| dc.description.abstract | An experiment was conducted at the Department of Poultry Science to investigate the effect of esterified glucomannan (E-GM) on alleviation of aflatoxicosis in broiler chicken. Day old broiler chicks numbering two hundred were reared under four different treatments with five replicates of ten chicks each. The four dietary treatments were T1 (control), T2 (1 ppm aflatoxin B1), T3 (0.1 per cent E-GM) and T4 (1 ppm aflatoxin B1 plus 0.1 per cent E-GM). Chicks were reared under standard managemental conditions up to six weeks of age. The broiler starter ration was fed from zero to four weeks and finisher ration from five to six weeks of age. Results of the study revealed that, inclusion of aflatoxin B1 (1 ppm) adversely affected the weekly body weight, weight gain, feed consumption, feed efficiency and overall livability during the experimental period. Serum concentrations of total protein, albumin and cholesterol in broilers fed 1 ppm aflatoxin B1 were significantly (P<0.05) depressed whereas; serum glucose level was significantly (P<0.05) elevated than control. Aflatoxin B1 caused significant increase in relative weights of liver, spleen and kidney. No significant difference existed between treatments for relative weights of bursa of Fabricius. The per cent dressed and eviscerated yields were significantly (P<0.05) decreased whereas giblet yield was significantly (P<0.05) increased in aflatoxin treated group. The per cent ready-to-cook yield, blood loss, feather loss and total loss were not influenced by dietary supplementation of aflatoxin B1. Supplementation of E-GM to toxin free diet caused no significant difference in the weekly body weight, weight gain, feed consumption, feed efficiency, relative organ weights, serum parameters and processing yields compared to control. Livability was better in T3 than control during the experimental period. Inclusion of E-GM in the aflatoxin B1 treated diet significantly counteracted the toxic effects of aflatoxin B1 on final body weight, cumulative weight gain and feed consumption and feed efficiency up to sixth week of age. Decreased level of serum total protein, albumin and cholesterol and increased glucose level due to aflatoxin feeding was restored to normal level. The altered relative weights of liver, spleen and kidney due to aflatoxin feeding were significantly improved by E-GM supplementation. The per cent eviscerated, dressed yield and giblet yield were restored by supplementation of E-GM to aflatoxin B1 treated feed. However no effect was observed on ready to cook yield, blood loss, feather loss and total loss compared to other treatments. The reduction in net profit per kg body weight caused by dietary aflatoxin was increased substantially by supplementation of E-GM to the contaminated feed. | en_US |
