Neoplastic and Non-Neoplastic Proliferative Mammary Gland Lesions in Female and Male Guinea Pigs: Histological and Immunohistochemical Characterization

Animals
Mammary tumors occur in female and male guinea pigs. However, published data on their histology and sex predispositions are limited. Histologically, we examined proliferative mammary lesions of 69 female and 48 male pet guinea pigs.

Talking tails : quantifying the development of tail biting in pigs [PDF]

, 2010
Tail biting is an adverse behaviour characterised by manipulation of a pig’s tail by another pig resulting in tail damage and a possible tail biting outbreak. Tail biting is a common problem in the pig husbandry causing economic losses and reduced animal
