Short intervals for fertilization are important for large numbers of lactating piglets

A short breastfeeding interval from conception to conception is important in achieving large numbers of lactating piglets. This is clear from the analysis of more than 1 million seeds of key individuals by the American Pig Management Systems (SMS).

Last year, SMS collected all data from a total of 572 seed farms in the United States. The figures only consider companies operating year-round. Companies that started or implemented a depot-repo are not included.

The farm size varies from less than five hundred to more than 5,500 seeds. The share of farms with 500-1,499 covered seeds is the largest with 232 farms. This is followed by 104 farms with 1,500-2,499 seeds. The group, which has more than 5,500 covered seeds, includes 22 companies.

Clear relationship is not the size of the company

The number of lactating piglets for closed sowing on farms varies from 23 to 34 piglets. This key person has no clear relationship with the size of the company. The only relationship is that farms with more than 5,500 seeds often attract 31 piglets or more. It’s ten out of 22 farms, but there’s one farm here that produces only 24 piglets a year.

It is necessary for many piglets to be born to achieve a large number of lactating piglets. Of the 572 farms, only 28 had 31 total piglets. In contrast, there are 45 farms with more than 40 piglets in total.

Great throw

The variation of piglets per litter is less than fourteen and more than seventeen. With large litters, according to SMS, there is often more variation in birth weight, with more vulnerable piglets and sometimes stillborn piglets or mummies. This variation requires good management after birth to achieve a large number of lactating piglets.

It is difficult to differentiate into one litter, but when a total of thirteen piglets are born, a seed farmer will not produce it if he wants to raise more piglets. It is difficult to milk more than 27 piglets per seed per year, as less than 15 total piglets are born per litter or 35 total piglets per litter.

Interval breastfeeding

Breastfeeding interval is one of the factors that play a role in the total number of newborn piglets. That gap has been narrowing in recent years, with more farms incorporating seeds within an average of 6.5 days. RIM 60 percent of companies are between 4.5 and 6.49 days old. However, the variation still ranges from 2.5–3.49 days to an average of more than 9.5 days.

Farms with higher average spacing do not exceed 23 lactating piglets per sow per year. To cross thirty lactating piglets per sow per year, the average breastfeeding interval from first fertilization should be less than six days.

To close the gap from the first fertilization, according to SMS, it is necessary to look at several things. What does the company do to increase seed fodder during the nursing period? What is the average intake per seed per day during lactation? What is the weight of the seeds that reproduce in the first fertilization?
