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...
Comparison of long-term progestin-based protocols to synchronize estrus in beef heifers
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Experiment 1 evaluated two long-term progestin-based and controlled internal drug release estrus synchronization protocols to determine their potential ...
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...
Effects of conjugated linoleic acid on tissue lipid composition and bone remodeling in an ovariectomized aged rat model
(University of Missouri--Columbia, 2012)
not be enough CLA for this enhanced anti-inflammatory response. In conclusion, the geriatric postmenopausal model that we created may be beneficial in future osteoporosis research....
Phenotypic and genetic effects of disposition on beef tenderness and quality attributes
(University of Missouri--Columbia, 2011)
Cattle temperament (exit velocity; EV) and steak tenderness (Warner-Bratzler shear force) have been shown to be associated in Bos indicus cattle (Behrends et al., 2009). Both traits potentially provide opportunities for improvement among beef herds...
Effects of low crude protein diets with amino acid supplementation on broiler performance in the starter period
(University of Missouri--Columbia, 2009)
A series of experiments were conducted to examine the effects of feeding low crude protein (CP) corn and soybean meal diets with crystalline amino acid supplementation to broilers from 0-3 weeks of age. It was hypothesized ...
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...
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 ...
Effects of heat stress and fescue toxicosis on the immune system and other physiological parameters
(University of Missouri--Columbia, 2010)
. This research identified adaptive responses to fescue toxicosis that highlighted shifts in immune function....
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 ...
Comparative transcriptional profiling of the uterus according to stage of the estrous cycle and pregnancy status in gilts
(University of Missouri--Columbia, 2007)
of temporal and spatial specific gene expression, help create the microenvironment required for movement of gametes, capacitation of sperm, fertilization, successful embryonic development and subsequent fetal growth. During the first 30 days of gestation...
Effects of heat stress on reproduction and productivity of primiparous sows and their piglets' performance
(University of Missouri--Columbia, 2009)
Heat stress (HS) produces seasonal infertility in sows and decreases reproductive efficiency. Sows were exposed to HS during a production cycle (gestation [gest], lactation [lact], and breeding) to examine productivity. ...
Influence of diet, production traits, blood hormones and metabolites, and mitochondrial complex protein concentrations on residual feed intake in beef cattle
(University of Missouri--Columbia, 2009)
Residual feed intake (RFI) is the difference between measured feed intake and predicted feed intake of an animal. Intake prediction is computed from a regression of intake on gain and metabolic body weight. Residual feed ...
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...
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, milk production...
Differential gene and protein expression in pig nuclear transfer extraembryonic membranes and blastocyst stage embryos
(University of Missouri--Columbia, 2010)
