Zauživanje krmne mešanice v molzišču in srčni utrip krav = Feeding of concentrates in milking parlour and heart rate of cowsJanžekovič, Marjan, 1959- ...Analizirali smo krmljenje 27 krav molznic s suho mleto krmno mešanico v molzišču in poskušali ugotoviti ali prekratek čas za zaužitje povzroči stres, ki se odraža tudi s povečanim srčnim utripom ... (SU). Poprečna količina zaužite krmne mešanice pri eni molži je znašala 2,14 kg, krave pa so dobivale od 1 do 5 kg. Hitrost zaužitja suhe krmne mešanice je bila 249,7 g min-1. Pri večerni molži so imele krave večji SU (83,4 min-1) kot pri jutranji (81,2 min-1). Drugi mesec po telitvi je bil SU (85,10 min-1) večji kot prvi (81,04 min-1) in tretji mesec po telitvi (80,79 min-1). Ugotovljeno je bilo, da do količine 3 kg krmne mešanice na molžo ni prihajalo do povečanega SU. Z naraščajočo količino krmne mešanice nad 3 kg je naraščal tudi SU. Pri kravah, ki so dobile največ krmne mešanice, se je SU najbolj pospešil proti koncu molže. Velika količina suhe krmne mešanice, ki je visoko proizvodne krave molznice v molzišču ne morejo požreti v kratkem času molže povzroči pri njih stres.Source: Acta agriculturae Slovenica. - ISSN 1581-9175 (Letn. 86, št. 2, dec. 2005, str. 75-83)Type of material - article, component partPublish date - 2005Language - slovenianCOBISS.SI-ID - 1829768
