Automated Activity Monitoring Of Estrus And Time Of Ovulation (2013), Jeffrey S. Stevenson Jan 2013

Automated Activity Monitoring Of Estrus And Time Of Ovulation (2013), Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Detection of estrus can be facilitated by use of automated activity monitors that measure physical activity. Increased physical activity is largely correlated with estrus. Our objective was to determine when ovulation occurs relative to increased physical activity so we could recommend optimal timing of insemination to maximize conception rates in lactating dairy cows. Cows (n = 65) were fitted with pressure-sensitive rump-mounted transmitters (HeatWatch; HW) that are activated by a mounting herdmate to indicate standing estrus. The same cows also were fitted with neck-mounted activity monitors (Select Detect; SD). Additional cows (n = 68) were fitted with only the activity …

Consumer Acceptance Of Cysteine-Enhanced Yogurt, Soumya Bala, Karen A. Schmidt Jan 2013

Consumer Acceptance Of Cysteine-Enhanced Yogurt, Soumya Bala, Karen A. Schmidt

Kansas Agricultural Experiment Station Research Reports

Within cells, cysteine can be synthesized from methionine by the enzyme γ-cystathionase. Cysteine is then utilized to synthesize glutathione, which has many functions in cells that contribute to good health. Certain subpopulations, however, especially the elderly, have decreased γ-cystathionase activity. Thus, dietary cysteine may be beneficial in maintaining health. In previous reports, a yogurt with enhanced cysteine content was made by incorporating whey protein isolate (WPI) into the mix's dairy base combined with a process treatment to minimize cysteine denaturation. The gel quality of this yogurt matched or exceeded that of a yogurt that was formulated and processed to mimic …
