Description

A kind of fatty powder and preparation method thereof for fowl
Technical field
The invention belongs to field of feed, be specifically related to a kind of fowl fatty powder and preparation method thereof.
Background technology
In spermatoblast fat, contain more than 50% unrighted acid, and taking PUFAs main, PUFAs be sperm metabolism andCompleting of some physiological function provides energy. Fish meal increases the content of ω-3PUFAs in turkey diet, finds that turkey sperm is thinIn born of the same parents, ω-3PUFAs significantly increases, ω-6: ω-3 ratio significantly reduces, and sperm motility significantly improves, and is improved hatchingThe trend of rate, reduction rate of embryonic death. The adipose-derived remarkable aliphatic acid composition that affects plasmalemmae of sperms of feed, and with seminal fluid productMatter height correlation, fish oil can improve kind of a fertility for cock seminal fluid, and on young cock improve effect more obviously,Lastingly, but only add fish oil, in sperm, PUFAs content is higher, is very easily subject to the attack of active oxygen, and oxidative damage occurs,Thereby reduction semen quality, affects rate of fertilization.
One piece of egg is approximately containing 10% fat, and in the hatching process of 21 days, in yolk, 80% fat is inhaled by embryonic developmentReceive and utilize. Except providing energy for embryonic development, fat can also provide embryonic development necessary aliphatic acid, as AA,The long-chain polyunsaturated fatty acid such as EPA and DHA provides needed raw material for embryonic development. Fat in yolk is mainly derived from feedAnd self is synthetic. By provide different greases can change the aliphatic acid composition in yolk to animal, and impact kind of fowl breedingPerformance and mother, filial generation immune performance. In aliphatic acid composition in yolk and hatching process, the relation of Embryo mortality, is rich in ω-3The hatchability of fertile eggs of PUFAs is relatively high.
In modern poultry diet, aliphatic acid composition is unbalanced, forms unbalanced aliphatic acid and piles up at subcutaneous and belly, easily fertileFat. And with oil is complicated, quality is unstable, hinder fatty acid metabolism, cause significant quantities of fat to be piled up at liver, form fatty liver.As livestock and poultry diet is mainly corn-soybean meal, the grease in feedstuff is mainly corn oil and soya-bean oil, and soya-bean oil contains approximately 6% AsiaFiber crops acid, the omega-fatty acids such as EPA, DHA are zero, the omega-fatty acid such as leukotrienes, EPA, DHA of corn oil is zero,And both are not all containing Short-Chain Fatty Acids; Daily ration is commonly used grease: soya-bean oil, phosphatide oil, lard and palmitic omega-fatty acid,Short-Chain Fatty Acids is also zero, causes daily ration to lack omega-fatty acid and Short-Chain Fatty Acids, and aliphatic acid composition is unbalanced,Be more prone to lithosomic body fat, single aliphatic acid easily produces dysbolism at liver, forms fatty liver.
, plant at present in the use procedure of fowl grease meanwhile, due to the improper use of grease, cause kind of a fowl obesity, easily fat occurThe variety of issues such as fat liver, laying rate and incubation rate are low.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, fowl fatty powder and preparation method thereof is provided. System of the present inventionStandby fowl is higher by fatty powder utilization rate, and technique is simple, the use amount of processing ease, saving grease, and cost is low, also simultaneouslyCan improve immunity and the reproductive performance of animal, can effectively prevent that fat from forming fatty liver in liver accumulation.
For achieving the above object, the present invention has adopted following technical proposals:

In Huizhou, certain chicken house completes in test, and test period is age in 38-52 week, in November, 2014-2015 years 3Month.
1.2 experimental animals and grouping
7500 plumage Chinese ephedra kind hen in 38 week age (behind the peak of laying eggs 10 weeks) is selected in this test, is divided at random two processed group,Be respectively control group and test group, 3750 of each processing.
1.3 test diets
Test diet is corn bean pulp type daily ration. Control group diet: basal diet; Test group is embodiment 3 diets: 2.5%Corn in fatty powder equivalent substitution basal diet for fowl, other component is the same;
1.4 feeding and management
Adopt stacked raising in cages, 3 chickens of every cage. Artificial limit is raised, and feeds according to feed intake 140g/ (only × sky), freely drink water,Nature and artificial lighting combination, gravity-flow ventilation. Carry out immunity inoculation according to chicken house routine immunization program.
1.5 testing index
1.5.1 egg laying performance
The feeding coal and the surplus material amount that weigh two processed group every day, weigh weekly egg size one time, within every two weeks, weighs a chicken heavy (every150 of individual processed group), calculate average daily ingestion amount, average daily gain, laying rate, qualified egg rate, feed consumption egg number ratio,Incubation rate and death rate.
1.5.2 egg aliphatic acid composition
Within the 3rd week, be 41 week age in test, from two processing, choose at random 6 pieces of eggs that egg size is basically identical, adopt gas phaseChromatography is carried out the mensuration of aliphatic acid composition.
1.5.3 Economic and Efficiency Analysis
According to feed price and baby chick price accounting economic benefit.
2 results and analysis
2.1 fowl with fatty powder on kind of an impact for chicken egg laying performance
Table 1 fowl with fatty powder on kind of an impact for chicken egg laying performance
As shown in Table 1,2.5% fowl does not have a significant effect to kind of a chicken average daily gain, death rate and kind egg size with fatty powder, andLaying rate, qualified egg rate, incubation rate obviously raise, and feed consumption egg number ratio is that 1 piece of required feed consumption rate of egg of every product obviously reduces.
2.2 fowl are the impact on aliphatic acid composition in egg with fatty powder
Table 2 fowl is the impact on aliphatic acid composition in egg with fatty powder
Add fowl fatty powder and obviously affect kind of an egg aliphatic acid composition. Compared with control group, fat for fowl prepared by embodiment 3Powder (C18:3, EPA and DHA) increases by 1.39%, and wherein DHA increase ω-3,1.23%, ω-6/ obviously reduce, than contrastOrganize low by 54.96%.
2.3 fowl are the impact on 38-52 kind chicken fanning economics in age in week with fatty powder
Table 3 fowl is the impact on 38-52 kind chicken fanning economics in age in week with fatty powder
As seen from the above table, the strong seedling feed cost of embodiment 3 units than control group low 0.014 yuan/only, deliver for sale per year 1000 ten thousand strongHealth baby chick, feed cost is saved 140,000 yuan. 38-52 every hen qualified kind of egg number of contribution of test group in age in week and healthy baby chickNumber increases respectively 3.77 pieces and 5.24, and healthy baby chick 1.5 yuan of valencys at cost/only, every baby chick of test group is sold return increasingAdd 7.86 yuan, 2.05 yuan of the feed costs that deduction increases, every hen net profit increases by 5.81 yuan. From analyzing above,In kind chicken diet, add fowl fatty powder and obviously improve kind of a chicken culturing economic value.
