Effect Of Milk Replacer Composition On Growth And Rumen Development Of Neonatal Holstein Calves, Anthony Joseph Bridges
Effect Of Milk Replacer Composition On Growth And Rumen Development Of Neonatal Holstein Calves, Anthony Joseph Bridges
LSU Master's Theses
A study was conducted to determine effects of differing fat and protein levels in commercial milk replacers on the growth performance and rumen development of neonatal Holstein calves. Fifty-three calves (23 male; 30 female) were assigned to one of three dietary treatments which included 3 milk replacers (20/20; 25/15; 28/20) fed once per day at 10% of birth weight through weaning. Calves were offered a 20% CP calf starter and water free choice beginning on day 5. All calves were weaned on day 42. Body weights were measured at birth and weekly through weaning. Additionally, hip height, wither height, and …

Life History Characteristics Of Alligator Gar, Atractosteus Spatual, In The Bayou Dularge Area Of Southcentral Louisiana, Kayla Cheree Dibenedetto
LSU Master's Theses
The alligator gar Atractosteus spatula is a large, long-lived, physostomous fish that inhabits aquatic habitats throughout the central U.S., ranging from Oklahoma southward to the Gulf of Mexico. Unfortunately, the alligator gar has declined significantly in abundance throughout much of its historic range and is now considered vulnerable to localized extirpation. The goal of this study was to provide basic data on the ecology and life history of a commercially-exploited alligator gar population in south Louisiana. This study also focused on age determination and alternate aging techniques such as sectioned otoliths and sectioned scales. From 10 April 2007 through 21 …
