PIG BREEDS (GF24) INTRODUCING TO CENTRAL VIETNAM AND REPRODUCTIVE PERFORMANCE
Abstract
The aim of this study was to characterize the productive performance of new breed introducing to Central Vietnam. The data compilation was collected on farm by field-studies with 30 individuals, during a period of one year to record and register productive and reproductive indicators. The GF24 breeding stock girls imported from US for Vietnam through Green feed Asia, which were intended for reproductive performance. Results conducted for first coming heat, first mating, first litter farrowing at age, pregnancy time and dry sow were earlier than other exotic breeds. Results conducted in reproductive performance, 166.2 ±2.94 days, 200.44 ±2.14 days, 133.79 ± 2.29 days, 317.75 ± 2.19, days 117.31 ± 0.31days and 8.27 ± 0.86 days, respectively. The average number of piglets born alive per litter were 11.58 ± 0.52, both traits were affected by the parity of the sow. The individual weight at birth was 1.38 ± 0.2 kg and the number of weaned piglets 9.58 ± 0.53. The feeding in the farms was characterized by commercial feed (80%) and agricultural remainder (20%) as balanced feed. This breed will offer a potential livestock for rural and industrial areas and contribution of pig husbandry in Vietnam.
Key words:GF24 pig breed, reproductive performance, adaptation, Central Vietnam
