Abstract:
The spectrum of modern horse populations encompasses populations with a long history of development in isolation and relatively recently formed types. To increase our understanding of the evolutionary history and provide information on how to optimally conserve or improve these populations with varying development and background for the future, we analyzed genotype data of 184 horses from 9 Dutch or common horse populations in the Netherlands: The Belgian draft horse, Friesian horse, Shetland pony, Icelandic horse, Gelder horse, Groninger horse, harness horse, KWPN sport horse and the Lipizzaner horse population. Various parameters were estimated (e.g., runs of homozygosity and FST values) to gain insight into genetic diversity and relationships within and among these populations. The identified genomic makeup and quantified relationships did mostly conform to the development of these populations as well as past and current breeding practices. In general, populations that allow gene-flow showed less inbreeding and homozygosity. Also, recent bottlenecks (e.g., related to high selective pressure) caused a larger contribution of long ROHs to inbreeding. Maintaining genetic diversity through tailor-made breeding practices is crucial for a healthy continuation of the investigated, mostly inbred and (effectively) small sized horse populations, of which several already experience inbreeding related issues.

Abstract:
A 13-year-old Friesian stallion was referred for evaluation of acute coughing and bilateral nasal discharge. Thoracic radiographs revealed dilation of the terminal portion of the oesophagus, forming a thin-walled outpouching containing soft tissue opaque material and gas. A diagnosis of oesophageal obstruction with an impacted diverticulum was made. Caudal oesophageal muscularis hypertrophy and an impacted oesophageal diverticulum were found on postmortem examination. Histological abnormalities included a thick caudal oesophageal tunica muscularis and an oesophageal diverticulum composed of mucosa, submucosa and adventitia. Muscular hypertrophy of the oesophagus with diverticulum formation should be considered in Friesian horses presenting with clinical signs of oesophageal obstruction. In this case, thoracic radiographs contributed to a premortem diagnosis, guided medical management and provided information on prognosis. Thoracic radiography can be used as a complementary test in the diagnosis of oesophageal obstruction when endoscopy is available and is a useful diagnostic alternative when endoscopy is not an option.

Abstract:
In this report, a ten-year-old gelding with immune-mediated hemolytic anemia associated with chronic fibrosing mediastinitis of unknown origin is described. The patient suffered from chronic weight loss and intermittent diarrhea for already several months. He was presented with severe anemia, anorexia and fever of a 24-hour onset. A direct Coombs test was highly positive for IgG auto-agglutination. No evidence of an underlying process was found on clinical examination. Post-mortem examination revealed green liquid material containing food particles in the cranial mediastinum and histology suggested chronic fibrosing mediastinitis. Even though perforation of the esophagus is a plausible cause, no signs of esophageal rupture were noted on macroscopic examination. This case shows that non-responsive, immune-mediated hemolytic anemia can be due to an undetected underlying disease, such as chronic mediastinitis.

Full text
Abstract:
Based on a data set comprising 2879 animals and 17 nuclear microsatellite DNA markers, we propose the most comprehensive in-depth study mapping the genetic structure and specifying the assignment success rates in horse breeds at the Czech population scale. The STRUCTURE program was used to perform systematic Bayesian clustering via the Markov chain Monte Carlo estimation, enabling us to explain the population stratification and to identify genetic structure patterns within breeds worldwide. In total, 182 different alleles were found over all the populations and markers, with the mean number of 10.7 alleles per locus. The expected heterozygosity ranged from 0.459 (Friesian) to 0.775 (Welsh Part Bred), and the average level reached 0.721. The average observed heterozygosity corresponded to 0.709, with the highest value detected in the Czech Sport Pony (0.775). The largest number of private alleles was found in Equus przewalskii. The population inbreeding coefficient F<sub>IS</sub> ranged from –0.08 in the Merens to 0.14 in the Belgian Warmblood. The total within-population inbreeding coefficient was estimated to be moderate. As expected, very large genetic differentiation and small gene flow were established between the Friesian and Equus przewalskii (F<sub>ST </sub>= 0.37, Nm = 0.43). Zero F<sub>ST</sub> values indicated no differences between the Czech Warmblood–Slovak Warmblood and the Czech Warmblood–Bavarian Warmblood. A high level of breeding and connectivity was revealed between the Slovak Warmblood–Bavarian Warmblood, Dutch Warmblood–Oldenburg Horse, Bavarian Warmblood–Dutch Warmblood, and Bavarian Warmblood–Oldenburg Horse. The breeds’ contribution equalled about 6% of the total genetic variability. The overall proportion of individuals correctly assigned to a population corresponded to 82.4%. The posterior Bayesian approach revealed a hierarchical dynamic genetic structure in four clusters (hot-blooded, warm-blooded, cold-blooded, and pony). While most of the populations were genetically distinct from each other and well-arranged with solid breed structures, some of the entire sets showed signs of admixture and/or fragmentation.

