Problems solved by technology

[0003] At present, Guangdong Province, where meat ducks are mainly raised, has a summer temperature exceeding 30°C for up to 5 months. The feed intake of meat ducks in high temperature seasons decreases by an average of 20%, and the average slaughter weight of meat ducks decreases by 0.25-0.5kg / piece. The average survival rate is reduced by 5-10%. Due to the reduction in final weight, the time to market is prolonged, and the material ratio is increased by 0.1-0.2, resulting in an average direct economic loss of 2-3 yuan per bird

Abstract

The invention relates to poultry feeds, in particular to a heat stress resistant meat duck feed. The meat duck feed comprises, by mass of air dry matter, 0-2% of fish meal, 0-10% of soybean meal, 0-10% of rapeseed meal, 0-10% of cottonseed meal, 5-10% of distillers dried grains with soluble (DDGS), 0-15% of full-fat rice bran, 10-45% of corn, 0-40% of wheat, 0.9-2% of calcium carbonate, 0.5-1% of calcium hydrogen phosphate, 1-3% of soybean oil and 2% of premix and additive. In addition, 50-70kg of Chinese herbal medicine liquid is added into feed per ton during mixing. The invention has the advantages that a traditional herb tea theory is used for constant optimization and match, production technology is improved, animal feed intake and growth performance can be improved, and heat stress can be relieved; and feedstuff and Chinese herbal medicine accord with health and national standards of feeds and have no harmful effects on nutritional values of meat duck.

Description

technical field [0001] The invention relates to a poultry feed, in particular to a heat stress-resistant meat duck feed. Background technique [0002] The most suitable ambient temperature for meat ducks is 16-22°C. When the ambient temperature is higher than 28°C, heat stress syndrome will occur in meat ducks, and metabolism and normal physiological functions will be disordered. For every increase of 1°C, the feed intake of meat ducks will decrease by 1.5%. When the temperature exceeds 32°C, the feed intake of meat ducks will drop sharply. At 1°C, the feed intake of meat ducks decreased by 5%. [0003] At present, Guangdong Province, the main breeding area for meat ducks, has a summer temperature exceeding 30°C for up to 5 months. The feed intake of meat ducks in high temperature seasons decreases by an average of 20%, and the average slaughter weight of meat ducks decreases by 0.25-0.5kg / piece. The average survival rate is reduced by 5-10%. Due to the reduction in final ...
