Effects Of Weaning Age And Winter Development Environment On Heifer Grazing Distribution, N.L. Hojer, M.B. Hubert, P.S. Johnson, M.H. Price

South Dakota Beef Report, 2012

The objective of this experiment was to determine if early weaning (approximately 125 d) vs. normal weaning (approximately 250 d) and wintering replacement heifers in drylot versus rangeland affected heifer grazing distribution during the subsequent summer. Heifer calves from the 2009 and 2010 calf crop (n = 104 and 73, respectively) were allocated to the 2 weaning treatments and then stratified by age into the 2 winter development treatments. During the summer of yr 1 heifers were allocated to 2 pastures by winter treatment, and in yr 2, all 4 treatment combinations were allocated to separate pastures. A subset of …

Influence Of Propionate Salt Levels On Young Cow Reproductive Performance, J.A. Walker, G.A. Perry, K.C. Olson

South Dakota Beef Report, 2012

A supplementation study was conducted to evaluate level of propionate salt (Ca-propionate) on young cow performance over two years. One hundred-twenty cows were allocated to one of three treatments at calving. Propionate salt was incorporated in a protein supplement at a rate of 0, 80 or 160 g/d. Cows were individually supplemented twice weekly at 2 lbs/d. In year 1, cows had access to pasture and hay. In year 2, cows had access to a native range pasture. Blood was collected weekly and analyzed for progesterone (P4) to determine postpartum interval (≥1 ng P4/ml). Weights and body condition scores (BCS) …

Follicle-Stimulating Hormone Is Independently Associated With Lean Mass But Not Bmd In Younger Postmenopausal Women, Margaret L Gourlay, Bonny Specker, Chenxi Li, Catherine A. Hammett-Stabler, Jordan B. Renner, Janet E Rubin

Ethel Austin Martin Program Publications

PURPOSE: Increased follicle-stimulating hormone (FSH) has been associated with lower bone mineral density (BMD) in animal models and longitudinal studies of women, but a direct effect has not been demonstrated.
METHODS: We tested associations between FSH, non-bone body composition measures and BMD in 94 younger (aged 50 to 64 years) postmenopausal women without current use of hormone therapy, adjusting for sex hormone concentrations and clinical risk factors for osteoporosis. Lean mass, fat mass and areal BMD (aBMD) at the spine, femoral neck and total hip were measured using dual energy X-ray absorptiometry (DXA). Volumetric BMD (vBMD) was measured at the …

Effects Of Lean Beef Supplementation On Iron Status, Body Composition And Performance Of Collegiate Distance Runners, Danielle E. Burke, Jocelyn V. Johnson, Matthew D. Vukovich, Kendra K. Kattelmann 6884045

Health and Nutritional Sciences Faculty Publications

Iron deficiency is prevalent among endurance athletes, particularly females. Low iron may compromise oxygen delivery and physical performance. Vegetarianism, desire for convenience, and perceived health risks associated with red meat contribute to low bioavailable iron intakes. The purpose of this study was to examine if lean beef supplementation would maintain iron status, improve body composition and increase performance of distance runners after 8 weeks. Twenty-eight (14 female) Division-I cross-country runners were stratified by iron status, use of iron supplements, and gender, and randomized into a control (n = 14) and intervention group. All participants maintained their typical diet and consumed …

Translation Of Vibration From A Vibrational Plate To The Human Body, Lars Mattison

The Journal of Undergraduate Research

This study was done to validate the results of our previous study [1] as well as analyze how the Soloflex Whole Body Vibration Platform translates vibration to the human body. The purpose of causing vibration within the human body is to increase bone density, possibly by activating osteoblasts within the bone. When the body is subjected to stress, it adapts as quickly as possible to counteract this stress. There is evidence that vibration caused by low magnitude mechanical signals (LMMS) increases bone in children with disabling conditions [2] and young women (15-20 years) with low bone mineral density [3]. Our …

Antimicrobial Activity, Cytotoxicity And Phytochemical Analyses Of Rhus Aromatica, Rhus Glabra And Sanguinaria Canadensis Native To South Dakota, Gitanjali Nandakafle

Electronic Theses and Dissertations

A total of twenty five South Dakota native medicinal plants were screened against enterotoxigenic Escherichia coli using a disk diffusion assay. Out of these 25 plants, three plants Rhus aromatica, Rhus glabra and Sanguinaria canadensis demonstrated the highest bacterial inhibition. The minimum inhibitory concentrations (MIC) of these plant extracts were determined using a bacterial enumeration assay. Alamar Blue in vitro cytotoxicity test showed that all extracts have some toxic effect to porcine intestinal epithelial cell lines. Phytochemical analysis of these plant extracts indicated the presence high concentration of flavonoids and condensed tannins in R. aromatica and that R. glabra contained …

