When the scientific use of mutton fattening feed additives, can promote the growth and improve metabolism, improve the feed remuneration, effectively increase output, save feed sheep, reduce cost, to increase income. Common fattening sheep feed additive has the following kinds.
A, mo can, (mo can, sodium, indraft-into-rumen, MengNingSu). Its function is to control and improve efficiency, improve rumen fermentation increase speed and feed conversion rate. Mo can bacteria in the food additives, mutton for 25-30 mg, must pay attention to the full and mix. Early feed amount less, gradually increased to provisions doses. Fold the sheep feeding mo can bacteria, plecata comparable control more than 35% increase, feed conversion rate increase 27%, To fatten feeding goats, mo can bacteria can improve plecata 16 ~ 32%, feed conversion rate increase 3% ~ 19 percent.
Second, minerals additives. Minerals additive is indispensable to fatten sheep nutrients. Besides, adding local food additives used outside, still can form such as salt brick. Brick of salt is added salt as the carrier, calcium, phosphorus, copper, zinc, manganese and iron, selenium elements, etc. When using, can hang in the barn or stadium, also can hang in the water pond or feeding trough, its free suckle.
Third, feed. Commonly used feed moderator has sodium bicarbonate and magnesium oxide. In the strength of the sheep, usually fatten JingSiLiao proportion in the diet, the body can produce excess acidity material, cause gastric bowel to feed the digestive capability. Add in feed, can increase the alkaline, make rumen rumen environment is more suitable for the growth of microorganism, and can increase appetite, thus improving the utilization of digestive feed. Sodium bicarbonate and magnesium in the ratio of 2 ~ 3 advisable. The dosage of sodium bicarbonate to mix the 1.5% ~ 2%, grain or the date of dry matter of grain 0.75% ~ 1%. The dosage of magnesium oxide for mixture 0.75%, accounting for the entire day ~ 1% of dry matter of grain 0.3%-0.5%. Experiments prove that use a combination of both.
Four, antibacterial agent of growth. Antimicrobial agents have the growth KuiYiChun, bacillus peptide zinc. They can selectively inhibiting pathogenic escherichia coli, and does not affect the normal flora. It can also affect the body’s metabolism, promote the assimilation of protein, so as to promote the growth of mutton. Every kilogram mutton diet in the dry matter KuiYiChun additives for 50-80 mg, bacillus peptide zinc additives for 10 ~ 20 milligrams, can make the lamb plecata increase 5% ~ 10%, added must concentrate and mixing.
