Camel welfare: survey on camel caretakers' perspectives

Animal welfare depends on caretakers' handling and management skills. The study aimed at gaining information on camel caretakers' backgrounds, their perceptions of welfare and management practices and at investigating associations with camel health and behavioural problems. The study was conducted at a camel market in Qatar and 49 caretakers were interviewed (29 questions). Caretakers were male, mainly from Sudan (91.7%; P<0.001), and had mainly learned camel management from family members (81.6%; P<0.001). Camels were mainly from Qatar, reared for milk, breeding or meat. The majority of the caretakers under 30 years took care of camels reared as breeding animals or for milk production (n=12, 75.0%), while the caretakers over 40 years took care of camels for dual-purposes (n=7, 46.7%; P<0.05) or meat (n=4, 26.7%). Camels received rationed feed and water (87.6%, 53.1%, P<0.001), and were dewormed regularly (96.8%, P<0.001) but not vaccinated (72.9%; P<0.001). Respondents experienced at least one camel with a behavioural (45.8%) and a health (87.8%) problem and associations between management practices and those problems were found. Behavioural problems were associated with the number of health problems, suggesting that sick camels tended to show behavioural modifications. Caretakers ranked their ability to recognise a camel in distress/pain as high, reporting that the first sign was a change in behaviour. The caretakers' understanding of animal welfare was, however, low, missing the overall meaning of the concept; most caretakers defined animal welfare according to only one (52.2%) welfare principle. Overall, early and appropriate treatment of camels with health and behavioural problems, an increased presence of veterinarians at camel farms, and education on camel behaviour and welfare are recommended

Predictive Value of Acute Phase Proteins for the Short-Term Outcome of Meningoencephalitis of Unknown Origin in Dogs

Meningoencephalitis of unknown origin (MUO) is one of the most common inflammatory diseases of the central nervous system (CNS). The study evaluates the possible increase and the potential role of acute phase proteins (APPs) and other inflammatory serum parameters as biomarkers predicting the short-term outcome of dogs with meningoencephalitis of unknown origin (MUO). A retrospective cohort study was designed. The APP profile and other markers of systemic inflammation of forty-eight client-owned dogs with a new diagnosis of MUO were compared between 7-day survival and non-survival dogs diagnosed with MUO. Thirty-nine (81%) dogs were alive at the end of the 7-day follow-up period, while 9 (19%) dogs died or were euthanized because of MUO. None of the 11 markers of inflammation studied were different between the survived and non-survived dogs; for this reason, none of them could be used as a predictor of the short-term outcome based on the results of the present study. This confirms that even though MUO is often associated with a severe inflammatory status of the central nervous system (CNS), this condition is probably isolated exclusively to the CNS

Gonadectomy in Raccoons: Anesthetic and Cardiorespiratory Effects of Two Ketamine-Based Pre-Anesthetic Protocols before Sevoflurane-Sufentanil

Nineteen raccoons were enrolled in this study. The aim was to evaluate and compare the quality of anesthesia and the cardiorespiratory eects following treatment with a ketamine-based combination with either dexmedetomidine (KD group) or midazolam (KM group) in raccoons undergoing ovariohysterectomy/orchiectomy. General anesthesia was maintained with sevoflurane in oxygen and sufentanil infusion. The time required to approach the animals was similar among groups resulting in a median of 5 min after IM injection. Animals in group KD were scored with greater myorelaxation (p < 0.01) and easier intubation (p < 0.05). Moreover 70% of them did not require other drugs for tracheal intubation unlike animals in group KM, which required propofol in 100% of cases. After intubation and connection to the breathing circuit, physiological parameters were monitored continuously and recorded every 5 min. Sevoflurane requirements were lower in group KD than KM (p = 0.005). Blood pressure was maintained within physiological ranges in both groups but with higher values in group KM (p < 0.05). Mild respiratory depression occurred during surgery and animals in group KM showed greater respiratory acidosis (p < 0.05). Recovery was smooth and uneventful in all animals. Both anesthetic protocols can be recommended for safe anesthesia in wild raccoons

Transport certifications of cattle moved from France to Southern Italy and Greece: do they comply with Reg. EC 1/2005?

Movements of livestock across the Member States is monitored using the Trade Control and Expert System (TRACES), a web-based veterinarian certification tool. This study aimed to evaluate the criticalities of this tracing system and the most frequent non-conformities in their compilation. TRACES of cattle (n = 320) departed from France and arriving or transiting across Puglia (Italy) in 2019 (n = 199) and 2020 (n = 121) were analysed. The distribution arriving in Italy and Greece did not vary between the 2 years. The majority of the bovine (53.4%) were medium-sized cattle transported for fattening with a median body weight of 410 kg. However, almost half of the TRACES did not report correctly the total expected loaded weight or the available space, so for them, it was impossible to calculate and double-check whether the minimal space allowance was respected. Long journeys must include a resting stop after the first 14 h, however, 20.9% of the examined and declared stops did not comply with it. Finally, comparing the expected declared journey duration with a calculated one (dividing travel distance by an average speed of 70 km/h, adding 1 h for loading and unloading, and 1 h or 24 h for resting stops), we found that only 30.6% of the journey durations were congruent. The irregularities resulted associated with consignors and transporters (p < .05). Overall, the proportion of mistakes and non-compliance suggest that there is a need to improve the current practice to enhance animal welfare during transportation

