The study was carryout to show the effects of layer age at (30, 34 and 38 weeks), egg storage period (2, 4, 6 days) their interactions on quality traits hy-line eggs. experiment included measurements characteristics in laboratory. Results from this were summarizing as: layers had significant effect (p ≤ 0.05) some eggs such weight, albumin yolk Haugh unit height; Also, unit, height.

The layer poultry is an important activity for food production with high biological value. Measuring egg quality has great relevance to ensure safety and products consumers. Thus, the objective was evaluate physical of four laying hen’s strains. Were used 864 eggs from hens’ lines (Hisex Brown®, Hy-Line Isa Label®, Lohmann Brown®). experimental design completely randomized composed treatments (...

AIM The present study was conducted to evaluate the performance of gray, brown, and white varieties of Japanese quail (Coturnix coturnix japonica) with respect to body weight, egg production, and egg quality traits in the coastal climatic condition of Odisha. MATERIALS AND METHODS A total of 500-day-old straight run Japanese quail chicks of three varieties, viz., gray, brown, and white were r...

BACKGROUND A six-week study involving two hundred and fifty (250) Harco Black layer birds at point of lay was conducted to investigate the effects of potential natural colorant on performance and Egg quality traits. The birds were assigned to five (5) dietary treatments, each containing supplements either of control, Baobab Leaf (BL), Waterleaf (WL), Red Pepper (RP), Canthaxanthin (CTX) at 40 g...

In this study, we attempted to enrich cyclo-His-Pro (CHP) using enzymatic hydrolysis of yeast and to evaluate the functionality of yeast hydrolysate (YH)-enriched CHP. Flavourzyme offered a better performance in enhancing CHP content than other proteases. The CHP enrichment conditions were optimized as follows: addition of 1% Flavourzyme, 48-h incubation at 60°C, and pH 6.0. The CHP content sig...

The quality of Pharaoh quail eggs obtained at 8, 13, 18 and 23 weeks of age was evaluated. Eggs laid by the oldest quail were characterized by the greatest weight (12.2 g), length (32.6 mm), width (25.8 mm) and shell surface area (25.3 cm2). The lowest shell weight was found in eggs from the youngest quail (0.9 g), and the lowest shell proportion (8.2%) was characteristic of eggs from the oldes...

Fast somatic growth is important considerations for successful and competitive aquaculture industry. In rainbow trout reared in South Korea, triploid induction was used to suppress negative influence of reproductive maturation body growth. However, the effects triploidy are visible both mature fish developing juvenile fish. Thus, it also explicate effect on during early-life stages trout-alevin...

In this work we have compared the absolute temperature data of the CMB spectrum with models of CMB spectra distorted by a single or two heating processes at different cosmic times. The constraints on the fractional energy injected in the radiation field, ∆ǫ/ǫi, are mainly provided by the precise measures of the FIRAS instrument aboard the COBE satellite, while long wavelength measures are cruci...
