Effects Of Incremental Dietary Levels Of Ground Flaxseed On Milk Production, Ruminal Metabolism, And Enteric Methane Emissions In Organic Dairy Cows, Katie Velez
Honors Theses and Capstones
Ground Flaxseed (Linum uitatissimum) is a lipid supplement that is commonly fed to dairy cows. It is believed that supplemental lipid can change the Fatty Acid (FA) composition in the milk, and decrease methane production. Twenty lactating organic Jersey cows, housed at the UNH Organic Dairy Research Farm (ODRF), were randomly assigned to five replicated 4 × 4 Latin squares to investigate the effects of increasing dietary levels of ground flaxseed (0, 5, 10, or 15% of the diet dry matter) on animal fperformance (e.g., dry matter intake, milk production, milk composition), ruminal metabolism, and enteric methane emissions. Each …
Variations In Carotenoids In Plasma From Jersey Cows At An Organic Dairy Compared To A Conventional Dairy Over Time, Jillian M. Smith
Variations In Carotenoids In Plasma From Jersey Cows At An Organic Dairy Compared To A Conventional Dairy Over Time, Jillian M. Smith
Honors Theses and Capstones
Interest in organic milk is increasing. By USDA Certified Organic standards, animals must be fed on pasture for a minimum of 120 days. Research indicates that various factors such as diet impact the nutritional quality and composition of milk. The objective of this study was to understand how feeding practices affected bovine plasma carotenoid concentrations over time. Plasma samples were collected from 9 cows fed on pasture at an organic dairy and from 9 cows fed total mixed ration (TMR) at a conventional dairy. Components were extracted from the plasma and separated via High Performance Liquid Chromatography. Results showed that …
The Effects Of Dependent Infants On The Social Behavior Of Mantled Howler Monkeys (Alouatta Palliate), Keziah Katz
The Effects Of Dependent Infants On The Social Behavior Of Mantled Howler Monkeys (Alouatta Palliate), Keziah Katz
Honors Theses and Capstones
Six weeks of observation on eight groups of wild mantled howler monkeys revealed that the presence of a dependent infant alters the frequency of social interactions between a female with an infant and other adult monkeys. Males preferred to spend time with females without infants but still spent more time with females with infants than with males. Females without infants spent significantly less time with females with infants than with males or other females without infants and females with infants decreased their frequency of social interaction overall without preference for males, females or other females with infants.
