SUPLEMENTASI KONSENTRAT PADA PAKAN DAUN GAMAL TERHADAP KINERJA REPRODUKSI KAMBING LOKAL PERIODE POSTPARTUM

Abstract

Glyricidia sp. is a  considerable potential legumimous tree as a source of  goat feed. The leaves contain a  high protein, and expected to improve the reproductivity of livestock. This study examined the effect of Glyricidia leaves concentrat supplementation on local goat reproduction  in postpartum period.  Twelve 2 to 3 years old female local goats with average initial body weight of 23,08 ± 1,68 kg were used in this study.  The animal were placed randomly for  feeding, and  four replicate treatments were applied:  R₀ = Concentrate 0% BW + Glyricidia spad-libitum; R₁ = Concentrate 0.5% BW + Glyricidia sp ad-libitum; R₂ =  Concentrate 1.0% BW + Glyricidia sp ad- libitum. The variables measured were dry matter intake (DMI), average daily gain (ADG), length of estrous, and pregnancy rate. The data of DMI, ADG, and length of estrous were analyzed using Completely Randomized Design (CRD) one way classification. If  significant differences among treatments occured, the Least Significant Difference (LSD) test was performed. The difference in pregnancy rate were analyzed using Chi-square. The results showed that the dry matter intake, average daily gain, length of estrous and pregnancy rate to female goats were significantly higher in concentrate supplementation of  0.5%  and 1.0% BW than without  concentrate supplementation. On the other hand,  between concentrate supplementation of 0.5% and 1.0% BW did not differ significantly.
