概括

确定产卵 (Gallus gallus domesticus) 的最佳饮食可用 (AP) 是卵质量和产量的关键. 0.38%的AP水平最能支持蛋生产和料效率.

科学领域:

动物营养动物营养
禽畜科学禽畜科学禽畜科学
鸟类生理学鸟类生理学

背景情况:

可用的 (AP) 对于产至关重要,影响蛋的完整性和生产力.
了解最佳的AP水平对于高效的家禽养殖和蛋生产至关重要.

研究的目的:

为了确定10-16周的产卵的最佳饮食可用 (AP) 水平.
评估不同AP水平对蛋特性,血清酸酶 (ALP) 和整体性能的影响.

主要方法:

一项完全随机的设计研究涉及375只产,它们的食量为0.25%至0.45%的AP.
评估了性能指标,包括料摄入量,料转换率 (FCR),蛋质量 (EM) 和蛋产量 (EP).
用断线模型分析蛋特征和血清ALP度,以确定AP需求.

主要成果:

饮食AP水平没有显著影响料摄入量,FCR,EM或EP百分比.
蛋宽度,蛋体积和外厚度显示出对增加AP水平的显著线性反应.
血清ALP度随着AP的上升而非线性下降,表明ALP的估计需求为0.357%.
对FCR,EP和ALP的最佳AP水平分别估计为0.374%,0.383%和0.357%.

结论:

约0.38%的可用含量是最大限度地提高产卵量和料利用率的最佳水平.
这种AP水平还支持理想的蛋质量和生理指标,如血清ALP.
这些发现为制定用于商业产卵生产的实用饮食提供了宝贵的见解.

The Phosphorus Cycle

The Phosphorus Cycle

Unlike carbon, water, and nitrogen, phosphorus is not present in the atmosphere as a gas. Instead, most phosphorus in the ecosystem exists as compounds, such as phosphate ions (PO43-), found in soil, water, sediment and rocks. Phosphorus is often a limiting nutrient (i.e., in short supply). Consequently, phosphorus is added to most agricultural fertilizers, which can cause environmental problems related to runoff in aquatic ecosystems.
