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.
Not an easy task to accomplish. Usually the length of the post-partum interval (PPI, time from calving to the first estrous cycle) is 45 to 55 days in beef cows. If cows are in good body condition at calving, then the PPI would be in the 45 to 50 day range and if in poor condition, the PPI would be longer.
