Broiler chicks’ motivation for different wood beddings and amounts of soiling

In the wild, excreta soiled surroundings can attract predators and spread disease. Yet, farmers rear broiler chicks in large barns with stocking densities that prevent excreta segregation. To measure chicks’ motivation to access unsoiled bedding or soiled litter (collectively, substrates)...

Challenging a myth and misconception: Red-light vision in rats

Due to the lack of L-cones in the rodent retina, it is generally assumed that red light is invisible to rodents. Thus, red lights and red filter foils are widely used in rodent husbandry and experimentation allowing researchers to observe...

Cow in Motion: A review of the impact of housing systems on movement opportunity of dairy cows and implications on locomotor activity

As humans, we recognize the importance of exercise. We go to the gym, walk our dogs, and ride our horses. Even our hamsters get a wheel to run on. Considering this, it is surprising that, when it comes to the...

Current welfare state of pet guinea pigs in the UK

Little research has been carried out into how guinea pigs are cared for in the UK, and information regarding potential welfare issues is sparse. This study was designed to examine the five welfare needs, collecting data on the extent to...

Evaluation of the physical properties of bedding materials for dairy cattle using fuzzy clustering analysis

The bedding materials used in dairy cow housing systems are extremely important for animal welfare and performance. A wide range of materials can be used as bedding for dairy cattle, but their physical properties must be analysed to evaluate their...

Fasting is not required for measuring plasma lipid levels in rabbits

Plasma lipid and glucose levels are important parameters for evaluating the onset and development of metabolic and cardiovascular diseases. In clinical and experimental studies of humans or mice, fasting is often required before testing plasma lipid and glucose levels. The...

Early life experience and alterations of group composition shape the social grooming networks of former pet and entertainment chimpanzees (Pan troglodytes)

The long-term effects of early life adversities on social capacities have been documented in humans and wild-caught former laboratory chimpanzees (Pan troglodytes). However, former pet and entertainment chimpanzees have received little attention to date. This study aimed to investigate the...

Early weaning disrupts feeding patterns in female juvenile rats through 5HT-system modulations

Convergent evidence in literature shows that rapid disruption of maternal care and breastfeeding due to an early weaning protocol changes the development of several neurobehavioral patterns in rodents, including the circadian pattern of feeding. The serotoninergic system has been associated...

Effect of different milk-removal strategies at weaning on feed intake and behavior of goat kids

Weaning from milk is stressful. We aimed to investigate the effect of three weaning strategies on feed intake and behavior of dairy goat kids. Forty-five, 3-month-old Saanen cross goats were allocated to one of three treatments: abrupt removal of milk...

Effects of trio and pair breeding of mice on environmental parameters and nasal pathology and their implications for cage change frequency

According to the Guide, cage change frequencies must be considered when cage density requirements are exceeded. We monitored ammonia, carbon dioxide, cage wetness, health status, and breeding parameters of trio and pair breeding cages containing CD1 mice in ventilated and...
