6. Pregnancy During the first 5 months of pregnancy, the decline in milk yield in pregnant cows is similar to the equivalent lactation period in non-pregnant cows. However, following the fifth month of pregnancy, cows begin to decline more rapidly in milk yield. The average gestation period of dairy cows is 283 days Sow herd management is generally broken into the three phases of a sow's life gestating a litter, nursing a litter and not pregnant but getting ready for the next litter. The longest of the three phases gestation could arguably be the most critical phase.

In animals such as the rabbit or pig, which bear many young at a time, gestation is shorter for larger litters than for smaller ones.

Experimentally infected kittens developed diarrhea 5-6 days after inoculation. Reactivation can occur years after an animal was infected. Clinical Sign Animals that are too hot will pant and lay on their side, perhaps appearing lethargic. When they are too cold they will huddle and tend to lay on their stomach with their feet underneath them. Heat stress. Because a gestation facility houses sows in various stages of pregnancy, it needs to be designed to prevent heat-stress 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. I have some forage that is a summer annual and I tested it for nitrates.

Not every avian eggs hatch in 21 days. See the chart below for incubation periods for other fowl. The duckbill platypus is the only mammal that lays eggs and they have an incubation period of 12 days. Never incubate the eggs of wild birds; these chicks will not live without their mother's care if they do hatch A female opossum may have 1-3 litters per year. During the mating season, the male attracts the female by making clicking sounds with his mouth. The female opossum is a spontaneous ovulator with an estrous cycle of about 28 days. She is in estrus a short period, about 36 hours. This is the time mating can occur calculated fertile period. When using chilled (extended) or frozen semen, or a stud dog with compromised semen quality, breedings should occur on the most fertile days (days 4,5 and 6 post LH surge). Gestation length is also determined by the date of the LH surge.
