Intensive rearing of goats for meat, using rations consisting essentially of local ingredients
Jamaica's foreign exchange position militates against continued heavy feed importation of goat meat and ingredients traditionally used in animal feed formulation. This study was part of a program aimed at developing cattle feed from local ingredients. Goats were reared intensively using such locally developed diets. A randomized complete block design was used. Twenty-four animals balanced for sex were used in the trial. The six treatments were 5 concentrate rations fed under housed conditions and pasture. The rations were control (commercial, corn-soybean based), and 4 others consisting of varying amounts Cassava Meal, Quickstick Meal (Glyricidia sepium), Grass Meal, Ricebran Molasses, in some cases fortified with NPN or SBM. Local ingredients constituted up to 75 percent of total composition. Highest average daily gain (ADG) occured on the control ration of 120.8 g, followed by one locally developed ration, 115.3 g. Feed conversion (kg feed/kg gain) were respectively 6.73 and 7.22. Lowest ADG was obtained on range, 53.6 g. Overall ADGs were for the various rations: control 120.8 g, locally developed 115.3 g, 104 g, 8.9 g, 77.2 g. Corresponding feed conversions were: 6.73, 7.22, 8.47, 8.16 and 11.23, respectively. Females on the two best rations had better feed conversions compared to males: 6.53, 6.53 vs 6.92 and 7.71. In ADG males did better: 129.8 a d 134.4 g vs 112.6 g and 96.7 g. Animals under intensive system performed better in terms of ADG and carcass quality than those under prevailing range conditions. Indications are that chosen local ingredients have potential in a viable local feed industry
