Comportamento ingestivo e desempenho de cabras suplementadas com óleo de linhaça

Abstract

Goat farming is a worldwide activity. Brazil is in 22nd position in the world ranking in relation to goat breeding, about 8,851,879 animals. In this context, the objective was to evaluate the ingestive behavior and productive performance of lactating goats submitted to diets containing different levels of flaxseed oil. The experiment was carried out at the Caprine and Ovine Culture Laboratory of the Center for Human, Social and Agrarian Sciences, belonging to the Federal University of Paraíba, located in the municipality of Bananeiras, Paraíba State, Brejo Paraibano microregion. Ten multiparous Saanen goats weighing 40 ± 6 kg and 30 ± 5 days of lactation were used. The ingredients used were Tifton hay, ground corn grain, soybean meal, vitamin / mineral supplement, urea, and flaxseed oil levels (0, 1, 2, and 3%) to replace corn in the diets. No significant effect was observed due to the different levels of flaxseed oil in the diet of dairy goats for feeding, rumination and idle times. No significant differences were observed for milk yield data as a function of different levels of flaxseed oil in the diet of dairy goats. The inclusion of flaxseed oil in goat feed up to 3% can be recommended without impairing milk production and animal weight, however it is necessary to verify the economic viability.
