Description

Technical Field

[0001] The utility model relates to the technical field of cow breeding, in particular to a modular TMR and digestive tract linkage screening device. Background Art

[0002] In modern animal husbandry, especially in cow farming, the quality and digestibility of total mixed rations (TMRs) are key factors affecting cow production performance. TMR sieves and digestibility analysis sieves are two specially designed tools for evaluating and optimizing the quality and digestibility of cow feed. TMR sieves are mainly used to analyze the particle size distribution of feed. By using sieves with different apertures, a reasonable mixing ratio of roughage and concentrate in the feed can be ensured, thereby improving the cow's feed intake and feed conversion efficiency. The digestibility analysis sieve is used to evaluate the cow's digestion of feed. By separating the feed residues in the feces, the cow's digestion ability of different feed components can be intuitively observed, and the feed formula can be adjusted to optimize the cow's nutritional intake.

[0003] However, existing TMR screens and digestion analysis sieves have some defects in practical applications, which limit their further application in animal husbandry. First, existing screening devices are often complex in structure, and the installation and disassembly process is cumbersome, which is not conducive to the rapid screening and analysis of feed and feces. In addition, the cleaning and maintenance of traditional screening devices are relatively difficult, and they are easily contaminated by feed residues and feces, affecting the screening efficiency and accuracy. Finally, the existing technology lacks modular design and cannot achieve rapid switching between TMR screening and digestion screening, which limits the versatility and applicability of the screening device.
