Abstract

This study aims to determine the nutritional content and fermentation conditions of whole-plant corn (WPC) silage cultivated in rice fields during the dry season from various varieties with additives. This study consisted of 2 treatments, namely V1: Lamuru corn variety and V2: Pioneer P32 corn variety, and 3 groups, namely K0: control, K1: additive rice bran, and K2: additive molasses. The results showed that corn varieties did not significantly affect DM, OM, CP, EE, NFE, Ash, NDF, and ATL. However, hemicellulose levels of V1 were higher, and the CF, ADF, Cellulose, and lignin levels of V1 were lower. Adding additives did not affect DM, CP, CF, NFE, ADF, NDF, cellulose, lignin, and ATL content. Adding rice bran significantly decreased the OM but increased the EE, Ash, and hemicellulose content. Adding molasses significantly decreased the OM content but increased the Ash content. Corn plant varieties did not affect pH, lactic acid, VFA, and ammonia, but the soluble sugar content in V1 was significantly higher. Adding rice bran increased pH and ammonia but did not affect lactic acid, soluble sugars, and VFA. Adding molasses decreased the pH and increased ammonia content but did not affect the lactic acid, soluble sugar, and VFA. Based on the research results, it can be concluded that WPC silage cultivated in rice fields during the dry season on the Lamuru variety has better nutritional content, but the fermentation parameters are the same as Pioneer P32. The addition of additives reduced some of the nutritional content, and fermentation parameters of WPC silage.
