the goal of this experiment was to investigating of effects of different levels of nano chromium (n-cr) in diet on egg quality and blood chromium content of japanese quail. two hundred and forty laying japanese quail (45 day old) were randomly distributed to 20 experimental unit with 12 birds in cage pens of 40 × 80 cm. experimental treatments include: 1) control national research council (nrc,...

an experiment was conducted to evaluate the effect of dietary crude protein and methionine levels on quality and quantity of egg production. fifteen diets formulated with 3 levels of protein (13, 14 and 15%) and 5 levels of methionine (0.25, 0.28, 0.31, 0.34 and 0.37%) and fed to 420 birds in a 3×5 factorial arrangement. each diet was randomly fed to 4 replicates of 7 birds each and fed for 3 p...

Rice bran (RB) is a major by-product, produced from the rice milling process. This study was conducted to evaluate the performance, egg quality, and blood biochemical parameters of 288 Hy-line laying hens fed diets with rice bran and commercial microbial phytase Natuphos®5000. The experiment was a 4×2 factorial one with four RB levels (0, 5, 10, and 15%) by two phytase levels (0 and 5000 FTU/kg...

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...

Enrichment diets high in ground flax may cause irritation to the gut, which may affect absorption of omega-3 polyunsaturated fatty acids (ω-3 PUFA) from flax as well as other dietary enrichment ingredients. This study assessed the egg enrichment with ω-3 PUFA and Lutein when provided alone in the diet, in combination, or when fed in alternate day patterns. A total of 144 individually caged Lohm...

this experiment was conducted to evaluate the effects of using rice bran, combo multi-enzyme and probiotic (protexin) in diet on performance, egg traits, biochemical parameters and blood cells of commercial laying hens. this experiment carried out using 384 hi-line (w36) laying hens in a completely randomized design as factorial (2×2×2) arrangement with two levels of rice bran (0 and 10%), two ...

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 goal of this experiment was to investigating of effects of different levels of nano chromium (N-Cr) in diet on egg quality and blood chromium content of japanese quail. Two hundred and forty laying japanese quail (45 day old) were randomly distributed to 20 experimental unit with 12 birds in cage pens of 40 × 80 cm. Experimental treatments include: 1) control national research council (NRC,...

The experiment was carried out to evaluate the effects of supplementing laying hen diets with different percentages of black tea factory waste (BTFW), evaluating performance, egg quality, yolk oxidation, and blood parameters. Twenty-four-week-old Lohmann layers (n=144) were divided into six dietary treatment groups (24 hens each), which were fed standard commercial diets supplemented with 0% (c...
