Studies were conducted to assess nutritional value of pearl millet grain (Pennisetum glaucum [L] R. Br.) for lactating and growing goats. Three complete diets containing either 40% corn, 40% pearl millet, or 40% corn and pearl millet mixed 1:1 (wt/wt) were balanced to contain 16% crude protein and 2.24 Mcal DE/kg on an air-dry basis. Forty-five does were blocked by kidding date and randomly assigned to diets for a 7-wk investigation. Feed intake and milk production were unaffected (P > .25) by treatment, and they averaged 2.86 and 2.47 kg daily, respectively. Thirty-three growing goats were blocked by sex and fed the same diets for 15 wk. Daily growth rate and feed to gain ratio were depressed (P < .05) by 25.4 and 19.0%, respectively, when corn was completely replaced with pearl millet. Digestion coefficients for DM, GE, CP, and NDF were reduced by over 10 percentage units with partial or complete replacement of corn by pearl millet. Ruminal acetate and ratio of acetate to propionate increased (P < .05) but butyrate, propionate, and ammonia were depressed (P < .05) with the pearl millet diets. Growing goats consumed 43 meals daily. They consumed 26.9, 32.6, 27.4, and 13.1% of their ration during the morning (0600 to 1200), afternoon (1200 to 1800), evening (1800 to 2400), and night (2400 to 0600), respectively. Pearl millet is a useful energy feed for mature, but not for growing, goats.
