Renco Lean-Meater® SERIES 12
“Ultrasound for Ultra Profits”® (假一罰十)
The Lean-Meater Series 12 is a microprocessor controlled A-Mode ultrasonic instrument. It is designed to measure the total thickness of the skin and up to three layers of back fat. When the measurement is complete, the instrument will display the number of fat layers detected and the total thickness in millimeters with a greater accuracy than ever before.The Series 12 has a number of new features. Two of the most significant are the automatic detection of the number of layers present and the display of the result.
The primary use is the measurement of back fat in swine for the determination of sow condition, gilt selection, quality and other genetic aspects. Other uses include fat measurement in cattle, sheep and other land animals, as well as blubber measurement in aquatic animals. (The Lean-Meater is not intended for measurement of muscle tissue.)
The Lean-Meater can be thought of as an electronic ruler. Ultrasonic pulses sent into the animal are reflected back to the instrument from tissues of interest. The times until these echoes are received are translated into distances in mm. Measurements are non-invasive—no piercing of the skin with the consequent danger of infection. The animals are neither hurt nor irritated.
The use of LED’s (Light Emitting Diodes) assures sharp, crisp, readings. Only the Lean-Meater uses an LED display which will operate over a wider range of temperature and be more visible under adverse light conditions.
The instrument features rugged all-metal construction and a Nickel Metal Hydride—“green”—rechargeable battery, which does not need to be recycled. Battery charging and low power indicators are also provided.
The instrument is fast. Measurements are made quickly and easily as follows:
Simply wet the test site (usually by the last rib) with a coupling fluid, such as cooking oil, press the button to turn the instrument on and apply to the test site. Move it around to remove air bubbles. The display locks in when the total depth and number of layers has been determined. Note the reading on the display, which from left to right, shows the number of fat layers detected and the digital reading of total thickness of skin and fat layers. The figures below illustrate various displays.

背膘不理想的解決方案：
1、后備母豬150日齡時(shí)，測(cè)背膘，12-14mm。低于10mm，增加飼料能量。
2、體重不足100公斤，B點(diǎn)背膘低于下限（12 mm），則增加營(yíng)養(yǎng)濃度。
3、B點(diǎn)背膘接近上限或高于上線（14mm）應(yīng)該減少營(yíng)養(yǎng)濃度。
4、經(jīng)產(chǎn)母豬（斷奶如果B點(diǎn)背膘低于16mm或者B點(diǎn)背膘高于23mm的）按母豬飼養(yǎng)七階段精細(xì)化飼養(yǎng)。
