ABSTRACT Protozoa of the genus Cryptosporidium are parasites capable of causing animal rearing losses due to diarrhea outbreaks. This review aimed to determine the prevalence of and potential risk factors for bovine cryptosporidiosis in Brazil. The search was carried out in the databases Science Direct, Scopus, Web of Science, and SciELO. The search strategy used the descriptors “Cryptosporidium,” “cryptosporidiosis,” “cattle,” “calves,” and “Brazil.” Nine studies conducted in different Brazilian states between 2008 and 2019 were selected. The age of the evaluated animals ranged from 0 to >36 months. The main risk factors were the low age of the animals, collective pens, presence of diarrhea, contact with other animals, and dairy breed. The average prevalence rate was 30.51%. The species identified were C. ryanae, C. parvum, and C. bovis. Optical microscopy was used as a diagnostic method for oocysts in fecal samples and to determine the species, and PCR was used in three studies. The average prevalence of Cryptosporidium spp. in cattle in Brazil was 30.51%, ranging from 10.2 to 62.5%. The main risk factors found were young animals, the presence of animals with diarrhea, contact with other animals, dairy breeds, and collective pens.

ABSTRACT This study aimed to analyze the seasonal variation of gastrointestinal parasitic infections in goats and sheep in São Luís, Maranhão, Brazil. Fecal samples were collected directly from the rectal ampulla of the animals to count the eggs per gram in the feces at 30-day intervals over the 12-month study period. This study included 40 small ruminants, comprising 22 goats (14 sows, 6 kids, and 2 sires) and 18 sheep (13 sows, 4 lambs, and 1 sire). The study assessed the variation in the excretion of gastrointestinal nematode eggs during the dry and rainy seasons. Coproculture was performed to identify third-stage larvae. In the 12 months of research and monthly sample collections, 95.9% and 82.3% of the eggs detected were endoparasites in the fecal samples of the goats and sheep, respectively. Eimeria spp. oocysts were present in 50.6% and 30.4% of the goat and sheep fecal samples, respectively. The results indicated that the mean number of eggs per gram of feces was higher in the rainy season than in the dry season in both goats and sheep. The genera of gastrointestinal nematodes identified via monthly coproculture tests were Haemonchus sp., Trichostrongylus sp., and Oesophagostomum sp. Thus, gastrointestinal nematode parasitism was higher in goats and sheep during the rainy season than in the dry season, and the genera Haemonchus sp. and Trichostrongylus sp. were the most prevalent.
摘要:本研究旨在分析巴西马拉尼赫州 o Luís山羊和绵羊胃肠道寄生虫感染的季节变化。在12个月的研究期间，直接从动物的直肠壶腹收集粪便样本，每隔30天计算粪便中每克鸡蛋的数量。研究对象为40只小型反刍动物，包括22只山羊(14头母猪、6只幼崽和2只母羊)和18只绵羊(13头母猪、4只羊羔和1只母羊)。该研究评估了胃肠道线虫卵在旱季和雨季的排泄变化。共育鉴定第三期幼虫。在12个月的研究和每月取样中，山羊和绵羊粪便样品中检出的虫卵分别为95.9%和82.3%的内寄生虫。山羊和绵羊粪便中分别检出50.6%和30.4%的艾美耳球虫卵囊。结果表明:山羊和绵羊的平均每克粪便产蛋数在雨季均高于旱季;通过每月共养试验鉴定出胃肠道线虫属为血线虫属、毛圆线虫属和食道口线虫属。因此，雨季山羊和绵羊的胃肠道线虫寄生率高于旱季，其中血线虫属和毛圆线虫属最为普遍。

