Respon produktivitas dan kualitas susu pada suplementasi sabun mineral dan mineral organik serta kacang kedelai sangrai dalam ransum ternak ruminansia
Responses of productivity and milk quality on suplementation of mineral soap, organic minerals and roasted soybeans in ruminant diets
MetadataShow full item record
Milk production and quality are limited by feed quality either macronutrient or micronutrient. The objectives of this study were to protect essential fatty acids from degradation of rumen microbes, increase ruminant productivity, increase CLA and omega-3 content of milk. The experiment was divided into 3 parts. The first experiment was supplement production. The second experiment was evaluation of the productivity response of sheep to supplements. Thirty two Garut sheep (initial body weight of 22.38±3.56 kg) were assigned into a randomized complete block design with 8 treaments. Body weight was used as a block (4 blocks). Eight rations evaluated in this trial were FO: basal diet + fish oil, CO: basal diet + corn oil, CaFO: basal diet + calcium soap of fish oil, CaCO: basal diet + calcium soap of corn oil, ZnFO: basal diet + zinc soap of fish oil, ZnCO: basal diet + zinc soap of corn oil, RS: basal diet + roasted soybeans, MM: basal diet + mineral mix. The experimental diets were offered for 8 weeks. The third experiment was designed to measure milk yield and quality responses of dairy cattle to supplement. Twenty lactating Frisian Holstein cows (initial weight of 361.4 ± 40.39 kg) were assigned into a randomized complete block design with 5 treatments and 4 block. The treatments were B: basal diet, RS: B + roasted soybeans, MM: RS + mineral mix (organic-Zn, Cu, Cr, Se), CaCO: MM + calcium soap of corn oil, CaFO: MM + calcium soap of fish oil. The experimental diets were offered for 2 weeks preliminary and 9 weeks of observations period.
