One experiment was conducted using 960 1-d-old, sexed broilers of Ross 308 strain from 1 to 43 d evaluate if one type chemically isomerized marigold with 25% xanthophylls as zeaxanthin (SME-25) could produce pigmentation equivalent the current addition conventional 10% (SME-10) plus canthaxanthin (CTX) in practical broiler diets (maize-wheat-soybean). Birds were allocated 32 pens, a randomized complete block design (four blocks × four treatments). The treatments consisted nonpigmented...

The effects of microbial 3-phytase and glycosidase enzymes, their interactions, on energy values nutrient digestibility in diets rich nonstarch polysaccharides (NSP) were studied based corn, wheat, or barley. Four prepared with each cereal grain. One had no a second 500 units phytase, third enzyme, fourth phytase glycosidase. glycosidases used alpha-galactosidase (corn diet), xylanase (wheat), beta-glucanase (barley). Glycosidase decreased intestinal viscosity, whereas increased this...

The objectives of this study were to investigate the effects dietary fat (6% lard and sunflower olive oil) supplementation α-tocopheryl acetate or β-carotene on vitamin E content lipid oxidation in raw, cooked, chilled-stored broiler leg meat. Vitamin increased its tissue level, reducing oxidation. oxidative stability meat tended decrease with oil. Effects levels depended concentration feed, decreasing E, mainly at 50 ppm. β-Carotene 15 ppm acted as antioxidant fresh cooked oil diets....

The objective of the study was to determine effects two enzyme preparations containing beta-glucanase and xylanase activities on barley- wheat-based diets, respectively, for broilers, in combination with flavomycin. In addition, stability after pelleting measured. Temperatures recorded during process reached 75 80 C, recovered respect amounts present mash feed before were 80% or higher. Two performance experiments conducted simultaneously under same conditions over 6 wk. intestinal viscosity...

The present study with 1-day-old male broilers (Ross 308) was conducted to evaluate the effects of deoxynivalenol (DON) at different levels (5 and 15 mg/kg feed) on growth performance, relative weight organs, morphology small intestine, serum biochemistry, welfare parameters broiler chickens. Forty-five chicks were randomly divided into three experimental groups five replicates each: (1) control group received a non-contaminated diet, (2) contaminated diet 5 mg DON/kg feed, (3) feed for 42...

ABSTRACT To determine whether patterns of grain filling were consistent between seasons and different sites in northern southern Europe, the cultivar Troubadour TR49, a mutant derived from it, grown, over two seasons, at Scotland Spain. Differences sowing date climate reflected filling. Ear emergence Scottish grown barley occurred around time when daylight hours maximal; optimal photosynthesis was likely explanation for rapid increase size observed site. temperature rainfall most evident...

Water uptake into the grain is a critical aspect off malting quality. Contrasting environments have been used to examine role of protein and cell wall components in water uptake. A model based on threshold value for content, ratio B C hordeins composition solubility β-glucans has formulated. Better performance associated with lower levels insoluble higher C-Hordein.

Abstract 1. The effect of pelleting process and Trichoderma viride enzymes (TVE) addition on apparent metabolisable energy, corrected for nitrogen balance (AMEn) productive value practical diets containing 40 45% three different barley cultivars one wheat were studied in poultry. 2. the AMEn was inconsistent dependent cereal included enzyme. 3. growth trial showed a significant enzyme to pelleted over whole period (0 42 d). Addition TVE improved weight gain food efficiency by 1.3% 2.9%,...

Abstract Exogenous enzyme supplementation of animal feeds has been practised successfully since the late 1980s. Early research demonstrated that enzymes improve nutritional value several main ingredients such as barley, wheat, rye and triticale. More recent studies have associated feed with environmental welfare benefits. By 2000, around 60 products had authorised in European Union (EU) additives, currently 40 these attained definitive EU approval. This paper reviews legislation relating to...

The current study was conducted to examine the effects of deoxynivalenol (DON) at different levels (5 and 15 mg/kg feed) on metabolism, immune response welfare parameters male broiler chickens (Ross 308) 42 days old. Forty-five 1 day-old were randomly distributed into three dietary treatments: (1) control, (2) DON-contaminated diet with 5 mg DON/kg feed (guidance level), (3) feed. Five replicated cages birds each used for treatment in a randomized complete block design. results showed that...

1. An experiment was carried out to determine the effect of removal supplemental iron and copper from broiler diets during last 3 weeks before slaughter on performance, tissue vitamin E concentrations oxidation values in raw; cooked stored leg meat. 2. Removal diet slightly decreased food efficiency; differences were significant only when both minerals removed simultaneously 3. Effect withdrawal concentration low. However, total reduced animals deprived or simultaneously. 4. dietary did not...

Scope The effects on the enteroendocrine system of three different grape seed proanthocyanidin extract (GSPE) treatments are analyzed in rats a cafeteria diet for 17 weeks. Methods and results GSPE is administered corrective manner (15 last days diet) at two doses, 100 500 mg per kg bw. A third, longer treatment which (500 –1 bw) daily every other week during weeks also tested. Most lead to ghrelin accumulation stomach, limited CCK secretion duodenum, increased GLP‐1 PYY mRNA colon....

The present study was conducted to evaluate the efficacy of feed additive, a novel multicomponent mycotoxin detoxifying agent (MMDA) containing modified zeolite (clinoptilolite), Bacillus subtilis, B. licheniformis, Saccharomyces cerevisiae cell walls, and silymarin, as detoxifiers 0.5 mg/kg (0.5 ppm) ochratoxin A (OTA) 1 (1 T-2 toxin on broiler chickens. total 240 1-old chickens (Ross 308) were randomly distributed into five different dietary treatments: (1) control (non-contaminated diet);...
