Abstract
The invention relates to a feed additive for broilers. The feed additive is prepared from the following raw materials in parts by weight: 5-12 parts of artichokes, 3-8 parts of Chinese magnoliavine fruits, 2-6 parts of lotus leaves, and 5-12 parts of dried orange peel. According to the feed additive for broilers, provided by the invention, the additive quantity of products is small, and the feed additive has multiple functions, and not only can increase weight, promote growth, improve the immune function of the broilers, but also can improve the quality of chicken meat. The feed additive disclosed by the invention is added to a feed for the broilers, so that the feed additive has the effects of promoting the growth of the broilers, increasing the feed conversion rate, reducing the feed-gain ratio, improving the immunity of the broilers and improving the quality of the broiler meat, and is a safe and effective feed additive.
Description
Technical field
The invention belongs to animal feed additive field, especially relate to a kind of broiler chicken feed additive.
Background technology
Animal feed additive improving breeding performonce fo animals, ensure animal health, save feeding cost, improve product quality etc. in there is remarkable effect. Chinese herbal feed additive is a big class of feed additive kind apoplexy due to endogenous wind, compared to Antibiotic Additive, hormones additive etc., has natural, the functional diversity in source, the advantage such as safe and reliable. In prior art, broiler growth growth promotion, diseases prevention and treatment are paid close attention to more, and ignores the change of chicken meat quality. , there is the defect that Carnis Gallus domesticus meat is bad, taste is not good enough in existing broiler product, although achieve certain effect in weightening finish growth promotion, but the feedback according to consumer.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes the deficiencies in the prior art, it is provided that a kind of growth promotion that can increase weight, improve the broiler chicken feed additive of Carnis Gallus domesticus meat.

Application Example
Below by way of to clinical zoopery and standardized farm breeds, beneficial effects of the present invention is described. Main with broiler chicken for object of study, investigate the product of the present invention impact on broiler chicken weightening finish, lipid metabolism and immune function.
One, material and method
1, laboratory animal and packet
800 1 age in days Ai Wei bacterial context chicks are randomly divided into 8 groups; 1st group is blank group, feeds basis grain ration; 2nd group is antibiotic matched group, feeds basis grain ration+50mg*kg-1Chlortetracycline; 3rd group feeds basis grain ration+1.0g*kg-1Embodiment 1 product, the 4th group feeds basis grain ration+1.33g*kg-1Embodiment 1 product; 5th group feeds basis grain ration+1.0g*kg-1Embodiment 2 product, the 6th group feeds basis grain ration+1.33g*kg-1Embodiment 2 product, the 7th group feed basis grain ration+1.0g*kg-1Embodiment 3 product, the 8th group feeds basis grain ration+1.33g*kg respectively-1Embodiment 3 product.
2, test feed and feeding and management
Test feed is daily ration based on Corn-soybean powder, tests whole chicken employing 4 layers and raises in cages, and infrared lamp heats, carry out feeding and management routinely, 24h illumination, free choice feeding and drinking-water. every day viewing test chicken the mental status, diet and defecation and death condition, and make a record.
3, study index and method
(1) gain in weight: weigh at 35,56 ages in days respectively, calculates total augment weight and average daily gain. Experimental data represents with x ± S, analyzes by SPSS software statistics, and the comparison t of two means checks.
(2) impact on broiler lipid metabolism and immune function: test chicken carries out ND-HI titer respectively at 7 and 28 ages in days, respectively at 21 and 42 ages, each test chicken repeating to select 1 close to average weight, butcher, gather whole blood respectively and separate serum, measuring indices.
Serum lipid metabolism index: adopt the test kit that the Shanghai biological company limited of enzyme connection produces to measure serum triglycerides, T-CHOL, HDL-C and low-density lipoprotein cholesterol content respectively.
Immune Organs Index: taking out thymus, spleen and fabricius bursa after butchering, put in normal saline, reject crimson blood and fascia, blot with filter paper and weigh, calculate thymus index, index and spleen index, bursal index, the share accounting for every kg body weight with immune organ fresh weight represents.
Periphery blood T lymphocyte percentage rate (ANAE+%): adopt whole blood, smear, adopts α-naphthyl acetate esterase Determination Staining periphery blood T lymphocyte percentage rate.
ND_HI antibody titre: adopt the U-shaped plate reaction method of hemagglutination test (HA test) and hemagglutination inhibition test (HI test) 96 hole to measure newcastle blood clotting and suppress (ND-HI) antibody titer.
Experimental result adopts SPSS software to carry out statistical analysis, and multiple comparisons adopts Duncan ' s method.
4, result and discussion
(1) gain in weight
Result is as shown in table 1, and at 35,56 ages in days, 3-8 group (test group) daily gain is higher than the 1st group (blank group) (P < 0.05), illustrates that product of the present invention can remarkably promote the weightening finish of broiler chicken.
(2) impact on broiler lipid metabolism
Result is as shown in table 2, in serum triglycerides, when 3 week old, difference not notable (P > 0.05) between each group, when 6 week old, experiment 3-8 group is substantially less than blank group and antibiotic matched group (P < 0.05). In T-CHOL, when 3 week old and 6 week old, experiment 3-8 group is all substantially less than blank group and antibiotic matched group (P < 0.05). As can be seen here, each test group all can reduce serum triglycerides and serum total cholesterol content in various degree.
As shown in Table 3, in serum LDL cholesterol, when 3 week old and 6 week old, experiment 3-8 group compares with blank group and antibiotic matched group, serum low-density LP content (P > 0.05) on a declining curve. In serum High Density Lipoprotein Cholesterol, when 3 week old, difference not notable (P > 0.05) between each group, when 6 week old, experiment 3-8 group is substantially less than blank group and antibiotic matched group (P < 0.05). As can be seen here, each test group all can reduce serum low-density LP content in various degree and improve serum high-density LP content.
(3) impact on broiler immunologic function
As shown in Table 4, when 3 week old, experiment 3-8 group thymus index is significantly higher than blank group (P < 0.05), compares with antibiotic group and slightly increases, but difference inconspicuous (P > 0.05). When 6 week old, experiment 3-8 group thymus index is significantly higher than blank group and antibiotic group (P < 0.05). 3,6 week old time, between each group, index and spleen index is without significant difference (P > 0.05). 3,6 week old time, experiment 3-8 group bursal index is all remarkably higher than blank group and antibiotic group (P < 0.05). As can be seen here, each test group improves the index of broiler chicken immune organ all to some extent, and the growth of broiler immune organ is served significant active influence.
As shown in Table 5,3,6 week old time, no matter be T lymphocyte percentage or ND_HI antibody titre, experiment 3-8 group is all remarkably higher than blank group and antibiotic group (P < 0.05). As can be seen here, each test group all can promote broiler cellular immunization and humoral immunization in various degree.
By result above it can be seen that the broiler chicken feed additive product of the present invention is for broiler, its adding weight can be increased; Improve Lipid in Chicken metabolism, promote meat; Improve broiler immunocompetence, the various diseases in prevention growth course, improve survival rate.
