Common Beef cattle Feed Additives

Feed additive refers to a small amount or trace substance added in the process of feed production, processing and use, which plays a significant role in feed, and is an inevitable raw material used in modern feed industry. let's take a look at the common beef cattle feed additives.

sodium bicarbonate

The acidic environment of rumen has an important effect on the activity of microorganisms, especially when changing feed (such as changing roughage to high concentrate in the later fattening stage), it can significantly decrease the pH value of rumen and affect the activity of rumen microorganisms. and then affect the conversion of feed. After adding 0.7% sodium bicarbonate to beef cattle feed, the pH value of rumen can be maintained in the range of 6.2-6.8, which meets the needs of rumen microbial proliferation, so that the rumen has the best digestive function, increases feed intake by 9%, and increases daily gain by more than 10%.

Monensin

The application of monensin in the high concentrate fattening of shelf cattle can increase the production of propionic acid, reduce the degradation of protein in the rumen, increase the total amount of rumen protein, increase net energy, and improve the utilization rate of nitrogen. and make the intestinal wall thinner, which is conducive to the penetration and absorption of nutrients, but also stimulate the pituitary secretion of hormones to promote growth and development, and then increase the rate of weight gain. If the concentrate mixed with monensin is mixed with roughage, the daily gain can be increased by 15% and 20%.

Rare earth elements

By adding rare earth 1000ppm to the diet of fattening cattle, the daily gain was increased by 26.63%, the feed to meat ratio was reduced by 21.30%, and the feed conversion efficiency was increased by 23.39%.

Probiotics

Probiotics is a kind of microbial preparation which can replace or balance one or more bacteria in the gastrointestinal microecosystem, such as lactic acid bacteria, bifidobacteria, subtilis, etc., which can stimulate the proliferation of their own bacteria and inhibit the growth of other bacteria; produce enzymes, synthesize B vitamins, improve immune function, promote appetite, reduce the incidence of gastrointestinal diseases, and have the effect of promoting fattening. The addition amount is generally 0.02% 0.2% of the cattle diet.

Non-protein nitrogen

Urea is the most commonly used non-protein nitrogen. The nutritional value of urea per kilogram of urea is equivalent to that of 5 kilograms of soybean cake or 7 kilograms of flaxseed cake. 20-30 grams of urea per kilogram of body weight is mixed in concentrate or mixed with roughage, or urea is dissolved in water and mixed or sprayed on hay. Or urea, corn and syrup mixed into liquid feed, or adding urea to make silage feed.
