Problems solved by technology

Past studies have shown that an important reason for the low utilization efficiency of feed protein is that a large amount of amino acids are oxidized and metabolized in the body for energy supply

experiment example 1

[0027] Experimental example 1: Effects of adding large doses of nicotinamide to the diet on nitrogen emission and growth performance of pigs

[0028]1. The effect of different levels of niacinamide in the diet on the nitrogen emission of pigs

[0029] 1. Experimental design: Select 5 barrows with similar weight (40±1kg) and good health (hybrid breed: Du × long × large), and carry out the nitrogen balance research of the following diets according to the 5 × 5 Latin square experimental design .

[0030] Control group: 16% CP+30mg / kg nicotinamide;

[0031] Experimental group 1-1: 16% CP+60mg / kg nicotinamide;

[0032] Experimental group 1-2: 16% CP+120mg / kg nicotinamide;

[0033] Experimental group 1-3: 16% CP+240mg / kg nicotinamide;

[0034] Experimental group 1-4: 16% CP+360 mg / kg nicotinamide.

[0035] Among them, CP refers to crude protein. The amount of nicotinamide added is calculated on the basis of complete feed (diet) (that is, 30-360 mg per kg of complete feed), and ...

experiment example 2

[0075] Experimental Example 2: Effects of dietary supplementation of large doses of niacin on nitrogen emission and growth performance of pigs

[0076] After carrying out the effects of different levels of nicotinamide in the diet on nitrogen emission and growth performance of pigs, we continued to carry out the effects of nicotinic acid, a structural and functional analogue of nicotinamide, on nitrogen emission and growth performance of pigs. The main results are as follows: (1) When the supplementation level of niacin increased from 60mg / kg to 360mg / kg (based on complete feed), the nitrogen emission reduction effect of pigs gradually reached the best. The nitrogen emission of pigs decreased slightly with the increase of supplementation amount; when the supplementation amount increased from 1800mg / kg to 1920mg / kg, the nitrogen emission of pigs did not decrease but increased. (2) Adding 360mg / kg niacin to normal diets or low-protein diets can reduce pig nitrogen emission reduc...

Abstract

The present invention relates to the technical field of livestock breeding, and discloses a feed containing a large dose of nicotinamide or nicotinic acid, the feed comprises a daily ration feed and a functional agent, the functional agent is nicotinamide or nicotinic acid, and the addition amount of the functional agent is 60-1800 mg / kg on the basis of a complete feed and 20-600 mg / L on the basis of drinking water. In livestock and poultry breeding, the compound can be used as a livestock and poultry breeding nitrogen emission reduction agent and a livestock and poultry breeding growth promoter, can eliminate negative effects of low-protein daily ration on livestock and poultry nitrogen deposition and growth performance, can effectively reduce oxidative metabolism of amino acid, and improves the proportion of amino acid for synthesizing protein. Finally, the purposes of improving the utilization efficiency of feed protein and reducing nitrogen emission are achieved.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a feed containing large doses of nicotinamide or nicotinic acid and its application in pig production. Background technique [0002] In the past 40 years, my country's animal husbandry has developed steadily and rapidly, but it has also brought about a series of problems, among which the lack of protein feed raw materials is particularly prominent. There is a huge gap between the production and demand of protein feed resources in my country. In 2020, 100.33 million tons of soybeans will be imported, while the domestic production of soybeans is less than 20 million tons, and the dependence on soybeans is close to 85%. In addition, the environmental pollution caused by nitrogen emissions cannot be ignored. The average utilization efficiency of feed protein by livestock and poultry is only about 50%. The annual nitrogen emissions from livestock and poultry farming in my co...
