Description
Technical Field
The invention belongs to the technical field of animal husbandry, and particularly relates to a Sichuan-Tibet black pig pregnant sow separate-meal feeding method and a compound feed.
Background
The Sichuan-Tibet black pig complete set is a high-quality flavor pig complete set which is successfully cultivated and has local special and independent intellectual property rights by a modern genetic breeding technology, gathering superior characteristic genes of excellent pig breed resources at home and abroad and performing systematic breeding and strict combining force research after 14 years of attack between the animal husbandry scientific research institute of Sichuan province and the Sichuan iron knight industry Limited company. The Sichuan-Tibet black pig takes local pig breeds such as Tibet pigs, Meishan pigs and the like as core breeding materials, overcomes the defects of small size, poor appearance, low fecundity and the like of the Tibet pigs, and integrates the excellent characters of the Tibet pigs and the imported pigs. Has the characteristics of high production efficiency, strong stress resistance, high carcass lean meat percentage, tender and juicy pork and aromatic flavor, and is an ideal pig breed for producing high-precision agricultural products. Currently, Sichuan iron knight industry Co Ltd is mainly raised in the Mianyang area.
The nutritional requirements of the Sichuan-Tibet black pigs are different from that of foreign pigs and local pig breeds, and the nutritional level of the feed can be accurately designed by accurately evaluating the nutritional requirements of the Sichuan-Tibet black pigs, so that the maximization of the economic benefit of the breeding of the Sichuan-Tibet black pigs is realized. In recent years, studies on energy substance conversion, metabolism and feeding standards of Sichuan-Tibet black pigs have been reported, but systematic analysis and studies are lacking. The sow is the key of the live pig industry, and the breeding performance of the sow directly determines the production level and the breeding profit. The nutrition required by the same pig species in different growth stages is different, so that a scientific and reasonable feeding plan needs to be made according to the nutrition requirements of the pig species in different growth stages. At present, the Sichuan-Tibet black pigs are generally fed by daily ration prepared from DLY (DLY) foreign pigs, and certain nutrient components are deficient or excessive, so that nutrient imbalance is caused, and the production performance of the Sichuan-Tibet black pigs is influenced. Meanwhile, as the pregnant sow group of the Sichuan-Tibet black pigs is not large at present, refined feeding can be adopted. The biorhythm is divided into an active phase, in which the animal takes up more protein and carbohydrates than fat, and a sleep phase, in which the nutritional requirements favor the uptake of fat, and in which the entry into the active phase favors the uptake of glycogen.
Therefore, according to the reproductive physiological characteristics of pregnant sows of Sichuan-Tibet black pigs, different diets are given to the pregnant sows of Sichuan-Tibet black pigs in the morning and in the afternoon, and a method of nutrition grading and batching in the morning and in the afternoon is adopted to achieve the purposes of reducing feed consumption, saving feed cost, improving the utilization rate of nutrient substances, ensuring the nutritional requirements of the pregnant sows and laying a nutritional foundation for the lactation period.

Test example 1
Pregnant sows of Sichuan black pigs were fed with the compound feeds prepared in examples 1, 2 and 3 and tested in comparison with the existing commercial feeds. The commercial feed is a pregnant sow feed T7 of Sichuan iron rider industry Co., Ltd, and specifically comprises the following components:
100 bred Sichuan-Tibet black pigs with similar weight and gestation are selected, and are divided into five treatment groups, each group has 25 pigs, and the test period is 120 days by adopting single-factor completely random test design. Five groups of Sichuan-Tibet black pigs were fed with the compound feed of examples 1, 2 and 3 and the commercial comparative feed for T7 sows, respectively, and the feeding conditions were the same. Examples 1, 2 and 3 feed 7:00 for breakfast and 16:00 for dinner diets, as compared to a commercial comparative T7 sow diet, which was also fed 7:00 in the morning and 16:00 in the afternoon.
After the test is finished, the reproductive performance (total litter size, number born alive litter size, weight of newborn litter and constipation rate) of all the groups of Sichuan-Tibet black pig sows is measured.
Statistical analysis was performed on the test data using statistical software SAS9.1.3, and the test results were as follows:
TABLE 1 influence of different compound feeds on the reproductive performance of pregnant sows of Chuangzang black pigs
Note: indicates significant difference compared to control group (P < 0.05).
As can be seen from the table 1, the compound feed of the embodiments 1, 2 and 3 of the invention obviously improves the total litter size, the number litter size of live birth, the litter weight of birth and the standard reaching rate of the body condition of the sow in the gestation period of the Sichuan-Tibet black pig, and reduces the constipation rate.
Test example 2
Pregnant sows of Sichuan black pigs were fed with the compound feed prepared from breakfast and supper diets of example 1 and tested in comparison with the currently available commercial feed. The commercial feed is a pregnant sow feed T7 of Sichuan iron rider industry Co., Ltd, and specifically comprises the following components:
100 bred Sichuan-Tibet black pigs with similar weight and gestation are selected, and are divided into four treatment groups, each group has 25 pigs, and the test period is 120 days, by adopting a single-factor completely random test design. The four groups of Sichuan-Tibet black pigs were fed with the compound feed for breakfast and the compound feed for supper diets of example 1, respectively, in the same feeding conditions as the commercial comparative feed for T7 sows. Example 1 breakfast diets were fed at 7:00 hours and evening diets at 16:00 hours, respectively, and breakfast diets, evening diets and commercial comparative T7 sow chow were also fed at 7:00 am and 16:00 pm.
After the test is finished, the reproductive performance (total litter size, number born alive litter size, weight of newborn litter and constipation rate) of all the groups of Sichuan-Tibet black pig sows is measured.
Statistical analysis was performed on the test data using statistical software SAS9.1.3, and the test results were as follows:
TABLE 2 influence of different compound feeds on the reproductive performance of pregnant sows of Chuangzang black pigs
Note: indicates significant difference compared to control group (P < 0.05).
As can be seen from the table 2, the compound feed of the embodiment 1 of the invention obviously improves the total litter size, the live litter size, the birth litter weight and the standard reaching rate of the sow in the pregnancy period of the Sichuan-Tibet black pig, and reduces the constipation rate; the effect of the compound feed fed by breakfast daily ration and supper daily ration alone is lower than that of the compound feed fed by the example 1, and the effect is not different from that of a control group.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. The invention extends to any novel feature or any novel combination of features disclosed in this specification and any novel method or process steps or any novel combination of features disclosed.
