what is farrowing in agriculture



Farrowing is a time of high risk for sows. It has been observed that 42% of sow deaths occur during the peripartum period, and an additional 16.5% of sow death loss occurs during lactation. 6 During the peripartum period, sows are prone to specific disease conditions, such as mastitis and metritis, that may lead to lactation insufficiency.

The process of birthing a litter of pigs is called farrowing. Sows are moved to the farrowing barn a few days before their expected due date. There, they are housed in individual farrowing pens which provide them with comfort and privacy for their arriving litter.


What is the process of farrowing?

K.A. Schat, in Encyclopedia of Agriculture and Food Systems, 2014 Vaccines for Swine. The intensive swine industry uses several production systems, but all consist of farrowing, nursery, growing, and finishing units, with the latter two frequently combined into one unit.On some farms, all units are used in a continuous production system, preventing the use of an all-in/all-out …

Farrowing begins with some biological communication between the sow and the piglets. Pressure and hormones from the piglets and the placenta tell the uterus that the maximum capacity has been reached and it is time to bring the piglets into the …

What is the meaning of furrow in agriculture?

Most confinement operations place the sow in a farrowing pen or crate which restricts her movement to protect her baby pigs. Farrowing and lactation occur in the same facilities until the baby pigs are weaned. An average sow will raise three to five litters of pigs in her lifetime. Pigs are born with sharp teeth and curly tails.

How to tell if a pig is farrowing?

Frequent observations of the sow before farrowing should enable the signs of impending farrowing to be detected. General examination may include measuring body temperature; it normally increases above 39°C 24 to 48 hours before the birth of the first piglet and heart rate peaks before and during parturition. Nesting behaviour is greatest 6 to 12 hours before the first piglet is born. Palpation of the mammary gland for the composition and presence of colostrum, which normally runs freely during parturition, appearing first in the cranial pair of the mammary glands some hours before beginning of parturition. After the onset of the second stage of labour and as it progresses, the number of piglets born, as well as their vitality and uniformity, should be assessed (Oliviero 2010 ).

How many piglets will a sow farrow?

A majority of sows will farrow at least 5 piglets and expel the placentas soon after the last piglet is born.

What are the two watchwords regarding obstetric intervention in sows?

The two watchwords regarding obstetric intervention in sows are gentleness and lubrication. Violation of either of these principles can result in significant injury to the genital tract. Such injury may further decrease the probability of liveborn piglets and most certainly results in suffering for the sow. Farrowing attendants with small hands and arms have a distinct advantage when assisting sows with dystocia. Smaller hands can manipulate a fetus with greater dexterity in the limited space of a sow’s genital tract and are likely to induce less traumatic injury to the sow.

Do farrowing houses have obstetrics?

Each farrowing enterprise should have a standard protocol in place for obstetric intervention. Although farrowing house personnel are expected to have primary responsibility for attending and assisting sows during parturition, the attending veterinarian should understand and have previously reviewed the protocol for that farm. This is especially important if the protocol includes the use of veterinary prescription drugs, such as oxytocin. Protocols may be individualized for each farrowing unit and should take into account the abilities and training of farrowing house personnel, the welfare of the sow, and the economic realities of intervention strategies.

Why is farrowing a problem?

However, allowing the sow more freedom to perform motivated behaviours often results in increased crushing of piglets and hence a piglet welfare problem. Although alternative farrowing systems exist, a major barrier to the uptake of these systems is that they must deliver acceptable levels of piglet mortality. Research efforts have led to successful development of loose farrowing systems delivering high performance and high welfare. The key to success has been recognising that allowing the display of species-typical behaviours contributes to the biological fitness of the animal, which encompasses important economic performance parameters including number of offspring produced, viability of offspring and maternal rearing ability. Further welfare challenges have developed as sows have been subject to genetic selection pressure for leanness and prolificacy. A more balanced equation where the cost of maternal investment (for instance shoulder lesions, loss of body condition, lower residual reproductive output and thus shorter longevity) is balanced against the increase in the number of piglets born and weaned, is needed as a basis for breeding programs. Therefore system design optimisation must be accompanied by optimisation of both human inputs (i.e., through augmentation of management) and animal inputs (i.e., through appropriate genetic selection strategies).

Why use farrowing crates?

The use of farrowing crates and creep escape areas to minimize crushing injuries

How does a farrowing crate help pigs?

The other perceived advantage of the farrowing crate for piglet survival lies in the physical protection from crushing that it can provide by restricting the movement and rate of posture change of the sow, allowing piglets more time to escape when the sow lies down or rolls over. Where loose farrowing pens are used, the incorporation of piglet protection features, such as sloped walls to assist controlled lying by the sow and facilitate piglet escape, are therefore critical features for success. The design of new farrowing systems, and adjustments to existing systems, should consider options that build on understanding pig behaviour in order to optimise both sow and piglet welfare (see review of Baxter et al., 2011b ).

How to reduce piglet mortality?

