Concentrations Of Nefa, Ss-Hba, Triglycerides, And Certain Blood Metabolitesin Healthy Colored Angora Goats During The Peripartum Period, Funda Eşki̇, İbrahi̇m Taşal, Mehmet Aki̇f Karsli, Sai̇t Şendağ, Bariş Atalay Uslu, Henrik Wagner, Axel Wehrend

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to determine the changes in serum nonesterified fatty acid (NEFA), serum ß-hydroxybutyric acid (ß-HBA), triglycerides, Ca, Na, and other metabolites (bilirubin, glutamate dehydrogenase (GLDH)) in the blood of grazing, healthy goats at the time of parturition. Blood samples were taken weekly from the jugular vein of 11 goats, starting at week 2 antepartum (ap) until week 9 postpartum (pp). NEFA and ß-HBA concentrations increased from week 2 ap to 2 weeks pp. The increase in NEFA level was not significant; however, the ß-HBA levels were higher (P < 0.05) 2 weeks pp compared to the levels at 2 weeks ap. Triglycerides were recorded at maximum levels (P < 0.05) 2 weeks ap, with the lowest concentrations at 3 weeks pp. Bilirubin levels consistently increased up to 7 weeks pp, followed by a decrease. However, these changes were not significant. Similarly, GLDH activities increased until week 8 pp. A significant difference (P < 0.05) was recorded between the 1st week and 8th week pp. Ca and Na levels were lower during the 1st week pp and increased at 3 weeks pp. The results show that there are characteristic alterations of some metabolic blood parameters in goats around the time of parturition, which may be related to physiological changes.

Influence Of Individual Or Mixed Cellulase And Xylanase Mixture On In Vitro Rumen Gas Production Kinetics Of Total Mixed Rations With Different Maize Silage And Concentrate Ratios, Mona Mohamed Mohamed Yasseen Elghandour, Ahmed Eid Kholif, Ofelia Márquez-Molina, José Fernando Vázquez-Armijo, Anil Kumar Puniya, Abdelfattah Zeidan Mohamed Salem

Turkish Journal of Veterinary & Animal Sciences

This study assessed the effects of cellulase, xylanase, and their mixture (1:1, v/v) on in vitro rumen fermentation of five mixed rations with different maize silage (F) to concentrate (C) ratios (0F:100C, 25F:75C, 50F:50C, 75F:25C, 100F:0C). Samples were incubated using rumen inoculum from Brown Swiss cows fed ad libitum a total mixed ration of concentrate and alfalfa hay (1:1). Gas production (GP) was recorded after 2, 4, 6, 8, 10, 12, 24, 36, 48, and 72 h of incubation. Interaction effects (P < 0.0001) were observed between type of ration and enzyme for discrete lag time prior to GP. Ration type affected asymptotic GP (linear and quadratic, P < 0.0001) and in vitro GP at 24 h onward. Moreover, rations affected pH (linear and quadratic, P < 0.0001), dry matter degradability (quadratic, P = 0.05), metabolizable energy (linear, P = 0.038), short-chain fatty acids (linear, P = 0.0005), gas yield from truly digested dry matter at 24 h (linear, P = 0.0026), and microbial crude protein yield (linear, P = 0.0264). The most effective rations for in vitro GP during different times differed between different measured parameters. Enzyme administration was more effective when the ratio of maize silage was increased.

Turkish Journal of Veterinary & Animal Sciences

This study was undertaken to measure the effect of fattening duration (60, 80, and 100 days) on growth performance and carcass characteristics of male kids from indigenous Hair and Honamlı goat breeds reared under intensive fattening systems in Turkey. Fattening duration had a significant effect (P < 0.001) on the fattening performance and a number of carcass characteristics of kids. An interaction was detected between genotype and fattening duration for average daily gain (ADG). Hair goat kids grew at a faster rate than Honamlı kids in the 20-40 day and 40-60 day fattening periods, but they maintained relatively similar ADGs within other fattening periods. On average, over the course of the fattening trial, Honamlı kids grew at an average daily rate of 209 g/head, while Hair goat kids grew at a daily rate of 231 g/head. Dressing percentage and carcass lean and fat percentages of kids increased (P < 0.05-0.001) with slaughter age and weight for both genotypes, whereas the percentage of bone decreased (P < 0.001) with each successive fattening period. No genotypic differences were detected for a number of carcass characteristics at the time of slaughter, with the exception of relatively higher (P < 0.01) fat deposit rates within the kidney and pelvic areas for Hair kids.

