Abstract

In the present study, offsprings of 14 sows were used to evaluate the effect of fermented milk substituted for creep feed to analyze its effect on growth performance, diarrhea score and blood profiles. The piglets of sows were randomly allocated into 1 of 2 treatments (1 treatment separated piglets of 7 sows). The dietary treatments includes: CF (creep feed) and FM (fermented milk). The CP and FM diets were given from 3 d after piglets were born to the day of weaning (21 d after piglets were born). No significant difference (P>0.05) were observed in number of born piglets, weaning pigs, survival rate, body weight of piglets at d 0, 7, 14, and 21, ADG and ADFI. At d 21, piglets fed with CP had a higher (P<0.05) IgG compared with piglets fed with FM. No significant difference (P>0.05) was observed in WBC among the treatments at d 21. At d 6, piglets fed with CP had a lower (P<0.05) number of diarrhea piglets compared to piglets fed with FM. In conclusion, FM substituted for CP had no adverse effect on growth performance in lactating piglets.

본 연구는 포유자돈용 발효유의 급여가 포유자돈의 생산성, 설사지수, 혈액특성에 미치는 영향을 알아보기 위해 시험을 실시하였다. 사양 시험은 3산차 모돈($Landrace{\times}Yorkshire$)은 14두를 공시하여, 2처리구 처리당 7두로 분만 후 부터 이유시까지 3주간 사양시험을 실시하였다. 시험설계는 1) CF (Creep feeding), 2) FM (fermented milk)로 실시하였다. 포유자돈용 발효유의 급여가 생산성에 있어서 유의적 차이는 보이지 않았으나, 생시체중이 입붙임 사료구와 비교하여 수치상 낮았으나, 이유체중에서는 포유자돈용 발효유를 급여한 구가 300 g 증가한 결과를 나타내었다. 포유자돈용 발효유의 급여시 설사지수에 있어서는 처리구간 유의적 차이가 없었다. 혈액 특성에 있어서는 혈액내 백혈구 함량에 있어서는 처리구간 유의적인 차이를 나타내지 않았지만(P>0.05), 혈액 내 면역 글로불린 함량에 있어서는 입붙임 사료를 급여한 처리구가 포유자돈용 발효유를 급여한 처리구보다 높게 나타났다(P<0.05). 이와 같은 결과는 입붙임 사료는 탄수화물, 단백질, 지방 및 면역관련물질을 함유하고 있으나, 본 연구에서 사용된 포유자돈용 발효유는 장내 미생물균총에 유익한 영향을 미치는 유산균은 함유하고 있으나, 다른 면역물질 및 첨가제를 함유하고 있지 않아 혈액 면역세포에 영향을 미치지 않은 것으로 판단된다. 결론적으로 포유기간 동안 입붙임 사료를 대신하여 포유자돈용 발효유를 급여하여도 생산성에 부정적인 영향을 미치지 않는 것으로 판단되며, 입붙임 사료를 대체할 수 있는 물질로 급여 가능할 것으로 사료된다.
