Embodiment 1
[0038]This embodiment is a proportioning example of the full-price compound feed provided by the present invention. The full-price compound feed for sows who give birth in the same period during the day is adjusted to be made of the following raw materials in parts by weight, see Table 1:
[0039] Table 1 Feed formula for sows
[0040]
[0041]
[0042] 20 mg of copper sulfate, 0.24 mg of potassium iodate, 400 mg of ferrous sulfate, 60 mg of manganese sulfate, 0.50 mg of sodium selenite, 200 mg of zinc sulfate, 1.20 g of choline, 3500 IU of vitamin A, and 1.20 g of choline should be added to each kg of the full price material 150 IU, vitamin E 40 IU, vitamin K 0.6mg, vitamin B2 3.55mg, vitamin B1 1.0mg, vitamin B6 0.8mg, vitamin B12 10μg, biotin 0.3mg, available niacin 12mg, pantothenic acid 10mg, folic acid 1.2mg. By adding the above premix, the normal physiological needs of sows can be met, and the occurrence of trace element or amino acid deficiency can be avoided.

Embodiment 2
[0052] The application of a kind of full-price compound feed in sow feeding, its steps are:
[0053] This example is an example of relevant experimental data using the full-price compound feed prepared in Example 1, which is an example of the use effect.
[0054] Selected animals: 218 Landrace × Large White dual hybrid sows were selected for the test, with a gestation period of 110 days;
Embodiment approach
[0055] Implementation method: Divide the sows into Group A and Group B on average, feed the common sow full-price feed and the present invention's full-price feed respectively at 08:00-11:00 every day, and the feeding amount is 2kg; at noon and at night Feed normal sows full price feed of the same formula and weight. Feed until the end of sow farrowing test;
[0056] Effect record: Record the time when sows start to give birth and the live piglet rate. The implementation results are shown in Table 2:
[0057] Table 2. Effects of different full-price compound feeds for sows on farrowing time and live piglet rate of sows
[0058] group
[0059] Effect statistics: the present invention, under the same situation of feed intake, the delivery rate during the day of the test group (feeding the feed of the present invention in the morning, and feeding the common feed at night) has increased by an average of 65% compared with the matched group (feeding the common feed all d...
