Abstract
Kukuruzni škrob iz silaže cijele biljke i silaže zrna je glavni izvor energije u tovu junadi. Siliranje povisuje razgradnju škroba zrna u buragu i probavljivost u tankom crijevu čime se povisuje energetska vrijednost, a moguće je silirati i suho zrno nakon postupka rehidracije. S obzirom da povišena razgradnja škroba može utjecati na probavljivost vlakana, cilj ovog istraživanja je bio usporediti probavljivost vlakana u junadi hranjene škrobom istog hibrida kukuruza u formi suhog ili siliranog rehidriranog zrna kukuruza. Zrno hibrida Bc 572 rehidrirano je do 32% vlage i silirano uz dodatak komercijalnog inokulanta. Pokus je proveden na četiri tovna juneta simentalske pasmine slične težine i starosti, koja su bila raspoređena na obrok sa suhim zrnom i siliranim rehidriranim zrnom kukuruza prema crossover dizajnu u dva perioda od po 17 dana. Kao indikator probavljivosti korišten je kromov(III)‐oksid. Junad hranjena obrokom sa siliranim rehidriranim zrnom kukuruza u usporedbi sa obrokom sa suhim zrnom je imala manju probavljivost (P≤0,05) suhe tvari (57,16% vs. 60,21%) i osobito neutralnih detergent vlakana (45,54% vs. 57,08%). Tretman sa siliranim rehidriranim zrnom kukuruza nije imao značajan utjecaj na pH fecesa kao pokazatelja acidoze.
Abstract (english)
Maize starch from the whole plant silage and grain silage is the main energy source for growing beef cattle. Ensiling increases degradability of grain starch in rumen and digestibility in the small intestine, which increases its energy value, and it is possible to ensile dry grain after rehydration. Since higher starch degradability can affect fiber digestibility, this study aimed to compare fiber digestibility in beef cattle feed starch from the same maize hybrid in the form of dry grain and ensiled rehydrated maize grains. Grain of hybrid Bc 572 was rehydrated to 32% moisture content and ensiled with the addition of a commercial inoculant. The experiment was carried out on four fattening Simmental beef cattle, similar in weight and age, that were assigned to the ration with dry maize grain or ensiled rehydrated maize grain in a cross‐over design with two 17‐day periods. Chromium (III) oxide was added as digestibility indicator. Beef cattle fed with ensiled rehydrated maize grain compared to dry maize grain had a lower digestibility (P≤0.05) of dry matter (57.16% vs. 60.21%) and neutral detergent fiber (45.54% vs. 57.08%). Treatment with ensiled rehydrated maize grains did not have a significant effect on fecal pH as an indicator of acidosis.
