Probiotic mixed feed and method for adjusting environment in plateau livestock and poultry breeding house

Abstract

The invention discloses a probiotic mixed feed and a method for adjusting the environment in a plateau livestock and poultry breeding house. The method comprises the steps of controlling the oxygen concentration of a chicken house and changing the daily ration structure of chickens. The henhouse oxygen concentration is controlled in a range of 25%-27%. The daily ration structure is changed by adding the probiotic mixed feed into the daily ration after the chickens are hatched for 14 days. The feed comprises 1-3% of a honeysuckle extract and 1-3% of an ox liver extract, and 1-5 * 10 < 10 > CFU of probiotics needs to be added every 1 g of the honeysuckle extract and the ox liver extract. The survival rate of chicken breeding in a high-altitude area is effectively increased, the daily weight gain, the daily feed intake and the feed utilization rate of the chicken breeding in the high-altitude area are improved.

Description

technical field [0001] The invention belongs to the field of poultry breeding, and relates to a chicken breeding method suitable for high-altitude areas, in particular to a probiotic mixed feed and a method for adjusting the environment in a plateau livestock and poultry breeding house. Background technique [0002] Broiler ascites syndrome is a non-infectious disease of broiler chickens characterized by obvious hydroperitoneal effusion, pulmonary congestion, pericardial effusion, right ventricular hypertrophy and liver tissue degeneration. It is most common in higher areas, also known as "broiler high altitude disease". The cause of the disease is complex and often varies greatly depending on the region, population density, management and feeding environment; its pathogenic mechanism is related to the hypoxia of the body caused by various reasons. The clinical incidence rate is about 5% to 10%, and it can reach about 30% in severe flocks, and the incidence and death rate c...

AI Technical Summary

Problems solved by technology

[0003] At present, the survival rate of chickens in high-altitude areas is improved by controlling the oxygen concentration in the chicken house and changing the diet structure. Although some researchers have done related research, the improvement effect of various methods on the survival rate of chickens is still insufficient.
