Effect of diet composition on dry matter intake of dairy she-camels
AbstractThe present paper aims to propose an evaluation of the ingestibility and selectivity of food items, as well as the effect of different levels of energetic supplementation and concentrate feed ingredients, on camels dry matter intake (DMI). With this goal, an experiment on six dairy she-camels receiving every 14 –15 days a progressive high level of concentrates was conducted. During experimental periods, DMI ranged from 1.30 to 1.96 kg DMI per 100 kg of body weight (BW) was used. In an effort to examine the feeding behavior, a sign of reduced appetite was observed. Based on the results, it can b...

Genetic Characterization of Susceptible and Multi-Drug Resistant Mannheimia haemolytica Isolated from High-Risk Stocker Calves Prior to and After Antimicrobial Metaphylaxis
The objectives of the current study were to determine the genetic relationship between the isolates collected at arrival before metaphylaxis and at revaccination after metaphylaxis, to identify which resistance genes might be present in these isolates, and to determine if they were carried on an ICE. Twenty calves culture positive for Mh at arrival and revaccination were identified, and a total of 48 isolates with unique susceptibility profiles (26 from arrival, and 22 from revaccination) were submitted for whole-genome sequencing (WGS). A phylogenetic tree was constructed, showing the arrival isolates falling into four cl...

Targeted transcript analysis revealed association of suboptimal expression of certain endometrial immunity-related genes with disparate uterine diseases in zebu cows
AbstractThe onset of uterine infection during postpartum period compromises uterine health, fertility, and productivity of dairy cattle. Endometrial innate immunity plays a key role in eliminating uterine infection and keeping the uterus healthy. Hence, the present study has been designed with the hypothesis that altered endometrial immune response around calving may compromise uterine health during postpartum period.

AbstractMesenchymal stem cells (MSCs) are found in virtually all tissues, where they self-renew and differentiate into multiple cell types. Cumulative data indicate that MSCs secrete paracrine factors that may play key roles in the treatment of various acute and chronic pathological conditions in diverse animal species including cattle. The aim of the present study was to compare the potentials for proliferation, migration and pro-angiogenesis of bovine fetal BM-MSCs and AT-MSCs under in vitro conditions.

Efficiency Enhancement of Photocatalytic Degradation of Tetracycline using Reduced Graphene Oxide Coordinated Titania Nanoplatelet
This study focused on developing a low-cost catalyst to photodegrade TCH. Different formulations of TiO2 photocatalysts scaffolded with reduced graphene (denoted as TiO2-RGO-TiO2) were produced using a cost-effective sol-gel method. The mesoporous structured TiO2-RGO-TiO2 was tuned using citric acid as a complexing agent, Pluronic P-123 as a grafting agent and graphene oxide (GO) as structural “core” to guide the TiO2 growth. Our findings documented that the TiO2-RGO-TiO2 catalysts displayed high degradation efficiency towards TCH. This efficiency was determined to be improved by 22.8 % under ultraviolet light ...

Over the past decade, interventional oncology techniques have become integrated into the treatment plans of companion animals with cancer on a regular basis. Although procedures such as stenting are performed commonly, other less frequently utilized techniques for locoregional therapy, such as embolization and ablation, are emerging and demonstrating promise. Tumor ablation techniques are categorized into two subgroups: chemical ablation and energy-based ablation. Increased utilization of ablation will allow for the determination of specific indications and evaluation of outcomes for these techniques. (Source: Veterinary C...

Nodular lymphoid hyperplasia (NLH) is one of the most common non-neoplastic splenic lesions in dogs, especially in old ones, showing a splenic enlargement. More recent studies have been focused on Contrast Enh... (Source: BMC Veterinary Research)

Serology for Neosporosis, Q fever and Brucellosis to assess the cause of abortion in two dairy cattle herds in Ecuador
Determining the infectious cause of abortion in cattle is difficult. This case-control study was set up to investigate the infectious causes of abortion by determining the seroprevalence of three reproductive ... (Source: BMC Veterinary Research)

Pedobarography: a novel approach to test the efficacy of treatments for lameness; an experience with mavacoxib in dogs with elbow osteoarthritis
Pedobarographic analyses detect pressure redistribution among limbs and within limbs in humans, equids and dogs. The main objective of this study was to assess the usefulness of a set of pedobarographic parame... (Source: BMC Veterinary Research)

Semi-Mechanistic Modeling of Florfenicol Time-Kill Curves and in silico Dose Fractionation for Calf Respiratory Pathogens
An important application of time-kill curve (TKC) assays is determination of the nature of the best PK/PD index (fAUC/MIC or fT%>MIC) and its target value for predicting clinical efficacy in vivo. VetCAST (the veterinary subcommittee of EUCAST) herein presents semi-mechanistic TCK modeling for florfenicol, a long acting (96h) veterinary antimicrobial licensed against calf pneumonia organisms (Pasteurella multocida and Mannheimia haemolytica) to support justification of its PK/PDcut-off and clinical breakpoint. Individual TKC assays were performed with 6 field strains of each pathogen (initial inoculum 107 CFU/ml with s...

Association of bulk tank milk urea nitrogen concentration with elevated individual cow values and investigation of sampling frequency for accurate assessment
The objectives of the present study were to (a) predict the percentage of cows with elevated MUN within a herd using bulk tank (BTMUN) levels, in the absence of individual MUN records, and (b) establish a sampling freq uency protocol for the assessment of actual BTMUN levels. A database of 17,687 monthly individual MUN and concurrent 229 monthly BTMUN records from 24 dairy herds was used. A ROC analysis was performed to determine the BTMUN threshold over which cows in the herd have elevated MUN concentrations that , based on literature, affect fertility. Moreover, a regression was run to predict the percentage of cows with...
