Description

Technical Field

[0001] The invention relates to a feeding method, in particular to a feeding method for fattening pigs in a large pig house, and belongs to the technical field of fattening pigs. Background Art

[0002] Pig houses are buildings for raising pigs. According to different purposes of raising pigs, they can be divided into breeding houses, gestation houses, farrowing houses, finishing houses, and fattening houses. Feeding and drinking water are generally carried out in the houses. There is a playground or feces passage for pigs outside the houses. The houses are separated by partitions or fences. Group feeding is generally adopted for raising and fattening pigs. It can not only make full use of the pig houses and equipment, save energy, improve labor efficiency, and reduce pig production costs, but also take advantage of the fact that pigs compete for food in the same trough, increase the appetite of pigs, and increase daily weight gain; A Chinese patent publication (CN201410325084.6) discloses a method for feeding pigs in a microbial fermentation bed large-pen pig house, which can stabilize the health of the feeding pigs, thereby ensuring the quality and efficiency of fattening pig farming. However, in the existing pig fattening process, the feed fed in each feeding cycle is fixed, and there is a lack of measures to optimize the feed according to the feeding effect of pigs with different weights and physiques, resulting in the inability of some pigs to maintain rapid weight growth when they gain weight to a certain stage; In order to solve the above technical problems, a method for feeding fattening pigs in a large pig house is proposed. Summary of the invention

[0003] In view of this, the present invention provides a method for feeding fattening pigs in a large pig house in separate pens, so as to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0004] The technical solution of the present invention is achieved as follows: a method for feeding fattening pigs in a large pig house by pens, comprising the following steps: S1. Divide the pig house into pens, divide the pig house into multiple areas and separate each area; S2. Disinfection and cleaning of pig houses: clean and disinfect the pig houses after separation, adjust the temperature inside the pig houses, and ventilate and remove dust; S3. Classify the pigs, make preliminary divisions of the pigs according to their weight, and classify special pigs separately; S4, introduce the pigs into the pig house after classification, so as to separate the different types of pigs; S5. Formulate feeding cycle and make preliminary formulation of feeding cycle according to pig herd type; S6, periodic feeding, feeding the pigs regularly to complete a feeding cycle; S7. Count the feeding effects of various pig groups; S8, re-dividing the pens, re-dividing the pigs that have completed a feeding cycle, and adjusting the size of the pen area according to the number of pigs; S9, weigh the pigs, weigh the pigs that have gone through a feeding cycle, and combine the pigs that meet the standards; S10, lead out the pigs, and lead out the pigs after fattening all the pigs.

[0005] Further preferably, in said S1, when the pig house is divided into pens, the proportion of pigs of different weights can be estimated according to the general condition of the pigs, and the area of ​​each pen of the pig house can be adjusted according to the estimated result.

[0006] Further preferably, in S2, pig house cleaning and disinfection should be carried out regularly, and the pig houses need to be cleaned and disinfected separately before and after re-dividing the pens.

[0007] Further preferably, in said S3, when classifying the pigs, weight is used as the overall standard, and pigs with weak competitiveness, weak physique, and difficulty in gaining weight are separated into separate pens. When separating the pigs, the pigs are classified based on similar weight. If the weight difference is too large, the abnormal individuals are separated into separate pens.

[0008] Further preferably, in S4, after the pigs are introduced, they need to adapt for a certain period of time, and during the adaptation period, the pens are adjusted according to the status of the pigs.

[0009] Further preferably, in S5, the feeding cycle durations of different pig groups are different, and the feeding intervals are different, and the difference in feeding cycle durations does not exceed fifteen days. The feeds of different pig groups should be adaptively adjusted according to the physical constitution of the pig groups.

[0010] Further preferably, in said S8, when re-dividing the pens, if the weight of a special group of pigs reaches the standard, a certain period of adaptive observation is required when merging with other groups of pigs. After re-dividing the pens, the feed is adjusted accordingly according to the feeding effect of the pigs, and the feed is redistributed to the feeding objects according to the effective feed of different weights.

[0011] Further preferably, in S9, if the number of pigs meeting the standards is large, some of the fences are removed to expand the range of pig activity.

[0012] Further preferably, in S10, after the pigs are led out, they are cleaned, the pig house is cleaned and disinfected, and the pig house pens are reset to facilitate fattening of the next batch of pigs.

[0013] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution: 1. The present invention formulates feeding cycles for different pig groups, observes the weight gain effect of feed within a single feeding cycle, and distinguishes the weight gain effects according to the characteristics of different pig groups. After completing a feeding cycle and re-dividing the pig groups, the feed is optimized and adjusted according to the pig groups with different weights, and the feed is redistributed according to the weight gain effect of different pig groups, thereby ensuring the weight gain efficiency of the pig group and preventing the pig group from being unable to continue to gain weight rapidly after feeding to a certain stage; 2. The present invention ensures that the pigs have sufficient space to move around at all stages of weight gain by adjusting the size of the pig house partition area in real time, thereby facilitating ventilation and disinfection of the pig house and reducing the disease infection rate of the pigs.

