The effects of different water quality parameters on aquacultured species and how to measure and maintain these parameters at optimum levels are discussed.

The clinical aspects, diagnosis, and management of diseases affecting the haematopoietic and haemolymphatic system in cattle were discussed. Highlights focused on the role of the thymus, hemal nodes, tonsils, peyer's patches, bone marrow, and reactive lymphoid hyperplasia. Congenital disease which...

As much as 12% of the world's soils may suffer excess water so that flooding is a major limiting factor on crop production in many areas. Plants attempt to deal with submergence by forming root aerenchyma to facilitate oxygen diffusion from the shoot to the root, initiating a hyponastic response...

This chapter describes the physiological responses of seeds to light and their interaction with environmental factors other than light (such as temperature, water potential and nitrate). Mechanisms underlying these light responses and the ecological significance of the various light responses in...

This chapter discusses the effects of soil chemicals on seed dormancy and germination, and on seed bank dynamics. The occurrence, signal translation, and mechanisms of action are discussed for some of the most important chemical cues (nitrate, allelochemicals, allelochemical inhibitors and...

In growing cereal and legume seedlings arsenate is more toxic for root growth than shoot growth. Arsenate treatment affects the activity of antioxidant scavenging enzymes, level of oxidative stress markers, sugar and starch contents as well as carbohydrate metabolizing enzyme activities causing...

This chapter presents some of the optimization modelling techniques that can be used to reduce the environmental impacts of livestock and assess the effects of environmental policies on the production system. Feed management practices that can reduce methane emissions and mineral excretion from...

This chapter attempts to integrate air and water quality issues in animal agriculture. The chapter provides discussion on whole-farm modelling; integrated farm system model; and production systems evaluations.

This chapter covers the most important toxins found in rabbit feeds. Focus is given on goitrogens, gossypol, lectins (haemagglutinins), mimosine, mycotoxins, nitrates, oxalates, saponins, pyrrolizidine alkaloids, trypsin inhibitors, urea, poisonous plants, herbal remedies and agricultural chemicals ...

This chapter covers the historical development and range and scope of growth promoters, performance enhancers and feed additives as well as the possible alternative strategies for their use in livestock feeding. The classification of growth promoters and performance enhancers, discovery and...
