National dairy production is characterized by significant heterogeneity in production techniques and herd and farmer profiles. Our objective was to characterize 18 dairy farms under family farming in Senador Guiomard, Acre State, from January to December 2019. Data were gathered through 255 question semi-structured forms applied to farmers in monthly visits. The data were then stored in Excel® spreadsheets and subjected to descriptive statistics. A joint analysis showed the following characteristics: farmers with low schooling level (89%); farmers of advanced age (61%); nonadoption of good dairy practices (100%); inadequate milk transport (72%); adequate brucellosis vaccination (100%); non specialized herds (40%); pasture production system (100%); low productivity per area (873 L/ha/year) and per cow (4.0 liters/cow/day); low number of lactating cows (53%); and gross milk income (29,466.65 R$/year) representing 69% of the total gross income. The region studied has positive factors such as market guarantees, proximity to large market centers, reasonable land prices, suitable climate, ease of credit, rural education, and technical assistance. Overall, the farms are managed under a traditional production system, with low use of technology and unsatisfactory zootechnical indexes. However, the region has favorable conditions for dairy farming development.

One of the fishery products that decomposes very rapidly is shrimp. Utilizing natural preservatives, such as Averrhoa bilimbi L. juice, is one method for maintaining the quality of food ingredients. This study aims to determine the effect of adding A. bilimbi L. juice with different concentrations and soaking times on vannamei shrimp decay. In this study, an experimental laboratory was used to examine decay using the Postma and H2S tests. As much as 500 g of vannamei shrimp were divided into four treatment groups and two repetitions, with 5 g of each sample soaked in A. bilimbi L. juice with concentrations of 0%, 2.5%, 5%, 7.5%, and 10% for 0, 3, 6, and 9 hours. Early decay was observed at 0 and 3 hours after soaking vannamei shrimp in solutions with concentrations of 0%, 2.5%, 5%, 7.5%, and 10%. At concentrations of 5%, 7.5%, and 10%, there was no initial decay after soaking vannamei shrimp for six hours at a concentration of 0% and 2.5%. During 9 hours of soaking at concentrations of 0%, 2.5%, and 5%, initial decay occurred, whereas there was no initial decay at concentrations of 7.5% and 10%. The conclusion of this research is A. bilimbi L. juice with concentrations of 7.5% and 10% for 6 and 9 hours inhibits the decomposition of vannamei shrimp.

The impact of free radicals on testicular Leydig cells can result in the disruption of male reproductive health. The present study aimed to evaluate the effects of a high-fat diet on Leydig cells and the potential of kepok banana peel extract as a medication to mitigate these effects. In total of 20 adult male Wistar rats were assigned to five groups and treated with standard feed (P1), high-fat feed (P2), high-fat feed with simvastatin (P3), and high-fat feed with banana peel extract at doses of 100 and 200 mg/kg BW (P4 and P5). After 60 days of treatment, the number of Leydig cells was determined using HE staining methods. Data were analyzed using an One Way ANOVA test. The results showed that the administration of 100 mg/kg BW of kepok banana peel extract (P4) was able to maintain the number of Leydig cells and counteract the negative effects of a high-fat diet. These findings suggest that kepok banana peel extract may have the potential as a herbal medicine for supporting male reproductive health.

Birds are organisms that can be found in a variety of habitats. One of the bird habitats is paddy fields. Birds found in paddy fields generally carry out activities such as foraging, breeding, and competing. This study aims to determine the diversity of birds in paddy field habitats during the paddy ripening phase (Oryza sativa L.). The study was conducted from April to June 2022. The location of the study was Jurong Peujera Village, Ingin Jaya District, Aceh Besar Regency. This study used the Point Count method with a radius of 50 m and a distance between points of 150 m. Observations were made at 9 observation points with 4 repetitions, in which the duration of observations was 10 minutes at each observation point. The observation was conducted in the morning and evening at 06.30-10.00 AM and 03.30-05.00 PM. The results obtained were 2586 bird individuals consisting of 14 species from 11 families. The species with the highest number of individuals are Lonchura punctulata with 1535 individuals and Bubulcus ibis with 637 individuals. The highest percentage of families by species is Ardeidae (22%), and Estrildidae (15%). The Shannon-Wiener bird species diversity index in the paddy field area during paddy ripening phase was obtained H'=1.24 which indicates the level of diversity of the bird species is moderate. Meanwhile, based on the dominance index, Simpson shows a value of C=0.42 which indicates a low bird dominance level. The low level of bird dominance is due to the moderate diversity of species in the paddy field area.

Mastitis is one  of the causes  of diseases that can reduce livestock production.  Mastitis can be caused by various types of bacteria that cause a decrease in livestock production that is difficult to cure with antibiotics has been reported resistance. This study aims to determine gram-negative bacteria that can be the cause of mastitis in cows. The study used samples taken from folk farms by means of livestock udder swabs. Bacterial isolation is carried out by  planting in Mannitol Salt Agar (MSA) media  and identifying by Gram staining  and  biochemical tests (maltose and lactose). The data analysis used is descriptive analysis, namely the types of bacteria as the causative agents of mastitis.  The results of the study obtained bacteria that cause mastitis of  gram-negative species Klebsiella  sp and Enterobacter sp yang classified as Gram-negative  bacteria. It can be concluded that in cows indicated mastitis there are Gram-negative bacteria, these are morphologically identified, namely Klebsiella  sp and Enterobacter sp.

