Introduction of Setaria Grass and Gliricidia Legume as Feed in Relation to Increasing of Ruininant Animal Productivity at Serang River Basin

Abstract

This experiment was conducted for three months, to studies the influence of setaria and glyricidia forages of feeding in combination with mineral supplementation on nutritional status and performance of goats at Serang River Basin. Twenty four male yearling indigenous goat with avarage body weight 14,01 + 0,6 kg from the upland area at Scrang River Basin, were used as experimental material. The forages were obtained from around of experimental location. There were two treatment factors in this investigation. The first factor was : forages feeding (T0 100 % conventional forage; T170 % conventional forage + 30 Sctaria grass; T2
40 % conventional forage + 30 Setaria grass + 30 % Glyricidia legume; and T3 20% conventional forage + 30 % Setaria grass + 50 % Glyricidia legume), wheareas the second factor was : mineral supplementation (S0 : without mineral supple-mentation; S1 1 with mineral supplementation). Several measured variables, included ; drymatter and total digestible nutrient consumption; in viva drymatter and organic matter digestibility; the rumen volatile fatty acid, ammonia and total protein production; calcium and phosphonis concentration in feed, blood serum and faeces; daily body weight gain. The collected data were statistically analized by analysis of variance with 4 x 2 x 3 factorial treamcnt pattern in randomized completelly block design (RCBD). The result of this investigation showed that dry matter forages consumption in T2 and T3 treatment groups were higher than above variables in Tt) and T1 treatment groups (namely: 301.1 and 328.9 vs 219 and 241.7 g/head/day respectivelly). The in viva dry matter and organic matter digestibility of forages in T2 and T3 treatment groups were higher (P<(),05) than those in T1 treatment groups, but non significantly differents from T0 treatment group. The average daily body weight gain of animals in T0, T2 and T3 treatment groups were higher (P < 0,05) than Tl treatment group (namely: 68.24; 69.11 and 69.21 vs 68.24 g/head/day). Average daily body weight gain of experimental goats without mineral supplementation (S0), namely 7 35.06 g/head/day, whearcas for experimental goat with mineral supplementation (S1) was 36.77 g/head/day.
