Pigs have difficulty in performing heat exchange and; therefore, it is important to consider the environmental factors that impact their productive performance. This study evaluated the effect of thermal comfort and photoperiod on the productive performance of sows during pregnancy and of nursery...

A comparative study of the lipid and fatty acid composition of Atlantic salmon underyearlings reared under natural and continuous light in commercial aquaculture in the summer-autumn period in North Ossetia-Alania was carried out. The change in the main indicators of lipid metabolism in salmon...

The aim was to compare some stress responses to electroejaculation (EE), and the quality of fresh semen, when ram semen is collected at dawn (06:00 h), noon (12:00 h), or evening (18:00 h). Twelve Corriedale rams were used, and semen was collected from four rams at each study time on three...

Atlantic salmon undergo smoltification, a process that prepares the fish to enter and thrive in seawater (SW). Several physiological changes occur during smolting, especially in osmoregulatory tissues, the gill, the kidney, and the intestine. Here we characterized the effects on intestinal...

Historically, the control of straying, fertility and sexual behaviour or the modification of the estrous cycle has been based on surgical castration. However, the increase in the number of pets, of breeding subjects and the progression of scientific knowledge has meant that alternative solutions to ...

Female rabbits from the age of 9 weeks till age of maturity were reared in two separate groups under long (16L: 8D) and short (control) (12L: 12D) photoperiods. The primary follicles were characterized by the presence of single layer of cuboidal granulosa cells surrounding the oocyte. Does reared...

This paper describes the general husbandry and care procedures for rabbits, ferrets, parrots and bearded dragons in terms of diet/feeding, housing, photoperiod, behaviour, environmental factors and health.

Domestic felids (Felis catus) have been traditionally categorized as seasonal polyestrous with induced ovulation. Thus, the ability to augment or distribute the number of litters born throughout the year would offer a desirable advantage. Artificial-light regimens have been used to overcome...