Cytauxzoon felis is a hemoparasite capable of infecting domestic and wild cats. Studies suggest that wild cats are the main reservoirs of the protozoan, and transmission occurs through the bite of an infected tick. Hemotropic mycoplasmas are Gram-negative bacteria responsible for severe hemolytic anemia. The feline immunodeficiency virus (FIV) is a retrovirus capable of generating immunosuppression in the host and persistent infection. The present work describes a case of co infection of Cytauxzoon felis, Mycoplasma haemofelis, and feline immunodeficiency virus (FIV) in a cat. A feline from the rural area was admitted to the Veterinary Hospital of Uberlândia - MG of the Federal University of Uberlândia. Fresh whole blood samples were collected for blood count, enzymatic analysis, DNA extraction, real-time PCR for the detection of Cytauxzoon felis and Mycoplasma haemofelis, and the Point of Care ELISA test for Feline Leukemia Virus (FeLV) antigens and antibodies to feline immunodeficiency virus (FIV). Piroplasms compatible with Cytauxzoon spp. were observed in the smear, and the tests performed were positive for Cytauxzoon felis, Mycoplasma haemofelis, and FIV.

Leptospirosis is a zoonotic disease in the tropical zone with a broad and endemic distribution. The condition is complex, where different host factors, serovar type, reservoirs, environment, and agricultural practices intervene. In cattle, the disease causes significant damage to the livestock sector, and the surrounding conditions can influence its dynamics. This study aimed to determine the seroprevalence of anti-Leptospira spp. antibodies and the risk factors in cattle in the tropical savannah from eastern Colombia. Blood was taken from the coccygeal veins of 1,000 animals. The MAT (Microagglutination) technique was used for the identification of the serogroup Autumnalis, Bataviae, Bratislava, Canicola, Copenhagen, Cynopteri, Grippotyphosa, Sejroe, Mini, Pomona, Shermani, Tarassovi, and Celledoni. Studies of risk factors were carried out according to the serovar through the calculation of X2 and OR. Seroprevalence of Leptospira spp. was 34.2% with 92.3% of herds. Pomona had the highest frequency of 7.9%, followed by Hardjo prajit with 7.0% and Grippotyphosa with 6.2%. Antibody agglutination with more than one serovar was seen in 102 (29.8%) samples. The serogroup with the highest correlations were Pomona and Hardjo prajit.

Both pregnancy and obesity can influence significant changes in the immune system. On this basis, the present study proposes to evaluate the humoral immune response of overweight pregnant mares in response to a commercial vaccine. Thirty pregnant Crioulo mares were separated according to body condition score (BCS) into overweight (BCS≥7/9) or lean-control (BCS= 5-6/9). In each group, the animals were subdivided into vaccinated and controls. The mares were vaccinated against EHV-1 in two doses spaced 21 days apart and had their blood collected monthly, for five months, for antibody evaluation. Both vaccinated groups had an increase in specific neutralizing antibodies after the vaccine. However, after the second dose, there was no increase in antibodies in any of the groups. Vaccinated overweight and lean-control mares did not differ at any time point. Therefore, this study demonstrated that obesity does not influence the humoral immune response in pregnant Crioulo mares.

Studies on the interactions between the intestinal microbiome and its host have strengthened in the last decade. However, publications on this topic in dogs still need to be made available, reinforcing the need for new studies and literary data for consultation. Given this, this review aims to describe the intestinal microbiome and its interactions with the canine host, which can contribute to both health and morbid conditions in these animals. The definition of microbiome encompasses the collective genome of all microorganisms that live in a defined habitat (intestine). It is known that the dog’s intestinal microbiota is varied, composed of bacteria, archaea, viruses, fungi, and protozoa. Under normal conditions, there is commensalism between some of these microorganisms and the host, which promotes critical physiological relationships and interactions that contribute to homeostasis and the consequent health of the animal. With this in mind, it is expected that the disturbances associated with the microbiome will result in imbalances in this commensal relationship and thus precipitate the development of diseases and aggravation of other diseases, thus characterizing intestinal dysbiosis.

The present study aimed at assessing the effects of combining 20 mg/kg S(+) ketamine with 25 μg/kg dexmedetomidine and 0.4 mg/kg butorphanol on the physiological parameters and anesthetic recovery time and score of eight captive scarlet macaw (Ara macao) specimens. These specimens were captured at the Marabá Zoobotanic Foundation (Fundação Zoobotânica de Marabá), Pará, using butterfly and mist nets, and subsequently subjected to the proposed protocol. The following physiological parameters were evaluated: heart rate (HR), respiratory rate (RR), saturation of peripheral oxygen (SpO2), body temperature (BT), and non-invasive blood pressure 5 min after drug administration (M0) and every 10 min thereafter (M1‒M5), with a total of 55 min of analysis of anesthetic effects. Glycemia was measured 5 min after drug administration and every 30 min thereafter. Anesthetic induction and recovery times were also determined. Among the parameters evaluated in this study, both HR and BT significantly decreased throughout the anesthetic period, with the lowest levels at 55 min after drug administration (M5). In contrast, RR did not significantly differ, and all animals remained stable, maintaining an RR close to a mean of 20 ± 8 cpm. Throughout the anesthetic period, SpO2 was 92 ± 5%, with no significant difference. The birds remained under spontaneous ventilation and without oxygen supplementation. Systolic, diastolic, and mean blood pressures remained stable, with no significant differences in any of these measurements. At M0 and M3, the glycemia decreased slightly, albeit with no significant difference justifying an adverse effect or even hypoglycemia. The anesthetic induction time, from M0 to decubitus, was 2.4 ± 0.7 min. The anesthetic recovery time, from M0 to effortless bipedal position and adequate phalangeal flexion, was 99.3 ± 32.4 min. The sedation was assessed as intense, and the anesthetic recovery was rated excellent in 62.5% and good in 37.5% of the animals.