ABSTRACT This research aims to describe the cost-benefit analysis of selective therapy adoption for clinical mastitis based on the identification of pathogens using on-farm culture system. A survey of clinical mastitis cases was carried out in the database of a dairy herd with 500 lactating Holstein cows, during the period of September 2017 to October 2019. Variables such as frequency of cases, main pathogens identified, costs with antibiotic therapies and milk disposal were evaluated and compared between one year before (P1) and after (P2), the farm's selective therapy adoption. During the study period, 599 cases of clinical mastitis were identified, 361 in P1 and 238 in P2. The average cost of therapies was US74.33 and US91.82 for P1 and P2. Considering the two years of the study, the estimated cost of treating clinical mastitis was US45,444.31, of which US$27,559.97 were spent in P1 and US17,884.34 in P2. Based on the result of the identification of the pathogen types associated with clinical mastitis, selective therapy demonstrated cost reduction already in the first year of implementation.

ABSTRACT The objective of this work was to characterize the internal temperature of the carcass, pH and sarcomere length in four categories of body weight at a slaughter. The categories were: category 1, animals up to 1.5 kg, category 2, animals from 1.501 to 2.5 kg, category 3, animals from 2.501 to 3.5 kg and category 4, animals over 3.501 kg. The time intervals evaluated were 0.5, 2, 4, 6, 8, 10, 12, 14, 16, 18, 24 and 36 hours after bleeding, therefore, a factorial scheme (4 x 12) was used, in which where four categories of pre-slaughter weight and the behavior of the carcasses during the post-slaughter time were evaluated. There was no interaction effect between the weight categories and the time for the variation of the carcass internal temperature, pH and sarcomere length, but when only the time of rigor was evaluated, there were significant differences for the analyzed parameters. The internal temperature of the initial average carcass (0.5 hours) was 16.02°C, reaching 3.80°C at 36 hours post-slaughter. In addition, the lowest average pH found was at 24 hours, with a value of 5.39. Regarding the sarcomere length, the smallest mean length observed was 1.41 µm at 16 hours post-slaughter and the final mean length (36 hours) was 1.89 µm. It was concluded that the analyzed margin of the categories of body weight at slaughter did not interfere in the variation of temperature, pH and sarcomere length during the post-mortem of the Pantanal caiman.
本研究的目的是表征屠宰时胴体内部温度、pH值和四类体重的肌节长度。分类为:1类动物1.5公斤以下，2类动物1.501至2.5公斤，3类动物2.501至3.5公斤，4类动物3.501公斤以上。评估的时间间隔为出血后0.5、2、4、6、8、10、12、14、16、18、24和36小时，因此，使用了一个因子方案(4 x 12)，其中评估了屠宰前体重和屠宰后时间内胴体的四类行为。胴体内部温度、pH值和肌节长度变化的时间与体重类别之间无交互作用，但当仅评估僵硬时间时，分析参数存在显著差异。初始平均胴体内部温度(0.5小时)为16.02℃，屠宰后36小时达到3.80℃。24小时pH平均值最低，为5.39。关于肌节长度，屠宰后16小时观察到的最小平均长度为1.41µm，最终平均长度(36小时)为1.89µm。结果表明，屠宰时体重类别的分析裕度对潘塔纳尔凯门鳄死后温度、pH值和肌节长度的变化没有影响。

