Chemical composition and ruminal degradability of grain pearl millet grown in southwestern Quebec

Abstract

. 2008. Chemical composition and ruminal degradability of grain pearl millet grown in southwestern Quebec. Can. J. Anim. Sci. 88: 71Á77. The objectives of this study were to determine the chemical composition and ruminal nutrient degradabilities of grain of five hybrids of pearl millet grown in southwestern Quebec. Hybrids were selected because they were poor hosts of the widely prevalent root lesion nematode (Pratylenchus penetrans). Neutral detergent fiber and acid detergent lignin were similar for all hybrids. However, acid detergent fiber (ADF) was higher for CGPMH-1 than CGPMH-7 and CGPMH-38 and was higher for CGPMH-11 and CGPMH-20 than CGPMH-7. Starch content was higher for CGPMH-7 (668 g kg (1 DM) than the other hybrids (average 635 g kg (1 DM). Crude protein (CP) was lower for CGPMH-7 (141 g kg (1 DM) than the other hybrids (average 181 g kg (1 DM). Fatty acid content was higher for CGPMH-11 and CGPMH-20 than CGPMH-38. Linoleic acid was the most abundant fatty acid in all hybrids and was lower for CGPMH-38 than the other hybrids. Ruminal dry matter degradability was similar for all hybrids (average 69.5%). However, ruminal CP and starch degradabilities were higher for CGPMH-1 and CGPMH-20 than CGPMH-11 and CGPMH-38. It was concluded that grain concentrations of CP, ADF, and starch, and ruminal CP and starch degradabilities of pearl millet varied among hybrid.Key words: Chemical composition, Pearl millet, Ruminal degradability Mustafa, A.

L'e´tude devait e´tablir la composition chimique et la capacite´de de´gradation dans le rumen du grain de cinq hybrides de millet a`chandelle cultive´s dans le sudouest du Que´bec. Les varie´te´s avaient e´te´se´lectionne´es parce qu'elles constituaient un pie`tre hoˆte au tre`s courant ne´matode des racines (Pratylenchus penetrans). La concentration de fibres au de´tergent neutre et de lignine au de´tergent acide e´tait semblable pour tous les hybrides. Celle de fibres au de´tergent acide (FDA) e´tait toutefois plus e´leve´e chez CGPMH-1 que chez CGPMH-7 et CGPMH-38, et plus e´leve´e chez CGPMH-11 et CGPMH-20 que chez CGPMH-7. CGPMH-7 pre´sentait une plus forte teneur en amidon (668 g par kg de matie`re se`che) que les autres hybrides (moyenne de 635 g par kg de matie`re se`che). CGPMH-7 e´tait moins riche en prote´ines brutes (141 g par kg de matie`re se`che) que les autres hybrides (moyenne de 181 g par kg de matie`re se`che). La concentration d'acides gras e´tait plus e´leve´e chez CGPMH-11 et CGPMH-20 que chez CGPMH-38. L'acide linole´ique est l'acide gras le plus abondant, peu importe la varie´te´, mais sa concentration est plus faible chez CGPMH-38. La matie`re se`che se de´grade dans le rumen de la meˆme fac¸on chez les diffe´rentes hybrides (moyenne de 69,5 %). Ne´anmoins, les prote´ines brutes et l'amidon de CGPMH-1 et de CGPMH-20 se de´gradent mieux que ceux de CGPMH...

Potassium and Manganese Fertilization and the Effects on Millet Seed Yield, Seed Quality, and Forage Potential of Residual Stalks

“…While crude protein and oil contents in this study are lower than that reported for some pearl millet hybrids in Canada [32], protein content are within the range 88 -209 g•kg −1 previously reported for pearl millet [33]. TifGrain 102 millet has been reported before where it is indicated to have comparable total metabolizable energy (TME) and higher protein content than corn [34].…”

Comparison of corn-based and Canadian pearl millet-based diets on performance, digestibility, villus morphology, and digestive microbial populations in broiler chickens

“…A major constraint lies in the unavailability of a nutritionally rich PM variety that could adapt well to the harsh Canadian growing conditions and relatively short summer season. It is also worth mentioning that the concentrations of ME, CP, amino acids, and antinutritional factors vary greatly between different PM varieties (Buerkert et al, 2001;Mustafa et al, 2008).…”

Replacing corn with pearl millet (raw and sprouted) with and without enzyme in chickens' diet

“…Our findings are in agreement with other report that enzyme supplementation of corn‐based diets did not alter BW and FCR (Madrid et al., ). To the best of our knowledge, there was little study evaluating the effects of enzyme addition to pearl millet‐based diets on broiler performance, as the arabinose and xylans are the major water‐soluble NSP in PM grains (Mustafa et al., ). In this study, the only observed positive effect of enzyme supplementations on broiler performance was increased performance of birds that consumed of the PM diet compared with the CTL diet.…”

“…The investigation of sprouting of pearl millet‐based diets on broiler performance is another novel approach of this study. Arabinose and xylans are the major water‐soluble NSP in PM grains (Mustafa et al., ), and dietary inclusions of this grain necessitate enzyme supplementation or sprouting to alleviate the problems of increased viscosity, reduced nutrient utilization and depressed growth in broilers (Shirzadi et al., ). Therefore, we can assume that pearl millet‐based diets contained some insoluble NSP because of the positive effects that we observed with ES and sprouting.…”

“…Pearl millet contains fewer antinutritional factors than many other grains (Choct, ) and possesses unique nutritive values that are attractive for poultry nutrition. Arabinose and xylans are the major water‐soluble NSP in PM grains (Mustafa et al., ). In comparison with corn, PM possesses comparable (Davis et al., ) or better (Andrews and Kumar, ) ME levels and higher amino acid concentrations (Baurhoo et al., ).…”
