Problems solved by technology

Studies have shown that if the crude protein in the pig diet is reduced by 1 percentage point, the nitrogen discharge in the feces and urine can be reduced by 8% to 13%. However, under the condition of low nitrogen emission diet, the carcass quality of fattening pigs decreased due to excessive fat deposition, and the drip loss of finishing pigs increased after slaughter

Abstract

The invention relates to a mixed feed for improving fattening pig carcass quality under low-nitrogen-discharging daily ration ; the feed is prepared from the components by the weight percentage: 50-75% of corn, 8-20% of soybean meal, 5-15% of cottonseed proteins, 1-15% of wheat bran, 5-15% of rice bran, 0.5-1.5% of soybean oil, 0.5-1.5% of calcium hydrogen phosphate, 0.5-1.5% of calcium carbonate, 0.5-1.5% of lysine sulfate, 0.1-1.0% of threonine, 0.01-0.05% of methionine, 0.01-0.05% of tryptophan, 0.1-1.0% of sodium chloride, 0.1-1.0% of betaine, 0.1-1.0% of sodium bicarbonate, 0.01-0.1% of calcium propionate, 0.01-0.1% of 66% ethoxy quinoline, 0.01-0.1% of a microecological preparation, and 0.5-2% of a compound premixed feed for fattening pigs. The mixed feed has effects on pig growth performance, pork quality, and metabolism of lipids and proteins in blood, and also plays positive roles in adjusting the distribution of pork fat, improving the fattening pig carcass quality, enhancing the flavor of pork, reducing nitrogen emissions and protecting the environment.

Description

technical field [0001] The invention relates to the technical field of animal nutrition and feed, in particular to a compound feed for improving carcass quality of fattening pigs under a low-nitrogen discharge diet. Background technique [0002] my country's protein feed resources are heavily dependent on foreign imports. In 2014, 73 million tons of soybeans were imported, while my country's annual output of soybeans was about 10 million tons. The shortage of protein feed resources has seriously restricted the development of my country's animal husbandry. The environmental protection caused by nitrogen emissions in pig breeding This problem has attracted the attention of the whole society. Studies have shown that if the crude protein in the pig diet is reduced by 1 percentage point, the nitrogen discharge in the feces and urine can be reduced by 8% to 13%. However, under the condition of low nitrogen emission diet, the carcass quality of fattening pigs decreased due to exces...
