The objective of these studies was to determine the possibility of employing post-extraction rapeseed meals from a bi-zero and mono-zero variety of rape in mixed feed intended for broiler chicken. The experimental birds were given feed containing /instead of the post-extraction soyabean oilmeal/ rapeseed meal of the Jantar variety /15% in DKA starter and 14% in DKA finisher/ and 14% of mono-zero meal...
The study was focused on the evaluation of rapeseed meal of Jantar variety, twice improved, in broiler feeding. In experimental group, 13-15% and 19,5-22,5% of soybean meal was replaced by rapeseed meal and part or the whole portion of maize meal by wheat and barley ground grain. Supplement of 19,5% and 22,5% of rapeseed meal in the mixtures decreased body weight significantly and increased food consumption...
The experimeit was carried out on 1350 Astra В chickens divided into 5 groups. Standard mixture was fed to the control group. In the remaining four groups, the amount of maize meal was decreased and half of the soybean meal replaced by 15/13% of rapeseed meal. The kind and the amount of antibiotic added to the mixtures varied. The mixtures contained 8/6 mg or 12/6 mg of flavomycin per kg or 10/10...
