ABSTRACT: The study evaluated the effects of replacing corn with whole and ground sorghum on the zootechnical performance of turkeys fed from one to 28 days of age. A total of 3,960 male Nicholas turkeys were used, divided into six treatments: A) Whole sorghum (100%Sw); B) Ground corn (100%Cg); C) 75% Ground Corn + 25% Ground Sorghum (75%Cg/25%Sg); D) 50% Ground Corn + 50% Ground Sorghum (50%Cg/50%Sg); E) 25% Ground Corn + 75% Ground Sorghum (25%Cg/75%SG) and F) Ground Sorghum (100%Sg). At seven days, live weight was the same between treatments (164 g per bird). At 28 days, the percentage of breast, thigh-drumstick, and wings remained constant in the corn-based diet or partial and total replacements by ground or whole sorghum grain. The length of the small intestine was shorter in treatments B and C. The digestibility of the lipid fraction of the diet (DEE) was significantly higher in the diet with ground sorghum. The treatment based on ground sorghum grain showed the same result for ground corn in the dry matter (DM) and mineral matter (MM DM%) composition of the turkey carcass at 28 days. Ground sorghum influenced the lipid portion of the carcasses (EE DM%). Thus, it is concluded that whole sorghum grain presented the same results as ground sorghum and ground corn for zootechnical performance, carcass muscle mass, and viscera morphometry in turkeys at 28 days of age.

ABSTRACT: Intra-abdominal or intrascrotal testicular torsion in dogs occurs due to spermatic cord rotation. Dogs with testicular torsion commonly present severe pain and require surgical intervention. Torsion of intra-abdominal retained testicles in cryptorchid adult dogs is often associated with the presence of testicular neoplasia. Herein, we reported the case of a 5-year-old male poodle with uncommon intra-abdominal testicular torsion (ITT) of a non-neoplastic testicle. The dog was referred to the veterinary hospital with acute abdominal pain in the hypogastric region. An intra-abdominal gonad and alterations compatible with testicular torsion were visualized during ultrasound examination. Orchiectomy and histopathological analysis of the testes confirmed the diagnosis of ITT in the absence of neoplasia. The patient recovered uneventfully from the situation. This report showed that ITT can occur in adult dogs in the absence of testicular neoplasia and reinforce the message that it should be included as a differential diagnosis in cases of acute abdominal pain in cryptorchid dogs. Furthermore, the ultrasound examination in this case of pain in the hypogastric region was decisive for the diagnosis of ITT.

ABSTRACT: Promoting the agricultural sustainable development is one of the core objectives of agricultural comprehensive development (ACD), and the core of agricultural sustainable development lies in enhancing agro-ecological efficiency (AEE). Based on inter-provincial panel data from 2003-2017, the AEE was measured by a unexpected super-efficient SBM model. From the perspective of investment scale and investment structure, the impact of investment scale in ACD on AEE was examined using a panel econometric model, then characterizing the investment structure by the proportion of government funds in the investment of ACD, examining the non-linear relationship between investment structure of ACD and AEE seeking a reasonable proportion of government expenditure. Finally, a spatial econometric model was constructed to test the spatial spillover effect of the scale and structure of investment in ACD on AEE. Results showed that: (i) AEE of China is on the rise overall, but the efficiency level is still low and there is large scope for improvement. (ii) Due to the inefficient use of funds and the lag in the transformation of agricultural benefits, the scale of investment in ACD has a significant negative impact on AEE in the current period. (iii) The impact of investment structure of ACD on AEE presents a significant “inverted N” relationship, and the optimal proportion of government fund investment structure is 76.71%. The reasonable structure of investment in ACD at different food functional areas shows differences. (iv) After considering the spatial effect, the impact of ACD remains robust, but the spatial spillover effect prolongs the time lag of this impact of investment scale and starts to have a positive impact in the 2nd year after the investment. Guarantee the investment scale in ACD, reduce financial redundancy, establish a cooperation mechanism between ACD and agricultural ecological protection in neighboring areas, and increase the introduction of private capital can achieve sustainable development of agricultural economy.

