The objective of this study was to investigate the effects of feeding electron irradiated flaxseed (FS) on performance, carcass characteristics, blood parameters, digesta viscosity, and nutrient digestibility in broiler chickens. In a 2 × 2 factorial arrangement, 320 day-old broiler chicks were randomly assigned to one of five experimental diets, each with four replicates containing 16 chicks e...

the interaction between sodium and calcium, magnesium and calcium and the combined effect of sodium, magnesium and calcium was observed on the growth and ion uptake of hippophae rhamnoides l. the results demonstrated that an addition of sodium with calcium, (set a, na 2.5 + ca 5 mm) showed prominent increase in fresh weight of roots and shoots. the dry weight (average) of roots decreased and th...

this research which aims to survey the relation between tobacco leaf yield and its components is done by using 118 varieties of tobacco in a research farm of guilan tobacco research institute. regarding to five random selections of plants, twenty three traits of each variety were evaluated. correlation between dry matter of leaf yield with plant height, stem diameter, leaf length, leaf width, l...

in order to examine the effect of using rumen protected methionine (mepron, evonik industries, hanau, germany) on productive and reproductive performance under field condition, 195 holstein cows were used in a unbalanced completely randomized design and 2 groups. experimental treatments consisted of: 1) control group with 110 holstein dairy cows (71±51 dim and 47.5±12 milk yield) and without me...

in this study, the chemical composition of the tea wastes determined. the value of dry matter, organic matter, crude protein, crude fiber, calcium and phosphorous 95, 94, 13.3, 23.1, 0.011 and 0.29 percent, respectively. in the experiment of digestibility by animal, five experimental rations (including tea waste and alfalfa in the proportion of 0:100, 10:90, 20:80, 25:75 and 30:70 percent) and ...

The development of the yield and nutritive value of timothy (Phleum pratense L.) both in the primary growth and in the regrowth were studied at MTT Plant Production Research, a unit of MTT Agrifood Research Finland, in Rovaniemi (66°35 ́N) in 1999–2001. The dry matter yield and leaf to stem ratio were measured from the crop samples, and the contents of crude protein and organic matter digestibil...

The objectives of this study were to expand the database and determine the intestinal digestibility of rumen undegradable protein (dRUP) of common dairy feeds and to determine the effects of feeding 37.9% wet corn gluten feed on these estimates. Two ruminally and duodenally fistulated steers were assigned randomly to a crossover design with 4-wk periods. The mobile bag technique was used to det...

The effect of ephedrine at 0 (E0C0, n = 10), 8 (E8C0, n = 10) and 10 (E10C0, n = 10) mg per kg metabolic body weight or mixture of ephedrine/caffeine, at doses of 8 mg ephedrine/80 mg caffeine (E8C80, n = 10), or 10 mg ephedrine/100 mg caffeine (E10C100, n = 7), per kg metabolic body weight on body composition of feedlot Mehraban ram lambs (8-month-old) was studied. The lambs were fed for 95 da...

To assessment effect of concentration and times of disinfection wheat seeds, infected by Aspergillus fungus a research was conducted based on Factorial experiment according randomized complete block design with four replications. The factors included four levels of sodium hypochlorite (2, 4, 6, and 8%) and four times of seed disinfection (2, 5, 7, and 10 minutes). Result of analysis of variance...
