EFFECT OF USING TEMPE WASTE AS A SUBSTITUTE OF CONCENTRATE AND COMPLETE RUMEN MODIFIER SUPPLEMENTATION ON CONSUMPTION AND DIGESTIBILITY OF DRY INGREDIENTS IN SHEEP FEED

Britania Fitha Tarizareta, Fransisca Maria Suhartati, Munasik Munasik — Mon, 25 Mar 2024 00:00:00 +0000

Complete Rumen Modifier (CRM) is a feed supplement consisting of several components and mixtures that act as defamatory, methanogenesis inhibitors, bacterial growth factors, and triggers for fiber digestion. Feed supplements can be used to stimulate growth, prevent disease and improve the quality of rations. Tempe dregs and rice straws are wastes that can be used as ruminant animal feed, however, both are of low quality and high in crude fiber content. The high crude fiber affects the digestibility and consumption of feed, so it is necessary to treat it to improve the quality of the feed ingredients. Tempe dregs given to livestock are processed by drying beforehand while rice straw is treated chemically, namely by the ammonia method. This study aims to determine the effect of replacing Tempe dregs with concentrate and suplementation of CRM on the consumption and digestibility of dry matter for sheep feed. The material used were 18 rams aged 7-8 months. This research was carried out experimentally with the RAK analysis model as a group, namely the initial weight of sheep after feed adaptation in as many as 6 groups that served as replicates. The feed given to the sheep were concentrate in the control treatment (P1) and tempe dregs (P2 and P3) 2.5% of body weight. The treatments tested were P1: concentrate 2.5% of body weight (based on BK) + ammoniated rice straw (JPA) ad libitum, P2: dregs of tempe 2.5% of body weight (based on BK) + ammoniated rice straw (JPA) ad libitum, P3 : P2 + CRM 1%. The observed variables included consumption and dry matter digestibility of the feed. The results showed that replacing tempe dregs with concentrate and CRM supplementation had a very significant (P<0.01) effect on dry matter consumption and a significant effect (P<0.05) on feed dry matter digestibility. Based on the results of the study, it was shown that tempe dregs could completely replace concentrate because it could increase the consumption and feed dry matter digestibility for sheep feed without the need to add 1% CRM.

The purpose of this study was to examine the effect of Complete Rumen Modifier (CRM) administration on dry matter consumption and digestibility of male Bali cattle feed and to provide a solution to prevent acidosis in cattle. The material used was 3 male Bali cattle aged 24 months with an average body weight of 209 kg. The research design used RBSL 3x3, the treatments tested were P1 (rice straw + 2% concentrate of body weight), P2 (P1 + CRM 0.5% from DM concentrate), and P3 (P1 + CRM 1% from DM concentrate). The variables measured were consumption and digestibility of dry matter (BK), the data obtained was tested using analysis of variance and the Orthogonal Polynomial test. The results of the analysis of variance showed that the treated feed had a significant effect (P<0.05) on consumption and dry matter digestibility (BK). The Orthogonal Polynomial test shows that the higher the administration of CRM up to 1% level, the consumption and digestibility of dry matter increases linearly respectively with the equation y = 4,41x + 63,10 with r²=0,50 dan y = 5,79x + 70,43 with r²=0,84. The conclusion obtained is that the provision of concentrate feed with the addition of CRM up to 1% level can increase consumption and digestibility of BK.

The internship entitled "The Effect of Environmental Conditions in Cages Between Open House Cages and Semi-Closed Houses on the Performance of Broiler Chickens on the Performance of Broiler Chickens at PT BUSS Sukabumi" was held on September 15 2021 to December 25 2021, at PT. Berkat Unggas Sehat Sejahtera, Sukabumi, West Java. The purpose of this internship is to analyze the influence of environmental conditions in the cage between open house and semi closed house cages. The method used in this internship is carrying out broiler maintenance activities with a focus on observing the environmental conditions of the cage and the performance of broiler chickens. The target of the internship is broiler chicken farm at PT. Berkat Unggas Sehat Sejahtera. The material used in open house cages was Cobb strain chickens with a total of 6500 population while for semi closed house cages using Rose strain chickens with a population of 12,103 population. The observation took place at PT. Berkat Unggas Sehat Sejahtera. The variables observed were body weight, body weight gain, mortality, feed conversion ratio (FCR), and IP in chickens kept in open house and semi closed house cages. Performance in the open house cage in the fourth week resulted in a body weight of 1530 g with a PBB of 573 g with a mortality rate of 4.75%, then the FCR obtained was 1.48, and the IP was 350. Performance in the semi closed house cage in the fourth week resulted in body weight 1552 g with PBB of 578 g, the mortality rate was 4.34%, then the FCR was 1.43, and the IP was 372. When compared to the open house cage, the temperature in the semi-closed house cage is more conducive to broiler chicken growth. Broiler chickens perform differently in open-house and semi-closed-house cages due to variations in temperature and humidity. The performance of semi-closed house cages is superior to that of open house cages.
