There is currently a shortage of purebred sows in the Chinese market. During the epidemic, the channels for importing breeding pigs from abroad were also affected. There are many shortcomings of domestic ternary sows reserved for breeding.
Make up for the shortcomings of Domestic ternary sow and Improving their performance are possible to reduce lots costs for enterprises.
The ternary sow has a 50% Duroc pig lineage. It faces poor motherhood, low birth rate, low milk, difficulty in estrus, high estrus rate, short service life, many reproductive disorders, and slow growth of offspring.
Problem(A)
The nutrition and initial estrus period in the reserve cultivation stage are uncertain. Due to its rapid growth rate, the estrus is not obvious, the success rate of breeding is lower, and the first child is easy to give birth.
Improvements:
First love (There is a special person and a breeder who cooperates to induce love 2 times a day after 140~150 days, and records the first love period).
File record: After the measurement, look at the ear number and record the above data, and put the ear tag on the gilt. Breeding by experienced breeders.
Problem(B)
External ternary hybridization has relatively low resistance to stress and disease, and poor bone development, prone to limb foot disease.
Improvements:
Strict control according to standards to improve feed nutrition.
Feed balanced feed to ensure the supply of trace elements such as minerals, vitamins, calcium, phosphorus, zinc, copper, selenium, manganese.
-Biotin: It can improve the hardness, compressibility and compressive strength of the hoof shell, improve the condition of the skin and coat and reduce the symptoms of hoof shell fragmentation and hoof pad damage;
-Natural dried corn is rich in linoleic acid and is not damaged;
-Both puffed soybeans and soybean oil contain a large amount of linoleic acid, which has a certain effect on the absorption of biotin.
Therefore, when formulating feed for breeding pigs that are prone to crack hoofs, it is recommended to use natural dry corn (rather than drying or storing grain corn),add soybean oil or a certain proportion of expanded soybeans to improve the utilization of biotin by the breeding pigs.
Problems(C)
Reproductive system development defects caused by nutritional differences.
The fattening pig feed contains more heavy metal elements which will cause the pig ovaries to shrink or stunt. It will also cause the reserve growth rate to be too fast, resulting in poor development of bones and reproductive organs, which not only affects the estrus breeding of reserve sows, but also shortens the service life of the breeding pigs.
Improvement:
Pregnancy feed and lactating sow feed will cause uneven maturity and sexual maturity in the early breeding process of gilts, which leads to developmental delay. The sows reserved for breeding can be 7% to 10% higher in crude protein, lysine, calcium, and phosphorus than commercial pigs.
Problems(D)
Problems such as feed ingredients lead to the accumulation of toxins in the herd (mycotoxins), and health is the basis for production performance.
Improvement:
In view of the current widespread toxin accumulation and sub-health problems in pig farms, Shandong Longchang Animal Protection launched the sow rejuvenation plan! The sow rejuvenation plan is based on the problem of sows on the farm, by detoxification, hepato protection, regulating reproductive stress, and digging out the reproductive potential of sows, to solve the problems of toxin accumulation, sub-health, many weak piglets, decreased sow lactation, delay edestrus, and insignificant estrus. Based on the Lachance bile acid + Eucommia leaf extract, the sow herd on the farm is back to its peak. The Longchang SowRejuvenation Plan will return a brand new sow to the farm in 3 weeks, really helping you make money!
