SUBJECT: FEED PHOSPHORUS SHORTAGE
In the face of a 20-percent shortage of feed phosphorus that will take 6-18
months to correct, the National Research Council ' s COIIlIDittee on Ani mal Nutrition,
at the request of USDA, released an analysis of how much feeders and feed
manufacturers can cut back on phosphorus supplementation.
The committee said that the current shortage amounts to about 300,000 tons
of dicalcium phosphate equivalent. If feeders could cut back to current NRCrec01lllllended
levels, SOUle two-thirds of the shortage could be disposed of.
The report presents the current recOlmlendations by NRC and has established
two other levels of phosphorus feeding. One is a minimal leve l and the other
is an emergency level. Deficiency symptoms may occur if the latter is fed for
an extended period .
RECOMMENDATIONS FOR DAIRY CATTLE
The NRC phosphorus requirements for dairy cattle are based on data that
take into consideration variations among animals, herds, and feeds. Adherence
to these requirements should be maintained unless a shortage of inorganic
phosphorus sources necessitates a change. It should be recognized that the
phosphorus requirements are based , in large measure , on research conducted with
animals at lower levels of milk production. The phosphorus requirements of
high-producing dairy cattle have not been defined clearl y.
The NRC- recommended levels of phosphorus for animals under 100 k;*liveweight
have not been changed in this report, since these anima l s are fed milk

| Title | Dairy Herd Improvement Notes, April, 1974 |
| Series Designation | Dairy Herd Improvement Association Monthly Report |
| Description | The monthly report of the Dairy Herd Improvement Association (DHIA) was initiated by E.E. Anderson, Extension Dairyman in the 1940s. From the 1960s forward a cooperative report had been prepared jointly by staff members of the NMSU Dairy Department, Agricultural Engineering, Agronomy, Veterinary and sent primarily to dairy herds on test (OS, DHIA, DHIR), County Extension Agents, and Instructors of Vocational Agriculture. The publication of the DHIA report was overseen by Philip Leyendecker, a director of the NMSU Agricultural Extension Service in cooperation with U.S. Department of Agriculture. The title of the report had changed over time; it had a couple of variations, New Mexico Dairy Herd Improvement and Dairy Improvement Notes. This digital collection includes historical issues published between 1961 and 1980. |