ABSTRACT: The knowledge of water consumption and the efficiency of water use by crops is extremely important in the elaboration of agronomic and hydraulic projects of hydroponic systems. Thus, the present study determined the water consumption and water use efficiency of ‘Biquinho’ pepper cultivated in the hydroponic system using seven levels of electrical conductivity of the nutrient solution (ECsol) of 2.70, 3.64, 4.58, 5.28, 6.09, 6.90, and 7.77 dS m-1 and six replicates in randomized blocks. The hydroponic system used was the Nutrient Film Technique (NFT). The water consumption per plant was determined at an interval of ten days in the crop cycle (120 days after transplanting). The maximum mean daily water consumption was equal to 5.88 L plant-1 during the period 111-120 DAT, for ECsol of 4.58 dS m-1. The maximum water consumption for the crop cycle (120 DAT) was 275.66 L per plant for an estimated ECsol = 4.11 dS m-1. The highest water use efficiency (WUE), based on the total production of fruit fresh mass (ripe and unripe fruits) of ‘Biquinho’ pepper was 10.84 kg m-3 up to an estimated ECsol of 5.18 dS m-1, with an exponential reduction thereafter. The salinity of the nutrient solution, biomass production, and evapotranspiration are factors that influence the most water consumption of ‘Biquinho’ pepper.

ABSTRACT: Hemilaminectomy and intervertebral disc fenestration are commonly used to treat intervertebral disc extrusion (IVDE); however, they are associated with surgical complications. Sixty-four dogs were assessed during the intraoperative, immediate postoperative, and late postoperative periods to evaluate complications resulting from these surgical procedures. During this study, 15.62% (n=10) of the dogs presented with complications during at least one of the evaluations. Iatrogenic rhizotomy, access to the spinal canal contralateral to the lesion, and cardiorespiratory arrest were observed intraoperatively. Abdominal wall flaccidity, neurological worsening, hematoma, dehiscence, and superficial wound infections were observed during the immediate postoperative period. Adverse reactions to the surgical thread, scar adhesion, and superficial wound infection were the most frequent complications during the late postoperative period. Dogs that undergo hemilaminectomy and intervertebral disc fenestration because of IVDE may experience complications during the intraoperative, immediate postoperative, and late postoperative periods. However, these complications are often transitory and rarely cause death.

ABSTRACT: The aim of the present study was to characterize (phenotypically and genotypically) two strains of Brucella abortus identified as belonging to biovar 4 isolated from cattle in Brazil. The strains were isolated from cervical bursitis from cattle in the states of Pará and Rio Grande do Sul, respectively. In the phenotypic identification, the isolates were positive in CO2 requirement, produced H2S, were resistant to basic fuchsin (20 µg / mL) and sensitive to thionin (20 µg / mL and 40 µg / mL) and presented M surface antigen, but A surface antigen is absent. The isolates were positive in the PCR for the bcsp31 gene (genus-specific) and in the AMOS-enhanced PCR, both isolates showed a band profile consistent with B. abortus biovar 1, 2 or 4. Moreover, both isolates also showed restriction patterns identical to the reference strain when tested by the omp2b PCR-RFLP. In genotyping using Multiple Locus Variable Number of Tandem Repeat (VNTR) Analysis - MLVA (MLVA16), the isolates showed differences in several loci (Bruce42, Bruce19, Bruce04, Bruce16 and Bruce30); by Multiple Locus Sequence Typing (MLST), they also exhibited differences in sequence type (ST), strain 16/02 ST1 (2-1-1-2-1-3-1-1-1) and strain 128/11 ST (22-1-1 -8-9-3-1-1-1). The extensive typing of B. abortus strains isolated from cattle in Brazil using different approaches confirmed the occurrence of rare B. abortus biovar 4 in the country.

ABSTRACT: Although the JmjC domain-containing histone demethylases displayed a crucial role in maintaining the homeostasis of histone methylation, while the systematic identification and functional researches of JmjC domain-containing gene family have not been conducted in Mung bean (VrJMJgenes). According to the structural characteristics and phylogenetic relationship with their orthologs from Glycine max, Lotus japonicus, Medicagotruncatula, Arabidopsis thaliana, and Oryza sativa, a total of 18 VrJMJgenes were identified and divided into four clades (KDM3, KDM5. PKDM8, and PKDM9). Interspecies co-collinearity analysis showed the significant JmjC gene duplication events which have occurred during the Papilionoideae evolution. The exon/intron and domain organization of VrJMJgenes from the same clade (or subclade) were similar. All VrJMJ proteins contained a conserved JmjC domain, meanwhile other essential domains also have been found in some specific VrJMJ proteins which responsible for their functions. Numerous abiotic stress and light response related cis-elements associating with transcriptional regulation that were demonstrated in the promoter regions of VrJMJgenes(Pro VrJMJs ). Expression profiles of VrJMJgenes in different tissues showed that most genes displayed a tissue-specific expression in roots or leaves. The acronym RT-qPCR results showed that all VrJMJ genes displayed different degrees of abiotic stress (drought, salinity, and cold) and photoperiodic responses. Furthermore, VrJMJ3 and VrJMJ9 were significantly up-regulated after all three abiotic stress treatments, and VrJMJ13 exhibited a potential function in the photoperiodic regulation of Mung bean flowering. These results provided a clear understanding of VrJMJ genes, and laid a theoretical basis for further verification of their potential biological functions of VrJMJ genes.

