可可豆荚壳（CPH）含粗蛋白76.6克/千克干物质、粗纤维325克/千克干物质、粗脂肪43.7克/千克干物质、粗纤维101克/千克干物质、酸性洗涤纤维414克/千克干物质、中性洗涤纤维522克/千克干物质和半纤维素108克/千克干物质。 代谢能含量为4.72 MJ kg-1。 与玉米相比，CPH含有较少的氨基酸，除了赖氨酸。 在饲养试验中，以玉米和鱼粉为主要成分的5种饲料（分别含0、50、100、150和200 g CPH kg-1），自由采食450只1周龄肉仔鸡（AF Bosbek系）7周。 鸟类可以自由饮水。 与对照组相比，添加不同水平的CPH肉鸡日粮使最高水平的包含物的采食量增加了近60%（r = 0.97），降低了生长（r = -0.85），因此降低了食物利用效率（r = 0.96）。 可可壳喂养的鸟类消耗更多的水，随着CPH的每一次增加，消耗的水有增加的趋势（r = 0.99）。 饲料中CPH浓度与屠宰率呈高度负相关（r = -0.85）。 饮食中没有可归因于CPH的死亡。
Cocoa pod husk (CPH) contained (g kg-1 dry matter) 76.6 crude protein, 43.7 ether extract, 325 crude fibre, 101 ash, 414 acid detergent fibre, 522 neutral detergent fibre and 108 hemicellulose. The metabolizable energy content was 4.72 MJ kg-1. In comparison with maize, CPH contained less amino acids, except lysine. In a feeding trial, five diets containing 0, 50, 100, 150 and 200 g CPH kg-1, with maize and fishmeal as major ingredients, were given ad libitum to 450 1-week-old broiler chicks (AF Bosbek strain) for 7 weeks. Birds had free access to water. Addition of graded levels of CPH broiler diets increased food intake by nearly 60% for the highest level of inclusion (r = 0.97), reduced growth (r = -0.85) and hence reduced efficiency of food utilization compared with the control (r = 0.96). Cocoa husk-fed birds consumed more water with a trend toward increased water consumption with each increment of CPH (r = 0.99). High negative correlation (r = -0.85) was observed between the concentration of CPH in the diet and carcass dressing percentage. There were no deaths attributable to CPH in the diet.
