Effects Of Carbaryl And Γ-Bhc On The Histology Of Midgut And Digestive Enzyme Profiles In The Third Instar Larvae Of Fruit-Sucking Moth, Othreis Materna (Linn.) (Lepidoptera: Noctuidae), Chitralekha Deshmukh, Aneel Mohite, Jagdish Shinde Jan 2009

Effects Of Carbaryl And Γ-Bhc On The Histology Of Midgut And Digestive Enzyme Profiles In The Third Instar Larvae Of Fruit-Sucking Moth, Othreis Materna (Linn.) (Lepidoptera: Noctuidae), Chitralekha Deshmukh, Aneel Mohite, Jagdish Shinde

Turkish Journal of Zoology

The effects of LC50 dose of carbaryl and gamma benzene hexachloride (γ-BHC) on midgut histopathology and midgut enzyme activities in the third instar larvae of fruit-sucking moth, Othreis materna (L.) were studied. The sub-lethal doses of carbaryl and \gamma-BHC caused initially hypersecretory activity in the midgut epithelial cells leading to deposition of numerous secretory vesicles in the extraperitrophic space, clumping of chromatin matter, and regression and vacuolization of the columnar cells, but later on they were recovered within 24 h. Activities of the midgut digestive enzymes (amylase, invertase, lipase, and protease) were significantly affected. Carbaryl enhanced (P < 0.05) the amylase, invertase, lipase, and protease activities initially up to 4 h and 6 h of treatment, but after 24 h of treatment, amylase and invertase activities resumed while an inhibitory effect was observed on lipase and protease activities. \gamma-BHC did not affect the amylase and protease activities up to 4 h but later on it significantly (P < 0.05) enhanced their activities up to 6 h and 12 h, respectively. Thereafter it fell without showing any sign of recovery. \gamma-BHC enhanced (P < 0.05) invertase and lipase activities but they fell after 4 h treatment.

Effect Of Corn Dried Distillers Grains With Solubles (Ddgs) On Growth Performance And Carcass Characteristics Of Growing-Finishing Gilts With Previous Exposure To Ddgs In The Nursery, Thomas E. Burkey, Phillip S. Miller, Roman Moreno, Erin E. Carney

Nebraska Swine Reports

The objective of this experiment was to evaluate the effects of high concentrations of distillers dried grains with solubles (DDGS; 30%) on growth performance and carcass characteristics of gilts, during growing-finishing, that were previously fed high concentrations of DDGS during the nursery phase. Overall (week I to 16), the following observations are noteworthy: 1) among pigs that were fed DDGS in the nursery, average daily gain (ADG) and final body weight (BW) tended (P < 0.10) to be lower during growing-finishing compared to pigs that did not receive DDGS in the nursery; 2) among pigs that received DDGS during growing-finishing, ADG tended (P < 0.10) to be lower compared to pigs that did not receive DDGS during growing-finishing; and 3) among pigs that received DDGS in both the nursery and during growing-finishing, ADG and final BW was decreased (P < 0.04) compared to pigs with no prior exposure to DDGS. With respect to carcass characteristics, loth-rib back fat was greater (P < 0.05) at the end of finisher 2 among pigs that did not receive DDGS in the nursery and hot carcass weight tended (P < 0.07) to be decreased among pigs that received DDGS in both the nursery and during growing finishing. This research indicates that the inclusion of high concentrations of DDGS in both the nursery and growing finishing periods may result in negative effects on growth performance and carcass characteristics

The Hyperinsulinemia-Hyperleptinemia Syndrome In Horses: Assessment Of Methods Of Diagnosis And Differential Effects Of Insulin Injection On Glucose, Glucagon And Nonesterified Fatty Acids In Plasma, Thomas Joseph Caltabilota Jan 2009

The Hyperinsulinemia-Hyperleptinemia Syndrome In Horses: Assessment Of Methods Of Diagnosis And Differential Effects Of Insulin Injection On Glucose, Glucagon And Nonesterified Fatty Acids In Plasma, Thomas Joseph Caltabilota

LSU Master's Theses

Plasma leptin concentrations in horses have been shown to vary widely. However, many factors may perturb these measurements. Previous research has documented a link between hyperinsulinemia and hyperleptinemia in horses. This condition has been speculated to be associated with components of equine metabolic syndrome, such as insulin resistance and laminitis. However, many of the methods accepted in diagnosing these metabolic abnormalities are expensive and often difficult to perform. Thus, the objectives of the experiments in this thesis were 1) to determine if it is possible to differentiate hyperleptinemic horses from normal ones by hormone manipulation with dexamethasone, a glucocorticoid analog; …

Isolation Of A 3-Methylindole-Producing Bacterium From A Swine Waste Lagoon, Michelle L. Fusting Jan 2009

Isolation Of A 3-Methylindole-Producing Bacterium From A Swine Waste Lagoon, Michelle L. Fusting

Mahurin Honors College Capstone Experience/Thesis Projects

With an increase in animal production closer to populated areas, odorants from animal waste are a rapidly rising concern. 3-Methylindole (3-MI) is an odorant produced from the biodegradation of L-tryptophan by bacteria in animal waste. Currently, no 3-MI producing bacterium has been isolated from swine waste, and isolation of such an organism would provide insight into production and regulation of 3-MI. Therefore, an experiment was designed to isolate a 3-MI producer based on previous work which indicates the presence of Fe(III) increases 3-MI levels. An Enterococcus sp. was isolated from WKU's primary swine waste lagoon in rich, anaerobic medium plus …

Effect Of Estrus Synchronization With A Single Injection Of Prostaglandin During Natural Service Mating, Daniel Larson, Jacqueline A. Musgrave, Richard N. Funston

Nebraska Beef Cattle Reports

Records from unsynchronized cows (n = 2073; 60-day breeding season) were compared with records from synchronized cows (n = 517; 45-day breeding season) collected between 2000 and 2006. A single injection of prostaglandin F2α was administered approximately 108 hours after bull turn-in to synchronize estrus in spring calving mature beef cows. Estrus synchronization increased the percentage of cows calving in the first 21 days without affecting pregnancy rates. However, weaning BW of calves was not significantly different. Estrus synchronization improves synchrony of calving in a shorter breeding season with similar overall pregnancy rates.

Nebraska Beef Cattle Reports

Data were compiled from 4,143 cattle on byproduct feeding experiments. Incidence of polioencephalomalacia was small (0.14%) in diets containing 0.46% or less sulfur (S). Incidences of polioencephalomalacia increased when cattle were fed diets above 0.46% S and especially above 0.56%. Phosphoric acid successfully replaced sulfuric acid in ethanol fermentation, but the amount and cost of phosphoric acid likely limit the economic feasibility of its use.
