The objective of this study was to evaluate the performance of male broiler chickens in the period from 21 to 42 days of age fed diets with increasing levels of sunflower meal (SM) supplemented with an enzyme complex (EC). A total of 1920 animals of the Cobb strain were distributed in a randomized block design in a 4 × 3 factorial arrangement (four SM levels and three enzymes utilization types)...

the objective of this study was to investigate the effects of three levels of threonine (100, 95 and 90% of nrc requirements) with or without of multi strains probiotic (primalac) on performance, carcass characteristics and blood metabolites of japanese quails. a total of 180 one-day-old male japanese quails were randomly allocated to six treatments with three replicates and 10 birds per each. ...

320 one-day male broilers (ross 308) were divided in 4 treatments (with 4 replicate and 20 chicks for a replicate). all of broilers reared under a cold environmental temperature to induce ascites .experimental treatments were included 1: was fed a commercial corn-soybean meal- based diet meeting nrc (1994) including 1.2% arg and 40 iu of vitamin e/kg (control), 2: control with 400 iu of vitamin...

in order to investigate the effect of partial replacement of barley starch with beet pulp soluble fiber with or without roasted canola seed on apparent nutrient digestibility, dry matter intake, daily weight gain, feed conversion ratio and rumenal ph 24 arabian male lambs were used for 84 days in a completely randomized design with a 2×2 factorial arrangement. treatments had no significant effe...

this study was investigate the effects of two levels of metabolism energy (me) and length of fattening periods on performance and growth characteristics of chalishtori male lambs. 64 ram lambs were weaning and intake diets with two levels of energy include: 2.5 and 2.3 mcal me/kg dm in 90 and 120 days fattening period. in this study used of completely random designs with 2×2 factorial methods (...

effect of intermittent mash-pellet feeding programs on broilers performance, ascites susceptibility and economic yield was studied using 480 broilers in six treatments and five replicates of 16 chicks per pen were used in a completely randomized design. treatments including: 1. mash feed, 2. heated-mash feed, 3. mash feed in starter and grower and pellet feed in finisher, 4. mash feed in starte...

This research project was conducted to evaluate bioavailability and chemical properties of different zinc sources in broiler chickens when fed by practical diets. For that, 312 day-old male Ross 308 broiler chicks were fed from 8-28 day to estimate the biological availability of four zinc sources. Chicks were allocated randomly to 13 experimental diets in a 3 × 4 factorial design. Diets include...

effect of adding melissa officinalis aqueous extract was studied on immune response and performance in 200 ross 308 broiler chicks in a completely randomized design with five treatments and four replicates and 10 observations per replicate. the amounts of 0 (control), 0.5, 1, 1.5 and 2 ml/l lemon balm extract were added in drinking water for 42 days. humoral immunity was evaluated by injection ...

six hundred 1-d-old male broilers (ross 308) were assigned to four experimental groups; each was composed of 5 floor pen replications of 30 birds including control (no enalapril), 15, 30 and 60 ppm enalapril in the drinking water. from d 21 to 49, all the chicks were exposed to low ambient temperature to induce ascites. mortalities were inspected to determine the cause of death and diagnose of ...
