Producing High Quality Orchardgrass and Timothy Hay
Forage quality of orchardgrass and timothy hays can be evaluated from both nutritional and marketing perspectives. From the nutritional perspective it is conditioned by the 1) nutrient concentration, 2) rate of voluntary intake, 3) digestibility and 4) partitioning of metabolized products within the animal. From the marketing perspective, hay destined for urban feed store and Pacific Rim market...
متن کاملEffects of supplemental alfalfa hay on feed intake and digestion by Holstein steers consuming high-quality bermudagrass or orchardgrass hay.
Effects of level and frequency of supplementation with alfalfa (A) on feed intake and digestion by steers fed bermudagrass (B) or orchardgrass (O) were determined in two Latin square experiments. In Exp. 1, six Holstein steers (224 kg) were fed B (2.25% N; 71.4% NDF) or O (2.52% N; 64.3% NDF) with 0, 15 or 30% (DM) A (2.70% N; 44.0% NDF). Total DMI was 2.43, 2.72 and 2.85% BW for B and 2.98, 3....
متن کاملMicrostructure of skeletal muscles of growing calves fed silage-based vs hay-based diets. II. Fibre type distribution.
As described in part I, samples of musculus longissimus dorsi, semimembranosus and semitendinosus were obtained post-slaughter from 2-week, 3-month and 10-month-old bull calves. The 2-week-old calves were fed milk only. All the remaining animals were fed grass silage or hay ad lib and a restricted amount of concentrate from 2 weeks of age onwards. Muscle fibres were differentiated according to ...
متن کاملMicrostructure of skeletal muscles of growing calves fed silage-based vs hay-based diets. I. Fibre diameters.
Samples of musculus longissimus dorsi, semimembranosus and semitendinosus were obtained post-slaughter from 2-week, 3-month and 10-month-old bull calves. The 2-week-old calves were fed milk only. All the remaining animals were fed grass silage or hay ad lib and a restricted amount of concentrate from 2 weeks of age onwards. Muscle fibres were differentiated according to Ziegan into fast-twitch ...
متن کاملBacterial communities in the rumen of Holstein heifers differ when fed orchardgrass as pasture vs. hay
The rich and diverse microbiota of the rumen provides ruminant animals the capacity to utilize highly fibrous feedstuffs as their energy source, but there is surprisingly little information on the composition of the microbiome of ruminants fed all-forage diets, despite the importance of such agricultural production systems worldwide. In three 28-day periods, three ruminally-cannulated Holstein ...
