为加快天津畜牧业粪污治理进程,提高治理成效,本文采用问卷调查和实地走访,对天津畜牧业粪污治理情况进行深入调研。目前天津畜牧业粪污治理面临的困境主要有:规模化养殖场距离居民区近,土地消纳能力不足;畜禽养殖小区多,粪污治理难度大;散养户排在粪污治理工程之外,但散养模式短期内不会立即消失;粪污治理重在"治",种养结合不紧密,粪污深度资源化能力低。为突破上述困境,应打破区域观念,畜禽养殖有选择地逐渐外移;实现畜禽养殖与环境容量相匹配,大力发展种养结合农牧循环模式;鼓励规模养殖场建立有机肥厂,向产业融合发展;提高畜牧生产水平,将生态功能放在天津现代畜牧业发展的重要位置;加快养殖小区的牧场化改造进程,对散养实行因地制宜的政策。本研究对促进天津畜牧业发展方式转变,改善生态环境,建设新农村和美丽乡村具有重要的现实意义。 相似文献

随着养殖业的不断壮大,养殖污染已成为备受人们关注的一大社会问题。推广种养结合型农业循环生产模式,不仅能有效地解决养殖污染问题,保护农业生态环境,还可促进农业增产、农民增收,加快农村全面奔小康的进程。本文就张浦叶茂生态农牧场已初步形成的"种养结合型"资源生态循环利用的生产模式进行了剖析,以供今后制定循环农业决策时参考。 相似文献

A prebreeding examination should be performed on animals of both sexes to ensure their optimal health at the time of breeding. At this time, the medical and reproductive histories should be reviewed to detect potential negative influences upon the reproductive tract. Serologic testing for canine brucellosis should be performed to detect and remove infected animals from the breeding program. Examination of the female reproductive tract may be limited to the caudal vagina, vestibule, and vulva. Defects that cause pain and reluctance to breed may be detected with thorough digital and visual inspection. The male reproductive tract can be examined along nearly its entire length without special techniques. Semen may be collected for initial evaluation of testicular function and fertility. Swelling of the vulva and a hemorrhagic vaginal discharge will alert the observant owner to the onset of proestrus. Vaginal cytology may be examined every few days after the observed onset of proestrus to determine the onset of estrus. Breeding should be performed by natural or artificial insemination every 2 to 4 days during estrus to achieve optimal conception rates. The bitch should not be exhibited or trained during the period of potential pregnancy. Unnecessary drugs should not be administered. A diagnosis of pregnancy may be made by abdominal palpation 28 to 30 days after the last breeding. Serum progesterone levels may be measured if pregnancy is not established to determine if ovulation occurred and if sufficient levels of progesterone are present to maintain pregnancy. Optimal breeding management techniques can often result in the maximum reproductive efficiency desired. 相似文献

高山细毛羊是在海拔2600~3500m的祁连山高寒牧区育成的我国第一个高原型毛肉兼用细毛羊品种,它是以新疆细毛羊、高加索细毛羊为父本,以当地西藏羊、蒙古羊为母本,经过杂交改良、横交固定、选育提高3个育种阶段培育而成的。甘肃高山细毛羊以其优良的高原抗逆性而著称,并于1995年被列入《世界动物品种志》; 相似文献

A comprehensive understanding of behavioral-gonadal-endocrine interrelationships is a prerequisite for the effective management of any feline breeding program. Some of the topics discussed in this article are seasonality of breeding behavior, problems associated with copulation, suggested mating schemes, and pharmacologic control of reproductive cyclicity. 相似文献