Effects Of Long-Term Starvation And Refeeding On Fatty Acid Metabolism-Relatedgene Expressions In The Liver Of Zebrafish, Danio Rerio, Ayşe Ölmez, Mehtap Bayir, Chunfang Wang, Abdulkadi̇r Bayir Jan 2015

Effects Of Long-Term Starvation And Refeeding On Fatty Acid Metabolism-Relatedgene Expressions In The Liver Of Zebrafish, Danio Rerio, Ayşe Ölmez, Mehtap Bayir, Chunfang Wang, Abdulkadi̇r Bayir

Turkish Journal of Veterinary & Animal Sciences

A 70-day starvation was conducted to determine the effects of long-term starvation on whole-body polyunsaturated fatty acid (PUFA) composition and fatty acid metabolism-related gene expression in the liver of zebrafish, Danio rerio. The starvation period was followed by a 15-day refeeding period to test recovery of both PUFA composition and gene expression levels. It was found that n-3 PUFA and arachidonic acid levels increased during starvation and returned to normal values after refeeding (P < 0.05). Expression of seven (elovl5, fads2, cpt1-β, acox1, acadvl, fabp1a, and fabp7a) of eight total genes downregulated significantly towards the end of the starvation. As a result of refeeding, gene expression of elovl5 and ppar-α returned to the normal levels. Therefore, it was concluded that, in general, mRNA expression of genes involved in fatty acid metabolism was negatively influenced by long-term starvation (70 days); there was no direct relationship between whole-body fatty acid composition and hepatic gene expressions; and 15-day refeeding was insufficient for recovery of starvation-based metabolic losses in zebrafish.

Turkish Journal of Veterinary & Animal Sciences

Pharmacokinetics (PK), pharmacodynamics (PD), and PK/PD ratios of a new solvate of enrofloxacin (enrofloxacin hydrochloride-dihydrate; enro-C), were studied in hamsters. Enrofloxacin from Baytril1397904493 5% (enroR) served as the reference preparation. Two groups of 60 Syrian golden hamsters were intramuscularly injected individually with 10 mg/kg of enroR or with enro-C. Tissue and serum samples were obtained for 72 h; enrofloxacin concentrations were determined by HPLC with UV detection. Ninety percent minimum inhibitory concentrations (MIC90) were determined for strains of methicillin-resistant Staphylococcus aureus, Leptospira interrogans, and Escherichia coli. All PK variables were statistically different between groups (P < 0.01). CMAX of enrofloxacin for enro-C was 17.3 μg/mL and it was 2.6 μg/mL for enroR. AUC was considerably higher for enro-C (459.2 μg/mL h vs. 19.9 μg/mL h). There were no statistically significant differences in MIC90 values between enroR and enro-C. Tissue concentrations of enro-C in all cases were higher and remained above the MIC for longer periods than those of enroR. Relevant PK/PD ratios for enrofloxacin (AUC/MIC ? 125 and CMAX > MIC = 10-12) are consequently …

Cows And Plows: Science-Based Conservation For Grassland Songbirds In Agricultural Landscapes, Marisa K. Lipsey Jan 2015

Cows And Plows: Science-Based Conservation For Grassland Songbirds In Agricultural Landscapes, Marisa K. Lipsey

Graduate Student Theses, Dissertations, & Professional Papers

Temperate grasslands are among earth’s most imperiled ecosystems. In North America, steep declines of endemic songbird populations indicate that grassland loss and degradation may be approaching critical levels. Grasslands are agricultural landscapes largely (~85%) under private ownership with little formal protection status. Remaining bird populations depend on grazing lands that have not been converted to cropland. We combine regional data from a hotspot for grassland bird diversity (northeast Montana, USA; 26,500-km2) with continental data spanning the northern Great Plains (1,000,000-km2) to evaluate how land use and management influence bird distribution and abundance. Regionally, habitat used by seven grassland specialists spanned …

A Quantitative And Molecular Evaluation Of Bovine Respiratory Disease, Growth Traits, And Carcass Traits In Crossbred Steers, Samantha Lidia Miller Jan 2015

A Quantitative And Molecular Evaluation Of Bovine Respiratory Disease, Growth Traits, And Carcass Traits In Crossbred Steers, Samantha Lidia Miller

