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.

Cultivating catfish is one of the businesses that are of interest in Indonesia. The success of cultivation begins to be determined by the provision of seeds. Healthy seeds lead to a high survival rate, and unhealthy seeds due to disease will cause a high mortality rate, causing losses in the cultivation business. Bacterial infectious diseases Edwardsiella tarda can cause a low survival rate of catfish seeds, and even the death rate can reach 100%. This study aimed to evaluate and determine the best dosage of asam sunti in feed to control the pathogenic bacteria E. tarda infection in catfish. Asam sunti was given through feed with different treatment doses, with concentrate 0% (K), 0.5% (P1), 1% (P2), 2% (P3), and 4% (P4) for 14 days after being infected with pathogenic bacteria. The effect of giving asam sunti was measured by observing the survival of fish. The results showed that the administration of asam sunti could control the bacterial diseases of E. tarda bacteria sequentially control (K) is 0%, (P1) is 16.67%, (P2) 40%, (P3) 66.67%, and (P4) 90%. From these results, it can be concluded that the 4% asam sunti dose is the best dose for the survival of catfish seeds, with the survival rate for pathogenic bacteria E. tarda at 90%.

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.

De Roest, Kees | Molenaar, R. | Malchow, J. | Schrader, Lars | Bučková, Katarina | Niczyporuk, Jowita | Kozdrun, Wojciech | Tomczyk, Grzegorz | Thomas, Johan | Papasolomontos, Sotiris | Kefalas, George | Simitopoulou, Maro | Angastiniotis, Kyriacos
Many pig and broiler farmers struggle to reduce the use of antimicrobials on their farms. The improvement of the level of biosecurity certainly is one of the most effective ways to prevent pathogens entering the farm. Research is focused however also on other strategies, which may reduce the reliance on antimicrobials: increase animals’ resilience, early detection of diseases and targeted use of antimicrobials. These three strategies may exert a long term effect on the necessity tofight animal diseases. Several innovations are being tested that belong to these strategies, but most of these techniques have not yet been applied at farm scale In this paper a first analysis has been carried out to estimate the costs and benefits of innovations to improve resilience, to early detect diseases and to implement a targeted use of antimicrobials. As most of the innovations have been tested in experimental settings, the results of the economic analysis still have be treated with care. It provides however a first assessment of the economic convenience of the innovations and a list of key performance indicators that need to be taken into account in the analysis. For this analysis the partial budgeting approach has been used. Where broilers are concerned the analysis has been centred on on-farm hatching, elevated platforms, use of probiotics, automatic weighing systems and targeted use of non-antimicrobial feed and/or water additives. For pigs the analysis has been focused on innovative enrichment material to improve pig welfare and video-surveillance systems to early detect diseases.

Andrezza Cavalcanti de Andrade | Érica Pereira da Silva | Joana D'Arc dos Santos | Karina Pessoa Oliveira | Karla Patrícia Chaves da Silva | Márcia Kikuyo Notomi
Fourteen female dogs diagnosed with pyometra were studied at three separate times: at diagnosis (T0) and 24 h (T1) and 10-15 days (T2) after ovariohysterectomy (OH). The means of the markers, symmetric dimethylarginine (SDMA) (17.71 to 26.54 μg/dL) and the urinary gamma-glutamyl transferase to creatinine ratio (uGGT/uCr) (1.06 to 2.62 U/mg), varied, showing an increase with time. Further, the elevation of gamma-glutamyl transferase (uGGT) (56.61 to 128.12 U/L) and the urinary protein to creatinine ratio (RPC) (0.26 to 1.24) was evident at T0 and T1. A reduction in the means of RPC, uGGT, and uGGT/uCr was observed 10-15 days after OH. Despite the elevation of these markers, the concentration of creatinine (1.11 to 1.40 mg/dL), urea (40.07 to 67.16 mg/dL), and urinary specific gravity (1.027 to 1.028) only presented slight variation. In canine pyometra, complications secondary to acute renal injury may be present that may be mild and transient in most treated animals. As elevation in SDMA and RPC preceded changes in creatinine levels for the evaluation of glomerular filtration, tubular markers could assist in the early identification of renal damage in canine pyometra.
Afficher plus [+] Moins [-]Comparative digital study of two cranial rotation methods of the proximal fragment on the center of rotation of angulation-based leveling osteotomy planning with different tibial distal anatomical axes
2023
Barbara Georgina Cosgalla Navarro | Eduardo Alberto Tudury | Gabriel Ignacio Ramirez Flores
The center of rotation of angulation (CORA)-based leveling osteotomy (CBLO) technique was developed for cranial cruciate ligament (CrCL) rupture treatment, aiming to modify the mechanical-anatomical angle (AMA), which is described as a predictive risk factor for the disease and is recommended to be taken into consideration when one is choosing a surgical procedure for tibial plateau slope alteration. Identifying a tibial distal anatomical axis (DAA) is essential in CBLO surgical planning and measuring AMA amplitude. The aim of this study was: to evaluate two methods of cranial rotation of the proximal fragment using four different tibial distal anatomical axes for digital planning on the CBLO technique, comparing its effectiveness in achieving the desired tibial plateau angle (TPAd) and closing the AMA angle. Tibial measurements were made with the vPOP pro software using 30 mediolateral radiographs of canine stifles. The DAA described by four authors was used based on the amount of Rotation completed (Rc) for each. The rotation methods evaluated were: 1) commercial CBLO table (RT) and 2) overlapping the tip of the intercondylar eminence with the corresponding DAA line (RE). The TPAd to be obtained was fixed at 10°, and the final AMA to be achieved at 0°. The mean values and standard deviations of the final TPA and final AMA with the rotation method were TPA(RT)f(%TPAd), TPA(RE)f(%TPAd), AMA(RT)f(%AMAzero), AMA(RE)f(%AMAzero). The results of each author were Hulse 10.0 ± 0.3(46.6%), 9.9 ± 0.1(60%), 0.3 ± 0.3(33.3%), 0.3 ± 0.3(13.3%), Osmond 10.1 ± 0.2(75%), 10,1 ± 0.2(83.3%), 0.4 ± 0.4(33.3%), 0.4 ± 0.3(8,3%), Miles 10.0 ± 0.1(66.6%), 10.0 ± 0.1(75%), 0.2 ± 0.1(16.6%), 0.2 ± 0.1(8.3%), Tudury 9.6 ± 0.6(31.2%), 9.5 ± 0.2(31.2%), 1.0 ± 0.7(18.7%), 1.0 ± 0.6(12.5%), respectively. The initially described RT obtained a higher percentage of AMA at zero degrees. Therefore, the RE method is discarded for use as an alternative to CBLO planning.

