Use Of An Activity Monitoring System As Part Of The Cal Poly Dairy Breeding Protocol, Trevor Nutcher

Dairy Science

The objective of this study, is to determine the effectiveness of an activity monitoring system as an integral part of the Cal Poly Dairy breeding protocol. Dairy herd reproductive efficiencies have dropped in the past 40 years. Increased milk production, and genetic advancements towards more milk production, have led to reproductive rates declining. An advanced breeding program is needed to become more efficient in this area. The study consisted of the evaluation of one option, Heatime™ by MICRO Dairy Logic, and comparing it to the commonly used programs in dairies today such as synchronization methods, pedometers, and other electronic detection …

Methane Digesters, Thomas Van Steyn

Dairy Science

Anaerobic digestion has many different avenues for opportunity in use on farms. The objective of my senior project is to determine the economic viability of alternative methane digesters on a dairy. Currently the conversion of animal manure to biogas through the process of anaerobic digestion is widely used in Europe. In the U.S. anaerobic digesters have become increasingly in demand by environmental groups and dairymen. Digesters environmental impact involves the benefit by capturing the biogas that comes off animal manure. Methane, a green house gas, is the one with the most concern that is captured by methane digesters. The biogas …

Like Mother Like Child: An Investigation Of Mother Characteristics And Child Temperaments, Tempus Fugitt

Statistics

Much research has gone into what biological and social factors raise the risk of children developing cognitive, social, or behavioral problems. This project looks at what characteristics of the mother are significantly associated with different temperaments in the child which may predict problems developed in the child later in life. These characteristics include mother’s age, her education level, household income, parenting attitudes, involvement with the child, and drug and alcohol use. Data was used from the Fragile Families and Child Wellbeing Study conducted by the Office of Population Research at Princeton University. Cumulative logistic regression was used to analyze the …

Controlling The Mineral Content Of Sweet Whey Powder In An Industrial Setting, Matthew W. Sawyer

Dairy Science

The objective of this project was to reduce the final ash content of sweet whey powder. The data for this project was collected over a two-week period, from July 13th to July 27th 2010 in a dairy plant in the Mid-West of the United States. The data is composed of particle size test, ash test, and pH test. The conclusions of this study are that multiple pre-heat treatment tank changes contribute to mineral content by requiring more buffering than usual. The low pH of this pre-heat liquid forces a need for more buffering. Particle segregation may play a role in …

Auto Dialer Wireless Smoke Detector/Alarm System, Manny Linhares

Electrical Engineering

Smoke Detectors/Alarms save the lives of over sixty percent of people each year in the United States. Most of the existing homes are still fitted with the normal smoke detectors either running out of the 120V ac wiring or out of a 9V dc battery. These alarms are perfectly fine to alert residents if there is a fire while they are home. But for people who are away from home when a fire occurs, it would be nice if they could be alerted automatically of such an occurrence and therefore be able to act upon the event by either calling …
