Tannins are a diverse group of plant phenolic compounds. Condensed tannins (CTs) represent a major subgroup of tannins and were extracted from tilia (Tilia L.) flowers and black locust (Robinia pseudoacacia) leaves. These extracts were examined for their effects on the metabolic profile of chicken caeca. By using in vitro, a nuclear magnetic resonance (1H-NMR), which was combined with multivariate statistics, the current study was applied for the first time to investigate how three different CT compositions, procyanidins (PC) and/or prodelphinidins (PD) units influenced the metabolic end-products in caecal contents of chickens. In the presence of tannins, glutamate, leucine, lysine, pyroglutamate, phenylalanine, proline, and sarcosine were significantly decreased. CT extracts significantly influenced the fermentation, increasing the concentrations of some fatty acids such as acetate, butyrate, and propionate whereas. In contrast, lactate decreased between the treatments. This study identified the key structural features of CTs that contain either high molar proportions of PD or PC, which might be useful to improve the efficiency of feed utilization in chickens.

The industrial manufacturing of natural products for veterinary use represents a major weakness in the veterinary sector despite increased interest and the traditional ancestral knowledge that supports them. A cross-sectional, descriptive observational study was conducted to characterize the veterinary herbal products marketed worldwide during 2018 and 2019. A comprehensive thematic search limited to the 2018-2019 period was performed in the ScienceDirect, Scopus, PubMed, Web of Science, ResearchGate, and Academic Search Complete databases. The investigation identified 487 products registered in the global market manufactured by 54 companies, led by India, The Netherlands, and the United Kingdom. The market segments of animal production and phytomedicines were dominant with 73.7% and 53.0% of products, respectively. Cattle (22.2%), sheep-goats (16.2%), and canines (16.2%) were the most favored species. The most represented therapeutic indications were those intended to treat gastrointestinal disorders (30.47%), antimicrobials (16.66%), and antiparasitic agents (10.47%). The families Fabaceae, Lamiaceae, Asteraceae, Apiaceae, Malvaceae, and Rutaceae stood out because of their frequent use, encompassing 35.0% of the 137 declared species. Andrographis paniculata (Burm.f.) Nees and Withania somnifera (Lin) Dunal were the most important species. Oral formulations for internal use (72%) and liquids (51%) in 100 mL, 500 mL, and 1 L presentations showed the highest prevalence on the market. The global market for veterinary herbal products during the 2018-2019 period was relevant in the productive and medical animal sector. No differences were found between medicinal plant species used to formulate herbal products for human and animal use.

Afficher plus [+] Moins [-]Effect of egg yolk-based extender and seminal plasma removal on sperm viability of cooled donkey semen Texte intégral
2021
Carolina Natalia Alonso | Catalina Castañeira | Ana Flores Bragulat | Luis Losinno
Developing effective cooled semen protocols is essential to increase pregnancy rates and reproductive efficiency in donkeys. This study aimed to evaluate the effect on sperm kinetic parameters and membrane integrity in cooled donkey semen diluted with defined milk proteins extender with 1% or 2% of egg yolk and the removal of seminal plasma. Twenty-four ejaculates from six jackasses were collected. Each ejaculate was divided into four aliquots that were diluted in extender with 1% (EY1) or 2% (EY2) egg yolk. One sample from each group was centrifuged, seminal plasma was removed (CEY1, CEY2 groups, respectively), and the samples were then refrigerated at 5 °C for 24 h. Fresh and cooled semen samples were assessed for sperm motility, morphology, and plasma membrane integrity. Total motility, progressive motility, sperm kinetic parameters, or live sperm cells were not statistically different when semen was cooled with an extender supplemented with 1% or 2% of egg yolk. Seminal plasma removal does not affect total motility or sperm kinetic parameters. However, progressive motility decreased (P<0.05) when semen was extended with 2% of egg yolk and seminal plasma was removed. Membrane integrity was affected (P<0.05) in centrifuged samples. In conclusion, the obtained results suggest that there is no difference in sperm kinetics and membrane integrity when 1% or 2% of egg yolk was added to the Equiplus(R) extender. Also, the removal of seminal plasma by centrifugation did not have any beneficial effect on cooled donkey semen. Further studies are needed to relate these results with in vivo fertility tests with cooled donkey semen.

The objective of this study was to reach a diagnosis of the living conditions of abandoned donkeys kept in a restricted farm area through the assessment of their welfare level utilizing the AWIN protocol as a methodological tool. These animals were supposed to be sent to slaughter, but after the activity was temporarily banned, they were abandoned by traders. The protocol of welfare assessment was associated with general environmental and sanitary conditions. Information regarding the mortality rates was also gathered. According to the welfare assessment results, the living conditions of these animals were acceptable in some areas, despite the insufficient shade and shelter, a 3-month food restriction period, and a mortality rate of over 70%. These results demonstrate that welfare assessment protocols must be adapted to crises and databases for welfare indicators in diverse conditions must be created.

