Dietary chromium yeast supplementation length in diets for growing-finishing pigs

چکیده
ABSTRACT This study aimed to evaluate different periods of chromium yeast (CrY) supplementation on growth performance and quantitative carcass characteristics growing-finishing pigs. We used eighty barrows (Duroc/Pietran × Large White/Landrace) with an initial body weight 24.5±2.4 kg. A completely randomized block design was within four dietary CrY (control diet: CrY-free, from 25 110 kg; Cr25-110 kg: diet 0.4 mg kg−1 CrY, Cr50-110 50 Cr70-110 70 kg), ten replicates two animals each. The did not affect (P>0.05) either the grow or evaluated. for pigs (25 kg) does alter neither characteristics.

In this study, organically raised pigs received an increasing proportion of grass silage up to 10 and 20% dry matter in the daily ration in the grower and finisher period, respectively, to determine the effects of grass silage on feed intake and growth performance. The pigs receiving a mixture of grass silage and compound feed ingested 0.3 kg DM/d (13% of their daily ration) as grass silage and...
