avoparcin

01/01/1991 - "Supplementation of Avoparcin to the diets containing ROM improved weight gain and dressing percentage of the broiler chickens."
01/01/1991 - "The daily weight gain increased from 750 to 808 (experiment I), 553 to 649 (experiment II), and from 812 to 822 g per animal per day (experiment III) when avoparcin was added. "
06/01/1992 - "perfringens, and the feed conversion ratio at slaughter were significantly lower but the number of coliform bacteria, weight gain during the 3rd wk, and body weight of 4-wk-old chickens were significantly higher when the diets were supplemented with 7.5 mg avoparcin/kg feed. "
06/01/1992 - "Diets based on barley or corn without avoparcin supplementation were associated with high counts of Clostridium perfringens in the contents of the small intestine of the birds at the age of 2 to 4 wk. The weight gain of birds younger than 2 wk and the body weight of 4-wk-old birds were significantly lower, and the feed conversion ratio at slaughter was significantly higher, in birds on barley diets than in birds on corn diets. "
10/01/1990 - "Salt lick stones with avoparcin increased weight gain (58 and 96 g per animal and day). "

03/25/2000 - "The high rate of colonization of chicken products by vanA containing enterococci detected 6 months to 1 year after the banning of avoparcin as a growth promoter, supports other studies suggesting that the food chain could be a source of VRE colonization in humans and thus a source of VRE infections."
07/01/1997 - "The similar findings in the two studies provide evidence in favour of a causal association between the use of avoparcin and the occurrence of VREF on farms, and suggest that food animals constitute a potential reservoir of infection for VREF in humans."
02/01/1980 - "Infection spread more rapidly and more extensively through the avoparcin-fed groups than through the non-medicated groups."
04/01/1978 - " only five chickens in each group were experimentally infected so that the effect of the feed additives on infections acquired by contact could be monitored, avoparcin, lincomycin, nitrovin and tylosin again favoured colonization of the alimentary tract with the S. "

10/01/1979 - "Inclusion of avoparcin at 20 ppm in feed prevented necrotic enteritis in one group, but 10 ppm was only marginally effective. "
10/01/1979 - "The prevention of experimentally induced necrotic enteritis in chickens by avoparcin."
01/30/2004 - "When avoparcin was prohibited for use as feed additive in poultry in Norway on 31 May 1995, an increased incidence of Clostridium perfringens-associated necrotic enteritis (NE) and an increase in the use of antibacterial (AB) drug therapy in meat-type poultry was expected. "
02/01/2001 - "The study period was limited to the first 2.5 years after withdrawal of the in-feed antibiotic avoparcin, when necrotic enteritis was frequently seen. "
01/01/2019 - "When avoparcin was banned, broiler-feed was supplemented with the polyether ionophore narasin in order to control the diseases coccidiosis and the frequent sequela necrotic enteritis. "

01/01/1995 - "The results support the observation that avoparcin increases the body weight gain of animals during fattening."
01/01/1995 - "The dose of avoparcin was 0.75 mg/kg body weight. "
10/01/1985 - "Overall there was evidence that avoparcin increased body weight (5.8%), food consumption (2.5%) and efficiency of food utilisation (2.9%). "
10/01/1985 - "At day 49 significant interactions were detected between avoparcin and the anticoccidial compounds for body weight and food consumption. "
06/01/1992 - "perfringens, and the feed conversion ratio at slaughter were significantly lower but the number of coliform bacteria, weight gain during the 3rd wk, and body weight of 4-wk-old chickens were significantly higher when the diets were supplemented with 7.5 mg avoparcin/kg feed. "

11/01/2000 - "Community-acquired infections play an important role in spreading VRE because the use of avoparcin, an antimicrobial growth promoter in food animals, is strongly suggested to cause the emergence of VRE. "
