Abstract
Improving Sakura Block Quality as Feed Supplement to Optimize Rumen Fermentation Products and Nutrients Digestibility In Vitro
Highlights
Sakura block (Sago arenga block) is a feed supplement as a modification of Urea Molasses Multinutrient Block (UMMB) with a mixed formulation of local raw materials to support the energy, nitrogen, and other nutrient needs of ruminants to get quality feed
The use of sakura block as a feed supplement has been tested on ruminants and has been produced by the Nutrition Laboratory, Department of Animal Husbandry, Bengkulu University
Sakura block consists of 72.59% Total digestible nutrient (TDN). 89.19% dry matter, 17.39% crude protein, 3.73% crude fiber, 3.36% crude fat, 7.55% ash and 65.1% Nitrogen Free Extract (NFE). 10% of the total need for dry matter supplementation can increase body weight gain of 0.6 kg per day on Kaur cattle Jarmuji et al, 2017) and 0.50 kg per day on Bali cattle
Summary
Sakura block (Sago arenga block) is a feed supplement as a modification of Urea Molasses Multinutrient Block (UMMB) with a mixed formulation of local raw materials to support the energy, nitrogen, and other nutrient needs of ruminants to get quality feed. Sakura block provides a balance of energy, soluble nitrogen, and other nutrients for the growth and development of rumen microbes for livestock (Yanuartono et al, 2016). The contribution of rumen microbial protein in supplying amino acid needs for livestock is 70-100% (AFRC, 1992). Cattle with foragebased feed or agricultural waste for livestock protein needs are sourced from microbes up to 100% (Given et al, 2000). Apart from being a source of protein, rumen microbes contribute 70-85% of energy requirements in the form of volatile fatty acids (Dewhurst et al, 1986). 10% of the total need for dry matter supplementation can increase body weight gain of 0.6 kg per day on Kaur cattle Jarmuji et al, 2017) and 0.50 kg per day on Bali cattle Sakura block consists of 72.59% Total digestible nutrient (TDN). 89.19% dry matter, 17.39% crude protein, 3.73% crude fiber, 3.36% crude fat, 7.55% ash and 65.1% Nitrogen Free Extract (NFE). 10% of the total need for dry matter supplementation can increase body weight gain of 0.6 kg per day on Kaur cattle Jarmuji et al, 2017) and 0.50 kg per day on Bali cattle
