Abstract
To increase the quality of dry rice straw and meet the needs of nutritional requirement for livestock, availability and technology should be considered to come up with an improve that is easy and inexpensive feeding material. The research aims to find out the effects of the combination of rice by-products (dry fermented straw and bran) with legumes (Leucaena and Gliricidia leaves) in increasing the growth of Bali cattle. This research was conducted at the Maliana Administrative, Bobonaro Municipality, from August 28, 2019 to November 17, 2019. In this research, five (5) male and growing beef cattle were used. This research method used the experimental method with Latin Square Design consisting of five treatments and five replications. The feed combinations or treatments used for beef cattle ration formulations, were: T1 is composed of 40% fermented rice straw, 20% rice bran, 10% Gliricidia and 30% Leucaena; T2 is composed of 55% fermented rice straw, 10% rice bran, 20% Gliricyda and 15% leucaena; T3 is composed of 50% fermented rice straw, 5% rice bran; 35% Gliricyda, and 15% leucaena; T4 is composed of 45% fermented rice straw, 15% rice, 30% Gliricyda, and 10% leucaena; T5 is composed of 30% fermented rice straw, 25% rice, 5% Gliricyda, and 40% leucaena. The variables observed were feed intake (kg), feed conversion and animal body weight (kg). Data analysis show that no significant effect (P> 0.05) on ration consumption but had a significant effect (P<0.05) on body weight gain and feed conversion of all experimental beef cattle used in the study. The result of comparison of mean show that the treatment T3 can accelerate growth and improve feed conversion of male beef cattle in their growth phase.
Highlights
Beef cattle is a ruminant livestock that has great potential to produce high quality meat to meet human consumption needs, especially for the protein
The feed combinations used for beef cattle ration formulations, were: T1 is composed of 40% fermented rice straw (FRS), 20% rice bran (RB), 10% Gliricidia (GL) and 30% Leucaena (LL); T2 is composed of 55% FRS, 10% RB, 20% GL and 15% LL; T3 is composed of 50% FRS, 5% RB; 35% GL, and 15% LL; T4 is composed of 45% FRS, 15% RB, 30% GL, and 10% LL; T5 is composed of 30% FRS, 25% RB, 5% GL, and 40% LL
The result of mean comparisons revealed that the T3 is the best treatment to feed beef cattle, especially in terms of body weight gain and feed conversion rate
Summary
Beef cattle is a ruminant livestock that has great potential to produce high quality meat to meet human consumption needs, especially for the protein. Each household keeps four to five heads of cattle as their secondary farming activity. In other parts of the country, there is a need to develop the potential of beef cattle starting from the improvement of local feed utilization. Availability and potential of indigenous feed resources can help manage the need for livestock feeds. Three important factors have to be considered namely, quantity and quality of feeds, and management. Among these production activities, quality and quantity of feeds are very critical due to the huge expenditure
