The Use of Bambermycins (Flavomycin®) and Halofuginone (Stenorol®) in Diets for Growing Turkeys

Abstract

Experiments were conducted at three geographic locations in the United States (Arkansas, Colorado, and Minnesota) to examine the response of Large White turkeys to bambermycins in the presence of halofuginone. Each location utilized diets commonly used at that station for growing turkeys. All diets contained 3 ppm halofuginone, and were supplemented with 0, 1, 2, or 4 g bambermycins/ton (908 kg). Bambermycins was fed from day-old to marketing; halofuginone was removed from feed for 3 days prior to marketing. Although there were some significant differences in final body weights or feed utilization among locations, there were no significant interactions of location X bambermycins. Body weight of males was significantly (P less than .05) improved by the addition of 2 g bambermycins/ton. Body weight of females was significantly (P less than .05) improved by all levels of bambermycins; 4 g/ton stimulated significantly (P less than .05) superior gains than 1 or 2 g/ton. When body weight for both sexes was combined, bambermycins at 2 and 4 g/ton resulted in significant (P less than .05) improvements in body weight. Feed utilization, expressed as units of feed per unit of gain, was not significantly influenced by dietary treatment. There were no significant differences in mortality related to location or dietary treatment.

Effects of organic acid and probiotic on performance and gut morphology in broiler chickens

“…Antibiotics have been used for several decades to combat certain pathogenic diseases in farm animals and improve their growth. The inherent dangers in this include increased resistance by pathogens to antibiotics, and residual amounts of antibiotics in animal products, which have been reported by several authors (Truscott & Al-Sheikhly, 1977;Miles et al, 1984;Waldroup et al, 1985;Hernandez et al, 2006;Pirgozliev et al, 2008). Although the inclusion of antibiotics in feed has been banned in the EU countries, such legislation has yet to take place in many other countries, including Nigeria, where antibiotics are still used in animal feeding.…”

Effect of the anticoccidial agents halofuginone and monensin when given with growth promoting antibiotics upon the control of coccidiosis in the turkey

“…However, at 10 weeks, bodyweight was greater in poults given HAL with BAM than in poults given HAL (or MON) with BAC. The growth rate of turkeys medicated with HAL or MON is significantly improved by supplementation with BAM or BAC (Waldroup et al, 1985(Waldroup et al, , 1993. These antibiotics are thought to stimulate growth by their antibacterial action against gram-positive microorganisms which interfere with the absorption of nutrients (Eyssen & Somer, 1963).…”

“…Differences in the prevalence of resistance to BAM and bacitracin in various bacteria obtained from chicken farms have been reported (Landon, 1992). Many studies have been conducted to investigate the growth rate and feed efficacy of turkeys fed antibiotics (reviewed by Waldroup et al, 1985;Caston & Leeson, 1992) with improvements recorded in some experiments and not in others. It has been suggested that variations in efficacy reflect differences in management practices, housing conditions, bird type, age and sex.…”
