Feedstuff additive used for improving low-temperature resistance stress of chicks for meat

Abstract

The invention belongs to the filed of feedstuff additives, in particular to a feedstuff additive used for improving the low-temperature resistance stress of chicks for meat, which comprises the following ingredients in part by weight: 3 to 5 parts of codonopsis pilosula, 3 to 5 parts of astragalus mongholicus, 2 to 4 parts of malt, 3 to 5 parts of rhizoma atractylodis macrocephaiae, 1 to 2 parts of liquorice and 1 part of monkshood. The feedstuff additive of the invention is added into the feedstuff according to the proportion of adding 200 g medicine powder into 100 kg feedstuff, the feed intake and the digestive absorption of the chicks for meat are promoted, the immunity of the chicks is improved, the utilization of the feedstuff is improved by 3 to 5 percentage points, the output-input ratio is improved by 3.2 to 5.0 percent, the body weight of the chicks for meat maintains stable growth under the low-temperature raising condition of the chickens for meat, the chickens for meat can be output to the market at normal time, the economic benefit of each chicken for meat can be improved by 0.5 to 1 yuan, and the death rate is reduced by 1 to 3 percentage points. The Chinese herbal medicine additive of the invention has wide raw material sources, low price, safety, innocuity, no medicine resistance and no medicine residue in meal products, and the additive of the invention belongs to an ideal low-temperature resistance stress additive substitute product in winter.

Description

【Technical field】 [0001] The invention belongs to the field of feed additives, in particular to a feed additive for improving the low temperature stress resistance of broiler chicks. 【Background technique】 [0002] The most critical management technology in the broiler brooding period is the regulation and management of temperature. After 4 weeks of age, chicks have a certain ability to regulate their own body temperature, but they are still imperfect and are quite sensitive to changes in external temperature. If the temperature is too high, the body heat and water loss of the chicks will be affected, the appetite will be reduced, a large amount of water will be lost, the metabolism will be blocked, the growth and development will be slow, the body will be weak, the resistance will be reduced, the body will be susceptible to colds or respiratory diseases and pecking habits, and the mortality rate will increase; If the temperature is too low, the chicks cannot maintain the b...
