The aim the study was to evaluate effect dietary diatomite-bentonite mixture (DBM) supplementation on quantitative qualitative composition bacterial microbiome broiler chicken gut. trial carried out 960 Ross 308 chickens divided into 2 experimental groups throughout entire rearing period lasting 6 weeks. birds were fed complete granulated...

Diatomite has recently been the subject of intensive scientific research aimed at its extensive use in industry, breeding and agriculture. The only active diatomite mine is Jawornik Ruski, Podkarpacie region Poland. Chemical pollution environment, including that from heavy metals, poses a threat to living organisms. Reducing mobility metals environment through (DT) gained much interest. More effective immobilisation with DT, mainly modification physical chemical properties by various...

Increased ruminal butyrate production is considered to have a positive impact on rumen epithelium growth and function. However, excessive may affect the negatively, particularly when already challenged with low pH. The aim of this study was determine effect inclusion concentrates in diet sodium (SB) supplementation function growing rams. Forty-two rams (27.8 ± 7.3 kg; 9-14 months age) were allocated into six treatments fed (22.5% DM; LOW) or high (60% HIGH) combination no (SB0), 1.6% (SB1.6)...

The current study investigated the time-dependent effects of maternal exposure to non-toxic ACR doses on oxidative stress, liver function, basal blood morphology rat offspring. Pregnant, Wistar rats were randomly divided into control group or groups administrated with (3 mg/kg b.w./day): long for 15 days, medium 10 days short 5 during pregnancy. Body mass, hematology, serum concentrations...

Abstract The negative effect of caponization on the structural, geometric and mechanical parameters femur tibia has been shown in a few studies. Nevertheless, its influence bone microarchitecture is still largely unknown. Therefore, this study aimed to assess castration microstructural trabecular compact crossbred chickens. experiment involved 96 roosters derived from crossing Yellowleg Partridge hens ( $${\dot{\text{Z}}}$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML">...

Changes in the structure and properties of intramuscular connective tissue, muscle fibre size, collagen content meat tenderness m. longissimus lumborum during growth was studied 45 Polish Large White (PLW) pigs slaughtered at 90, 150 210 days age. The results show that endomysial sheath consists fibrils wavy appearance which run all directions form a loose network. arrangement endomysium perimysium becomes denser more regular with increasing age pigs. In addition, increase thickness...

Abstract The aim of this study was to evaluate the effect feed restriction on carcass composition, breast meat quality and microstructure m. pectoralis superficialis broiler chickens. A total 315 day-old female broilers (Ross 308) were randomly assigned 3 groups 105 birds each in pen replicates. They fed ad libitum as control (I), restricted for 6 h/day (from 08:00 14:00 h) group II (3 4 weeks age) III from 5 age. On day 42 growth, with average body weight chosen slaughter analyse dressing...

The quality of chicken meat, which is one the most widely consumed meats in world, has been subject research and studies for many years. There are several ways to improve this type including changing concentrations individual molecular components. Such important components meat inter alia, cholesterol, vitamin E, some fatty acids such as ω-3 ω-6. Manipulation ingredient levels may be achieved by enriching feed with elements different types vegetable oils, garlic, or selenium. Thus far,...

Pulmonary arterial hypertension (PAH) is a rare, fatal, and incurable disorder. Although advances in the understanding of PAH pathobiology have been seen recent years, molecular processes underlying heart remodelling over course are still insufficiently understood. Therefore, aim this study was to investigate myocardial proteomic profile rats at different stages monocrotaline-induced PAH. Samples left right ventricle (LV RV) free wall collected from 32 Wistar were subjected analysis using an...

Carcass, meat quality and muscle fibre traits of m. longissimus lumborum were studied in 61 Zlotnicka Spotted (ZS) pigs 35 commercial crossbred (Polish Large White x Polish Landrace) pigs. The animals received organic feed ad libitum slaughtered at 210 days age. current findings indicate that both slaughter weight cold carcass significantly lower, backfat thickness higher for ZS compared to pigs, while the exhibited longer carcasses greater area, height width loin eye. No significant...

Abstract Background Intensive selection for growth rate (GR) in broiler chickens carries negative after-effects, such as aberrations skeletal development and the immune system, heart failure, deterioration of meat quality. In Poland, fast-growing chicken populations are highly non-uniform term rate, which is unprofitable poultry producers. Therefore, identification genetic markers boiler GR that could support process needed. The hypothalamus strongly associated with regulation by inducing...
