When it comes to pigs, I believe everyone is very familiar with it, because we do not all know how to eat pork, and many people raise some pigs in our life, which is one of the more common poultry. Breeding boars are actually boars used to mate with sows, so do you know how to feed breeding boars? Let's get to know it with the editor.

Feeding and management techniques of breeding boars

Breeding boars should live in a clean, dry, fresh and comfortable environment, raise in a single circle, feed special materials for breeding boars, feed 2-3 times a day, feed 2.3-3.0 kg a day, and maintain a body condition that is not fat or thin. In addition, the following work should be done:

1. Establish a good living system. Feeding, semen collection or mating, exercise, brushing and other operations should be carried out in a general fixed time, the use of conditioned reflection to form a regular life system, easy to manage and operate.

2. Strengthen the movement of breeding boars. In addition to bad weather, it is best to exercise every day, once in the morning and once in the afternoon, 1.5 hours each time, with a journey of 2 kilometers.

3. Brush and trim hooves. Regular brushing every day, hot days combined with shower washing, can keep the skin clean, reduce skin diseases and external parasitic diseases; combined with training brushing, make boars docile and easy to collect semen. Special attention should be paid to protecting the health of limbs and hooves.

4. check the quality of semen regularly. The implementation of artificial insemination, every time to check the quality of semen, the use of this, also need to be checked once or twice a month, inferior semen boars can not be bred.

5. Prevent boars from biting the frame, and do a good job in preventing heat and cold.

6. it is better to collect semen (breeding) when boars are 8 ~ 9 months old and their body weight is up to 100 kg. The semen collection frequency is suitable for young pigs once a week and adult pigs twice a week.

Selection of breeding boar

1. Variety characteristics

Different breeds have different breed characteristics, the selection of breeding boars must first have typical breed characteristics, such as coat color, ear shape, head shape, body appearance and so on, which must meet the breeding requirements of this breed, especially the selection of purebred boars.

2. Body structure

The overall structure of the breeding boar should be symmetrical, and the head and neck, forequarters, middle and hindquarters combine naturally and well, and the eyes have a very strong feeling. The head is large and wide, the neck is short and thick, the eyes are bright, the chest is wide and deep, the back is straight, the waist is long, the abdomen is moderate, the buttocks are wide and large, the tail root is thick, the tail tip is curly, swaying freely but not drooping, the limbs are strong, the posture is correct, the hooves and toes are stout, symmetrical, and have no lame feet.

3. Sexual characteristics

Breeding boars require good testicular development, symmetry, clear outline, no monorchidism, cryptorchidism, Hernia, and no obvious prepuce urination. The sexual function is exuberant, the sexual behavior is normal, the semen quality is good. The distribution of the abdominal bottom line is clear, the milk is neatly arranged and well developed, there are no inverted nipples and accessory nipples, and there are more than 6-7 pairs.

How to train breeding boars

1. Observe and learn. First of all, let the boar to be trained to watch the climbing and semen collection process of the boar, so that it has a sensory understanding of this process. Collect estrus sow urine, boar semen and urine before training every day and spray them on fake Taiwan animals. During the training, the estrus sows are driven into the enclosure next to the classroom, so that the breeding boars can smell the sows, hear their voices, and induce the breeding boars to climb across the fake Taiwan livestock.

2. Imitate practice. After going through a period of observation and study (2-3 days), the boar should be formally trained to climb across the fake Taiwan animal. Spray estrus sow urine or boar semen on fake Taiwan animals before training. The fake Taiwan animals are placed near the corner of the wall, which is about 45 degrees from the wall, and then guide the boar to climb up.

3. Repetition is stereotyped. After the success of the first training of breeding boars, the boars were trained again every 1-2 days according to the method of initial training, in order to deepen their understanding of fake Taiwan animals. After a week or so of training, breeding boars will form a fixed conditioned reflex.

Points for attention in training of breeding boars

1. In the process of training breeding boars, trainers must not whip breeding boars, try their best to create a harmonious environment for breeding boars to collect semen, and reduce the adverse stimulation to breeding boars. Training should be carried out 1 hour after or before eating, which is helpful to keep the brain of boars awake.

2. Pig artificial semen collection should have a fixed sperm collection room, the area of which is generally about 9 inches, the site should be clean, hygienic and quiet, and the sperm collection room and fake Taiwan animals should be thoroughly cleaned and disinfected after semen collection is finished every day.

3, semen collection room floor to avoid smooth, can be covered with carpet or rubber made of square floor, as far as possible to keep dry, to avoid slipping pigs due to wet and smooth.

4. The trainers should be careful, patient and persistent, and should not be eager for success. In the process of training, they should protect the boar's reproductive organs from damage. Before artificial semen collection, we should pay attention to check the front hair of boar foreskin, if it is longer, cut it short with scissors, to prevent the boar from grabbing the foreskin hair carelessly in the process of semen collection.

The above is a summary of the breeding methods of boars for you. I hope it will be helpful to you. In fact, not only breeding boars is very important, but also buying and selecting boars is also very important. So when you buy, you must pay attention to the selection.
