yeast protein powder is a replace source of fish meal.feather meal.

As aquatic animal nutrition protein raw feed formula
In the traditional feed formulations, are used as the main animal protein fishmeal sources. With the increasing development of aquaculture, fish meal requirements increased dramatically, and even fish in short supply, prices rise year by year, as a constraint to aquaculture development an important factor. Feed yeast is an ideal alternative to fishmeal protein sources, not only the high protein content, good quality, and can increase production, improve the tail weight gain and reduce feed coefficient, reduce farming costs, improve economic benefits
As a feed additive immunomodulatory agent
The feed yeast, yeast cell wall contains many active ingredients, mainly β-glucan (about 57.0% dry weight) and mannose oligosaccharide (about 6.6% of dry weight). They are able to bacteria, fungi and viruses that cause diseases and because transportation, vaccination, and climate change caused by the reaction of non-specific immunity stress. Add yeast in the feed additive, can enhance immune function of aquatic animals, aquatic animal disease increase capacity, improve seedling survival.
Aquatic animal feed as the expression of genetically engineered receptor system
With genetic engineering technology in aquatic animal nutrition applications, humans have developed more and more aquatic animal feed and additive genetic engineering. The aquatic animal feed and additive genetic engineering developed a key technology is to find a good exogenous recombinant protein expression host. As a eukaryotic yeast, it expressed exogenous translational protein processing, secretion, can express their natural protein product with the same or similar form; and as a fungus, it can like bacteria could do so at an inexpensive medium blooms, coupled with its relatively clear mechanism of regulation of gene expression, genetic easy to operate, has become the preferred yeast expressing exogenous protein receptors. Some growth hormones, enzymes, antimicrobial belly has been successfully expressed in yeast, the yeast expression system which shows the development of feeds and additives genes broad application prospect.
In the livestock feed yeast Diets
Although it is not pigs and other livestock predators, however, a certain amount of protein include animal protein, including for them, but it is essential. The feed yeast is precisely the best cheapest most abundant animal protein substitutes, plus yeast also contains a lot of vitamins, so it is keeping a very significant effect. According to many years of breeding experience abroad, if the proportion of 5% in the general will feed yeast mixed pig feed, pig feed yeast weight gain when no more than 20-30%. Cows with feed yeast, and make their body weight increased by 24%, ie one kg feed yeast can exchange one kilogram of beef, seven kilograms of milk and so on. All in all, in the general diets fed to livestock feed yeast suitable, not only can it gain weight, but also can improve the meat.
