Effect of Dietary Esterified Glucomannan on the Performance of Broiler Chickens During Experimental Aflatoxicosis

Abstract

Wade, M.R. and Sapcota, D. 2017. Effect of dietary esterified glucomannan on the performance of broiler chickens during experimental aûatoxicosis. Animal Nutrition and Feed Technology,.The amelioration effect of dietary esterified glucomannan (EGM) was studied in experimental aflatoxicosis using broiler chickens. Day-old chicks (n=270) were divided into 6 treatment groups, containing 45 numbers in each and the study was made in triplicates for 6 weeks. A control ration was prepared with conventional feedstuffs and an experimental diet was made from this ration after incorporating aflatoxin (AF) B 1 at 300 ppb. From experimental diet, three rations were prepared by mixing EGM at graded levels i.e., 0.025, 0.05 or 0.10%; whereas, the positive control diet had 0.05% EGM. Significantly (P<0.05) higher BW gain was recorded in the control as well as positive control birds as compared to all treated groups. Toxin-alone fed group showed significantly lowest BW. Feeding of EGM could partially improve the BW of toxin fed broilers. The feed consumption in toxin-fed groups were significantly depressed; however, there was partial improvement due to the supplementation of EGM in their diets. The feed efficiency was also inferior in the toxin-alone fed group; however, when EGM was supplemented there was significant (P<0.05), though partial improvement. The cost of feeding per kg live weight was found to be lowest in control group whereas highest in toxin-alone fed group; nevertheless, dietary EGM reduced cost of feeding. The highest performance index was noted in control group whereas the lowest in toxin-alone fed group. Among the various treatments, 0.10 per cent of EGM gave the best results.

Mitigative Potential of Novel Lactobacillus plantarum TISTR 2076 against the Aflatoxins-Associated Oxidative Stress and Histopathological Alterations in Liver and Kidney of Broiler Chicks during the Entire Growth Period

“…The incorporation of aflatoxins in chickens at a dose rate of 2 mg/kg resulted in reduction in body weight gain by 20–30% [ 19 ]. Similar results were also reported by [ 20 , 21 , 22 ]. When the Lactobacillus plantarum was used in combination with aflatoxins, it improved the feed intake and body weight.…”

Ameliorative effect of nanocurcumin and Saccharomyces cell wall alone and in combination against aflatoxicosis in broilers

“…The impairment of metabolizing capability may be the cause of AFB1's negative influence on growth parameters [ 27 ]. These findings are in harmony with previous studies reporting the negative effects of aflatoxin on growth performance [ 5 , 21 , 28 ]. Moreover, Mahrose et al [ 29 ] reported the deleterious effects of aflatoxin on the growth performance of Japanese quail.…”

“…Supplementing diets with yeast cell walls increases weight gains and improves feed conversion [ 20 ]. A trial of using a cell wall of yeast to minimize the adverse effects of aflatoxin-contaminated diets in broiler chicks resulted in a significant increase in BW gain and improved feed consumption [ 21 ].…”

The Efficacy of a Smectite-Based Mycotoxin Binder in Reducing Aflatoxin B1 Toxicity on Performance, Health and Histopathology of Broiler Chickens

“…Elevated levels of serum AST and GGT were observed in birds receiving 0.5 ppm of AF as compared to control group chickens, indicating considerable damage to the liver. Similar findings of elevated activities of serum enzymes due to aflatoxicosis were observed by many researchers [25][26][27]). Raju and Devegowda (2000) recorded no difference in AST levels in birds fed AF up to 0.3 ppm for 21 days [25].…”
