| The present study was conducted to evaluate the effects of feeding whole linseed on the laying performance and egg characteristics in laying hens kept at high ambient environmental temperatures (average 34 ºC; the diurnal temperature range 26 ºC to 41 ºC). Two hundred and forty 38-wk-old white Leghorn laying hens were fed diets containing 0, 5, 10 or 15% whole linseed (as a source of n-3 polyunsaturated fatty acids) for a period of 12 weeks. Egg production was recorded daily, while feed intake and egg characteristics were monitored on weekly basis. The results of the study demonstrated that egg production and feed intake decreased, while feed conversion ratio (FCR) per dozen of eggs increased (p < 0.05) with increasing dietary linseed levels.

| ABSTRACT The study was conducted to check the effect of emulsifier supplementation on growth performance of broiler birds on starter phase, from days 1 to 10. In the current study, a total of twelve hundred twenty-four Ross 308 broiler one day old chicks were used. Ross 308 broiler chicks were divided into two groups in such a way that each group had12 replicates, and each replicate had 51 birds. The duration of the current trial was of 10 days. Chicks were fed experimental diets with or without emulsifier supplementation. Daily feed intake, body weight, feed conversion ratio and nutrient digestibility were recorded. Mortality was recorded on a daily basis, and feed intake was also corrected for mortality. Data collected from the experiment was interpreted... |

| ABSTRACT The objective of this experiment was to investigate the effect of supplementation of an exogenous emulsifier (lyso-phospholipid) in the diet of growing broilers on growth performance and digestibility. A total of 1224 Ross-308 ten day old broiler chicks were distributed into two experimental treatments in such a way that each treatment had twelve replicates with fifty-one birds per replicate. Two experimental diets were formulated with and without emulsifier supplementation according to the nutrition standards of Ross 308. Feed intake and body weight gain of the broilers were measured on a daily basis and feed conversion ratio was also calculated. Nutrient digestibility was determined on the 25th day of age. Analysis of variance under completely... |
