| dc.description.abstract | The pressure that the swine sector has been suffering searching for methods and techniques that are more efficient, capable of increasing the number of piglets per sow, led to the hiperprolific sows, which go against the conventional concepts of swine facilities concerning farrowing crates. Also, the animal welfare when it comes to farrowing crates starts to become a very discussed subject, as much for the piglets as for the sows. After several studies developed in various locations, which evidenced the benefits of farrowing crates with mixed litters, it was decided to study that kind of litter. Thereby it was tested if the productive values of hiperprolific sows would increase, and also if it would increase the welfare of the piglets. The study was conducted between 11th of April and 19th of July in Santo Cristo’s farm, which is exploited by Euroeste, SA. company, located in Cartaxo, Portugal. The aim of this study was to evaluate if mixed litters help to wean more piglets, if they gain more weight by having more food options, and if their welfare is improved, helping the animal to be better prepared for the future, after weaning. Initially, through analysis with SAS software, which included the fixed effects of type of method used (if mixed litter or control), the location in the farm where they were, the month of birth, the age at weaning and the cycle of the sow, we evaluated the number of piglets weaned per sow, the average weight per weaned piglet, the daily weight gain calculated with the total values of the weights, the daily weight gained calculated with the average values of the piglets, and the percentage of weaned animals in comparison to the initial number of litters. Secondly, through the SAS program, were analysed the individual weights registered at weaning of 857 piglets, with an average weight of 5,91±1,41kg, with the aim of evaluating the environmental factors such as the method, location in the farm, month of weaning, age at weaning, cycle of the sow and age of the piglets at the beginning of the study. In conclusion for the production parameters this method does not show significant improvements however, it also has no disadvantage in productive terms, which demonstrates that it is a viable alternative to the intensive systems of isolated farrowing systems implemented today in most of the intensive farms. Secondly, it can also be concluded that, in behavioural terms, this method showed some improvement in pre-weaning behaviour, by improving the interactions between litters, and the natural contact between the animals and the increase of consumption of pre-starter. | pt_PT |
