A Comparative Study Of The Effects Of Microalgae On Poultry Production, Taylor Kaitlyn O'Lear Reid
A Comparative Study Of The Effects Of Microalgae On Poultry Production, Taylor Kaitlyn O'Lear Reid
Master's Theses
Research has shown Spirulina to be a viable feedstuff in poultry production. Other species of microalgae are being studied to determine their effects on poultry production. This project compared four microalgaes: Hydrodictyon, Vaucheria, Uronema, and Spirulina and was broken down into three trials. The first experiment investigated the digestibility of an algae species, Spirulina, in broiler chicken diets. Eighty, 25-day-old Ross 708 broiler chicks were sorted into 20 metabolism cages and received one of two diets: Control Diet or Test Diet (75% basal diet + 25% Spirulina). The apparent ileal amino acid digestibility (AIAAD) of lysine, methionine, cysteine, threonine, isoleucine, …
Effect Of Storage Period And Treatment On The Composition And Digestibility Of Olive Pomace In Cattle, Alexis Cecilia Ulloa
Effect Of Storage Period And Treatment On The Composition And Digestibility Of Olive Pomace In Cattle, Alexis Cecilia Ulloa
Master's Theses
Utilizing local by-products can serve to significantly reduce the current feed costs for ruminant producers. The objective of this study is (1) to evaluate the effects of chemical and bacterial inoculants in combination with ensiling, on the nutritional value and ensiling compatibility of olive pomace (OP) and (2) to identify the most biologically favorable treatment and ensiling day of OP for feeding to cattle. Freshly centrifuged OP (Olivas de Oro Olive Company, Creston, CA) was treated with one of four treatments: (1) no additives (control; CONT); (2) urea applied at 5% of DM (UREA; Agrium U.S. Inc, Loveland, CO); (3) …
Digestibility Of Two Complete Pelleted Diets By The Horse (Equus Caballus) As A Model Animal For Nondomestic Hindgut Fermenters, Emily M. Schwartz
Digestibility Of Two Complete Pelleted Diets By The Horse (Equus Caballus) As A Model Animal For Nondomestic Hindgut Fermenters, Emily M. Schwartz
Master's Theses
Estimating nutrient and energy requirements of exotic animals is a necessary component of nutrition management in zoos and other wildlife facilities. In the absence of species-specific data, domestic animal models are often referenced. Herbivorous hindgut fermenters, such as horses, zebra, and rhinoceros, rely on microbial fermentation in the cecum and colon to utilize dietary structural carbohydrates. The study objective was to measure the digestible energy of two (LOW, HIGH) complete pelleted diets by the horse as a model for nondomestic hindgut fermenters. Seven, individually housed, adult Quarter Horse (Equus caballus) geldings were assigned to one of two diets as 100% …
In Vivo And In Vitro Digestibility Of A Complete Pelleted Feed In Horses, Cassandra Renee Sweeney
In Vivo And In Vitro Digestibility Of A Complete Pelleted Feed In Horses, Cassandra Renee Sweeney
Master's Theses
ABSTRACT
COMPLETION OF AN IN VIVO DIGESTIBILITY TRIAL IN HORSES AND IN VITRO DIGESTIBILITY ASSAY DEVELOPMENT
Cassandra Renee Sweeney
In vivo analysis of equine feed digestibility has been the gold standard since the late 1800's, although it can be time consuming, costly, and labor intensive. In vitro digestibility analysis may be more economical and beneficial to both feed manufacturers and consumers. The availability of accurate in vivo data is crucial for critical evaluation and validation of any potential in vitro method (Coles et al., 2005). Ten adult American quarter horse geldings were used in the in vivo digestibility evaluation of …
