Abstract
    Growth of vietnamese pigs has taken some measure among small breeders in Romania. Information on the breeding performance and qualities of these pigs is contradictory and sometimes exaggerated. The present paper aims to study reproductive and growth performance in 2 of the most widespread Vietnamese pig breeds in Romania: Mong Cai and Co. Reproduction performances were studied on 10 sows, 5 from each breed, for 3 litter. The production performance was performed on 40 pigs, male castrated and females, 20 of each breed, who were followed from weaning until 1 year of age. Results obtained for age of first estrus, litter size, weight of first day, weight of weaned pigs, parturition interval and number of parturition on year were as follows: 4-5 months, 6 – 8 piglets, 0.41 kg, 3-4 kg, 6 -7 months, 1.6 – 1.7 partutition for breed Co and 6-8 months, 7 – 12 piglets, 0.45 kg, 5 - 6 kg, 5 - 6 months, 1.5 - 2 partutition for breed Mong Cai. Similarly, growth results are higher at breed Mong Cai versus breed Co. As a conclusion, this breeds have performance for reproduction and breeding inferior to local breeds and we do not recommend them to grow.
