概括
草显示为狗的可持续植物性蛋白质的承诺,可接受的营养结果高达10%的含量. 然而,由于营养物质消化能力降低,需要进一步研究以在猫饮食中获得最佳使用.
科学领域:
- 动物营养 动物营养
- 可持续的食物来源 可持续的食物来源
- 植物性蛋白质是一种植物性蛋白质.
背景情况:
- 草 (Lemna) 正在成为一种可持续的,高质量的植物性蛋白质来源.
- 关于其在物食中使用的研究有限,特别是对狗和猫的研究.
研究的目的:
- 为了评估含有蛋白在狗和猫饮食中对便质量,营养素消化能力和食感性的影响.
- 为了确定草蛋白是否是物料配方中豆蛋白的可行替代品.
主要方法:
- 在狗饮食 (0%, 5%, 10%) 和猫饮食 (0%, 10%, 15%) 中,豆蛋白取代了豆蛋白.
- 用2天的2碗测试对30只成年动物进行了评估.
- 在10天的时间内,对18只狗和21只猫进行了明显的全通道营养消化能力测量 (5天适应,5天收集).
- 便质量在1-5的尺度上得分.
主要成果:
- 与对照组相比,猫在10%的菜饮食中表现出更高的口感;在15%的含量中没有差异.
- 狗在5%和10%的菜饮食中表现出较低的口味,更喜欢对照饮食.
- 这两种物种都保持了可接受的便质量,包括子.
- 狗吃了5%和10%的草,对营养物质消化能力没有任何损害.
- 养10%和15%草的猫的干物质,蛋白质和能量消化能力显著降低.
结论:
- 在狗的饮食中,草蛋白是一种可行的替代品,可达到10%的含量,而不会对营养结果产生负面影响.
- 由于观察到的消化性问题,需要进一步的研究和开发,以优化猫咪饮食中草蛋白的含量.

Protein Digestion
Protein digestion begins in the stomach, where the highly acidic environment can easily disrupt protein structure by exposing the peptide bonds of polypeptide chains. After polypeptide chains are broken into individual amino acids by a series of digestive enzymes, the amino acids are transported to the liver via the bloodstream to produce energy.
Alternative RNA Splicing
Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...

Proteins: Dietary Sources and Requirements
Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...
