The aim of the research was to use a vision technique to assess the relations between anatomical pork carcass traits, carcass geometry and slaughter value. The measurements in the experiment were performed on 128 selected pork carcasses. The 3D image of the carcass was assessed, especially its shape. Based on the carcass curvatures the correlation coefficients for these surfaces and slaughter value traits were calculated. The possibility of using the external dimensions and geometry of pork carcass for the accurate estimation of meatiness and the share of primal cuts using the technique of acquiring carcass images in a 3D configuration was confirmed....

Some herbs can be used as phytogenic additives as they naturally contain specific bioactive phytochemicals that are effective in controlling coccidiosis and some other poultry diseases due to their immunostimulatory effects and they can be also nutritious. The aim of the study was to evaluate the effect of Artemisia absinthium (WW) meal inclusion to a diet on the production performance, oocyst output and minerals content of meat in broilers infested by Eimeria oocysts. Ross 308 broilers were randomly assigned to four dietary groups. Broilers in the control group were fed basal diets without coccidiostat or WW. Broilers of the R...

The aim of the study was to prepare and test the effect of diets with 50% and 100% replacement of soybean meal with dehulled seeds of white lupin (Lupinus albus) variety Zulika. One hundred and eighty Cherry Valley duckling were divided to control group (C) and two experimental groups E50 (50% replacement of soybean meal with dehulled white lupin meal) and E100 (100% replacement of soybean meal with dehulled white lupin meal). There were evaluated the production parameters and the amino acid spectrum of breast and thigh muscles up to 42 days of age. The effect of diets containing lupin meal had no negative effect...

The aim of this study was to evaluate the influence of laying hybrid lines of domestic fowl (Gallus gallus f. domestica) and their age on ejaculate parameters in roosters. Parameters assessed included ejaculate volume, sperm concentration, total sperm count (TSC), percentage of normal spermatozoa, and sperm motility. Additionally, morphological defects were observed: defects of the acrosome, head, neck, tail, and immature spermatozoa. The study included 120 roosters of the Barred Plymouth Rock, Sussex Light, Rhode Island Red, and Rhode Island White laying lines. Ejaculate was repeatedly evaluated at the ages of 34, 43, and 52 weeks. The...
