Comportamento ingestivo de ovinos da raça Morada Nova em crescimento recebendo dieta com macarrão instantâneo em substituição ao milho

Abstract

The aim of this study was to evaluate the ingestive behavior of growing Morada Nova sheep, fed different levels of instant noodle residue in substitution for corn. The experiment was conducted at the Agronomic Institute of Pernambuco in the city of Sertânia-PE and 15 male animals were used, divided into five treatments, with them being 0%, 25%, 50%, 75% and 100% of instant noodles. Each ration was duly balanced so that it will meet all the requirements of this category, having a roughage:concentrate ratio of 50:50. Two behavioral observations were made, which took place during 24 hours a day, from 06:00 am to 05:50 the next day. The first, performed after the adaptation period and the second, 28 days later. The animals were housed in individual pens in a completely randomized design with identification. The variables observed were: feeding time, rumination time and leisure time. In addition to the behavior, the frequency in which the animal ingested mineral salt and water was also observed. After the experimental period, the data were tabulated and submitted to analysis of variance and the averages compared by the Tukey test at 5% probability, using the Statistical Analysis Systems softwere (SAS, 2000). There was no significant effect (P> 0.05) for any parameter of ingestive behavior, as well as for the frequency of water consumption. However, there was a significant effect (P <0.05) for the frequency of salt consumption. The residue of instant noodles can be offered in the diet of sheep because it does not change the behavior
