In this chapter methods in feeding and how to evaluate broilers more efficiently with minor references to other poultry are highlighted. Topics discussed include predicting feed intake, nutrient response, feed evaluation, and digestive tract optimization.

The clinical signs of Stenocarpella maydis neuromycotoxicosis in guineapigs as models for the condition in ruminants in South Africa ingesting maize (Zea mays) contaminated with the fungus are described.

Many of the nutritional challenges posed by alternative systems can be addressed by application of existing scientific knowledge. However, regulations applied to alternative systems may limit the nutritionist's freedom of action, particularly with regard to the ingredients which can be used to...

Seed vigour testing provides valuable information for assessing seed lot quality. However, vigour testing has not experienced widespread use because it is labour-intensive, high in cost and the test results often vary from laboratory to laboratory. An automated seed vigour assessment system is...

Paysonia perforata (Rollins) O'Kane and Al-Shehbaz, and P. stonensis (Rollins) O'Kane and Al-Shehbaz are rare winter annuals found in frequently disturbed habitats, such as agricultural fields on floodplains. Both species are threatened by the loss of habitat, by its conversion to uses other than...

With the aim of improving soil productivity a shift in secondary natural vegetation was induced with cropped plants in a collaborative project utilizing improved fallows for maize production under a slash and burn system. A survey of 150 families, two experimentation peasant groups and three formal ...

This chapter discusses the role of proliferating cell nuclear antigen-associated proteins during maize seed germination. Results of various experiments show that the initiation of the cell cycle is an important event for germination establishment and completion.

This chapter describes translational control by different catabolite activator protein (CAP)-dependency in 2 selected subpopulations of maize-stored mRNA during germination (0 and 24 h). It is evident that there are mechanisms of translational control that specifically determine gene expression...

This chapter discusses a mutation, long cell (lc), in maize which is lethal and recessive. Lethality is produced by a general process of programmed cell death throughout the embryo.

To identify protein expression patterns related to cold germination (CG), recombinant inbred lines (RILs) that are divergent for CG and produce reciprocal F1 hybrids from them were identified. Reciprocal F1 hybrids showing differential phenotypes for CG were profiled for protein expression. RILs...
