Case means form or variation.. Think of having a case of the flu: you are still yourself, but you are in a different form of yourself, so to speak, and you can only act in certain ways as a result of that state. Most Latin nouns, pronouns, and adjectives appear only in a limited number of different forms. For example, for the Latin word Ã¢la (wing), you will generally see only these forms: Ã¢la / Ã¢lae / Ã¢lam / Ã¢lÃ¢ / Ã¢lÃ¢rum / Ã¢lÃ®s / Ã¢lÃ¢s . Latin has several different boxes of endings.
And, cows that lose weight and body condition after calving have longer post-partum intervals. So with all that in mind, the postpartum interval, if conditions are ideal, for beef cows is between 50 and 60 days for an average of 55 days. First-calvers will be at least 10 days longer.
How long should a calving season last? The rule of thumb is 90 days to insure that all the cows calve within a year, but the length should be based on herd and management needs from manager time and marketing. The optimum calving season would have 60% of the cows calving in the first 30 days of the calving season. Conversion to a shorter calving season will highlight two things in the herd. First, less fertile cows can be identified and these freeloaders can be eliminated.
