Effects of different levels of sugar beet roots based concentrates on the performance of Tagger male kids
Abstract
High meat demand in the Sudan enhanced improvement of goat meat production. Tagger is a promising meat breed due to good conformation and high meat quality. Nutrition is a main constraint for goat meat production. Sugar beet is introduced into the Gezira State with no information on effects of dried sugar beet roots (DSBR) based concentrates level on Tagger kids performance, carcass characteristics and meat composition. Twelve Tagger males of 6 months old were housed in individual pens, divided into 3 groups, each with 4 animals and allocated at random to the experimental diets. They were weighed weekly for 8 weeks with a two weeks preliminary period. They were fed groundnut haulm (GNH) ad lib. in two equal meals at 8.0 am and 4.0 pm and refusals were collected and weighed daily. The animals were fed different levels of DSBR based concentrates: 0 (control), 150g and 300g, in two equal parts before GNH meals. The concentrates contained 68% DSBR,15% groundnut cakes, 15% sunflower cakes, 1% salt and 1% oyster shell. Samples of feeds and refusals were stored for laboratory analysis. Resultd showed that groundnut haulm (30% CP, 8.8% CF, 4.8% ash and 48.2% NFE) had better proximate analysis than refusals which generally improved with concentrates levels. Dried sugar beet had 12.9% CP, 11.0% CF and 59.25% NFE and the concentrates had 42.25% CP, 2.0% CF and 49.5% NFE. Overall mean BW generally increased with concentrates level (10.78, 10.9 and 12.19kg at 0, 150 and 300g, respectively), but not significantly different. Overall mean daily feed intakes varied with concentrates level and were 1550.89, 1187.46 and 1545.67g at 0, 150 and 300g concentrates, respectively, and were significantly least in animals fed 150g concentrates. Weekly weight gain generally increased with concentrates level in all weeks and was highest in animals fed 150g concentrates with no significant effects for concentrates level. It was 0.55, 0.68 and 0.60 kg at 0, 150 and 300g concentrates, respectively. It is recommended to use DSBR based concentrates in fattening Tagger kids.
