Comparison of protein and energy supplementation to mineral supplementation on feeding behavior of grazing cattle during the rainy to the dry season transition
The aim of this study was to evaluate the effects of protein-energy or mineral supplementation on the ingestive behavior of dairy steers on pasture in the post-weaning phase during the rainy to dry season transition. Twenty-two ½ Holstein-Zebu dairy steers with an average initial body weight of 234 ± 16 kg were distributed into a completely randomized design into two groups: protein-energy supp...
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 کاملLevels of Supplementation for Grazing Beef Heifers
The objective of this experiment was to evaluate the effect of providing different levels of a supplement on the nutritional characteristics and productive performance of heifers on pasture during the rainy-dry transition and dry season in Brazil or tropical area. Thirty crossbred heifers with predominance of Zebu breed were used in a completely randomized experimental design. Treatments consis...
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 کاملProtein and selenium levels for growing and finishing beef cattle.
Two feedlot studies were conducted with 96 Hereford steers to assess the relationship be:ween selenium adequacy and protein requirements of growing and finishing cattle. The first study was a 98-day growing trial with feeder steers as they gained from 230 to 340 kilograms. Diets contained 55% corn silage (dry matter basis) with shelled corn and were supplemented with soybean meal and sodium sel...
