Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to investigate the effects of the use of Theranekron alone or in combination with intramammary antibiotic therapy for the treatment of subclinical and clinical mastitis on the recovery rate from mastitis. The study material was composed of 177 mammary lobes of 63 Holstein cows with subclinical (groups S1 and S2) and clinical mastitis (groups C1, C2, C3, and C4). In all of the treatment groups, excluding group S2, the California mastitis test scores were determined to have decreased after treatment (P < 0.05). In groups C1, C2, C3, and C4, which were treated for clinical mastitis, the somatic cell count (SCC) values were observed to have decreased. The decrease in SCC values was statistically significant except in group C2 (P < 0.01). While the SCC values were observed to have decreased in group S1 (P > 0.05), which was treated with Theranekron alone, the same values were found to …

Consuming Fire Ants Reduces Northern Bobwhite Survival And Weight Gain, P. Evans Myers, Craig R. Allen, Hannah E. Birge Jan 2014

Consuming Fire Ants Reduces Northern Bobwhite Survival And Weight Gain, P. Evans Myers, Craig R. Allen, Hannah E. Birge

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Northern bobwhite quail, Colinus virginianus (L.) (Galliformes: Odontophoridae), population declines are well documented, but pinpointing the reasons for these decreases has proven elusive. Bobwhite population declines are attributed primarily to loss of habitat and land use changes. This, however, does not entirely explain population declines in areas intensively managed for bobwhites. Although previous research demonstrates the negative impact of red imported fire ant (Solenopsis invicta Buren) (Hymenoptera: Formicidae) on northern bobwhites, the mechanisms underlying this effect are largely unknown. To meet the protein demands of early growth and development, bobwhite chicks predominantly consume small insects, of which ants are …

Interaction Of Isoflavones And Endophyte-Infected Tall Fescue Seed Extract On Vasoactivity Of Bovine Mesenteric Vasculature, Yang Jia Jan 2014

Interaction Of Isoflavones And Endophyte-Infected Tall Fescue Seed Extract On Vasoactivity Of Bovine Mesenteric Vasculature, Yang Jia

Theses and Dissertations--Animal and Food Sciences

Endophyte-infected tall fescue produces many ergot alkaloids, which have been shown to be vasoconstrictive in various vessel types of bovine. On the other hand, substantial evidence has been reported on the vasodilative effects of formononetin and biochanin A in different vessel types in humans and rats. So, a study was conducted using mesenteric vasculature collected from heifers shortly after slaughter. After 2-h incubation with formononetin (F), biochanin A (B), or an ergovaline-containing tall fescue seed extract (EXT) and their combinations, vessels were mounted in a multi-myograph to determine their ergotamine-induced contractility. Results indicated that F and B at 1 × …

Effect Of Direct-Fed Microbials And Monensin On In Vitro Rumen Fermentation, Sheryl Wingard Jan 2014

Effect Of Direct-Fed Microbials And Monensin On In Vitro Rumen Fermentation, Sheryl Wingard

Theses and Dissertations--Animal and Food Sciences

The impact of supplying a mixed culture of lactate producing bacteria on in-vitro rumen fermentation of forage- (Experiment 1) and concentrate- (Experiment 2) based diets in the presence and absence of monensin was explored. In experiment 1, interactions between DFM and MON were absent (P>0.10) for gas production and fermentative end products. Gas production and fermentative end products were unaffected by DFM alone (P>0.10). Monensin decreased (P<0.001) CH4 and NH3 production, rate and total gas production, as well as total VFA concentration and molar proportions of acetate and butyrate. However, MON increased (P<0.001) proportions of propionate, valerate, isobutyrate and isovalerate. Independently, DFM and MON increased (P<0.001) end point pH. In experiment 2, DFM x MON interactions or tendencies (P=0.07, P<0.01, P<0.01) were present, DFM effects were abated by MON, for rate, total gas production and total VFA concentrations. Acetate:propionate ratio was decreased (P<0.01) with MON and was unaffected by DFM. Ammonia-N concentration was increased (P<0.01) by DFM and unaffected (P=0.75) by MON. Both DFM and MON treatment increased (P<0.01) ruminal pH levels. These studies suggest the effects of DFM and MON of in-vitro fermentation are …

Evaluating Dietary Amino Acid Adequacy In Horses Using Isotopic Techniques, Sara L. Tanner Jan 2014

Evaluating Dietary Amino Acid Adequacy In Horses Using Isotopic Techniques, Sara L. Tanner

Theses and Dissertations--Animal and Food Sciences

Little is known about amino acid (AA) requirements in horses despite muscle mass accretion being of importance to an athletic species. Isotope methods for determining AA requirements and whole-body protein synthesis (WBPS) had not been previously used in growing horses. The first study herein was the first to apply isotope methods to determine WBPS in growing horses. In the study, weanling colts received two different levels of crude protein. Whole-body protein kinetics indicated that WBPS was greater when the weanlings were fed the diet with a greater crude protein content (P<0.05). The second study sought to determine a lysine requirement for yearling horses using the indicator AA oxidation (IAAO) method. Despite using six dietary levels of lysine; three above and three below the current recommendation, no breakpoint could be determined. Phenylalanine kinetics were not affected by lysine level (P>0.05), but plasma lysine increased linearly with lysine intake …

Comparison Of Long-Term Progestin-Based Synchronization Protocols On Fixed-Time Ai Pregnancy Rate In Beef Heifers, Rebecca A. Vraspir, Adam F. Summers, Doug O'Hare Hare, Larry D. Rowden, Rick N. Funston

Nebraska Beef Cattle Reports

Yearling Angus heifers at a commercial ranch in the Nebraska Sandhills were randomly assigned to one of two progestin-based fixed-time AI protocols (MGA or 14-day CIDR) to compare pregnancy rates. Heifers had similar fixed-time AI pregnancy rates between MGA and 14-day CIDR. A similar proportion of MGA and 14-day CIDR heifers displayed a second estrus; however, heifers previously synchronized with MGA tended to have a greater second AI pregnancy rate. Overall pregnancy rate was similar between MGA and 14-day CIDR treatments. The MGA system was the more cost effective synchronization protocol in this study.

