EFFECTS OF SUPPLEMENTATION PROBIOTIC PRODUCTS AND NEWBORN PIGLET WEIGHTS ON SOME PRODUCTION CRITERIA OF THREE BLOODS HYBRID (DR X YL) PIGS

Abstract

This study is aimed to evaluate the role and effect of the probiotic (Clostat HC Dry) supplementation (Bacillus subtilis living cells and components: Calcium carbonate, silica and sodium propionate salts) provided by Kemin Product Specification and newborn piglet weights on performance of fatteners 3 blood hybrid pigs (Duroc x Yorkshire - Landrace). Probiotic was added to complete feed. The experiment was conducted on a total of 18 sows (sows with relatively similar farrowing days), with litter between the second to fourth, and a total of 236 piglets. Without adding and with additional supplementation of probiotic preparations Clostat HC Dry to the feed which fed for pigs with the 3 different of newborn weights (low, medium, and high), to make a total 2 x 3 = 6 treatments.

Supplement of probiotic Clostat HC Dry at 0.5 grs per 1 kg of feed for fatteners from early feeding practice to 150 days of age had a good effect on weaning weight, slaughter weight and economic performance:: The livability of pigs from newborn to weaning and slaughter were 100%. The diarrhea suffering was 10.00 - 23.33% at the stage of suckling period and there was no diarrhea syndrome showed in the post-weaning period. The weight of pigs up to 150 days old were 102.33 - 124.33 kg, the difference with feeding non-probiotic supplement was statistically significant. Feed conversion ratio were 2.11 - 2.25. Direct costs per kg of live body weight of fatteners at 150 days of age with addition of probiotic supplement to feed was average at 42,100,000 VND,  equivalent to 95.35% comparing to control fatteners fed non-probiotic. There was also the positive significant correlation between newborn weights and the production criteria as the higher the body weight of newborn piglets, the higher the body weights and lower the feed conversion ratio of fatteners at 150 days of age.
