A COMPARISON OF ISOTOPE DILUTION AND WEIGH-SUCKLE-WEIGH METHODS FOR ESTIMATING MILK INTAKE BY PIGS

Comparison of weigh-suckle-weigh and machine milking for measuring ewe milk production.

Thirteen crossbred ewes were used to compare weigh-suckle-weigh (WSW) and machine milking (MM) methods for determining milk production of ewes that were rearing single or twin lambs. At parturition, ewes were 13 mo of age and produced six single lambs and seven pairs of twin lambs. Milk production estimates were initiated on d 6 of lactation and a 3-d rotation of the two techniques was implemen...

A modification to the isotope-dilution technique for estimating milk intake of pigs using pig serum.

The aim of this study was to compare the measurement of deuterium oxide (D2O) directly in pig serum with that in sublimed whole blood. This was to assess whether excluding vacuum sublimation before analysis would cause any significant loss of accuracy in estimates of pig milk intake. Water and serum standards were made in deionized water and serum, respectively, and were assayed with samples un...

Measurement of milk intake by deuterium dilution.

In 14 studies, each lasting seven days, on eight bottle fed infants milk intake was measured by deuterium dilution and by weighing the formula consumed and oral losses. Mean (SD) milk intake was 829 (108) g/day when measured by isotope dilution and 837 (98) g/day when measured by direct weighing, giving a mean difference between methods of 1.0 (5.0)%. Thus the stable isotope procedure is a pote...

Weigh Scale Applications for the MCP3551

In the case of Figure 1, the bridge is said to be fully active. In some cases, only half of the bridge may be active (half active). For some sensors, only a single element of the bridge may change in response to the stimulus. This application note will focus specifically on load cells, a type of strain gauge that is typically used for measuring weight. Even more specifically, the focus will be ...