Habitat Quality Influences Migratory Strategy Of Female White-Tailed Deer, Charles R. Henderson Jr. Jan 2014

Habitat Quality Influences Migratory Strategy Of Female White-Tailed Deer, Charles R. Henderson Jr.

Graduate Student Theses, Dissertations, & Professional Papers

Partial migration is a life history strategy that is common for ungulate species living in seasonal environments. One factor that influences the decision to migrate by ungulates is access to high quality habitat. We evaluated the influence of access to winter habitat of high quality on the probability of an individual migrating, the differences in seasonal habitat use between and within migratory and resident classes of deer, and the effects of this decision on the survival of female white-tailed deer. We hypothesized that deer with home ranges of relatively low quality in winter would have a relatively high probability of …

Evaluating The Effects Of Chitosan, Plant Oils, And Different Diets On Rumen Metabolism And Protozoan Population In Sheep, Monika Wencelova, Zora Varadyova, Katarina Mihalikova, Svetlana Kisidayova, Dusan Jalc Jan 2014

Evaluating The Effects Of Chitosan, Plant Oils, And Different Diets On Rumen Metabolism And Protozoan Population In Sheep, Monika Wencelova, Zora Varadyova, Katarina Mihalikova, Svetlana Kisidayova, Dusan Jalc

Turkish Journal of Veterinary & Animal Sciences

Chitosan (CH) has been shown to be a promising natural antimicrobial agent. This study examined the effects on rumen metabolism when providing diets containing high forage (HFD), low forage (LFD), and maize silage (MSD) to a 24-h batch culture in which the diets were not supplemented (control) or were supplemented with CH (100 mg/L), sunflower oil (SF, 35.0 g/kg dry matter), rapeseed oil (RP, 35.0 g/kg dry matter), or SF and RF with chitosan combinations (SFCH and RPCH). Dry matter digestibility in the batch culture was influenced by CH and was decreased in HFD compared with the control (P < 0.01). Decreasing total number of protozoa and the number of Entodinium spp. was evident, especially in LFD and MSD, with all additives. RPCH had a predominantly adverse effect on Dasytricha ruminantium in MSD. Interactions of the diets × additives in the majority of rumen ciliate populations were detected. The concentrations of trans-vaccenic acid and conjugated linoleic acid (c9, t11-CLA) were unchanged by chitosan. However, the combination of SF and RF with chitosan (SFCH and RPCH) positively affected fatty acid profiles, which might be related to differences in diets, SF or RP composition, and different microbial activity in the batch cultures.

Risk Factors For Postpartum Anestrus In Crossbred Cows In Bangladesh, Md Mostofa Kamal, Md Musharraf Uddin Bhuiyan, Nasreen Parveen, Harry W. Momont, Mohammed Shamsuddin Jan 2014

Risk Factors For Postpartum Anestrus In Crossbred Cows In Bangladesh, Md Mostofa Kamal, Md Musharraf Uddin Bhuiyan, Nasreen Parveen, Harry W. Momont, Mohammed Shamsuddin

Turkish Journal of Veterinary & Animal Sciences

Ultrasonography and a structured questionnaire were used in a cross-sectional study to gather data on the prevalence and risk factors for anestrus in crossbred cows at =>60 days postpartum in 273 smallholder farms. The prevalence of anestrus was 18%. The odds ratio (OR) for true anestrus was 17.52 and 2.81 times higher (P < 0.05) in cows with poor (=3.5) body condition score (BCS), respectively, compared to those with optimal BCS (2.5-3.5), 2.82 times higher in suckled than in nonsuckled cows (P = 0.03), and 2.53 times higher in cows that calved during the cold season than in those that calved during the hot season (P = 0.03). The OR for anestrus was 1.62 times higher (P = 0.017) in cows managed by an employee than in those managed by the farmers themselves (P = 0.001), and 2.66 times higher (P = 0.003) in small farms (=11 cows). The OR was 0.71 to 0.46 times lower in farms having a guaranteed market to sell milk than those with an uncertain traditional milk market (P < 0.05). Maintaining optimal BCS of cows, farmers' training on management of cattle reproduction, and development of a market linkage to sell milk would improve the number of cows for breeding by 60 days postpartum.

It was found that there is a cumulative impact of muscle and conformation class on intramuscular fat in blade muscle (P = 0.0330), as well as type of muscle and fat class (P = 0.0424), but there is no cumulative impact of conformation class and fat class (P = 0.1788). There is no cumulative influence of muscle type, conformation class, and fat class on amount of connective tissue in blade muscle, but …

Different levels of pomegranate peel extracted by either water (PEH) or solvent mixture (PEM) were evaluated for their effect on in vitro gas production and ruminal fermentation patterns. Two levels of PEH or PEM (15 and 30 mg total phenolics (TP)/g DM of basal diet) were compared to a control (0) level. Ruminal fermentation parameters such as 24-h partitioning factor (PF_{24}), gas yield (GY_{24}), in vitro organic matter disappearance (IVOMD), metabolizable energy (ME), and microbial protein (MP) were calculated. The addition of PEH or PEM had no effect (P > 0.05) on asymptotic gas production, apparent degraded substrate (ADS), IVOMD, ME, …
