The food compositions for pigs contain calcium peroxide. Calcium peroxide is administered to the pigs via the oral route in a proportion of 0.02 to 1.3 % by weight of the total food ration. The percentage of lean meat and the quality of the carcasses are thus substantially improved.

Food compositions for pigs and processes for the feeding of pigs

Vinyl chloride and any other comonomers present in a vinyl chloride polymer are removed by heating the polymer to a temperature between its glass transition temperature and 180.degree. C. by directly condensing steam on to the polymer, maintaining the polymer at this temperature sufficiently long to remove the greater part of the monomer or monomers present in the polymer and then cooling the polymer to below its glass transition temperature by evaporating the steam that has condensed on the polymer.

Process for removing residual vinyl chlorine from the polymer

A composition for ingestion by ruminants to remove protozoa contains a peroxide of a metal of group 2 of the Periodic Table.

A process for the preparation of an aldonic acid from the corresponding ose, comprising enzymatically oxidizing the ose in a reaction mixture containing oxygen. The molar ratio of oxygen to ose in the reaction mixture is greater than 0.1.

Process for the manufacture of aldonic acids by an enzymatic method

A process for the preparation of coated seeds, in which the seeds are initially treated with an aqueous phase. The treated seeds are then coated with a coating agent containing a peroxide compound and a hydrophilic polymer, and the coated seeds are dried.

Process for the preparation of coated seeds

Process for removing the residual vinyl chloride monomer present after polymerisation in vinyl chloride polymers in the form of an aqueous dispersion which is heated to a temperature at least equal to the glass transition temperature of the polymer and subjected to stripping by an inert fluid while being maintained at a temperature at least equal to the glass transition temperature of the polymer.
