Synchronization of Bos Indicus-influenced Cattle for Timed Artificial Insemination
Developing successful methods for synchronizing estrus and ovulation in cattle has been a major research interest for at least the last 35 yr. Early objectives focused on the control of the corpus luteum (CL) and artificial insemination (AI) relative to estrus. Ultimately, the goal has been to achieve precise synchronization of ovulation so that cattle can be inseminated without regard to estru...
متن کاملEffect 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...
متن کاملBill E. Kunkle Interdisciplinary Beef Symposium: Temperament and acclimation to human handling influence growth, health, and reproductive responses in Bos taurus and Bos indicus cattle.
Temperament in cattle is defined as the fear-related behavioral responses when exposed to human handling. Our group evaluates cattle temperament using 1) chute score on a 1 to 5 scale that increases according to excitable behavior during restraint in a squeeze chute, 2) exit velocity (speed of an animal exiting the squeeze chute), 3) exit score (dividing cattle according to exit velocity into q...
متن کاملPhysiological responses of Bos taurus and Bos indicus cattle to prolonged, continuous heat and humidity.
Two experiments were conducted to investigate the physiological responses of Bos taurus (Angus cross, n = 6) and Bos indicus (Brahman, n = 6) cattle to prolonged heat and humidity, as can occur during live export by sea. Each experiment was carried out in climate-controlled rooms, where heifers were exposed to 15 d of sustained heat and humidity. The treatment was designed to be representative ...
متن کاملBos indicus-cross feedlot cattle with excitable temperaments have tougher meat and a higher incidence of borderline dark cutters.
Temperament ratings based on a numerical scale (chute score) were assessed during weighing and handling of cattle at a feedlot. Breeds studied included Braford, Red Brangus and Simbrah. Cattle were fed to a constant fat thickness of 9 to 13 mm (target = 11 mm) over the 12th rib as determined by periodic ultrasound measurements. Cattle were slaughtered in a commercial slaughter plant and stunned...
