Comparison of Florigraze and Arbrook Rhizoma Peanut Under Continuous Grazing
Florigraze and Arbrook are the most widely used cultivars of perennial peanut in Florida, but their persistence and cattle weight gains have not been compared under continuous grazing. The objectives of this experiment were to evaluate the nutritive value and persistence of both cultivars, as well as to compare the performance (ADG) of 400-lb heifers continuously grazing the two cultivars. In t...
متن کاملMilk production of fall-calving dairy cows during summer grazing of grass or grass-clover pasture.
Milk production of fall-calving dairy cows during subsequent summer grazing was evaluated in two consecutive years using a total of 80 mid- to late-lactation Holsteins. Cows calved during September and October and grazed from April to August in the following year. In yr 1, 27 cows grazed a native grass pasture and 13 cows grazed a native grass-clover mixed pasture containing 26% red clover and ...
متن کاملEffects of livestock breed and grazing intensity on biodiversity and production in grazing systems. 4. Effects on animal diversity
Finding an optimal balance between livestock production and grazing impact on animal diversity is important for the development of sustainable grazing systems. This paper tests the hypothesis that extensification of grazing management enhances animal diversity. Similar treatments were applied over a period of three years to sites in the UK, France, Germany and Italy. There were three treatments...
متن کاملOptimization of Single Cell Protein Production from Cheese Whey Under Batch and Continuous Cultivation
In this research the microorganism was initially isolated and selected after evaluation based on COD reduction of cheese whey and biomass production. The selected microorganism was identified as Trichosporon sp. The cultivation conditions of the microorganism were optimized under batch: temperature 30˚C initial pH = 6 aeration speed = 2 ν.ν.m and agitation rate: 800 rpm. Under these conditions,...
متن کاملExtending Grazing In Heifer Development Systems Decreases CostWithout Compromising Production
Three experiments compared heifer development systems. In Exp. 1, 299 heifers (253 ± 2 kg) from 3 yr were used to compare dry lot (DL) to grazing corn residue (CR) post weaning. Heifers in the DL consumed a common diet after weaning for 187 d until breeding. The CR heifers grazed for 145 d with a supplement (0.45 kg/d; 28% CP) and were then fed in the DL until breeding. In Exp. 2, 270 heifers (...
