概括

这项研究确定了 Sunphase HT 植物酶的可用 (aP) 释放曲线,用于养高植物酸盐饮食的猪. 增加植物酶改善了猪生长,料效率和骨特性,为植物酶有效性建立了aP释放曲线.

科学领域:

动物营养和生理学
生物化学和新陈代谢

背景情况:

植物酸盐是植物性动物料中的反营养因素,减少 (P) 和其他矿物质的生物可用性.
植物酶在动物饮食中被广泛使用,用于化植物酸盐,释放P并改善营养利用.
了解特定植物酶产品可用的P (aP) 释放曲线对于精确的饮食配方至关重要.

研究的目的:

为了确定可用 (aP) 释放曲线,Sunphase HT 植物酶在养猪的食物中含有高酸盐度.
评估增加饮食可用的 (aP) 和Sunphase HT植物酶对猪生长性能和骨特征的影响.

主要方法:

总共有280头猪在21天的时间里接受了不同水平的单酸或Sunphase HT植物酶 (250-2,000 FTU/kg) 的食.
记录了增长性能参数,包括平均每日增长 (ADG),增长到养 (G:F) 和最终体重 (BW).
分析了骨,第十条肋骨和手指骨的骨特征 (骨灰重量,骨灰百分比和骨密度).

主要成果:

从单P增加食AP线性地改善了ADG,G:F和最终的BW.
用Sunphase HT植物酶补充剂线性增加了ADG,最终BW和血内醇,G:F的二次改善.
增加aP和植物酶补充剂线性或二次性地改善了各种骨特性,包括骨灰和骨密度.

结论:

太阳相HT植物酶有效释放可用 (aP) 在高植物酸盐的玉米-大豆-菜饮食猪.
对于Sunphase HT植物酶,生成的aP释放曲线是:aP释放 (%) = (0.360 × FTU) ÷ (2,330.250 + FTU).
植物酶补充剂提高了猪生长性能和骨发育,减少了对无机补充剂的需求.

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.

Roles of Electrolytes: Calcium and Phosphate

Roles of Electrolytes: Calcium and Phosphate

Calcium and phosphate are essential electrolytes in the human body, with calcium being the most abundant mineral. Around 99% of the body's calcium is stored in the skeleton and teeth, forming a crystal lattice of mineral salts in combination with phosphates. Calcium plays crucial roles in various bodily functions such as blood clotting, neurotransmitter release, muscle tone maintenance, and nervous and muscle tissue excitability.
The calcium concentration in blood plasma is primarily...

Hormones and Bone Tissue

Hormones and Bone Tissue

The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
