Ostrich meat: Production,quality parameters,and nutritional comparison to other types of meats

The poultry industry is considered one of the most efficient industries in producing animal protein. Poultry production consists of several main segments: broilers, commercial eggs, turkeys, ducks, and other poultry, including geese, guinea-fowl, pheasants, quail, and ratites. Currently, ostrich meat is marketed as a healthy red meat because it is characterized by high polyunsaturated fatty acid contents, low saturated fatty acid content, and low cholesterol level compared with red meats, such as beef, while tasting similar to lean beef. Ostrich meat contains lower sodium and higher iron contents than other kinds of meat, making it preferable to hypertensive people and those with anemia. Taken together, ostrich meat is considered as an ideal red meat for individuals seeking healthier lifestyle. Moreover, many different ostrich products, such as leather and feathers, are used by people. The current review paper considers the quality characteristics of ostrich meat, including physical traits, and compares it to other types of meats, such as bovine and other poultry meats.     

MAGNETIC RESONANCE IMAGING OF THE CANINE OPTIC NERVE

We describe the magnetic resonance (MR) imaging aspects of normal canine optic nerve, the diameter of the optic nerve as measured on MR images, and optimal MR sequences for the evaluation of the optic nerve using a 0.2 T MR unit. Three millimeter contiguous slides of the normal canine orbital region were acquired in transverse and dorsal oblique planes using a variety of tissue weighting sequences. It was apparent that detailed anatomic assessment of the optic nerve can be performed with low‐field MR imaging, but none of the sequences provided unequivocal superior image quality of the optic nerve. The mean diameter of the optic nerve sheath complex was 3.7 mm and of the optic nerve 1.7 mm. The intraorbital and intracanalicular parts of the optic nerve are consistently visible and differentiation between the optic nerve and optic nerve sheath complex is possible using low‐field MR systems.     

温热环境对育肥猪体温调节的影响规律

环境温湿度是影响育肥猪福利、生长及健康的重要因素。猪属于恒温动物,当环境温湿度发生变化时,可以通过调整自身的产热量、采食量、呼吸频率、皮肤温度及体核温度等指标来维持产热和散热的平衡,从而在一定温湿度范围内维持体温的恒定。本文总结和分析了育肥猪在不同环境温湿度条件下体温调节指标发生剧烈变化的顺序,判断不同温度下育肥猪的舒适状态,为今后研究、建立猪舒适环境参数,科学调控猪舍内的温热环境提供参考。     

Courses for horses: Rethinking the use of proton pump inhibitors in the treatment of equine gastric ulcer syndrome

Oral omeprazole has been the cornerstone of equine gastric ulcer syndrome (EGUS) treatment for nearly 20 years. However, approximately 15–30% of equine squamous gastric disease (ESGD) cases and 75% of equine glandular gastric disease (EGGD) cases fail to heal within current treatment guidelines. Recently, a number of factors that may affect the efficacy of oral omeprazole have been highlighted and the pharmacodynamics of a number of novel proton pump inhibitors (PPIs) have been described in the horse. The purpose of this article is to review the factors that affect oral omeprazole efficacy, with the goal of maximising therapeutic response, and the novel PPIs recently described.     

免疫抑制对苏拉灭和贝尼尔治疗小鼠伊氏锥虫病疗效的影响

用从自然感染宿主分离的伊氏锥虫原种ＪＧ的克隆ＪＧｍｃ１和ＪＧｍｃ５感染免疫活性正常小鼠和免疫抑制小鼠，２４ｈ后，以苏拉灭或贝尼尔治疗，两种药物对免疫抑制小鼠的ＣＤ１００均明显高于免疫活性正常小鼠，由经受一次苏拉灭或贝尼尔治疗未愈的免疫抑制小鼠分离的锥虫，感染免疫活性正常小鼠，再用原来对该克隆感染的免疫活性正常小鼠ＣＤ１００的苏拉灭或贝尼尔治疗即无效。用免疫溶解试验分别测定一组免疫抑制和免疫活性正确     

高温条件下复合抗应激剂对肉鸡的影响

本文研究了高温条件下复合抗应激剂对肉鸡的影响。结果表明：经历３２ ℃一周的５ ～８ 周龄肉鸡采食量、增重、饲料转化率均显著下降（Ｐ＜ ０ ．０１） ,饮服复合抗应激剂显著改善增重和饲料转化率（Ｐ＜ ０ ．０１） , 采食量未见明显改变,饲料转化率达到常温水平。３２ ℃１６ 小时血浆皮质酮、Ｔ３ 显著下降（Ｐ＜ ０ ．０１） 、Ｔ４ 显著升高（Ｐ＜ ０ ．０１） ;３２ ℃１２０ 小时血浆皮质酮、Ｔ３ 升高并超出常温组（Ｐ＜ ０ ．０５） 、Ｔ４ 较１６ 小时下降但仍高出常温组（Ｐ＜ ０ ．０５） 。饮服复合抗应激剂时血浆皮质酮、Ｔ３ 、Ｔ４ 显现相同变化规律,但这种变化得到显著缓解     

黄土丘陵区白羊草与达乌里胡枝子混播草地土壤呼吸日变化特征

土壤呼吸是反映土壤质量和肥力性状的重要指标,阐明禾―豆混播草地土壤呼吸作用的变化规律及其影响因素,可以为准确评估混播草地的环境效应及响应提供依据。在2011和2012年6月份,采用动态密闭气室分析法,比较了白羊草(Bothriochloa ischaemum)与达乌里胡枝子(Lespedeza davurica)不同比例间作混播草地总土壤呼吸速率的日变化特征、混播植物贡献率以及温度敏感性等。结果表明,不同混播比例草地的总土壤呼吸速率日变化为单峰型曲线,峰值出现在12:00~14:00。总土壤呼吸速率日均值高低顺序为单播白羊草白羊草和达乌里胡枝子间作单播达乌里胡枝子。不同间作比例草地的总土壤呼吸速率与白昼气温相关显著(P0.05),而与5、10和15 cm土层白昼土壤温度关系不明显;单播条件下,白羊草草丛的土壤呼吸对温度的敏感性高于达乌里胡枝子;各草地土壤呼吸Q10值的变化范围为1.48~2.61,以单播白羊草最高,单播达乌里胡枝子和两者间作混播草地间无显著差异(P0.05)。     

羊传染性胸膜肺炎防治

羊传染性胸膜肺炎是一种高度接触性传染性疾病,致病原是肺炎支原体。妊娠阶段的母羊受到病原侵染后表现为流产产下死胎,并表现出明显的繁殖障碍。近年,此病发生率逐年升高,造成的死亡现象不断增强,严重威胁养殖产业健康发展。作为养殖管理人员,应从该种疾病的流行病学、临床表现、病理变化和诊断方法等多角度入手,构建针对性的防治措施,严格落实预防为主的原则,为提高养殖效益奠定坚实的技术支撑。该文主要探讨羊传染性胸膜肺炎的防治过程。     

重庆市近郊区县鸭传染性浆膜炎病病原分离鉴定及防治

通过对重庆近郊的沙坪坝区、北碚区、九龙坡区、永川市、璧山县、铜梁县的7个养鸭场病死鸭的病原分离,分离到三株细菌,经染色镜检、生化鉴定、动物回归实验,确诊为鸭里氏杆菌。药敏试验结果显示对庆大霉素、青霉素、链霉素、土霉素等高度敏感。在临床上交替使用这些药物,收到较好治疗效果。将分离菌制成灭活苗免疫1周龄的健康鸭,20日龄时用分离菌进行攻毒,平均保护率达83.3%。
