Optimal Calving Time For Beef Cows In Southwest Missouri, Briana Rose Verploeg
Optimal Calving Time For Beef Cows In Southwest Missouri, Briana Rose Verploeg
MSU Graduate Theses
The purpose of this study is to determine if a optimal time of year exists for beef producers to have cows give birth in southwest Missouri for maximal net returns from calf sales and increased cow reproductive performance. To make this determination, data were collected which included year-round forage nutritive value, calf pre-weaning growth, cow energy efficiency and reproductive performance, and income and cost values. Cow and calf field data were gathered for the 2014-2018 production years at Missouri State University’s Leo Journagan Ranch. Monthly forage samples were collected from study cow pastures from 2016 through 2018. Calf, cull cow, …
Alternative Feeding Strategies For Growing Cattle Grazing Endophyte-Infected Tall Fescue During The Summer, Kerri A. Johnson
Alternative Feeding Strategies For Growing Cattle Grazing Endophyte-Infected Tall Fescue During The Summer, Kerri A. Johnson
MSU Graduate Theses
Two experiments were conducted to determine animal performance of alternative feeding strategies to heifers grazing endophyte-infected tall fescue during summer months. In Experiment 1, 40 Limousin heifers (261± 40kg initial BW) were stratified by weight and assigned to either a spring harvested tall fescue silage diet or grazing endophyte-infected tall fescue pasture with grain supplement having either natural or artificial shade for 80 days. In Experiment 2, 40 Limousin heifers (277 ± 44kg initial BW) were stratified by weight and assigned to either a traditional grain supplement or feather-meal supplement (rumen bypass arginine supplement) with natural or artificial shade while …
