This study evaluated whether the specific heavy pig rearing context allowed the fattening of undocked pigs without an outbreak of tail biting. At the same time, gender and straw availability (small amounts) were considered to understand their possible interactions with tail presence in the display of tail biting. A 2 × 2 × 2 factorial design was adopted to(More)
Adopting a 2 × 2 × 2 factorial design, this study evaluated whether continuous straw provision by racks, tail docking and gender (barrows vs. females) have an effect on the prevalence of lung lesions and oesophago-gastric ulcer (OGU) visually scored at slaughter in 635 Italian heavy pigs (169 ± 4 kg). The lung lesions were very low (72% of pigs with score(More)
Pain alleviation associated with castration of piglets is an important welfare issue. The present study compares the effect of different approaches and products suitable for farmer use, with the aim to alleviate pain due to castration in piglets. A randomized within-litter design, with 28 replicate litters, compared 7 treatments: handling () restraint of(More)
Tail biting lesions have a negative effect on both the welfare of pigs and on the revenue of the pig farm. Due to the multifactorial nature of this abnormal behaviour and its sporadic onset, an epidemiological approach was adopted to identify the management and housing factors influencing the occurrence of tail biting and the frequency of bitten pigs in the(More)
Given that surgical castration is a painful practice performed on millions of pigs every year, a need to identify novel reliable pain assessment tools exists in order to test anaesthetic and analgesic protocols that may reduce related pain. Two treatments were considered: handling (H) and surgical castration (C). Physiological (cortisol, lactate, glycaemia,(More)
Human leukocyte antigen (HLA)-B and HLA-DRB1 typing in two female individuals revealed reaction patterns that did not correspond to any known HLA-B specificity and appeared to identify a very rare HLA-DRB1 allele, respectively. Sequence-based analysis of these samples revealed two new HLA alleles, one similar to B*4023 and the other to DRB1*1308. The new(More)
The objective of the study was to determine whether a less-invasive surgical technique used in cryptorchid horses, dogs and cats can be used successfully to remove retained testicles in pigs on farm. In total, 284 monolateral cryptorchid pigs underwent surgery on-farm condition, during which an incision was made over the inguinal ring and the undescended(More)
Oesophago-gastric ulcers (OGU) are a production and welfare problem in pigs. Stomach condition was scored for 22 551 pigs in 228 batches over a 7-month period at an abattoir in Italy processing heavy pigs for ham production. Mild or severe ulceration was observed in 20.7% of pigs, of which 13% had scar tissue. Variation between batches was high (0% to 36%(More)
