Nutrient composition and ruminal degradability of arachis glabata using nylon bag technique in dairy cattle

Abstract

Arachis glabata is new variety forage which tolerates drought and provide high protein.This kind of plant is suitable as dairy cow diet. The research was divided into 2 experiments, Experiment 1 was conducted to study on nutritive value of Arachis glabata.The experimental design was Randomized Completely Block Design (RCBD) experiment with three treatments. Each treatment consisted of three blocks (three crops) and followed different three variety of Arachis glabata as Cv. Florigraze, Cv. Arbook and Cv. Ecotart. Results showed that three variety of Arachis glabata were 28.26-30.75 % of dry matter (P>0.05). In addition, Arachis glabata Cv. Arbook was grater 19.78 % of protein than other group of Arachis glabata (P<0.01). Furthermore, Arachis glabata Cv. Florigraze was grater 17.63 of hemicelluloses and 3,830.00 kcal/kg of gross energy significant different among other group of Arachis glabata (P<0.05). Experiment 2 was conducted to study on ruminal degradability of Arachis glabata using In situ technique in dairy cattle. The experimental design was Randomized Completely Block Design (RCBD) experiment with three treatments. Each treatment consisted of three blocks (three ruminally fistulated dairy cattle) and followed different three variety of Arachis glabata as Cv. Florigraze, Cv. Arbook and Cv. Ecotart. Results showed that Arachis glabata Cv. Florigraze and Arachis glabata Cv. Arbook was grater dry matter, organic, matter and protein degradability at 0-4 hour and 24-28 hour than Arachis glabata Cv Ecotart (P<0.05). In addition, kinetic of degradation (a, b, c, and p) of dry matter, organic, matter and protein were not significant different (P>0.05) among three variety of Arachis glabata.
