Feeding and Reproduction in Gilts and Sows
With modern lean gilts there is considerable evidence to suggest that such gilts should be fed ad libitum from the time of selection until they are bred at their second or third estrus. Pregnant gilts should not be fed high levels (in excess of 2.5 kg/day) in early gestation. For sows that have lost considerable weight (in excess of 15 kg) during lactation, high levels of feeding in early gesta...
متن کاملSeasonality of reproduction in gilts and sows.
In the wild, the pig adapts her reproductive functions according to the seasonal changes in the environment, such as the ambient temperature and availability of food. Like in other short day seasonal breeders, breeding season is favoured in the mid winter in order to provide the offspring with the best chances to survive four months later. Seasonal changes in environment are perceived mainly by...
متن کاملGenetic parameters for reproduction and production traits of Landrace sows in Thailand.
Data from Thai Landrace sows were used to estimate genetic parameters for reproduction and production traits in first and later parities. The reproduction traits investigated were total number of piglets born per litter (TB), number of stillborn piglets (SB), and number of piglets born alive but dead within 24 h (BAD). The reproduction data pertained to 12,603 litters born between 1993 and 2005...
متن کاملReproduction of group-housed sows
The sow is a social animal in her behavior throughout the reproductive cycle. An exception to her preference for being a part of a social group occurs one to two1-2 d days prior to farrowing, when she separates from her group and seeks for isolation in order to build up a nest. She then spends the first week or two with her piglets, mainly in the nest. After this short period of separation of 1...
متن کاملThe impact of season, parity and breed on selected reproductive performance parameters of sows
The aim of the study was to identify the detailed impact of the season, parity and breed on reproductive performance of sows. The experimental material consisted of 2100 sows, in 3 breed variants: 700 PL, 700 PLW, 700 crossbreeds PL×PLW. Sows were observed until parity 5. In the context of the breed, depending on the order of parity groups of 140 sows were isolated. Then, sows were divided in t...
