"Nature is for maintaining species; what we do is make fillets," said Danilo Sosa, a technician at the tilapia breeding pens of Nicanor Fish Farms, outside Managua, Nicaragua, plopping a tilapia used for breeding on a wooden table and scanning the chip in its gut that identifies its breeding line.
During captivity (both whilst housed in breeding pens and lab cages) each water vole was fed ¼ fresh apple daily with chopped vegetables and dried rodent food (Russell Rabbit, Supreme Petfoods Ltd., Waterlooville), with access to water provided ad libitum via standard lab water bottles which were replenished daily.
One week before transportation to Oxford the voles were captured by hand from their breeding pens, and split into smaller, same-sex groups in standard lab cages, as per standard practice for captive-bred water voles destined for reintroduction programs.
Fortunately, the use of unitized breeding pens, coupled with detailed pedigree records in the Australian crocodile industry, has provided the pedigrees and complementary DNA resources necessary for the construction of the first crocodilian genetic map.
There would be arched windows, he said, and a gymnasium, two greenhouses, workshops and a sheep-breeding pen.
The aim of this study was to investigate potential risk factors for two groups of Salmonella sp serotypes using pen faecal samples from breeding pig holdings representative of the Portuguese pig sector.
The aim was to search for potential risk factors for shedding from two different groups of Salmonella serotypes using pen faecal samples from herds with breeding pig representative of Portuguese reality.
In each herd only the pens with breeding pigs over six months of age were randomly selected.
The variables - region of the herd, size of the herd, source of semen, rodents control, number of pigs per pen, age of breeding sows, breeding sector room, source of feed and use of antibiotics - were selected to enter the multivariable model.
