In this study, organically raised pigs received an increasing proportion of grass silage up to 10 and 20% dry matter in the daily ration in the grower and finisher period, respectively, to determine the effects of grass silage on feed intake and growth performance. The pigs receiving a mixture of grass silage and compound feed ingested 0.3 kg DM/d (13% of their daily ration) as grass silage and...

To study the effects of α-galactosidase (α-Gal) supplementation on performance and energy metabolism, 216 Arbor Acres male broilers were placed in 36 cages of 6 birds each and allotted to 4 diets for 42 d, with 0-21 d as starter period and 22-42 d as grower period. The 4 diets were based on corn non-dehulled soybean meal in a 2×2 factorial arrangement, with 2 levels of α-Gal (0 vs. 60 U/kg feed...

this experiment was carried out to evaluate the effect of different levels guar meal and β-mannanase on broilers male chicken. in this experiment , four hundred ross day old broiler chicks were randomly assigned to a 4×2 factorial design to feed broiler chickens diets containing guar meal at 4 level of guar meal (0, 3, 6 and 9%) with five replications of each treatment with or without β-mannana...

Data from a 3-yr feeding trial of crossbred steers (n = 331) were used to examine the relationship between feeding behavior traits and feed efficiency in steers fed grower and finisher diets, successively. There were 2 feeding periods each year whereby the steers were fed a grower diet in the first feeding period (P1) and a finisher diet in the second feeding period (P2). Each feeding period la...

The effect of a Buttiauxella phytase, in a dose range of 0-1000 FTU/kg in feed, on production performance in growing/finishing pigs fed European type wheat, corn, barley and SBM based diet was determined. Five dietary treatments were tested including a positive control (PC), a negative control (NC) without inorganic P and with reduced Ca (–0.12%) and metabolisable energy content (–0.14 MJ ME/kg...

The aim of the present study was to examine the influence of raw seeds of grass pea (Lathyrus sativus L.) in feed mixtures for grower-finisher pigs on growth performance, and biochemical and haematological parameters in their blood, as well as on the weight of the liver and the kidney. The experiment was performed on 96 grower-finisher pigs of (Polish Landrace × Polish Large White) × Pietrain, ...

This study evaluated the effect of 2 levels (0 vs. 8%) of distillers dried grains with solubles (DDGS) in a starter broiler diet (0 to 14 d; 45 replicates/treatment) after these same birds were subsequently fed a grower diet (14 to 28 d) with either 0, 7.5, 15, 22.5, or 30% DDGS (9 replicates/treatment). Ross×Ross 308 male broilers were used in this experiment, and evaluation criteria consisted...

the aim of this study was to compare the effects of three antibiotic alternatives with a control (antibiotic-free) and an antibiotic diet on performance and gut morphology of broilers reared on litter. 600 day-old ross-308 chicks were assigned to 48 pens in a crd design with 6 × 2 factorial arrangements, in which 2 levels of chick density (5 and 7.5 chicks/m2) and 6 experimental diets (control,...
