Nutritive value of diferents silage sorghum (Sorghum bicolor L. Moench) cultivares - doi: 10.4025/actascianimsci.v34i2.12853

Abstract

ABSTRACT. Nutrition values of silages from different sorghum cultivars are evaluated. Five 26-kg castrated crossbred lambs, housed in pens equipped with feces and urine collectors for the study of their metabolism, were employed in a 5 x 5 Latin square experimental design. Treatments consisted of silage from five different sorghum cultivars: IPA 1011 and IPA 2564 (grain sorghum), IPA 2502 (dual purpose sorghum), IPA FS-25 and IPA 467 (forage sorghum). Protein level was corrected to 12% by adding a mixture of urea: ammonium sulfate (9:1). Treatments IPA 1011, IPA 2564 and IPA 2502 provided high intake of dry matter, total carbohydrate and total digestible nutrients, and low intake of neutral detergent fiber. Cultivars IPA 1011 and IPA 2564 provided high apparent crude protein digestibility coefficient, whereas cultivars IPA 1011 and IPA 2564 had high total digestible nutrient levels. All cultivars provided positive nitrogen. Owing to nutrient intake and digestibility values, grain sorghum silages evidenced high potential in ruminant nutrition.

Nutritive Value and Fodder Potential of Different Sorghum (Sorghum bicolor L. Moench) Cultivars

“…The accession TKSV 1126 recorded the highest mean for DDM of 66.31%, while the genotype TNS 623 observed high mean MER of 11.97%. Our results were in accordance with the findings reported by Mizubuti et al, (2002) and Barba et al, (2012).…”

“…Neutral detergent fibre ranged from 55.00 (TKSV 1126) and 72.00 (SPV 2123) per cent. Similar reports by Marsalis et al, (2010), Machado et al, (2011), Barba et al, (2012) and Matos et al, (2014) supported our findings. Lower the ADF, the feed is highly digestible (i.e., of high quality) and lower NDF leads to higher intakes (John, 2005).…”

<b>The quality of silage of different sorghum genotypes

“…Sorghum silage, when well fermented, presents minimum pH values around 3 to 7 days after ensiling, which are maintained for a long storage time (Fazaeli, Golmohhammadi, Al-Moddares, Mosharraf, & Shoaei, 2008). The pH stability in ensiling is due to interactions between dry matter concentration, the buffering capacity of the forage, the concentrations of soluble carbohydrates and of the lactate, and the anaerobic conditions of the medium (Borba et al, 2012).…”

Nutritional value of sorghum silage of different purposes

“…Sorghum (Sorghum bicolor (L.) Moench) is a crop similar to corn in regards to its agronomic and nutritional value. However, in terms of requirements, sorghum is an attractive alternative to corn because it is more adapted to drought and low soil fertility (Borba et al, 2012). Among sorghum types are grain, forage, and sweet sorghum, which differ in plant height and nutritional value.…”
