【摘要】：發(fā)酵酒糟是用特定的微生物接種酒糟資源,借助微生物在無氧或有氧條件下的生命活動(dòng)來分解有機(jī)物獲得的酵解產(chǎn)物。為研究其對家禽的影響,本課題從肉雞與蛋雞兩個(gè)方面進(jìn)行了如下研究。研究了發(fā)酵酒糟對肉雞的營養(yǎng)價(jià)值評定,試驗(yàn)選用64只體重相近、健康的25日齡AA肉仔雞,隨機(jī)分為4個(gè)處理,每個(gè)處理4個(gè)重復(fù),每個(gè)重復(fù)4只雞,采用套算法測定肉仔雞對發(fā)酵酒糟中粗蛋白利用率和表觀代謝能。一組飼喂基礎(chǔ)日糧為對照組,二組飼喂在基礎(chǔ)日糧的基礎(chǔ)上添加20%低纖維發(fā)酵酒糟的日糧,三組飼喂在基礎(chǔ)日糧的基礎(chǔ)上添加20%高纖維發(fā)酵酒糟的日糧,四組為禁食組以測定Qg源損失。預(yù)試期3 d,正式試驗(yàn)期4 d。結(jié)果表明:高、低纖維發(fā)酵酒糟的蛋白含量分別為16.82%和25.88%,均明顯優(yōu)于玉米,且低纖維發(fā)酵酒糟的表觀代謝能為11.9 MJ/kg,與玉米相近。肉仔雞對高、低纖維發(fā)酵酒糟的粗蛋白質(zhì)利用率分別為39.58%和46.91%�？梢�,發(fā)酵酒糟對肉仔雞有較高的營養(yǎng)價(jià)值,并且低纖維發(fā)酵酒糟的營養(yǎng)價(jià)值相對更高一點(diǎn),可以替代部分蛋白飼料原料。研究了日糧中添加發(fā)酵酒糟對肉雞的影響,選取健康狀況良好,體重相近的1日齡AA肉仔雞440只,隨機(jī)分為A、B、C、D、E 5個(gè)組,每組8個(gè)重復(fù),每個(gè)重復(fù)11只雞,A組為對照組飼喂基礎(chǔ)日糧,B組飼喂添加2.5%低纖維發(fā)酵酒糟的試驗(yàn)飼糧,C組飼喂添加5%低纖維發(fā)酵酒糟的試驗(yàn)飼糧,D組飼喂添加2.5%高纖維發(fā)酵酒糟的試驗(yàn)飼糧,E組飼喂添加5%高纖維發(fā)酵酒糟的試驗(yàn)飼糧,試驗(yàn)期共35天。結(jié)果表明:日糧添加發(fā)酵酒糟提高了肉雞出欄重、平均體增重、平均采食量、料重比。日糧添加發(fā)酵酒糟提高了肉雞血清尿酸和葡萄糖含量,降低血清總膽固醇含量;提高了肉雞空腸乳酸桿菌和雙歧桿菌含量,其中5%低纖維發(fā)酵酒糟添加組效果最為顯著。研究了日糧中添加發(fā)酵酒糟對蛋雞的影響,選用相同周齡、體型基本一致、產(chǎn)蛋率為78%的產(chǎn)蛋后期海蘭褐蛋雞600只,隨機(jī)分為5個(gè)處理,每個(gè)處理10個(gè)重復(fù),每個(gè)重復(fù)12只雞。處理1為對照組飼喂基礎(chǔ)日糧,處理2、處理3、處理4、處理5分別飼喂在基礎(chǔ)日糧基礎(chǔ)上添加2%、4%、6%、8%發(fā)酵酒糟的試驗(yàn)日糧,試驗(yàn)期共8周。結(jié)果發(fā)現(xiàn):日糧添加發(fā)酵酒糟一定程度上降低了海蘭褐蛋雞的料蛋比,提高了產(chǎn)蛋率,降低了平均蛋重,提高了總產(chǎn)蛋重,降低了不合格蛋率;一定程度改變海蘭褐蛋雞所產(chǎn)蛋的蛋黃顏色,降低了蛋白高度,改變蛋黃蛋白比重,提高了蛋殼厚度,改善蛋殼顏色,降低蛋黃膽固醇含量,提升了蛋清抗氧化能力;降低血清中尿酸含量;減少蛋雞空腸乳酸菌、沙門氏菌、致病大腸桿菌的數(shù)量,提升了空腸內(nèi)容物的乙酸含量。綜合來看,2%劑量應(yīng)為最適發(fā)酵酒糟添加量。研究了日糧及飲水中添加發(fā)酵酒糟對蛋雞的影響,選用相同周齡、體型基本一致、產(chǎn)蛋率為77%的產(chǎn)蛋后期海蘭褐蛋雞48只,隨機(jī)分為2個(gè)處理,每個(gè)處理2個(gè)重復(fù),每個(gè)重復(fù)12只雞。0%組為對照組飼喂基礎(chǔ)日糧,4%劑量組飼喂在基礎(chǔ)日糧基礎(chǔ)上添加4%發(fā)酵酒糟的試驗(yàn)日糧,兩組飲水處理均為100公斤水加A、B發(fā)酵酒糟液體各1升,試驗(yàn)期4個(gè)周。結(jié)果發(fā)現(xiàn):日糧及飲水中添加發(fā)酵酒糟可改善蛋品質(zhì),降低產(chǎn)蛋率但提高總產(chǎn)蛋重。本研究表明,發(fā)酵酒糟營養(yǎng)成分含量較高;肉雞對發(fā)酵酒糟的表觀代謝能和粗蛋白利用率較高。日糧中添加發(fā)酵酒糟提高了肉雞的生產(chǎn)性能與經(jīng)濟(jì)效益,提高了血液中營養(yǎng)代謝水平,改善腸道菌群結(jié)構(gòu)。日糧中添加發(fā)酵酒糟提高了蛋雞的產(chǎn)蛋率并降低了料蛋比,改善了雞蛋品質(zhì),降低不合格蛋率,并改善了腸道微生態(tài)環(huán)境,提高免疫力。日糧及飲水中同時(shí)添加發(fā)酵酒糟對蛋雞也有一定效果。
[Abstract]:Fermented distiller's distiller's distiller's grains are inoculated with specific microbes to inoculate distiller's grains resources and decompose organic products by microorganisms in anaerobic or aerobic conditions. In order to study their effects on poultry, the subject has been studied from two aspects of Broilers and laying hens. The evaluation of the nutritional value of fermented distiller's grains to broilers was studied. 64 AA broilers with similar weight and healthy 25 day age were randomly divided into 4 treatments, each of which was treated with 4 repetitions, each repeated 4 chickens. A set algorithm was used to determine the utilization rate of crude protein and apparent metabolic energy in the fermented distiller's distiller's distiller's distiller's grains by a set algorithm. A group of basal diets was fed as the control group, and the two groups were fed 20% low fiber on the basis of basal diet. On the diet of fermented distiller's grains, the three groups were fed with 20% high fiber fermented distillers' grains on the basis of basal diet, and the four groups were fasting groups to determine the loss of Qg source. The pre trial period was 3 D and the formal test period 4 d. showed that the protein content of the low fiber fermented distiller's grains was 16.82% and 25.88% respectively, which were obviously superior to those of the corn, and the low fiber fermented distiller's grains were all obvious. The apparent metabolic energy is 11.9 MJ/kg, similar to that of corn. The utilization rate of crude protein of broiler to high and low fiber fermented distiller's grains is 39.58% and 46.91%., respectively. The fermented distiller's grains have higher nutritional value to broilers, and the nutritional value of low fiber fermented distiller's distiller's