Buffaloes are one of the important farm animals in the south of Iraq and play an essential economical role mainly acting as dairy, meat, and draft animals. This study intended to diagnose buffalo mycotic eye infections in Thi-Qar province/Iraq. Some 250 buffaloes in the herd of 3,700 animals suffered from eye infections from December 2017 to November 2018. Eye swabs were collected from each infected eye of the affected buffaloes of both sexes before treatment. The animals were in different age groups. All samples were transferred to the laboratory in transfer media, and cultured on Sabouraud dextrose (SDA) agar with and without 0.05 g/mL and 0.4 g/mL chloramphenicol and cycloheximide, respectively. Later, the agars were incubated at 25o C and 37o C. The total percentage of eye infection was (6.75%), constituting (49.2%) mycotic infections. The predominant clinical manifestations that appeared on the infected buffaloes were eye inflammation represented by congestion, lacrimation, the opacity of cornea and edema, and reduced productivity of the infected animals. Different fungal isolates were identified from the samples including Aspergillus fumigates, Aspergillus flavus, Aspergillus niger, Penicillium spp., Alternaria spp., Fusarium spp., Candida spp., Cladosporium spp., Rhodotorula spp., Mucor spp. and Rhizopus spp. Calves buffaloes below one-year-old were more prone to mycotic infection than one-year-old or more. Additionally, male buffaloes were more susceptible to infection than females. In conclusion, this study isolated various types of fungus from the inflamed eyes of buffaloes. Fungal eye infection and the potential risk factors for fungal keratitis in buffaloes were also investigated. The study also approved the rapid diagnosis of fungi by direct microscopic detection and culture. The author recommends future studies including large numbers of the buffalo herd in Iraq to determine the epidemiology of this condition in the country.

Sporotrichosis is a dermatozoonosis, caused by dimorphic pathogenic fungi of the genus Sporothrix. Although Sporothrix brasiliensis is the most frequent and pathogenic species identified from the Brazilian sporotrichosis hyperendemic, to the best of our knowledge this is the first report of its molecular diagnosis from a cat with ocular lesions. A 3-month old female, domestic feline presented an ocular manifestation with granuloma in the lower-left palpebral conjunctiva, in addition to mucocutaneous lesions in varied locations throughout the body. Samples were collected for subsequent cytopathology, fungal culture, serology, and molecular genotyping. Itraconazole was prescribed for the treatment of sporotrichosis and the animal was considered clinically cured at the end of 5 months of treatment and discharged. S. brasiliensis cat interactions can manifest with a multitude of clinical forms that resemble either infectious or noninfectious diseases. Both the need for meticulous cat physical evaluation by a veterinarian followed by accurate laboratory diagnosis are key Public Health measures in the Brazilian sporotrichosis hyperendemic area.

Afficher plus [+] Moins [-]Proximal interphalangeal joint arthrodesis in horses: concepts, indications, and techniques Texte intégral
2021
Anderson Fernando Souza | André Luis do Valle Zoppa
Surgical arthrodesis is effective for treating proximal interphalangeal joint (PIJ) injuries in horses. Despite several techniques described so far, the use of a 3-hole, 4.5mm-locking compression plate, associated with two 5.5-mm transarticular cortex screws, is currently considered the “gold standard.” This review describes the anatomy of the pastern, as well as causes, indications, and possibilities for arthrodesis in the equine PIJ. A description of the current surgical technique for joint fixation is also presented.

This study aimed to verify if the process of artificial insemination (AI) characterized here as animal immobilization, the passage of the semen applicator through the cervix, and deposition of the semen in the uterus, affected cows’ welfare. For this, 18 beef calved cows were selected and divided into two groups: inseminated cows (AIG, n = 9), and not inseminated cows, the control group (CG, n = 9). Body condition score, uterus, and ovary evaluation were performed. Later, both groups were submitted into an estrus synchronization protocol and only the AIG group was inseminated. Blood components of urea, creatinine, AST, GGT, CK, glucose, triglycerides, cholesterol, HDL, LDL, VLDL, NEFA, BHB, cortisol, estradiol, progesterone, albumin, and total protein were measured 30 h before AI, and 4, 24, 48 and 168 h after AI. Statistical differences were considered when P <0.05. No differences between AIG and CG were observed. On the other hand, when the moment of insemination was evaluated, differences were observed for urea, creatinine, AST, GGT, CK, glucose, triglycerides, NEFA, BHB, albumin, and total protein. There was an oscillation of metabolic profiles depending on the time and procedures to which animals were exposed, even though it could be inferred that the AI process was incapable of altering those metabolic components on animals that were inseminated. Still, we can affirm that artificial insemination cannot be categorized as a negative reproduction tool on animal welfare. However, the containment and management procedures for AI may alter the metabolic profile of cows, especially the increase of CK.

This study aimed to compare the psychological profile of pet owners with the ones who didn’t own any pets. The research method was a casual-comparative study. Pet owners and people without pets were included in this research which was done in Iran in February 2017. One hundred and sixty people were selected in this sample in a nonrandom available sampling method and matched in terms of demographic characteristics. Eighty people, pet owners, were referred to the veterinary clinics and 80 didn’t own any pets. They were assessed by a psychological signs inventory. The result of ANOVA indicated that pet owners and those without any pets were indifferent in the characteristics of anxiety, obsessive-compulsive disorder, hostility, paranoid, interpersonal sensitivity, and psychosis, while those without any pets, statistically had a higher average in somatization and depression than the pet owners and it could be justified by corrective emotional experience, displacement, and sublimation in the pet owner. This statistic can be based on the fact that pet owners use these animals as an object for thrilling topics which is a factor to decrease their psychological stress and increase their physical health.
