Description
Technical Field
The invention belongs to the technical field of feed processing, relates to a preparation method of yellow-feather broiler feed, and particularly relates to feed for improving the muscular stomach development of yellow-feather broilers, and a preparation method and an application thereof.
Background
The gizzard of the chicken contains rich nutrient elements, protein, vitamin A, vitamin E, carotene, various trace elements and the like. The components contained in the gizzards of the chickens mainly comprise gastric hormone, keratin amino acid and the like. The gizzard has the functions of increasing the secretion of gastric juice of a human body and the digestion of intestines and stomach, so that the emptying speed of the intestines and stomach is increased, and meanwhile, the gizzard is also the best food for supplementing iron. The added value of the gizzards in the chicken product is relatively high, the market demand is large, the size of the gizzards obviously influences the purchase desire of consumers and the price-overflow level of the gizzard product.
The fast and large yellow-feather broilers are used as excellent broiler varieties, through breeding for many years, the fast and large broilers are typical grain-saving animals, the feed conversion rate is obviously higher than that of other livestock and poultry varieties, the fast yellow-feather broilers grow fast, the fast and large broilers have wide markets, and the fast and large broilers have larger development potential from the income structure and can be selected as production sources of high-quality gizzard products.
Most of the existing technical schemes capable of promoting the development of the muscular stomach are suitable for laying hens, but the broiler chicken has the characteristic of susceptibility to glandular stomach and muscular stomach ulcers and inflammation in the growth process, and the incidence condition is far higher than that of the laying hens. Although the technical scheme of crushing the feed to a specific granularity is adopted, the feed with different granularities also has great influence on the production performance of animals. Too large particles can cause lower growth speed and reduce the production performance of the broiler chickens, and the too large particles cannot be well utilized by the broiler chickens. However, the particle size is too fine, the stimulation to the gastrointestinal peristalsis is insufficient, the muscular stomach atrophy, the small intestine hypertrophy, the pH value of intestinal chyme is reduced, the bacterial fermentation is enhanced, the amount of volatile fatty acid is increased, the appetite is affected, and the production performance is reduced.
And the selection of the time for stimulating the development of the muscular stomach is also more important, the prior technical scheme is to stimulate the development of the muscular stomach at the chick stage, and the grinding behavior and the movement rule of the muscular stomach are as follows: the cyclic abrasion starts with a thin muscle contraction followed by pylorus opening and a severe peristaltic contraction of the duodenum; after the duodenum contracts, a pair of developed and thick lateral muscles begin to contract immediately, one part of stomach chyme is squeezed into the duodenum, and the other part enters the glandular stomach; as developed lateral muscles relax, the glandular stomach begins to contract, and chyme flows back to the muscular stomach; the glandular stomach is a unique part in front of the muscular stomach and can secrete pepsinogen and hydrochloric acid, chyme flows back to the glandular stomach when the muscular stomach contracts, more pepsinogen and hydrochloric acid enter the chyme, the feed intake of chickens is increased, and therefore the secretion amount of glandular stomach liquid and the reflux amount of chyme are increased, and the enlargement of the glandular stomach is caused. The stimulation of the early muscular stomach development can cause the diseases of glandular stomach and muscular stomach to increase, and the feed reward is influenced.
Therefore, how to provide the feed which can meet the nutritional requirements of the fast-growing yellow-feathered broilers without influencing the normal growth of the fast-growing yellow-feathered broilers, can reasonably stimulate the development of glandular stomachs and promote the commodity added value of the fast-growing yellow-feathered broilers has great potential development value for the development of the fast-growing yellow-feathered broilers industry.

Feeding tests are carried out in a yellow-feather broiler breeding colony house of the Xinjiang Taiquan group, and ground padding is adopted for flat breeding, the technical scheme provided in the third to seventh embodiments of the invention is that the test 1-5 groups are adopted, a contrast group is fed by using conventional fast large yellow-feather broiler granulated feed sold in the market, 50 fast large yellow-feather broilers with similar weights in 50 days are adopted in each treatment, the feeding management and conditions of the early stages of the fast large yellow-feather broilers are consistent, the fast large yellow-feather broilers are fed and drunk freely, and feeding and immunization are carried out according to conventional feeding operation rules and immunization programs. The test period is 50-70 days old, and the temperature and humidity are recorded at 8: 00 and 14: 30 every day. During the test period, the health and mental status of the chickens were observed daily and the number of deaths was recorded.
2. Measurement index
2.1, Productivity
(1) Feed intake
And (4) accurately recording the daily feed consumption, weighing the feed when dead chickens appear, and calculating the total feed consumption. The growth performance index was calculated as follows:
average daily food intake (ADFI, g) ═ total material consumption/(days x)
(2) Initial body weight and final body weight
The weight of the test chicken on empty stomach was measured by cutting off the feed water 22: 00 the day before the age of 50 days and the age of 70 days, and weighing the weight of the test chicken on empty stomach in the 2 nd day 9: 00 by taking the repetition as the unit.
2.2, intestinal tract index
Selecting 15 chickens at 50 days and 70 days according to the average weight repeatedly, bleeding to death, taking out intestinal tracts, washing the glandular stomach and the muscular stomach with distilled water to remove chyme in the chickens, sucking the chickens with filter paper, weighing and measuring the glandular stomach and the muscular stomach, and calculating the relative weight of the muscular stomach by the following calculation formula:
relative weight (%) of muscular stomach (fresh weight (g)/live weight (g)) x 100;
the final myogastric relative weight levels for each group were averaged.
2.3 anatomical changes in the muscle and glandular stomachs
After a 70-day-old slaughter, the glandular and muscular stomachs were externally observed and compared. Then, the glandular stomach and the muscular stomach are dissected, and the change of the papilla of the glandular stomach and the thickness of the wall of the glandular stomach are observed.
3. Statistics and analysis
Experimental data was analyzed for variance using SPASS. The level of statistical significance was P < 0.05. The experimental data are expressed as (mean ± sem).
4. Results and analysis