Abstract:
Equine bioenergetics have predominantly been studied focusing on glycogen and fatty acids. Combining omics with conventional techniques allows for an integrative approach to broadly explore and identify important biomolecules. Friesian horses were aquatrained (n = 5) or dry treadmill trained (n = 7) (8 weeks) and monitored for: evolution of muscle diameter in response to aquatraining and dry treadmill training, fiber type composition and fiber cross-sectional area of the M. pectoralis, M. vastus lateralis and M. semitendinosus and untargeted metabolomics of the M. pectoralis and M. vastus lateralis in response to dry treadmill training. Aquatraining was superior to dry treadmill training to increase muscle diameter in the hindquarters, with maximum effect after 4 weeks. After dry treadmill training, the M. pectoralis showed increased muscle diameter, more type I fibers, decreased fiber mean cross sectional area, and an upregulated oxidative metabolic profile: increased β-oxidation (key metabolites: decreased long chain fatty acids and increased long chain acylcarnitines), TCA activity (intermediates including succinyl-carnitine and 2-methylcitrate), amino acid metabolism (glutamine, aromatic amino acids, serine, urea cycle metabolites such as proline, arginine and ornithine) and xenobiotic metabolism (especially p-cresol glucuronide). The M. vastus lateralis expanded its fast twitch profile, with decreased muscle diameter, type I fibers and an upregulation of glycolytic and pentose phosphate pathway activity, and increased branched-chain and aromatic amino acid metabolism (cis-urocanate, carnosine, homocarnosine, tyrosine, tryptophan, p-cresol-glucuronide, serine, methionine, cysteine, proline and ornithine). Trained Friesians showed increased collagen and elastin turn-over. Results show that branched-chain amino acids, aromatic amino acids and microbiome-derived xenobiotics need further study in horses. They feed the TCA cycle at steps further downstream from acetyl CoA and most likely, they are oxidized in type IIA fibers, the predominant fiber type of the horse. These study results underline the importance of reviewing existing paradigms on equine bioenergetics.

Abstract:
Transabdominal ultrasonography has been shown to be a useful and reliable method for assessing fetal well-being in horses and cattle. To test the applicability of fetal aortic diameter measurement in cattle, 44 late-term pregnant cows and heifers were examined 21 to 0 days prior to calving. Mean fetal aortic diameter was 2.07 ± 0.14 cm and mean fetal heart rate (FHR) was 109 ± 17 bpm. Three dead calves were dissected and their aortic diameter was measured in a water bath. The mean birth weight (n = 44) was 39.9 ± 5.8 kg. There was a significant negative correlation between FHR and fetal aortic diameter. However, although some studies have shown that fetal aortic diameter strongly correlates with birth weight in near-term horses and cattle, in this study there was no correlation between fetal aortic diameter and birth weight in Holstein-Friesian cows and heifers irrespective of whether the fetus was born alive or dead.

Full text
Abstract:
There is a notable lack of reference values for the renal resistive indices in the bovine kidney. Ultrasound (US) Doppler evaluation of these indices is a powerful, non-invasive technique for assessing, monitoring and diagnosing renal diseases in humans and other animals (e.g., small animals and horses). The aims of the present study were to establish a protocol for renal Doppler US in adult healthy Holstein-Friesian cows and to provide reference values for the renal resistive index (RI) and pulsatility index (PI). In cattle, the right kidney is always visible through a right abdominal window. Nevertheless, the left kidney is rarely accessible by transabdominal ultrasound. Doppler evaluation of the kidneys via a transabdominal approach is possible when accessible, but measurements can only be made in the larger vessels at the renal hilum. Normal RI and PI values were respectively 0.49 ± 0.07 and 0.70 ± 0.15 for the right kidney and 0.53 ± 0.05 and 0.79 ± 0.11 for the left kidney. We suggest an upper cut-off value for the RI of 0.63 and for the PI of 1.00 in healthy Holstein-Friesian cows. This is the first report describing normal values for the renal RI and PI in cattle that may be useful in future studies for characterizing different bovine pathologies that affect the renal parenchyma.

