the aim of this study was to investigate the effects seaweeds gracilariopsis persica in diets on performance and tsh, t3 and t4 hormones in serum of laying quail. a total of 112 laying quails were randomly allocated into four dietary treatments (diets containing 0, 1, 3 and 5% seaweed) with 4 replicates of 7 birds each. the birds were fed on experimental diets for 12 weeks. eggs were collected ...

this experiment was conducted to evaluate the effects of using rice bran, combo multi-enzyme and probiotic (protexin) in diet on performance, egg traits, biochemical parameters and blood cells of commercial laying hens. this experiment carried out using 384 hi-line (w36) laying hens in a completely randomized design as factorial (2×2×2) arrangement with two levels of rice bran (0 and 10%), two ...

This experiment was conducted to evaluate the effects of different levels of dried aerial parts powderand extract of pennyroyal­ (Mentha pulegium) medicinal plant on performance, egg traits, blood biochemical and immunity parameters of laying hens. Two-hundred-fifty-two Hi-line (W36 strain) laying hens from 46 until 58 weeks of age were used in a completely randomized design in 7 treatments and...

Two experiments were conducted to evaluate the effects of different levels of dried lemon pulp (DLP) on performance of broilers and laying hens. In first experiment, 240 of broilers (Ross-308) were used in a completely randomized design with 4 treatments and 3 replicates (with 20 birds in each replicate) from 1 to 42 days. The amounts of DLP in diets were 0, 1.5, 3 and 4.5 percentage. In the se...

This experiment was carried out to evaluate different levels of peppermint (Mentha piperita) plant powder usage on feed conversion ratio (FCR), body weight (BW), feed intake (FI), body temperature, carcass parts (breast and thigh) and internal organs (liver, heart, gizzard) weights in broiler chicken. A total of 192 broiler chicken were randomly divided into 4 experimental treatments with 4 rep...

OBJECTIVE Turmeric (Curcuma Longa Linn) is a medicinal plant that contains curcumin. There is a growing interest in using curcumin powder (CP) as feed additives for antioxidative and antimicrobial properties to improve human health. This study was conducted to determine the appropriate levels of CP on blood parameters, immunity, and histology of jejunum in hens. MATERIALS AND METHODS A total ...

for determination the effect of lemon pulp levels and organic acid premix (globacid) on performance, carcass traits,immune system, biochemical parameters and intestinal morphology of broilers, 288 ross broilers were used in 3×2 factorial arrangement with three levels of lemon pulp (0, 1.5 and 3 percent) and two levels of globacid (0 and 0.1 percent) in a completely randomized design with six tr...

Generally, only a fraction of the mineral ingested by an animal is effectively absorbed, while most are bound to other components such as fibre and then excreted. In this study, faecal mineral composition differentials were used as indicators of mineral uptake by pullets supplemented varying levels of plantain ash in their daily rations for nine weeks. Plantain stalk and root base samples were ...
