Nutrient Content andin situDisappearance in Genotypes of Buffelgrass (Cenchrus ciliarisL.)

Abstract

The aim of the study was to evaluate and to compare the dry matter production (DMP), chemical composition and in situ disappearance of dry matter (ISDDM), crude protein (ISDCP) and cell wall (ISDNDF) of 78 genotypes of buffelgrass (Cenchrus ciliaris L.) recently introduced to Mexico. I n addition, mineral content and potential intake of minerals by cattle consuming these genotypes was determined. Grasses were collected at the end of the autumn. The DMP (1-6 ton ha-'), crude protein (6-9%), ash (11-18%), cell wall (67-79%), cellulose (38-44%), hemicellulose (20-31 %), lignin (4-9%), insoluble ash (2-6%), ISDDM (50-62 %), ISDCP (53-74%) and ISDNDF (4642%) were significan~ly different among genotypes. With exception of one genotype all had sufficient protein to fulfill grazing growing cattle needs, whereas, digestible energy content of all grasses fulfilled the maintenance requirements of growing cattle. All grasses had Ca, Mg, K and Fe in sufficient amounts to meet maintenance requirements of a cow weighing 400 kg. However, P, N a and Cu in all grasses and Z n and M n in some genotypes were lower. Because of their superior DMP and good nutritional quality, genotypes identified as PI409377, PI409472, PI409373, PI4091 55 and PI409529 may be considered with higher potential to be used as good rain fed forages for grazing cattle.

Assessing genotypes of buffel grass (Cenchrus ciliaris) as an alternative to maize silage for sheep nutrition

“…, 367-432 and 34-60 g/kg for Organic Matter, crude protein, neutral detergent fiber, acid detergent fiber, cellulose and lignin, respectively, in five other C. ciliaris genotypes. The mean values for Organic Matter, crude protein, neutral detergent fiber, cellulose and lignin for 78 C. ciliaris genotypes evaluated in Mexico[38] were 861, 82, 734, 413 and 31 g/kg of dry matter, respectively. Additionally, the values for Organic Matter, crude protein, ether extract, neutral detergent fiber, acid detergent fiber, cellulose and lignin were 873, 41, 19.5, 682.3, 418.7, 360 and 55 g/kg of dry matter, respectively, for C. ciliaris…”
