Poultry production in Colombia is one of the main activities given the high consumption of this protein, due to its easy access for the entire population. According to the indicators of the Ministry of Agriculture, the poultry sector registered in the 2020 a growth of 4.5% and according to FENAVI for 2020 the per capita consumption of chicken was 35.5 kg / year. The industry has been affected by the different diseases that affect birds, one of these is viral arthritis or tenosynovitis which is a serious economic and health problem for the industry. The objective of this research was to carry out a literature review of the current state of knowledge about the factors associated with the presentation of tenosynovitis in broilers. For this, a review was carried out in databases (ScienceDirect, Pubmed, Scopus, among others) to search for documents and articles related to the subject. A total of 359 articles were found, of which 12 were finally selected for the review. Given that viral arthritis or tenosynovitis is a disease caused by avian arboviruses (ARVs), the findings of the different studies associated with ARVs show that in recent years these pathogens have evolved through greater genetic diversity and their pathogenicity. Therefore, since the control of the disease associated with ARV infection is increasingly difficult, new prevention and control measures are required, since vaccination has proven not to be totally effective.

Homeopathy is one of the most widely used practices in alternative medicine, both in the care of human pa-tients and in veterinary medicine. Its origin dates back a little over 200 years and its popularity has been up and down ever since. Since its beginning and until modern times, the postulates of homeopathy have been the subject of debates in medicine and science. Concepts applied in homeopathy such as similia similibus curentur, vital force, dynamization, minimum or infinitesimal doses, and other peculiarities of the practice, are currently little recognized or even completely rejected. The weakness of homeopathy’s theoretical framework and the scant of serious evidence it has provided makes it difficult to consider it as a tool of modern scientific medicine. In this review of the available literature, the principles of homeopathy, the experimental evidence of its efficacy, and its suitability in current medicine are described in a critical and rigorous way, to determine whether it can be considered an acceptable medical and veterinary practice in the XXI century.

A study was carried out to evaluate in vivo the dermal and ophthalmic irritant potential of the Curcuvet product (antiseptic and healing solution for veterinary use obtained from the hydroalcoholic extract of C. longa). The acute dermal toxicity, primary dermal irritability and ophthalmic irritability tests were carried out in Sprague Dawley rats, F1 rabbits and New Zealand albino rabbits, respectively, as established by the Organization for Economic Cooperation and Development (OECD No. 402, 404 and 405). The animals exposed to Curcuvet du-ring the dermal toxicity tests did not show clinical signs that evidenced toxic processes. In contrast, the ocular conjunctiva, iris and cornea were severely damaged from the first hour after application, reaching an irritability index of 110. It is concluded that the Curcuvet formulation administered in a single dose, classifies as non-der-mal irritant and as severe ophthalmic irritant.

The purpose of this study was to analyze the influence of COVID-19 on the export, production, and consump-tion of beef in Colombia in relation to the world. Information related to the export, production and consumption characteristics of beef was searched using exclusion criteria and keywords in web pages such as ScienceDirect and Google academic. FAO and DIAN databases from 2018 to 2020 for Colombia, Brazil, India, Australia, USA and China were consulted. Results showed an increase of 52% in beef exports in the last year in Colombia, while production and consumption per capita showed a negative trend. The above may indicate a positive artificial effect on the impact of the Colombian beef market. The studied traits trends showed the COVID-19 pandemic impact on the global beef market. In conclusion, regarding the assessment of Colombian beef exportation, it is essential to consider the international negotiation policies of the Colombian beef importing countries and each country’s response capacity to meet its consumer demand which directly affects imports. Finally, the pandemic affected Colombian beef exports because of its domestic presentation and evolution and its impact on the countries of Colombian meat imports.

