Canine distemper virus (CDV) is the causative agent of one of the most spread, highly contagious and lethal viral disease in canines, whose morbidity varies between 25-75% and mortality between 50-90%. The aim of the present study was to carry out an epidemiological study of CDV from a Veterinary Hospital in the city of Pachuca de Soto, State of Hidalgo. The information was obtained from 7280 medical records of canine patients treated during the 2017-2018 period, of which 65 met the positive case criteria for the CDV. An observational, cross-sectional epidemiological study with a retrospective search of cases was carried out. It was determined that 8 out of every 1000 patients attending the clinic were positive for CDV, observing that a higher frequency of males with 63%, with Relative Risk (RR) of 0.67 and an Odds Ratio (OR) of 0.47 , patients under 6 months have the highest frequency of cases with 62% (RR of 8.0 and OR of 19.2); Despite the variability of the breeds within the analysis performed, the highest frequency was found in mongrel dogs with 52% (RR of 1.79 and OR of 2.66), on the other hand, it was determined that seasonality influences the degree of presentation of this disease, being greater in winter with 45% of cases (RR 1.81 and OR 2.47). In conclusion, in the Veterinary Hospital under study, the CDV affects male Creole dogs less than seven months of age unvaccinated more and the disease occurs most frequently in winter

The objective was to evaluate the kinetics of degradation in the first compartment (C1) of llamas of the dry matter(DM) of forage F. dolichophylla harvested at 3, 6, 9, 12 and 15 weeks of growth during two seasons (rainy and dry ).The degradation kinetics of crude protein (PC), neutral detergent fiber (NDF) and acid detergent fiber (ADF) wereevaluated only in the rainy season. In situ degradation was described by the equation of Orskov et al., (1980) D = a +b (1-exp-ct). A completely randomized block design with a 2 x 5 factorial arrangement was used for the MS. The rate (c) 3.24% h-1, intercept of the curve (a) 22.22%, and the degradation potential of MS (a + b) 91.32%, were notaffected (P> 0.05) by the time, age and interaction. However, the effective DM degradation (estimated with a flowrate of k = 2% h-1) was affected (P 0.05) by the age of growth. However, the potentialand effective degradation (k = 2% h-1) was influenced by the age of growth, ranging from 97.7 to 90.1%, 86.0 to80.8%, and from 72.4 to 71.9% from 3 to 15 weeks of increase. The effective degradation of PC, NDF and ADF wasaffected (P <0.05) by the age of growth, decreasing from 88.6 to 63%, 63.5 to 57.1%, and from 51.7 to 40.3% from3 to 15 weeks of growth. It is concluded that the accelerated degradation of the protein at early hours, and lowdegradation of cell walls causes an imbalance in the availability of protein and absence of energy.
目的是评价大羊驼在生长3、6、9、12和15周的两个季节(旱季和雨季)中收获的草料圆叶菊(F. dolichophyla)干物质在第一室(C1)中的降解动力学。粗蛋白质(PC)、中性洗涤纤维(NDF)和酸性洗涤纤维(ADF)的降解动力学仅在雨季进行了评价。原位降解用Orskov et al.， (1980) D = a +b (1-exp-ct)的公式描述。MS采用2 × 5因子的完全随机区组设计，时间、年龄和交互作用对MS (A + b)降解潜能(A + b)的影响不显著(P> 0.05)， h-1率(c) 3.24%，曲线截距(A) 22.22%。然而，DM的有效降解(估计流速为k = 2% h-1)受生长年龄的影响(p0.05)。然而，潜在和有效降解(k = 2% h-1)受生长年龄的影响，在生长3 ~ 15周的范围为97.7 ~ 90.1%，86.0 ~ 80.8%，72.4 ~ 71.9%。PC、NDF和ADF的有效降解受生长年龄的影响(P <0.05)，生长3 ~ 15周时，PC、NDF和ADF的有效降解分别从88.6降至63%、63.5降至57.1%和51.7降至40.3%。由此得出结论，早期蛋白质的加速降解和细胞壁的低降解导致蛋白质的可得性和能量的缺乏不平衡。

The present research work was carried out in the Chirioco Canton Patamanta Community of the Municipality of Pucarani,with the objective of evaluating the effect of supplementation with beer and yellow corn on fattening of bulls grazedon native pasture, with three different rations during the time of transition (April, May and June). 9 Holstein mestizobulls of approximately 2 years of age have been used. The design used for increasing daily live weight and carcassperformance was randomized complete design. The average daily live weight increase was 1.21 kg for ration III), 0.99 kgfor ration II and 0.74 kg for ration I. The average requirement of the amount of water from a bull to produce 1 kg of meatwas of 95 L. The performance of the channel of bulls fed with different rations was 49.6%, 49.7% and 50.1% withrations I, II and III respectively. The reported values indicate that there are no significant differences, which can beattributed to the fact that the treatments were not homogeneous, since the bulls had a weight variation of 60 kg, as well asthe distance traveled for grazing.

