An influence of various humic-plant feed additives based on some herbs (nettle, chamomile, yarrow, perforatum), lucerne and humic materials on biochemical indices of Lohmann Brown (LB) layers blood plasma was estimated. Hens were housed in deep litter system, 20 birds in a group. Four groups were formed: control (C - standard feeding), and experimental, supplemented with prepara- tions: E-1 her...

The deposition of dietary folic acid (FA) into the chicken egg is likely regulated by its conversion to 5-methyltetrahydrofolate (5-MTHF), the predominant form of this vitamin in eggs (>80%). Supplementation of 5-MTHF in the laying hens′ diet may therefore enhance total egg folate concentrations. To this end, a study was conducted using equimolar concentration of either FA or 5-MTHF in diets fe...

OBJECTIVE The objective of this experiment was to investigate the effect of dietary β-mannanase on productive performance, egg quality, and utilization of dietary energy and nutrients in aged laying hens raised under hot climatic conditions. METHODS A total of 320 84-wk-old Hy-line Brown aged laying hens were allotted to one of four treatments with eight replicates in a completely randomized ...

The effect of the inclusion of meat and bone meal (MBM) in the diet of old laying hens on their egg production and the quality of their eggs was investigated. Meat and bone meal containing a high concentration of ash and a low concentration of crude protein was included at levels of 2.0, 4.0 and 6.0% in the diets and fed for 20 weeks. Forced moulted 84-week old laying hens (Brown-Nick) were div...

This study aimed to investigate the effect of tetramethylpyrazine (TMP) supplementation on egg production, nutrient retention and cecal microbiota diversity using 288 commercial Hy-Line brown hens as wk 75 86. Four treatments consisted TMP addition at 0 (control, basal diet), 100, 150 200 mg/kg diet. The results showed that diets supplemented with improved egg-laying rate 77 compared control, w...

On the market of feed and veterinary additives, there is a wide range drugs that have positive effect on poultry body. We conducted scientific economic experiment to study probiotic based Bacillus subtilis productivity laying hens Brown Nick cross. Each enterprise strives find most optimal solutions for its production. Thus, we experiment. For experiment, two groups were selected - layers cross...

Seventy Brown-Nick laying hens (39-wk old) were divided into 5 treatment groups of similar mean body weight and egg production, comprising 14 birds in each. The housed individual cages a completely randomized design 16:8 h light:dark photoperiod was employed. fed standard layer diets containing different levels lutein for 6 weeks. Treatment included control (without lutein), 100, 200, 400 800 p...

Loss of shell colour in brown-egg layers is a shell quality issue in Australia and is periodically associated with free range egg production. This study investigated the loss of shell colour that occurs in some flocks of free range laying hens. Hens laying pale-coloured egg shells on a commercial free range farm were transferred to cages in an experimental facility. Egg quality was measured imm...

<p class="MDPI17abstract"><strong>Objective: </strong>Lactic acid bacteria are known to improve performance and gut health of laying hens. Several potential microbiotas that could enhance <em>Lactobacillus acidophilus, Lactobacillus bulgaricus, Streptococcus thermophilus, </em>and <em>Bifidobacterium sp.</em> Probiotics microorganisms play a role in imp...
