Abstract: This research identifies the preserving method of forage crops using silage method that will assist the farmers in combating drought during dry season. The preparation of silage required that the fodder be harvested, packed and covered in the process expelling oxygen to create an anaerobic environment. Lack of knowledge on preserving fodder crops is one of the factors that causes feed shortages during dry season. Poor nutrition is a major constraint to livestock in smallholder crop-livestock farming system, especially during the dry season when available feed quantity is low and quality extremely poor. The objective of the research was to determine the effects of legume inclusion on nutrient content of sorghum silage and to determine the effects of legume inclusion on ensiling quality of forage sorghum. Determination of nutrient composition (DM, CP, NDF, ADF, Ash) and silage quality (pH ammonia N) was conducted in the laboratory. Organoleptic observations were also used in determining the silage quality coupled with laboratory analysis for full determination. A pair t-test was used to compare means of nutrient composition of fresh material and ensiled forages. It was observed that they are nutrient losses before ensiling due to different factors. Incorporation of legumes in cereal silage has potential to increase protein concentration and the nutritional quality of silage. Sweet sorghum provided the fermentable carbohydrate for ensiling both crops. Forage legumes alone are difficult to ensile due to high buffering capacity though they have higher crude protein contents than whole crop cereal silages. The crude protein content of forages was lower in sole sorghum and there was no significance difference in sorghum grown with either of the legumes. Sole sorghum had higher fiber content than sorghum grown with either of the legume.