Abstract:
The term dystocia refers to an abnormal birth and the most common cause is an abnormal alignment of the head or forelimbs in the birth canal. Usually in adult horses, acute renal failure occurs as a complication of another disease process that causes hypovolemia . Diarrhea and severe laminitis may develop in more serious cases. The aim of this case report was to present a cesarean section in the mare that evolved with renal failure and subsequent with laminitis. A nine year old Friesian mare was referred to the Veterinary teaching hospital FMV Cluj-Napoca, after a dystocia that could not be resolved conservatively.During surgery, profuse hemorrhage was noticed during the incision and suture of the uterine wall. Hypovolemia was corrected and recovery was uneventful. Two days after surgery, the mare developed acute hyposthenuric renal failure. After 3 days of intensive therapy, kidney function started to improve but the mare developed laminitis. The mare improved over a few weeks and was discharged after orthopedic shoeing. According to the author’s knowledge, this is the first case report of a cesarean section in the mare that evolved into this cascade of sequelae.

Abstract:
Abstract Rocinela dumerilii (Lucas, 1849) is obtained on the horse mackerel, Trachurus trachurus (Linnaeus, 1758) from the Sea of Marmara, in Turkey. This species is a free-living organism from the Aegean Sea of Turkey, the Mediterranean Sea and Atlantic. Its micropredator behaviour is discovered for the first time in this study. Elthusa sinuata (Koelbel, 1879) is also collected on the gill cavity of Fries’s goby, Lesueurigobius friesii (Malm, 1874) in this study. This host is a new record for Elthusa sinuata. The morphological characters of Rocinela dumerilii species are given by drawings.

Abstract:
AbstractA herd of high-yielding Friesian dairy cows was observed outdoors and in a modern cubicle house. Indoors there was a much higher level of gross agonistic behaviour than at pasture (9·5 v. 1·1 per h). Furthermore, the use of continuous filming showed a high level of avoidance amongst the cows which impeded the movement of the more submissive cows. All cows spent proportionately 0·34 to 0·56 of their time indoors watching one another and 0·45 to 0·66 of their time in ‘social tension’. There was less synchrony of behaviour indoors than at pasture and despite the presence of one Calan Broadbent stall for each cow there was a high rate of displacement from the stalls involving cows of all degrees of dominance. The results are discussed in relation to housing design and husbandry practice.

Abstract:
Information regarding bone mineral density and fracture characteristics of the equine metacarpus are lacking. The aim of this study was to characterize the relationship between mechanical properties of the equine metacarpal bone and its biomechanical and morphometric properties. Third metacarpal bones were extracted from horses euthanized unrelated to musculoskeletal conditions. In total, bone specimens from 26 front limbs of 13 horses (7.8 ± 5.8 years old) including Lipizzaner (n = 5), Hungarian Warmblood (n = 2), Holsteiner (n = 2), Thoroughbred (n = 1), Hungarian Sporthorse (n = 1), Friesian (n = 1), and Shagya Arabian (n = 1) were collected. The horses included 7 mares, 4 stallions and 2 geldings. Assessment of the bone mineral density of the whole bone across four specific regions of interest was performed using dual-energy X-ray absorptiometry. The bones were scanned using a computer tomographic scanner to measure cross-sectional morphometric properties such as bone mineral density and cross-sectional dimensions including cortical area and cortical width. Mechanical properties (breaking force, bending strength, elastic modulus) were determined by a 3-point bending test. Significant positive linear correlations were found between the breaking force and bone mineral density of the entire third metacarpal bones (P < 0.001, r = 0.72), the medial cortex region of interest (P < 0.001, r = 0.68) and the transverse region of interest (P < 0.001, r = 0.61). The correlation between the breaking force and bone mineral density of the equine third metacarpal bone found in this study warrants in vivo investigations.

