Problems solved by technology

Domestic Zhang Yongqing et al. (2007), Qiao Jianguo et al. (2008) reported the effects of exogenous nucleotides on the production performance, antioxidant function and small intestine development of weaned piglets. Some foreign researchers (Stein, 2004; Bustamante et al., 2004 ; Martinez-Puig et al., 2007) have studied the effects of nucleotides on the growth and immune function of weaned piglets, but the results are inconsistent
Moreover, the ratio of nucleotides may directly affect the use of nucleotides, but there are few research reports on the ratio of nucleotide monomers

Embodiment 1

[0022] A nucleotide feed additive for weaned piglets: using Torulopsis globosa as raw material, the extracted ribonucleic acid is subjected to enzymolysis, and then the enzymolysis solution is directly spray-dried to obtain four kinds of nucleotides AMP, CMP, GMP, The mixed nucleotides of UMP, the mixed nucleotides contain the following components by weight percentage: 50% mixed nucleotides, 18% crude protein, 4% crude fat, 20% ash, and 8% water. Detect the content of four nucleotides, on this basis, add an appropriate amount of pure single nucleotides, so that the weight ratio between the four nucleotides is: adenylic acid: cytidylic acid: guanylic acid: uridylic acid =0.98:0.5:1.2:1.0, in this additive, the total content of nucleotides is finally 66.6%.

Embodiment 2

[0024] A nucleotide feed additive for weaned piglets: using Saccharomyces cerevisiae as raw material, enzymatically hydrolyzing the extracted ribonucleic acid, and then directly spray-drying the enzymolyzed solution to obtain four kinds of nucleotides AMP, CMP, GMP, UMP The mixed nucleotides contain the following components by weight percentage: 42% mixed nucleotides, 18% crude protein, 6% crude fat, 25% ash, and 9% moisture. Then add an appropriate amount of pure mononucleotide on its basis, so that the weight ratio between the four nucleotides is: adenylic acid: cytidylic acid: guanylic acid: uridylic acid=1.2:0.7:1.5:1.3 , in this additive, the total content of nucleotides is finally 59.4%.

Embodiment 3

[0026] A nucleotide feed additive for weaned piglets: using Candida utilis as a raw material, enzymatically hydrolyzing the extracted ribonucleic acid, and then directly spray-drying the enzymatic solution to obtain four kinds of nucleotides AMP, CMP, Mixed nucleotides of GMP and UMP, the mixed nucleotides contain the following components by weight percentage: 60% mixed nucleotides, 14% crude protein, 2% crude fat, 19% ash, and 5% moisture. , and then add an appropriate amount of pure mononucleotide on its basis, so that the weight ratio between the four nucleotides is: adenylic acid: cytidylic acid: guanylic acid: uridylic acid=1.0:0.3:1.1: 0.7, in this additive, the total content of nucleotides is finally 67.3%.

Abstract

The invention discloses a weaned piglet nucleotide feed additive. The weaned piglet nucleotide feed additive comprises, by weight, 0.8 to 1.3 of adenosine monophosphate 5'-AMP, 0.3 to 0.8 of cytidine monophosphate 5'-CMP, 1.1 to 1.5 of guanosine monophosphate 5'-GMP and 0.7 to 1.4 of uridine monophosphate 5'UMP. The invention further discloses a preparation method and an application of the feed additive. According to the weaned piglet nucleotide feed additive, stress reaction of weaned piglets can be effectively relieved, the piglet grazing rate and the feed utilization efficiency are improved, the oxidation resistance and the immune function of weaned piglets are improved apparently, the organic resistance is enhanced, and accordingly, important significances are provided for modern scientific, intensive and large-scale pig production.

Description

technical field [0001] The invention relates to a feed additive for livestock, in particular to a feed additive for weaned piglets. Background technique [0002] In modern intensive and large-scale pig production, piglet early weaning technology is a key link in the pig industry. The research and application of feed formula for early weaned piglets is directly related to the growth and future production performance of weaned piglets. In my country, compared with the traditional weaning age of piglets, it is generally called early weaning at the age of 21 to 35 days, and weaning before the age of 21 is called super early weaning. However, early weaned piglets, especially ultra-early weaned piglets, face problems such as immature digestive tract, poor gastrointestinal function, immune insufficiency, and low disease resistance, and weaning is also related to the physiological, psychological, environmental and nutritional status of piglets. These will cause piglet allergies, de...