ABSTRACT: Pigeons are known for their capacity to harbor and spread several zoonotic agents. Studies have suggested that pigeons are also relevant disseminators of multidrug-resistant strains. In this study, pigeons surrounding a veterinary hospital were sampled and tested for the presence of pathogenic Escherichia coli, Salmonella spp., Staphylococcus spp., and Clostridioides (Clostridium) difficile. E. coli isolates from 19 (40.4%) pigeons tested positive for the E. coli heat-stable enterotoxin 1 (EAST1)-encoding gene. The intimin-encoding gene (eae) of enteropathogenicE. coli (EPEC) was found in one isolate (2.1%). Salmonella spp. were found in nine (19.1%) pigeons, all from the first capture event (P < 000.1). S. Typhimurium and S. Heidelberg were isolated from six and three pigeons, respectively. Enterobacterial repetitive intergenic consensus (ERIC-PCR) of the Salmonella spp. isolates suggested that eight of the nine strains had a high genetic similarity, supporting the hypothesis of an outbreak of salmonellosis in these pigeons. Twenty (42.5%) staphylococcal isolates were recovered from 18 (38.3%) pigeons. Eight different species were detected, with S. xylosus being the most frequent. Two (4.3%) C. difficile strains were isolated. Three isolates, one each of S. Typhimurium, S. aureus, and C. difficile, were classified as multidrug-resistant strains.

Studies have suggested that pigeons are also relevant disseminators of multidrug-resistant strains. In this study, pigeons surrounding a veterinary hospital were sampled and tested for the presence of pathogenic Escherichia coli, Salmonella spp., Staphylococcus spp., and Clostridioides (Clostridium) difficile. E. coli isolates from 19 (40.4%) pigeons tested positive for the E. coli heat-stable enterotoxin 1 (EAST1)-encoding gene. The intimin-encoding gene (eae) of enteropathogenicE. coli (EPEC) was found in one isolate (2.1%). Salmonella spp. were found in nine (19.1%) pigeons, all from the first capture event (P < 000.1). S. Typhimurium and S. Heidelberg were isolated from six and three pigeons, respectively. Enterobacterial repetitive intergenic consensus (ERIC-PCR) of the Salmonella spp. isolates suggested that eight of the nine strains had a high genetic similarity, supporting the hypothesis of an outbreak of salmonellosis in these pigeons. Twenty (42.5%) staphylococcal isolates were recovered from 18 (38.3%) pigeons. Eight different species were detected, with S. xylosus being the most frequent. Two (4.3%) C. difficile strains were isolated. Three isolates, one each of S. Typhimurium, S. aureus, and C. difficile, were classified as multidrug-resistant strains. The present research suggested that pigeons residing in urban areas can act as reservoirs and disseminators of pathogenic bacteria, including nosocomial pathogens, such as diarrheagenicE. coli and multidrug-resistant Staphylococcus spp., C. difficile, and Salmonella spp.","PeriodicalId":10308,"journal":{"name":"Ciencia Rural","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67638457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT: This study developed chicken nuggets with emulsions with different percentages of canola oil (CO) to replace the chicken skin and evaluating the quality of the final product and the effect of frying. The experiment was set up in a 5x5 factorial scheme with the replacement of skin with different percentages of CO (0, 25, 50, 75, and 100%) and storage periods (0, 45, 90, 135,and 180 days), and parameters such as pH and oxidation were evaluated. It was considered a 5x2 factorial scheme (replacement of skin with CO and different sample conditions (raw and fried in CO)) for the analyses of the centesimal composition, fatty acid profile, atherogenic (AI), and thrombogenic (IT) indices. The sensory analysis evaluated the chicken nuggets at time zero. The pH values ranged from 6.62 to 6.86, as an effect of frying, there was an increase in lipid content with increasing levels of substitution (T0-raw: 5.36% and fried: 12.11%; T100-raw: 7.93% and fried: 15.43%) and a decrease in moisture content in relation to the raw sample. There was a decrease in AI (T0%-raw vs. T100%-fried, 0.39 vs. 0.10) and IT (T0%-raw vs. T100%-fried, 0.61 vs. 0.18) with CO addition and frying, and lipid oxidation increased with storage. The ω6/ω3 ratio decreased and the PUFA/SFA increased with the replacement of chicken skin with CO, but there was no difference in the sensory analysis. Even though chicken nuggets are prone to lipid oxidation, it is possible to improve their nutritional value either by adding CO to the meat mixture or by frying them.
摘要:本研究以不同比例菜籽油(CO)乳剂代替鸡皮制作鸡块，并对最终产品质量和煎炸效果进行了评价。实验采用5 × 5因子方案，分别采用不同CO含量(0、25、50、75、100%)和不同贮存期(0、45、90、135、180 d)的皮肤置换，并对pH、氧化等参数进行评价。它被认为是一个5x2的析因方案(用CO替换皮肤和不同的样品条件(在CO中生的和油炸的))来分析百分之一组成、脂肪酸谱、动脉粥样硬化(AI)和血栓形成(It)指数。感官分析在零时间对鸡块进行评估。pH值在6.62 ~ 6.86之间，随着替代水平的增加，油脂含量增加(生的5.36%，煎的12.11%;t100 -生的:7.93%，油炸的:15.43%)，水分含量相对于生样品有所降低。随着CO的添加和油炸，AI (t0%生对t100%煎，0.39 vs. 0.10)和IT (t0%生对t100%煎，0.61 vs. 0.18)降低，脂质氧化随储存而增加。用CO替代鸡皮，ω6/ω3比值降低，PUFA/SFA升高，但感官分析无差异。虽然鸡块容易发生脂质氧化，但可以通过在肉混合物中加入CO或油炸来提高其营养价值。

