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.

The association of brain derived neurotrophic factor gene variants with behaviour traits in sika deer (Cervus nippon)
It is widely accepted that brain-derived neurotrophic factor (BDNF) is involved in modulating behaviour performance induced by environmental conditions. The aim of this study was to study polymorphisms of the BDNF gene a...
Factors affecting the nutritional value of pea (Pisum sativum) for broilers
In a trial carried out on broiler chickens, the nutritive value of five pea cultivars (coloured-flowered: Turnia, Sokolik, Milwa, and white-flowered Muza and Cysterski) was determined. A total of 60 male Ross 308 17-dayo...
Endogenous synthesis of rumenic acid in humans and cattle
Recent results of biomedical studies suggest that rumenic acid (RA), the major isomer of conjugated octadecadienoic acids (CLA), appears to have beneficial health effects in humans. The major source of RA in the human di...
Effects of phytogenic products on in vitro rumen fermentation and methane emission in goats
This study evaluated the effects of addition of lucerne extract (LE), Artemisiae annuae extract (AAE), and mixed herbal medicine (MHM) into different goat diets on in vitro rumen fermentation and methane production. In a...
Changes in integrin-positive cells and T cell subpopulations in the peripheral blood and intestine of calves fed soya protein
integrin expression, 16 male 10-day-old Holstein calves were divided into two groups. For 28 days of the experiment, eight males were fed NutriMilk in which 50% of the crude protein was soya protein, and eight control an...
