Title: Use of Molasses-Based Rations for Lactating Sudanese Nubian Goat
Author: Dawoud, Ahmed Gamal Ahmed
Abstract: This feeding trial was conducted to study the effect of replacement of sorghum by molasses in conventional ruminant rations, on lactational performance and milk composition of Sudanese Nubian goat (SNG). Eighteen healthy freshly kidding lactating SNG were selected from the flock at the Central Livestock Research Station, Kuku. They were allotted randomly into two experimental groups (9 heads each), designated as control and test groups on the basis of similar live weight. Each group was further divided into three subgroups (3 heads each) according to the date of kidding. Two iso-caloric and iso-nitrogenous complete diets were formulated using different feed sources. The test diet was molasses-based and the control was a sorghum-based diet. Dry matter intake (DMl) was estimated for each subgroup. The experiment continued for 20 weeks during which daily milk yield, DMI, monthly milk composition and monthly live weight changes were monitored. No significant (P > 0.05) difference was recorded in all parameters under investigation. Nevertheless, the test group (molasses fed) had recorded an 8% increase of 4% fat corrected milk (FCM) compared to the control group. The higher 4% FCM yield by the molasses-fed group was attributed to the high adipose tissue mobilization. Thus application of a high molasses-based feeding system for milk production requires basic nutritional additives to improve its utilization, namely, undegradable fat and starch. A wide variation in milk production was noted for SNG in this study which is indicative of the great variation in the genetic makeup of the breed. Therefore, milk production potential of the breed is believed to be higher than commonly known, and through selection coupled with improved management a productive SNG can be obtained.
