تاثير سطوح مختلف كلسيم و فسفر به همراه ويتامين D3 و عصاره رازيانه بر عملكرد و ويژگي هاي كيفي تخم مرغ در مرغان مادر گوشتي پس از تولك بري

Effect of Different Levels of Calcium, Phosphor and Vitamin D3 with Fennel Extract on, Performance and Egg Shell Quality in Post Molted Ross Broiler Breeders

هدف اين آزمايش مقايسه اثر سطوح مختلف كلسيم، فسفر، عصاره رازيانه و ويتامين D3 بر صفات عمل كردي، ويژگي هاي كيفي پوسته تخم مرغ در مرغ مادر گوشتي سويه تجاري راس 308 از هفته 96 تا 102پس از تولك بري بود. هر پن شامل ده قطعه مرغ و يك قطعه خروس بود. اين آزمايش به صورت يك طرح كاملاً تصادفي شامل هفت تيمار (سطوح مختلف كلسيم، فسفر به همراه ويتامين D3 يا عصاره رازيانه) در چهار (پن) تكرار انجام شد. عصاره رازيانه (50 ميلي گرم/كيلوگرم) اثر معني داري بر توليد تخم مرغ، وزن توده تخم مرغ، تخم مرغ هاي قابل ارسال به جوجه كشي، كيفيت پوسته، درصد سفيده و افزايش وزن پرنده داشت (0/05

The purpose of this experiment was to compare the effects of calcium, phosphorus, and fennel extract (FE) and vitamin D3 on performance and egg shell quality in post molted Ross broiler breeders from 96 to 102 weeks. Each pen consisted of 10 hens and 1 rooster. This experiment was done in a completely randomize design with seven treatments (different levels of calcium, phosphorus plus fennel extract or vitamin D3) that each treatments assigned to 4 replicates. The addition (50 mg/kg diet) FE had significant affection egg production, egg mass, settable egg, shell quality, relative albumin weight and body weight gain (p<0/05). The results of this experiments showed that decrement of the calcium and phosphorus up to 10 percent, did not significantly affection indicated parameters (p>0/05), but lower levels of calcium and phosphorus (20%) significantly affect these parameters (p<0/05). Supplementation of vitamin D3 to the diet with 10 percent less calcium and phosphorus could increase egg production and percentage of settable eggs. Additionally, when calcium and phosphorus was 10 percent lower than control diet, supplementation of FE increased egg production and percentage of settable eggs but this effect did not was the same as vitamin D3.The results of these experiments indicated that supplementation diet with FE had significant affect when diets contain 10 percent lower in calcium and phosphorus.
