Application of weighted goal programming in the optimization of rations for sport horses
Journal Title: Journal of Animal and Feed Sciences - Year 2013, Vol 22, Issue 4
Abstract
The objective of this study was to develop a model to assess economical and balanced feed rations for sport horses. It was based on nonparametric modelling with a combination of linear programming and a multiobjective optimization technique: weighted goal programming. The method incorporates multiple goals into optimization. The technical data presented the feed nutritional value (dry matter, metabolizable energy, metabolizable protein, etc.) and nutritional requirements, which were represented in weighted goal programming as targets. The model was tested for optimization of winter and summer feed rations, where summer feed rations are more expensive but more balanced. Optimization results show that the method of weighted goal programming is more accurate and useful in practice compared with linear programming, where only one goal (economically optimal feed rationing) is taken into account.

Potential of phytofactors to mitigate rumen ammonia and methane production
The increase in the intensity of ruminant production determines changes in the rumen feed conversion and thus, among other, may increase pool of greenhouse gases emission. The ineffective digestion process and changes in...
The effect of sodium butyrate on calf growth and serum level of β-hydroxybutyric acid
The experiment was carried out on 40 Polish Black-and-White HF bull calves (52-87% of HF blood) aged from 9 and 12 days at the beginning of the experiment to 90 days at its end. From the beginning of the trial the calves...
Peripheral ghrelin inhibits feed intake through hypothalamo-pituitary-adrenal axis-dependent mechanism in chicken
It is known that centrally injected ghrelin is an anorexigenic peptide in chicken. Its activity is not mediated by NPY/AgRP - producing neurons but through the corticosterone releasing hormone (CRH) - expressing neurons...

The objective of the study was to evaluate the effects of dietary phytic acid (IP6) on the apparent total tract digestibility (ATTD) of main nutrients and apparent absorption of minerals in mink (Mustela vison). A basal...
Localization of kisspeptin neurons in the hypothalamus of peripubertal female lambs; possible connection with gonadotrophin releasing hormone and neuropeptide Y neurons
Hypothalamic peptide kisspeptin (kp) plays a major role in the initiation of pubertal events in mammals through the activation of gonadotrophin- -releasing hormone (GnRH) neurons. The present study was designed to analys...
