Approximately 5% of pigs slaughtered in the UK have been tail-bitten, leading to welfare and production issues. Tail biting is sporadic and not all pigs tail bite. The aim of this study was to identify factors that are common in pigs that perform tai

Clinical tail-biters were identified over a 12-month period at a commercial nucleus pig-breeding farm that had a history of tail-biting problems. The breed, gender, and relative size of the tail-biters were recorded. Using pedigree data for all the p

This study assessed the effect of predisposition to perform harmful social behaviour, maternal rearing environment, and lactation environment on the responses of pigs to weaning at 3 or 5 weeks of age. Predisposed and non-predisposed gilts were selec

Tail-biting and other harmful social behaviours are a common problem on pig farms. The aims of the current experiment were (1) to investigate the genetic component of harmful social behaviours such as tail-biting by assessing breed differences, and (

The selection for reduction in carcass fat content has resulted in the development of genetically lean sows that can experience reproductive problems. This experiment investigated the production consequences of applying a nutritional regime designed

The performance of tail biting and other harmful social behaviours is a common problem on pig farms. Many risk factors relating to tail biting have been identified, but the problem remains intractable. One contributory factor may be the genetic makeu

Tail-biting is an adverse behaviour which can lead to injury in the recipient pig, reducing welfare and causing abscesses in the carcass. A survey in abattoirs in the UK found that 5 percent of pigs at slaughter have their tails bitten (Guise & Penny

Harmful social behaviour is behaviour that is directed at pen mates which, if persistent, causes injury. It includes tail, ear and flank biting. The aim of this work was to determine if pigs that are predisposed to harmful social behaviour can be ide

Selection for the reduction of carcase fat and the promotion of lean tissue growth has resulted in the production of faster growing, genetically lean breeding females. These animals often have very limited body fat reserves to utilise at times of hig

Practical use is made of an increase in the ovulation rate of gilts over the first few oestrous cycles. In large herds it may well be easier to increase the interval between entry into the herd and first service in order to improve the size of the fi
