Digestible lysine and threonine requirements of male turkeys and their effects on performance of male turkeys fed practical diets to market age
(University of Missouri--Columbia, 2008)
Seven experiments were conducted to determine the minimum requirements of digestible lysine (dLys) and digestible threonine (dThr) from 1 to 21 weeks of age for male turkeys. Requirement values were similar to NRC (1994) ...
Alleviation of heat stress with Tasco in dairy cows
(University of Missouri--Columbia, 2010)
The present study determined the impact of Tasco, Ascophyllum nodosum, on heat stress in dairy cows. Thirty-two Holstein cows were utilized in a randomized complete block design, during 63 days in summer 2008. Feed intake, ...
Determination of fat percentage using three different methods within marbling scores on beef longissimus muscle
(University of Missouri--Columbia, 2010)
Consumers are concerned with fat consumption from meat products and the ability to determine fat has changed with recent technological advances. The objective of this study was to determine fat percentage within marbling ...
Ruminal degradation of protein and carbohydrate in the domestic and wild ruminant
(University of Missouri--Columbia, 2010)
To optimize growth and health ruminant animals in a confined setting, diets need to be formulated to provide balanced levels of rumen degradable energy and nitrogen (RDN) to maximize microbial growth while also providing ...
Progestin regulation of follicular dynamics in beef cattle
(University of Missouri--Columbia, 2009)
Progestins, such as melengestrol acetate (MGA) and Controlled Internal Drug Release (CIDR), can inhibit ovulation and synchronize estrus in cattle. However, long-term MGA treatment, in the absence of a corpus luteum, results ...
Improvement of feed efficiency in beef cattle through selection upon residual feed intake (RFI)
(University of Missouri--Columbia, 2010)
Selecting beef cattle which metabolically are more efficient at converting feed into gain or body weight maintenance is one way to reduce feed cost in beef production. Residual feed intake (RFI) is one trait used to identify ...
Approaches for alleviating toxic effects of aflatoxin in lactating dairy cows and weanling pigs
(University of Missouri--Columbia, 2010)
Aflatoxin (AF) is a mycotoxin found in feed ingredients used in livestock diets including dairy cattle and pigs. Aflatoxin causes reduced performance, liver damage, increased prevalence of infectious disease, and secretion ...
Influence of subclinical hypocalcemia on plasma biochemical parameters, liver histologic changes, and common postpartum diseases in dairy cows
(University of Missouri--Columbia, 2011)
We hypothesized that cows with subclinical hypocalcemia at calving would have greater elevations in liver associated biochemical parameters and non-esterified fatty acid (NEFA) concentrations compared to normocalcemic cows. ...
Effects of dietary melamine and cyanuric acid in young broilers and turkey poults
(University of Missouri--Columbia, 2011)
Six studies were conducted to determine the individual and combined toxicity of melamine and cyanuric acid (up to 3.0%) in young broilers and turkey poults. Melamine alone caused reduced growth, increased kidney weights, ...
Timing of ovulation in gilts treated with different regiments of OvuGel(R) and Matrix(R)
(University of Missouri--Columbia, 2015)
Previous research has shown that 85% of gilts treated with Matrix(R) will show heat (estrus) 4-9 d after last Matrix(R) feeding. Synchronization of estrus is important in knowing when to inseminate (breed). This window of ...
Mu-synthesis controller design for temperature control of a solar steam gasifier with uncertainty modeling and robust analysis
(University of Missouri--Columbia, 2015)
Gasifiers operate by inputting a carbon rich material, water, and heat into a reactor core to cause a chemical reaction to produce a desired chemical composition output. For this work, a unique hybrid allothermal/autothermal ...
Evaluation of in vitro and in vivo equine microbial population shifts in response to colic conditions
(University of Missouri--Columbia, 2011)
We designed two continuous culture experiments to test the effects of starch dosage and starvation upon equine fecal microflora. Diets were designed containing fructooligosaccharides and mannanoligosaccharides in order to ...
Relative influence of the sire and dam upon the inheritance of speed in standard trotting horses
(University of Missouri--Columbia, 1915)
Since the study of the transmission of character began, a diversity of opinion has existed and some data have been secured upon the relative influence of sire and dam in the production of offspring. From the limited data ...
Effects of supplementation of dietary antioxidants and chelated trace minerals in periparturient dairy cows and subsequent response to intramammary bacterial challenge
(University of Missouri--Columbia, 2014)
Two experiments were conducted to investigate the effects of supplementation of synthetic dietary antioxidants and different sources of a blend of trace minerals on two distinct situations of immune dysfunction in dairy ...
Effects of heat stress and fescue toxicosis on the immune system and other physiological parameters
(University of Missouri--Columbia, 2010)
Tall fescue is widely used as pasture grass in the United States, and is the most important cool season grass for grazing animals. Certain fungi also grow on these grasses which produce toxins, resulting in reduced feed ...
Beef chuck muscle isolation has no effect on premium ground beef programs
(University of Missouri--Columbia, 2014)
This experiment evaluated whether isolating certain muscles from the chuck for retail sale and excluding them from the ground beef mix changes the number of days that ground chuck is acceptable to consumers. Chucks were ...
Improving fiber by-product utilization in high concentrate diets
(University of Missouri--Columbia, 2013)
The effects of starch and fiber combinations in feedlot diets were examined to determine maximum whole shell corn (WSC) inclusion rate in high fiber diets and determine the effects of fibrolytic enzyme addition to WSC diets ...
Synchronization and ovarian development in dairy cows and heifers
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Reproductive management is an important factor for improving reproductive efficiency in the dairy industry. Reproductive efficiency affects the ...
Applying effective energy concept for intake prediction and balancing ruminal nitrogen and post-ruminal amino acid requirements for beef cattle
(University of Missouri--Columbia, 2013)
Proper animal nutrition involves balancing nutrient supply to nutrient requirement. Accurate intake prediction is fundamental to diet formulation and appears simple but has historically been challenging to accomplish. ...
Essential oil effects on rumen fermentation, animal performance, and meat quality of beef steers
(University of Missouri--Columbia, 2013)
Efficiency in ruminants has historically been improved by using antibiotics and ionophores to alter rumen fermentation. Nutritionists, however, have begun searching for alternative rumen modifiers due to the negative ...
