BACKGROUND This study examined the effects of dietary supplementation with rice bran, sire breed and gender on live animal performance and carcass characteristics in Australian crossbred and purebred Merino lambs. METHODS Forty-eight lambs balanced by sire breed (Dorset, White Suffolk, Merino) and gender (ewe, wether) were randomly allocated into three dietary supplementation groups (Control-...

objective: citrinin is a mycotoxin produced by several species of the genera aspergillus and penicillium and occurs mainly in food products and animal feed. some scientific reports show a link between citrinin and nephrotoxic and possibly a carcinogenic effect for humans. methods: samples collected by settling plates,in northern iran and pure culture isolation performed till the toxin measureme...

Current industry practices for large-scale mammalian cell cultures typically employ a standard platform fed-batch process with fixed volume bolus feeding. Although widely used, these processes are unable to respond to actual nutrient consumption demands from the culture, which can result in accumulation of by-products and depletion of certain nutrients. This work demonstrates the application of...

This study was conducted to evaluate the effect of fasting period with or without enzyme supplementation on body weight, body weight gain, feed intake, and feed conversion ratio; carcass traits and blood parameters of broilers. One hundred sixty eight, one day old, Cobb broiler chicks were randomly distributed into eight treatments. Each treatment included three replicates each with 7 birds. Bi...

________________________________________________________________________________ Abstract The effect of sex and the supplementation of the prebiotic, mannan oligosaccharides (MOS), the acidifier, calcium propionate (CPr) or their combination in the feed of Japanese quail (Coturnix japonica) on their performance and carcass quality was examined in this experimentation. Three hundred, 1-day old J...

This study was carried out to investigate the effect of different body weight groups (light (L) = 1 400–1 500; medium (M) = 1 500–1 600 and heavy (H) = 1 600 < g) on performance and egg quality traits of Lohmann hens, 24 weeks of age, in different laying periods. A total of 288 Lohmann White layers were allocated randomly to three groups with respect to live weight, each consisting of 24 replic...

in this study, the effects of culban seed (vicia peregrine l.) on live body weight, feed intake, feed efficiency, egg production, egg quality characteristics, egg yolk fatty acid profiles and yolk cholesterol content in laying hens were investigated. the experiment consists of seven treatment groups with ten replications containing one laying hen in each and for 32 weeks old seventy laying hen ...

High environmental temperatures have deleterious effects, reducing the feed intake, live weight gain and feed efficiency of poultry. A study utilizing Ross 308 was conducted to evaluate the effects of vitamin C (Ascorbic acid) and glucose on broilers production reared under heat stress (32 ± 2 °C). One day-old, five hundred twenty five broilers were randomly assigned to 7 treatment groups with ...

Total sixty four straight run broiler chicks of two daysold were fed a control diet and diet supplemented with Fungi inhibitor (FI): Gentian violet (GV), Copper sulphate (CS), GV+CSto evaluate the effect of dietary FI on the performance characteristics of broiler. The levels of GV, CS and GV+CS were 0.05%, 0.06% and 0.025%+0.06%, respectively. Dietary FI did not alter the growth rate, feed inta...

Laying hens were fed for a 48-wk period with a basal diet supplemented with a selected strain of Lactobacillus acidophilus at levels up to four million viable cells per gram of feed. Levels of egg production and feed conversion were significantly higher (8 and 14.8%, respectively) than in the control flock, and cholesterol values in yolks were decreased by 18.8%. It is suggested that the latter...
