PENGARUH BREED TERHADAP MOTILITAS SPERMA SAPI LOKAL INDONESIA DAN Bos taurus DI BALAI INSEMINASI BUATAN (Effect breeds on sperm motility of indonesian local bulls and bos taurus at Artificial Insemination Center)

Preweaning efficiency for mature cows of breed crosses from tropically adapted Bos indicus and Bos taurus and unadapted Bos taurus breeds.

Production data were collected on mature cows produced by mating Angus and Hereford (pooled AH), Brahman (Bh) and Boran (Br), and Tuli, a tropically adapted Bos taurus, sires by AI or natural service to Angus and Hereford cows. These cows were mated to Charolais bulls for the purpose of this study. Within each sire breed of cow, cows were assigned randomly to one of three feeding rates, 49 or 7...

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

Effects of scrotal insulation on sperm production, semen quality, and testicular echotexture in Bos indicus and Bos indicus x Bos taurus bulls.

The objectives of the present study were to evaluate the effects of scrotal insulation on sperm production, semen quality, and testicular echotexture in Bos indicus and Bos indicus x Bos taurus crossbred bulls. In one experiment, B. indicus bulls (n=12) were allocated to control and whole-scrotum insulation groups, while in a second experiment, crossbred bulls (n=21) were allocated into control...

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...

Effect of marbling degree on beef palatability in Bos taurus and Bos indicus cattle.

This study was designed to evaluate the relationship between marbling score and breed-type (Bos taurus vs < or = 1/4 Bos indicus) on palatability of cooked beef. One thousand six hundred sixty-seven steers and heifers (1,337 Bos taurus and 330 Bos indicus x Bos taurus crosses) that had been managed and fed alike were used. Shear force and tenderness rating indicated that meat from Bos indicus c...