ABSTRACT: Sporotrichosis is a subcutaneous mycosis caused by fungus of the Sporothrix complex, and in Brazil the main species reported is Sporothrix brasiliensis, of which the diseased cat is the transmitter. Although, its occurrence has increased in the state of Paraíba, Brazil, since 2016, data on the disease in this state are limited. Therefore, this research aimed to identify molecularly isolates of Sporothrix spp. from domestic cats from cities in Paraíba, and in this way to expand the understanding of the disease in the state. Thirty-nine samples were analyzed, obtained from skin lesions of domestic felines, from the following cities in Paraíba: João Pessoa, Pilões, Patos, Areia, Bananeiras and Guarabira. Cytological analysis was performed to screen the samples, followed by fungal culture, and the molecular characterization of the isolates was performed, using the species-specific Polymerase Chain Reaction (PCR) or partial sequencing of the calmodulin gene. All isolates were identified as S. brasiliensis. The sequencing showed 100% similarity to the S. brasiliensis CBS 120339 strain. In view of this, it is concluded that in the study areas the species involved in cases of feline sporotrichosis is S. brasiliensis, its presence in Paraíba demonstrated the spread of the agent in regions distant from the epicenters in Brazil, alerting to the possible occurrence of zoonotic outbreaks similar to those found in the South and Southeast regions of the country. In addition, it highlights the emerging role of felines in the transmission of sporotrichosis in new endemic areas of Brazil.
摘要:孢子菌病是一种由孢子菌群真菌引起的皮下真菌病，在巴西报道的主要菌种是巴西孢子菌，病猫是其传播者。尽管自2016年以来，其在巴西Paraíba州的发病率有所增加，但该州有关该疾病的数据有限。因此，本研究旨在鉴定Paraíba城市家猫孢子丝菌的分子分离株，从而扩大对该州该病的认识。对来自Paraíba以下城市的39个家猫皮肤病变样本进行了分析:jo o Pessoa、Pilões、Patos、Areia、Bananeiras和Guarabira。对样品进行细胞学分析筛选，然后进行真菌培养，并使用物种特异性聚合酶链反应(PCR)或钙调素基因的部分测序对分离物进行分子表征。所有分离株均鉴定为巴西葡萄球菌。测序结果显示，该菌株与巴西孢子虫CBS 120339株的相似性为100%。鉴于此，我们得出结论，在研究地区的猫孢子虫病病例所涉及的物种是巴西孢子虫，它在Paraíba的存在表明该媒介在远离巴西疫源地的地区传播，提示可能发生与该国南部和东南部地区类似的人畜共患疾病暴发。此外，报告还强调了猫科动物在巴西新流行地区孢子虫病传播中的新作用。
