Low protein diet for piglets

Philippe SERENE

There is a pre-conceptualised idea that the higher is the protein content of a feed the faster the animal will grow, especially for piglets. Such rationale leads farmers to select higher protein to boost their animal growth. But actually, high protein content can create some damages as well.

An immature enzymatic system

Before weaning, the piglet is easily able to digest the high protein level of the sow milk, but after weaning, moving to a solid and vegetable based diet, it will face a more difficult challenge. The weaned piglet before 6-7 weeks of age has an immature enzymatic system: Lipolytic and proteolytic enzymes synthesis has not reached full efficiency and plant protein will be allergenic and poorly digestible.

Consequently, the crude protein will be incompletely digested and this indigestible fraction entering the hindgut will cause proteolytic fermentations and pathogenic bacteria development resulting in diarrhoea, growth retardation and even mortality.

Less diarrhoea with lower protein content diets

In many countries where the antibiotics are still used as growth promoter, the fermentation triggered by the non-digested protein will be controlled by the antibiotics. But when we are reducing the use of antibiotics or when resistance appears, diarrhoea will occur. This diarrhoea is not always associated with bacterial contamination as we often believe but the results of the fermentation of the non-digested portion of protein.

This has been one of the first major challenges that producers had to solve in Europe when antibiotics have been forbidden at growth promoter oncentrations.

Without the use of antibiotics, farmers had to reduce the protein level in piglet diets in order to avoid releasing non-digested protein into the gut.

Minimum protein requirements for weaned piglets feed

Surprisingly, it showed that such adaptation did not affect weight gain, feed intake and feed efficiency of the animals. Many studies, and a long practice of feeding in Europe, showed that reduction of protein content in feed has been beneficial to the industry by reducing the digestive disorders and prepare better the piglets for a high daily growth and a better feed efficiency.

This shows that the high levels of protein that we supply to piglets in Asia are actually not well converted by the animals. It would be better to provide lower protein content provided that we can guarantee high level of digestibility.

To define the optimal level of protein in the feed, we must look at Lysine first. As far as energy is not limiting in the diet, lysine is the first limiting amino acids for the piglet growth, the response to growth is proportional to the lysine intake.

Increasing lysine with high digestibility (around 87% from protein sources and 100% from synthetic lysine) will directly improve the daily weight gain without any adverse effect on health.

The other amino acid should be supplied with the correct ratio to Lysine to avoid any excess that would then be fermented and cause diarrhoeas. This ideal amino acid profile is now well known and the requirements for methionine, threonine, tryptophan and even valine, can be easily fulfilled.

The ideal amino acid profile in 10 to 20 kg piglets (Chung et Baker,1992)

So, in the minds of most nutritionists and veterinarians, cutting back on crude protein is a sure way to control diarrhea, even when antibiotics are used. But, that’s not true in several places around the globe. Let’s talk about Asia, China in particular. There, and despite the fact that nutritionists and veterinarians recognize the need to reduce crude protein, such measure is virtually impossible for marketing purposes and sometimes even regulatory purposes.

A low-crude protein feed is considered inferior even though assurances are provided that amino acids are there — so as to protect animal growth. I believe this is a matter of customer education. The same but different is true for the U.S. market that has started the uphill battle against growth-promoting antibiotics. There, nutritionists do not support a piglet diet with only 18 percent crude protein when their existing products contain as much as 24 percent crude protein. Clearly this is a matter of scientific development, and I know they are working hard to this end.

But, let’s consider the existing situation: two large pig markets — the U.S. and Asia — that cannot accept, yet, lower-crude protein diets for piglets (with or

without antibiotics). Is there anything that can be done to ensure that piglets don’t scour and continue to grow when high-protein diets are fed without antibiotics (U.S.) or when antibiotics are facing resistance (Asia)?

It must start with the selection of the protein sources with a specific focus on digesbility. It is not only a question of cost. We must leave as little as possible undigested protein in the gut even at a superior cost.

* From animal by products: Milk, Whey protein concentrate, Fish meal, plasma protein…

* From plants: Protein concentrate, Extruded SBM, potato protein…

We must pay an attention as well not to antagonise the digestive process. Protein sources have a high Acid Binding Capacity (ABC), limiting the natural acidification of the stomach. The natural pH evolution of the stomach moves from 4.5 at weaning to 2.8 during the growing phase. To counterbalance the negative effect that protein will have on the pH, it is advised to choose a high level of strong acidifiers (upto 8-10kg per ton), with a high negative ABC (formic and fumaric acids) and to limit incorporation of other elements that could increase feed ABC value due to their buffering activity.

* Limit calcium carbonate (use Ca Formiate)

* Reduce the dosage of Zinc Oxide from 3000ppm to 300ppm by using potentiated form

Another tools to limit the fermentation of non-digested protein will be to incorporate in the feed a portion of micronized fermentable fibers. The gut bacteria will preferentially target the fermentable micronised fiber source vs. the protein thereby limiting the negative effects of the higher protein.   So where feed producers do need to market high protein diets, use of the micronized fermentable fibers is a key formulation strategy to limit diarrhoea in piglets.

