(University of Missouri--Columbia, 2021)
= 267 [plus or minus] 2.6 kg) were obtained from 3 different sources and assigned risk groups based on distance traveled, previous health management, and incidence of disease. Pen fed EO tended (P = 0.09) to have a greater DMI than control. After 56 days...
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)
to determine if birds benefit from periods of warmer and cooler environmental temperatures during different parts of the day (Waibel and Macleod, 1994). One management strategy that has not been researched in poultry, but has been studied in the swine model...
Effect of high peroxide value fats on performance of broilers in normal and immune challenged states
(University of Missouri--Columbia, 2009)
A series of trials were conducted in order to determine the effects of high peroxide value fats on performance of broilers in normal and immune challenged states from 0-49 days of age. In the first experiment, birds were fed one of six diets...
The effects of supplemental anionic salts & yeast culture on the production of dairy cattle during the periparturient period
(University of Missouri--Columbia, 2006)
lactation. Two independent research trials were conducted to evaluate the effect of a sulfur-based anionic salt fed during late gestation and yeast culture fed during the periparturient period on mineral and energy metabolism, intake, health, and production...
Effects of Artemisia afra and Artemisia absinthium on fertility of male mice exposed to increased ambient temperatures for 24 hours
(University of Missouri--Columbia, 2010)
Males exposed to elevated temperatures display a decrease in reproductive performance resulting in decreased profit for producers. The use of herbs to alleviate the effects of heat in tropical countries has been documented ...
Heritable, differential gene expression in pre-implantation embryos from rats with endometriosis and their daughters
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Endometriosis, which affects millions of women, is a condition where the uterine lining grows outside of the uterus and is associated with subfertility ...
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 differences in microbiome...
Approaches for alleviating toxic effects of aflatoxin in lactating dairy cows and weanling pigs
(University of Missouri--Columbia, 2010)
aflatoxin M1 (AFM1) into milk. Aflatoxin M1 is toxic and carcinogenic, and is of great concern with respect to human health because of the high consumption of milk and milk products by humans, especially children. Due to the involvement of AF in disease...
Estrus induction and maintenance of cycles in gilts with PG-600 and boar exposure
(University of Missouri--Columbia, 2007)
This study looked at the efficacy of PG-600 and boar exposure to induce and maintain cycles. Gilts received one of four treatments: PG-600, weekday 10 min full physical contact boar exposure (BE), PG-600+BE, and neither ...
Determination of fat percentage using three different methods within marbling scores on beef longissimus muscle
(University of Missouri--Columbia, 2010)
analysis procedures. Steaks (n = 119) were selected by USDA grading system using an E + V Vision Grading camera at a commercial beef plant during one day. Samples were taken at the 13th rib from both sides of the carcass and aged for 14 d. The right side...
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 oil on the performance...
Role of preovulatory estradiol in uterine and luteal function
(University of Missouri--Columbia, 2018)
in estrus (Richardson et al., 2016). We hypothesized that increased preovulatory concentrations of estradiol would enhance conceptus elongation in beef heifers. To test the preceding hypothesis conceptus elongation on day 16 (day 0 = GnRH-induced ovulation...
Investigation of mechanisms associated with establishment and maintenance of pregnancy in beef cattle
(University of Missouri--Columbia, 2020)
decrease pregnancy loss in postpartum beef cows. The 7-day CO-Synch + CIDR(R) protocol was used to synchronize estrus/ovulation in 326 cows. The protocol included administration of GnRH (GnRH1) on day -9, treatment with exogenous progesterone via a CIDR...
Developmental exposure to bisphenol a (BPA) and ethinyl estradiol (EE) and effects on F1 parental care and F2 pup parameters in California mice (Peromyscus californicus)
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Environmental exposure during the perinatal period can promote health and disease in offspring, otherwise coined developmental origins of health and disease (DOHaD). Endocrine...
Evaluation of the efficacy of high levels of microbial phytase in broilers
(University of Missouri--Columbia, 2006)
(hatch to 21 days), high levels of dietary phytase improved BWG above the NRC and positive control diets (EXP 1 and 3). However, as broilers reached market weight there were no differences (P [greater than] 0.05) in BWG. Results of this research indicate...
Influence of subclinical hypocalcemia on plasma biochemical parameters, liver histologic changes, and common postpartum diseases in dairy cows
(University of Missouri--Columbia, 2011)
Holstein cows were assigned to one of two groups 1) normocalcemic (n=49; ionized calcium [iCa] ! 1.0 mmol/L) or 2) hypocalcemic (n=51; [iCa] [less than 1.0 mmol/L) based on whole blood [iCa] on the day of calving. Blood samples were collected from all cows...
Efforts to identify large offspring syndrome during pregnancy through ultrasonography and maternal blood transcriptome analyses
(University of Missouri--Columbia, 2021)