grains is a little higher, which can be used as a substitute for some protein feed materials. The effect of fermented distiller's grains on broilers was added to the diet, and 440 AA broilers, 1 days old, were randomly divided into 5 groups, A, B, C, D, E. Each group had 8 repetitions, each repeated 11 chickens, the A group was fed as the basal diet, the B group fed the 2.5% low fiber fermented distiller's grains, and the C group fed 5% low fiber. The experimental diet of fermented distiller's grains, D group was fed with 2.5% high fiber fermented distiller's grains, and the experimental diet supplemented with 5% high fiber fermented distiller's grains was fed in group E for 35 days. The results showed that the diet added fermented distiller's grains increased the weight of the broilers, the average weight gain, the average feed intake and the ratio of feed to weight. The diet added the fermented distiller's grains to improve the meat. The content of serum uric acid and glucose decreased the content of total cholesterol in serum, increased the content of Lactobacillus and Bifidobacterium in broiler jejunum, and the effect of adding 5% low fiber fermented distiller's grains was the most significant. The effects of the fermented distiller's grains on the laying hens were studied. 600 Brown laying hens were randomly divided into 5 treatments, each treated with 10 repetitions, each repeated 12 chickens. Treatment 1 was fed to the control group for basal diet, treatment 2, treatment 3, treatment 4, and 5 to add 2%, 4%, 6%, and 8% fermented distillers' grains on the basis of basal diet, for a total of 10 weeks. The results were as follows: diet added fermented distiller's grains. To a certain extent, the ratio of egg to egg was reduced, the egg production rate, the average egg weight, the total egg weight, the egg yolk, the egg yolk color, the protein height, the egg yolk thickness, the color of the eggshell and the yolk were reduced to a certain extent. Cholesterol content increased the antioxidant capacity of egg white, reduced the content of uric acid in serum, reduced the number of lactic acid bacteria, Salmonella, and pathogenic Escherichia coli in laying hens, and increased the content of acetic acid in the jejunum. The 2% dose should be the optimum addition of fermented distiller's grains in the diet and drinking water. With the same week age and the same age and the same body shape, 48 egg laying hens were divided into 2 treatments at the late egg production rate of 77%. Each treatment was treated with 2 repetitions. 12 chicken.0% groups were fed to the control group for the basal diet. The 4% dose group fed the experimental diet with 4% fermented distiller's grains on the basis of the basal diet, and the two groups of drinking water treatment were 10. 0 kg of water and A, B fermented distiller's distiller's distiller's liquid each 1 litres, the test period 4 weeks. The results showed that the diet and drinking water added fermented distiller's grains could improve the egg quality, reduce the egg production rate but increase the total egg production weight. This study showed that the content of the fermented distiller's grains was higher, the apparent metabolic energy and the crude protein utilization rate of the fermented distiller's distiller's grains were higher. The fermentation distiller's grains improved the production performance and economic benefit of broiler, improved the level of nutrient metabolism in the blood and improved the structure of intestinal flora. Adding Fermented distiller's grains in the diet increased the egg production rate and reduced the ratio of egg to egg, improved the quality of eggs, reduced the rate of unqualified eggs, and improved the microecological environment of the intestines, and improved the immunity. Dietary and Adding fermented distillers grains to drinking water also has some effect on laying hens.
