A cross slotted electronic band gap (EBG) with stacked rectangular patches shorted with a shorting pin is proposed in this paper. The study is being done on how the various parameters are varied by changing the probe feed location. The design is constructed by using stacking of patches, shorting pin and cross slotted EBG to form an optimized antenna design with antenna efficiency of approximate...

Problem statement: Endogenous enzymes of broilers cannot adequately digest nonstarch polysaccharides and subsequently the ingestion of high levels of soluble NSP leads to increased digesta viscosity and reduced nutrient digestibility and absorption. Supplementation of NSPs degrading enzymes may remove the anti nutritive effects of NSPs and release some nutrients (starch, protein) from these ele...

This paper introduces a new geometry of a rectangular microstrip patch antenna that improves the performance of a conventional microstrip patch antenna .This antenna is designed to operate at 5.38 GHz with enhanced bandwidth of 11.15%. For the desired result, a triangular notch is inserted into the patch antenna. The proposed geometry provides improvement in other radiation parameters like gain...

Selection for the wide range of traits for which most beef breed associations calculate expected progeny differences focus on increasing the outputs of the production system, thereby increasing the genetic potential of cattle for reproductive rates, weights, growth rates, and end-product yield. Feed costs, however, represent a large proportion of the variable cost of beef production and genetic...

Feed efficiency has a major influence on the unit cost of beef cattle production. Gibb and McAllister (1999) have reported that a 5% improvement in feed efficiency has an economic impact four times greater than a 5% improvement in average daily gain. In addition, the cost of feed is second only to fixed costs in importance to the profitability of commercial beef operations (Basarab, 1999). The ...

A 10 week feeding trial was carried out to evaluate the replacement value of hatchery wastes for fish meal in the diet of laying Japanese quail (Coturnix coturnix japonica). 108 female Japanese quails (36 per treatment) were randomly allocated into 3 dietary treatments A, B and C which are fish meal (FM), whole hatchery waste meal (WHWM) and shelless hatchery waste meal (SHWM) based diets respe...

Improving feed efficiency in dairy cattle is a costly and complex challenge, due to the difficulty in measuring individual animal feed intakes and the need to consider energy demands for growth, lactation, maintenance, health, and fertility. Research projects are underway in several countries to provide genomic breeding values for dry matter intake or residual feed intake of dairy bulls based o...

A new feed additive, salinomycin, was fed to 70 finishing steers (initial weight of 772lb) and 70 finishing heifers (initial weight of 4951b) for 139 and 145 days, respectively. Salinomycin was fed at 0, 5, 10, 15, and 20 g per ton of a ground corn based diet. Averaged across salinomycin levels, gain was increased 2.6 percent and efficiency of feed use was improved by 7.8 percent. Feed intake w...
