Feed additive capable of adjusting heat stress broiler nutrient absorption and metabolism

Abstract

The invention discloses a feed additive capable of adjusting heat stress broiler nutrient absorption and metabolism. The feed additive comprises, by weight parts, 300-360 parts of fatty powder, 36-40 parts of stearyl citrate, 32-36 parts of L-carnitine, 0.006-0.010 part of chromium nicotinate, 8-12 parts of lipoic acid, 10-14 parts of vitamin C, 6-10 parts of vitamin E, 200-240 parts of montmorillonite and 288-408 parts of spirulina powder. The invention further discloses a method for using the feed additive capable of adjusting heat stress broiler nutrient absorption and metabolism. According to the feed additive, the growth velocity of broilers can be improved greatly, the feed conversion rate is improved, the death rate of the broilers is reduced by effectively preventing nutrition metabolism diseases caused by heat stress, the cultivation earning is improved, and the feed additive is simple, convenient, practical, safe and reliable, can effectively reduce cultivation cost and is particularly suitable for medium and large intensive farms for feeding the broilers in high-temperature seasons.

Description

technical field [0001] The invention relates to the technical field of broiler feed additives, in particular to a feed additive capable of regulating nutrient absorption and metabolism of heat-stressed broiler chickens, and a use method thereof. Background technique [0002] With the rapid development of broiler farming, intensive farming has become the main mode of current broiler farming. High-density feeding makes broiler chickens very prone to heat stress, which reduces their production performance, reduces their immunity, and increases the mortality rate, which brings huge economic losses to broiler chicken farming. Patent 200910219814.3 discloses an anti-heat stress Chinese herbal medicine additive for broiler chickens and its use method. The broiler chicken anti-heat stress composition composed of jujube saponin, ethoxyquinoline and corn gluten powder is added to the broiler diet at a ratio of 0.125 to 0.5:1000 Chinese herbal medicine feed additive, the feed additive...

High-density feeding causes broiler chickens to be prone to heat stress, resulting in reduced production performance, decreased immunity, and increased mortality, which brings huge economic losses to broiler chicken farming.

Patent 200910219814.3 discloses an anti-heat stress Chinese herbal medicine additive for broiler chickens and its use method. The broiler chicken anti-heat stress composition composed of jujube saponin, ethoxyquinoline and corn gluten powder is added to the broiler diet at a ratio of 0.125 to 0.5:1000 Chinese herbal medicine feed additive, the feed additive focuses on the sedation and anti-oxidative stress of broilers, ignoring the important factors that lead to the decline in the performance of heat-stressed broilers, that is, the decrease in feed intake of broilers and the important nutrients in the body during heat stress Metabolic disturbances, therefore, it is difficult to achieve optimal heat stress resistance in broilers

By increasing the proportion of energy feed, increasing the nutrient concentration of the diet, and reducing the metabolic heat production of broilers to reduce the body temperature of the animal is the most researched at present, and some results have been achieved, especially adding oils and fats to the feed to increase the energy effect is better, but because in practice It is difficult to add oil during production, and the feed with added oil is not easy to preserve, which can easily lead to mildew of the feed
