Consumption, nutrient digestibility and nitrogen retention in pe goats received ransum with various levels of gamal (gliricidiasepium) balance versus concentrate

Abstract

The research aims to determine the consumption, nutrient digestibility and nitrogen retention in PE goats, which has been carried out in Sidemen Village, Karangasem, Bali and in the Lab. Animal Nutrition and Feed at Udayana University. The research design used was the Latin Square Design (LSD) with treatment consisting of (P1) 55% field grass with 45% concentrate; (P2) 55% field grass with 15% Gamal and 30% concentrate; (P3) 55% field grass with 30% Gamal and 15% concentrate; (P4) 55% field grass with 45% Gamal. Research variables include consumption, nutrient digestibility and nitrogen retention. The results showed the consumption of dry matter and crude protein between treatments was not significantly different (P> 0.05). Crude fiber consumption of P4 treatment was significantly (P <0.05) higher than P1, but P4 was not significant (P> 0.05) higher than P2 and P3. The dry matter digestibility coefficient and crude fiber digestibility coefficient between treatments were statistically significantly different (P> 0.05). The digestibility coefficient of organic matter, crude protein digestion coefficient and nitrogen retention in the P1 treatment were not significantly (P> 0.05) higher than P2, but P1 was significantly (P <0.05) higher than P3 and P4. The conclusion of this study is that the feeding of P2 treatment with a balance of 30% concentrate and 15% Gamal in the grass-based field feed is very efficient to increase consumption, nutrient digestibility and nitrogen retention in PE goats.
