Are female mice dehydrated during peak lactation? Effect of water and gel supplement on hydration parameters and water consumption in two strains of mice

Mice (Mus musculus) have a high basal rate of metabolism which increases during pregnancy and lactation. During peak lactation, water intake amounts to up to 65 % of the bodyweight per day. Providing water in a bottle may pose a...

Mice prefer draught-free housing

An increasing number of rodents are housed in individually ventilated cage (IVC) systems, as these seem to be very effective for the protection of animals against infections, as well as protecting the staff against allergens. For the IVC systems to...

Housing breeding mice in three different IVC systems: Maternal performance and pup development

A proper cage environment is essential for the welfare of laboratory mice, especially for females during the energy demanding lactation period and for pups during early development and growth. The most common housing system for laboratory mice is individually ventilated...

Optimal colloidal water gel type and novel placement for frequent travelers

During transportation, animals must have a water source available to prevent dehydration. Some shipping facilities use potatoes whereas, others use colloidal water gels that provide a uniform water source. The problem occurs when colloidal water gel containers are placed on...

Replacing soiled bedding sentinel rodents with environmental health monitoring: Evidence and tips

Traditional rodent health monitoring programs involve transferring soiled bedding from colony cages to sentinel cages. While it can vary, the sentinel animals are ultimately euthanized after 3-6 mo of soiled bedding exposure. Using traditional soiled bedding sentinel rodents has several...

Low luminosity reduces agonistic behaviour of Nile tilapia

In confrontations, many behaviors are based on visual information. To establish the importance of visual signals in the aggression of cichlid fish, we observed the behavior of groups in three juveniles of Nile tilapia (six groups in each condition), for...

Analysis of housing risk factors for the welfare of lean and heavy pigs in a sample of European fattening farms

Pig welfare is affected by housing conditions, the minimum requirements of which are set up by EU legislation. Animal and non-animal-based measures are useful indicators to investigate housing risk factors for pig welfare. An observational study on 51 pig farms...

Do rubber floor mats prevent lameness in gestating sows housed in large groups? A field experiment on three commercial farms in France

Lameness and foot disorders are major health and welfare issues in intensive swine production systems. They are exacerbated when sows are housed in large groups on slatted concrete floors during gestation. Our study aimed to assess the effect of rubber...
