This study aimed to assess the effects of thermogenic oils (safflower and coconut oils) as a replacement for ractopamine in heavy pig diets. A total of 24 mix-breed barrows with an average weight of 98.70 ± 1.63 kg were distributed in a randomized block design with four treatments and six replicates. Treatments were as follows: basal diet, modified basal diet + 10 ppm ractopamine, basal diet + safflower oil, and basal diet + coconut oil. Animal performance, organ weights, meat quality, carcass traits, and economic viability were determined. Data were analyzed using Duncan’s test at the 5% significance level. The safflower oil diet resulted in the highest carcass meat and ham weights, whereas the coconut oil diet provided the highest loin eye area and the lowest fat area, resulting in the highest meat/fat ratio. Analysis of economic viability indicators revealed that vegetable oil treatments differed significantly from other treatments in feed cost, feed cost per kilogram of live weight, economic viability index, and cost index, given that oil inclusion increased the price of diets. Supplementation of heavy pig diets with thermogenic oils is a viable alternative to enhance lean meat production, but its use depends on market availability and product price.

Chagas disease is caused by Trypanosoma cruzi, which has several forms of transmission. Among them, the vector route requires the constant action of the Health Surveillance in the control of triatomines. Our objective is to describe the diversity of triatomines and the rate of natural infection by T. cruzi in these insects, as well as to analyse entomological indicators, through secondary data generated by the Health Surveillance of the municipality of Barra, in the period from 2009 to 2019. The secondary data were subjected to descriptive analysis and the entomological indicators calculated. Williams’ G test and Fisher’s exact test were used to analyse the categorical data. A total of 10,913 triatomines of the genera Rhodnius sp., Panstrongylus sp., Eratyrus sp. and Triatoma sp. were captured, represented by 12 species. Triatoma sordida was the most prevalent 98.66% (10,767/10,913), reflected in the overall infestation index 7.61% (2,555/33,544) and triatomine density 0.24 (8,247/33,544). While the overall infection rate was 0.81% (41/5,048) and remained low during all years. There was significant association for T. sordida in relation to “T. cruzi infection index” and “Developmental stage” and “Capture site”. It is concluded that the municipality of Barra has a high occurrence of triatomines of various species, with T. sordida being the most prevalent species and responsible for the rates of infestation and infection by T. cruzi. The presence of these insects in households is a risk for the domestic cycle of the parasite, and thus can transmit T. cruzi to various domestic animals, including humans.

The aimed of this study was to evaluate the mineral composition in commercial cuts of tambaqui (Colossoma macropomum) and pirarucu (Arapaima gigas). Were compared to the minimum values of daily consumption of minerals recommended by the World Health Organization (WHO). The experimental design was completely randomized, with processing performed in triplicate. Data were submitted to ANOVA. If ANOVA appeared statistically significant (α=0.05), the means were compared by Tukey’s Test. There was a difference (p<0.05) between commercial cuts of the tambaqui for different minerals. Tambaqui ribs and band presented the highest values of total iron 1.08 ± 0.12 mg/100g compared to other commercial cuts. The mineral elements Na+, K+, Ca2+ and Mg2+ expressed the highest values for the tambaqui steak, 301.00 ± 80.58, 457.00 ± 129.33, 36.00 ± 4.36 and 46.90 ± 4.68 mg/100g, respectively. There was a difference (p<0.05) between commercial cuts of the pirarucu for different minerals. The mineral elements Total Iron, Na+, K+ and Ca2+ expressed the highest values for pirarucu loin, 0.80 ± 0.07, 406.00 ± 117.50, 529.30 ± 130.58 and 32.00 ± 5.12 mg/100g, respectively. However, Mg2+ expressed a higher value for pirarucu tail fillet 37.10 ± 4.99 mg/100g. The tambaqui steak and pirarucu loin were the cuts that best met the minimum needs for mineral supply.

