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)
in the year 2016 (USDA, 2017a,b). The production of broilers in the United States has increased by 1% from 2015 and turkey production is up 5% from 2015 (USDA, 2017a). One could speculate that these production values will continue to increase...
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 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 ...
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...
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...
Implications of ovarian and uterine maturity evaluated in replacement heifer candidates
(University of Missouri--Columbia, 2021)
days after the end of the breeding season. The incidence of disparate ovarian score (OS) and uterine score (US) was 33.7 percent (n = 158/469) in Experiment 1 and 16.3 percent (n = 3,622/22,174) in Experiment 2. Heifers assigned a RTS of less than 3-3...
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 ...
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 ...
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...
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, ...
