High impact information on WHC

Average daily gain, IMF percentages, and water-holding capacity (WHC) were also determined [1].
Where a bulk constraint operates intake is calculated as constrained food intake (CFI) where (where WHC is the water-holding capacity of the food (kg water/kg dry food) and Cwhc is the animal's capacity for WHC (units/kg live weight per d)) [2].
Water-holding capacity was lowered (P < .01) in all halothane genotypes due to elevated preslaughter muscle temperatures [3].
Water-holding capacity was higher (P < .05) and Hunter L*-values lower (P < .05) is dantrolene-treated pigs than in the control animals.(ABSTRACT TRUNCATED AT 250 WORDS)[4]
Selection for increased LMA and(or) decreased BF using US is, however, expected to result in decreased IMF and WHC, increased percentage of LM water and shear value, and in decreased juiciness, tenderness, and pork flavor [5].

Other interactions of WHC

Selection for increased ADG is expected to improve WHC but to decrease the percentage of LM water, with an associated decrease in juiciness [5].

Analytical, diagnostic and therapeutic context of WHC

Across the six limiting feeds, scaled intakes in the final 5 d of each period, when the pigs were in equilibrium with their feeds, were directly proportional to the reciprocal of the water-holding capacities (WHC) of the feeds, as measured by a centrifugation method [6].
