A 42-d trial was conducted to study the influence of exogenous alpha-amylase on digestive and performance traits in broilers fed a corn-soybean meal diet. There were two treatments (control supplemented diet) six replicates (14 Cobb male chicks caged together) per treatment. At 7 d age, supplementation improved daily gain by 9.4% (P < or = 0.05) feed conversion 4.2% 0.01). end trial, birds alpha-amylase-supplemented diet ate more grew faster hadbetter 0.10) than control Also, apparent fecal...

Pens (eight pigs/pen) assigned randomly one six treatments arranged in 2 3 factorial design two genders (barrows or gilts) three SW (116, 124, 133 kg). Each treatment was replicated four times. Over entire trial, barrows had higher (P < 0.001) ADFI...

Poultry meat is the major source of human campylobacteriosis, most frequently reported zoonosis in EU. The prevalence Campylobacter colonization European broiler flocks 71%. Despite considerable efforts, there still no effective strategy available to prevent or reduce broilers. This study tested a wide variety feed additives shedding primary poultry production. Twelve containing organic fatty acids, monoglycerides, plant extracts, prebiotics, probiotics were tested. For each additive,...

Abstract Two hundred and forty pigs of 56 ± 3 days age were used to investigate the effects sex (barrows; gilts), boar sire (DD, Danish Duroc; ND × LW, Dutch Duroc Large White ; P Pietrain White) slaughter (160; 175 days) on performance carcass meat quality. Treatments arranged factorially (2 2) there four replicates (five per replicate) treatment. The female line was Landrace in all cases. Barrows had greater daily food intake ( &lt;0·001) average gain &lt;0·01) poorer conversion ratio than...

Crossbred pigs (n = 240) from Pietrain x Large White sires mated to Landrace dams, with an average age of 100 d (60.5 +/- 2.3 kg BW), were used investigate the effects sex and slaughter weight (SW) on growth performance carcass meat quality characteristics. There 6 treatments arranged factorially, 3 classes (intact females, IF; castrated CF; males, CM) 2 weights (114 122 BW). Each combinations was replicated 4 times, experimental unit a pen 10 pigs. Castrated males CF ate more feed, grew...

A total of 636 day-of-hatch Ross 308 broilers chicks were used in 4 independent trials carried out to screen the effect 12 feed additives on reducing cecal colonization Campylobacterin broilers. The tested probiotics based B. subtilis and S. cerevisae, a garlic extract, blend herbal substances essential oils, two different combinations oils organic acids (OA), mixtures flavoring compounds, medium chain fatty (MCFA), monoglycerides (MG) MCFA MG-MCFA+OA. At 14 days age, all birds orally...

A trial was conducted to study the influence of feeding regimen [ad libitum, (AL) vs. feed restriction, (FR)] and supplementation diet with a combination xylanase β-glucanase on physiological parameters performance broilers fed rye-based diets. There were 4 dietary treatments arranged factorially 2 regimens (0 30% FR from 14 d), enzyme doses 500 ppm), an additional corn control diet. Each treatment replicated 9 times 25 d (15 chicks caged together) 6 46 d. From age, did not affect weight...
