Will increasing the growth rate of Pigs reduce variation?

Increasing the growth rate of all of the pigs in a population will not reduce variation but it will result in more of the lighter weight pigs reaching the minimum weight required by the market before the building needs to be emptied. In addition, restricting access to feed or water can reduce the growth rate of pigs and is also likely to increase variation within the population. Ensuring that there are sufficient drinkers and feeder spaces for all of the pigs in the pen will help minimize variation.Floor Space: On commercial units, pigs are kept at floor spaces that reduce average growth rates but increase the total live weight produced from the facility. Surprisingly, studies have shown that crowding pigs has no impact on variation in weight within a populations. Managing Variation.Variation in live weight in growing pigs causes a number of problems for producers and results in significant economic loss. However, it is important to bear in mind that biological variation exists for a reason. It is the foundation of natural and artificial selection and as such is the basis for genetic improvement in performance traits.



What affects the growth of pigs?

Although numerous variables can affect the performance of a pig, slow growth is usually considered a result of interactions among the environment, nutrition, and genetic potential for lean growth of pigs in a modern confinement production system (Botermans et al., 2000; Georgsson and Svendsen, 2002; Quiniou et al., …

What is the growth rate of a pig?

With average genetics, pigs can hit a maximum growth rate of 970 g/day at 78 kg body weight, while those with improved genetics can exceed 1120 g/day at 93 kg. At higher weights, growth rate falls as the pigs get closer to maturity.

How do you increase the growth rate of a pig?

Increasing the concentration of nutrients in the diet will help improve growth rate. Feed supplements such as Purina® HIGH OCTANE® show supplements are valuable at optimizing energy, essential amino acids, and other ingredients that can influence the amount a pig eats per day.

Do pigs have rapid growth rate?

Young pigs grow very rapidly. Rate of gain declines as the pigs grow beyond 150 pounds. Daily muscle gain is similar but not identical to daily gain (Figure 2). In addition to muscle, the pig is adding size and weight to its organs, fat reserves, and bones.

Which group of pigs show the greatest growth rate?

… from birth or wean to 20 weeks of age, herds B and C had the highest growth rates, while herds G and H had the poorest.

How do you increase the number of pigs?

How do you slow down pig growth?

The growth plate may be destroyed by drilling or scraping it to stop further growth. The leg length discrepancy will gradually decrease as the opposite leg continues to grow and “catch up.” Metal staples, or a metal plate with screws, may be placed around the sides of the growth plate to slow or stop growth.

How do you reduce variation in pig growth?

Ensuring that there are sufficient drinkers and feeder spaces for all of the pigs in the pen will help minimize variation. On commercial units, pigs are kept at floor spaces that reduce average growth rates but increase the total live weight produced from the facility.

Does crowding affect pig growth and variation?

On commercial units, pigs are kept at floor spaces that reduce average growth rates but increase the total live weight produced from the facility. Surprisingly, studies have shown that crowding pigs has no impact on variation in weight within a populations. The major opportunity for managing variation is in the late finishing phase of production.

Why is variation in live weight important in growing pigs?

Variation in live weight in growing pigs causes a number of problems for producers and results in significant economic loss. However, it is important to bear in mind that biological variation exists for a reason. It is the foundation of natural and artificial selection and as such is the basis for genetic improvement in performance traits.

Why won’t my pigs grow?

At times, it is imperative to increase the pig growth rate of pigs intended for show. There are many factors that influence growth. It is important to identify these factors, and pinpoint reasons for poor performance. Poor feed intake is the primary cause for low growth rate
