The aim of this study was to determine the effect of caponization on selected morphometric parameters and mineral density of tibiotarsal bones in Green-legged Partridge cockerels. The experiment was conducted on 200 cockerels. At 8 wks of age, 100 birds were surgically castrated. At 12 and 24 wks of age, blood samples were collected from 10 intact cockerels and 10 capons, and the birds were slaughtered...
The aim of this study was to determine the influence of bio-alginates on the growth rate of pheasant chicks. Two experiments were performed in pheasant chicks were administered the Biopolym supplement from 1 to 29 days of age (experiment 1) or from 1 to 36 days of age (experiment 2).The Biopolym supplement had a significant effect on the growth rate of pheasant chicks, the highestrelative increase...
In the 20th century, members of the family Cervidae, in particular the red deer (Cervus elaphus), the fallow deer (Dama dama) and the sika deer (Cervus nippon), became relatively popular farmanimals. Deer farming continues to develop, albeit at different rates, in Europe and worldwide. In deer farms, the fulfillment of the Five Freedoms listed in the Codes of Recommendations for the Welfare of Livestock...
The mallard duck (Anas platyrhynchos) is a host to internal and external parasites. A heavy parasite burden indicates poor immunological status and a pathogen-contaminated environment. The present study describes the macroscopic and microscopic examination of isolated intestines and gizzards of 130 mallard ducks from birds kept in the breeding farm. Scrapings of intestinal mucosa were examined by...

The aim of this study was to review recent research, conducted over the last two decades, into prediction of carcass leanness and fatness in live domestic birds. Numerous traits were measured in live birds, and relatively high correlations were found between the breast muscle content and lean meat content of the whole carcass vs. breast muscle thickness, breastbone crest length and body weight of...
The experimental materials comprised 400 Ross 308 chickens (200 ♂ and 200 ♀), divided randomly into four groups kept in 16 pens, as follows: a negative control group (I) – a diet without additives, a positive control group (II) – a diet supplemented with a combination of the antibiotic growth promoter flavomycin (10 mg kg⁻¹ feed) and the coccidiostat robenidine (500 mg kg⁻¹ starter and grower feed),...
Celem przeprowadzonych badań było określenie zawartości: Mg, Ca, Na, K, P, Fe w mięśniach piersiowych kurcząt brojlerów ROSS 308, poddanych w okresie lata 2010 r. różnym wariantom postępowania przedubojowego. W postępowaniu przedubojowym podawano kurczętom w paszy lub w wodzie, przez siedem dni przed ubojem, fitopreparat składający się z: rutwicy lekarskiej (Herb. Galegae), pokrzywy zwyczajnej (Herb...
The aim of this study was to determine the carcass quality and production results of geese fattened on oat following a restricted feeding regime. The experimental materials comprised White Kołuda geese (56 ♂ and 56 ♀) reared to 15 weeks of age. During the first 12 weeks, the amount of feed given to birds was limited by 20% in comparison with the control ration, as follows: group II – from 7 to 12...
