Efeito da vermifugação sobre os constituintes corporais de ovinos em pastejo na caatinga suplementados com blocos multinutricionais.

Abstract

The Brazilian sheep industry is a promising activity economically and socially, thus contributing to improving the lives of producers, as well as being a good way to establish a healthy diet and quality. This study was developed in Lameirão farm Health Center and Rural Technology (CSTR) at the Federal University of Campina Grande (UFCG), geographically located at coordinates 7º02'58.3 "S 37 ° 29'32.5" W, in Santa Teresa , Paraiba, Brazil, in November and December 2013 and January 2014. It was used 24 sheep (½ + ½ Santa Inês Dorper) intact males with an average age of 6 months, average weight of 24.60 ± 0.91. Initially identified and divided into four treatments comprised 6 animals. The experimental design was completely randomized (DIC), with 4 treatments and 6 repetitions. The results were submitted to analysis of variance using the SAS program (2003) and the mean values were compared by Tukey test at 5% and probability. There were no statistical differences (P> 0.05) as the biometric variables of sheep supplemented with multinutrient blocks incorporated with purging potato semiextensivo system in the bush. The morphometric analysis the perimeter of the croup was higher for the animals supplemented with multinutrient blocks containing the purge potato and chemical dewormer, and lower for the animals supplemented with multinutrient blocks without the addition of purge potato. Towards non carcass components (edible part) of Santa Ines sheep supplemented with multinutrient blocks in semiextensivo regime in the bush it is observed that there were statistical differences in the percentage of full and spleen gastrointestinal tract (Table 3) as well as the weight absolute (kg) Liver (P <0.05). Towards non carcass components (part inedible) there was no significant difference (P> 0.05) for these variables between the different levels of purge potato incorporated into multinutrient blocks offered to sheep. Overall, the constituents not studied the carcass obtained significant values for the species and for handling the situation were submitted.
