Calves weaned at 3 weeks were fed exactly the same in these two trials. In addition, calves were fed a high quality, free-choice calf starter (22% protein on a dry matter basis) with special attention to assisting calves to eat if they had not begun consuming starter by 5 days of age.

A Petrochemical Product. Although PVC can be produced from a range of hydrocarbons including coal, and derivatives of plants such as sugar cane, the bulk of world production is currently manufactured using the chemical compound ethylene.Ethylene (or ethene) which has the chemical formula C2H4, is a product of the oil & gas industry.PVC is therefore considered to be a petrochemical product.At the start of the ethylene-based PVC production process, the ethylene is combined with chlorine to produce an intermediate chemical known as EDC (ethylene dichloride or 1,2-dichloroethane).he chlor-alkali (caustic soda) industry is often located together with petrochemical complexes or near deposits or rock salt. VCM plants, which use ethylene and chlorine as major raw materials, and PVC plants, are generally located in petrochemical complexes due to this background.
