Description

Pregnant sow feed

Technical Field

The invention relates to a feed, and particularly relates to a feed for pregnant sows.

Background

The pregnant sows are sows in the physiological stage of pregnancy, and the feeding requirements of the pregnant sows firstly ensure normal development of fetuses, prevent dead fetuses and abortion, obtain a large number of strong piglets, secondly ensure good fatness of the pregnant sows, store nutrition for the lactation period, and aim at integrally improving the live pig yield and the economic benefit of a farm. However, in the breeding practice, the pregnant sows often have constipation, which has adverse effects on the normal development of fetuses and the improvement of the fat condition of the sows, and in addition, the pregnant sows often have empty chewing and brood behavior, which shows that the emotion of the sows in the gestation period is poor, and further the feeding quality of the sows and the fetuses is influenced. For the situations of constipation or empty chewing and fence biting of pregnant sows, people hope to prevent or improve the constipation or empty chewing and fence biting by improving the feed level, which is obviously superior to the treatment by selecting medicines, but no pregnant sow feed with strong pertinence and high cost performance exists at present.

Disclosure of Invention

The invention aims to provide the pregnant sow feed which can effectively reduce the occurrence of constipation of pregnant sows and relieve the situations of empty chewing and fence biting of the pregnant sows, has high cost performance and is convenient to popularize.

In order to achieve the purpose, the invention adopts the following technical scheme:

the pregnant sow feed is composed of the following raw materials in parts by weight:

40-50 kg of corn, 15-20 kg of Zhang miscellaneous cereals, 12-16 kg of bran, 0.4-0.6 kg of soybean oil and 16-20 kg of bean pulp.

Preferably, the weight ratio of the raw materials is as follows:

44 kg of corn, 18 kg of Zhang miscellaneous cereals, 14 kg of bran, 0.5 kg of soybean oil and 19 kg of soybean meal.

Preferably, 3-5 kg of premix is also added into the feed.

The invention also aims to provide application of the pregnant sow feed in preventing constipation of sows.

Still another object of the present invention is the use of the above-mentioned pregnant sow feed for alleviating empty chewing and hurting behavior of pregnant sows.

The Zhang miscellaneous cereals are high-yield millet hybrid varieties bred by Zhang family city agricultural science research institute, have the obvious characteristics of high yield and drought resistance, the yield in dry land can reach 400-. The nutritional composition comparison of the Zhangmiscellaneous cereals and corn is shown in Table 1:

as can be seen from Table 1, the crude protein and fat of Zhanghetu are less than 1 percent higher than those of corn; the fat and ash content is higher, and is higher than that of corn by 2-3 percentage points; the total phosphorus levels were comparable and these data indicate that part of the corn could be replaced with the starter grain as a feed ingredient and that the coarse fiber was significantly higher (3.5 times) than corn and that the increased coarse fiber was beneficial in promoting gastrointestinal motility and satiety, so that this compositional change could affect feed performance as a whole.

The pregnant sow constipation relieving and farrowing piglet feed has the advantages that by introducing the miscellaneous grain and adjusting the weight ratio of the components, constipation of pregnant sows can be improved clearly, empty chewing and brooding of the pregnant sows are effectively reduced, piglet quality during delivery is improved, the miscellaneous grain is low in price, and the cost can be reduced by replacing corns with the miscellaneous grain.

Detailed Description

The present invention will be described in detail below with reference to specific examples.

Example 1 pregnant sow feed formula 1

40 kg of corn, 15 kg of Zhang miscellaneous cereals, 12 kg of bran, 0.4 kg of soybean oil and 16 kg of soybean meal.

Example 2 pregnant sow feed formula 2

50kg of corn, 20 kg of Zhang miscellaneous cereals, 16 kg of bran, 0.6 kg of soybean oil and 20 kg of soybean meal.

Example 3 pregnant sow feed formula 3

Example 4 pregnant sow feed formula 4

In the above formulation, 3 kg of premix, which is generally commercially available, was added, and the ingredients were as follows:

10-18 ten thousand IU of vitamin A and vitamin D₃3-5 ten thousand IU, vitamin E500-560 IU, vitamin K₃50-90 mg of vitamin B₁18-22 mg of vitamin B₂80-100 mg, 500-550 mg nicotinic acid, 290-310 mg pantothenic acid, vitamin B₆15-25 mg of vitamin B₁₂100-150 ug, 10-25 mg folic acid, 5-12 mg biotin, 2100-2500 mg iron, 1000-5000 mg copper, 780-820 mg manganese, 5-7 g choline chloride, 2800-3200 mg zinc, 15-20 mg cobalt, 5-8 mg iodine and 3-9 mg selenium.

Example 5 feeding Effect

1. For improving constipation

200 pregnant sows with basically the same condition were divided into four groups of 50 pigs each, and the control group feed was: 50kg of corn, 16 kg of bran, 0.6 kg of soybean oil, 20 kg of soybean meal and 4 kg of premix. Test group 1 was according to formulation 3, test group 2 was according to formulation 4, test group 3 was according to

formulation

2 and 4 kg of premix was added.

The relationship between constipation and feeding days is shown in figure 1, the fecal condition is shown in figures 2 to 5, and it can be seen from the figures that the constipation condition of pregnant sows is improved in detail when the test is carried out to the 4d and 3 test groups; almost no constipation appeared in the sows of 3 test groups till 11d, and the constipation rate of the control group is maintained to be more than 15%. Meanwhile, along with the increase of the content of the miscellaneous grains in the daily ration, the color of the excrement of the sow is also changed. Therefore, the constipation condition of pregnant sows can be obviously improved by adding the Zhang miscellaneous cereals into the daily ration.

2. Influence on air chewing and biting behavior

The 260 sows were divided into two groups, a control group of 195, and the feed was: 50kg of corn, 16 kg of bran, 0.6 kg of soybean oil, 20 kg of soybean meal and 4 kg of premix. The feed formula 4 is adopted for 65 test groups, the behavior conditions of the sows in the test group and the sows in the control group are observed and recorded after the sows are fed for 2 hours and 3 hours respectively, and the results of the behavioral observation are shown in table 2.

TABLE 2 Effect on pregnant sow behaviour

As can be seen from Table 2, the conditions of empty chewing and fence biting of the pregnant sows in the test groups are improved, and the pregnant sows are respectively reduced by 4.78 percent and 1.79 percent after being fed for 2 hours and 3 hours.

The research shows that the behaviors of empty chewing, hurdling and the like are generally caused by sow movement and nutrition deficiency caused by feeding limitation and hurdle feeding. The Zhangmiscellaneous cereals in the feed formula of the test group can improve the satiety of the sows and make up for the influence caused by limited feeding to a certain extent, thereby improving the behavior of empty chewing and fence biting of the pregnant sows.

The above embodiments are merely illustrative of the inventive concept and implementation, and are not limiting, and technical solutions that are not substantially changed under the inventive concept are still within the protection scope.
