twenty four multiparous holstein cows in their early stage of lactation with a mean of 59±20 dim and a mean of 615±40.5 kg of bw were employed in a complete randomized block design to evaluate the effects of different levels of sugar beet pulp in a partial replacement for alfalfa, the only source of forage in their previous diet (treat 1, 0% beet pulp and 35% alfalfa, treat 2 ,6% beet pulp and ...

This study investigated the effect of Rumex Sc (commercial product which includes of Saccharomyces cervisiae, saponin and essential oils) on rumen fermentation, blood glucose, urea, milk yield and milk composition. Animals were offered a basal diet containing alfalfa hay (15.5%), corn silage (24%), beet pulp (7%) and concentrate (53.5%). Additionally, Rumex Sc was included in the experimental d...

four-handed fifty lactating holstein cows with mean body weight of, 597± 40 and 50±20 and days in milk body condi from sure of 3.1±0.4 were blocked by parity and randomly assigned to 3 treatments. each treatment had 3 pens and each pen had 50 cows. the experiment lasted for 60 days (10 days adaptation and 50 days collection period). concentrate to forage ratio was 60 to 40 and alfalfa hay repla...

The aim of this study was to evaluate the effect of fat supplementation for enhancing milk conjugated linoleic acid (CLA) in early lactation without affecting ruminal fermentation. 24 Holstein dairy cows were assigned to a completely randomized design employing a 2 × 4 factorial arrangement. Factors were particle size (15 and 25 mm) and two different sources of alfalfa supplemented with and wit...

This study was conducted to determine the chemical composition and nutritive value of sunflower residues silage (SRS) and effects of its substitution with alfalfa hay and corn silage on lactation performance, feed intake, nutrient digestibility and some blood parameters of Mohabadi dairy goats. Four experimental diets were formulated to gradually replace alfalfa hay and corn silage with SRS as ...
