Abstract

1. In vitro and in vivo assessment of the effect of initial moisture content and drying temperature on the feeding value of maize grain F. Huart, P. Malumba, S. Odjo, W. Al-Izzi, F. Béra, Y. Beckers British Poultry Science CrossRef

Highlights

  • Maize (Zea mays L.) is one of the main components of broiler diets

  • Maize grain is relatively low in crude protein, but high in crude fat and metabolizable energy value for broiler chickens (AMEN) in comparison with other cereals (European Table, 1989; Sauvant et al, 2004)

  • The results of our study indicate that some cultivars of maize can differ in the extent of nutrient digestion and in energy value

Summary

Introduction

Maize (Zea mays L.) is one of the main components of broiler diets. Tables on the composition and nutritional value of feedstuffs (Sauvant et al, 2004; Smulikowska and Rutkowski, 2005) usually contain only average values for components of NUTRITIVE VALUE OF MAIZE CULTIVARS FOR BROILERS maize, assuming slight varietal differences. Song et al (2003) reported that maize cultivars may differ in the content of protein and in their starch and fibre contents, as well as in nutrient digestibility and metabolizable energy (AMEN). According to Cowieson (2005) maize may contain from 71 g to 94 g of crude protein per kg, which is less than in wheat or barley. The most important storage protein in maize is zein, which is poor in the essential amino acids, tryptophan and lysine, the protein value of maize is poor
