Problems solved by technology

Therefore, a large number of drugs such as antibiotics, growth-stimulating hormones, and hormones are used in chicken production to reduce the fat content in the carcass, which not only aggravates the decline in chicken quality and flavor, but also brings harm to human health due to drug residues and side effects. great harm

Embodiment 1

[0018] Collect wheat straw, dry it in the sun, carbonize it under oxygen-limited and relatively low temperature conditions (<500°C, generally 350-500°C), and crush it through a 60-mesh sieve.

[0019] The physical and chemical properties of the biochar additive prepared in Example 1 are shown in Table 1 and Table 2:

Embodiment 2

[0024] The impact of embodiment 2 on broiler production performance

[0025] Using the biochar feed additive obtained in Example 1, the test adopted a single factor complete random grouping design. 100 healthy 22-day-old Ross broilers were randomly divided into 4 groups, with no difference in initial body weight, CK (basic diet), low dose (1% feed additive and basic diet), medium dose (5% feed additive and Basic ration) and high dose (10% feed additive and basal ration); before the test, clean and disinfect the chicken coop, trough, water feeder, etc. The litter is raised flat, the temperature of the chicken house is 20-22°C, natural lighting is used, and the chicken house is kept ventilated, dry and hygienic. The test period is 33 days. During the experiment, free access to food and water, carefully observe the condition of the flock, record the daily feed intake and the number of dead pans. Fasted for 12 hours at the end of the test, weighed, and calculated its death rate...

Embodiment 3

[0030] The impact of embodiment 3 on broiler slaughter performance

[0031] Adopt the biochar feed additive that embodiment 1 obtains, establish group and content with embodiment 2, fast 12h when test finishes, weigh, calculate full evisceration rate, leg muscle rate, chest muscle rate and abdominal fat rate; Calculate The formula is as follows, and the results are shown in Table 4;

[0032] Eviscerated rate (%) = Eviscerated mass / living body mass × 100%;

[0033] Leg muscle rate (%) = leg muscle mass / eviscerated mass × 100%;

[0034] Breast muscle rate (%) = chest muscle mass / eviscerated mass × 100%;

[0035] Abdominal fat rate (%) = abdominal fat mass / eviscerated mass × 100%;

Abstract

The invention discloses a chicken feed capable of lowering blood fat and promoting production property of broiler chickens as well as a feed additive. The chicken feed is obtained by adding 1%-10% of the biomass charcoal feed additive in basic ration of chickens. The biomass charcoal feed additive is formed through carbonizing sundried wheat straws under oxygen limited and relative low-temperature conditions, crushing the carbonized wheat straws and sieving the crushed wheat straws to 60-100 meshes. The chicken feed provided by the invention can promote the production property of broiler chickens, lower abdominal fat percentage and feed conversion ratio, and especially lower the content of total cholesterol and triglyceride of broiler chickens, overcomes the defect that antibiotics and chemical synthesis additives have residues and side effects, avoids environment pollution caused by straw combustion, widens the utilization approach of biomass charcoal, and turns waste in wealth. The feed additive provided by the invention is an environment-friendly and safe feed additive which has no side and toxic effect and has no drug residue, and has wide market prospect and favorable economical and social benefits.

Description

technical field [0001] The invention belongs to the field of animal husbandry and agricultural resources, and relates to a chicken feed and a feed additive capable of reducing the blood fat of broilers and promoting the production performance of broilers. Background technique [0002] With the rapid development of my country's fast food industry, chicken has increasingly become an important part of human meat consumption. Many studies have shown that a large intake of animal fat will seriously affect human health, especially the incidence of cardiovascular diseases will increase significantly. Therefore, a large number of drugs such as antibiotics, growth-stimulating hormones, and hormones are used in chicken production to reduce the fat content in the carcass, which not only aggravates the decline in chicken quality and flavor, but also brings harm to human health due to drug residues and side effects. Great harm. At present, with the improvement of people's living standa...
