Future Developments in Poultry Nutrition
Developments in poultry nutrition have generally been driven by the need to sustain genetic potential within the confines of ever evolving systems of poultry production. Over the last 50 years we have developed quite sophisticated systems for quantitating the available nutrients in both ingredients and diets and this has allowed us to provide birds with quite precise levels of nutrients require...
متن کاملFuture trends and developments in poultry nutrition
This paper gives recognition to the recent rapid technological, scientific and industrial changes that have taken place in the poultry sector, and uses these as a baseline for the prediction of future trends in nutrition. It is predicted that elevated levels of poultry feed will be required, in the fast-developing poultry sectors of Asia in particular, to meet the burgeoning consumer demand for...
متن کاملNatural Antioxidants in Poultry Nutrition: New developments
It is increasingly appreciated that diet plays a pivotal role in maintaining animal health, productive and reproductive performance of farm animals and poultry. Among many dietary factors natural antioxidants have special importance in the maintenance of high growth levels, reproduction and immuno-competence in poultry production. This concept is based on understanding the contribution of antio...
متن کاملRecent Developments in the Essential Fatty Acid Nutrition of Fish
Because of competitive interactions in the metabolism of polyunsaturated fatty acids, tissue and bodily requirements for each of the three dietary essential fatty acids in marine fish, 22:6n-3, 20:5n-3 and 20:4n-6, cannot be meaningfully considered in isolation. Rather, it is necessary to consider requirements in relative as well as absolute amounts, i.e. in terms of the ratio of 22:6n-3 : 20:5...
متن کاملMatrix-Variate Beta Generator - Developments and Application
Matrix-variate beta distributions are applied in different fields of hypothesis testing, multivariate correlation analysis, zero regression, canonical correlation analysis and etc. A methodology is proposed to generate matrix-variate beta generator distributions by combining the matrix-variate beta kernel with an unknown function of the trace operator. Several statistical characteristics, exten...
