Abstract :

Increase in feed prices in recent years has stimulated renewed interest in the area of feed restriction and simultaneously the birds have to provide space for feeding, watering and normal movements for their optimum growth and production. Thus, a great emphasis has been laid on feeding system, which
employs the use of quantitative or qualitative feed restriction. During growing phase 468 White Leghorn
(WLH) birds from random bred control population housed on deep litter housing system were exposed to three feeding regimes viz. T (ad lib.), T (Skip-two-days a week) and T (75% of ad lib.) on three different 1 2 3 stocking densities viz. S (2.5 ft /bird; 20 birds/pen), S (2.0 ft /bird; 25 birds/pen) and S (1.5 ft /bird; 33 1 2 3 2 2 2 birds/pen) to form nine combinations of feed regimes and stocking density. Between 20 to 32 weeks of age, T , T and T birds gained 31.76, 45.19 and 70.82 percent of body weight. The T ×S birds were heavier 1 2 3 1 3 (1904.5±39.9 g) than other groups at the end of laying phase. The maximum feed consumed by T group 1 (117.91±4.17 g) followed by T (116.61±3.80g) and T group (108.28±3.61 g), which differed significantly. 3 2 T ×S birds consumed daily about 102 g feed and was significantly lower from other interaction groups. The 1 3 birds kept under T ×S treatment gave maximum hen day egg production (64.36±6.78%) followed by T ×S 3 1 1 2 (63.83±0.28%) and T ×S (61.71±4.84%). Hen housed egg production followed almost the same pattern with 1 1 hen day egg production. Skip-two-days a week and 1.5-ft2/ bird treatment (T ×S ) produced eggs of 2 3 54.52±1.24 g weights, which were acceptable in market. It appears that skip-two-days fed birds reared on the density of 1.5 ft2/bird to be the most promising interaction group with respect to lower feed consumption during the laying period without any significant adverse effect on hen housed egg production. It appears that skip-two-days fed birds reared at the density of 1.5 ft2/bird to be the most promising interaction group with respect to lower feed consumption during the laying period.
