|II. How livestock enterprises improve the profitability of farming systems|
Milk production and sales that are continuous through the year provide a cash flow to farmers that is critically needed to cover on going farm expenditures in seasons when there are no crop/annual sales.
Since meat animals (male animals and less productive females) are a separate source of income to milk production, these sales constitute still further diversification in income, as well as increasing total amount. Furthermore, the labor requirements for livestock enterprises are well distributed throughout the year and thus largely avoid adding to peak labor problems related to crop production.
