Production of Grade Hereford, Beefmaster x Hereford, and Braford x Hereford Calves in South Florida
INTRODUCTION In any discussion of beef cattle production in a particular environment the matter of climatic adaptability is of prime consideration. Adaptation for beef cattle might be defined as the ability to reproduce, grow and thrive under local environmental conditions. Much has been written about the ability or inability of temperate zone breeds of cattle to adapt to hot, humid, subtropica...
متن کاملMaternal and reproductive performance of Brahman x Angus, Senepol x Angus, and Tuli x Angus cows in the subtropics.
To determine the maternal and reproductive performance of F1 cows in the subtropics, 42 Brahman x Angus, 34 Senepol x Angus, and 50 Tuli x Angus cows were bred to Angus bulls to calve first and subsequently bred to Charolais bulls to calve as 3- to 8-yr-olds. Age at first calving did not differ among crossbred cows. Angus-sired calf birth weights were heavier (P < 0.01) from Senepol x Angus tha...
متن کاملCow-calf and feedlot performances of Brahman-derivative breeds.
A study was conducted to compare Brangus, Beefmaster, Gelbray, and Simbrah breed influences for economically important traits. Brangus (9), Beefmaster (12), Gelbray (10), and Simbrah (7) sires were used in purebred and crossbred (Brahman x Hereford F1 cows) matings to generate calves (326) in eight breed groups. Beefmaster cows were of similar size (448 kg), Brangus and Gelbray cows were 11% he...
متن کاملAn evaluation of tenderness of the longissimus muscle of Angus by Hereford versus Brahman crossbred heifers.
Postmortem aging of carcasses obtained from Angus-Hereford (n = 8) and 5/8 Brahman crossbred (n = 8) heifers was investigated to determine the cause of variation in meat tenderness. Raw longissimus muscle (LM) myofibril fragmentation index was lower and cooked LM Warner-Bratzler shear force was greater for the 5/8 Brahman crossbreds (P less than .05). The activities of calcium-dependent proteas...
متن کاملReproduction and calf performance of Angus-sired and Polled Hereford-sired cows bred to Angus and Brahman bulls for primiparous calving as two- vs three-year-olds.
This 4-yr study was conducted with Angus (A)-sired and Polled Hereford (PH)-sired crossbred heifers that were exposed to either A or medium-frame Brahman (B) bulls from primiparous calvings either as 2- or 3-yr-olds. Each year, heifers were allotted at random within breed composition and age of dam to breeding groups on pasture for an 84-d breeding period that began in late March or early April...
