HOW TO HANDLE HEAT STRESS IN PIGS.
Heat stress affects the pig industry in tropical climates as well as temperate regions. Losses due to heat stress include nonproductive days for sows and economic losses in growing-finishing pigs. Even in mild climate conditions such as the Netherlands pigs have problems in the summer with performance losses due heat stress .This problem can be dealt with by improved nutrition.
Pigs are much more sensitive to hot weather than other livestock animals – largely due to the fact that pigs hardly sweat and their lungs are relatively small compared to their body size. When pigs are exposed to heat stress, their respiration rate increases, pulse rate falls, they start panting heavily and they stop eating because this contributes to further heat production. The fact that bigger pigs are more sensitive to heat stress can be clearly seen in growth performance.
Investigation of different weight classes (75, 80 and 28 kg body weight) showed a direct negative correlation on average daily gain (ADG) with increasing room temperature. While 75 kg pigs start to decrease their ADG at around 23°C, pigs weighing 25 kg can compensate up to 27°C (Langridge, Western Australia, 2014). A commonly accepted temperature range for sows in the farrowing house typically spans between 21°C and 25°C - though this is too big of a range. Nursery sows begin to show signs of heat stress starting at 22°C . The feed intake drops almost 0.5 kg/day as temperature increases to 25°C.
Technical solutions to reduce heat stress are often time
consuming and can be highly expensive, e.g. building cooled stables. A nutritional approach can prove more adaptable and quicker to implement. Based on current knowledge there are some measures we can take to improve the swine productivity during periods of heat stress.
The nutritional intervention include; 1) Smaller, more frequent meals per day and/or night feeding.
2)A sufficient supply of fresh, clean water.
3)Wet the feed with water.
4)Use pelleted feed instead of mash.
5)Lower crude protein.
6) Replace starch with fat as an energy source.
7) Use less fiber.

BIOTECH AND PRRSV RESISTANT PIGS.
A research involving scientists have bred Pigs resistant to a PRRSV, Using CRISPR ;(CRISPR/Cas9 gene-editing method—to breed pigs resistant to infection).
Porcine reproductive and respiratory syndrome virus (PRRSV) emerged in the 1980s, and the syndrome now afflicts these hoofed animals worldwide, causing illness, death and miscarriage. It has been designated the most economically significant disease for swine, costing livestock producers in North America $600 million annually from deaths and medical treatments.
Vaccinations have mostly failed to prevent the syndrome's spread, but a new approach by biologists at the University of Missouri may mark a turning point. They are one of the first teams to develop a commercial agricultural application for the revolutionary CRISPR/Cas9 gene-editing method—to breed pigs resistant to infection.
CRISPR/Cas9 is a gene-manipulation tool that allows scientists to make changes to DNA with razor-sharp accuracy.
The tool has generated excitement in the research community because it allows rapid modification of gene function, replacing older and less efficient methods. For porcine reproductive and respiratory syndrome, Missouri's Randall Prather, Kristen Whitworth and Kevin Wells turned to the technique to breed three piglets that lacked a protein on cells that acts as a doorway for the virus. The edited piglets were grouped together in a pen with seven normal piglets, and then they all were inoculated with PRRSV.
About five days later the normal pigs grew feverish and ill, but the genetically edited pigs did not. Despite sharing close quarters with their sick pen mates, they remained in top health throughout the 35-day study period. Blood testing also revealed that the edited animals did not produce antibodies against the virus—further evidence that they evaded infection entirely. “I expected the pigs would get the virus but not get as sick,” Prather says. “But it is just night and day. The pigs are running around with the other pigs coughing on them, but they are just fine.”
This work and other recent experiments demonstrate the promise of CRISPR/Cas9 for the care of domestic animals. Late last year geneticists at the University of California, Davis, employed the new technique to breed dairy cows that do not grow horns.
The study is published in the Nature Biotechnology.

ARTIFICIAL INSEMINATION OPERATIONS IN A STUD FARM.
The work is carried out in a total of five pens on either side equipped with dummy sows. Boars are brought in from the left or the right side of the building, by the other staff members.
The collection pens are equipped with 'warming pens', where boars get themselves excited while waiting for their turn. Once the door opens, the boar will mount the dummy. For staff members it is just a relatively quick job to wait for the first – highly contaminated – ejaculate to drop on the floor, after which the semen collector is connected to the boar's penis.
For this purpose, five copies of the 'Collectis' are being used – a device by IMV Technologies, made up of an artificial vagina, which can automatically widen and loosen up in order to stimulate the boar's penis. The device also contains a filter.
At the other end of the Collectis, a plastic bag is connected, which will catch the filtrated ejaculate, avoiding human interference or bacterial contamination. Once the boar has done his business, he usually automatically retracts and lies down in a corner of the pen. Staff can then easily take the bag, seal it, scan the boar's ear tag and print a sticker with the relevant bar code. Thus the labelled semen is put into a pneumatic tube system and arrives safely in the laboratory.
The semen has to be tested whether it matches the quality requirements as set by Cobiporc. This is performed with the Ivos II, Casa, from Hamilton Thorne, which can simultaneously analyse as well as record obtained data. Elements checked include e.g. the morphology (what is the shape of the semen cells?), their motility (how do they move?) and sperm cell concentration. All production data are recorded into eSmile, specific AI centre management software, guaranteeing traceability.
Once all is approved, the computer will start a dilution programme. With Cobiporc's own extenders Kobidil+ and D-Max 6, the semen gets diluted so that one ejaculate provides enough for on average 30 bags – again sufficient for 30 artificial insemination sessions on-farm. In this way, although being completely absent, sows are on the mind of each and every individual, both porcine and human.

Breeds: Piétrain/ Duroc-Piétrain
Annual output: 530,000 doses
Filling machine.
Filling semen into bags happens with a machine called GTB 100 V3, which is supplied by French artificial insemination equipment company IMV Technologies, owner of also the Collectis and the eSmile software.
The GTB machine was developed in 2009, improved in 2010 and the third generation appeared on the market in 2014, explains Benoît Bouvier, sales director for Europe, Middle East and Africa. Only consisting of composite material, and not having sharp edges, the filling machine is easy to clean and maintain. In addition, the semen can be filled in regular bags of 80 ml, but can also be filled in smaller portions of 40 ml, destined for breeding farms using intra-uterine (deep) insemination.
