sixteen multiparous lactating buffaloes after 8 weeks of calving and weighing 500 to 600 kg were used in a complete switch-back design with four groups. buffaloes in the first group were fed the control ration (r1) consisted of dm basis of 60% concentrate feed mixture (cfm)+20% rice straw (rs)+20% berseem hay (bh), while in the other groups the rations consisted of dm basis of 40% cfm+20% rs+40...

We describe a general approach for using linearizing feedforward control terms for large degree of freedom (dof) multi-limb robots operating in scenarios involving motion and force constraints and under-actuated dofs arising from the task and the environment. Our solution is general and has low computational cost needed for real-time control loops. It supports the tuning of the feedforward term...

On a life-cycle basis, beef animals are able to consume large amounts of low-cost, low-quality forages relative to higher-cost concentrates compared with pigs and chickens. However, of the 3, beef is still more expensive to produce on a cost–per–edible pound basis. Accordingly, there is need for genetic programs and management changes that will improve efficiency, sustainability, and profitabil...

Aim The purpose of this study was to know the production performance and economic analysis in quail which use probiotic supplementation to alternate antibiotic growth promoter (AGP) to feed consumption, water consumption, egg production, egg mass, feed conversion, and feed efficiency. Materials and Methods About 240 quails (Coturnix coturnix japonica) at 14 weeks of age were completely random...
