Desempenho de cabras em lactação alimentadas com diferentes fontes de volumosos

Abstract

The objective of this study was to evaluate the economic viability of dairy goats with different dietary plans in a production system for semi-arid dairy goat. The project will be executed at the Experimental Station Pendência, belonging to the State Agricultural Research Company of Paraíba (EMEPA-PB), located in the municipality of SoledadePB. The bromatological analyzes will be carried out at the Animal Nutrition Laboratory of the Department of Animal Science, Federal University of Paraíba (UFPB), located in the city of Areia-PB. In the test, 8 goats (Anglo Nubian) were used, in a double Latin square 4 X 4 where the experimental treatments will be constituted of different sources of volumoso. The experiment lasted 60 days and was composed of 4 periods of 15 days, of which the first 10 days of each period were used to adapt the animals to the experimental diets and the following 5 days to collect data. The diets were composed of forage palm, sorghum silage and buffel grass hay. The parameters evaluated were: consumption; Composition of goats' milk. There was no significant difference (P> 0.05) between diets for dry matter intake (DM) expressed in the different units and for organic matter (OM) consumption. There was no difference (P> 0.05) in the physicochemical composition of goats' milk as a function of the studied sources. The diets evaluated when provided in consortium obtained better results.
