In three separate feeding experiments using a total of twenty-six individually-housed Ayrshire cows, three wilted silages made from Blanca white clover were offered ad libitum with either different supplements or different proportions of grass silage. The clover silages contained 680 g white clover kg−1 on a DM basis, and had a mean DM concentration of 263 g kg−1 with 231 g CP kg−1 DM and 91 g ammonia-N kg−1 N. The pH values averaged 4·16 and the DOMD concentrations 611 g kg−1 . In experiment 1 the daily intake of clover silage given alone was 15.2 kg DM per cow, i.e. 30·1 g kg−1 live weight, and decreased by 0·76 kg DM kg−1 barley DM and by 0·66 kg DM kg−1 barley plus soybean meal DM when these feeds were offered as supplements. Milk yield and fat concentration were higher on the supplement treatments than on the clover silage-only treatment. In experiments 2 and 3 the intakes of silage and total DM increased as the weight of clover in the diet increased from 0 to 700 g kg−1 with parallel increases in milk yield. The effects on milk composition were small and generally non-significant. Although white clover silages with excellent fermentations were made, it is concluded that the main role of white clover in a silage system will be in mixed swards with grass to reduce the input of fertilizer N and to increase the voluntary intake of silage. 相似文献

Blood samples were collected from crossbred dogs rendered transiently hypoglucosaemic or hyperglucosaemic by intravenous injection of tolbutamide or dextrose. Whole blood glucose levels determined with 'Dextrostix' and an 'Eyetone' reflectance colorimeter were compared with plasma glucose levels measured by the hexokinase and ortho-toluidine methods.
The Dextrostix-Eyetone method gave results which correlated well with those obtained by the other two techniques, and the degree of precision attained was judged satisfactory for clinical purposes. The Dextrostix-Eyetone system also has several practical advantages for veterinary clinicians. 相似文献

At 6 weeks of age several Springer Spaniel littermates developed weakness which was exacerbated by exercise and alleviated by rest. Pharmacological testing and electromyographic studies indicated that the disorder resembled human myasthenia gravis. The initial response to neostigmine was satisfactory, but correct maintenance of dosage was difficult and two pups were electively destroyed. During 14 months of observation the third animal has shown continued requirement for treatment. Neostigmine overdose produced signs similar to those of undertreatment, but was recognized by failure to improve after intravenous administration of edrophonium. 相似文献
