Impact of chlorine dioxide as water acidifying agent on the performance, ileal microflora and intestinal histology in quails

Abstract. The present study was planned to investigate the effect of different levels of chlorine dioxide on the performance, gut microbiota and intestinal histology of quails. For this purpose, 300 day-old healthy quail chicks were randomly placed in 20 specially designed pens (15 birds/pen) with water troughs containing chlorine dioxide at the level of 0.00 (DW-0.00), 0.3 (DW-0.3), 0.4 (DW-0.4) and 0.5 ppm (DW-0.5) in replicated fashion (5 replicate/treatment) for 28 days. Weight gain, feed conversion ratio and dressing percentage increased significantly (P

Nutritional Effect of Flaxseeds on Cholesterol Profile and Fatty Acid Composition in Egg Yolk

ABSTRACT This experiment investigated the effect of a supplementary dietary source (flaxseed) on egg yolk cholesterol contents and fatty acid profile. Flaxseeds at three different levels (5, 10, and 15%) were supplemented to 84 Rhode Island Red × Fayoumi cross layers during 21–24 weeks of age. The birds were divided randomly into four groups. Flaxseeds were supplemented in the diet at the level of 5% (FS-5), 10% (FS-10), and 15% (FS-15), and one group served as the control (FS-0). Cholesterol content of eggs was not significantly affected by flaxseed. The amount of monounsaturated fatty acids was significantly decreased with the increase in the flaxseed level, and the highest reduction was observed in FS-15. The highest total polyunsaturated fatty acid (PUFA) and total omega-3 PUFA were recorded in FS-15. These findings reflect that unsaturated healthy fatty acid content in poultry eggs can be increased with dietary supplementation of flaxseed.

Lower Illeal Microflora and Growth Performance of Broilers Supplemented with Organic Acid Blend (Aciflex®) During Starter Phase

Organic acids can be replaced as effective feed additives with antibiotics. Organic acids and their salts have the potential to retard the development of pathogens in the diets and thus maintain the microbial equilibrium in the gastrointestinal tract. In this study, 225 day-old broiler chicks were used for a period of 21 days in order to examine the effect of different levels of organic acids (OA) on performance of broiler. The following parameters: feed intake, water consumption, weight gain, feed conversion ratio (FCR), total Salmonella and E. coli count, weight of visceral organs and length of intestine were studied during starter phase. The experimental chicks were divided into five groups (n=5, 15 birds/replicate). The chicks in control group OA-0 were offered clean drinking water having no organic acid while those in group OA-1, OA-1.5 and OA-2 were given 1, 1.5 and 2ml of organic acid blend. Each litter of drinking water contained citric acid 80g, lactic acid 52g, phosphorous 92g, copper sulphate 10g, respectively. Organic acid (2ml/L) supplementation significantly (p<0.05) increased feed intake (405.37g), weight gain (218g), FCR (1.42), weight of liver (0.02g) and gizzard (0.03g). Similarly in group OA-2 organic acid supplementation significantly decreased (p<0.05) the total salmonella (1.6x10 7 ) and E. coli (1.7x10 7 logCFU/g) count in intestinal contents. From present findings it was concluded that organic acid supplementation at level of @ 2ml/L in drinking water had beneficial effect on broiler performance and also decreased the colonization of intestinal bacterial counts.
