Strategies for Reducing Stored Feed Requirements

A basic, desirable goal for virtually any livestock producer is to minimize stored feed requirements. It is less expensive to have livestock harvest forage for themselves by grazing than to harvest it for them; therefore, the greater the extent to which pasture can be used to provide nutrition, the more profitable a livestock operation will generally be. Thus, it is worthwhile to consider all o...

A mechanistic model for predicting the nutrient requirements and feed biological values for sheep.

The Cornell Net Carbohydrate and Protein System (CNCPS), a mechanistic model that predicts nutrient requirements and biological values of feeds for cattle, was modified for use with sheep. Published equations were added for predicting the energy and protein requirements of sheep, with a special emphasis on dairy sheep, whose specific needs are not considered by most sheep-feeding systems. The C...

Requirements for Subreflector and Feed Positioning for ALMA Antennas

This memo presents some calculations related to requirements on subreflector and feed positioning for the ALMA antennas. In order to keep gain loss at less than 1%, the axial (vertical) positioning error in the subreflector should be less than about 0.09 λ, and in the feed should be less than about 0.9 λ. The lateral positioning error for the subreflector should be less than about 0.45 λ, and f...
