In comparison to the vapour gas-compression refrigeration, magnetic heat-pumping near room-temperature is regarded to be an alternative technology due to its high energy efficiency and environmentally friendly solid-state cooling materials. The magnetic heat pump technology utilizes the magnetic field induced temperature change, which is based on the magnetocaloric effect (MCE).

Lactic acid bacteria widely used in food preservation at refrigerator temperatures due to their ability produce high amount of hydrogen peroxide and/or other antibacterial substances at refrigerator temperatures to inhibit food-borne pathogens and psychrophilic spoilage microorganisms. In order to improve of bio-preservation efficacy of Lactobacillus acidophilus GH 201 mutations causing resistance to rifampicin (rif) were used.

Quantitative bacterial culture (QBC) is the gold standard for diagnosing canine urinary tract infections. Current guidelines recommend QBC within 24h of urine collection and that unpreserved urine is refrigerated until culture. However, temperature-controlled transport is rarely feasible, indicating a need for alternative storage during transport of urine from primary veterinary practices to the microbiology laboratory.

In the present study, 3 mongrel dogs were taken for semen collection. Total of 18 ejaculates were collected, 6 from each dog by digital manipulation. All the collected samples were randomly divided into three Groups viz. Group I (Non-extended semen), Group II (Semen extended with egg yolk tris citrate fructose extender) and Group III (Sperm pellet extended with egg yolk tris citrate fructose extender) and kept at refrigeration temperature (4oC). In Group III semen is centrifuged at 720 x g for 5 minutes by centrifuge machine Tarsons Spinwin MC05-R for making of sperm pellet.
