EFFECT OF THE USE OF MOS AND ORGANIC ACIDS IN PERFORMANCE PIGLETS
Abstract
The production chain of swine has been developed to meet the consumer market , seeking a more lean meat and produced cleanly. Faced with this demand , key areas of swine as genetics, nutrition , health , ambience , animal welfare, management of costs and environmental management are increasingly studied and debated to the organs concerned . Have advances in the field of nutrition has also contributed to a cleaner animal production through the use of enhancers efficiency as prebiotics and organic acids in the diets of pigs as potential substitutes for conventional growth promoters . The mannan oligosaccharides ( MOS ) along with organic acids , are able to maintain the integrity of the digestive tract , by benefiting the multiplication of beneficial bacteria and also in the specific case of MOS , act as adsorbents of pathogenic bacteria , preventing their adhesion in the intestinal epithelium and causing their elimination . Since these effects improve the absorption of nutrients with gains in production rates . Given the above , the objective of this study is to evaluate the effects of MOS and organic acid in the performance parameters of piglets during 15-30 Kg The experiment will be conducted in the UEP on Swine Campuses Two Neighbors - UTFPR . Crusaders 18 pigs with an initial average weight of 15kg with 50 days of age , distributed in a completely randomized design with two treatments will be used : T1 - basal ration T2 - ration + 0.2% MOS + organic acid , with 3 replications and 3 animals per experimental unit . The parameters evaluated were weight gain , feed intake , feed conversion , stool consistency and feed cost per kg of produced pig . There was no difference ( P > 0.05 ) on growth performance and fecal consistency between treatments . However , the cost per kg pig was highest in treatment 2 (with additives ) compared to Treatment 1 (control). In the conditions of the present study was conducted , it can be concluded that the use of MOS and organic acids did not improve the productive and economic performance of starter pigs .
