Not AvailableOn-farm lactation trial of 4 months duration was conducted in Anagalpura and Menesi village of Doddaballapura taluk, Bangalore district in Karnataka state to study the effect of feeding bypass protein (UDP) on the milk production performance of crossbred cows. Crossbred cows (24) yielding 8 to 10 litres of milk/day were divided into 2 comparable groups (control and experimental) of 12 each based on lactation number, milk yield and days after calving. Cows in control group were fed a concentrate mixture (CMC) which contained 37% of CP as UDP (bypass protein), while those in experimental group were fed a concentrate mixture (CME) containing 50% CP as UDP. The animals in both the groups were fed ad lib. local mixed grass as the major source of roughage. The average milk yield per day in experimental group was significantly higher than those in control group. The milk fat, SNF and total solids were significantly higher in experimental animals than in control group animals. The milk yield was increased by 1.07 litres, feed cost was reduced by Rs 2.20 and the overall income of the farmers was increased by Rs 12.40/cow/day in experimental group. The study indicated that feeding of bypass protein increased quantity and quality of milk in cows producing 8_10 litres milk/day on local mixed grass based diets.Not Availabl

A Wideband Conical Beam Cylindrical Dielectric Resonator Antenna

The letter proposes a novel cylindrical dielectric resonator antenna (DRA) geometry with low radiation Q-value facilitating wide band operation with conical radiation patterns. The DRA is fed by a microstrip transmission line with a vertical strip that is attached to the DRA surface. At optimum dimensions and position of the vertical strip on the horizontal microstrip, the DRA exhibits an impedance bandwidth ( $vert {rm S}_{11}vert < - 10$ dB) of {sim}35hbox{%} at the centre frequency of 3 GHz. Measured radiation patterns are conical in shape and are stable with moderate gain across the matching band

Microstripline fed Half-Cylindrical Dielectric Resonator Antenna for 2.4 GHz WLAN application

A compact half-cylindrical dielectric resonator antenna (DRA) made from a high-permittivity (εr = 69) ceramic material is investigated. A microstrip transmission line excites the DRA. The DRA shows broad and stable radiation characteristics across a matching band of 2.32 to 2.5 GHz with peak gains of 5.5 dBi in the elevation plane and 3.6 dBi in the azimuth plane. The results lead us to propose this DRA for 2.4-GHz WLAN (2.4 to 2.484 GHz) applicatio
