International survey on the use and welfare of zebrafish Danio rerio in research

A survey was conducted regarding zebrafish Danio rerio use for scientific research with a focus on: anaesthesia and euthanasia; housing and husbandry; breeding and production; refinement opportunities. A total of 98 survey responses were received from laboratories in 22 countries...

Retrospective review of surgical outcomes and pair-housing success in vasectomized rhesus macaques (Macaca mulatta)

Providing social housing for adult male macaques can be challenging. One successful strategy for long-term social housing of adult male macaques is to pair them with adult females; however, unwanted breeding must be prevented by sterilization of the male or...

Why do female desert lizards construct burrows to lay eggs?

Many oviparous animals construct well-designed nests to provide relatively favourable conditions for their eggs and hatchlings, but the direct evidence that nest structure can determine their reproductive success is insufficient. In the present study, we explored the structure of nests...

Ultrasound to UltraSee: The use of ultrasound to determine pregnancy in mice

In March 2017 MRC Ares bought an ultrasound machine to assist in determining pregnancy in timed mating mice. Prior to this, visual checks or palpation would be used to confirm pregnancy. There were limitations with these methods as mice generally...

Refining mouse re-derivation by using in vitro fertilisation (IVF) with fresh or frozen sperm as opposed to embryos

To attempt to reduce, refine and replace, we have employed a several new approaches to rederive mouse strains. By using in vitro fertilisation (IVF) with fresh or frozen sperm we can reduce the timeframe and number of animals required to...

Time’s up for tick-over colonies… Do we now need to maintain so many GA mouse lines?

The practice of continually breeding lines to maintain them as a live resource either in-between studies or indefinitely “just in case” is common practice in many animal facilities. This process of “ticking over” colonies has historically occurred due to the...
