The Effect of Long Time of Storage on Physical Quality, Nutrient Content, and In Vitro Digestibility of Cattle Complete Feed

Abstract

This research aimed to determine the effect of a long time of storage on physical quality, nutrient content, and in vitro digestibility of cattle complete feed. The research was carried out in Sidomulyo Village, Gunem District, Rembang Regency from March to October 2019. 15 drums of cattle complete feed (@ 25 kg) were used as materials. It was made from rice bran 4.10%; Penisitum purpureum (Odot grass) 60.60%; rice straw 12.70%; gliricidia 8.30%; corn stover 10.80%; molasses 1.60%; minerals 1.60%; table salt 0.20%; and starter 0.30%. This research used one treatment factor, namely the length of time of storage of cattle complete feed. These consisted of five treatments, namely: long time of storage of 0.0; 1.5; 3.0; 4.5; and 6.0 months. Each treatment was repeated three times. The cattle complete feed with all the long time of storage preferred by the cattle. The cattle complete feed could be stored in good quality for 3 months. The storage over 3 months caused the quality of the cattle’s complete feed to decrease. The crude protein content decreased with increasing storage time. The long time of storage did not affect the in vitro digestibility of dry matter and organic matter. the impact of feeding techniques was investigated. Applying the whole feed diet during the growing phase and up until the early fattening phase, and then concluding with concentrate and forage, did not significantly affect 1) SCF, 2) TMRGSCF