The aim of this study was to evaluate the effect of veterinary dental gel containing Aloe vera and green tea, with and without a water additive in preventing calculus formation in dogs after all animals were initially submitted to periodontal treatment. The preventive treatment was performed on 72 dogs, which 24 received treatment with the veterinary dental gel (G1), 24 received treatment with the gel associated with a water additive (G2), and 24 dogs did not receive any treatment (G3). The animals also were subdivided into three groups according to their diet. The gel was applied directly to the dogs’ teeth and 500 ml of the additive was added to the water, three times a week. The animals’ teeth were photographed every 30 days to observe the time of new deposition of dental calculus. The images were analyzed by MATLAB. The dogs in G1 showed average of new accumulation of dental calculus of 254.8 days, those in G2 also showed an average return of 258.6 days, and G3 showed an average return of 156.7 days. There was a statistical difference between G1 - G3 (p-value = 0,000007885) and G2 - G3 (p-value = 0,00004568). There was no statistical difference between the different food groups. We concluded that the gel used in this study, associated or not with the water additive, was effective in helping to maintain the dental health of the animals for a prolonged period after the surgical procedure to prevent the calculus return.

Urinary tract infections are commonly diagnosed in dogs, accounting for 2 to 3% of cases in the clinical routine, as cystitis being the most reported condition. Dogs of all ages and breeds can be affected, and early diagnosis is an important tool for therapeutic success. Urine culture and antibiogram are gold-standard tests for the diagnosis of bacterial cystitis, allowing correct therapy and better recovery of the patient, since currently there is great resistance to antimicrobials used in the veterinary clinics. Thus, the aim of this study was to determine the main etiological agents isolated in dog urine cultures, as well as the resistance and sensitivity profile of the isolated agents in relation to antibiotics, in order to assist the clinician ́s choice of the most appropriate antimicrobial, aiming at the patient’s therapeutic success. For this study, a retrospective study was performed of 49 samples of urine cultures of male and female dogs, collected between 2012 and 2021, which were positive for bacterial growth. From this analysis, it was observed that Escherichia coli, Enterococcus spp. and Staphylococcus spp. were the most isolated agents, presenting higher antimicrobial resistance to cephalexin, sulfadiazine plus trimethoprim, ampicillin, enrofloxacin and ciprofloxacin, respectively.

A 20-month-old miniature mixed-breed heifer weighing 200 kg was presented with a history of dysphagia, sialorrhea and dyspnea after being fed with food residues. At home it was treated with intravenous hydration, antibiotic combination, diuretics and AINEs. Additionally, one failed passage of oro-ruminal tube and several ruminal trocarizations were performed. At clinical examination the animal showed signs compatible with digestive obstruction, severe dyspnea and shock. Complete blood count showed leukocytosis with neutrophilia, left shift and lymphocytosis. Serum chemistry tests showed hyperlactatemia, hypokalemia, hypocalcemia, hyperglycemia and azotemia. Acid-base analysis indicated severe metabolic acidosis and respiratory alkalosis. Esophagoscopy was performed, during which the patient went into shock and died. In necropsy a complete middle third esophageal obstruction with rupture by a carrot was identified.

Neurological disorders are frequent in small animal veterinary clinics and studies giving regional justification for such disorders are essential so that veterinarians can be better prepared. The objective of this retrospective study was to describe the clinical and epidemiological aspects of dogs with neurological disorders treated at the Veterinary Hospital of Federal Rural University of Rio de Janeiro, between August 2017 and April 2018. The study describes the location of the lesions and their etiology according to the acronym VITAMIN-D, as well as the distribution of cases according to sex, breed and age. One hundred and twenty-two (122) dogs were included, of which 58% (n=71) were males and 42% (n=51) females. The age distribution ranged from two months to 18 years old; 16% were less than two years old, 50% between two and seven years old and 34% were more than seven years old. The most affected breeds were Mixed Breed dogs (43%), Poodles (9%) and Dachshunds (7%). The diagnoses were confirmed in 54 animals (44%) and in 68 (56%) remained presumptive. The most common location was the spinal cord (61%), where the T3-L3 region was the most affected (35%), followed by multifocal (20%) and forebrain (10%). The most frequent categories were degenerative (24%), inflammatory/infectious (23%) and traumatic (20%) diseases. Intervertebral disc disease was the most observed, corresponding to 21.3% of all cases. The results showed that the neurological diseases in this Veterinary Hospital were more prevalent in young male adults with spinal cord diseases of degenerative nature.

