Fasciolosis, prevalence and economic losses in Bos Taurus

Biological Efficiency Differences Among Bos taurus x Bos taurus andBos indicus x Bos taurus F1-Cross Cows

Prevalence of liver condemnation due to bovine fasciolosis in Southern Espírito Santo: temporal distribution and economic losses.

The present study was conducted to evaluate the economic losses and temporal distribution of the prevalence of liver condemnation due to bovine fasciolosis. The abattoir in Atílio Vivácqua, in the South of the State of Espírito Santo, which is under state inspection by the veterinary service of the Livestock and Forest Protection Institute of Espírito Santo, was used as the data source. The pre...

A comparative study on urinary purine derivative excretion of yak (Bos grunniens), cattle (Bos taurus), and crossbred (Bos taurus x Bos grunniens) in the Qinghai-Tibetan plateau, China.

Two experiments were conducted to determine the urinary purine derivative (PD) excretion rates and to analyze potential variations in PD excretions between yak, Tibetan indigenous cattle, and their crossbreds under similar ecological environment, and to develop prediction equations based on PD excretion for estimating rumen microbial protein supply. Three Tibetan castrated male yaks, and simila...

Abnormal Bovine (Bos taurus L.) Karyotypes1

The addition of BUDR (5-bromodeoxiuridine), a thymine analogue, to cell cultures causes various chromosomic changes, depending on the length of treatment and when the BUDR is incorporated into the DNA molecule. A short BUDR treatment of cells in the second half of the S-phase causes symmetrical chromosome segmentation (Zacharov et al. 1971), while prolonged contact over two division cycles indu...

Differences in Beef Quality between Angus (Bos taurus taurus) and Nellore (Bos taurus indicus) Cattle through a Proteomic and Phosphoproteomic Approach

Proteins are the major constituents of muscle and are key molecules regulating the metabolic changes during conversion of muscle to meat. Brazil is one of the largest exporters of beef and most Brazilian cattle are composed by zebu (Nellore) genotype. Bos indicus beef is generally leaner and tougher than Bos taurus such as Angus. The aim of this study was to compare the muscle proteomic and pho...
