Description
Technical Field
The invention belongs to the field of feeds, relates to a feed formula, and particularly relates to a yellow-feather broiler feed capable of improving meat quality with high efficiency and low cost and application thereof.
Background
With the rapid development of modern broiler breeding industry in China, the problems of shortage of conventional feed resources, rising of feed raw material price and the like are increasingly highlighted, and the development of non-grain feed is an important way for relieving the shortage of feed resources, reducing the feeding cost and improving the economic benefit. And the rapeseed meal, the cottonseed meal and the corn DDGS unconventional raw materials have high protein content and have higher utilization value as protein sources. However, the unconventional feed is unbalanced in nutrition, corn processing byproducts such as corn DDGS (distillers dried grains with soluble) are rich in non-starch polysaccharides and polyunsaturated fatty acids, and miscellaneous meal such as rapeseed meal and cottonseed meal contain some toxic substances and anti-nutritional factors, so that the growth of broiler chickens is adversely affected due to improper use, an oxidation balance system of an organism is damaged, the quality, flavor and safety of chicken are reduced, and the like. In recent years, research reports have shown that probiotics can promote the digestion and absorption of nutrients, improve the intestinal micro-ecological system of livestock and poultry, and have the potential of antagonizing and eliminating food safety hazard factors such as phytotoxin, microbial toxins, pathogenic bacteria and the like; the natural plant extract and the antioxidant have obvious effects on relieving the oxidative stress of organisms, reducing lipid peroxidation, increasing the content of intramuscular fat and improving the quality of chicken.
At present, in intensive breeding of modern broiler chickens, yellow-feather broiler chicken feed is mainly corn-soybean meal type feed, and the efficient utilization technology of unconventional feed is still relatively short. Therefore, the unconventional feed of rapeseed meal, cottonseed meal and corn DDGS is reasonably used for replacing soybean meal and fish meal, and the toxic and side effects of the unconventional feed are relieved through natural plant extracts and composite probiotics, so that the feed has very important significance for reducing the feed cost, improving the chicken quality and stabilizing the intestinal flora.

The feed is mixed and then granulated, the granulation temperature is 75 ℃, and the diameter of the granules is 3 mm.
The feed is suitable for fast-growing yellow-feather broilers.
Test materials and methods: dividing 600 large yellow-feather cocks of 42 days old with average weight into 2 treatment groups randomly, repeating each group for 6 times, feeding 50 chickens in each repeated fence on the ground, feeding basic feed (control group) and test feed (test group) respectively, finishing the test when the chickens are fed to 63 days old, and the test period is 21 days totally. During the test period, the test chicken freely eats and drinks water, and other feeding management is carried out according to the conventional feeding management rules. The test material preparation of each treatment group was carried out with reference to the Standard for Chicken Breeding (NY/T33-2004). The daily feed intake and feed remaining in each column were recorded during the test. When the test is finished, after venous blood of yellow feather broilers is collected, the liver and the pectoral muscle tissues of the test chickens are slaughtered and taken for index analysis.
Average daily food intake: the weight of feed taken by each chicken per day during the test period.
Daily gain: (63-42 days old test chicken body weight)/test days.
The material weight ratio is as follows: daily feed intake and daily gain.
When test chickens (63 weeks old) are tested, 2 test chickens close to the average weight are repeatedly selected for each test, blood is collected in a wing vein by 5mL, the test chickens are kept standing for 30min, then the blood plasma is centrifuged at 3500rpm for 10min, the blood plasma sample is separated, and the contents of total bile heme, Total Protein (TP), Albumin (AP), reduced Glutathione (GSH), oxidized glutathione (GSSG) and Malondialdehyde (MDA) in the blood plasma to be tested are stored at the temperature of-80 ℃; activity biochemical indexes of Glutamic Oxaloacetic Transaminase (GOT), Glutamic Pyruvic Transaminase (GPT), total antioxidant capacity (T-AOC), total superoxide dismutase (T-SOD) and glutathione peroxidase (GSH-Px).
And (4) after blood collection, performing blood drawing and slaughtering on the jugular part of the test chicken. Removing feather, foot skin and toe shell, weighing to obtain carcass weight, dissecting liver (gallbladder), spleen, bursa of fabricius and thymus, removing connective tissue and fat, weighing to obtain semi-bore weight, removing head, removing feet, removing heart, and weighing to obtain full-bore weight.
Two lateral pectoralis muscles are taken for analyzing the meat quality and the flavor index, and the specific steps refer to the chicken quality determination steps proposed by animal science research institute of agricultural academy of sciences in Guangdong province.
Pathological analysis of liver tissue: the fixed liver tissue sample is embedded in paraffin, and the prepared section is observed under a reverse microscope to observe the pathological change of the tissue by adopting a conventional hematoxylin-eosin staining method, and is recorded and photographed.
The test results are shown in tables 1-5 and FIGS. 1 and 2.
