The effect of a supplemental trace mineral injection on developing beef bull and heifer reproductionKirchhoff, Alissa A. January 1900 (has links)
Master of Science / Department of Animal Sciences and Industry / Karol E. Fike / Trace mineral supplementation is necessary for proper reproductive success. Little research has evaluated the effect of an injectable trace mineral product, in conjunction with a dietary mineral supplementation program, on reproduction. This thesis includes two separate studies evaluating the use of an injectable trace mineral product, in addition to a dietary mineral program, on the reproductive success of yearling bulls and heifers. In the first study, we hypothesized that when dietary trace mineral needs are met, administration of an injectable trace mineral product to developing beef bulls would cause a short-term increase in circulating trace mineral concentrations, but not alter semen quality nor ability to pass a breeding soundness examination. Trace mineral treatment did not affect scrotal circumferences and BW of bulls throughout the trial (P [equal to or greater than] 0.20). Trace Mineral bulls had greater (P [equal to or less than] 0.0001) trace mineral concentrations at 8 h post-treatment than Control bulls. Semen trace mineral concentrations on d 42 and 91 were similar (P [equal to or greater than] 0.52) between treatments. Sperm parameters improved (P [equal to or less than] 0.003) from d 42 to 91, but did not differ (P [equal to or greater than] 0.06) between treatments. A similar (P = 0.94) percentage of Trace Mineral (67%) and Control (68%) bulls passed a BSE 91 d post-treatment. In the present study, supplemental trace mineral injection was successful at raising circulating trace mineral levels, but did not alter semen trace mineral levels nor improve semen quality. In the second study we hypothesized that when dietary trace mineral needs are met, the use of an injectable trace mineral product in developing heifers would not affect pregnancy rates at single service fixed-time artificial insemination (FTAI). Trace Mineral heifers had greater (P = 0.02) pregnancy rates (51.28%) than Control heifers (25.58%). The percentage of Trace Mineral (30.77%) and Control heifers (47.50%) that displayed estrous behavior prior to FTAI as indicated by a red estrous detection patch was not different (P = 0.13) between treatments. In the present study, despite dietary trace mineral requirements being met, use of an injectable trace mineral injection improved pregnancy rates following FTAI, but did not affect estrous behavior.

Efeito da condição sexual sobre o desempenho, características de carcaça e qualidade de carne de Bos indicus (Nelore) confinados / Effect of gender on performance, carcass traits and meat quality of feedlot finished Bos indicus (Nellore) cattleJuan Fernando Morales Gómez 29 August 2016 (has links)
Este trabalho foi conduzido para avaliar o efeito da condição sexual sobre o desempenho, concentração de testosterona, características de carcaça e qualidade da carne de bovinos Nelore confinados. Cinquenta e oito machos bovinos (430 ± 36 kg; 24 meses de idade), foram divididos em três grupos em um delineamento inteiramente casualizado. Foi realizado, em 15 animais, o procedimento de castração cirúrgica (CC), aos 12 meses de idade, enquanto que 21 animais receberam duas doses da vacina de imunocastração (IC), dentro de um intervalo de 30 dias, e 22 animais permaneceram não-castrados (NC). Os animais foram alocados em baias individuais e alimentados com uma dieta contendo 70% concentrado e 30% volumoso durante noventa dias precedidos por um período de adaptação de vinte e um dias. Foi avaliado o desempenho e características de carcaça a cada 28 dias. Os animais foram abatidos e foi avaliada a qualidade da carne. Animais NC apresentaram maior ganho de peso, eficiência alimentar, peso de carcaça quente e rendimento de carcaça comparado com animais CC e IC (P<0.05). Animais castrados apresentaram maiores valores de cor L*, a*, b* e perda por cocção que animais NC (P<0.05). A imunocastração diminuiu o desempenho dos animais, comparado com animais CC ou NC. Porém, é uma alternativa à castração cirúrgica pois possui as mesmas características de carcaça e qualidade da carne. A imunocastração melhora a cor da carne e diminui a frequência de carnes DFD comparado com animais NC. / This study was carried out to evaluate the effect of the sexual condition on performance, testosterone concentration, carcass traits and meat quality of feedlot Nellore cattle. Fifty-eight males (430 ± 36 kg BW; 24 mo old) were divided into three groups in a randomized complete design. Surgical castration (SC) procedure was performed in 15 animals at 12 months old, whereas 21 animals received two doses of immunocastration vaccine (IM), within an interval of 30 days. In addition, 22 animals remained intact (NC). The animals were allotted in individual pens and daily fed a diet containing 70% concentrate and 30% roughage during ninety days preceded by an adaptation period of twenty one days. Performance and carcass characteristics were evaluated every 28 days. The animals were slaughtered and the meat quality was evaluated. The NC animals showed greater average daily gain, feed efficiency, hot carcass weight and carcass yield compared with SC animals and IM (P <0.05). Castrated animals had higher color values L *, a *, b * and cooking loss that NC animals (P <0.05). Immunocastration decreased performance when compared to SC or NC animals. However, it is an alternative tool to surgical castration because it has the same carcass characteristics and meat quality. Immunocastration improves the color of the meat and reduces the frequency of DFD meat compared to NC animals.

