Estancia Vs. Kentucky 31: Examining Leaf Nutrient Content Of Established Tall Fescue, Macie W. Clark
Estancia Vs. Kentucky 31: Examining Leaf Nutrient Content Of Established Tall Fescue, Macie W. Clark
MSU Graduate Theses
In 2020 Missouri ranked third in beef cattle production and second in hay production. As part of the fescue belt of the United States, Missouri’s agricultural industries rely on tall fescue (Lolium arundinaceum Schreb.) as a main forage crop. Two major disorders in cattle grazing tall fescue are fescue toxicosis and grass tetany. Fescue toxicosis occurs when animals consume toxic ergot alkaloids produced by an endophyte within the tall fescue plants. The most commonly grown tall fescue variety, Kentucky 31, is infected with the toxic endophyte. Varieties containing a novel non-toxic endophyte, such as Estancia, have been developed to …
Establishing Agroforestry Silvopasture Systems In The Missouri Ozark Region, Kara Lynn Powelson
Establishing Agroforestry Silvopasture Systems In The Missouri Ozark Region, Kara Lynn Powelson
MSU Graduate Theses
The Missouri Ozarks is located in the south-central part of Missouri, ranging from the very southwest corner of the state and east to St. Louis. This region is enriched with large dense populations of oak and hickory tree species, while also being occupied with prime forage pastures for livestock grazing. Missouri is ranked second in the nation for farming operations and hay production, while also third in the nation for beef cow number of head (MDA 2021). The objective of this study is to observe the establishment of two separate silvopasture systems: a planted walnut plantation and a converted silvopasture. …
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, …
Role Of Methionine In Fetal Development Of Beef Cattle, Colin D. Chalk
Role Of Methionine In Fetal Development Of Beef Cattle, Colin D. Chalk
MSU Graduate Theses
The objective of this study was to evaluate whether total amino acids (AA) or methionine have an effect on fetal programming of calves using 108 Angus Brangus cows. Treatments were 1) Control, limpograss hay with molasses plus urea (16% CP as fed basis) at 2.72 kg./hd/d, 2) Fishmeal, Control plus 0.33 kg./hd/d of fishmeal ( methionine 2.85 % of RUP), and 3) Methionine, Control plus 10 g/hd/d of MetaSmart liquid (Addisseo Alpharetta, GA) . Fishmeal and Methionine treatments supplied similar amounts of metabolizable methionine. Weight of cows and calves along with body condition score of cows were measured at the …
Macronutrient Content Of Winter Annual Cereal Grains With Phosphorus Fertilization, Taylor Anne Young
Macronutrient Content Of Winter Annual Cereal Grains With Phosphorus Fertilization, Taylor Anne Young
MSU Graduate Theses
Missouri ranks third in the United States in cow-calf production, and much of the land these cattle graze has acidic soil that is low in plant available phosphorus (P). Proper soil fertility is important to ensure that these forages meet the nutritional requirements of cattle. Tall fescue (Festuca arundinaceum (Schreb.)), has been shown to respond to increased soil P levels with increased growth and leaf concentrations of P, calcium (Ca), magnesium (Mg), and potassium (K). It is unknown if winter annual cereals will respond similarly. The objective of this study is to examine cereal rye (Secale cereal L.), winter wheat …
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 …
Management And Production Practices Of The Missouri Beef Cattle Industry, Jordan Lee Kinder
Management And Production Practices Of The Missouri Beef Cattle Industry, Jordan Lee Kinder
MSU Graduate Theses
A survey of beef cattle producers in Missouri was conducted to evaluate the management and production practices of the beef cattle industry. Production and demographic data from 112 (response rate of 5.9%) were analyzed to identify areas in need of future research and education. The web-based survey was conducted through Survey Monkey© and distributed by the Missouri Cattlemen's Association to a list of their members. Responding producers were located in 65 of the 114 counties in Missouri, with 63.3% located north of Interstate 44 and 36.7% south of Interstate 44. The majority (47.3%) of producers were between ages 31 and …
