An Oriole bird feeder having a nectar reservoir with a base and a tapered port, and preferably a tapered port/perch assembly, is provided. The bird feeder allows Orioles and other similarly sized members of the Icterid family of birds to land on the perch and access the nectar in the reservoir base while, due to the diminishing taper of the opening in the tapered port, simultaneously preventing average sized Italian, Carniolan and Caucasian honey bees from entering the reservoir base through the port to obtain the nectar where they subsequently become trapped and perish.

This invention relates to a method for promoting growth of young chicken comprising the step; offering feed in a layered manner in subsequent order of pellet-size for adjusting the pellet-size to the size of the young chicken during a whole brooding cycle for the feed being attractive during the whole brooding cycle as perceived by the young chicken.

A cutting and threshing blade for a bush hog, wherein the blade has a trailing edge and a leading edge. At least a third of the leading edge of the upper-side of an elongate distal portion of the blade has a knife edge with a knife length that thickens toward the trailing edge. The trailing edge can have an upward air deflector. The bottom-side of the elongate distal portion has a threshing element, which includes a threshing block, which is a steel block having a block length that is comparable to the knife length and projects downward and substantially parallel to the knife edge. The rotating blades pummel growth carriers (i.e.; cob, husk) bearing seeds, grains, and kernels with enough force that they are released. The synergistic rotating knife edge and threshing block transform the bush hogging process from a cutting process to a cutting and threshing process.

Methods involve feeding young livestock animals a starter feed, where the starter feed comprises an amount of soluble mannan oligosaccharides. The young animals may be chicks. In response to ingesting the starter feed, the young animals may increase a rate of weight gain and increase feed efficiency.
