Effects of Boric Acid and Humate Supplementation on Performance and Egg Quality Parameters of Laying Hens
In this study, the effects of boric acid and humate supplementation into hen diets on egg production and quality parameters and blood cholesterol levels were examined. For this aim, totally 160, 40 weeks of age, Hyline-White 98 layers were randomly divided into control and 3 treatment groups each containing 40 birds and 10 replicates (each with 4 birds). There was no boric acid or humate supple...
متن کاملLaying Performance and Egg Quality of Hens Supplemented with Sodium Bicarbonate During the Late Laying Period
This study was conducted to determine effects of dietary NaHCO supplementation on egg 3 production and egg quality during the late laying period. Hisex Brown layers, 54 wks of age, were blocked according to the cage location and then assigned randomly to receive one of four diets containing 0, 0.1, 0.2, or 0.4% NaHCO for 75 d. Each diet was replicated in 6 groups; each consisting of 2 cages con...
متن کاملEHects of dietary sodium bicarbonate on egg production and egg quality of laying hens during high summer temperature
Eggshell quality is one of the most common problems in layer stocks. Results from the field have shown that the incidence of cracked eggs in layer stocks ranges from 1-2% to 30-35% (ALTAN and ALTAN, 1992). This problem is more specific in older flocks when the birds were raised under high environmental temperatures. The eggshell consists of 98% calcium carbonate. The necessary Ca for shell form...
متن کاملEffect of Dietary Supplementation of Liquid Prebiotic and Antibiotic on Egg Production, Egg Quality, Blood Parameters, Immune System Response of Layer Hens at Post Molt Period
Extended Abstract Introduction and Objective: The inclusion of prebiotics in layer hen diets can act as a growth-promoting antibiotic replacer and have beneficial effects on egg production and egg quality. This study aimed to investigate the effects of liquid prebiotic on the post-molt laying performance, egg quality at different storage temperatures and times, immune system function, and bloo...
متن کاملEffects of Barley Cultivar and Dietary Supplemental enzyme on Performance, Egg Quality Traits, and Selected Blood Parameters of Laying Hens
The effect of supplementing two commercial multienzyme to diets included two barley cultivars (Sararood [71.99%] and Valfajr [66.39%]) on performance, egg quality, and blood parameters of laying hens was investigated in an 8-wk (65 to 73 wk of age) experiment. The commercial multienzymes were Grindazym™ (with mainly β-glucanase and xylanase activity) and Hemicell® (with mainly β-mannanase acti...
