Summary: | In the conditions of farms of the Republic of Belarus there were presented the results of collaborative scientific research with specialists of breeding farms during which there were created herds of sows in the amount of 1007 animals with productivity corresponding or exceeding the requirements of the target standard: multiple fetation – 12,1 animals; age of reaching 100 kg of live weight – 174,2 days; average daily weight gain – 826 gram, forage expenses – 3,30 forage units, back fat thickness – 25,7 mm, weight of ham – 11,1 kg. The obtained high genetic potential was realized through the sale of 2747 of breeding young animals (992 boars and 1755 gilts). The complex assessment of pigs of Belarusian large white breed showed a high level of their development and productivity in the farms of the Republic. Thus, the average of boars and sows at the age of 36 months and older exceeded the requirements of the elite class: live weight - 326.6 kg (elite class - 300 kg) and 263.9 kg (240 lbs), body length - 182.1 cm (180 cm) and 167.9 cm (165 cm). Multiple fetation of sows, corresponding to the target standard of efficiency, was equal to 12.1 piglets and exceeded the requirements of the elite class on 1.1 piglets (or 10.0%), milkiness - 57.35 kg (5.35 kg or 10.2%, respectively). |
