Effect test
And selecting a flock of 20-25 kg of weight in a black goat breeding base, dividing the flock into 7 groups, feeding 10 black goats in each group, feeding the feed compositions or feeds of examples 1-6 and comparative examples in different groups, and respectively calculating the feed intake speed and feed intake and weight gain data of the flock after sufficient feeding for 7 days.
The method for calculating the food intake speed comprises the following steps: the feed composition (feed) for each feeding was 50g, and 200g in total was fed in 4 times, and the time required for each black goat to finish 50g of the feed composition was recorded, and the average feeding rate of 10 black goats in the group was calculated.
The method for calculating the feed intake comprises the following steps: the feed composition was fed in a sufficient amount for 30 minutes per single daily meal, the feed intake in these 30 minutes was taken as feed intake data, and the average feed intake data of 10 black goats in the group was calculated.
The method for calculating the weight gain of the sheep flock comprises the following steps: the flocks are fed three times a day (morning, noon and evening), each time with a sufficient amount of feed composition (feed), and the average weight gain of different flocks is counted after 7 days of continuous feeding.
TABLE 1 average feed intake and average feed intake for different groups
As shown in Table 1, the feed composition provided by the invention in the embodiment 1-6 can effectively improve the feed intake speed and feed intake of the black goat, wherein the feed intake speed in the embodiment 3 is the fastest, and is as high as 8.1g/min, and the feed intake is also the largest, and can be as high as 276.3 g/meal.
TABLE 2 average weight gain after 7 days of feeding for different groups
As shown in Table 2, compared with the method for feeding the wangcao feed alone in the comparative example, the method for feeding the black goats by using the feed composition of the embodiments 1 to 6 can effectively improve the weight of the black goats in a short period, realize rapid weight gain, and can increase the weight by 5.61 jin at most after 7 days.
In conclusion, by adopting the feed composition for improving the feed intake of the black goats and the preparation method thereof, the feed intake and the feed intake speed of the black goats can be effectively improved, the weight of the mutton sheep of the black goats can be effectively improved in a short period, and the cultivation period is shortened.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
