Abstract The research was conducted to observe morphometric characteristics of Limousin-Bali crossbred cows in Lombok Tengah Regency, West Nusa Tenggara. Data were collected using purposive sampling technique with cattle measured including Bali and crossbred. material used 60 head which consisted 30 (Limbal) cows. kept loose pens a litter base. feed provided forages as well drinking water is fr...

CD14 is an important molecule for innate immunity that can act against a wide range of pathogens. The present paper has characterized CD14 gene of crossbred (CB) cattle (Bos indicus×Bos taurus). Cloning and sequence analysis of CD14 cDNA revealed 1119 nucleotide long open reading frame encoding 373 amino acids protein and 20 amino acids signal peptide. CB cattle CD14 gene exhibited a high perce...

The effects of anabolic implants, growth phase (growing vs finishing) and rate of growth on the priorities for protein and fat deposition were determined in yearling cattle. Santa Gertrudis crossbred yearling steers weighing 290 kg were individually fed diets varying in forage and grain content and either not implanted (n = 16) or implanted (90-d intervals) with Ralgro (n = 13) or Synovex-S (n ...

The objective of the present study was to estimate the allele and genotype frequencies of the CSN3/HinfI and LGB/HaeIII gene polymorphisms in beef cattle belonging to different genetic groups, and to determine the effects of these polymorphisms on growth and carcass traits in these animals, which are submitted to an intensive production model. Genotyping was performed on 79 Nelore, 30 Canchim (...

Eighty-four Bos taurus crossbred steers were used to investigate effects of level and duration of limit-feeding feedlot cattle in a hot environment. Pens (four/treatment) of steers (seven/pen) were fed feedlot finishing diets and randomly assigned to the following treatments: 1) restricted to approximately 75% of feed consumed when offered ad libitum for 21-d duration (RES21); 2) restricted to ...

The Genetic Basis For Increased Productivity Considerable research by various State Agricultural Experiment Stations and the USDA has clearly demonstrated the potential for increasing beef cattle productivity through crossbreeding. Consequently, the use of crossbreeding for the commercial production of beef is rapidly increasing. Crossbreeding (the mating of animals from different breeds) is si...

Infertility and subfertility negatively impact the economics and reproductive performance of cattle. Of note, significant pregnancy loss occurs in cattle during the first month of pregnancy, yet little is known about the genetic loci influencing pregnancy success and loss in cattle. To identify quantitative trait loci (QTL) with large effects associated with early pregnancy loss, Angus crossbre...

Fascioliasis, or trematode infestation, is an important disease caused by Fasciola hepatica and Fasciola gigantica. Both species are hepatic parasites that affect humans. We have examined the zoonotic aspects of fascioliasis. A total of 80 fresh liver samples were collected from 67 Kedah-Kelantan crossbred cattle and 13 Murrah buffalo at 4 local abattoirs in Perak, Malaysia. The samples were ex...

The authors describe a serological survey on the prevalence of infectious bovine rhinotracheitis (IBR) among cattle and buffalo (Bubalus bubalis) in three southern states of India. A local isolate of bovine herpesvirus 1 (BHV-1) from an outbreak of the respiratory form of IBR was used as a source of virus antigen in avidin-biotin enzyme-linked immunosorbent assay (ELISA). The overall prevalence...

Background: Cellular tolerance to heat stress is mediated by shock proteins (HSPs). The HSPs act as molecular chaperones and are transcribed in response stress. Among different families of these proteins, HSP70 considered be related the development temperature tolerance. Unraveling polymorphism protein genes could a step towards identification genetic markers for selecting heat-tolerant cattle....