Abstract:
Purpose This paper aims to examine the existence of the ripple effect from Amsterdam to the housing markets of other regions in The Netherlands. It identifies which regional housing markets are influenced by house price movements in Amsterdam. Design/methodology/approach The paper considers the ripple effect as a lead-lag effect and a long-run convergence between the Amsterdam and regional house prices. Using the real house prices for second-hand owner-occupied dwellings from 1995q1 to 2016q2, the paper adopts the Toda–Yamamoto Granger Causality approach to study the lead-lag effects. It uses the autoregressive distributed lags (ARDL)-Bounds cointegration techniques to examine the long-run convergence between the regional and the Amsterdam house prices. The paper controls for house price fundamentals to eliminate possible confounding effects of common shocks. Findings The cumulative evidence suggests that Amsterdam house prices have influence on (or ripple to) all the Dutch regions, except one. In particular, the Granger Causality test concludes that a lead-lag effect of house prices exists from Amsterdam to all the regions, apart from Zeeland. The cointegration test shows evidence of a long-convergence between Amsterdam house prices and six regions: Friesland, Groningen, Limburg, Overijssel, Utrecht and Zuid-Holland. Research limitations/implications The paper adopts an econometric approach to examine the Amsterdam ripple effect. More sophisticated economic models that consider the asymmetric properties of house prices and the patterns of interregional socio-economic activities into the modelling approach are recommended for further investigation. Originality/value This paper focuses on The Netherlands for which the ripple effect has not yet been researched to the authors’ knowledge. Given the substantial wealth effects associated with house price changes that may shape economic activity through consumption, evidence for ripples may be helpful to policy makers for uncovering trends that have implications for the entire economy. Moreover, the analysis controls for common house price fundamentals which most previous papers ignored.

Abstract:
Rearing entire male calves for beef is becoming more common, but there is concern that sexual behaviour among bulls may be economically damaging and that there may be aggression between bulls and against stockmen. Behaviour has only been studied in detail in mature bulls or under disturbed conditions.To compare the development of behaviour in stable groups of Friesian-Holstein bulls and steers prior to sale at one year old, and to assess implications for management.Twelve bulls and 12 steers were held in an open-sided house at 5 m2/calf, with2 ad libitum hay, concentrates and water. From 5 to 10 months old, each calf was observed for one hour each month and all sexual and aggressive interactions between calves were recorded. At 6½ months, the pen was divided into halves, separating bulls and steers. This reduced the frequency of all interactions. At 10 months, reaction to humans was assessed on a scale from 1 (approach strongly) to 5 (avoid strongly). Bulls and steers were compared on all measures by the Mann-Whitney non-parametric statistical test (* = P < 0.05, ** - P <0.01).

Abstract:
An 8-year-old Friesen mare was admitted to the Equine Clinic, University of Veterinary and Pharmaceutical Sciences, Brno, Czech Republic with ventral edema and weight loss which had proceeded over the course of a few weeks. Clinical examination revealed poor body condition, depression, weakness, pale mucous membranes, enlarged mandibular lymph nodes and ventral edema. Thoracic percussion revealed fluid level reaching the shoulder on both sides. CBC revealed a severe disproportion of red and white cells. The horse was anemic and there was leucocytosis with the majority being blast cells (leucocyte concentration was 450.4 × 10<sup>9</sup>/l) which included mitotic figures. The serum chemistry profile revealed hypoalbuminemia and increased alkaline phosphatase bone isoenzyme (BALP was 784.3 &mu;kat/l). Based on the number of precursors in the peripheral blood acute leukemia was diagnosed. The peripheral blood was examined by flow cytometry and cytochemistry. The final diagnosis was determined as acute B cell lymphoid leukemia. The mare was treated with corticosteroids. On the second day of treatment the white blood cell count and alkaline phosphatase level decreased. The improvement continued until the fifth day, when the mare’s status deteriorated and the horse was euthanized. Gross examination was carried out but no neoplastic mass was discovered. Final differentiation between primary and secondary lymphoid leukemia was not possible in this case.
