Feeding The Future Meat Doesn’T Come Cheap, Lukas C. Southard Dec 2019

Feeding The Future Meat Doesn’T Come Cheap, Lukas C. Southard

Capstones

Cultured – or as it is referred to by companies innovating the technology clean – meat is expected to be the next innovation to change the way the world gets its animal protein. Meat from animal cells grown in a lab seems like science fiction but it is around the corner from hitting your supermarket shelves. The technology has been developed but how these companies intend on scaling up their production to meet retail demands remains a mystery. So far companies have relied on seed and early stage investment from venture capital companies and private sources to fund research. Predictions …


The Effects Of Providing Social And Nutritional Enrichment To Dairy Calves On Development, Behavior And Learning, Kendra Leigh Kutina Jun 2019

The Effects Of Providing Social And Nutritional Enrichment To Dairy Calves On Development, Behavior And Learning, Kendra Leigh Kutina

Master's Theses

The objective of this study was to measure the effects of both a nutritional (water nipple) and social (partner calf) enrichment on calf body weight, grain intake, water intake, behavior and learning. The enrichments included 1) water provided from a nipple vs. a bucket (nutritional) and 2) visual and tactile access to a partner vs. isolated rearing with no visual or tactile access to a partner calf (social). A total of 72 Holstein and Jersey dairy calves were pseudo-randomly distributed into 4 treatments at birth [Individual/Bucket (IB), Paired/Bucket (PB), Individual/Nipple (IN), Paired/Nipple (PN)]. Socially and nutritionally enriched calves drank more …


Islands In A Sea Of Aaruul: Globalization And Mongolian Cheesemakers, Pearse Anderson Apr 2019

Islands In A Sea Of Aaruul: Globalization And Mongolian Cheesemakers, Pearse Anderson

Independent Study Project (ISP) Collection

Despite being a sparsely-populated country with less than 2% of its land arable, Mongolia has developed a rich and complex food culture, notably for its meat and dairy products, which could soon be at an historic high thanks to the tens of millions of animals on Mongolian pastureland. Many Mongolians and non-Mongolians view the countryside as a sea of milk that is currently being underutilized for economic exploitation. Various projects, whether funded and organized by international NGOs, the Mongolian government, or private companies, have tried to use Mongolian’s dairy resources to fill Mongolian demand, with more recent private ventures also …


Evaluating The Impact Of Feed Supplementation On Productive And Reproductive Efficiency In Smallholder Dairy Cattle In Arusha, Tanzania, Hayley Hall Apr 2019

Evaluating The Impact Of Feed Supplementation On Productive And Reproductive Efficiency In Smallholder Dairy Cattle In Arusha, Tanzania, Hayley Hall

Independent Study Project (ISP) Collection

This study was performed to determine if supplementing concentrates and/or minerals significantly affect productive and reproductive efficiency in smallholder dairy cattle in Arusha, Tanzania. The goal was to estimate the necessity and effectiveness of supplementing a forage diet on production and reproduction. Data was collected through interviews of small scale dairy cattle owners in nine regions within and around Arusha. Productive efficiency was measured by milk yield per cow per day. Reproductive efficiency was evaluated by the amount of time to heat resumption after calving and reproductive disease status. This was studied because determining the factors that improve the efficiency …


Perceptions Of On-Farm Emergency Slaughter For Dairy Cows In British Columbia, Katherine E. Koralesky, David Fraser Jan 2019

Perceptions Of On-Farm Emergency Slaughter For Dairy Cows In British Columbia, Katherine E. Koralesky, David Fraser

Slaughter and Slaughtering Practices Collection

Some jurisdictions permit on-farm emergency slaughter (OFES) as one end-of-life option for dairy cows and other animals that cannot be transported humanely but are deemed fit for human consumption. Anecdotal reports suggest that OFES is controversial among dairy industry professionals, but to date their perceptions of OFES have not been studied systematically. Twentyfive individual interviews and 3 focus groups with 40 dairy producers, veterinarians, and other professionals in British Columbia, Canada, revealed positive and negative perceptions of OFES influenced by (1) individual values, (2) the perceived operational legitimacy of OFES, and (3) concern over social responsibility and public perception of …
