Description
Technical Field
The invention relates to a broussonetia papyrifera feed special for yellow chickens and a preparation method thereof, wherein the broussonetia papyrifera feed is used for improving the proportion of polyunsaturated fatty acids in chicken.
Background
The paper mulberry is a deciduous tree with strong adaptability and is widely distributed in most provinces of China. The broussonetia papyrifera leaves contain rich protein, amino acid, nitrogen-free extract, calcium, phosphorus, various trace elements and the like, wherein the content of crude protein is up to 18-24 percent, and the broussonetia papyrifera leaves are an unconventional feed resource with great development value. Researches show that the weight gain cost of the pork pigs can be reduced by adding broussonetia papyrifera leaves into daily ration. Because the protein structure of the broussonetia papyrifera leaves is complex, the crude fiber content is high, and monogastric animals are difficult to digest and absorb. To solve the problem, researchers adopt a microbial fermentation technology to improve the digestion and utilization efficiency of the broussonetia papyrifera leaves, but the fermentation process increases the cost of the broussonetia papyrifera leaves and influences the large-scale application of the broussonetia papyrifera leaves.

2. Results of the experiment
2.1 Effect of Broussonetia papyrifera powder on yellow chicken production Performance
TABLE 1 influence of feed supplemented with Broussonetia papyrifera powder on the performance of yellow chicken (0-63 days old)
As can be seen from Table 1, compared with the conventional corn bean pulp type daily ration, feeding 5-15% of paper mulberry powder daily ration has no significant influence on the weight, daily gain and feed intake of yellow-feathered broilers of 63 days old (P is more than 0.05); feeding 15% paper mulberry powder daily ration only reduced the feed conversion efficiency of 63-day-old yellow chickens (P < 0.05). Shows that the feeding of the broussonetia papyrifera daily ration has little influence on the production performance of the yellow chickens.
2.2 Effect of Broussonetia papyrifera powder on the fatty acid composition of the breast muscle of yellow chickens
Table 2 influence of feed supplemented with broussonetia papyrifera powder on the fatty acid composition of breast muscle of yellow chicken (%)
As can be seen from table 2, feeding 5-15% of the broussonetia papyrifera powder did not affect the ratio of saturated fatty acids and unsaturated fatty acids in the chest muscle fat (P ═ 0.67), but affected the ratio of monounsaturated fatty acids and polyunsaturated fatty acids in the unsaturated fatty acids (P ═ 0.03, <0.01), wherein the ratio of monounsaturated fatty acids in each group fed with the broussonetia papyrifera powder was significantly lower than that in the control group, and the ratio of polyunsaturated fatty acids was significantly higher than that in the control group (P < 0.05).
Feeding broussonetia papyrifera powder significantly affected the ratio of omega 3 and omega 6 fatty acids in pectoralis fat (P0.01, 0.02), with 15% stage group omega 3 fatty acids significantly higher than control group (P <0.05) and full stage and stage 15% group omega 6 fatty acids significantly higher than control group (P < 0.05). Feeding broussonetia papyrifera powder significantly affected the proportion of DHA in the omega 3 fatty acids of the pectoralis muscle (P ═ 0.04), did not affect the proportion of EPA (P ═ 0.57), and affected the trend of the proportion of arachidonic acid in the omega 6 fatty acids (P ═ 0.07), wherein the proportion of DHA in the pectoralis muscles of yellow chickens in 15% of the total period and 15% of the stage group was significantly increased (P <0.05), and the proportion of arachidonic acid in 15% of the total period was significantly higher than that in the control group (P < 0.05).