El objetivo de la presente investigacion fue evaluar tres dosis diferentes de nitazoxanida en comparacion con el metronidazol para Giardiosis canina. En un total de 16 caninos comprendidos entre 3 y 4 meses de edad, los cuales fueron divididos aleatoriamente en 4 grupos asi: T0 (metronidazol 25 mg/kg BID por 5 dias, T1 (nitazoxanida 2mg/kg BID por 3 dias), T2 nitazoxanida (3 mg/kg BID por 3 dias) y T3 nitazoxanida (4mg/kg BID por 3 dias), y se determino la dosis eficaz de nitazoxanida y se comparo su porcentaje de eficacia con metronidazol. Se establecio el numero de quistes de Giardia spp. a traves del metodo de concentracion por flotacion de Willis, temperatura corporal, tiempo de llenado capilar (TLLC), prueba de pellizco cutaneo para determinar el porcentaje de deshidratacion de cada canino, asi como el analisis macroscopico de las heces (consistencia, color, olor, presencia de moco o sangre). Se realizo un analisis de covarianza (ANOVA) para la variable expulsion de quistes de Giardia spp. y un analisis de varianza para las demas variables, la comparacion de medias se lo realizo mediante prueba de Tukey al 5%. Los mejores resultados obtenidos fueron de T3 nitazoxanida (4mg/kg BID por 3 dias) con una eficacia de 97,9 % en comparacion con metronidazol que solamente obtuvo 67,8 % al final del tratamiento. En cuanto a la sintomatologia ningun individuo presento fiebre, las heces mejoraron en aspecto desde el dia 4 con una mejor resolucion en T3, se presento vomito al dia 2 solo en los individuos tratados con metronidazol, en cuanto al porcentaje de deshidratacion T1 obtuvo un 8% debido a que la resolucion de la diarrea tardo un poco mas a diferencia de los demas grupos. En esta investigacion no se encontro ningun efecto adverso del farmaco nitazoxanida.

En un total de 16 caninos comprendidos entre 3 y 4 meses de edad, los cuales fueron divididos aleatoriamente en 4 grupos asi: T0 (metronidazol 25 mg/kg BID por 5 dias, T1 (nitazoxanida 2mg/kg BID por 3 dias), T2 nitazoxanida (3 mg/kg BID por 3 dias) y T3 nitazoxanida (4mg/kg BID por 3 dias), y se determino la dosis eficaz de nitazoxanida y se comparo su porcentaje de eficacia con metronidazol. Se establecio el numero de quistes de Giardia spp. a traves del metodo de concentracion por flotacion de Willis, temperatura corporal, tiempo de llenado capilar (TLLC), prueba de pellizco cutaneo para determinar el porcentaje de deshidratacion de cada canino, asi como el analisis macroscopico de las heces (consistencia, color, olor, presencia de moco o sangre). Se realizo un analisis de covarianza (ANOVA) para la variable expulsion de quistes de Giardia spp. y un analisis de varianza para las demas variables, la comparacion de medias se lo realizo mediante prueba de Tukey al 5%. Los mejores resultados obtenidos fueron de T3 nitazoxanida (4mg/kg BID por 3 dias) con una eficacia de 97,9 % en comparacion con metronidazol que solamente obtuvo 67,8 % al final del tratamiento.

The production of ruminants, mainly cattle is estimated to grow from 1500 to 2600 million, as well as the population ofgoats and sheep (1700 to 2700 million), in the years 2000 and 2050. In Ecuador the production of ruminants is limited,availability of resources for education, learning problems in dry and tropical regions, the availability of grasses to covernutritional needs, not for animal information, in order to reduce the extensive grazing areas for feeding. The silvopastoralsystems, the use of post-harvest residues of crops of plant origin, are presented as a cost-effective alternative for sustain- able livestock production, due to the large quantity and quality of the biomass for use, throughout the year, even in timesdry. The foliar mass of trees, shrubs and residues are characterized by being rich in nutrients, however, as regards thepresence of metabolites, especially tannins, which decrease voluntary consumption, the digestibility of nutrients and theProduction of the animals, effects that are associated to the concentration in the diet and the quantity consumed, as wellas the state of health of the animal. Studies indicate that in moderate proportions (20-45 g kg-1 of dry matter) improve- ments in animal performance have been shown by reducing ruminal methanogenesis and degradation of forage protein inthe rumen. The (GHG), CO2 is the one that is in the highest amounts that currently is responsible for the increase inglobal warming compared to other greenhouse gases. The objective of the research is the contribution to knowledge, theuse of agricultural by-products, as well as the implementation of alternative systems in feeding and production of ruminants.
据估计，在2000年和2050年，反刍动物(主要是牛)的产量将从1500万头增加到26亿头，山羊和绵羊的数量也将从1700万头增加到27亿头。在厄瓜多尔，反刍动物的生产是有限的，教育资源的可用性，干旱和热带地区的学习问题，牧草的可用性以满足营养需求，而不是用于动物信息，以减少广泛的放牧饲养面积。利用植物源作物收获后的残茬，作为可持续畜牧生产的一种成本效益高的替代方案，被提出，因为全年，甚至在干旱季节，可供使用的生物质数量和质量都很大。树木、灌木和残叶的叶质量的特点是营养丰富，然而，就代谢物的存在而言，特别是单宁，会减少自愿消耗，营养物质的消化率和动物的生产，与饮食中的浓度和消费量有关的影响，以及动物的健康状况。研究表明，在中等比例(20-45 g kg-1干物质)下，通过减少瘤胃甲烷生成和饲料蛋白质的降解，动物生产性能得到改善。与其他温室气体相比，目前造成全球变暖的温室气体中，二氧化碳的含量最高。这项研究的目的是对知识的贡献，农业副产品的利用，以及反刍动物饲养和生产中替代系统的实施。
