ion of energy, protein, minerals and vitamins in the rat is provided by Keenan et al. (2000). Schug (2005) and Bielohuby et al. (2010) have conducted experimental st dies on the rat -specific evaluation of feed energy at the level of metabolizable energy (ME). Experimental work has shown that the equati

A laboratory animal's nutritional status influences its ability to reach its genetic potential for growth, reproduction, and longevity and to respond to pathogens and other environmental stresses. A nutritionally balanced diet is important both for the welfare of laboratory animals and to ensure that experimental results are not biased by…

This study aimed to provide a recommendable protocol for the preparation of brain cryosections of rats to reduce and avoid ice crystals. We have designed five different dewatering solutions ...

We have also used this protocol for 2 mg frozen liver tissue from adult rats and 10 mg frozen colon tissue from adult mice. Refer to key resources table and materials and equipment sections for a complete list of necessary solutions, materials and equipment.

PDF Best Management Practices for Feeder Rodent Production and Distribution

Introduction The feeder rodent industry is the business of growing and selling rats and mice - live and frozen - as a food source for reptiles and birds of prey. Domestic strains of the house mouse (Mus musculus) and Norway rat (Rattus norvegicus) comprise the vast majority of feeder rodents. A brief description of the life history and reproduction of these species is in Appendix A.

The authors describe an optimized protocol for rat sperm cryopreservation and in vitro fertilization using frozen -thawed sperm.

Guidelines on Experimental Food or Water Restriction or Manipulation in ...

If animals are receiving their daily ration of food/water as part of the experimental procedure, the approved protocol must clearly define when and how food and water will be provided on days when no experiments are conducted. Describe the method and frequency of monitoring in order to assure animal health.

experimental animals' nutritional requirements the type of research the experimental design the endpoints being measured Consider the formula - does it stay the same over time or can it change? Evaluate the diet manufacturer (quality control, technical support, diet availability, warehouse biosecurity, sales support and customer service)

Evaluation of Rodent Diet Stability when Stored in Conditions that ...

After receiving a suggestion for improvement for environmental conditions in 2 feed storage locations during an AAALAC accreditation visit, we hypothesized that the packaging of contemporary rodent feed could sustain wider environmental variations in temperature and humidity without adverse impact on integrity and palatability.

Testicular tissue freezing before gonadotoxic treatments allows the preservation of fertility for children suffering from cancer. Recently, the testis organ culture method was presented as a relevant method to restore the fertility of these patients. However, the yield of spermatozoa production is low in the mouse model and no gamete has been obtained in vitro in the rat model. Here, we assess ...
