title: Almond hulls in diets for lactating goats: effects on yield and composition of milk, feed intake, and digestibility.
abstract: Four cubed rations of similar chemical composition were fed ad libitum to 16 lactating yearling Alpine goats. The rations contained 0, 15, 25, and 35% almond hulls; 0, .5, 1, and 1% urea; and 58.4, 42.5, 32.0, and 22.0% alfalfa hay (DM basis). Chromic oxide was added as a digestibility marker. Average nutrient composition of diets was 91% DM, 20% CP, 32% NDF, 9% ash, and 4.39 Mcal gross energy/kg. Goats were randomly assigned to one of four diet orders in four replications of a 4 X 4 Latin square, blocked by goat and period. Data were collected in the 3rd wk of each period. Diets containing 25 and 35% almond hulls increased DM intake and reduced milk protein percent and digestibilities of DM, organic matter, ash, and NDF. Dry matter intake and weight gain were highest for the diet containing 35% almond hulls and 1% urea. Results indicate that almond hulls and urea can be fed to lactating goats up to these amounts without adversely affecting lactation.
