This study was conducted to evaluate the effects of dietary nettle (Urtica dioica) medicinal plant supplementation on growth performance, carcass traits, and blood biochemical and immunity parameters in female broiler chicks. A total of 300 (Ross-308) broilers were randomly allocated into one of the following dietary treatments: 1) control, " # " $ % # " $ % # " $ % # " $ % $ & ' $ chicks per p...

An experiment was carried out to evaluate and compare the effects of organic and inorganic selenium (Se) sources on broiler male birds (Ross 308). Uniform broiler male chicks divided in to five groups with six replicates were fed with either normal feed (without supplemental Se, negative control), 0.25 ppm of inorganic Se, 0.5 ppm of inorganic Se, 0.25 ppm of inorganic Se + 0.25 ppm of organic ...

________________________________________________________________________________ Abstract Bonsmara type steers were used to determine the effect of dietary zilpaterol hydrochloride (ZH) in combination with different dietary crude protein (CP) levels (100, 120 and 140 g CP/kg) on growth performance and meat quality. Treatment groups (T) consisted of 12 steers each. T1 – 100 g CP/kg + 0.15 mg ZH/...

Marigold flower extract, a natural pigment, was used to determine its effect on carcass and skin pigmentation, immunity and growth performance of broiler chickens. Two hundred and forty 1-day-old Arbor Acres broiler chicks were randomly distributed into four treatment groups with six replicates in a randomized block design. Birds were fed basal diet for 42 d with or without supplementation of m...

This experiment was conducted to investigate the effects of leucine (Leu) supplementation on performance and carcass traits broilers along with re-evaluation standardized ileal digestible (SID) Leu requirement broiler chicks days 0-14. Birds were fed seven experimental diets SID levels 16.3 (basal), 17.3, 18.3, 19.3, 20.3, 21.3, 22.3 g/kg. Some 280 male randomly assigned dietary treatments in a...