LSU Master's Theses

The first objective of the two studies presented herein evaluated on farm sources of variation and correlated effects contributing to BRD incidence in a population of crossbred steers sent to the feedlot from 2010-2013. Analyses revealed that incidence of BRD was lowly positively correlated to birth weight (BW) and lowly negatively correlated to weaning weight (WW), hip height (HH), sire breed, site, and birth year. These results indicate that the traits analyzed herein are not precursors for BRD in the current population. However, since little is still known about the correlation between genetic predisposition to BRD and animal performance, further …

Live And Carcass Characteristics Of Boer- And Savannah-Cross Kid Buckling Goats Fed Dried Distillers Grain With Solubles, James Neil Maynard

LSU Master's Theses

The available supply of domestic goat meat has not matched the increased demand for goat meat. High cost of production is a concern of goat producers, with feed being a major factor in input expenses. Increasing slaughter weight of kid meat goats would increase the available goat meat, but requires added nutrition beyond that obtained from typical forage based systems for goat production. Savannah bucklings (n=31) and Boer bucklings (n=28) were stratified by weight and breed and were randomly assigned a treatment of 0 (T1), 15 (T2), 30 (T3), or 45 (T4) percent dried distillers grain with solubles (DDGS).

Casitas are artificial shelters used by fishers to aggregate Caribbean spiny lobsters (Panulirus argus) for ease of capture. However, casitas may function as an ecological trap for juvenile lobsters if they are attracted to casitas and their growth or mortality is poorer compared with natural shelters. We hypothesized that juvenile lobsters may be at particular risk if attracted to casitas because they are less able than larger individuals to defend themselves, and do not forage far from shelter. We compared the nutritional condition, relative mortality, and activity of lobsters of various sizes in casitas and natural shelters in adult and …

The Effect Of Parental Size On Spermatophore Production, Egg Quality, Fertilization Success, And Larval Characteristics In The Caribbean Spiny Lobster, Panulirus Argus, Mark J. Butler Iv, Alison Macdiarmid, Gaya Gnanalingam Jan 2015

The Effect Of Parental Size On Spermatophore Production, Egg Quality, Fertilization Success, And Larval Characteristics In The Caribbean Spiny Lobster, Panulirus Argus, Mark J. Butler Iv, Alison Macdiarmid, Gaya Gnanalingam

The average size of spiny lobsters (Decapoda; Palinuridae) has decreased worldwide over the past few decades. Market forces coupled with minimum size limits compel fishers to target the largest individuals. Males are targeted disproportionately as a consequence of sexual dimorphism in spiny lobster size (i.e. males grow larger than females) and because of protections for ovigerous females. Therefore, overexploitation of males has led to sperm limitation in several decapod populations with serious repercussions for reproductive success. In the Caribbean spiny lobster, Panulirus argus, little is known about the effect of reduced male size on fertilization success or the role …

Rapid Recovery Of An Urban Remnant Reptile Community Following Summer Wildfire, Robert A. Davis, Tim S. Doherty Jan 2015

Rapid Recovery Of An Urban Remnant Reptile Community Following Summer Wildfire, Robert A. Davis, Tim S. Doherty

Research outputs 2014 to 2021

Reptiles in urban remnants are threatened with extinction by increased fire frequency, habitat fragmentation caused by urban development, and competition and predation from exotic species. Understanding how urban reptiles respond to and recover from such disturbances is key to their conservation. We monitored the recovery of an urban reptile community for five years following a summer wildfire at Kings Park in Perth, Western Australia, using pitfall trapping at five burnt and five unburnt sites. The reptile community recovered rapidly following the fire. Unburnt sites initially had higher species richness and total abundance, but burnt sites rapidly converged, recording a similar …

The Effects Of Post-Exercise Consumption Of A Kefir Beverage On Performance And Recovery During Intensive Endurance Training, Keely Virginia O'Brien Jan 2015

The Effects Of Post-Exercise Consumption Of A Kefir Beverage On Performance And Recovery During Intensive Endurance Training, Keely Virginia O'Brien

LSU Doctoral Dissertations

This study was designed to determine whether kefir accentuates the positive health benefits assessed by measures in fitness and/or body composition, as a measure of cardiovascular disease risk as well as the biomarker c-reactive protein. Sixty-seven adult males and females aged 18-35 years were assigned to one of four groups: 1) endurance training + control beverage, 2) endurance training + kefir beverage, 3) active control + control beverage or 4) active control + kefir beverage. The exercise groups completed 15 weeks of structured endurance training while the active control groups maintained their usual exercise routine. Baseline physiological and exercise measurements …
