A total of 12 Limousin bull calves were assigned to two feeding groups (6 animals per group) analogous in terms of body weight. Bulls were reared during calfhood with suckler cows and then fed indoors with farm-produced feeds (silages, hay, concentrates) to obtain a body weight gain of approximately 1000 g/day. The basic bulky feed was maize silage (fed ad libitum), supplemented with meadow hay (1 kg/day), and different amounts (according to group) of concentrate (kg/100 kg body weight): 1.0 (group KK-I) or 0.6 (KK-P). The study showed that compared to semi-intensive feeding, intensive feeding of Limousin bulls in the finishing period with diets containing maize silage, meadow hay and concentrate had a more favourable effect on fattening traits, slaughter traits, economic efficiency of feeding and fatty acid profile in the intramuscular fat, n-6/n-3 PUFA ratio and total cholesterol content of the longissimus muscle.

Doświadczenie przeprowadzono na 12 buhajkach rasy Limousine, przydzielonych po 6 sztuk do analogicznych pod względem masy ciała grup żywieniowych. Buhajki odchowywano w okresie cielęcym przy krowach matkach, a następnie żywiono alkierzowo paszami gospodarskimi (kiszonki, siano, treściwe) dla uzyskania przyrostu masy ciała około 1000 g/dzień. Podstawową paszę objętościową stanowiła kiszonka z kukurydzy (skarmiana do woli), uzupełniona sianem łąkowym (1 kg/dzień) i zróżnicowaną (w zależności od grupy) ilością mieszanki treściwej (kg/ 100 kg masy ciała): 1,0 (grupa KK-I) lub 0,6 (KK-P). Badania wykazały, że intensywne żywienie buhajków rasy Limousine w końcowym okresie opasania dawkami zawierającymi kiszonkę z kukurydzy, siano łąkowe i paszę treściwą, wpływa korzystniej w porównaniu z żywieniem pół-intensywnym na cechy opasowe, rzeźne i efektywność ekonomiczną żywienia oraz profil kwasów tłuszczowych w tłuszczu śródmięśniowym o właściwościach prozdrowotnych, stosunek PUFA n-6/n-3 i zawartość cholesterolu całkowitego w mięsniu najdłuższym grzbietu.
