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 ...
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 ...
Establishment of a phenotypical model of adverse outcomes associated with assisted reproductive technologies
(University of Missouri--Columbia, 2011)
Beckwith-Wiedemann syndrome (BWS) is a loss-of-imprinting pediatric overgrowth syndrome. BWS is speculated to occur primarily as the result of the misregulation of imprinted genes associated with two clusters on chromosome ...
To what extent does a steer grow during process of fattening
(University of Missouri--Columbia, 1910)
Three steers, numbered 18, 121, and 48, were chosen from the group of regular maintenance steers, on an experiment at the University of Missouri to find out the uses to which an animal puts its food.
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 developmental liver transcriptome of Rattus norvegicus
(University of Missouri--Columbia, 2012)
Our research is involved in the transcriptional dynamics of perinatal liver development. The transcription factors and their downstream effects have been well studied in regards to early liver development, yet perinatal ...
Age as a factor in animal breeding
(University of Missouri--Columbia, 1911)
Many breeders believe in the evil effect of early reproduction. It is said that early marriage has led to the degeneracy of many nations. The domestic animals are national assets and their preservation, like the conservatives ...
Corn preparation for fattening lambs
(University of Missouri--Columbia, 1916)
The question of the advisability of grinding grain for farm animals is one which is causing a great deal of discussion at the present time. Theoretically it would be expected that any preparation of a feed, for any class ...
Size-dependent acquisition of global DNA methylation in oocytes is altered by hormonal stimulation
(University of Missouri--Columbia, 2011)
Administration of exogenous gonadotropins (superovulation) is used to increase the number of mature oocytes to circumvent the inefficiencies of the subsequent assisted reproductive technologies procedures. Some evidence ...
Effects of dietary melamine and cyanuric acid in young Pekin ducks and weanling pigs
(University of Missouri--Columbia, 2012)
In 2007, melamine (MEL) and cyanuric acid (CYA) were added to feed ingredients in an attempt to artificially increase their crude protein and thus their momentary value. However, once ingested MEL and CYA can form insoluble ...
Mitochondrial complex I protein is related to residual feed intake in beef cattle
(University of Missouri--Columbia, 2011)
Residual feed intake (RFI) is a calculated using DMI as dependent variable and metabolic body weight (BW 0.75) and ADG as independent variable. Mitochondria complex I (mitochondrial NADH:ubiquinone oxidoreductase) is one ...
A study of the treatment of the intestinal parasites of swine
(University of Missouri--Columbia, 1914)
Parasitic infestation of the intestines is one of the most serious and wide spread diseases of swine. With the exception of cholera there is probably no other one disease causing greater loss to hog owners. Parasitism, ...
Biomarker assessment for detection of joint pathology in horses and evaluation of the nutritional supplement Steadfast equine as a therapeutic
(University of Missouri--Columbia, 2012)
Degenerative joint disease (DJD) is one of the most prevalent musculoskeletal disorders seen in horses, resulting in loss of performance ability, early retirement and significant cost to horse owners. Biomarkers of tissue ...
The influence of breeding young swine upon the parents, the offspring and the breed
(University of Missouri--Columbia, 1913)
There is no animal contributing directly to the food supply of the people which is at the same time so generaly kept and so little understood as the pig. Nor is there one which, intimately associated as it is with their ...
Function and gene expression of circulating neutrophils in dairy cows : impact of micronutrient supplementation
(University of Missouri--Columbia, 2012)
Three experiments were conducted to investigate the mechanisms of neutrophil dysfunction during the periparturient period and test potential nutritional strategies to prevent the immune-alteration typical of this time. The ...
Cattle production : the cost in Missouri of producing a steer ready for the feed lot
(University of Missouri--Columbia, 1906)
If one desires to know the cost of making a locomotive he would not think of going to anyone other than a locomotive manufacturer. If one wishes to know the cost of constructing a building he goes to a contractor. Desiring ...
Comparison of long-term CIDR-based protocols to synchronize estrus in postpartum beef cows
(University of Missouri--Columbia, 2011)
Estrus synchronization and artificial insemination are two of the most important management practices available to producers to increase reproductive performance in a beef cow-calf operation. Unfortunately, a small number ...
Age as a factor in animal breeding
(University of Missouri--Columbia, 1918)
The experiment furnishing the basis for this discussion was begun in 1909 by Director F.B. Mumford and has since been continued under his general direction. Swine were used in the experiment since they probably lend ...
Tissue inhibitor of metalloproteinase-1 contributes to ovulatory dysfunction in a rat model of endometriosis
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Endometriosis causes ovarian dysfunction, but the mechanisms are unknown. These experiments utilize a rat model of surgically-induced endometriosis ...
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 ...
