In recent years, there has been an increasing interest in using food additives from natural sources to improve taste and also extend the shelf-life of semi-preserved foodstuffs. The aim of this study was to examine the chemical and microbiological changes promoted by a local marinating process in rainbow trout fillets during chilled storage. Fish fillets were immersed in marinades and stored at...

An experiment was conducted to examine the effect that various isoenergetic diets, containing different quantities of soluble carbohydrate and fiber and different types of starch, have on nitrogen (N) balances. Six lactating dairy cows in early to midlactation consuming grass silage diets with not less than 600 g/kg total DMI as forage were used in the experiment. Four concentrates were prepare...

An experiment was conducted to evaluate the effect of different levels of germinated barley (GB) on live performance and carcass traits in broiler chickens. The experiment lasted for 5 weeks starting from 7 days of age and ending at 42 days of age. Chicks (Ross 308) were fed six dietary treatments including a corn–soy diet (corn diet), a barley–soy diet (barley diet), a barley diet plus enzymes...

thirty two multiparous holstein cows were used in a randomized block design to investigate the effects of feeding diets included two different source of nonfiber carbohydrate during the transition period on dry matter intake (dmi), lactational performance, blood metabolites and parturitional characteristics. cows received total mixed rations containing either macaroni wastes(mw) or steam-flaked...

Effects of soluble and insoluble fiber preparations isolated from defatted oat, barley, and wheat on liver cholesterol accumulation were examined in cholesterol-fed rats. The soluble and insoluble fiber preparations were isolated by a modification of the procedure of Asp et al. Male Sprague-Dawley rats, aged 5 weeks, were fed a control diet containing 5% cellulose or diets containing soluble an...

The study was conducted to investigate the effects of graded dietary inclusion levels of betaine on ileal and total tract nutrient digestibilities and intestinal bacterial metabolites in piglets. A total of eight barrows with an average initial body weight of 7.9 kg were randomly allocated to one of the four assay diets with two pigs per treatment in four repeated measurement periods. The assay...

the aim of the present study was to determine the effects of different levels of lysine amino acid on immunity and some blood biochemical parameters of broiler breeder hens. the treatments were consisted of 6 levels of lysine (0.50, 0.57, 0.64, 0.71, 0.78 and 0.85%) and were used in a completely randomized design with 4 replicates and 8 hens in each pen from 52 to 64 weeks of their rearing peri...
