Pig Breeds (GF24) Introducing to Central Vietnam and Reproductive Performance

Abstract

Abstract:The aim of this study was to characterize the reproductive performance of new pig breed introduced to Central Vietnam. The data were 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 female breeding pigs imported from US for Vietnam through GreenFeed Asia were intended for reproductive performance. Results obtained for first coming heat, first mating, first litter farrowing age, pregnancy time and dry sow were as follows: 166.2 ± 2.94, 200.44 ± 2.14, 133.79 ± 2.29, 317.75 ± 2.19, 117.31 ± 0.31 and 8.27 ± 0.86 d, respectively. The average number of piglets born alive and stillbirths per litter were 11.58 ± 0.52 and 0.65 ± 0.27, respectively; both traits were affected by the parity of the sows. The individual weight at birth of piglets was 1.38 ± 0.12 kg and the number of weaned piglets was 9.58 ± 0.53. The feeding in the farms was characterized by using commercial feed (80%) and agricultural remainder (20%) as balanced feed. As a conclusion, this breed offers a potential progress in livestock for rural and industrial areas and is a contribution to the development of pig husbandry in Vietnam.
