Performance and morphometric characteristics of Santa Inês sheep and Texel x Santa Inês lambs on pasture, supplemented in a creep feeding system

Résumé

The objective of this study was to evaluate the performance characteristics of the morphometric sheep of the Santa Inês breed, recently-Paris, with their respective Lamb Texel x Santa Inês, a paste, in creep feeding system. For this purpose, 30 Sheeps and theirs and the respective lamb were used for natural breastfeeding for 60 days until weaning. The randomized blocks used, with two Treatments (absence of the presence of the private feeder), with 10 repetitions, being shadow sheep by repetition municipality or relative lamb. In Studies on the termination of two Cordeiro, the bone of heavy animals was measured at the beginning and at the end of the experiments (25 days), using the 30-Cordeiro weaned. The randomized blocks, used with three Treatments (0.400 of 800 g of concentrate / lamb / DIA). There was no difference in weight between the sheep outside of Cordeiro (supplemented or not). There were no two treatments effect on the morphometric characteristics among the sheep outside between the Lamb bone. The use of creep feeding did not provide greater weight gain in recovery to give weight to give infant sheep, nor did it provide greater weight gain, we Lamb supplemented in relation to this not supplemented during breastfeeding, but the supplementary feed 400g / animal / day in the finishing phase it shows better results for I gained two lambs of weight.
