First, materials and methods
1. Source and feeding method of propolis powder: The propolis powder powder was purchased by professional rabbits from the local apiculture professional households. The propolis powder was mixed into the feed at a dose of 3% of the formulated diet.
2. Test animals and places: In this experiment, Belgium commercial meat substitute rabbits raised by professional families of rabbit breeding families were selected.
3. Selection and grouping of rabbits for the test: From the rabbits raised in the specialized households, 20 healthy rabbits with the same age or weight were selected and randomly divided into two groups, 10 in each group (the proportion of males and females was the same in both groups. ) The group that added 3% propolis powder to the basic diet was the experimental group, and the non-added group was the control group. The two groups had the same basal diet. The daily formula and nutritional level were: 26% corn, 15% bran, 15% of soybean cake, 40% of hay powder, 2% of bone meal, 1% of shell powder, 1.5% of salt, 0.5% of auxin, 11.52MJ/kg of digestive energy, 14.5% of crude protein, 14.4% of crude fiber, 0.95% of calcium, Phosphorus 0.53%. After grouping, a 7-day pre-test period was performed. During this period, the weights of the two groups were numbered, weighed, castrated, immunized, dewormed and regulated. After treatment with biometric data, there was no significant difference in body weight between the two groups (P >0.05), then enter the 60-day trial period.
4. Feeding and management: In this experiment, two groups were housed in double-row three-layer rabbit cages, with 2 cages per cage. The two groups were fed by the same breeder in the same room. The dry powder was fed with water and then fed. The feed was fed three times a day. The food was eaten freely and water was provided. Management measures are consistent in both groups. During the trial period, the responsible person was responsible for fixing the test data records and observation of the feeding situation. After the tests were all completed, statistical analysis was performed on the performance assessment indicators of the two groups of meat rabbits.
Second, results and analysis
1. Weight gain and material consumption: Average daily weight gain: As can be seen from the experimental conditions, a test group in which propolis powder was added to the diet of rabbits, the average daily weight gain of each rabbit within the trial period was (27.32.2) ) grams, the control group (25.12.6) grams, the test group than the control group increased by 8.8% daily gain, the comparison test, the difference between the two groups was significant (P <0.05).
Feed to weight ratio: In the experimental group where the rabbits were fed with propolis powder, the feed-to-weight ratio was 4.38:1 during the whole test period and 4.55:1 in the control group. The feed utilization rate of the experimental group was 3.7% higher than that of the control group. There was a significant difference between the two groups ( P<0.05).
2. Observation of feeding situation: During the trial period, a test group fed with propolis powder was added to the diet. Meat rabbits always showed a preference for food and feed intake, and the excrement of the excrement was normal, and no abnormalities were observed.
3. Analysis of Economic Benefits: A test group fed with propolis powder was added to the diet of rabbits. During the trial period, each rabbit had a gross profit of 8.56 yuan, compared with 8.21 yuan for the control group. The experimental group increased economic efficiency compared with the control group. 4.3%.
The experiment confirmed that adding a certain dose of propolis powder in the diet of rabbits had a certain effect on increasing daily weight gain, feed utilization, and economic benefits of the rabbits, which proved that it is feasible to use the propolis as a feed additive for rabbits. .
