» Health starts in the gutImproving sows´ productivity by using probiotics
Sows´ productivity is the most important factor for economic and successful piglet production. Besides litter size and pre-weaning mortality, parameters as fertility, feed consumption and replacement rates have to be included in the assessment of the overall production costs. Sow longevity, body condition and reproduction performances are very closely related as sows with a lower weight loss during first lactation have an increased chance for fewer days open and an enhanced litter size in the subsequent reproductive cycle. » Copper in animal nutrition The novel solution is CoRouge
When selecting the source of trace minerals, all feed formulators are familiar with mineral oxides. They use or may use zinc oxide, manganese oxide, but why is copper oxide not a popular source of copper in animal nutrition? This review will give some reasons and will explain why the situation recently changed with the authorization of the monovalent form of copper oxide.» Lipase improves growth economicsNovel llipase optimises oil absorption from poultry diets
The objective for the rearing stage of this experiment was comparing the growing performance of broiler chickens to 42 days, fed a standard corn-soybean meal diet, against chickens fed a diet which had its energy reduced by 70-100kcal/kg and including 100ppm of lipase. The results of experiment showed that using 100ppm of lipase in the diets of growing broiler chickens allows reducing 70kcal/kg in the starter feed and 100kcal/kg in the grower feed, at the expense of palm oil, maintaining the birds’ growth.

The demands made of reducing nitrogen and phosphorus in pig feed have increased distinctly with the entry into force of the new Fertiliser Regulation. Optimising feed using standardised ileal digestible amino acids and digestible phosphorus contributes to lowering the N and P excretions. Accordingly the focus of feed optimising is shifting more and more from the actual feed composition to the effect of the feed in the animal. This has consequences for energy evaluation as well. The energetic feed evaluation based on the metabolisable energy (ME) describes the energy potential available to the animal for metabolism after digestion of the nutrients. It is of secondary importance for what performance this energy is needed. When used for growth or reproduction, about 25% of the ME is lost as heat.
