the study was carried out to investigate the effects of camelia (camelina sativa l. crantz) variety (cs) oil or seeds on performance, meat quality, immunity and plasma metabolic profile in broiler chickens. the broilers (n= 2,080, cobb 500) were randomly allocated (sex ratio 1:1) for 32-day experimental periods (from 11d to 42 d) to 4 experimental groups: control (corn-soybean meal-full fat soy...

Three experiments were conducted to determine the effects of cattle age and dietary forage level on the utilization of corn fed whole or ground to feedlot cattle. In Exp. 1, 16 steers were used to investigate the effects of cattle age and corn processing on diet digestibility. Two cattle age categories were evaluated (weanling [254 +/- 20 kg BW] and yearling [477 +/- 29 kg BW]; eight steers per...

three hundred and sixty male day- old ross 308 broiler chicks were randomly assigned to four dietary treatments in order to evaluate the effect of propolis as growth promoter on the performance and the immune response of the broiler chicks to the nd vaccine. each treatment contained three replicates of 30 chicks. dietary treatments were as follow: a corn - soy meal diet (control diet).control d...

A study was conducted to investigate the response to supplemental tallow of lactating cows fed basal diets with different alfalfa silage:corn silage ratios. We postulated that supplemental tallow will have decreasing negative effects on rumen fermentation, dry matter intake (DMI), and milk fat percentage as the dietary ratio of alfalfa silage:corn silage is increased. Eighteen Holstein cows ave...

this project was conducted to evaluation the effects of replacement of barley grain with corn grain on fatteningperformance of male lambs. twenty five male lambs (6-7 month-old, average body weight = 31.22 ± 3.4 kg) were assigned randomly to five dietary treatments (5 lambs/treatment) in a randomized complete design. the first diet contained barley grain without corn grain but in the other diet...

poultry requirments for vitamins and minerals are met from two sources feed ingredients and premixes.in practical poultry nutrition, the role of feed ingredients is over looked. this experiment was conducted to evaluate the effects of the time of vitamin and mineral premixes withdrawal on growth and economic performance of broilers. four hundred and fifty, one day-old male broiler chickens (ros...

OBJECTIVE This experiment was conducted to determine the effects of dietary β-mannanase on the additivity of true metabolizable energy (TME) and nitrogen-corrected true metabolizable energy (TMEn) for broiler diets. METHODS A total of 144 21-day-old broilers were randomly allotted to 12 dietary treatments with 6 replicates. Five treatments consisted of 5 ingredients of corn, wheat, soybean me...

Distillers grains (DG), a co-product of ethanol production used as protein and energy supplements in cattle diets, have been shown to increase fecal shedding of Escherichia coli O157:H7, a major foodborne pathogen. The reason for the positive association is not known. Because DG often replaces grain in the diet, decreased starch content and flow to the hindgut may create a favorable environment...

and Implications Because treatment with calcium oxide (CaO) will increase the digestibility of corn stover, CaO-treated corn stover may be a cost-effective alternative to a portion of corn grain in beef feedlot diets. Single-pass harvested corn stover was ensiled either untreated or treated with 5% CaO on a dry matter (DM) basis. Ground baled stover, untreated stover silage, or CaO-treated stov...
