Abstract
The contemporary study examined the relative growth rate(RGR), and economic efficiency of Japanese quail as influenced by feeding regimens and dietary supplementation with Spirulina platensis (Arthrospira) (SP). A total of 324 Japanese quail chicks at one-week old were haphazardly divided into 12 treatment groups in a factorial arrangement (4×3), involving four feeding regimens (ad libitum, feeding on 85% of the requirements, ad libitum within 16 hours/ day and feeding on 85% of the requirements within 16 hours/day) and three levels of dietary SP supplementation (0, 0.5 and 1%). The obtained results revealed that relative growth rate (RGR) during 1-3, 3-6 and 1-6 weeks of age of growing quails were influenced significantly (Pad libitumwithin 16 hours/day groups showed the highest relative growth rate, during 1-6 weeks of age. However, feeding regimes on 85% req. and 85% within 16 hrs./day was more economic efficiency (%) than others groups. However, feeding regimes on ad libitum within 16 hours/ day was lowest economic efficiency(%) than others groups during 1-6 weeks of age. During 1-3, 3-6 and 1-6 weeks of age, quails fed on Spirulina platensis suppl.at level 0.5 % were higher insignificantly in relative growth rate than other treatment groups. Quails fed on un-supplemented with Spirulina platensis at level 1.0 % were lower insignificantly in relative growth rate than other treatment groups, during different period studies. On the other hand, birds feeding un-supplementation with seaweeds(Spirulina platensis) atlevel 0.5% were highest economic efficiency (%) than others groups. While, birds feeding supplementation with seaweeds (Spirulina platensis ) at 1.0% /kg die were lowest economic efficiency (%) than other groups. Quails fed feeding on ad libitum and ad lib. within 16 hrs./ day supplementation with seaweeds (Spirulina platensis ) at level 0.5% showed the highest relative growth rate, during 1-6 weeks of age. While, Quails fed feeding on 85% of the requirements within 16 hours/day supplementation with seaweeds (Spirulina platensis ) at 1.0% /kg diet were lowest economic efficiency (%) than other groups. However, FR on85% req. within 16 hrs/day without supplementation with seaweeds(Spirulina platensis) were highest economic efficiency (%) than other groups, during 1-6 weeks of age. In conclusion, the present study exhibits that quail could be kept under a feed restriction regimen, on ad libitumwithin 16 hours/day groups with seaweeds (Spirulina platensis) at level 0.5% showed the highest relative growth rate during 1-6 weeks of age than other treatment groups.
