this experiment was carried out to study the effects of different levels of canola meal of different fat sources on the egg quality, performance as well egg yolk cholesterol during the first 12 weeks of age in laying hens (hy-line w-36). throughout the experiment a total of 432 hens were employed in a completely randomized design in a factorial arrangement of 3×4, with three levels of canola me...

this experiment was conducted using 172 male lambs of ghezel and mehraban breeds for two periods of 60 and 80 days. two systems of fattening were studied. the first group of lambs entered feedlot boxes immediately after weaning (spring) but the second group being fed on pasture, entered the experiment approximately 4 months later (autumn). fattening periods were 60 and 80 days. the average wean...

Aim The purpose of this study was to know the production performance and economic analysis in quail which use probiotic supplementation to alternate antibiotic growth promoter (AGP) to feed consumption, water consumption, egg production, egg mass, feed conversion, and feed efficiency. Materials and Methods About 240 quails (Coturnix coturnix japonica) at 14 weeks of age were completely random...

The amount of feed consumed per day and the rate of food passage was measured in mink and European ferrets. Daily feed consumption averaged 40 and 42 g dry matter per kg body weight for male mink and ferrets and 53 and 49 g dry matter per kg body weight for female mink and ferrets, respectively. Using ferric oxide as a feed marker, no differences were observed in food passage time between mink ...

an experiment was conducted to evaluate the effect of dietary crude protein and methionine levels on quality and quantity of egg production. fifteen diets formulated with 3 levels of protein (13, 14 and 15%) and 5 levels of methionine (0.25, 0.28, 0.31, 0.34 and 0.37%) and fed to 420 birds in a 3×5 factorial arrangement. each diet was randomly fed to 4 replicates of 7 birds each and fed for 3 p...

BACKGROUND AND AIM In today era, broiler industry facing a problem of price hiking of feed of broiler, also in competitive era there should be lower feed cost, lower feed conversion ratio, low feed consumption yet good body weight at marketable age. MATERIALS AND METHODS Day-old commercial broiler chicks (n=200) were distributed randomly into 5 dietary treatment groups viz. control (T1), prob...

Contamination of animal and poultry feeds by Fusarium and the mycotoxin Fumonisin B1 is frequent in the feed supply chain. The present study evaluated the prevalence of fumonisin B1 producing Fusarium among irradiated and non-irradiated animal and poultry feed mixtures. Further, the efficiency of γ-rays (2.5, 5.0, 7.5, and 10.0 kGy) to minimize Fusarium growth and biosynthesis of fumonisin B1 i...

Two CHO cell clones derived from the same parental CHOBC® cell line and producing the same monoclonal antibody (BC-G, a low producing clone; BC-P, a high producing clone) were tested in four basal media in all possible combinations with three feeds (=12 conditions) in fed-batch cultures. Higher amino acid feeding did not always lead to higher mAb production. The two clones showed differences in...

Preference tests and meal pattern analyses were conducted to examine the feed intake response of weanling pigs to spray-dried porcine plasma (SDPP). In Exp. 1, 36 weanling pigs (mean +/- SD; 6.2 +/- .8 kg and 26 d of age) were allowed to choose between a SDPP diet (8.5% SDPP, 20% dried whey, 10% lactose, and .13% DL-methionine) and a dried skim milk (DSM) diet (20% each of DSM and dried whey) t...

________________________________________________________________________________ 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...
