Abstract

This study aims to determine the intake of nitrogen free extract (NFE), crude fiber (CF), and extract eter (EE) of male Kacang goats in the realimentation phase after experiencing different levels of feed restriction. This study used the experimental method Completely Randomized Design (CRD) which consisted of 3 treatments and 5 replications that is T0 livestock without feed restrictions, T1: livestock are limited to 100% of basic life, T2: livestock are limited to 50% of basic life. Variables observed included NFE, crude fiber, and crude fat intake. The results showed that the NFE, CF and EE of male kacang goats in the realimentation phase of the 3 group were not different/ or significant (P > 0.05). The intake of NFE each treatment is a T0 treatment 222,63±18,17; T1 210,12±29,79, and T2 186,72±34,89. The intake of CF (g/e/h) in treatment T0 56,32±2,47; T1 51,94±9,20; and T2 was 49,82±8,79. The intake of EE (g/e/h) in treatment T0 treatment of 10,19±1,10; T1 9,68±1,37; and T2 8,41±1,64. It can be concluded that the intake of NFE, CF and EE in the realimentation phase of livestock restricted feed 100% according to basic life and 50% below the main life is not much different from the Kacang goats which are given normal feed according to their needs.

Abstract

This study aims to determine the nitrogen intake and excretion status of male Kacang goats that receive feed with different energy levels. The study was conducted for three months in the livestock experimental pen of the Faculty of Agriculture, Science and Health, University of Timor Kefamenanu, North Central Timor Regency. Nine male Kacang goats with an initial body weight of 11 to 13 kg and aged between 6 and 12 months were divided into three groups, each group representing a different treatment. The treatments were: T1 = livestock obtained an energy level of 65%, + CP 15%, T2 = livestock obtained an energy level of 67%, + CP 15%, and T3 = livestock obtained an energy level of 70%, + CP 15%.The variables measured consisted of nitrogen consumption, fecal nitrogen and urine nitrogen. The results of the study showed that the highest nitrogen consumption in the T3 treatment was 3.2033 ± 0.1549 g/head/day, followed by the T2 treatment of 3.0894 ± 0.0384 g/head/day, and the T1 treatment of 2.6159 ± 0.0658 g/head/day; fecal nitrogen in the T1 treatment was 1.5070 ± 0.3880 g/head/day, followed by the T3 treatment of 1.1673 ± 0.2751 g/head/day, and the T2 treatment of 1.1566 ± 0.5887 g/head/day; urinary nitrogen in the T2 treatment was 0.7906 ± 0.1804 g/head/day, followed by the T1 treatment of 0.7606 ± 0.0456 g/head/day and the T3 treatment of 0.6933 ± 0.0637 g/head/day.   The results of the analysis of variance showed that the treatment had a significant effect on nitrogen consumption and had no significant effect on fecal nitrogen and urinary nitrogen. It was concluded that feeding with different energy levels could increase nitrogen intake but relatively the same fecal and urinary nitrogen excretion.

Abstract

Joper chickens are breeds of kampung chickens, Bangkok chickens, or other local breeds of chickens separated from purebred chickens. In addition to genetic factors and feed management, the use of natural constituents as feed additives can affect the meat quality of super hens. Feed additives are ingredients that do not include food substances that are added to the stove in small amounts and are aimed at spurring growth and increasing feed efficiency. The existence of various studies in the selection of feed raw materials that produce quality feed additives that are easy to use and cheap to meet the needs of super rural chickens are moringa leaves. The design used in this research was a Completely Randomized Design (CRD) with 4 treatments and 5 replications. The treatment consisted of T0 (Ration does not contain Moringa leaf flour), T1 (Ration contains 6% Moringa leaf flour), T2 (Ration contains 9% Moringa leaf flour), T3 (Ration contains 12% Moringa leaf flour), The parameters observed were feed consumption, body weight gain and feed conversion. The results showed that Moringa leaf flour had a significant effect on feed consumption, body weight gain and feed conversion. The best results were obtained in treatment T1, namely the ratio containing 6% Moringa leaf flour, which was able to increase feed consumption by 367.46 grams, body weight gain by 88.62 grams and feed conversion ratio by 4.16.
