The light system of piglet breeding

First, Good health of the piglets effect on quality throughout the breeding process.

The weaning age of piglets has been raised from 8 weeks of age in the 1950s and 1960s to the current average of 22-26 days. However, early weaning also inevitably brings about a series of problems. Including piglet nutrition, feeding, health, behavior and Environmental requirements, and the result effects on sow fertility. We need to face the changing tasks of global pig farm industry. It is noteworthy recently that, especially in Europe, more and more people are beginning to pay attention to the issue of animal welfare. These issues have led to a great deal of related research, such as improving visceral health and immunity, a problem that was almost neglected in weaned piglets prior to that. As a result, people are paying more attention to and researching on the problems of intestinal diseases, animal welfare and intestinal nutrition of weaned piglets. Pig producers, feed manufacturers, scientists and engineers all try to solve these problems. And there is growing evidence that the problems that plague weaning may have far-reaching effects on the growth and reproduction of piglets and even their lifelong lives. In short, the weaning process has an unprecedented importance.

1)        Physiological characteristics of piglets

Physiological characteristics of piglets mainly manifested as imperfect digestive function, rapid growth and development, neuro-system is not perfect, low immunity, high nutritional needs, easy to get sick, high mortality, piglets from birth to weaning mortality rate as high as 20%.

2)        Weaned piglets face three challenges

a)        First, the food supply has undergone great changes. In addition to having to look for food from low feed troughs and face new food forms, piglets have never had the same composition as piglets, and piglets have had to adapt to the digestion of fat Road to the digestion of complex carbohydrate changes.

b)        Second, we must deal with changes in the physical environment. After weaning a few litters will be placed together in a nursery pigs together. Piglets that have adapted to live with sows and littermates have had to learn to live without sows and face competition from many piglets.

c)        Third, psychological stress caused by the transfer of columns and mixed columns. Although many scholars believe that stress will slow growth, its impact is unclear. Taking into account the above changes, we can easily understand why the growth rate of piglets after weaning slowed. The extent of the slowdown depends on how well the piglets adapt to the new environment and reach the new dynamic balance.

3)        Weaning piglets growth potential

Whittemore and Green (2001) suggested that in commercial farming, 21-day-old piglets weaned with no clinical disease and overt stress could achieve the goals of feeding at 1, 2, and 3 weeks after weaning Velocity of 100,200,400 g / d. In fact, the above growth rate does not represent a good result. Similarly, the authors also reported that a healthy 3-week-old piglet weighing 5 kg grew at a rate of 500 g / d during ad libitum at twice the performance of a commercial farm under Edinburgh's experimental conditions. Their research also shows that piglets grow faster when tested with modern pigs under the same experimental conditions as Hodge (1974), confirming the greater potential for growth in weanling piglets. Undoubtedly, piglets have great potential for growth, and their growth rate can reach 2-3 times the growth rate of the best commercially available pigs nowadays. The question is why this potential for growth is far from reaching and how to bring production performance closer to growth potential.

4)        The importance of weaning to post-weaning grow period.

It is predicted by the Gompertz growth function that mature, heavier pigs will grow faster at any age than mature, smaller pigs. So as the growth progresses, the difference in body weight at weaning does not persist but is magnified. The heavier pigs always grow faster than the lighter ones at any age. Campbell (1989) analyzed the weaning records from a large Australian farm and found that the difference in body weight of 1.8 kg (6.14 kg vs. 7.95 kg) at weaning of 25-29 days of age increased from 5 days to 78 days at 5 days and at 150 days When increased to 10kg. A study by Mahan and Leoin (1991) found that it takes 11-22 days more for weaning pigs weighing 4.1-5.0 kg to 105 kg slaughter weight than pigs weaning 7.3-8.6 kg. Recent studies by Wolter and Eillis (2001) also reached similar conclusions. They found differences in body weight of 1.5 kg (3.9 kg vs 5.4 kg) at weaning of 3 weeks of piglets by 8.6 kg at slaughter. In a more extensive study, Dunshea et al. (2003) found that the primary weight difference of 0.37 kg (1.86 kg vs. 1.39 kg) increased to 1.9 kg at 2 weeks of age and 13 kg by 23 weeks (107.1 vs. 94.3 kg). This shows that this stage plays a key role in future quality and output.

Second, the use of light to adjust the health of piglets

Overall, how to improve the survival rate, weight and quality of weaned piglets is a problem that pig producers, feed manufacturers, scientists and engineers all try to solve. According to this issue, the company through the growth cycle of plants and animals, in addition to the use of growth-regulating hormone, the light is also a mainstream direction. Light, as an important ecological factor in nature, has an obvious effect on animal behavior. For changes of light, the animal adjusts itself to make appropriate behavioral responses. However, the role of light in pig production has not been well understood and the management of pig farms is neglected by most pig managers and breeders.

The company through a number of years after a large number of tests and verification, reached by adjusting the pig farm day and night to control the difference between the environment, the artificial environment of a specific set, with light intensity, irradiation (heat source), color Degree, integrated together, in the whole process, consciously and actively to save energy consumption to adjust the growth process. In order to achieve the shortening of the growth cycle, material and material savings, the total value reflects the performance enhancement. Since the publication of a paper entitled "Light to animals helps to increase productivity" by Soviet scientist Yurkov, scientists and large enterprises and related research institutes around the world are experimenting with it. Our products are mainly through the sun to extract the beneficial light of pigs, through the beneficial light waves to promote their growth.

Endocrine system of pigs:

Hormones are substances secreted by various glands and are transported throughout the body by the blood or other body fluids that affect and control the metabolic processes in pigs. There are 9 important glands in the pig that control important functions of the body.

As shown below:

Growth hormone: to promote the growth of most of the body's tissues, synthesized by the combination of the pituitary gland and the hypothalamus. The hypothalamus, a region of the brain, is responsible for regulating nervousness and controlling most other glandular activities.

Each part of the pituitary gland has its own task. Pituitary gland cells secreted hormones are mainly seven kinds, they were growth hormone, prolactin, thyroid stimulating hormone, adrenocorticotropic hormone (luteinizing hormone and follicle stimulating hormone) and black cell stimulating hormone. The pituitary gland itself does not make hormones, but rather acts as a warehouse. The antidiuretic hormone and oxytocin, produced in the supraoptic nucleus and paraventricular nucleus of the hypothalamus, are delivered to the neurohypophysis through nerve fibers between the hypothalamus and the pituitary gland and released into the bloodstream when needed by the body.

The main function of pituitary hormone is as follows: Growth hormone: to promote growth and development, promote protein synthesis and bone growth.

2 the use of light Features:

1, Our product is only extracted from the sun to help piglets grow light in order to regulate the energy wave, so that the regulation of pituitary growth hormone, and strengthen their healthy growth.

2, the product emits energy waves can penetrate the skin to stimulate cell growth, to ensure its healthy growth.

3, the product design to subvert the traditional breeding mode. The traditional growth mode is to allow pigs to eat in the dark after the growth of the environment, to ensure that pigs eat enough, sleeping incense, grow fast. The company is located in:

4, the use of this product after the process of improving light to promote animal sleep.
