Meat production in the dry tropics of Tamaulipas, Mexico: crossbreeding of Bos taurus and Bos indicus
The objective of this study was evaluated the productive performance in Charolais (CH), Simmental (SM) and Braunvieh (BR) sires and Zebu, (ZE), Suiss (SU) x ZE and CH x ZE dams, among birth and weaning calves weights. The environment is dry tropical with summer rains. The livestock grassing in a introducing grasses Star grass (Cynodon nlemfuensis) y Guinea (Panicum maximun). The reproduction was artificial insemination with CH, SM and BR semen and natural insemination with CH sires after insemination. The calves were identificated at birth with the mother number and were weighted in the first 24 ours. The data were analyzed with minimum squares method to determinate, season (SE), calf sex (SX) and dam age (DE). The average for birth weight (BW) was 34.6 kg and only the SE were statistical significant (P < 0.05) for this characteristic. For weaning weight (WW) the mean was 165.7 kg and SE and DE and were statistical significant (P < 0.05). The conclusion is that the environmental effects in this study was more important than genetics effects both BW and WW variables.
