G77-355 A Guide For The Control Of Flies In Nebraska Feedlots And Dairies (Revised March 1990), John B. Campbell Jan 1977

G77-355 A Guide For The Control Of Flies In Nebraska Feedlots And Dairies (Revised March 1990), John B. Campbell

Historical Materials from University of Nebraska-Lincoln Extension

Flies, especially stable and house flies, can create serious and costly problems for feedlot and dairy operations. This publication describes several methods for control.

Several species of flies may be in confined livestock facilities during summer. The stable and house fly are the most serious pests. Blow flies also may be present if molasses is in the diet. Horn flies--small blood-feeding flies--may be present in early spring. These flies overwinter as pupae in or near manure pats in range or pasture. If cattle are not present in the grassland when horn flies emerge, they will migrate to confinement cattle. Normally ...

Four procedures for pork carcass evaluation are given here, along with illustrations.

Pork carcass value is an important factor affecting the profitability of the pork industry. Reproduction traits and growth performance are easily recognized as keys to the profitability and health of the pork industry, yet carcass value also plays an important role. Differences in carcass product value are monetarily recognized by recognizing differences in carcass weight and grade. In addition, the pork industry recognizes that consumption of pork may key on public health concerns relating to reducing fat consumption and the resulting consumer demand for lower fat products.

Nebraskans are concerned about declining water levels in some domestic and stock wells.

Nebraskans are concerned about declining water levels in some domestic and stock wells. Drought and irrigation well development have been major factors. Water level declines have been especially pronounced during the pumping season in places where the aquifer is artesian or confined (a confined aquifer is also referred to as an artesian aquifer). Many domestic and livestock pumps may have to be set deeper in order to yield water. In nearly all cases water levels recover rapidly when the pumping season ends. Large water-level fluctuations are normal ...
