Embodiment 1

[0019] Embodiment 1, the preparation of special mulberry feed 1 for yellow chicken

[0020] Adopt the preparation method of the special mulberry feed for yellow chickens involved in the instruction manual, the pre-feed per kilogram is composed of 553 grams of corn, 322 grams of soybean meal, 50 grams of dry powder of mulberry stems and leaves, 25 grams of soybean oil, and 50 grams of additive premix; The mid-term feed consists of 584 grams of corn, 281 grams of soybean meal, 50 grams of mulberry powder, 35 grams of soybean oil, and 50 grams of additive premix; each kilogram of late feed consists of 632 grams of corn, 218 grams of soybean meal, 50 grams of mulberry powder, and 50 grams of soybean oil. gram and 50 grams of additive premix. Accurately weigh each component according to the above formula, mix and stir evenly, and prepare mulberry feed 1 for each period of yellow chicken.

Embodiment 2

[0021] Embodiment 2, the preparation of special mulberry feed 2 for yellow chickens

[0022] Adopt the preparation method of special-purpose mulberry feed for yellow chickens involved in the instruction manual. Each kilogram of pre-feed consists of 474 grams of corn, 287 grams of soybean meal, 150 grams of mulberry powder, 39 grams of soybean oil, and 50 grams of additive premix; It consists of 512 grams of corn, 241 grams of soybean meal, 150 grams of mulberry powder, 47 grams of soybean oil, and 50 grams of additive premix; each kilogram of late feed consists of 561 grams of corn, 177 grams of soybean meal, 150 grams of mulberry powder, 62 grams of soybean oil, The additive premix consists of 50 grams. Accurately weigh each component according to the above formula, mix and stir evenly, and prepare mulberry feed 2 specially for yellow chickens of each period.

Embodiment 3

[0025] Embodiment 3, investigate respectively the difference in the effect of raising the ratio of polyunsaturated fatty acids in chicken meat by the special mulberry feed 1 and 2 prepared by Example 1-2 and the feed a prepared by the comparative example

[0026] A single factor completely randomized experimental design was adopted. A total of 360 healthy 1-day-old rapid-type yellow chickens with similar body weight were selected and randomly divided into 4 treatment groups, each treatment group had 6 replicates, and each replicate had 15 chickens. Broilers in 4 treatment groups were fed feed a (control group, this feed was prepared in the comparative example), full-term feeding containing mulberry feed 1 (full-term 5%, this feed was prepared in Example 1), and full-term feeding Feeding mulberry feed 2 (full period 15%, this feed was prepared in Example 2), feeding mulberry feed 2 at the age of 14-49 days, and feeding feed a (stage 15%) at other times. The feed formulation an...

Abstract

The invention discloses a feed capable of increasing the proportion of polyunsaturated fatty acid in chicken meat specially for yellow chickens, which comprises folium broussonetiae papyriferae as a key component. The feed is prepared from the following components in parts by mass (on dry matter basis): 48 to 65 parts of corns, 15 to 28 parts of soybean meal, 5 to 20 parts of folium broussonetiae papyriferae powder, 2.5 to 6 parts of soybean oil and 5 parts of an additive premix. Compared with a conventional corn-soybean meal feed, the feed for the yellow chickens has the advantages that the proportion of the polyunsaturated fatty acid in the chicken meat of the yellow chickens can be remarkably increased, and relatively great influence on the productivity of the yellow chickens is avoided.

Description

technical field [0001] The invention relates to a special mulberry feed for yellow chickens which can increase the proportion of polyunsaturated fatty acids in chicken meat and a preparation method thereof. Background technique [0002] Paper mulberry is a deciduous tree with strong adaptability, widely distributed in most provinces and autonomous regions of my country. Strudel leaves are rich in protein, amino acids, nitrogen-free extracts, calcium, phosphorus and various trace elements, among which the crude protein content is as high as 18%-24%, which is an unconventional feed resource with great development value. The study found that adding mulberry leaves to the diet can reduce the weight gain cost of pigs. Due to the complex structure of the leaf protein and the high content of crude fiber, it is difficult for monogastric animals to digest and absorb. To solve this problem, researchers use microbial fermentation technology to improve the digestion and utilization ef...
