Effect of Berchemia discolor Leaf Meal (Muni Tree) on Feed Intake, Growth Performance and Digestibility of Non-Descript Goats.
Seasonal feed shortages often limit goat productivity in rural areas, creating a need for alternative, locally available feed resources. This study evaluated the effect of Berchemia discolor leaf meal on feed intake, digestibility and growth performance of South African non-descript goats. Sixteen yearling goats (average age 12 months, body weight 19.63 ± 1.68 kg) were randomly assigned to four dietary treatments in a completely randomized design and housed individually in metabolic cages. They were fed diets containing 0%, 15%, 20% and 30% B. discolor leaf meal, formulated on a dry matter basis for 42 days (14-day adaptation, 28-day measurement). B. discolor supplementation had no effect on weight and feed intake (p > 0.05). However, goats fed diets with 0% and 30% inclusion levels had a significantly higher average daily gain and more efficient feed conversion ratio compared to those fed 15% and 20% inclusion levels (p < 0.05). Daily dry matter intake did not differ (p > 0.05) among groups. However, B. discolor had lower (p < 0.05) crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents compared to the control (0% inclusion). Metabolic weight intakes were similar (p > 0.05) across treatments. B. discolor had no effect (p > 0.05) on dry matter digestibility, but CP and ADF digestibility were higher (p < 0.05) in goats fed 0% B. discolor than those in 15%, 20% or 30% inclusion groups. In conclusion, B. discolor inclusion improved growth performance and feed conversion efficiency in non-descript goats, though higher levels reduced nutrient digestibility. Inclusion up to 20% supported intake and growth, but the highest feed conversion ratio was observed at 0% and 30% inclusion.

期刊介绍:
Animals (ISSN 2076-2615) is an international and interdisciplinary scholarly open access journal. It publishes original research articles, reviews, communications, and short notes that are relevant to any field of study that involves animals, including zoology, ethnozoology, animal science, animal ethics and animal welfare. However, preference will be given to those articles that provide an understanding of animals within a larger context (i.e., the animals'' interactions with the outside world, including humans). There is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental details and/or method of study, must be provided for research articles. Articles submitted that involve subjecting animals to unnecessary pain or suffering will not be accepted, and all articles must be submitted with the necessary ethical approval (please refer to the Ethical Guidelines for more information).
