Efeitos do tipo de ração inicial sobre a morfologia intestinal e digestibiliade dos nutrientes em leitões

Thirty piglets, weaned at an average age of 28 days, were used in experiment one. After weaning, 24 animals were transferred to the nursery in groups of two to each pen and fed simple or semi-complex diets ad libitum. On weaning day (day 0), six pigs were slaughtered. On days 7 and 21 post-weaning, one animal from each nursery pen was slaughtered to study mucosal thickness (MTD and MTJ) and villi heights (VHD and VHJ) in the duodenum and jejunum. The average values observed for MTD, VHD, MTJ, and VHJ were not influenced by type of diet. MTD, MTJ, and VHJ increased from days 7 to 21 post-weaning. Polynomial regression spanning days 0, 7, and 21 showed a linear effect for MTJ and a quadratic effect for VHD and VHJ. In experiment two, 16 piglets weaned at an average age of 28 days were used in two metabolic trials carried out during two periods of the initial phase (days 5 to 14 and days 19 to 28 postweaning), to determine the nutritional value of simple and semi-complex diets. There were no differences among treatments in apparent digestibility of crude protein and dry matter and the values for digestible or metabolizable energy of the diets. It was concluded that composition of the starter diet did not influence the intestinal morphology of piglets, the digestibilities of dry matter and crude protein, or the digestible and metabolizable energy contents of the diets.

Genotype by environment interaction in different birth seasons for weight at 240, 365 and 450 days of age in Tabapuã cattle

The objective of this study was to evaluate the effect of genotype by environment interaction (GEI) on the weight of Tabapuã cattle at 240 (W240), 365 (W365) and 450 (W450) days of age. In total, 35,732 records of 8,458 Tabapuã animalswhich were born in the state of Bahia, Brazil, from 1975 to 2001, from 167 sires and 3,707 dams, were used. Two birth seasons were tested as for the environment effect: the dry (D) and rainy (R) ones. The covariance components were obtainedby a multiple-trait analysis using Bayesian inference, in which each trait was considered as being different in each season. Covariance components were estimated by software gibbs2f90. As for W240, the model was comprised of contemporary groups and cow age (in classes) as fixed effects; animal and maternal genetic additive, maternal permanent environmental and residual were considered as random effects. Concerning W365 and W450, the model included only the contemporary aged cow groups as fixed effects and the genetic additive and residual effects of the animal as the random ones. The GEI was assessed considering the genetic correlation, in which values below 0.80 indicated the presence of GEI. Regarding W365 and W450, the GEI was found in both seasons. As for post-weaning weight (W240), the effect of such interaction was not observed. ©2012 Sociedade Brasileira de Zootecnia.