Geo-helmintiasis are recognized due to their high morbidity and because they cause thousands of deaths annually, mainly of children in underdeveloped countries. There is a global proposal with a goal to be achieved, knowledge of the prevalence of geo-helminthiasis is essential. Even so, it is possible to assess the regions should receive greater attention in the search for treatment and control. The objective of this study is to evaluate the prevalence of infections due to geo helminthiasis in Brazil based on the analysis of the published literature. Methodology: For this, a systematic review of articles in PubMed, Scopus and Science Direct databases was made considering studies in which parasitological copro examinations were performed between 1/1/2010 and 8/17/2020. Studies representing the following data were included: number of participants, age group, parasi-tological method, geographic location. A total of 25 studies were identified with reports of prevalence in rural communities, indigenous school children, urban and peri urban areas. The studies were carried out in twelve Brazilian states in the South, South West and North West region. Results: 56% of the studies included individuals aged 0 to 93 years. The techniques base on spontaneous sedimentation were the most used. Ascaris lumbricoides was another species found (0,15 to 48,8%), followed by Trichuris trichiura (0,16 to 61,5%) and hookworns (0,08 to 22,8%). The state of Rio Grande do sul (RS), Minas Gerais (MG), Paraná (PR), Alagoas (AL) and Bahia (BA) had higher reports (>20%) of Ascaris lumbricoides and it also represented reports for T. trichiura (PR, AL and BA) and hookworms (MG, AL and BA). Conclusion: In Brazil, studies on the prevalence of soil transmitted helminth infections are scarce, mainly in regions of extreme poverty, the published works do not refer to the prevalence of municipalities and of certain communities, which doesn’t not always represent the reality of the local. More studies on the prevalence of infections due to soil transmitted helminth infections are necessary to know areas of greater risk where the measures for treatment and control should be more effective.

The genetic improvement programs in broilers are updated based on parameters of interest such as zootech-nical performance, yield and quality of the carcass, as well as economic viability. Therefore, the development of new genetic lines that respond positively to the productive challenges of the industry is one of the biggest challenges found today. The objective of this work was to evaluate the zootechnical performance and degree of feathering of the birds during their productive cycle. There were used 2400 male and female broilers, distributed in randomized blocks in a 2 x 2 factorial system (Sex x Line), being two sexes and two genetic lines (line A x Line B) with 12 repetitions per treatment. The birds were distributed in 48 corrals of 2.25 x 1.50 with an initial occupation of 50 birds per corral (14.8 birds/m2), the feeding and lighting program was established by the company. Zootechnical performance parameters were evaluated weekly and the feathering degree on day 41. The data were analyzed by the statistical test of T student and U Mann Whitney’s in data that did not have normal distribution, using the IMB program SPSS 25. No significant differences were observed between the genetic lines evaluated for the variables of body weight, feed consumption, feed conversion, weight gain and efficiency at day 41 of age. With respect to the degree of feathering, the females of the B line presented a greater degree of feathering than the other treatments.

Introduction: Carnitine is key in the proper metabolism of lipids, so its deficiency can trigger metabolic and productive problems during peripartum, for this reason, the objective of this study is evaluated the parenteral application of various doses of L-carnitine to cows during the peripartum; Methodology: Each treatment consisted of six Holstein cows between second and sixth birth to Holstein cows of high production, grazing kikuyu grass (Cenchrus clandestinus [Hochst. ex Chiov.] Morrone) and supplemen-ted with a concentrate food 0, 5, 10 and 15 grams of L-carnitine in solution were applied via intramuscular every 5 days from day 270 of gestation to day 15 postpartum on dry matter intake (DMI), energy balance (EB), milk was estimated using the indicator technique. MY, MF and MP were measured on days 5, 10, 15 and 20 of lactation. On day 270 of gestation and on days 10 and 20 postpartum the EB of each cow was calculated. Results: The results of these measurements are analyzed in a time-divided plot design. Conclusions:The treatments do not affect DMI, MY, MP, MF and EB (p> 0.05), under the experimental conditions described in this work, parenteral L-carnitine has no effect on milk production, composition and EB

Introduction: Acquired myasthenia gravis (AGM) is an immune-mediated disease that presents a decrease in the number or functionality of acetylcholine receptors at the nicotinic level. This leads to less effective muscle contraction. The most common clinical manifestation is episodic weakness that increases with exercise and improves with rest. Other clinical signs are: regurgitation and voice changes. The purpose of this report is to describe a canine, female with dysuria without stranguria who was taken to the Hospital School of Veterinary Medicine of the University of Buenos Aires. Methods: blood and urine tests, urine cultures, spinal radiographs, abdominal ultrasound, electromyography (EMG) of the anal sphincter and repetitive stimulation were performed. Antibodies against acetylcholine receptors (ACRA) were measured. Results: blood tests, urinalysis, spinal radiographs and abdominal ultrasound were normal. Urine cultures were negative. Anal sphincter EMG was preserved. Repetitive stimulation EMG was compatible with MGA. The patient was ACRA positive and his response to treatment with pyridostigmine bromide (BRP) was favorable. Conclusions: include MGA in canine patients with dysuria in the deferential diagnosis
