the experiment was to study the effects of replacing soybean meal by rubber seed meal on growth, economics and carcass characteristics of broiler. a total of 150 day-old commercial broiler (cobb-500) was reared for a period of 35 days. there were five treatments including t0 (without rubber seed meal), t1 (10% rubber seed meal), t2 (20% rubber seed meal), and t3 (30% rubber seed meal) and t4 (4...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
An experiment was conducted to evaluate the effects of wheat and wheat bran diets with and without enzymes on growth performance and digestive characteristics of broilers. A total number of 625 one day old Ross-308 broiler chickens were allocated randomly to 5 treatments with 5 replicates, using a CRD statistical design. Treatments were control, wheat, wheat+ enzyme and wheat bran and wheat bra...
This experiment had been done to evaluate the effects of different levels of essential oils (EOs) of wormwood (Artemisia absinthium) and cumin (Cuminum cyminum)on growth performance, carcass characteristics and immune system in broiler chicks. Three hundred ninety two Ross 308 male broiler chicks in a completely randomized design were divided into 7 experimental treatments. The experimental tre...
This study was conducted to investigate the effect of canola seed (raw and roasted) and diet concentrate levels on growth performance and quantitative and qualitative characteristics of carcass of Lori male lambs. A total of 54 male 30±0.86kg lambs were selected for the experiment. Treatments consisted of two levels of canola seed (raw and roasted) and three levels of concentrate (60, 70 and 80...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
to investigate the effect of cinnamon, turmeric and carnation powders on growth performance, carcass characteristics, morphological and ph changes of intestine and blood serum oxidation status in broilers, 450 unsexed ross 308 day-old broiler chicks were randomly allotted in a completely randomized design with six treatments, five replicates and 15 birds per each replicate, for 42 days. the bro...

The inclusion of high concentrations of DDGS (30%) in both the nursery and growing-finishing periods may result in negative effects on growth performance and carcass characteristics. Summary The objective of this experiment was to evaluate the efiects of high concentrations of distillers dried grains with solubles (DDGS; 30%) on growth performance and carcass characteristics ofgilts, duringgrow...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
