Experiments were performed in 110 ISA Brown egg production hens (Gallus gallus), kept from 15 to 26 weeks of age in enriched (furnished) housing technology. The present objective was to investigate the presence of single nucleotide polymorphisms (SNPs) of the ATP2B1 gene and their effects on calcium homeostasis in laying hens. The plasma membrane c...
The precaecal digestibility of phosphorus and calcium in laying hens was evaluated at two dietary levels of non-phytate phosphorus (NPP; 1.58 and 2.03 g/kg) and two levels of exogenous 3-phytase (F; 0 and 300 phytase units (FTU)/kg). A total of 192 ISA Brown hens were used for the study, and were housed in enriched cages (8 per cage). At the end of...
Bone fragility in caged laying hens is a severe welfare problem. This fragility has been attributed to osteoporosis, which etiology is multifactorial in birds, as well as in humans, with genetic, environmental, and nutritional components. Plasma membrane calcium-transporting ATPase 1 gene (ATP2B1) is in hens located on chromosome 1, region 43 273 7...
Coefficients of ileal apparent digestibility (CIAD) for crude protein (CP) and amino acids in five protein feedstuffs: corn distillers dried grains with solubles (DDGS), raw full-fat soybean (RFFSB), extruded full fat soybean (EFFSB), soybean meal (SBM), and rapeseed meal (RSM) were determined using 5-week-old male broiler chickens. Trypsin activit...

An experiment was conducted to determine the effect of different levels of exogenous phytase on egg quality in laying hens fed diets with low levels of only plant original phosphorus. Twenty four Lohmann Brown hens at 31 weeks of age...
This study was conducted to determine apparent ileal amino acids digestibility (AIAAD) of diets with different levels of corn distiller's dried grains with solubles (DDGS) and to determine AIAAD of corn DDGS by difference and regression methods in broiler chickens. One hundred and fifty 30-day-old male broiler chickens were used in the experiment....
The aim of the study was to evaluate the eff ect of the season on incidence of footpad dermatitis and to determine the eff ect of footpad dermatitis on broilers performance expressed by EPEF (European Production Effi ciency Factor). The incidence of footpad dermatitis was evaluated during the year. Daily mortality, weights and feed consumption were...

... For example, in caged laying hens, the fragility of their bones is a serious problem (Steinerova et al., , 2019b(Steinerova et al., , 2020, whereas in commercial flocks, fractures occur in more than 30% of all laying hens during their lifetime. The disease is multifactorial, with environmental, nutritional, and genetic components (Horecka et al., 2015(Horecka et al., , 2018. ...

... In contrast to the previous study in laying hens, the c.31G>A polymorphism was associated with bone strength in the tested broiler hybrids. Horecka et al. [9] dealt with a very similar study in ISA Brown laying hybrids, in the number of 110 individuals, who tried to find polymorphisms in relation to calcium homeostasis in ATP2B1 gene and the same observed bone parameters, whereas no significant effects were found. Jansen et al. [13] identified 16 potential candidate genes, based on their search for SNPs, that were associated with bone mineral density and bone breaking strength. ...
... In a study with piglets, Pallauf et al. (1994) found that a significant improvement (about 10% higher) in Ca utilisation was observed as a result of phytase addition compared with the control group fed no phytase. However, Musilova et al. (2017) found no effect of 300 FTU/kg of exogenous phytase on the daily calcium intake, the amount of absorbed calcium, the content of calcium in ileal digesta, and on the precaecal digestibility of calcium. ...

... The results showed that the apparent digestibility of corn DDGS is beneficial to Silurus Glanis, and 30% DDGS can be added into the Silurus Glanis' diet without affecting the growth performance and nutrient utilization of Silurus Glanis [115]. Determination of the effect of different levels of corn DDGS feed on broiler amino acid digestibility showed that higher levels of DDGS could reduce broiler amino acid digestibility [116]. Some scholars have used a combination of alkaline and enzymatic methods to extract cellulose from corn kernels and DDGS. ...

... Broiler hybrids, which have been subjected to high levels of selection for high productivity and rapid growth, have also become highly sensitive to environmental factors (Beg et al., 2011;Musilová et al., 2013). Therefore, optimizing the indoor conditions in poultry houses is crucial for maximum efficiency (Beg et al., 2011;De Jong et al., 2014;Federici et al., 2016). ...

... Kluth et al. (2005) defined the section of the intestine which needs to be collected. Regarding recent literature, many authors have used this or comparable approaches for estimating protein quality in different feedstuffs for broiler chickens (Short et al., 1999;Kluth and Rodehutscord, 2009;Foltyn et al., 2015;Rada et al., 2017). ...
... The phytase enzyme catalyzes the hydrolysis of phytate and releases a usable form of inorganic P to poultry (Mullaney et al., 2000). It is produced by plants, animals, and microorganisms, and microbial phytase is a commonly used exogenous enzyme in non-ruminant animals (Musilová et al., 2014). The poultry gastrointestinal tract lacks adequate amounts of endogenous phytase to hydrolyze phytate and release bound P (Sebastian et al., 1998), so their diets are usually supplemented with inorganic P. ...
