In recent years, there has been an upsurge of sheep raising in various places. In order to obtain higher economic benefits, distiller's grains are widely used in sheep feed pellet production lines. Distillers grains are a by-product derived from the processing of grain and fruits. Generally divided into beer lees, white wine lees, fruit lees, grain lees and other four categories. The content of crude protein in the dry matter of distiller's grains is 8% -25%, the digestive energy is 6 MJ / kg, and the content of B vitamins is rich. It is a feed resource that can be fully utilized in sheep production.
Application of Distillers Grains in Sheep Feed Pellet Production Line
Distillers grains are a by-product of the brewing process. It not only contains a certain percentage of grain, but also contains rich crude protein, which is about 2-3 times higher than the corn content. It also contains a variety of trace elements, vitamins, yeast, etc., among which The content of lysine, methionine, and tryptophan is also very high; its crude fiber content is low, it has good palatability and digestibility, and it has the effect of increasing appetite; feeding lees to sheep is about 40- In about 50 days, you will find that the sheep's fur is brighter and softer, and not picky. The sheep fed with distiller's grains have good meat quality, fine fiber, fresh color and toughness after slaughter.
Feeding sheep with distiller's grains is simple, saves time and labor, and can also reduce the incidence of parasitic and rot-foot disease in sheep. At the same time, it can promote weight gain and lactating sheep can increase milk production.
Although there are some nutrients that can be used by sheep in distiller's grains, there are also some by-products of fermentation, such as residual alcohol, alkyd and other rancid substances, pectinic acid and formaldehyde in fruit lees, etc. Development has some impact. Distillers grains contain a certain amount of water, and if not processed in time, it will produce miscellaneous flavors and affect the appetite of sheep. Distillers grains are generally only used for fattening sheep, not for breeding rams, pregnant ewes and suckling ewes.
the use of lees to raise sheep
Feeding sheep with distiller's grains cannot be fed separately, but must be supplemented with concentrate and trace elements. Taking corn distillers grains, the diet composition of each sheep can be: 1 kg of corn distillers grains, 0.75 kg of grass powder, and 0.25 kg of corn flour. It would be more convenient and time-saving if these costs could be made into pellet feeding with a feed pelletizer according to a certain proportion. The daily weight gain of lambs fed by this method increased by 7%, and the survival rate of lambs increased by 15%.
If it is beer lees, it should be fed with corn flour, bran, soybean meal, etc., or it can be mixed with corn stalks in a certain ratio (corn stalks and beer lees 4: 1) and then produced by sheep feed granulators to produce pellet feed. Feed. The experiments showed that the mixed silage of beer lees and corn stalks had a 12.5% increase in body weight compared with corn stalks lactating milk goats alone, and the average daily lactation volume was 0.25 kg more per cow, and the milk production increased by 8.8%.
