Abstract
The use of direct-fed microbials has been shown to enhance digestion in the ruminant. One source of a live microbial population is a yeast culture of Saccharomyces cerevisiae (Yea-Saccâ1206, CBS 493.94, EC5). The goal of the trial was to evaluate the influence of Yea-Saccâ1206 on dry matter intake of dairy cows fed a TMR under north-Italian conditions. Ninety eight Holstein dairy cows were randomly assigned for 150 days to one of two groups: (C) Control ration anf (YS) Control ration plus Yea-Saccâ1206 (5.61 x 107 CFU/kg of complete feedingstuff at 880 g DM). The control total mixed ration consisted of maize silage, alfalfa hay, alfalfa pellet, hulled sunflower, maize meal, cane molasses, extruded flax and minerals. The average analysis of the ration was: 62.5% dry matter; 16.5% crude protein; 16.1% crude fiber; 20.1% starch; 37.9% NDF; 19.8% ADF. The diet was distributed to the cows once a day in the morning. The quantity of feed offered and refused by each group was recorded daily. The YS group consumed on average significantly (P<0.10) more DM than the C group (respectively 24.29 vs 23.91 kg DM/cow/day). Interestingly, the difference in consumption could be considered in two time periods: - Summer period (June to August): YS increased intake by >1 kg DM in comparison with Controls (+ 5.54%; P<0.01); - The winter period (October to February): YS increased intake significantly (P<0.10) compared to controls. No differences were detected during the month of September, November, January, March and April. Intake was significantly increased over the whole period with better efficiency during the summer period, which typically entails a decrease in intake and production.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
