Abstract
This invention provides a feedstock for controlling hypocalcemia in prepartum dairy cattle. An essential feature of the feedstock is a dietary cation-anion difference (DCAD) with a value between about −5 and +20 meq/100 g dietary DM. Other essential features are a weight ratio of potassium:magnesium between about 3-5:1, and between about 1-12 g/kg dietary DM of omega-6 fatty acid derivative having rumen-bypass properties.
Claims18
A feedstock for controlling hypocalcemia in prepartum dairy cattle which comprises a supplemented basal ration having a prescribed content of nutrients comprising (1) macromineral proportions as defined by a dietary cation-anion difference (DCAD) which corresponds to the equation:
- DCAD=meq(Na++K+)−(Cl−+SO4−2)/100 g dietary DM
- where meq is milliequivalents, Na is sodium cations, K is potassium cations, Cl is chloride anions, SO4 is sulfate anions, and DM is dry matter;
- wherein DCAD has a value between about −5 and +20 meq/100 g dietary DM;
- and wherein the feedstock has a weight ratio of potassium:magnesium between about 3-5:1;
- and (2) between about 1-12 g/kg dietary DM of omega-6 fatty acid derivative having rumen-bypass properties.
A dietary supplement adapted for incorporation in ruminant feedstock for control of hypocalcemia in prepartum dairy cattle, wherein the supplement is formulated to provide macromineral cations and anions and omega-6 fatty acid derivative having rumen-bypass properties, and wherein the supplement comprises the following parts by weight of ingredients:
- Chloride-containing 10-30 Sulfur-containing 0-50 Magnesium-containing 5-30 Omega-6 fatty acid 50-120 derivative-containing.
A method for controlling hypocalcemia in prepartum dairy cattle which comprises feeding a prepartum cow with a feedstock comprising a supplemented basal ration having a prescribed content of nutrients comprising (1) macromineral proportions as defined by a dietary cation-anion difference (DCAD) which corresponds to the equation:
- DCAD=meq(Na++K+)−(Cl−+SO4−2)/100 g dietary DM
- where meq is milliequivalents, Na is sodium cations, K is potassium cations, Cl is chloride anions, SO4 is sulfate anions, and DM is dry matter;
- wherein DCAD has a value between about −5 and +20 meq/100 g dietary DM;
- and wherein the feedstock has a weight ratio of potassium:magnesium between about 3-5:1;
- and (2) between about 1-12 g/kg dietary DM of omega-6 fatty acid derivative having rumen-bypass properties.
