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...
Silage as a part ration for horses and mules or various ages under varying conditions
(University of Missouri--Columbia, 1916)
Text from page 174: This was an initial effort to feed silage as a part ration to horses and mules of various ages and under varying conditions at the Missouri Experiment Station. The data in the 1915-1916 tests are not sufficient to make possible...
The effect of reduced nocturnal temperatures on the performance of broiler chicks and hen turkey poults from 0 to 21 days of age
(University of Missouri--Columbia, 2018)
"The world population has increased over the past century and with this increase in the world population comes an increase in demand of animal protein for consumption. The United States produced 8.78 billion broilers and ...
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 ...
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...
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...
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. ...
Exploration of fecal microbial transfer and the competitive exclusion concept in broilers as a possible alternative to antibiotic growth promoters
(University of Missouri--Columbia, 2021)
Four studies were conducted to explore the effects of early life Fecal Microbiota Transfer (FMT) from healthy feed efficient finished broilers into day-old broiler chicks on growth performance indices, changes and or ...
Effects of continous administration of low-dose of Escherichia coli lipopolysaccharide in chicks and poults fed non toxic doses of aflatoxin B1 and T-2 toxin
(University of Missouri--Columbia, 2005)
Six studies (three with broilers and three with turkeys) were conducted to determine if E. coli lipopolysaccharide (LPS) would enhance the effects of aflatoxin B1 (AFB1) and the T-2 toxin (T-2) in chicks and poults fed ...
Evaluating pig performance, carcass merit and processed pork quality when chestnuts and acorns are fed to Duroc-influenced pig genetics during late finishing
(University of Missouri--Columbia, 2019)
The objective of this study was to determine effects of feeding chestnuts and acorns on growth performance, carcass quality and further processed products of Duroc/Duroc crossbred finishing barrows. Barrows (n = 30) were ...
Uterine regulation of preimplantation embryo development in fertility-classified heifers
(University of Missouri--Columbia, 2018)
, serial embryo transfer (3-4 rounds) was used to classify heifers based on pregnancy success on day 28 as high fertile (HF; 100%), subfertile (SF; 25%), or infertile (IF; 0%). Next, a series of experiments were conducted using the fertility...
Applications of ancestry estimation in cattle population genetics
(University of Missouri--Columbia, 2019)
Accounting for ancestry and cryptic population structure is important in population genetic data analysis. The estimation of ancestry can help elucidate the effects of admixture or stratification on allele and genotype ...
The relation of type and conformation to production in dairy cattle
(University of Missouri--Columbia, 1916)
Text from introduction: "The object of this investigation is to determine so far as possible how much importance should be attached to form and type in the selection of dairy cows and to what extent type may be expressed ...
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, ...
