Age as a factor in animal breeding
(University of Missouri--Columbia, 1911)
comprehensive nor far-reaching. Director F.B. Mumford of the Agricultural Experiment Station at the University of Missouri first conceived the idea of conducting an experiment for the determination of the proper age of animals for breeding. Unfortunately...
A study of the treatment of the intestinal parasites of swine
(University of Missouri--Columbia, 1914)
progress, gains a firm foot-hold on the affected animal before its presence is suspected and is especially injurious to young, poorly fed shoats. Older hogs when properly fed are able to withstand its attacks for some time before any noticeable symptoms...
Effects of essential oils on the performance, health, and feeding behavior of growing cattle
(University of Missouri--Columbia, 2021)
. Essential oils are reported to alter ruminal fermentation (Hart et al., 2008) and animal performance (Calsamiglia et al., 2007). There is also evidence to suggest that EOs may manipulate feeding behavior in cattle (Tager and Krause, 2011). An experiment...
The effects of various planes of nutrition upon the cost of maintenance, reproduction, and development of beef cows
(University of Missouri--Columbia, 1916)
The frequency with which valuable animals reproduce themselves has always been a factor of economic importance in the pure bred cattle business. Great economic changes during the last few years have made this an important ...
The influence of breeding young swine upon the parents, the offspring and the breed
(University of Missouri--Columbia, 1913)
has long been known as a swine-producing country of surpassing excellence, and claims to produce and consume more pork than any other nation. Missouri alone, in 1907. sent to market 3,878,863 head of hogs valued at $38,788,630, and at that time...
Increasing land and forage utilization by Missouri cow/calf operations using silvopasture practices
(University of Missouri--Columbia, 2006)
. Two experiments were conducted primarily focusing on methods which allow producers to improve the number of animal grazing days on their operations by implementing silvopastoral systems and increasing forage quality of pastures by applying legumes...
Determining the efficacy of a biosensor to detect calpastatin, a meat tenderness indicator
(University of Missouri--Columbia, 2007)
An instrumental tenderness detection system used at the time of grading to sort beef carcasses on their predicted tenderness would be valuable for the beef industry. A biosensor to accurately predict calpastatin, the ...
The value of in-breeding in the improvement of the domestic animals
(University of Missouri--Columbia, 1917)
In this paper I shall take the stand of a neutral, and all literature and available material of value upon the subject both for and against, will be studied with a view of determining our present knowledge of in-breeding ...
Approaches for alleviating toxic effects of aflatoxin in lactating dairy cows and weanling pigs
(University of Missouri--Columbia, 2010)
and death in humans and animals, safe, practical and effective strategies for alleviating or preventing the toxic effects of AF are highly desirable. Therefore, two experiments were conducted to evaluate two approaches for reducing the toxic effects...
Implications of ovarian and uterine maturity evaluated in replacement heifer candidates
(University of Missouri--Columbia, 2021)
of heifers via reproductive tract evaluation. Disparities in ovarian and uterine maturity may be detected at the time of evaluation in peripubertal heifers. Two experiments were conducted to characterize the incidence and implications of disparate ovarian...
Comparison of thermoregulatory mechanisms in heat sensitive and tolerant breeds of Bos taurus cattle
(University of Missouri--Columbia, 2008)
or minus] 7.5 Kg BW) steers from USDA-ARS, Brooksville, Florida were transported to the Brody Environmental Center at the University of Missouri. Steers were housed for 14 days at thermoneutrality (21C; TN) before 14 days of cyclic heat stress (HS; 26C...
Factors affecting neonatal beef calf metabolism and vigor
(University of Missouri--Columbia, 2021)
Two studies were conducted to investigate factors affecting neonatal beef calf metabolism and vigor. In the first study, effects of late gestational nutrient restriction on colostrum yield, neonatal vigor, and blood chemistry ...
Comparison of controlled internal drug release (CIDR)-based protocols to synchronize estrus and facilitate artificial insemination (AI) in postpartum beef cows
(University of Missouri--Columbia, 2008)
and CO-Synch + CIDR protocol was developed. To date, however, the literature is devoid of information comparing the 7-d and 5-d protocols on the basis of their practical application in the field. Experiment 1 was designed to fully characterize and compare...
Ruminal degradation of protein and carbohydrate in the domestic and wild ruminant
(University of Missouri--Columbia, 2010)
protein (RUP) for the animal. The first experiment in this study examined the level of feed-grade crystalline amino acids (AA) required in a diet to provide appreciable levels of limiting AA as RUP. The solubility of these AA in a mixed rumen culture...
Identification and quantification of differentally represented transcripts in preimplantation bovine embryos
(University of Missouri--Columbia, 2007)
.01) in at least one pairwise comparison. Fifteen of these transcripts were selected for further examination using quantitative real-time PCR, which confirmed that nine of the 15 transcripts were significantly differentially represented in at least one pairwise...
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, ...
Growth, performance and quality attributes of steers supplemented with high oleic soybean oil
(University of Missouri--Columbia, 2019)
Growing concerns with saturated fatty acids on human health has led to research being done to reduce saturated fatty acid levels in animal tissues. The objective of this study was to evaluate the effect of high oleic soybean ...
Estimates of correlation between estrus behavior and estradiol concentrations during estrus
(University of Missouri--Columbia, 2020)
-class correlation (r) for rump touches and steps was approximately 0.45. Experiment 3 focused on the association between circulating concentrations of estradiol and overt phenotypes for estrus [greater activity and (or) rump touches (mounts, chinrests, etc...
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 ...
