The Effect Of Rider Level On Equine Mean Heart Rate At The Trot, Jacqueline Marinoff Apr 2013

The Effect Of Rider Level On Equine Mean Heart Rate At The Trot, Jacqueline Marinoff

Honors Theses and Capstones

The effect of riders at two different levels of riding ability on the mean heart rates (HR) of school horses at the trot was studied. Five horses were each paired with a beginner (n=4) and an intermediate (n=5) rider, and the mean HR generated by the two riders at the trot were compared for each horse. There was a significant (p


Effects Of Incremental Dietary Levels Of Ground Flaxseed On Milk Production, Ruminal Metabolism, And Enteric Methane Emissions In Organic Dairy Cows, Katie Velez Oct 2012

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 …


The Effects Of Dependent Infants On The Social Behavior Of Mantled Howler Monkeys (Alouatta Palliate), Keziah Katz Apr 2012

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.
