Rasio of Corn Stover and Pineapple Waste on Dry Matter, Organic Matter, Dry Matter Digestibility, and Organic Matter Silage (In Vitro)

Abstract

The increase in the population of ruminant livestock has led to a continuous increase in demand for animal feed, necessitating alternative feeds such as pineapple waste. The disadvantage of pineapple waste is that it deteriorates easily when stored for long periods, so it needs to be processed first, such as by making silage. This study aims to determine the quality of pineapple waste silage mixed with corn stover, based on dry matter content, organic matter content, and in vitro digestibility. The experimental design used was a completely randomized design with 4 treatments and 5 replicates. The treatments consisted of P1 = 90% corn stover + 10% pineapple waste, P2 = 80% corn stover + 20% pineapple waste, P3 = 70% corn stover + 30% pineapple waste, and P4 = 60% corn stover + 40% pineapple waste. The data were analyzed using analysis of variance and Duncan's multiple range test. The results showed that the ratio of corn stover and pineapple waste had a significant effect (P<0.05) on the in vitro dry matter and organic matter digestibility but had no significant effect (P>0.05) on the dry matter and organic matter content of silage. Higher use of pineapple waste up to 40% can increase the digestibility of dry matter and organic matter. It was concluded that the best digestibility of dry matter and organic matter in silage was in P4 with a ratio of 60% corn stover and 40% pineapple waste.
