The chicks were fed broiler starter from 0-6 weeks and broiler finisher from 7-8weeks. The additives were incorporated at levels recommended by the manufactures and the duration of the study was for 8 weeks.
The additives used did not bring about any significant improvement on growth of broilers to 8 weeks of age. However, neftin furazolidone and arsonic acid groups exhibited a better performance than the terramycin and control groups. The maximum per cent improvement in the 8th week live weight over the control was 6.48 given by the neftin furazolidone group. The best feed efficiency recorded in this study was 2.8 and this again was by the same group. The feed efficiency of arsenic acid group, terramycin group and the control were 2.9, 3.5 and 3.5 respectively. The mortality picture was not appreciably altered by the additives. A 3-hour-pre-slaughter fasting was found to be ruite satisfactory for emptying the crop and intestines. The neftin furazolidone and arsenic acid groups provided significantly higher dressed yields than the terramycin and control groups. The additives were effective in significantly improving the ready to cook yield in comparison to the controls. On an evaluation of the economic involved, it was found that a saving of 67 paise and 65 paise could be made in producing one kg live-weight in respect of neftin furazolidone and arsenic group respectively. However, terramycin was found to be uneconomical in this regard. Histo pathological examination of organ tissue reveald no injury. In the light of these findings, it was concluded that the incorporation of terramycin to broiler diets would not be economical in promoting broiler growth. However the possible presence of residues of these additives in broiler meat will have to be ruled out through controlled experiments before these additives are incorporated on regular commercial basis.
