Gilt heat cycle chart
into heat or the induction of farrowing, so that the timing of service and sow throughput gilts are already cycling, PG 600 will not break the cycle and induce heat. readily available and farrowing can be better supervised (see Graph 1.). The first step in breeding a sow or gilt is for her to be sexually mature. Gilts typically reach puberty at around five months of age and at that time will begin to show signs of a heat cycle, also known as Estrous. While this age is typical for sexually maturity, it is not guaranteed as some do mature earlier or even later. Sows and gilts have an average 21 day heat cycle, although this can range from 17 to 25 days. An average animal in heat today will be in heat again in three weeks. This can be used to help synchronize farrowing dates in small herds so that animals are farrowing around the same time, and can be weaned of piglets (and therefore bred for their next litter) at the same time. Considering that a normal sow/gilt estrous cycle is 21 days, the anterior pituitary gland will secret FSH late in the estrous cycle at approximately days 18-20. LH is then secreted on days 0 – 2 of the cycle to cause ovulation to occur. The corpora lutea secrete progesterone. Progesterone is the primary hormone which maintains pregnancy.
The cycle of the gilt is regulated by hormones that act to control the follicular (days 14 to 21 of the cycle) and luteal (days 1 to 13 of the cycle) phases of the cycle. Follicles develop quickly in the last week before estrus and produce estrogen which is critical for events associated with expression of estrus, sperm transport and ovulation.

ATI ITCPH 202,068 views Investing time and talent in developing effective heat detection methods should be a top priority on every sow farm. Gilt development aside, this activity drives the flow throughout the pork production system. The pork industry is in dire need of stockmanship skills that will enhance heat detection and mating in the breeding herd. Conception rates of 75-85% are common, but rates of 90% or greater The gestation period of a gilt (meaning she has never farrowed, given birth) or sow (an older, “experienced” female) is three “3”s: Three months, three weeks, and three days. The months are 30 day months and not calendar months! This means that after the female has been bred, Gestation Period for Swine. The Gestation Period for Pigs is approximately 112-115 days from the first breeding. Pigs will not always conceive after one breeding. Hogs will generally mate multiple times in one cycle. The Pig Gestation Calculator above attempts to generalize the estimation of the due date. A normal heat cycle lasts approximately three weeks, within which the bitch will go through different stages. The Proestrus Stage — Getting Ready Lasting around 9 days, this first stage is marked by the eggs in the ovaries beginning to mature and the oestrogen levels start rising.

The total number of mounts by each herdmate was determined on day 10, day 15, day of heat, and day 5 of the next cycle. Herdmates varied in mounting activity, as did estrous cows in attracting mounts. More important, for the herdmates as a group, the number of mounts differed substantially with the day of the cycle. On average, dogs have two cycles a year. The estrus cycle lasts on average 12-21 days, but maybe be as short as a few days to four weeks. The estrus period length varies widely between breeds and individual dogs. The length of a cycle varies widely, even for dogs of the same breed.

Ovulation typically occurs at about two-thirds into an individual gilt or sow’s estrus (usually 30 to 40 hours after onset of estrus). The estrous cycle, or interval from estrus-to-estrus, typically averages 21 days and can also vary (18 to 24 days). KNOWLEDGE PRODUCTS - Heat Detection in Swine - Duration: 7:31.
