Abstract

Sorghum is a forage plant that has the ability to produce new shoots or saplings known as ratoons. This research aims to evaluate the nutritional dynamics and GE (gross energy) of Samurai II sorghum variety due to differences in treatment at harvest age and urea fertilizer dosage. This study used a completely randomized factorial design (3 x 3) with 3 replications. The first factor is the harvest age of 80, 85, and 90 days, and the second factor is the urea fertilizer dose of 200, 300, and 400 kg ha-1. The parameters observed were crude protein, crude fat, crude fiber, ADF, NDF and GE levels. The results of the research showed that the Samurai II variety of sorghum had a significant effect on dry matter due to the treatment of cutting age in the primary harvest and ratoon 1. Furthermore, there was a difference (P<0.05) due to the sorghum dose. application of urea fertilizer to crude fiber in the primary and ratoon 2 harvests. In the Samurai II variety of sorghum there was also an interaction between cutting age and the dose of urea fertilizer in the primary and ratoon 2 harvests on the NDF content produced. The nutritional value and GM content are still stable even when cut up to ratoon 2 (third harvest)

Abstract

Cultivation of forages from graminae and legumes is an alternative source of fiber feed to meet basic living needs and ruminant livestock production. This research aims to assess the nutritional and WSC content of various forages as indicators and considerations in making silage. The research used a completely randomized design with 5 treatments with 4 replications. Regarding the treatment of forage types, namely A = elephant grass; B = Gama Umami; C= Mexican Grass; D= Odot grass; D = Indigofera beans. The research parameters are crude protein (%), crude fat (%), dry matter (%), ash, crude fiber (%), water-soluble carbohydrates (%), and NDF and ADF content (%). The results showed that different types of forage had a significant effect (P<0.05) on the nutritional value and WSC content. The research conclusion was that Indigofera legumes and odot grass had the highest WSC content, namely 4.59% and 4.49%. Furthermore, indigofera legumes and odot grass also produce the lowest NDF and ADF values compared to other treatments, so they have the potential to be used as raw materials for making silage to support the availability of ruminant feed
