“…Inclusion of moderate prelay Ca may help create better body Ca reserve than low prelay Ca (1.0%). Leeson and Summers (2008), Bouvarel et al (2011) and Sujatha and Rajini (2015) suggested 2.0-2.5% prelay Ca agrees with the present findings. Low prelay Ca of 0.9-1.5% causes a negative Ca balance in hen (Bouvarel et al 2011).…”

“…The 18.0% prelay CP (T4 and T5) significantly (p<0.05) increased pullets daily PI (Table 2) than 16.0% prelay CP (T0 and T1, T2 and T3). Results corroborate with the findings of Sujatha and Rajini (2015) recommended 18.0% prelay CP produced a pullet with better body protein before sexual maturity than 16.0% prelay CP. The higher PI at the beginning of the laying period might be required to produce larger eggs and to compensate BWG (Soares et al 2003).…”

“…Adoption of proper nutrition needs to produce pullets that develop into profitable layers. Earlier studies suggest no beneficial effect by feeding highnutrient-density diets during the laying period, but during the prelay period (Sujatha and Rajini, 2015). Based on the metabolic changes before onset of egg production, a lowdensity BIS (2007) diet during growing, may not support a present high-yielding layer to establish essential reservoirs.…”

Background: Transitional phase of 2-3 weeks (prelay) before onset of egg production is extremely important for efficient layer. This study evaluates different nutrient density prelay diets on the subsequent performance of White Leghorn layers. Methods: Total 180, 16-week-old White Leghorn pullets assigned to six-prelay feeding strategies (kcal ME per kg/%CP/%Ca) during 16-18 weeks. Treatments were T0 (BIS control-2500/16.0/1.0), T1 (2700/16.0/1.0), T2 (2700/16.0/2.0), T3 (2700/16.0/2.5), T4 (2700/18.0/2.0) and T5 (2700/18.0/2.5). Subsequently, pullets were fed with same layer diet (2600/18.0/3.0) during 19-40 weeks. Various growth and production parameters were recorded. Result: The 18% CP (T4 and T5), 2.0-2.5% Ca (T2 to T5) and 2700 kcal ME/kg (T1 to T5) in prelay diet significantly increased pullets daily metabolic energy (p less than 0.05), protein (p less than 0.05) and calcium (p less than 0.01) intake during 16-18 weeks than 2600 kcal ME/kg (T0), 16.0% CP (T0 to T3) and 1.0% Ca (T0). Prelay diet (T5) improved egg number, per cent egg production, feed efficiency, performance efficiency index and egg feed price ratio without affecting weight gain and feed consumption suggesting that prelay diet is a compromise between grower and layer diets.

“…In egg-laying hens, the period around the beginning of the egglaying phase constitutes a critical moment for the subsequent productive performance of the hen (Sujatha & Rajini, 2015). Two to three weeks before laying the first egg, there is a significant increase in the weight gain of the egg-laying hens that seek to accumulate body reserves to support the production and size of the eggs during the egg-laying cycle (Summers, 1993).…”

A total of 320 13-weeks-old pullets were weighed and randomly allocated to treatments comprised by four levels of crude glycerin (0, 3, 6 or 9%) and two levels of ME (metabolizable energy, difference of 100 kcal/kg) in the diets growing (14 to 17 weeks of age), pre-lay and pre-peak (low: 2750, 2800 and 2750 kcal/kg and high: 2850, 2900 and 2850 kcal/kg, respectively). During the study, body weight was registered until 30 weeks of age, feed intake, egg weight and egg-production for each repetition and for individual hens were measured every week. The information was analyzed through a completely randomized design with a 4x2 factorial arrangement. During the growing phase, hens that received low energy diets consumed more feed (p<0.05), gained less body weight (p<0.05) and recorded lower feed conversion (p<0.05). Besides, a positive linear effect (p<0.05) was observed when including glycerin on feed conversion and weight gain. During the initial egglaying phase, hens fed low-energy diets consumed more feed (p<0.05) and laid lighter eggs (p<0.05). Furthermore, a positive linear effect (p<0.05) of including crude glycerin on egg yield and feed intake was observed. After the egg-laying peak, the hens of high energy groups consumed 1.6 g/d less feed (p<0.05) and lay 0.9% less eggs, also, it a quadratic effect of inclusion of glycerin on laying-eggs was observed. In conclusion, the use of high energy diets decrease feed intake, increase egg weight until peak, but decrease the percentage of eggs post-peak; glycerin used in diets increases feed intake and improves egg-laying rate in different ways during the laying phase.
