A gilt-developer diet will have the appropriate levels of protein, energy and amino acids while having a much higher level of calcium, phosphorus and other trace minerals and vitamins compared to grow/finish or show pig diets. Additionally, the frequencies of dystocia, total piglets born/litter, live-born piglets/litter, stillborn piglets/litter, and mummies/litter were recorded. Several studies show that when nulliparous sows (gilts) are too fat (> 22 mm) at farrowing, they will have a lower feed intake in lactation, will lose more body weight during lactation and will have a lower reproductive performance. The normal gestation length of a sow or gilt is typically 115 days (three months, three weeks and three days) measured from the first day of service, although a range of 113 - 117 days is quite normal.

Timed artificial insemination is a relatively simple reproductive technology in batch farrowing production and we found two improved timed artificial insemination protocols could improve the oestrus and farrowing rates of weaned primiparous sows in batch. It was a bit of a head scratcher and we saw it go away after we medicated the sows with CTC in the feed. However, compared to double insemination in gilts, single insemination was associated with a lower farrowing rate (P<.

The newborn piglet requires a temperature of 34 C at birth, which is reduced to 28-30 C at weaning, while the sow’s preference is a temperature of 20-22 C at farrowing and 15-16 C at 3-4 weeks after farrowing while milk production and feed intake peaks. The interval to estrus after weaning and duration of estrus in sows can be influenced by length of lactation, nutrition, body condition, genetics, housing, boar exposure, and other management practices ( see Table: Factors Affecting Ovarian Activity of Pigs Factors Affecting Ovarian Activity of Pigs ). Provide adequate ventilation at all times. It allows inseminating the gilt on its second or third recorded heat. the farrowing rate and litter size in gilts and sows are shown in Table 1. performance.

First-litter sows weighing more than 175 kg after farrowing are better protected against reduced fertility due to large weight losses in lactation. 8%, 80. The trigger for farrowing (parturition) to start comes from the piglets, not the sow. Breeding dates should be recorded because the sows need to be moved to a controlled environment for optimum success. However, some studies observed negative effects associated with induction, including decreased piglet viability, reduced birth weight and decreased colostrum yield. Fertility and culling data were collected in connection with monthly visits to the farms for 16.