[0017] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0018] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 As shown, an embodiment of the present invention provides a method for feeding fattening pigs in a large pig house, comprising the following steps: S1. Divide the pig house into pens, divide the pig house into multiple areas and separate each area; S2. Disinfection and cleaning of pig houses: clean and disinfect the pig houses after separation, adjust the temperature inside the pig houses, and ventilate and remove dust; S3. Classify the pigs, make preliminary divisions of the pigs according to their weight, and classify special pigs separately; S4, introduce the pigs into the pig house after classification, so as to separate the different types of pigs; S5. Formulate feeding cycle and make preliminary formulation of feeding cycle according to pig herd type; S6, periodic feeding, feeding the pigs regularly to complete a feeding cycle; S7. Count the feeding effects of various pig groups; S8, re-dividing the pens, re-dividing the pigs that have completed a feeding cycle, and adjusting the size of the pen area according to the number of pigs; S9, weigh the pigs, weigh the pigs that have gone through a feeding cycle, and combine the pigs that meet the standards; S10, lead out the pigs, and lead out the pigs after fattening all the pigs.

[0020] In one embodiment, in S1, when the pig house is divided into pens, the proportion of pigs of different weights can be estimated according to the approximate status of the pigs, and the area of ​​each pen of the pig house can be adjusted according to the estimated results. The thermal insulation performance of the roof and wall enclosure structure of the pig house is strengthened to facilitate the growth of the pigs. Slag or brick cushion layers are added to reduce the heat dissipation of pig body temperature through the cement floor, or overhead prefabricated reinforced concrete floors are used. The pig pens are made of corrosion-resistant steel pipe pig pens or wooden or bamboo pig pens.

[0021] In one embodiment, in S2, pig house cleaning and disinfection should be carried out regularly. The pig houses need to be cleaned and disinfected separately before and after re-dividing the pens. The environmental hygiene of the pig houses should be ensured during feeding, and feces and debris should be removed every day. The pens and their surroundings should be disinfected regularly, and safe and effective disinfectants should be selected to avoid stress on the pigs or poor disinfection effects. Pay attention to checking the health status of the pigs so as to detect diseases as early as possible and avoid large-scale outbreaks of diseases.

[0022] In one embodiment, in S3, when classifying the pigs, weight is used as the overall standard, and pigs with weak competitiveness, weak physique, and difficulty in gaining weight are separated into separate pens. When separating the pigs, they are classified based on similar weight. If the weight difference is too large, the abnormal individuals are separated into separate pens. After the pigs are separated, they are educated in time according to their living habits, and a stable group living order is established as soon as possible. The habit of eating, defecating, and sleeping in a fixed place should be cultivated. The choice of a fixed place should take into account the habits of the pigs and whether it is convenient to manage. The trough should be placed in a dry place away from drinking water. At the same time, it should be considered whether it is convenient for the breeder to feed.

[0023] In one embodiment, in S4, after the introduction of the pig herd, a certain period of adaptation is required, and the pens are adjusted according to the status of the pig herd during the adaptation period. Before the introduction of the pig herd, the piglets need to be screened. The selection of piglets is an important part of fattening pig breeding. Piglets with excellent breeds, good development, strong physique and consistent growth should be selected to ensure that the piglets are fattened quickly and the feed utilization rate is good.

[0024] In one embodiment, in S5, the feeding cycle durations of different pig groups are different, and the feeding intervals are different, and the difference in feeding cycle durations does not exceed fifteen days. The feeds of different pig groups should be adaptively adjusted according to the physical constitution of the pig groups.

[0025] In one embodiment, in S8, when re-dividing the pens, if the weight of a special group of pigs meets the standard, a certain period of adaptive observation is required when merging with other groups of pigs. After re-dividing the pens, the feed is adjusted accordingly according to the feeding effect of the pigs, and the feed is redistributed to the feeding objects according to the effective feed of different weights.

[0026] In one embodiment, in S9, if the number of pigs meeting the standards is large, some of the fences are removed to expand the range of pig activities.

[0027] In one embodiment, in S10, after the pigs are led out, they are cleaned, the pig house is cleaned and disinfected, and the pig house is reset to facilitate fattening of the next batch of pigs.

[0028] When the present invention is working: the weight proportion of the pig group is estimated, the pig house is preliminarily divided into pens according to the estimated result, the pig house is disinfected and cleaned after the division, the pig group is classified and introduced into the pig house, and pig groups with different characteristics are allocated to different pens, a feeding cycle is formulated according to the weight and physique of the pig group, and a feeding observation of a feeding cycle is carried out, a feeding plan is re-formulated according to the feeding effect, and the pig group that has passed a feeding cycle is re-divided into pens, according to the weight gain effect of the feed obtained in a single feeding cycle, and the weight gain effect of the feed on pig groups with different characteristics, after completing a feeding cycle and re-dividing the pig group, the feed is optimized and adjusted according to the pig groups with different weights, and the feed is redistributed according to the weight gain effect on different pig groups. If most of the pig groups meet the weight standard during the feeding process, some partitions are removed to expand the activity range of the pig group. After the feeding is completed, the pig group is led out and the pig house is reset and cleaned and disinfected.

[0029] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
