Impact Of Storage Temperature On Viability Of Microbial Inoculum For Estimating In Vitro Equine Digestibility, Delaney Brenne O'Donnell May 2020

Impact Of Storage Temperature On Viability Of Microbial Inoculum For Estimating In Vitro Equine Digestibility, Delaney Brenne O'Donnell

MSU Graduate Theses

This study evaluated the effect of storage temperature of equine fecal material on the viability of microbial inoculum used for in vitro equine digestibility trials. Fecal material was stored at four storage temperatures of 39°C for 15 minutes (control), 22°C for 6h, 3°C for 6h, and -18°C for 24h. Stored fecal material was used to form microbial inoculum for use in an Ankom Daisy II Incubator. Six different forage samples were digested in the Ankom Daisy II Incubator to evaluate interactions between storage condition of microbial inoculum and chemical composition of digested forage samples. After determination of dry matter digestibility …


Chemical Characterization Of Trichoderma Reesei Degraded Date Pits And Its Effect On Growth Performance And Intestinal Bacterial Population And Antioxidant Status - A Comparative Study With Mannose And Mannan-Oligosaccharide On Broiler, Salem Rashed Ali Rashed Al Yileili Jun 2019

Chemical Characterization Of Trichoderma Reesei Degraded Date Pits And Its Effect On Growth Performance And Intestinal Bacterial Population And Antioxidant Status - A Comparative Study With Mannose And Mannan-Oligosaccharide On Broiler, Salem Rashed Ali Rashed Al Yileili

Dissertations

With the increasing apprehension over food safety nowadays, there have been relentless efforts aiming for subrogating antibiotic growth promoters (AGPs) in poultry feeds. Thus, this research study aims at investigating the potential effects of using degraded date pits (DDP) as feedstuff and as a natural alternative for antibiotics in poultry feeding. Two feeding experiments were conducted. In experiment 1, the minimum time of feeding a diet containing 10% DDP is required to induce growth-promoting effects on broiler performance. In experiment 2, the influence of feeding 10% DDP was examined as feedstuff at 10% in broilers diets and a growth-promoting agent …
