Milk Production Function and Resource use Efficiency in Rajasthan

The study was undertaken in Rajasthan with the objective to examine the input-output relationships and assess the resource use efficiency in milk production. The study covered 60 dairy households. The results of Cobb-Douglas production function revealed that concentrate had positive and significant influence on returns from buffalo, crossbred cow and local cow milk. Green fodder and labour were also significantly influenced the returns from buffalo, crossbred and local cow. The results of resource use efficiency and marginal value productivity of inputs indicated that inputs were not optimally utilized by dairy households. The green fodder, dry fodder, concentrate and labour in buffalo, concentrate and labour crossbred cow milk production and green fodder in local cow milk production were found to be over utilized in study area resulting higher per litre cost of milk production on these species.

Imaging in the Diagnosis of Symptomatic Forearm Muscle Herniation.

Symptomatic muscle herniations are an unusual cause of upper extremity pain that is rarely reported in the literature. Out of 18 reported cases of upper extremity herniations, only 3 were caused by strenuous exertion6. Dynamic ultrasound and Dynamic MRI test are the very good tool for diagnosis of muscle herniation, FNAC and biopsy are rarely needed. This article describes a successful repair of a 22yr old manual worker’s ventral forearm herniation with polypropylene mesh. Prevalence Muscle herniation in an extremity is a well-known cause of pain, even though there have been extremely few documented cases. In a 2009 report published by the “Journal of Hand and Microsurgery,” only 200 cases of herniated muscles of the extremities had been reported since the mid-1800s, and only 17 cases of muscle herniation in the upper limb have been described10. Characteristics A herniated muscle in the forearm can cause mild to severe localized pain, affect grip, cause nerve pain or have no physical symptoms at all. Causes of documented cases include sporting or occupational activities, or an unrelated primary medical condition. Patients usually have a swollen mass that increases in size when the affected muscle is engaged and decreases when the muscles are relaxed. One differential diagnosis for a herniated forearm muscle is a tumor. Muscle herniation in the forearm typically affects males in their adolescent or young-adult years1. We report a case of a disappearing forearm nodule that appeared with muscle contraction. This is characteristic of a transfascial muscle hernia. Ultrasound and MRI are the key to identifying an area of fascial alteration. Treatment alternatives of this unusual condition are discussed.
