Cattle are among the most important domesticated bovid species in world, of which Ethiopia possesses large populations adapted to different agro-ecologies and production systems. Though several molecular population genetic studies have been done on Ethiopian indigenous cattle, genomic diversity selection signatures pertinent adaptation local environments yet be comprehensively characterized. He...

Vechur cattle, an indigenous breed of Kerala and it is the smallest cattle in world. They are highly disease resistant. The occurrence mastitis very Rare this as compared to crossbred cattle. Rearing these more cost effective they require less feed. Therefore, characterisation factors involved immune system breeds might provide insight into mechanisms variation resistance. Toll-like receptors (...

Male reproductive performance has more impact on overall herd productivity than in the female. In order to assess herd productivity in cattle in Nyagatare, Eastern Rwanda, the proportional distribution of male reproductive organ abnormalities was investigated in 3087 bulls slaughtered over a 4-year period. The aim of the study was to investigate the proportional distribution of male reproductiv...

BACKGROUND Reproductive diseases limit the productivity of cattle worldwide and represent an important obstacle to profitable cattle enterprise. In this study, herd brucellosis and bovine genital campylobacteriosis (BGC) status, and demographic and management variables were determined and related to predicted calving rate (PrCR) of cattle herds in Adamawa, Kaduna and Kano states, Nigeria. Serum...

Vechur cattle, an indigenous breed of Kerala are highly disease resistant. Toll-like receptors (TLRs) perform a vital role in disease resistance through their recognition of pathogen associated molecular patterns (PAMPs). In this study, the mRNA of Toll-like receptor 4 (TLR4) gene of Vechur cattle was sequenced, characterized and compared with other species. Total RNA from milk somatic cells of...

INTRODUCTION Bovine tuberculosis (BTB) is widespread yet poorly controlled in Nigeria hence posing a public health threat. This study determined the prevalence of Mycobacterium tuberculosis complex (MTC) and factors associated with MTC among slaughtered cattle at Jos South Abattoir in Plateau State, Nigeria. METHODS We conducted a cross sectional study in which we collected 168 lung samples s...

Whole-genome sequencing provides a powerful tool to obtain more genetic variability that could produce a range of benefits for cattle breeding industry. Nanyang (Bos indicus) and Qinchuan (Bos taurus) are two important Chinese indigenous cattle breeds with distinct phenotypes. To identify the genetic characteristics responsible for variation in phenotypes between the two breeds, in the present ...

during spring, summer and winter seasons, sistani donor cows, with normal reproductive status, were superovulated and embryos were recovered non-surgically on day 7. grade a blastocyst embryos were either transferred fresh (spring) or frozen (summer and winter). recovered embryos during summer and winter were exposed to glycerol and frozen using conventional method. during spring season, recipi...
