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.
Calving takes place in three stages. The initial stage of calving, when many of these signs first appear, can last between two and six hours. Once the water bag breaks, the second stage -- the actual delivery -- begins. For a heifer, or first-time mother, normal delivery lasts about an hour. Experienced cows might deliver in as little as a half-hour. If a heifer is still in labor after two hours, or a cow after an hour, call the vet. The third stage, expelling the placenta, should occur within 12 hours postpartum.
