“…It was also confirmed that Aureomycin produces significant growth performance when added to pigs’ diet. Aureomycin and penicillin improved the growth of fatting pigs by 10% and Terramycin (oxytetracycline) was as effective as Aureomycin at promoting growth [ 27 ]. Antibiotics also improve food conversion but have no effect on carcass quality.…”

Antibiotics have long been of great benefit for people, both in the medical treatment of human disease and in animal food where they improve the growth performance and feed utilization during animal production. Antibiotics as in-feed supplements affect all stages of pork production, including the gestation, nursing, growing, and finishing stages, although the effects show stage-dependent differences. However, the use of antibiotics in animal feed has become a worldwide concern. This review describes why sub-therapeutic levels of antibiotic additives in animal feed have become an integral part of animal feeding programs for more than 70 years, particularly in pork production. It also discusses the threat of the long-term use of sub-therapeutic levels of antibiotics in pork production. In recent years, the effectiveness of in-feed antibiotics has tended to decrease. This review analyzes this change from various perspectives. First, the equipment used at pig farms has improved dramatically and is more sanitary. Worldwide, more pig farms use pig farrowing crates, gestation crates, piglet nursery crates, flooring devices, piggery ventilation and cooler systems, automatic pig feeders, piggery heating equipment, and artificial insemination systems. In addition, scientists have replaced the use of antibiotics with organic acids, fermented mash, probiotics, prebiotics, minerals, oligosaccharides, enzymes, herbs/flavors, and protein/amino acids, and have improved management and husbandry techniques. In addition, animal welfare legislation has been aimed at improving the quality of the floors and living space, ensuring that animals have permanent access to fresh water, and setting a minimum weaning age. Finally, the prospects and the possibility of replacing antibiotics in pork production are described, in line with recent research results.

“…From the results, it was observed that antimicrobials were the efficient agents for feed and growth improvement in adult pigs, as well as the whole growth-finished phase, and reduced death and disease conditions mostly in juvenile pigs. The death rate can be doubly high in the farm environment compared to research locations where the amenities are usually clean, the disease load is less, and the atmosphere is less traumatic (Luecke et al, 1951). The advantageous effects of antimicrobials on body mass growth were accompanied by improved feed consumption effectiveness, enhanced desire for food, and extra common exterior of the fur hair and hide.…”

“…In swine production, antibiotics as growth promoter (AGP) have been used since the 1950s [ 1 , 2 ]. AGP can suppress or inhibit the proliferation of certain microorganisms, preventing or mitigating the severity of disease caused by microbial infection [ 1 , 3 , 4 ].…”

“…AGP can suppress or inhibit the proliferation of certain microorganisms, preventing or mitigating the severity of disease caused by microbial infection [ 1 , 3 , 4 ]. In addition, the reduction in pathogenic microbes would enhance intestinal health by reducing the inflammatory response and oxidative stress, ultimately improving the efficiency of nutrient utilization and promoting growth performance [ 2 , 5 ]. However, the residual antibiotic in animal products and the prolonged use of antibiotics in animal feeds can increase microbial resistance [ 6 , 7 ].…”

This study aimed to investigate the effects of phytobiotics on the intestinal health and growth performance of pigs. Totals of 40 newly-weaned pigs with 6.4 ± 0.3 kg BW (Exp. 1) and 120 growing pigs with 27.9 ± 2.3 kg BW (Exp. 2) were allotted in RCBD in a 2 × 2 factorial arrangement. The factors were: antibiotics as growth promoter (AGP) and phytobiotics (PHY). Pigs were fed experimental diets during 21 d (Exp. 1) and 42 d (Exp. 2). Growth performance, health parameters, and nutrient digestibility were evaluated. In Exp. 1, AGP diet increased (p < 0.05) ADG and G:F compared with a diet without AGP or PHY and a diet with AGP combined with PHY. PHY decreased (p < 0.05) TNF-α and IgG in the jejunum and protein carbonyl in plasma, whereas it increased (p < 0.05) the villus height. In Exp. 2, AGP or PHY diets increased (p < 0.05) ADG, ADFI, and G:F compared with a diet without AGP or PHY and a diet with AGP combined with PHY. PHY decreased (p < 0.05) IgG and PC in plasma. Collectively, AGP and PHY improved growth performance by reducing oxidative stress and enhancing immune status and jejunal morphology. However, the combinational use of phytobiotics with antibiotics suppressed their effect.