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.

Fernanda de Carlo Deusdado | Carla Aparecida Batista Lorigados | Marianna Pantano | Ayne Murata Hayashi | Fabio Calderon
Gallbladder mucocele is characterized by hyperplasia of the gallbladder epithelium, increased mucus production, accumulation, and densification of the bile content, which can lead to biliary obstruction, necrosis, and rupture of the gallbladder wall. Its finding may be accidental or related to symptoms. A retrospective study (2016-2019) was carried out based on abdominal ultrasound examinations in dogs, correlating aspects of the gallbladder and biliary system in the mucocele with existing comorbidities. Thirty dogs diagnosed with biliary mucocele were evaluated, of which 46.66% had the disease at an early stage, and 53.33% showed a more advanced stage. Of these, 66.66% were related to endocrinopathies and hyperadrenocorticism. Signs of extrahepatic bile duct obstruction and biliary peritonitis were observed in two animals. Due to their potential risk of complications, follow-up ultrasound assessments are indicated in cases that opt for clinical treatment, not excluding the need for surgical intervention.

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.

In Brazil, lamb producers face challenges raising their animals because of high anthelmintic resistance and loss of productivity due to parasites. It is well known that parasitic infections can reduce the performance of sheep. However, until the publication of this work, no research was found that quantified the effects that anemia reflected by FAMACHA© scores can exert on other zootechnical indicators in a lamb production system. The objective of this study was to use the FAMACHA© scores to quantify the impacts of anemia in ewes at breeding and lambing on the productive and reproductive performance of a meat sheep flock. The variables evaluated were i) FAMACHA© score of ewes at breeding and lambing, ii) body condition score of ewes at breeding and at lambing, iii) average daily gain of lambs until weaning, iv) ewe’s age, v) birth weights per individual lamb and litter, vi) weaning weight, vii) ewe’s weight, viii) litter size and ix) pre-weaning survival. The treatments evaluated corresponded to the FAMACHA© score of the ewes during breeding and lambing. Quantitative responses were submitted to analyses of variance and compared by Duncan’s test. In contrast, qualitative or discrete responses were evaluated by the Kruskal & Wallis test and compared to Dunn’s test. The Wilcoxon test was performed to compare the FAMACHA© scores of ewes at breeding and lambing. All statistical analyzes were performed using the R-Studio software version 4.2.0 at a 5% significance level. The FAMACHA© score of breeding ewes was related to the body condition score at breeding, ewe weight, pre-weaning survival, ewe age, litter size, and birth weight. Furthermore, the FAMACHA© score of ewes at lambing was related to the body condition score at lambing, ewe weight, pre-weaning survival, birth weight per lamb and litter, pre-weaning average daily gain, weaning weight, and age of the ewe. There was no significant difference between the test times of the FAMACHA© scores of the ewes, indicating that an ewe will present a similar score at both stages. It was concluded that ewes with FAMACHA© scores of 4 and 5 and their offspring showed the worst productive and reproductive performances. Conversely, the ewes with FAMACHA© 1 obtained the opposite result, demonstrating better technical performance.
