Turkish Journal of Veterinary & Animal Sciences

The exercise-induced variations of some biochemical parameters including calcium (Ca), phosphorous (P), iron (Fe), copper (Cu), manganese (Mn), selenium (Se), zinc (Zn), sodium (Na), potassium (K), chlorine (Cl), glucose, urea, creatinine, lactate dehydrogenase (LDH), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and creatine kinase (CK) were assessed in the serum of 25 Arabian horses. Blood samples were taken from the jugular vein 3 different times: before exercise, 5 h after exercise, and 18 h after exercise. Statistical analysis was performed using SAS (version 9.2; SAS Institute, Cary, NC, USA). Ca, Cl, glucose, and urea showed significant (P < 0.05) changes due to exercise. There was significant increase from before exercise to 5 h after exercise in urea concentrations while Ca and Cl concentrations significantly decreased. A significant ascending trend for Ca between 5 h and 18 h after exercise was also seen, while glucose and urea had a significantly descending trend. No significant time-based variations were observed for other variables. The results of the present study indicated that exercise could affect the value of some biochemical parameters, which could be used in future studies evaluating the health status of Arabian horses.

Spatial Structuring Of Zooplankton Communities Through Partitioning Of Habitat And Resources In The Bay Of Bengal During Spring Intermonsoon, Veronica Fernandes, Nagappa Ramaiah

Turkish Journal of Zoology

Despite advances in oceanographic investigations in the Indian Ocean, zooplankton ecology is still poorly known from the open waters of the Bay of Bengal. In order to understand the vertical and horizontal distribution of zooplankton in the Bay of Bengal during spring intermonsoon, stratified sampling was conducted using a multiple plankton net. We found that higher zooplankton biomass was often associated with mesoscale cold-core eddies. The biomass in the mixed layer was less in the central bay and the near absence of organisms beneath this layer was attributed to the very low dissolved oxygen levels, including suboxia in the northern …

Turkish Journal of Veterinary & Animal Sciences

A new attempt was undertaken to check the reproductive capabilities of male hybrids bred from European bison (Bison bonasus) and domestic cattle (Bos taurus). The analysis concerned two hybrids aged 1.5?2.5 years (the latter being sampled twice at 6-month intervals), and additionally one 1.5-year-old backcross hybrid. Examination of testicular tissue revealed halting of spermatogenesis, which was hardly ever able to proceed further than meiosis I. Spermatogenesis was arrested at the stage of spermatogonia and primary spermatocytes. Spermatozoa were found only in the case of one hybrid and these were mostly malformed. To summarize, all the males studied were sterile, despite …

Chemical Composition And In Vitro Rumen Fermentation Of Ensiled Sugar Industry Coproducts, Zohreh Zarnegar, Seyed Hadi Ebrahimi, Abbas Ali Naserian, Reza Valizadeh

Turkish Journal of Veterinary & Animal Sciences

he current study aims to compare sugar beet leaves (SBLs) ensiled with sugar beet pulp (SBP), sugarcane molasses (SM), or rock candy juice (RCJ) using an in vitro gas production technique. Treatments in the first group included 10% SBP (control 1) and control 1 plus 5% SM or RCJ. In the second group, there were 3 treatments, including 20% SBP (control 2) and control 2 plus 10% SM or RCJ. The silages with no added soluble carbohydrate (SC) sources had significantly higher (P < 0.001) pH, buffer value index, and ammonia nitrogen values than the other treatments. However, there was no significant difference between RCJ and SM in their effect on these variables. Adding both levels of SC sources caused an increase in dry matter digestibility compared to those that only included SBL and SBP (P < 0.001). Maximal and rate of gas production from slowly fermentable fraction (a$_{2}$) were significantly greater when the substrate contained 85%, 10%, and 5% SBL, SBP, and SC sources, respectively. Using dried SBP and SC sources for the preservation of fresh SBL is recommended; however, with higher levels of SC, the silage may be at risk of spoilage, and it must be less exposed to air.

