브로일러에 대한 lactobacillus casei(TSC-66)의 성장 촉진 효과

The effect of lactobacillus casei(TSC-66) for the growing promotion in broiler chicken

Lactobacillus casei TSC-66, a new probiotics, was adiministered to elucidate its effect for the growing promotion in broiler chickens through 2 experiments. Naracin, virginiamycin and streptococcus faecium were also applied for comparison with L. casei TSC-66. By the supplementation of L. casei TSC-66 to basal feedstuffs, body weight gains of chicks were improved up to 3.4%-3.8% and the addition of antibiotics (80㎍ of naracin and 10㎍ of virginiamycin/g of feedstuffs) to L. casei TSC-66 showed further increase in body weight gain up to 6.0%. Feed conversion ratios were improved up to 0.3%-3.1% when compared to those results of controls and the addition of antibiotics showed little enhancement. It is concluded that the administration of L. casei TSC-66 can improve the growing promotion of broiler chicken and can reduce or replace the significant amount of antibiotics used for the promotion of animal growth.
