Dairying continues to change with economic and environmental demands of today’s fast moving society. Feed costs continue to rise and now account for a large majority of expenses on dairies; especially protein, which has become expensive to purchase. I believe that Algae can serve as a possible solution to aid in alleviating this problem. Algae grow rapidly and consume undesirable carbon dioxide to release oxygen to the environment, making it an environmentally friendly source of feed. There are particular strands of algae that are high in protein. During the course of this project, I intend to discover how effective protein …

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 …
