The homeland of this breed of pigs is Denmark. Selective selection, conducted in the early twentieth century by Danish pigs by crossing local pigs with representatives of the English large white breed with protein-fortified feed, gave an excellent result. In fact, landrace is the first breed, the productive qualities of which are aimed at obtaining predominantly meat. The Landrace breed is characterized by a low content of fat in the carcass.
When comparing carcasses of landrace with carcasses of the same English white or other breed, the content of lean meat is always 3-5% higher. From the very beginning, landrace was very advantageous in its morphophysiological characteristics from other breeds of swine common at that time in Europe. For example, the amount of fat at the age of 6 months is 10%, and at the age of 9 months it is 7% less than in the large English white breed. At the same time, the percentage of protein at the age of 6 and 9 months is more by 21% and by 27%, respectively. The uniqueness of landrace is that when crossing with other breeds in the offspring, the amount of fat decreases by approximately 2-3% in comparison with the parental form.
The trunk of the pigs of the Landrace breed is long, spindle-shaped. The representatives of the breed have a rather narrow and not strongly developed thorax. In females, it averages 167 centimeters, and in males it is 182 centimeters. Legs of hogs are flat and wide, ears large, hang over eyes, skin is thin, white. The weight of males reaches 310 kilograms, and females have 253 kilograms. The thickness of the bacon at Landrace is no more than 20 millimeters. The weight per one centner of the pigs of the landrace is collected during the 189 first days of life, with an average daily gain of 707 grams.
Breeding pigs of Landrace breed is not simple and time consuming. The thing is that the youngsters of Landrace are very sensitive to the conditions of their detention. Even small deviations from the norm lead to a decrease in productivity. Especially capricious pigs of landrace breeds to quality of a forage. In the foreship, grains and green fodder must necessarily be present. For landrace, the optimal composition is considered to be food containing bone and fish flour, silage, mixed fodder. Very good for daily weight gain is affected by the inclusion in the diet of dairy products (this can be whey or skim milk). It is recommended to feed animals strictly on schedule, 2 times a day (12 hours interval).
Sowing of Landrace has good performance indicators. Typically, the pig has up to 13 piglets in the offspring. However, young Landrace is quite capricious in nursing. Small piglets must be put to the nipples of the sow not later than 45 minutes, in order that they would drink colostrum. This procedure should be carried out not only to ensure that the piglets receive the necessary nutrients and thus improve their vitality, but this is also necessary for the sow, because as a result of the suckling of the baby’s milk, painful contractions are alleviated. It is recommended to separate the babies from the sow, because because of the large weight, the mother may inadvertently pinch the babies. In addition, in some cases, the female can become overly aggressive, and cases of eating offspring are not uncommon.
Landrace is the best breed for obtaining high quality bacon. In addition, pig breeders note the early maturity of the breed, its high reproducibility, a good daily weight gain, and also the lively, flexible nature of the individuals.
The shortcomings include a weak constitution of the body, a greater susceptibility to stress and high demands on the composition of the feed.