ABSTRACT The objective of this study was to characterize the milk production in the central Amazonian region of the state of Amazonas. A questionnaire, consisting of objective questions, was applied to a sample of 50 properties located in the municipalities of Careiro da Várzea and Itacoatiara. The studied mesoregion develops an extensive dairy cattle breeding, where most of the producers have low schooling (60%), did not receive financing or financial incentive (70%) for the development of the dairy activity, nor are they engaged in associations or cooperatives (96%). Manual milking occurs in 100% of the analyzed properties, only once a day, with only 10% performing hygiene procedures in milking. The average production identified in the region was 3. 5L/cow/day. The uncontrolled natural mount is the only way used in the reproductive management of the properties. The current production is diversified in cattle and bubaline mixed-race (90%). In this region all the owners make use of native pastures. This region develops an extensive dairy cattle ranching, and the efficiency of the production system is limited due to inadequate sanitary, reproductive and food management, which favors low animal productivity.
本研究的目的是表征亚马逊州中部亚马逊地区的牛奶生产。对位于Careiro da Várzea和Itacoatiara市的50处房产进行了问卷调查，其中包括客观问题。所研究的中区域发展了广泛的奶牛养殖，其中大多数生产者受教育程度低(60%)，没有为发展乳制品活动获得融资或财政激励(70%)，也没有参加协会或合作社(96%)。人工挤奶发生在100%的分析属性，每天只有一次，只有10%的人在挤奶时执行卫生程序。该地区确定的平均产量为3。5 l /牛/天。不受控制的自然坐骑是对这些财产进行繁殖管理的唯一方法。目前的生产是多样化的牛和bubaline混合品种(90%)。在这个地区，所有的主人都使用原生牧场。该地区发展了广泛的奶牛牧场，由于卫生、繁殖和食品管理不足，导致动物生产力低下，生产系统的效率受到限制。

ABSTRACT The aimed of this study to assess the productivity and nutritional characteristics of hydroponic corn forage derived from bico de ouro creole seeds and AL-Bandeirante. Two treatments (T), each representing a corn seed variety, were randomly allocated to beds filled with a wood sawdust substrate: T1 (n=5) - bico de ouro creole seed variety, and T2 (n=5) - AL-Bandeirante hybrid seed variety. On the 13th day, forage was collected to assess seedling biometry, green and dry mass production, and bromatological analyses. The data were subjected to statistical analysis, with a 5% significance level. The creole seed variety yielded higher seedling height (17.53 cm), root length (10.19 cm), stem (5.37 cm), leaf (12.17 cm), and greater production of green mass (7.22 kg/m²) and dry matter (2.05kg/m²) (P<0.05). The AL-Bandeirante corn forage had higher dry matter content (39.18%), mineral matter (2.33%), non-fiber carbohydrate (31.88%), and estimated total digestible nutrients (68.14%) (P<0.05), while the creole corn forage had higher organic matter content (99.45%), ethereal extract (19.53%), neutral detergent fiber (45.56%), and cellulose (15.46%) (P<0.05). Crude protein, acid detergent fiber, and lignin were similar between the treatments (P>0.05). Despite the AL-Bandeirante variety yielding a higher concentration of certain nutrients, its forage productivity was significantly low. Therefore, under the conditions of this study, the use of the creole seed variety is recommended.
摘要:本试验旨在研究以bio de ouro creole种子和AL-Bandeirante种子为原料的水培玉米饲料的产量和营养特性。两个处理(T)，每个处理代表一个玉米种子品种，随机分配到填充木屑基质的床上:T1 (n=5) - bico de ouro creole种子品种，T2 (n=5) - AL-Bandeirante杂交种子品种。第13天采集草料，进行幼苗生物特征、青干量产和色相分析。对数据进行统计学分析，显著性水平为5%。克里奥尔种子品种的苗高(17.53 cm)、根长(10.19 cm)、茎长(5.37 cm)、叶长(12.17 cm)更高，绿质量(7.22 kg/m²)和干物质(2.05kg/m²)的产量更高(P<0.05)。AL-Bandeirante玉米饲料具有较高的干物质含量(39.18%)、矿物质含量(2.33%)、非纤维性碳水化合物含量(31.88%)和估计总可消化营养素含量(68.14%)(P<0.05)，而creole玉米饲料具有较高的有机质含量(99.45%)、空灵提取物含量(19.53%)、中性洗涤纤维含量(45.56%)和纤维素含量(15.46%)(P<0.05)。粗蛋白质、酸性洗涤纤维和木质素在不同处理间差异无统计学意义(P>0.05)。尽管AL-Bandeirante品种的某些营养物质浓度较高，但其饲料生产力明显较低。因此，在本研究条件下，推荐使用克里奥尔种子品种。
