In order to determination of ileum apparent and true digestibility of two samples of poultry by product meal, an experiment was conducted with a total of 60 day-old broiler chicks, Ross 308 strain. Poultry by-product meal was prepared from two slaughter house in Alborz province. Samples were sent to laboratory for determination of chemical analysis. The birds received commercial broiler starter...

The Effects of Probiotic and Thyme Powder on Growth Performance, Carcass Traits Blood Biochemical Parameters Broilers with Normal Crude Protein Reduced Diets

use poor quality resources of water and soil for food production in developing countries must be considered. therefore, three experiments were conduct in complete randomize design with four replications, to study effects of gradually application of different salinity levels (0, 10, 20, 30, 40, 50 and 60 ds.m-1) at different growth stages (planting and early seedling) and gradually application s...

the nutritive value of pistachio epicarp (pe) was evaluated by in situ and in vitro techniques. chemical analysis indicated that pe was high in crude protein (11.30%) and low in neutral detergent fiber (26.20%). total phenols, total tannins, condensed tannins and hydrolysable tannins contents in pe were 8.29%, 4.48%, 0.49% and 3.79%, respectively. ruminal dry matter and crude protein degradatio...

Four diets with different crude protein levels 17.75%, 19.95%, 21.85%, 24.08% were used to feed 192 seven-week-old yellow quails in this experiment. During 50-day-old to 95-day-old, laying rate, feed intake and egg weight were recorded to analysis the effect of different levels of dietary protein on the performance of yellow quails. All fences were collected and analysis the effect of different...

the effects of two diets, a control diet (commercial feed with 39% crude protein) and an experimental diet (prepared based on 42% soybean meal with 38% crude protein), on growth performance of western white shrimp (litopenaeus vannamei) in six 0.4-ha-earthen ponds (three replications per treatment) with 25 per m2 density, were investigated. there was no significant difference in final weight (m...

this experiment was conducted to evaluate the effect of spirulina pletensis powder on the growth performances (final weight (fw), daily growth ratio (dgr), feed indices (feed conversion rate (fcr), voluntary feed intake (vfi), protein efficiency ratio (per), protein produce value (ppv), body chemical (protein, fat, moisture and ash) and fatty acid composition of mugil cephalus for 62 days. the ...

background: seaweeds contain significant quantities of lipids, protein, vitamins and minerals. aquavac ergosan contains 1% alginic acid extracted from two brown seaweeds, laminaria digitata and ascophyllum nodosum. both in vivo and in-vitro researches have mainly been focused on the effect of ergosan on fish growth, survival rate, reproductive performance and innate immunity in blood and epider...

Two experiments were conducted to examine the effect of the level of dietary crude protein and protein source on intestinal populations of Clostridium perfringens in broilers. In experiment 1, 6 groups of 12 birds were fed diets containing 230,315 or 400 g/kg crude protein with soy protein concentrate (SPC) or low-temperature-dried fishmeal as the major protein sources in a 2 x 3 factorial arra...

The purpose of this study was to determine the effect fermented straw supplementation with green concentrate on nutrient content and digestibility. Green used as treatment white lead tree leaf flour ( Leucaena leucocephala ), Gamal meal Gliricidia sepium Indigofera meal. Proximate analysis carried out rice straw, 70% + 30% lamtoro (FRS tree), ) ). livestock for digestibility test 12 Friesian Ho...
