Pakistan were used for this purpose. A repeatability animal mod...

Artificial insemination (AI) subfertility is an indication of failure of AI with frozen-thawed sperm classified as normal by conventional semen examination. Recently, 8 AI-subfertile Japanese Black cattle (S1-S8) were identified using the routine AI test or in vivo fertilization test, which included AI with frozen-thawed sperm of superovulated females and subsequent non-surgical recovery of pre...

ISSN 1652-6880, ISBN 91-576-7263-6 In this thesis work we tested the hypothesis that tropical climatic conditions affect the quality of fresh and frozen-thawed (FT) spermatozoa from swamp buffalo bulls used for artificial i...
