Because of concerns about ruminant diets, many researchers are investigating ways to alter what livestock eat and to mix the best of old cow pastures -- diverse, naturally growing, nutrient rich grasses and plants -- with the best of the new -- fast-growing and resistant to invasive species. One possibility is to increase the ability of beneficial, nutrient-rich plants and flowers to grow alongside the fast-growing grasses commonly used in pastures. Another branch of research focuses on plants that are high in tannins , which are believed to lower methane levels in ruminants and to boost milk production -- although excessively high level of tannins are harmful to a ruminant's growth.
The economics of breeding and raising Belgian Blue cattle are inconclusive because of complications experienced during parturition and metabolic demand for increased concentrated feeds. The breed's increased need to have Caesarean sections when calving means increased cost and added work, and can become a welfare issue. [ citation needed ] However, the carcass value of double-muscled animals may be enhanced due to increased dressing yield, lean carcass content, and upgrading of some cuts leading to a higher proportion of higher valued cuts.  The slower rate of fat deposition causes slaughtering to be delayed in most cases, which means an increase in maintenance costs in those animals. Belgian Blue cattle require more skilled management and do not thrive in harsh environments.  For these reasons and others, the breed's overall production efficiency in an economic sense is still unclear.
The National Heart, Lung, and Blood Institute (NHLBI) recommended dosing for systemic prednisone, prednisolone, or methylprednisolone in pediatric patients whose asthma is uncontrolled by inhaled corticosteroids and long-acting bronchodilators is 1–2 mg/kg/day in single or divided doses. It is further recommended that short course, or "burst" therapy, be continued until the patient achieves a peak expiratory flow rate of 80% of his or her personal best or until symptoms resolve. This usually requires 3 to 10 days of treatment, although it can take longer. There is no evidence that tapering the dose after improvement will prevent a relapse.