Early research to reduce piglet mortality was centred almost entirely around alterations to the farrowing environment. Increased control over the macro- and micro-climate of the birth site and nest area (e.g., Morrison et al., 1983) and, of course, the introduction of the farrowing crate ( Robertson et al., 1966) are some examples of tools put in place to improve piglet survival. Whilst the farrowing crate has given significant benefits for piglet survival ( Edwards and Fraser, 1997 ), it imposes physical restrictions that impact on sow welfare, preventing the fulfilment of important species-specific behaviours such as nest-building (see Baxter et al., Chapter 2: Sow welfare in the farrowing crate and alternatives, for a full discussion of the role of housing in the determination of good maternal behaviour which will benefit piglet survival).

When do sows need drip cooling?

Ensuring the comfort of the sow, which may require drip cooling during the summer months

How long does it take for a pig to become anorectic?

As the sow begins parturition, she will become partially or completely anorectic for several hours before and after parturition. Respiratory rate will increase 30 to 80 minutes before parturition to 95 to 105 breaths per minute (normal 13 to 18 per minute) and rectal temperature has been observed to increase from 38.7° to 40.0° C 24 hours before farrowing. Pigs are usually born at 15-minute intervals. Intervention is recommended if the farrowing interval is longer than 1 hour between pigs. The most common cause of dystocia is uterine inertia; however, sows should be manually examined using a hygienic technique before any treatments are administered. Oxytocin can be administered at a dose of 5 to 10 IU every 2 to 4 hours to control uterine inertia after it is established that a piglet is not lodged in the birth canal. Larger doses of oxytocin can inhibit the desired effect.

What are some examples of farrowing pens?

Did the farrowing house have easy years?

The early years of the farrowing house weren’t easy, he says. “We had pasture-bred sows, and I can still see Dad every day udder-checking sows, trying to figure out which ones need to go in the farrowing house. He spent many evenings in the farrowing house by himself.”

When did sows start cooling?

The first attempt at cooling sows was installing air conditioning and directed air down to the sows’ noses for their comfort. In the early 1970s , they installed evaporative coolers. “That was the ticket. That keeps sows comfortable,” says Steve.

What is a furrow in agriculture?

Description. In agriculture, a furrow is a trench or groove made on the soil surface by a hoe, a beast of burden-pulled plow, or a tractor, wherein seeds are sown and fertilizer is placed before its furrow is closed up. Sowing on a furrow also manages non-wetting sandy or waxy soils by allowing seeds to be placed deeper into …

What crops can be irrigated with a furrow?

Furrow irrigation is also ideal for crops prone to damage when water covers their stems or crowns, such as tomatoes, root vegetables, potatoes, and beans. It’s also utilized when growing fruit tree and vine crops like grapes or citrus. For such, a furrow is dug alongside the trees or vines in early planting stages to hold and improve water spread. Other crops suited for furrow irrigation are maize (corn), oilseeds such as sunflower, sugarcane, rice, wheat, and soybeans. Crops grown through furrow irrigation are more tolerant to excessive watering than those irrigated on flat land due to improved re-aeration of the soil after the furrow is drained. However, watering duration needs to be 12 hours or less for most crops, as water-logging also occurs even on sloped land. Long duration watering also lowers yields for legumes like beans significantly, and may worsen soil erosion, according to the NSW Agriculture Department.

How to prevent wind erosion?

According to the University of Nebraska, when planting wheat during the winter furrows provide a rough soil surface which helps stop wind erosion. Wheat drilled in furrows is also protected against winterkill. Also, using hoes means the wheat seed is planted in mulched soils that are a byproduct of stubble from the mulching of the remnants from formerly harvested crops’ residues, and as such makes for more effective tillage practices. This preserves the maximum amount of crop residue, and anchors plants well enough in the soil to prevent wind soil erosion. In addition to hoes, furrow drills with large discs can also be used to plant in mulched soils.

Can you fertilize soybeans in a furrow?

There are, however, certain seeds that are susceptible to damage when sowed with fertilizer on a furrow. According to Nutrient Stewardship, oilseeds like soybeans are damaged by in-furrow fertilization, unlike maize seeds, which have higher nitrogen requirements and tolerance against burning from fertilizer application.

What is a furrow gradient?

Furrow Gradient in Land Surface. A furrow also drains surface water in soils that have an impermeable top layer of soil caused by over-tiling practice and/or excess rains. Uniformly flat or gently sloped lands are the most suited for furrow irrigation, as in these drainage effectively occurs after excess irrigation or rainfall …

Why are my piglets not delivering?

Failure to deliver the piglets can be due to the following: A large litter and inertia of the womb. Very large piglets and a small pelvis. Two or more pigs presented in the birth canal at the same time. Illness of the sow, for example acute mastitis. Rotation of the womb. Failure of the cervix to relax and open.

Where do piglets end up in the womb?

The neck of the cervix opens into the two long horns of the womb that contain the piglets. (Fig.8-10). The umbilical cord of the piglet terminates at the placenta which is attached to the surface of the womb.