Hyperadrenocorticism is a relatively common endocrinopathy in middle-aged and older dogs, which has become increasingly frequent in the clinical routine. The diagnosis is made by information obtained by history, physical exam findings and results of screening and specific endocrine tests. In addition to laboratory tests, imaging diagnosis, such as ultrasound, can aid on evaluation of possible changes in these cases; also, they may reveal the possible involvement of other organs and systems. The aim of this study was to present the main ultrasonographic changes observed in 18 dogs with hyperadrenocorticism, diagnosed from 2013 to 2020 by the low-dose dexamethasone suppression test, among which hepatomegaly, splenomegaly, gallbladder sludge, renal changes, cystitis and changes in adrenal size, such as bilateral and/or unilateral adrenomegaly, can be cited. Ultrasound examination, therefore, is an examination that can help the clinician in confirming the diagnosis of hyperadrenocorticism, in addition to allowing differentiation between pituitary-dependent hyperadrenocorticism (PDH) and adrenal tumors, and the evaluation of possible secondary changes to the disease.

Ultrasound examination, therefore, is an examination that can help the clinician in confirming the diagnosis of hyperadrenocorticism, in addition to allowing differentiation between pituitary-dependent hyperadrenocorticism (PDH) and adrenal tumors, and the evaluation of possible secondary changes to the disease.","PeriodicalId":38626,"journal":{"name":"Acta Veterinaria Brasilica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44575990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Agoutis (Dasyprocta prymnolopha, WAGLER 1831) have been studied in captivity as a potential source of meat for rural populations in Brazil, as a way of providing low-cost protein and easing hunting pressures in local communities. However, little is known about their physiological blood markers, which are crucial for animal husbandry and effective welfare management. This study provides hemogasometric and ionic venous parameters for female agoutis raised in captivity in the drylands of Brazil. Venous blood samples were collected from six females and analyzed for dissolved gases and ions in the blood. Hemogasometric parameters, especially base excess and anion gap were generally heterogenous, while ions varied little among individuals. Moreover, we observed high chlorine values and negative base excess values, which suggest that some animals might be implementing compensatory mechanisms for ion imbalances. We provide a preliminary note on agouti venous gases and ions, while reiterating the importance of the clinical context and in-house parameter definition to maximize accuracy.

Consumers demand for food safety affects dairy industry, restraining the sector to adapt to milk quality parameters established by legislation, such as somatic cell count (SCC) and standard plate count (SPC). Good agricultural practices have positive impact over these parameters, especially Forestripping Milk (FSM), which consists of observing the first milk streams collected in a dark-bottomed mug for identification of clinical mastitis. These first milk streams have high somatic cells count and bacteria. Therefore, the aim of this study was to evaluate the characteristics of milk from FSM, such as SCC and SPC values, and its impacts on milk quality of the cooling tank through simulating contamination. Fourteen dairy farms and one experimental farm were evaluated for SCC and SPC parameters of FSM. It was observed that there was no statistically significant difference for SCC and SPC between milk samples from the cooling tank and cooling tank simulating the inclusion of milk from FSM. Statistically significant difference for somatic cell score (SCS) and SPC was observed when tanks were classified by SCC. In addition, difference in SCS was observed between morning and afternoon milking. The collection of first milk streams can contribute to decrease in SCC and SPC of milk in the cooling tank. FSM must be practiced by all dairy farmers as milking management, to assist in clinical mastitis diagnosis and improve milk quality.
