New Concepts in Trace Mineral Supplementation of Grazing Cattle Hydroxy Sources, Injectable Sources and Pasture Application
The trace mineral nutrition of grazing cattle is complicated by several factors among which are the impacts of trace mineral antagonists in grazed forage and the reliance on predictable, uniform intake of free-choice mineral supplements. Numerous options are available to assist in the management of trace mineral nutrition of grazing cattle. In recent years, significant research efforts have bee...
متن کاملCopper supplementation of grazing cattle using pasture topdressing and individual animal treatment
Three methods of copper supplementation were compared in 9to 15-month-old Friesian bulls on a farm with a history of copper deficiency. A group of 60 bulls grazed 19 ha which had been topdressed in May with 120 kg copper sulphate (6.3 kg/ha). Five of the bulls were identified for repeated sample collection. A second group of 60 bulls grazed an untreated area and five of these were each given a ...
متن کاملTrace Mineral Supplementation of Grazing Beef Cattle
The nutrient quality of forage, particularly perennial warm-season grasses, is often lacking in trace mineral content to supply the requirements of most all classes of grazing cattle. Since forage is the most significant contributor to the trace mineral nutrition of grazing beef cattle, it is important to consider these deficits and how they may impact the performance of the cattle consuming th...
متن کاملNutritional Performance of Cattle Grazing during Rainy Season with Nitrogen and Starch Supplementation
The objective of this work was to evaluate the effects of supplementation with nitrogen and starch on the nutritional performance of grazing cattle during the rainy season. Five rumen cannulated Nellore steers, averaging 211 kg of body weight (BW), were used. Animals grazed on five signal grass paddocks. Five treatments were evaluated: control (forage only), ruminal supplementation with nitroge...
متن کاملInfluence of supplementation method on forage use and grazing behavior by beef cattle grazing bluestem range.
Two 25-d trials (late summer and early winter) were conducted to determine the influence of supplementation method on forage use and grazing behavior. Fifteen ruminally and 12 esophageally fistulated steers (316 and 400 kg, respectively) were blocked by weight and assigned randomly to one of three treatments: 1) self-feeding supplement (via Calan gates) with salt as a limiting agent; 2) daily h...
