Impact Of Phosphorus Intake On Beef Heifer Growth Performance And Conception Rates, Hailey Hilfiker 2020 University of Arkansas, Fayetteville

Impact Of Phosphorus Intake On Beef Heifer Growth Performance And Conception Rates, Hailey Hilfiker

Animal Science Undergraduate Honors Theses

This study aims to examine the effects of phosphorus intake on beef heifer growth performance and conception rates. In Northwest Arkansas, there has been an increase in phosphorus concentrations in soil where livestock manures have been repeatedly applied. Consequently, forages grown on soils high in phosphorus tend to contain high amounts of the mineral itself. This has led many to question whether it is necessary to supplement phosphorus in areas where concentrations may be higher. In this study, crossbred Angus heifers (n = 72), approximately 30 days after weaning, were stratified by body weight (average initial weight 251 ± 3.9 kg ...

Calf Heath And Oxidative Stress, Samantha Cardin 2020 University of Rhode Island

Calf Heath And Oxidative Stress, Samantha Cardin

Senior Honors Projects

In recent years, beef cattle operations such as farms and ranches in the U.S. have surpassed 900,000 and have been steadily increasing. With this rise in the beef industry, comes a greater concern for calf health since it has huge impacts on production and viability. There are multiple different factors that can affect calf health ranging from the intrauterine environment to conditions early on post parturition. An improper maternal environment during pregnancy can impact fetal growth because it can decrease the amount of nutrients reaching the calf. This can lead to low birth weights and undeveloped organ systems ...

An Efficient Stocking Strategy For Grazing Replacement Heifers, Keith R. Harmoney, John R. Jaeger 2020 Kansas State University

An Efficient Stocking Strategy For Grazing Replacement Heifers, Keith R. Harmoney, John R. Jaeger

Kansas Agricultural Experiment Station Research Reports

Even though Kansas native rangelands often have steep slopes or shallow soils not con­ducive to many other uses other than livestock grazing, native rangeland and perennial grassland acres in Kansas have been declining. Cropland acreage over this same time frame has increased, and rangelands have also become more fragmented by small ranch­ettes and urbanization. Producers may be looking to increase production efficiency on a shrinking forage land base. The use of intensive early stocking (IES) is one of the most efficient stocking strategies to produce beef on rangeland acres. The IES strategy has been widely used in eastern ...