Benefits of dietary supplements on the physical fitness of German Shepherd dogs during a drug detection training course

A high standard of physical fitness is an essential characteristic of drug detection dogs because it affects not only their ability to sustain high activity levels but also their attention and olfaction efficiency. Nutritional supplements could improve physical fitness by modulating energy metabolism, oxidative processes, and perceived fatigue. The aim of this study was to investigate the physiological and biochemical changes induced by submaximal exercise on drug detection dogs (German Shepherd breed) and to assess whether a dietary supplement improves their physical fitness. During a drug detection dog training course, seven dogs were fed with a basal diet (Control Group) for three-month period, while a further seven dogs were fed with a basal diet as well as a daily nutritional supplement containing branched-chain and limiting amino acids, carnitine, vitamins, and octacosanol (Treatment Group). At the end of this period, individual physical fitness was assessed by making each subject take a graded treadmill exercise test. A human heart rate monitor system was used to record the dog's heart rate (HR) during the treadmill exercise and the subsequent recovery period. The parameters related to HR were analysed using nonparametric statistics. Blood samples were collected before starting the nutritional supplement treatment, before and after the treadmill exercise and following recovery. Linear mixed models were used. The dietary supplements accelerated HR recovery, as demonstrated by the lower HR after recovery (P<0.05) and Time constants of HR decay (P<0.05), and by the higher Absolute HR Recovered (P<0.05) recorded in the Treatment group compared with the Control dogs. The supplemented dogs showed the lowest concentrations of creatine kinase (CK; P<0.001), aspartate aminotransferase (AST, P<0.05) and non-esterified fatty acids (NEFA; P<0.01) suggesting a reduction in muscle damage and improvement of energy metabolism. These data suggest that this combined supplement can significantly enhance the physical fitness of drug detection dogs

An innovative tool for assessing welfare of camels

Whilst there are many tools for the assessment of welfare in livestock, there is none for camels. This study aimed therefore to pilot a method for assessing the welfare status of camels using animal-, resource- and management-based indicators at a camel market in Qatar. Adapting the AWIN protocol, data related to housing, feeding, health, and behaviour were collected at three levels: caretaker, herd, and animal. The Caretaker level was an interview exploring the caretaker’s background, experience, and routine management practices. The Herd level was a check of the herd and of the place (i.e. box/pen) where camels were kept. At the Animal level, BCS, health, and behavioral parameters were recorded from 2 animals/pens, randomly selected. The number of animals/pens varied (average: 7, range: 1–37 animals) with a total population of 528 animals. The size of the pen was variable (26–256 m2), and consequently the space allowance varied from 2.5 to 34 m2/animal. The environmental temperature was high (average: 42 °C, range: 37–50 °C) and when in the paddock there was a shelter (86%) the camels moved into the shade (313/528 animals). In all paddock, there was a water point, but the water was often not available (22%), dirty (41%), or warm (max:42.9 °C); the majority of the camels therefore drunk when clean and fresh water was offered (bucket test latency time: median =8 sec, IQR =3–40 sec). BCS varied and was rarely optimal (median =2, IQR =2–3). Most of the animals (89%, p < .001) were free of movements (1% tied, 10% hobbled). However, many animals were not free from disease (38%), injuries (5%), scars (7%), and cauterization (38%). Skin diseases were the most common health problems (28%; p < .001), followed by respiratory diseases (4%). The majority of the animals showed a good human-animal relationship (friendly, 48%, or neutral, 30%, approach; p < .001), and no stereotypes were noted. However, some animals were aggressive (6%), when they were old, in pain (2%), or distressed (8%). The caretaker came mainly from Sudan (91%; p < .001), with experience in camel handling often learned by father-son tradition (82%; p < .001) and for many of them, animal welfare was ‘treat the animals gently, feeding and watering them’. This was a preliminary study to pilot a tool to assess welfare in camels; further studies are needed to validate this tool in other camel farms worldwide

No association between candidate genes for color determination and color phenotype in Hierophis viridiflavus, and characterization of a contact zone

Genetic and phenotypic differentiation in allopatric conditions can be explained either by neutral phenomena or adaptative processes driven by selection. In reptiles, coloration can affect aspects directly related to their survival, representing a classical character under selection. In this context, secondary contact areas are natural laboratory to understand evolutionary processes underlying genetic permeability, especially when populations differ in phenotypic traits such as coloration. The western whip snake Hierophis viridiflavus presents two divergent mitochondrial clades, characterized by the presence of one of two main color phenotypes, namely one with black and yellow stripes and a fully melanic one. Here, we investigated whether melanogenesis-linked genes are determinant of the chromatic differences observed across the phenotypic variation of the species. In addition, we used a multilocus dataset, including 134 original ND4 sequences, to better define the overall genetic structure and to provide a characterization of a contact zone identified in Central Italy by estimating the amount of nuclear gene exchange. While we found no evidence supporting a direct association between target genes and coloration, a non-synonymous substitution polymorphism, at high frequency, was detected in the β melanocyte-stimulating hormone whose possible function has been discussed. Concerning the genetic structure, both mtDNA and nuDNA were partly concordant indicating introgression events occurring at the contact zone. When we measured the nuclear gene flow, we found a significant amount of gene exchange, mainly guided from one clade to the other, that is, asymmetric. These results might suggest the presence of ecological and/or behavioral processes driving the observed directional gene flow
