Application of palm kernel oil meal as an aternalive feed stuff for dairy goats/TLRI
|
To explore the diverse feed resources for dairy goats, palm kernel oil meal (PKM) was fed to growing and milking Saanen and Alpine goats at 0, low, medium or high four levels in diets. A total of 40 head of castrated ram and female goats with BW above 35 kg were assigned into four dietary treatments in the 3-mo feeding trial. Twenty head of lactating goats with daily milk yield above 2 kg were also assigned into four dietary treatment and raised individually in repeated 28-d feeding trials. Meanwhile, rumen digestion was monitored by cannulated dry goats and panel test for goat milk was held at the end of both trials. Nutrition in four diets was formulated similarly. Results indicated that even with the high level of PKM in diet, it did not affect the goat growth performance. Daily gain reached 177, 173, 180 and 165 g, respectively for diets with 0 to high level of PKM. Addition of low to medium amount of PKM in goat diets had tendency to improve the milk fat percentage (8%, P < 0.06) and the 3.5% fat-corrected milk (16%, P < 0.11). Milk yields of four groups were 2.54, 2.97, 2.92 and 2.80 kg, respectively. Diets including PKM would not influence the panel test of goat milk. It was concluded from this experiment that as an alternative feed resource, PKM added in goat diets at a low to medium quantity is feasible. |
