The ability of a cow to become pregnant and a calf to thrive after birth are crucial to successful dairy farm operations. Recent evidence in humans has shown bacteria in the reproductive tract can influence maternal fertility and the bacterial community of newborns, an indicator of early health. This same relationship might exist in dairy cattle. I propose that specific traits related to fertility and the bacterial community in the reproductive tract of dairy cattle influences their ability to become pregnant and influences the bacterial community developing in calves after their birth. In my first experiment, I collected samples of uterine fluid from cattle that had never been pregnant before the first time they would be bred. I also collected blood samples before and after breeding to measure hormone levels as well as measurements of portions of reproductive tract using an ultrasound. Using a specific portion of DNA that is similar across all bacteria, I identified the bacterial community in the collected uterine fluid. Cattle were grouped based on breeding outcome (not pregnant, pregnant but lost, or kept pregnancy) and season of breeding. Differences in various traits and bacterial communities were examined based on breeding outcome and season. I found that traits like hormone levels in the blood and size of structures on the reproductive tract, and uterine bacterial community all differed based on breeding outcome. We also found that uterine bacterial community also differed based on season of breeding. These results could be used to predict if a cow will become pregnant before they are ever bred, but more research is needed. In our second experiment, we collected samples from the reproductive tract, milk, mouth, and feces of cows immediately after they gave birth. We then collected samples from their calves right at birth as well as at various time points during their early life. Using the same section of DNA used during the first experiment, we identified the bacterial community composition from the various maternal and calf samples. We then identified correlations between maternal and calf bacteria and used a mathematical model to see if the maternal bacteria could predict bacteria in the calf. We found that the various maternal bacteria could predict calf bacteria throughout the calves early life. While an experiment using a larger group of cows and calves is needed, our results indicate that the maternal bacteria could be used to predict calf bacteria and may help determine which calves are more likely to become sick than others. Overall, we found that the bacteria in the reproductive tract could be used to predict ability to become pregnant and calf bacterial development. The incorporation of this bacterial community as a trait on farms could help reduce pregnancy loss and calf illness, but further research examining how the bacteria interact with the animal is needed.

Повний текст джерелаStuart Heisler is an American director working in the context of major studios based on a division into genres and on actors constituting models for spectators and used to attract crowds in the period from the 1930s to the 1960s. Films by Stuart Heisler will be studied in detail through film analysis, in a stylistic approach of the filmmaker’s career, but also in relation to the global meaning of the films in relation to their narrative, the acting and their use of sets. The relationship between this aesthetic and the films’ modes of production of the can be considered as a direct consequence of Hollywood’s modes of production. So, how to characterize these joint evolutions? They concern both the filmmaker and his production context through time in a historiographical perspective. The study will combine a stylistic and a historiographic approach of Stuart Heisler’s career. Characterizing these evolutions will make it possible to understand the different facets of the director's practice, his manner of cinematographic creation for each film, and finally to make the artistic portrait of the director through his practice within the production system in which he is working. The study will paint the artistic portrait of Stuart Heisler through his insertion in several contexts of production corresponding to the joint evolution of the filmmaker’s career and his production structures. It will define the forms and the modalities of the particular aesthetic coalescence of the director's style, starting from his position as editor during the 1920’s and 1930’s during his career beginnings before the actual directing. The influence of the different collaborators have on Stuart Heisler will be studied before the passage from editing to directing in 1936. Heisler goes towards more independence in 1944 and 1945 whereas his personal will remains framed by the production. Stuart Heisler goes to the situation of a director developing a particular style during the 1940s and 1950s centered around the filmic figure. The central figure of the fire is founded on the destruction of the pro-filmic. The figure of the fire is also related to the figure of bursting and is visible for television production during the 1950s and 1960s. The director is turning towards television in the 1950’s and 1960’s. The filmmaker's familiarity with his work is reflected in the television series. The work will finally study the works inspired by Stuart Heisler's style
