Feed Conversion and Feeding Behaviour in Laying Hens
T_e high proportion of feed costs in total operating expenses (1,2,6) indicates that the utilization of feed by the birds is closely related to the profitability of >oultry operations. The relationship between feed conversion (expressed as a ratio between weight units of feed consumed per weight unit of product) and profitability (defined as an increment .of total income over total costs) is es...
متن کاملLathyrus cicera as quality feed for laying hens
Introduction Research at CLIMA has indicated that Lathyrus cicera and L. sativus (grasspea) have potential as grain legumes on 100 000 to 300 000 ha of neutral to alkaline soils in low-to-medium rainfall areas of southern Australia. They do not have serious disease problems and are envisaged as low maintenance/low cost crops for the purposes of green manure, managing herbicide resistant weeds, ...
متن کاملFeed preference in pigs: relationship with feed particle size and texture.
In previous studies, we observed important differences in the feed preferences of pigs resulting from changes in only 1 dietary ingredient. The present experiment was conducted to study the relationship between the feed preference values of feeds reported previously and their particle size and texture characteristics. The effect of individual feed ingredients was studied when added to a common ...
متن کاملEvaluating by-products of the Atlantic shellfish industry as alternative feed ingredients for laying hens.
A full-cycle laying hen study was conducted to evaluate crab meal (CM) and lobster meal (LM) as feed ingredients for laying hens by assigning four hundred thirty-two 35-wk-old White Leghorns to 1 of 6 diets [control, 2.5% CM, 2.5% LM, 5% CM, 5% LM, and 2.5% CM + 2.5% LM (blend)]. Productive performance and egg parameters were evaluated every 28-d period. Eggs were collected at 67 wk of age from...
متن کاملAssessment of lighting needs by W-36 laying hens via preference test.
Light intensity, spectrum and pattern may affect laying hen behaviors and production performance. However, requirements of these lighting parameters from the hens' standpoint are not fully understood. This study was conducted to investigate hens' needs for light intensity and circadian rhythm using a light tunnel with five identical compartments each at a different fluorescent light intensity o...
