Early embryonic loss is a significant factor in livestock species' infertility, resulting in an economic deficit. In cattle, the in vivo fertilization rate is ~90%, with an average calving rate of about 55%, indicating an embryonic-fetal mortality rate of roughly 35%. Further, 70-80% of total embryonic loss in cattle occurs during the first three weeks after insemination, particularly between days 7-16. Growing evidence indicates that the oocyte plays an active role in regulating critical aspects of the reproductive process required for successful fertilization, embryo development, and pregnancy. However, defining oocyte quality remains enigmatic. Recently, many have abandoned the notion that …
Potentials Of Pleurotus: Reimagining The Relationship Between Cattle And Brewer's Spent Grain, Zoe Stojkovic
Potentials Of Pleurotus: Reimagining The Relationship Between Cattle And Brewer's Spent Grain, Zoe Stojkovic
Senior Projects Spring 2023
Brewer’s spent grains (BSGs), a byproduct from beer production, are generated in excess globally. Most often, they are sold or given to proximate cattle farmers for use as feed. However, spent grain can also be used as a medium for fungal cultivation. Given that certain fungal species have the capability to degrade lignin and produce protein, the cultivation of fungi on spent grains may serve to enhance the nutritional profile of the grains for their use as cattle feed. This project is an effort to determine the compatibility of fungal cultivation with BSGs in order to both improve upon cattle …

Exploring The Biological Basis Of Residual Feed Intake In Beef Cattle Using Multi-Omics Analysis., Godstime Ayobami Taiwo
Graduate Theses, Dissertations, and Problem Reports
Efficient feed utilization is critical for both economic sustainability and environmental responsibility in modern livestock production. While there has been extensive research, the multifaceted nature of feed efficiency remains complex, with many biological factors still unexplored. This dissertation examines the physiological foundations of feed efficiency by elucidating some of the complex biological mechanisms associated with residual feed intake (RFI) phenotype in beef cattle, using a range of Omics approaches. We hypothesized that metabolites related to amino acids, carbohydrates, and fatty acids could act as potential biomarkers for RFI. Through a chemical group-based metabolomics method, we identified enriched pathways in feed-efficient …
The Prevalence And Impact Of Dairy/Beef Crosses On Cattle Producers In New Hampshire, Eleanor J. Braun
The Prevalence And Impact Of Dairy/Beef Crosses On Cattle Producers In New Hampshire, Eleanor J. Braun
Honors Theses and Capstones
Recent years had seen a significant rise in the use of beef semen on dairy cows in the United States. This trend was not widely understood, especially as it related to dairy farmers in New Hampshire. A survey was sent out by mail to the ninety-seven dairy farms in New Hampshire. There were thirty-seven responses to the survey. Thirty-two out of thirty-seven respondents bred beef semen to their dairy cows. Twenty-one of these respondents raised dairy x beef on their farms and twenty-six planned to continue breeding dairy x beef. The most common breeds used in dairy x beef crosses …
