Sun-Dried Sugarcane Press Mud Could be a Prospective Feedstuff for Swine Production

Conventional swine production evolved to routinely use antimicrobials, and common occurrence of antimicrobial-resistant Salmonella has been reported. There is a paucity of information on the antimicrobial resistance of Salmonella in swine production in the absence of antimicrobial selective pressure. Therefore, we compared the prevalence and antimicrobial resistance of Salmonella isolated from antimicrobial-free and conventional production systems. A total of 889 pigs and 743 carcasses were sampled in the study. Salmonella prevalence was significantly higher among the antimicrobial-free systems (15.2%) than the conventional systems (4.2%) (odds ratio [OR] = 4.23; P < 0.05). Antimicrobial resistance was detected against 10 of the 12 antimicrobials tested. The highest frequency of resistance was found against tetracycline (80%), followed by streptomycin (43.4%) and sulfamethoxazole (36%). Frequency of resistance to most classes of antimicrobials (except tetracycline) was significantly higher among conventional farms than antimicrobial-free farms, with ORs ranging from 2.84 for chloramphenicol to 23.22 for kanamycin at the on-farm level. A total of 28 antimicrobial resistance patterns were detected. A resistance pattern with streptomycin, sulfamethoxazole, and tetracycline (n = 130) was the most common multidrug resistance pattern. There was no significant difference in the proportion of isolates with this pattern between the conventional (19.5%) and the antimicrobial-free systems (18%) (OR = 1.8; P > 0.05). A pentaresistance pattern with ampicillin, chloramphenicol, streptomycin, sulfamethoxazole, and tetracycline was strongly associated with antimicrobial-free groups (OR = 5.4; P = 0.01). While showing the higher likelihood of finding antimicrobial resistance among conventional herds, this study also implies that specific multidrug-resistant strains may occur on antimicrobial-free farms. A longitudinal study with a representative sample size is needed to reach more conclusive results of the associations detected in this study.

Public health officials and physicians are concerned about possible development of bacterial resistance and potential effects on human health that may be related to the use of antimicrobial agents in livestock feed. The focus of this research is aimed at determining the economic effects that subtherapeutic bans of antimicrobials would have on both swine producers and consumers. The results show that a ban on growth promotants for swine would be costly, totaling $242.5 million annually, with swine producers sharing the larger portion in the short run and consumers sharing the larger portion in the long run.

Large Numbers

Gastrointestinal infections associated with E. coli represent a serious problem for neonatal pigs. These bacteria are present in the sow’s intestine in large numbers but increase dramatically just prior to farrowing due to stress occasioned by movement and parturition (Maclean and Thomas, 1974). Consequently, just 24 hours after farrowing, E.coli are found in high numbers (over 108/g) in the faeces of piglets. However, at this stage of its life the piglet is not equipped to deal with such a large microbial load and unless immunological assistance is provided, they have very little chance of survival. In pigs, all immunological assistance at birth is concentrated in the mother’s colostrum. Thus elimination, or at least minimizing, all the factors which negatively affect the sow’s ability to produce sufficient amount of milk becomes essential challenge of each efficient swine production. The main aim of this study was to investigate the potential of fermented liquid feed (FLF) to control the pathogen load within the piglet’s environment by reducing the rapid E. coli multiplication in sows associated with farrowing. The possible laxative effect of FLF, in order to prevent constipation and the problems it causes during farrowing, was also examined.
