background & aim: medicinal plants is very potential to be used as a supplementary feed as well as feed additive in broilers.this experiment was conducted to investigate the effects of milk thistle (mt) and thyme seeds (ts) on the performance in broilers. experimental: in this study, 160 one-day-old (ross 308) male broiler chicks were divided randomly into four major groups with 4 replicate...

Bioavailability of dietary folate might be impaired by the polyglutamate chain to which approximately 70% of dietary folates are bound. This chain must be removed enzymatically in the intestine before folate is absorbed as a monoglutamate. To increase formation of monoglutamate folate in vegetables, the vegetables were subjected to various processing treatments. Treatments included freezing (-1...

one-hundred-sixty-eight 28-wk-old hy-line layers (w-36) were used to evaluate the effect of different levels of linseed (ls) and safflower seed (ss) on antibody titter, blood and yolk cholesterol, yolk fatty acid content and the ratio of omega-6/ omega-3. hens were randomly assaigned in a compeletly randomised design each 3 replicates of 8 hens. they were fed diets contained 0, 4, 7 and 10% ls ...

We conducted two experiments evaluating the lysine requirement of 91- to 113-kg gilts. Gilts (PIC L326 x C-22) with initial body weights of 42 (Exp. 1) or 39 kg (Exp. 2) were blocked by weight in a randomized complete block design. Experiment 1 included 105 gilts, with seven gilts per pen and five replications (pens) per treatment. Experiment 2 included 125 gilts, with eight gilts per pen and f...

This experiment was undertaken to evaluate the effect of dietary level of artichoke (Cynara scolymus) on growth performance and immune response of broilers under heat stress (HS). Two hundred forty day-old broiler chicks (Ross, 308) were randomly assigned to one of four dietary treatments with four replicate pens per treatment (15 birds per pen) in a completely randomized design with a 2 × 4 fa...

Twenty wether lambs were individually fed for 84 days to study the effect of dietary lead on performance and mineral composit ion of selected tissues. The treatments included O, 10, 100, 500 and 1,000 ppm supplemental lead as lead acetate added to a practical diet. Increased dietary lead did not affect feed consumption, weight gain or feed conversion ratio. Hemoglobin, hematocri t and blood lea...

The primary aim of this study was to assay the influence of dietary Ca sources and levels on performance, egg quality indices, and selected blood variables of laying hens. A total of 192 Bovanz commercial layers were distributed to 6 dietary treatment groups with 4 replicates and 8 birds in each replicate. The experimental diets were iso-caloric and iso-nitrogenous, but they were different in t...

This experiment was conducted to investigate the effect of dietary supplementation with green tea extract on growth performance, meat quality and oxidative stability longissimus thoracis et lumborum (LTL) muscle in growing-finishing pigs. A total 16 crossbred pigs, half females males, were randomly assigned 2 treatments. lasted 9 weeks included grower finisher periods. The experimental diets ea...
