       4 . The composition of  claim 3 , wherein the ratio of b) to c) is from 1.5:1 to 2.8:1.  
   
   
       5 . The composition of  claim 1 , wherein the C2-C6 mono-hydroxy alcohol is present in an amount from 2% to 5%.  
   
   
       6 . The composition of  claim 1 , wherein the emulsifier is a non-ionic surfactant.  
   
   
       7 . The composition of  claim 1 , wherein the viscosity of the composition is from 1000 cP to 10000 cP at 0 degrees C.  
   
   
       8 . The composition of  claim 1 , wherein said composition adequately disperses into water within 2 minutes when added at a ratio of composition to water of from 1 g/kg to 100 g/kg.  
   
   
       9 . The composition of  claim 1 , wherein said composition adequately disperses into water within 20 seconds when added at a ratio of composition to water of from 1 g/kg to 100 g/kg.  
   
   
       10 . The composition of  claim 1 , wherein the C1 to C6 alkyl lactate is ethyl lactate.  
   
   
       11 . The composition of  claim 1 , wherein the C2 to C6 mono-hydroxy alcohol is propanol.  
   
   
       12 . A food additive comprising the composition of  claim 1 .  
   
   
       13 . A water-dispersible liquid vitamin composition comprising. 
 a) from 40% to 90% by weight of the composition of a vitamin component dissolved in from 1% to 12% by weight of the composition of an oil, the vitamin component being selected from the group consisting of. 
 (i) a precursor of vitamin A;  
 (ii) a precursor of vitamin E;  
 (iii) a mixture of a precursor of vitamin A and a precursor of vitamin E;  
 (iv) a mixture of a precursor of vitamin A and a precursor of vitamin D3;  
 (v) a mixture of a precursor of vitamin E and a precursor of vitamin D3;  
 (vi) a mixture of a precursor of vitamin A, a precursor of vitamin E and a precursor of vitamin D3;  
   b) from 2% to 10% of C1 to C6 alkyl lactate;    c) from 0% to 10% of a C2 to C6 mono-hydroxy alcohol;    d) from 5% to 50% of one or more veterinarily acceptable emulsifiers;    wherein the composition is substantially free of water.    
   
   
       14 . A water-dispersible liquid vitamin composition comprising. 
 a) from 40% to 90% by weight of the composition of a vitamin component dissolved in from 1% to 12% by weight of the composition of an oil, the vitamin component being selected from the group consisting of: 
 (i) retinyl propionate;  
 (ii) dl alpha tocopheryl acetate;  
 (iii) a mixture of retinyl propionate and dl alpha tocopheryl acetate;  
 (iv) a mixture of retinyl propionate and vitamin D3;
