The objective of this study was to demonstrate differences in aspects of adipose tissue cellularity, lipid metabolism, and fatty and cholesterol composition in Angus and Brahman crossbred cattle. We hypothesized that in vitro measures of lipogenesis would be greater in three-fourths Angus progeny than in three-fourths Brahman progeny, especially in intramuscular (i.m.) adipose tissue. Progeny (...

Crossbreeding had been initiated and put into practice in various parts of Ethiopia for a very long time to improve milk yield performance. This review was conducted generating compiled information on production traits such as daily (DMY), lactation length (LL), cross breed dairy cattle Ethiopia. Review results performances varied greatly from one genotype another. The on-station yield, were ra...

The aim of the present study was to screen the genotype profile of bovine kappa-casein gene among Frieswal (HF × Sahiwal) crossbred cattle developed in India. A total number of two hundred Frieswal cows were evaluated for HinfI RFLP based genotyping of kappa-casein gene. We observed that only two genotypes (AA and AB) exist among the studied population with the genotype frequency of 0.58 (n=117...

In this paper, the potentials and constraints on estrus synchronization (ES) artificial insemination (AI) practice for dairy cattle producers were overviewed. Compared to other African countries, Ethiopia has large numbers of population. However, self-sufficiency in milk production is not yet attained due presence a lot limitations that hamper success ES mass AI many parts country such as impro...

AIM The objective of this study was to investigate the effect of genetic and non-genetic factors and estimate the genetic parameter for gestation length (GL) of Jersey crossbred cattle. MATERIALS AND METHODS The data included the 986 parturition records on Jersey crossbred cattle maintained at the Eastern Regional Station of ICAR-National Dairy Research Institute, Kalyani, West Bengal, India ...

ISSN 1652-6880, ISBN 978-91-85913-20-6 This thesis presents studies of the reproductive and lactation performance of dairy cattle in the Oromia Central Highlands of Ethiopia, with particular emphasis on diagnosing ...

Twenty-four mature, nonpregnant crossbred cows were used in a 42-d feeding study to evaluate the effects of dietary cation-anion difference (DCAD) on performance, dry matter intake, and pH of blood, urine, and uterine flushing. All cows were housed individually and provided free-choice access to bahiagrass hay and a corncottonseed meal supplement. Two treatments were randomly allocated to cows ...

The aim of this study was to evaluate the effect of eCG on fertility of crossbred (Bos taurus x Bos indicus) lactating cows submitted to a protocol of fixed time AI (FTAI) between October and November 2013. A total of 265 cows was used, 165 multiparous and 100 primiparous, with an average milk production of 24.3 ± 0.47 kg/d and average of 127.7 ± 5.38 DIM. At a random day of the estrous cycle a...

AIM The objective of study was to investigate the effects of drinking water on certain physiological parameters such as heart rate (HR), respiration rate (RR), rectal temperature (RT) and, ruminal motility (RM). MATERIALS AND METHODS The experiment was carried out on 18 farm bred lactating crossbred cows. The animals selected for the study were divided into three groups of six animals each on...
