Maternal and reproductive performance of Brahman × Angus, Senepol × Angus, and Tuli × Angus cows in the subtropics

چکیده
To determine the maternal and reproductive performance of F1 cows in the subtropics, 42 Brahman × Angus, 34 Senepol × Angus, and 50 Tuli × Angus cows were bred to Angus bulls to calve first and subsequently bred to Charolais bulls to calve as 3to 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 × Angus than either Brahman × Angus or Tuli × Angus cows. Weaning weights of Angus-sired calves were heavier (P < 0.01) from Brahman × Angus (213.5 kg) than either Senepol × Angus (194.9 kg) or Tuli × Angus (191.5 kg) cows. As 3to 8yr-old cows, calf birth weights were heavier (P < 0.05) from Senepol ×Angus compared with Brahman ×Angus but not Tuli × Angus cows. Weaning weights of Charolais-sired calves were heaviest (P < 0.05) from Brahman × Angus cows (268.9 kg), lightest from Tuli × Angus cows (233.4 kg), and intermediate from Senepol ×Angus cows (245.0 kg). Calf crop born and calf crop weaned

متن کاملOvarian and endocrine characteristics during an estrous cycle in Angus, Brahman, and Senepol cows in a subtropical environment.
To determine breed differences in ovarian function and endocrine secretion, daily rectal ultrasonography was conducted on multiparous lactating Angus (temperate Bos taurus; n = 12), Brahman (tropical Bos indicus; n = 12), and Senepol (tropical Bos taurus; n = 12) cows during an estrous cycle in summer. Blood was collected daily to quantify plasma concentrations of FSH, LH, progesterone, estradi...
متن کاملGrowth curves of crossbred cows sired by Hereford, Angus, Belgian Blue, Brahman, Boran, and Tuli bulls, and the fraction of mature body weight and height at puberty.
The objective of this study was to evaluate the growth curves of females to determine if mature size and relative rates of maturation among breeds differed. Body weight and hip height data were fitted to the nonlinear function BW = f(age) = A - Be(k×age), where A is an estimate of mature BW and k determines the rate that BW or height moves from B to A. Cows represented progeny from 28 Hereford,...
متن کاملGenetic divergence in cellular resistance to heat shock in cattle: differences between breeds developed in temperate versus hot climates in responses of preimplantation embryos, reproductive tract tissues and lymphocytes to increased culture temperatures.
The detrimental effects of heat stress on fertility in cattle are less pronounced in heat-tolerant breeds. Although these genetic differences reflect differences in thermoregulation, cells from heat-tolerant breeds are less adversely compromised by increased temperature (that is, heat shock) than cells from heat-sensitive breeds. Experiments were performed to test the hypothesis that cells and ...
متن کاملImmunosuppressive effect of uterine secretory protein from Angus and Brahman cows upon lymphocytes in vitro.
Uterine luminal protein collected on d 17 (estrus = d 0) from Angus (n = 20) and Brahman (n = 19) cows of varying reproductive status was evaluated for immunosuppressive activity in vitro. Reproductive status consisted of the following categories: nonpregnant (uterine flushing was devoid of embryonic material); remnant (uterine flushing contained obvious degenerative fragments of embryonic tiss...
