Lamb Bacon: How The Method Of Brine Distribution And Addition Of A Dry Rub Influences Yields, Morgan Metheny

Animal Science

This study was conducted to test the whether lamb breasts can substitute as the raw material in producing a bacon product. Due to the difference in fat saturation between pork and lamb, this research was used to test how successful lamb absorbs the brine in order to make bacon. The yield results of two different processing techniques, injection and tumbling, were compared along with comparing the affect of adding a dry rub of seasonings to the lamb surface. The 120 lambs breasts were split into four groups of 30. Each group received a different treatment: plain tumbled, plain injected, seasoned …

The Effects Of Different Cryopreservation Techniques On The Survival Rate Of In Vitro Produced (Ivp) And Biopsied Bovine Blastocysts, Diana J. Gumber

Animal Science

This study’s objectives were to determine if the biopsy of expanded blastocysts prior to cryopreservation affected the survival rates and determine if there is a difference between slow-freezing in 10% glycerol, slow freezing in ethylene glycol, and vitrification in terms of survival rate of the embryos. Blastocoeles were reduced prior to cryopreservation by means of biopsy. Embryos for slow freezing were exposed to ethylene glycol (SynGRO Ethylene Glycol with Sucrose, BIONICHE, Pullman, WA, USA) or 10% glycerol (SynGRO 10% Glycerol, BIONICHE, Pullman, WA, USA) as cryoprotectants. Vitrified embryos were exposed to 10% and 40% ethylene glycol. Survival rate of biopsied …

The Envenoming Pandemic And The Misguided Views Of Snakes: Developing Sustainable Relationships Between Native Poisonous Snakes Of India And The Citizens Of Maharashtra Through The Use Of The Irula Model., Destiny Villanueva

Animal Science

Due to its vast population and general negative consensus regarding snakes, India is notorious for having more snakebite incidents than any other country. Snakes are simultaneously revered and feared in Indian religion and culture. This stigma is perpetuated through propaganda, family beliefs, and innate fears of snakes.These stigmas are more pronounced within rural areas, such as the region of Mahad within the state of Maharshtra. Envenoming is endemic in these areas, and others like them. The World Health Organization identified envenoming as one of the most neglected tropical diseases of the 21st century (Nature India, 2013). Additionally, both nonvenomous and …

Open Pulled Straw (Ops) Vitrification Of Mus Musculus Morula And Blastocyst Survival In Two Common Cryopreservation Medias, Gina Marie Cirimele

Animal Science

The objectives of this study were to: (1) determine an optimal cryoprotectant of mice embryos; and (2) determine whether morula or blastocyst stage is ideal for vitrification in both medias. One experiment was performed using two different medias for vitrification with open pulled straws (OPS) with morulae and blastocysts. In the first protocol, we called V, embryos were exposed to 10% ethylene glycol (EG) for 5 minutes, then 40% ethylene glycol and 0.6 M galactose for about 30 seconds, loaded into an OPS, and plunged into liquid nitrogen. In the second protocol, we called VG, embryos were exposed to 7.5% …

Efficiency Of Two Cryopreservation Methods Using Direct In-Straw Rehydration After Repeated Vitrification Of Mouse Embryos, Ashley Morgan Payne

Animal Science

Experiments were conducted to determine which of two direct in-straw rehydration methods was optimal for obtaining high survival of mouse embryos after repeated vitrification. The first vitrification method compared was a one-step design, designated “House method,” where embryos were equilibrated in 3.5 M ethylene glycol for 3 min before rapid plunge vitrification in 7 M ethylene glycol/0.5 M glucose/18% w/v Ficoll 70. The second method was the commercially available BoviPRO Embryo Vitrification Kit ^TM(MiniTube of America, Verona, WI), which first exposed embryos to 1.4 M glycerol for 5 min, then 1.4 M glycerol/3.6 M ethylene glycol for 5 min, …

Analysis Of Pacific Harbor Seal Survival At Wolf Hollow Wildlife Rehabilitation Center, Friday Harbor, Wa, Casey L. Martinez

Animal Science

The Wolf Hollow Wildlife Rehabilitation Center cares for and releases dozens of Pacific Harbor Seals each year. Analysis of 161 seal records from mid-2004 to 2010 showed that the sex, weight, and age of the incoming seals are not statistically significant predictors of survival to release. The absence of wounds and injuries, on the other hand, is correlated with increased survival about two times greater than that of wounded seals.
