The nutrition of young and pregnant heifers

Abstract

When raising young and pregnant heifers the correct nutrition is of utmost importance. All phases of nutrition must be known. The female calf, after the age of six months, is planned either for fattening or for breeding, which means that nutrition must vary accordingly. Calves that are left for breeding or replacement in a herd are to be fed in several phases, in accordance with their age, starting from the age of six months till the first calving. Meals must be so composed as to provide both the maintenance ration and the daily growth ration, while care should be taken to avoid an excessive fattening of the progeny. The aim of breeding the progeny is not to fatten it, which would be harmful, but to assist it in achieving a normal weight and a natural daily growth rate, relative to its age in the category of a breeding class.

U odgoju mladih i steonih junica pravilna ishrana je od posebne važnosti i zato se moraju poznavati sve njene faze. Žensko tele posle šest meseci starosti stavlja se u tov ili se ostavlja za odgoj, a to znači da će i tretman ishrane biti drukčiji nego teladi za tov. Telad koja se ostavljaju za odgoj i obnovu stada, hrane se prema uzrastu u više faza, i to od starosti od šest meseci, pa sve go prvog telenja. Obroci moraju biti sastavljeni tako, da udovoljavaju uzdržni deo i deo obroka za dnevni porast, vodeći računa da se ne preforsira u količini hrane, kako ne bi došlo do toga da se podmladak pretovi. Cilj odgoja nije da se podmladak pretovi, što bi bilo štetno, već da ima normalnu težinu i prirodan dnevni prirast prema svojoj starosti u kategoriji grla za odgoj.
