A comparison of feeding hay to heifers on bluestem pasture and in drylot

This study was designed to evaluate mature dry winter pasture for animals fed all of the harvested roughage such as hay that they would consume. In addition one group animals wintered in drylot were moved to pasture one month prior to the start of the summer growing season to study their adjustment to pasture

Feeding two levels of alfalfa hay to heifer calves on winter bluestem pasture and a three-year summary

This experiment was designed to collect data in regard to the optimum level of alfalfa hay feeding for calves wintered on bluestem pasture. One group of heifers was fed twice as much alfalfa hay as another, but the supplemental total digestible nutrient intake was maintained at about the same level by feeding grain to heifers on the lower level of alfalfa hay. Two previous tests are reported in Circulars 349 and 358

Field-conditioned alfalfa hay as it affects the winter performance of weaned heifer calves

Through cooperative efforts of the Departments of Agronomy and Agricultural Engineering, fourth-cutting alfalfa hay was made available to winter-feed weaned heifer calves. The object of the experiment was to determine the effects of various field-conditioned alfalfa hays on the winter performance of heifer calves

Studies on shipping fever and shipping shrink in cattle

This is the second year in which an attempt was made to determine some basic facts related to shipping fever and shipping shrink in weaned stocker calves. As in the previous years, the calves used in this study were from Jeff Ranch, Fort Davis, Texas. They were gathered early October 21, 1960, weaned from the cows, loaded into trucks, and transported 50 miles to loading pens in Alpine, Texas

Search for dark matter produced in association with heavy-flavor quark pairs in proton-proton collisions at √s=13TeV

A search is presented for an excess of events with heavy-flavor quark pairs (tt¯ and bb¯) and a large imbalance in transverse momentum in data from proton–proton collisions at a center-of-mass energy of 13TeV. The data correspond to an integrated luminosity of 2.2fb-1 collected with the CMS detector at the CERN LHC. No deviations are observed with respect to standard model predictions. The results are used in the first interpretation of dark matter production in tt¯ and bb¯ final states in a simplified model. This analysis is also the first to perform a statistical combination of searches for dark matter produced with different heavy-flavor final states. The combination provides exclusions that are stronger than those achieved with individual heavy-flavor final states. © 2017, CERN for the benefit of the CMS collaboration