Maternal Nutrition During Mid-Gestation Influences Gene Expression Essential For Intramuscular Adipose Tissue And Muscle Development In Bovine Fetuses, Tracy D. Jennings

Electronic Theses and Dissertations

Given the potential variation in forage quantity and quality available to gestating cows, it is possible to encounter periods of nutrient restriction, while supplementation decisions could lead to periods of over-nutrition. Maternal nutrition during mid-late gestation has shown to influence adipose development and myogenesis in the fetuses of various species; however, bovine research is limited. The objective of this experiment was to determine whether maternal nutrition during mid-gestation alters genetic expression of fetal adipogenic and myogenic regulatory factors, resulting in differences in adipose development and muscle characteristics of the bovine fetus. Twenty-two bred Angus crossbred heifers (BW = 527.73 ± …

Great Plains Soils May Be C Sinks, David E. Clay, Gregg C. Carlson, Sharon A. Clay, James Stone, Kurtis Reitsma, Ronald Gelderman

Agronomy, Horticulture and Plant Science Faculty Publications

Numerous studies with wide-ranging results have been conducted to resolve if Great Plains soils are a C source or sink. The authors addressed the source/sink question by examining the results from producer soil samples and production surveys that were analyzed and archived by the South Dakota Soil Testing Laboratory. Results showed that between 1985 and 2010, soil organic C content increased at a rate of 326 lb C/A/year, for a total increase of 24%. The increase was attributed to planting better adapted varieties and using better management practices that on average increased corn grain yields 2.29 bu/A/year. Higher soil organic …

Birth Timing For Mountain Lions (Puma Concolor); Testing The Prey Availability Hypothesis, Brian D. Jansen

Natural Resource Management Faculty Publications

We investigated potential advantages in birth timing for mountain lion (Puma concolor) cubs. We examined cub body mass, survival, and age of natal dispersal in relation to specific timing of birth. We also investigated the role of maternal age relative to timing of births. We captured mountain lion cubs while in the natal den to determine birth date, which allowed for precise estimates of the population birth pulse and age of natal dispersal. A birth pulse occurred during June–August. Body mass of cubs was related to litter size and timing of birth; heaviest cubs occurred in litters of 2, and …

Initial Observations On The Inclusion Of High Protein Distillers Dried Grain Into Rainbow Trout Diets, Michael E. Barnes, Michael L. Brown, Kurt A. Rosentrater

Natural Resource Management Faculty Publications

An initial investigation into the inclusion of high protein distillers dried grain with solubles (HPDDG) in juvenile rainbow trout Oncorhynchus mykiss diets was conducted during a 36-day feeding trial. Four experimental diets containing either 10% or 20% HPDDG with supplemental amino acids, and either with or without phytase, were compared to a fish-meal-based, non-HPDDG, diet. There was no significant difference among any of the diets in total weight gain, percent weight gain, feed conversion ratio, or percent mortality. There was also no significant difference in length, weight, condition factor, hepatosomatic index, viscerosomatic index, or any fish health parameter in fishes …

An Initial Investigation Replacing Fish Meal With A Commercial Fermented Soybean Meal Product In The Diets Of Juvenile Rainbow Trout, Michael E. Barnes, Michael L. Brown, Kurt A. Rosen, Jason R. Sewell

Natural Resource Management Faculty Publications

The inclusion of PepSoyGen (PSG), a commercially-available fermented soybean meal product, was evaluated with juvenile rainbow trout, Oncorhynchus mykiss in an initial 70-day feeding trial, with a supplemental trial involving a subset of the experimental diets continuing for an additional 40 d. Six diets containing 0%, 10%, 20%, 30%, 40%, or 50% PSG, with the PSG directly replacing fish meal, were used in the first trial. There were no significant differences in weight gain or feed conversion ratio between the fish meal-based control diet and diets containing up to 30% PSG. However, weight gain was significantly reduced and feed conversion …

Juvenile Rainbow Trout Responses To Diets Containing Distillers Dried Grain With Solubles, Phytase, And Amino Acid Supplements, Michael E. Barnes, Michael L. Brown, Kurt A. Rosentrater

Natural Resource Management Faculty Publications

Distillers dried grain with solubles (DDGS) was evaluated in juvenile Shasta-strain rainbow trout Oncorhynchus mykiss diets during a 36-day feeding trial. Two experimental diets containing either 10% or 20% DDGS with supplemented amino acids (lysine, methionine, isoleucine, and histidine) and phytase were compared to a fish meal-only control diet. Tanks of trout receiving diets containing either concentration of DDGS weighed significantly less at the end of the trial and had significantly poorer feed conversion ratios than tanks of fish being fed the fish mealonly control. There was no significant difference in individual fish length, weight, condition factor, or any fish …