Reducing protein and energy rates in feed while maintaining broiler zootechnical performance: Case study of Nor-Spice AB® supplemented feed

By Amine Bernabia and Sebastien Tessier

The genetic improvements in broilers achieved in recent decades has allowed for significant increases in zootechnical performance and improved productivity (Hocking 2014). However, the expression of this genetic potential depends on optimal feeding and livestock condition. Determination of the required amount of energy and protein in feed is probably the most important decision to be made when it comes to feed formulation for broiler producers. Providing a well-balanced feed in order to meet the needs of broilers in terms of protein and energy while reducing feed cost is a real challenge. Furthermore, broiler producers, in order to meet sustainable agriculture standards have to optimize the use of resources in feed formulations and reduce the use of antibiotics as growth promoters. Energy and protein comprise more than 70% of the total cost of feed. The challenge facing broiler producers is how to optimize feeding costs and maintain performance in order to be competitive.

Nor-Spice AB® is a citrus concentrate containing a set of well characterized phytochemical compounds: citroflavonoids, pectic oligosaccharides (POS), organic acids, limonene and citrus essential oil. Several trials demonstrated that feed supplemented with Nor-Spice AB® contributes to improved zootechnical parameters over breeder feed recommendations.

Variability of raw materials, their cost and/or scarcity can lead to the formulation of unbalanced feed. As a consequence, broilers fed may have difficulty expressing their full genetic potential. This trial investigated the effect of Nor-Spice AB® supplementation in a “low-cost” feed reduced in protein and energy – the most expensive inputs. Here, the aim of this study was to answer the question whether it is possible to reduce protein and energy and still achieve optimal zootechnical performance by supplementing feed with Nor-Spice AB®.

EGGS INSIDE AND OUT: twist on turning

By Ron Meijerhof, Technical service manager for Hubaard ISA and Hybro

Turning of the eggs is a very critical item during incubation. Failing to turn in the first week of incubation will result in poor hatchability and poor chick quality. Turning is essential for the formation of the extra-embryonic membranes and for the orientation and position of the embryo, and with that, development and growth. Without proper turning, the embryo will not be able to take up essential nutrition from the egg. This often shows in developmental problems later on. As the embryo is not able to take up sufficient nutrients, it sometimes will die at a later stage, when the need of turning is by itself not there anymore.

Most modern setters turn once every hour continuously throughout the complete period in the setters. In older days when turning was done by hand, a frequency of turning every 4 hours was often applied. Although more frequent turning proved to be beneficial, this low frequency of turning worked by itself quite well.

Research has shown that there is a slight benefit of turning more frequently than once an hour, especially in the first days of the incubation process. The reason for this benefit is not totally clear, but could well have to do with the distribution of air and heat. More frequent turning will allow the eggs to warm up more uniformly, as the direction of the air on the trolleys will be changed more frequently.

After this initial warming period, turning once an hour seems to be sufficient for optimal results, but it is quite important to turn the eggs over on a steep enough angle. Turning the eggs to both sides over an angle of 45 degrees is optimal. However, a steep turning angle limits the air flow over the eggs, as the trays will be more close together in a turned positon. Because air flow is important for heat transfer, limited air flow will result in more overheated eggs, which will have a negative influence on incubation results.

Although turning is important at the start of incubation, it is not necessary to turn for the complete 18 days. After day 13-14, there is no problem in stopping the turning and putting the trays in a horizontal position. The benefit is that in some machines it will increase the air flow over the eggs, and with it the heat transfer. In this way we can better remove the heat from the eggs and prevent overheating. When turning is stopped, the trays should be placed in a horizontal position. Leaving them in a turned position will result in local overheating because air distribution will not be uniform.

The reason most incubators do not turn to both sides over the whole 45-degree angle is to not only prevent limiting the air flow, but also to allow bigger eggs to be placed in the trays without crushing them with the upper tray. Although 45-degree turning angles are preferable, the negative effect of turning on a lesser angle is limited as long as the angle is 38 degrees or more. Turning at angles below 38 degrees will influence the results negatively. Turning should be to both sides over 38 degrees or more, and turning over one side to 45 degrees and the other side to 31 degrees will not work as well as turning both sides over 38 degrees.

Although turning angles in most machines are taken for granted, it is a good practice to once in a while check if the turning angles are still up to standard. Sometimes we see after a number of years that trolleys or machines are not turning that easily anymore, resulting in a too-low turning angle, or below the minimum required level.

Failing to turn, not turning frequently enough or not turning over a large enough angle can result in serious problems. It can result in both early and late mortality, and will show in malformations, small embryos, malpositions etc. However, a first indication of problems that can be related to turning is the number of embryos with the head under the left wing. The normal position of an embryo at the end of the incubation process is with its head under the right wing. When the head is not under the wing but on top of the right wing, this is a typical sign of overheating. But when the head is under the left wing instead of the right wing, it might be that we are dealing with a system where the turning angle is not steep enough. When we see more of these malpositions occurring during break out procedures, a check on the turning angle of the trolleys might be necessary.

With the goal of making a good location even better, PAS Export & Silos will build a new 4,000-tonne transit warehouse in Ayutthaya to improve logistic efficiency as it targets 15% sustained growth per annum.

Raw materials can be delivered to the plant via ship, truck and train, said Krit Pornamnuaysub, managing director. Whole soybeans can be shipped to Laem Chabang and then transferred to smaller boats that are towed to its warehouse in Ayutthaya or they can be trucked directly from Laem Chabang. However, transitioning cargoes from Laem Chabang and shipping them via barges on the Chaophraya River to Ayutthaya is more cost effective.

The new transit warehouse being built in Ayutthaya in Q3 this year will reduce both time spent on empty backhauls and overall travel distance. As a result, the average delivery cost for shipping products to customers in the upper north will be less than 0.30 baht/kg. In comparison, he estimates that it costs his competitors around 0.55-0.70 baht/kg to cover the same route. Continue reading
