Pittland pigs are native to the Brabant province of Belgium. They are backcrossed by French Bayesian hybrid pigs and British Buckley pigs, and then crossbred with Great Britain white pigs. The main features are high lean meat ratio, full rear drive and shoulder muscles, and it is the world's highest lean pig breed.
The appearance characteristics of Pittland pigs
Pitlane is gray and white, with black and white spots, and some with red hair. The head is delicate, face straight, mouth is large and straight, ears slightly forward, body width is short, cylindrical, body length 1.5 to 1.6 meters, abdomen parallel to the back, back width, full shoulder before and after, hind muscles special Developed, it is double-muscle-hip and has the reputation of "bodybuilder". The limbs are thick, but because of their muscularity, they often bear the limbs and cause injuries.
Pittland pig production performance
The sows were estrus at 7 months of age, and they were able to start breeding when their weight reached 90 kg at 8 months of age. The number of litters was about 10. Under better feeding conditions, the Pietrain pigs grow rapidly and can reach 90 to 100 kg at 6 months of age. The daily weight gain is about 750 grams. Each kilogram of weight consumption consumes 2.5 to 2.6 kilograms of compound feed. The slaughter rate is about 76%. The lean meat rate can be as high as 70% or more. The area of ​​the eye muscle is mostly above 40cm2, and the proportion of hind legs is more than 33%. Cockroaches are very thin, the incidence of poor meat (PSE meat) is high, and they have a high degree of stress sensitivity. Pittland pigs have a particularly high lean percentage and are mainly used for the production of commercial pigs in foreign countries. They are used as hybrids between male parents and anti-stress varieties to produce commercial pigs.
Once the boar reaches sexual maturity, it has a strong sexual desire. Sediment training usually succeeds once. The amount of ejaculate is 250 to 300 milliliters, and the number of spermatozoa reaches 300 million per milliliter. Sow motherhood is no less than China's local breeds, the piglet breeding rate is 92% -98%. The sow's estrus period is generally 190 days and the estrus cycle is 18 to 21 days. The number of pupas per birth is about 10, and the number of live quails is about 9.
The advantages and disadvantages of Pietrain
The Belgian Pietrain genotype CT type is less sensitive to stress, but intense stimuli can still cause stress.
Pilates' first-term sows are more prone to dystocia (rare in sows), due to the full muscles of the hindquarters and the incomplete opening of the birth canal.
Pitlan has heavy fore and hind limbs, thin limbs, and does not like exercise, and is prone to leg problems. Exercise should be strengthened to ensure that each pig is more than 1 hour per day, especially pigs in the middle and late stages of fattening. In addition, the stocking density cannot be too great. Conditional breeding can be carried out outside or grassland. The parts that are worn out when lying down should be promptly treated.
