Associations Of Housing, Management, Milking Activity, And Standing And Lying Behavior Of Dairy Cows Milked In Automatic Systems, Justine A. Deming, Renée Bergeron, Kenneth E. Leslie, Trevor J. Devries

Farm Animal Husbandry Collection

The objective of this cross-sectional study was to describe the housing, feeding management, and characteristics (parity and stage of lactation) of cows on commercial automatic milking system (AMS) dairies and their associations with the standing and lying behavior patterns and milking activity (frequency and yield) of lactating dairy cows. Thirteen AMS herds were enrolled in the study, with an average herd size of 71 ± 30 (mean ± SD; range: 34 to 131) lactating cows. All of the herds used freestall barns, each set up for free cow traffic to the AMS. On-farm measurements were taken to determine stocking density …

Compost Bedded Pack Barns: Management Practices And Economic Implications, Randi Alyson Black Jan 2013

Compost Bedded Pack Barns: Management Practices And Economic Implications, Randi Alyson Black

Theses and Dissertations--Animal and Food Sciences

Compost bedded pack (CBP) barn design and pack maintenance procedures vary considerably, making advising and problem-solving challenging. One objective of this research was to characterize herd performance and management practices employed by Kentucky CBP managers (42 farms and 47 CBP facilities). Producer satisfaction, changes in historical bulk-tank somatic cell count, and improvement in herd performance parameters after transitioning to a CBP barn support reported CBP barn system benefits. Daily milk production increased from before moving into the CBP barn to the second year after (29.3 ± 0.3 vs. 30.7 ± 0.3 kg, respectively; P < 0.05) for farms using the CBP barn as the primary housing facility (n = 8). Increasing stirring frequency, stirring depth, and ambient temperatures increased pack temperature. Increased drying rate decreased CBP moisture. Increased 20.3 cm depth CBP temperature and ambient temperatures improved cow hygiene. Mastitis-causing bacteria thrive in conditions similar to optimal composting bacteria conditions, making reduction of these bacteria difficult in an active composting environment. Producers must pay attention to other management areas where preventive measures can be employed. The New Dairy Housing Investment Analysis Dashboard provides users an interactive and flexible decision tool to make more informed facility investment decisions.

Influence Of Various Health Beneficial Spices On Some Characteristics Of Yogurt Culture Bacteria Lactobacillus Acidophilus, And Sensor Acceptability Of Spicy Probiotic Yogurt, Margie Michelle Sanchez-Vega Jan 2013

Influence Of Various Health Beneficial Spices On Some Characteristics Of Yogurt Culture Bacteria Lactobacillus Acidophilus, And Sensor Acceptability Of Spicy Probiotic Yogurt, Margie Michelle Sanchez-Vega

LSU Doctoral Dissertations

There is a pronounced public awareness about herbal remedies. Garlic and ginger have antibacterial properties and prevent cardiovascular diseases. Onion and turmeric decrease the risk of diabetes and like garlic, they have anticancer properties. Streptococcus thermophilus, Lactobacillus bulgaricus and Lactobacillus acidophilus are lactic acid bacteria that produce lactase and reduce the symptoms of malabsorption. Earlier work has shown the influence of spice extracts but the influence of pure spice juice on yogurt culture bacteria is not known. Characteristics of yogurt culture bacteria were measured by suspending freshly thawed cultures in 0.1% peptone water (growth), acidified MRS broth (acid tolerance), MRS-Thio …
