Sequential feeding using whole wheat and a separate protein-mineral concentrate improved feed efficiency in laying hens.

The effect of feeding nutritionally different diets in sequential or loose-mix systems on the performance of laying hen was investigated from 16 to 46 wk of age. Equal proportions of whole wheat grain and protein-mineral concentrate (balancer diet) were fed either alternatively (sequential) or together (loose-mix) to ISA Brown hens. The control was fed a complete layer diet conventionally. Each...

Effect of Wet Feeding on Feed Conversion Efficiency in Laying Hens during Summer Season

The aim of this study was to investigate the effect of wet feeding on feed conversion efficiency in laying hens during summer season. The study was carried out on 192 pullets of eight weeks age (distributed to four groups). The feed offered to chicks consisted of starter diet up to 8 weeks of age and grower diet up to 20 weeks of age. From 20 weeks onwards, birds were provided with layer diet u...

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...

Modulation of energy and protein supplies in sequential feeding in laying hens

Sequential feeding (SF) consists of splitting energy (E) and protein/calcium (P) fractions temporally, improving the feed conversion ratio (FCR) of hens compared with a continuous distribution during the day. In a previous study, the E fraction (with a low level of protein) was provided in the morning, whereas the P fraction (with low level of energy) was given in the afternoon. However, there ...

feeding whole wheat with or without a dietary enzyme or grit to laying hens

a 3*2*2 factorial experiment was conducted to study the effect of feeding whole wheat (0, 10, and 20%), a microbial enzyme source (arabino-xylanase based enzyme for wheat at 0% and 0.1%) and 0% or 1% insoluble grit (number 3 layer size) on the performance of white leghorn hens at 19 to 54 weeks of age. each dietary treatment was replicated four times with ten hens, housed two to a cage, eac...
