As the spring calving season begins to wind down on farms across the country, many farmers will now begin planning for the breeding season. The Irish Cattle Breeding Federation ICBF has released its breeding guidelines for springwhich outlines six steps for farmers to follow for a more successful breeding season. Possible strengths and weaknesses to consider include: milk production; fertility; calving performance; beef; cow maintenance; cow management; health. Image source: ICBF. Nationally, farmers tend to use a sufficiently large team of bulls. The common mistake made by many is that individual bulls in the team can be overused.

Description The willow flycatcher Empidonax traillii breeds across much of the conterminous United States and in portions of extreme southern Canada. As might be expected in such a wide-ranging species, willow flycatchers in different portions of the range exhibit differences in appearance, song, and ecological characteristics.
The intent of this chapter is to provide information on the breeding-season ecology of the southwestern subspecies, E. However, most ecological studies to date have dealt with other willow flycatcher subspecies. Relatively few studies have been published on E. Publication Notes You may send to rmrspubrequest fs.
