Experimental example 1
1. Materials and methods
The test was divided into 3 treatment groups, D1 (basal control group ration), D2 (basal formula +2 parts clostridium ethanolate protein), D3 (basal formula +4 parts clostridium ethanolate protein).
The breeding test was conducted in a test base at the south of the academy of agricultural sciences of China, and 324 representative broiler chicks (half of the male and the female) with Aijia meat were selected from poultry, purchased from Beijing Huadu broiler company. The broiler chicken nutritional requirement standard is prepared according to American NRC (1994), and adopts corn-soybean meal type basic ration. The positive control group D1 was fed a basal diet and the test groups (D2 and D3) were fed a diet supplemented with 2 and 4 parts of clostridia protein powder to the basal diet. Adopts double-layer cage culture, and can feed and drink water freely. Temperature in the chicken house: 33-34 ℃ after 1-3 days of age, reducing the temperature by 3 ℃ every week to 23-25 ℃ and maintaining the temperature within the temperature range, and timely adjusting the temperature according to the state of the chickens. The whole period (1-42 days old) is 24 h. Cleaning dung once every 5 days in the early stage of feeding, cleaning dung once every 3-4 days in the later stage, and carrying out spray disinfection once for cleaning dung for chicken each time. At the age of 7 days, carrying out nasal drip and eye drop immunization on the newcastle disease and infectious bronchitis combined live vaccine; at the age of 14 days, the vaccine for infectious bursal disease is used for drinking water immunization. Animals were observed daily for health including mental status, appetite and fecal status and the number of deaths recorded.
2. Main measuring index and statistical method
The growth performance indexes including body weight, daily feed intake, feed-meat ratio and death rate are mainly measured. The test data are statistically analyzed by one way ANOVA in SAS8.0, the mean value comparison among the treatments is subjected to significance test by Duncan's multiple comparison, the result is expressed by the mean value +/-standard deviation, and P < 0.05 is used as a significance judgment standard.
3. Results and analysis
3.1 Effect of Clostridium ethanolicum proteins on broiler feed intake
As can be seen from Table 1, the differences in daily food intake of the treatment groups at 1-22 days old, 22-24 days old and 1-42 days old were not significant (P > 0.05), indicating that the addition of Clostridium ethanolate protein in the daily ration did not adversely affect the food intake.
3.2 Effect of Clostridium ethanolicum proteins on broiler weight and daily gain
As can be seen from Table 1, the initial weight difference of the broilers between treatments is not significant (P > 0.05), the daily weight difference of treatment groups at 22-42 days of age is not significant (P > 0.05), the daily weight gains of the broilers at 1-21 days of age are significantly higher than D1(P < 0.05), wherein the difference between D2 and D3 is not significant (P > 0.05); the daily gain of the 1-42 days of age is significantly higher in the D2 and D3 groups than in the D1 group, and the difference between the D2 and D3 is not significant. The result shows that the weight gain effect of the group which adds 2 parts of clostridium autoethanolicum protein powder in the daily ration is optimal.
3.3 Effect of Clostridium ethanolicum proteins on feed conversion ratio of broiler chickens
As can be seen from Table 1, the F/G difference between the treatment groups at 1-21 days of age, 22-42 days of age and 1-42 days of age was significant (P < 0.05), with the broiler chickens at 1-21 days of age F/G, the D2 and D3 groups being significantly lower than the D1 group (P < 0.05), with no significant difference between the D2 and D3 groups (P > 0.05); broiler chickens F/G, D2 and D3 at 22-42 days of age and 1-42 days of age were significantly lower than D1(P < 0.05), with no significant difference between D2 and D3 (P > 0.05). The results show that the addition of 2 parts of clostridium ethanolate protein in the daily ration can effectively reduce the addition of soybean meal in the daily ration, and has no obvious adverse effect on the feed conversion ratio.
TABLE 1 Effect of different levels of Clostridium ethanolicum protein in diets on broiler growth Performance
In the research of the invention, the clostridium ethanolate protein in the daily ration replaces the soybean meal in the daily ration of the broiler chicken, so that the daily feed intake of the broiler chicken is not obviously influenced; compared with a control group, the daily gain of the broiler chickens of the clostridium ethanolate protein groups of 2 parts and 4 parts is obviously increased, and the feed-meat ratio is obviously reduced. Therefore, the clostridium ethanolate protein can be used for replacing conventional raw materials such as soybean meal and the like in the poultry feed, and 2 parts of clostridium ethanolate protein is most suitable for being added into the broiler feed in consideration of comprehensive cost factors.
