narasin

03/01/1979 - "With most species studied, 40 and 60 ppm narasin was not as efficacious as 80 or 100 ppm. The maximum numerial improvement in weight gain and feed conversion ratio was with 80 ppm narasin. "
07/01/1988 - "Medication with narasin resulted in a significant reduction in lesion scores and significant improvement in weight gain and feed:gain ratios when compared with scores and gain of nonmedicated controls for both seeded and nonseeded pens. "
07/01/1988 - "tenella plus intestinal species of coccidia, when medicated with 80 ppm narasin had weight gains significantly greater than those of birds medicated with 60 ppm narasin. "
03/01/1979 - "Feeding ration medicated with 60, 80, or 100 ppm narasin significantly improved weight gains during the periods of D 0 to D7 and D 0 to D 14 (D 0 = day of inoculation with sporulated oocysts), compared with the weight gains in corresponding inoculated groups fed unmedicated feed. "
09/01/1980 - "Analysis of pooled data from these trials indicated that a level between 48 and 96 ppm narasin would provide the optimum, depending on whether maximum weight gain or optimum feed conversion ratio was desired. "

07/01/1989 - "Narasin reduced the severity of cecal coccidiosis as measured by a reduction in cecal lesions and an improvement in bird performance. "
10/01/1981 - "Efficacy of narasin against hepatic and intestinal coccidiosis in rabbits."
11/01/2018 - "Monteban® G100, containing narasin, is intended for the prevention of coccidiosis in ducks for fattening at a dose range of 60-70 mg/kg of complete feed. "
04/25/2018 - "Anticoccidial vaccination is a better strategy for controlling coccidiosis than feeding narasin, due to not only greater growth performance, but also the lower Met supplementation. "
01/01/2005 - "They contain narasin and are used for the prevention of coccidiosis in chickens. "

01/01/1978 - "Narasin is active in vitro against gram-positive bacteria, anaerobic bacteria, and fungi and is effective in protecting chickens from coccidial infections."
01/01/2011 - "Time-of-addition studies of narasin-treated, DENV2-infected Huh-7 cells suggested narasin to be involved in inhibiting the post-entry stages of viral replication during DENV infection. "
04/01/1981 - "Narasin effectively controlled infections that were inadequately controlled by the anticoccidial drugs to which the strains were resistant. "
07/01/1988 - "Weight gain improvement decreased at narasin concentrations greater than or equal to 100 ppm. Results of these studies confirm the effectiveness of narasin in controlling coccidial infections produced by recent field isolates of the pathogenic species of chicken coccidia."
03/01/1979 - "Narasin at 80 or 100 ppm was generally more effective in controlling individual or mixed species infections of coccidia than 99 ppm monensin."

01/01/2001 - "This study thus provides evidence that narasin is effective in the prevention of necrotic enteritis in broiler chickens."
01/01/2001 - "The efficacy of narasin in the control of necrotic enteritis (NE) was investigated in a floor pen study of 2000 broiler chickens using a Clostridium perfringens feed inoculum challenge model. "
01/01/2001 - "Efficacy of narasin in the prevention of necrotic enteritis in broiler chickens."
01/01/1992 - "Two trials were conducted to study the effects of a competitive exclusion (CE) product BROILACT and the anticoccidial narasin on the incidence of necrotic enteritis (NE), the numbers of Clostridium perfringens (CP) in the caeca of broiler chicks and the performance of the birds. "
03/01/2003 - "The efficacy of bacitracin methylene disalicylate (BMD) in the management of necrotic enteritis (NE) when fed in combination with narasin was investigated in a floor-pen study of 2,000 broiler chickens using a Clostridium perfringens inoculum challenge model. "

01/01/2001 - "Among challenged birds, those fed narasin had significantly (P < 0.05) higher mean body weight and improved feed efficiency at days 21 and 41 and significantly (P < 0.01) lower cumulative NE mortality at day 41 than unmedicated. "
01/01/2023 - "In Exp. 1, 40 rumen-cannulated Nellore steers [initial body weight (BW) = 231 ± 3.64 kg] were blocked by initial BW and assigned to one of the five treatments as follows: Control (CON): no feed additive in the basal diet during the entire feeding period; Sodium monensin (MM) at 25 mg/kg dry matter (DM) during the entire feeding period [adaptation (days 1-21) and finishing (days 22-42) periods]; Narasin (NN) at 13 mg/kg DM during the entire feeding period (adaptation and finishing periods); Sodium monensin at 25 mg/kg DM during the adaptation period and narasin at 13 mg/kg DM during the finishing period (MN); and narasin at 13 mg/kg DM during the adaptation period and sodium monensin at 25 mg/kg DM during the finishing period (NM). "
10/01/1985 - "This indicated that the increases in body weight and food consumption obtained with avoparcin were greater with some anticoccidial compounds (lasalocid and salinomycin for body weights and lasalocid for food consumption) than with others (monensin and narasin for body weights and monensin, narasin and salinomycin for food consumption).
