Research ArticleOpen accessEvery word in the titleExtrusion of Peas (Pisum sativum L.): Effects on the Apparent Metabolisable Energy and Ileal Nutrient Digestibility of BroilersCatootjie L. Nalle, Ganesharanee Ravindran, Velmurugu RavindranProblem statement: The potential feeding values of grain legumes, such as peas (Pisum sativum), are limited because of the presence of anti-nutritional factors. In particular, protease inhibitors are of interest, but these can be readily destroyed by thermal treatments. In the present study, the influence of extrusion on the chemical composition and nutritive value of peas was evaluated. Approach: Two … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 1 · 26 Apr 2011 · 8,415 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of N and K Fertilizers on Nutrient Leaching and Groundwater Quality under Mature Oil Palm in Sabah during the Monsoon PeriodPetronella G. Ah Tung, Mohd Kamil Yusoff, Nik Muhamad Majid et al.Problem statement: The oil palms are mainly grown in the humid tropics with high rainfall. Soluble Nitrogen (N) and Potassium (K) fertilizers are commonly required by the oil palm plantations to maximize palm productivity due to the highly weathered soils with low fertility. Thus, leaching losses of N and K nutrients may be unavoidable and these nutrients may move further … …American Journal of Applied Sciences, Vol. 6, Issue 10 · 31 Oct 2009 · 10,143 accessesView PDFCite