Diagnosis of Tritrichomonas foetus in bulls by culture and PCR methodsIrons, Pete Charles 29 March 2005 (has links)
The aim of this work was to examine the effects of sampling method on accuracy of culture for Tritrichomonas foetus; and the effects of sampling method, time delay, and addition of a DNA preservative on the accuracy of a PCR test. Samples from two different sources were used for Experiment 1. Preputial scrapings were collected from one group of three infected and one uninfected bull 10 times. Secondly, samples were collected from 5 infected bulls by both sheath washing and scraping on 6 occasions, while 8 uninfected animals were sampled three or more times. Twenty nine out of 30 samples from the first sample set were found to be positive, and 83 % of samples collected by both methods for the second sample set tested positive. No samples from the control bulls were found to be positive. Scraping was found to offer significant practical advantages over washing. It may be subject to greater operator variability than sheath washing. The second experiment utilised the same samples as were used for the second data set under Experiment 1. Guanidinium thiocyanate (GuSCN) was added to half of each sample. Each sample was cultured, while all samples were subjected to DNA extraction within 6 and 30 hours and after 5 days of storage at 4 °C. PCR and agarose gel electrophoresis was performed. No samples from the control animals tested positive on PCR. The sensitivity of the PCR on samples from infected bulls ranged from 0,9 in samples extracted within 6 hours to 0,31 in samples extracted after 5 days. Sampling method had no effect with the exception of samples held for 5 days with GuSCN, where sheath washing was superior to scraping. The addition of GuSCN had no effect. Holding time reduced sensitivity at 5 days, but the effect was not significant at 30 hours. It is concluded that preputial scraping is equal in sensitivity to washing for culture of Tritrichomonas foetus. Preputial samples for PCR testing should be submitted as soon as possible after collection, and the addition of GuSCN has no effect. Samples collected by sheath washing may be superior to those collected by scraping for PCR testing. The requirement for a test with sufficient sensitivity to allow reliable identification of infected bulls based on one sample has not been met with the described method. / Dissertation (MMedVet (Gyn))--University of Pretoria, 2002. / Production Animal Studies / unrestricted

Mammals of the Bull RunThatcher, Edward M. 01 January 1976 (has links)
This study of mammals of the Bull Run Planning Unit has a dual character. First, mammals of special scientific or natural history interest such as threatened or endangered species were sought. This was in conjunction with a Mt. Hood Bull Run Planning Unit. Second, a zoogeographical study of mammals of the Bull Run was performed. Abundance and distributional data was recorded for each species observed. This data was related to availability to moisture as indicated by plant associations trapped. Difference in habitat utilization along a moisture gradient was investigated as a possible coexistence mechanism for sympatric small mammals in the Bull Run Planning Unit.

Red Bull, mer än bara ett varumärke : En kvantitativ enkätstudie av konsumenters inställningar till varumärket Red BullBråtman, Martin, Grötting, Linus January 2022 (has links)
Den österrikiske entreprenören Dietrich Mateschitz grundade 1983 Red Bull tillsammans med thailändska investeraren Chaleo Yoovidhya. 38 år senare sålde Red Bull uppskattningsvis 9,8 miljarder burkar årligen. Dietrich Mateschitz lanserade 1983 inte bara en ny produktkategori utan ett marknadsföringskoncept som idag kan återfinnas inom sport, musik och kultursammanhang. I denna uppsats utforskas 18–32 åriga svenskars relation till Red Bull, både varumärket som energidrycken i ambitionen att expandera och belysa den typ av marknadsföring och varumärkesarbete som företaget genomför. Detta sker genom en kvantitativ enkätundersökning med frågor inspirerade av Lynn B.Upshaws Building Brand Identity, A strategy for success in a hostile marketplace och Lena Leikas i Nordiska ministerrådets Otraditionella marknadsföringsmetoder mot barn och unga. Redovisning av resultatet och analys följer. Totalt 153 svar samlades, varav 152 av dem tillfrågade var bekanta med varumärket i fråga. Enkäten belyste åsiktsskillnader och starka känslor de tillfrågade kände kring varumärket, övervägande majoriteten positiva men också en avsevärt stor proportion negativa. Enkäten visade en åsiktsskillnad mellan varumärket och produkten med motivationer grundade i produktens natur.

Factors influencing spawning migration of bull trout (Salvelinus confluentus) in the North Fork Skokomish River, Olympic National Park, WashingtonBrenkman, Samuel J. 26 February 1998 (has links)
Distribution and life history characteristics of lacustrine-adfluvial bull trout (Salvelinus
confluentus) were described in the North Fork Skokomish River Basin (including Lake
Cushman, a reservoir) from 1994 to 1996. Day snorkeling was conducted in the river to
determine initiation of the bull trout spawning migration, abundance of spawners, and
duration of spawning. Declining photoperiod, increased river discharge, and decreased
water temperature appeared to influence timing of migration and spawning. Lacustrine-adfluvial
bull trout typically entered the North Fork Skokomish River in October although
some fish entered as early as May. Mean lengths of spawners consistently increased from
June to December 1996, and early migrating bull trout were shorter than those fish that
entered after river discharge increased in October. The presence of two phases of the
spawning migration may be indicative of two populations spawning in the river. Bull trout
spawned between mid-September and December in the river and tributaries after water
temperatures declined. All spawning occurred at temperatures less than 7.5��C.
Comparisons with studies of other lacustrine-adfiuvial bull trout populations that inhabit
river and reservoir complexes suggested that bull trout exhibit specific migratory strategies
related to local environmental conditions. In the North Fork Skokomish River, changes in
abundance of bull trout, mountain whitefish (Prosopium wilhamsom), cutthroat trout
(Oncorhynchus dark), and rainbow trout (Oncorhynchus mykiss) revealed distinct
temporal segregation among these species. Olympic National Park, a designated
Biosphere Reserve, contains one of the largest remaining areas of relatively pristine habitat
in the range of bull trout. Knowledge of responses of bull trout to changes in river
discharge and temperature from relatively undisturbed systems, such as the North Fork
Skokomish River, may be useful in understanding patterns observed in degraded
environments. / Graduation date: 1998
