Food supplementation of Anglo-nubian goats in rainy season in semi-arid region of Northeast Brazil

Abstract

This experiment was carried out to evaluate the influence of food supplementation on milk production of Anglo-nubian goats, during the rainy season, in semi-arid region of Northeast Brazil. Twenty four goats were maintained in lowered "caatinga", distributed randomly according to the parturition order and milk production in three supplementation levels: N₀ - no supplementation, N₁ - 150 g of concentrate/animal/day and N₂ - 300 g of concentrate/animal/day. There was no significant difference (p > 0.05) between supplementation levels. Milk production was described by multiple regression to lactation period, in week. The results showed that the best option to produce milk with Anglo-nubian, during the wet season, is 300 g of concentrate/animal/day.