All Peer-Reviewed Publications

The perception of key players in the fish farming sector towards the use of insects is important for their acceptance to adopt insects as an alternative protein source to the expensive fish meal. Perception was established through a cross-sectional study of 208 fish farmers and 71 fish feed traders and/or processors conducted in Gulu, Tororo and Masaka districts in Uganda, using descriptive, Chi-square, correlation and factor statistical analysis of the data collected. Males dominated the fish farming and fish feed trading and/or processing enterprises. Youths were involved to almost the same extent as adults. Fish farmers majorly practiced pond fish …

Improving Broiler Performance Utilizing Modern Feed Additives, Niles Rourke Ridgeway

Graduate Theses, Dissertations, and Problem Reports (ETD)

Modern broiler production strives to make modest improvements regarding broiler performance. This remains a goal as global population increases thusly increasing the quantity of an affordable, high quality source of protein. In recent years, an added stressor to achieving prior goals is mostly related to consciousness of environmental and consumer health. For decades, integrators have utilized minimal amounts of antibiotics as a barrier to most pathogens affecting the microbiome of a broiler’s gastrointestinal tract. Regulatory efforts have now prohibited most of previous sub-therapeutic medicine and started an in-depth scope of broiler gut health and interaction with antibiotic alternatives. In an …

Happy Or Hangry Families: Does Kinship Mediate Cooperation And Cannibalism In Drosophila Melanogaster Larvae?, Lucas Khodaei

Theses and Dissertations (Comprehensive)

The fruit fly Drosophila melanogaster has a long history as a research model for studies on behaviour and group dynamics. When individuals are grouped in an environment and resources decrease, then they may behave co-operatively with one another or antagonistically compete. Hamilton’s Law states that if the benefit of helping a related individual out-weighs the cost to its direct fitness, then the individual’s indirect fitness will increase when they help their kin compared to helping an unrelated stranger. Yet it is unknown whether kinship mediates larval behaviour to encourage co-operation and/or lessen antagonistic behaviours between consanguineous individuals. In this thesis …

Publications and Research

Larus gull species have proven adaptable to urbanization and due to their generalist feeding behaviors, they provide useful opportunities to study how urban environments impact foraging behavior and host-associated microbiota. We evaluated how urbanization influenced the foraging behavior and microbiome characteristics of breeding herring gulls (Larus argentatus) at three different colonies on the east coast of the United States. Study colonies represented high, medium and low degrees of urbanization, respectively. At all colonies, gulls frequently foraged at landfills and in other urban environments, but both the use of urban environments and gull foraging metrics differed with the degree of urbanization. …

Optimization Of Light Irradiance During The Early Life Of Sexually-Produced Porites Astreoides And Agaricia Agaricites Recruits, Nicholas J. Mcmahon

HCNSO Student Theses and Dissertations

Current solutions of coral restoration rely mainly on fragmentation. Though a reliable technique, this asexual form of reproduction does not benefit the genetic diversity of the coral reef. With many global and local stressors threatening corals’ existence, the resiliency of corals to future ocean conditions depends highly on sexual reproduction to produce new genotypes. New technology allows coral spawning/larval release, larval settlement and rearing to be carried out in an aquarium system. Many of the techniques necessary to maintain coral recruits are well-established, however the effects of light intensity remain to be studied for these early life stages. Newly …

Consumer Perceptions Of Labeling Claims On Poultry Products, Sarah Townley

Agricultural Education, Communications and Technology Undergraduate Honors Theses

An increasing number of consumers wants more knowledge of how the food they eat is produced, and specifically, how animals used in the production of their food are raised. One method consumers use to become more aware of production practices behind the food they purchase and consume is simply reading food labels. Labeling claims can be defined as textual, pictorial, graphic, or symbolic representation that either explicitly states or implies that a food product has a specific set of properties supported by a certification process. The purpose of this study is to gather data regarding consumer knowledge and understanding of …
