ABTL Seminar on Gut Health at Indian Poultry Journalists Association (IPJA), Hyderabad.

"Gut Health:A New Paradigm in Poultry Production"
 ABTL presented a technical seminar in the area of Gut Health in Poultry in the ongoing technical seminar series hosted by Indian Poultry Journalists Association (IPJA), at  Hyderabad on June 24,2017Dr. Anand in the talkexplored the area of gut health and outlined key factors that are important in the development and maintenance of optimal gut function.

Dr. Anand, presenting the seminar on gut health at IPJA, hyderabad. 
The efficient conversion of feed into its basic components for optimal nutrient absorption is vital for both broiler and broiler breeder production and welfare. Gut health, an intricate and complex area combining nutrition, microbiology, immunology and physiology, has a key role to play. When gut health is compromised, digestion and nutrient absorption are affected which, in turn, can have a detrimental effect on feed conversion leading to economic loss and a greater susceptibility to disease. In addition, recent changes in legislation on the use of antimicrobials, differing feed requirements and more efficient birds highlight the need for a better understanding of gut function and gut health.

Variation of Soybean Meal Quality Across Countries

Quite often we are asked that why soybean meal of different origin requires a distinct feed specification matrix record. In other words, why soybean meal from the U.S. needs to be a different ingredient from soybean meal from India, or Argentina, or Brazil. After all, they all start with very similar raw material, which is raw soybeans from a handful of seed genetic suppliers. And, although growing conditions are not exactly similar across the world, they still are not significantly disparate to warrant such a wide difference in soybean meal nutrient specifications. To explain this issue, we must focus on three issues that cause soybean meals from different sources to have different nutrient values:
1. Soybean hulls

Quite often, a part of the outer shell of the beans (the hull) is added back to the soybean meal. Thus, by adding more hulls back, we get from 48 percent down to 44 percent crude protein, with a corresponding increase in total fiber concentration.
2. Residual oil

The amount of oil extracted from soybeans differs according to the processing method followed, which is not exactly similar across the world. It appears the factories within a region or country tend to follow similar methods, which results in similar end product specifications.
3. Thermal processing

The solvent extraction method used for oil removal from soybeans involves a certain degree of thermal processing. This cooking can be mild or severe, depending on the processing method and quality of machinery. Exposure to high temperatures denatures the protein and renders it less digestible/available to animals. This is a major issue that greatly diminishes the value of the primary source of animal feed protein worldwide.
In brief, the resulting end nutritive value of soybean meal has nothing to do with country of origin, but rather with processing methods that tend to be similar within a country. This is why soybean meal purchases are often characterized by country of origin.
"Soybean meal is not the same ingredient everywhere as its nutritive value depends on country of origin"
Crude protein concentration has been and remains the most important aspect in quality control for soybean meal. But, soybean meal is an international commodity, and despite being used throughout the world, it is exported by a handful of countries. It pays then to focus on such major exporters to investigate whether their processing conditions affect not only protein concentration, but also protein quality, which is equally important.
In a recent study published in Poultry Science, the nutrient composition, ileal amino acid (AA) digestibility, and apparent metabolizable energy for poultry (AME) of 55 soybean meal (SBM) samples were evaluated from the United States (US; n = 16), Argentina (ARG; n = 16), Brazil (BRA; n = 10), and India (IND; n = 13). Samples were collected from commercial mills in Southeast Asia, and they were compared using laboratory analyses and animal studies.
There were significant (P < 0.05 to 0.001) differences due to origin in crude protein (CP), fat, ash, fiber and non-starch polysaccharide (NSP) contents of SBM. The average CP content of US, ARG, BRA, and IND samples was determined to be 47.3, 46.9, 48.2 and 46.4 percent (as-fed basis), respectively. Compared with SBM from other origins, crude fiber and NSP contents were lower (P < 0.05) and sucrose content was higher (P < 0.05) in the US samples. The IND samples had the highest (P < 0.05) contents of fiber, ash and NSP, and lowest (P < 0.05) contents of fat and sucrose. Differences (P < 0.0001) were also observed due to country of origin for in vitro protein quality measures (urease index, KOH protein solubility, and trypsin inhibitor activity). Significant (P < 0.001) effects due to origin were ob-served for all minerals. Soybean meal from the US and IND had higher (P < 0.05) calcium contents (0.45 percent) compared with those from ARG and BRA (0.28–0.31%). Phosphorus and potassium contents were lowest (P < 0.05) in SBM from IND, and no differences (P > 0.05) were observed in SBM from other origins. Iron content was markedly high (928 mg/kg) in SBM from IND compared with those from other origins (103–134 mg/kg).
Major origin-related differences (P < 0.0001) were observed in the AME of SBM. The average AME content of US, ARG, BRA and IND samples was 2,375, 2,227, 2,317 and 2,000 kcal/kg (as-fed basis), respectively. Total AA contents of US, ARG, BRA, and IND samples were similar (P > 0.05) for 9 of the 17 amino acids. Major differences (P < 0.05 to P < 0.001) due to origin were determined for the digestibility of all AA. The IND samples had the lowest (P < 0.05) digestibility and no differences (P > 0.05) between samples from other 3 origins. However, the digestible CP content of US SBM was higher (P < 0.05) than those of ARG and IND, but similar (P > 0.05) to that from BRA. The digestible CP contents of SBM from the US, ARG, BRA, and IND were 40.0, 38.6, 39.8, and 36.7 percent, respectively. Digestible contents of indispensable AA, in general, followed the same trend as that of digestible CP.
In conclusion, the present evaluation showed that major differences in nutritive value do exist between SBM from different origins in terms of nutrient contents, AME, and digestible AA.

The Importance of Gut Health in Consistent Breeder Performance

The Gastrointestinal (GI) Tract
A key factor in the biological performance, health, welfare and efficiency of livestock is the health of the gastrointestinal (GI) tract. Within the poultry industry there are many initiatives aiming to understand gut health and how it can be influenced to improve production and reduce disease. These initiatives have shown that there is a need for further understanding of gut physiology and the relationship between the gut microbiota and the host. Decades of research in a wide range of animal species has shown that gut health can be influenced by a wide range of intrinsic and extrinsic factors on the farm, and understanding these factors is key for improving gut health as the poultry industry actively reduces antimicrobial use.
Optimal gut tissue development is critical for correct gut function; development of the gut starts during incubation and continues once the chick hatches out of the egg. During the first week of life, the gut tissues undergo rapid development and the villi at the gut surface elongate. During the initial villi growth the villi reach approximately 50% of their final length. If villus growth is impaired during the first two weeks of life it can have long term consequences for the absorptive capacity and efficiency of the gut in the adult bird. The intestinal tract is covered by a single layer of epithelial cells held together by cell junctions; together these create a physical barrier ensuring separation of the gut contents and the internal tissues separate. This barrier prevents bacteria from the gut from entering the body proper; failure of this barrier results in a leaky gut which allows bacteria to translocate into the gut tissues and blood stream the where they can cause disease. The result can be localized issues in the gut tissues; such as in the case of necrotic enteritis where Clostridium perfringens crosses the gut barrier resulting in severe, and sometimes fatal, damage to the gut tissues. Alternatively, when the bacteria enter the bloodstream and become dispersed around the body there can be pathology found in body systems other than the gut such as the liver, the heart and the skeletal structures. Bacterial chondronecrosis with osteomyelitis (BCO) is such a condition where failure of the gut barrier allows gut bacteria to enter the blood stream and gain access to osteochondrotic microfractures in the developing cartilage. Establishment of healthy gut architecture and maintenance of the gut barrier is therefore essential to broiler breeder performance and health. In the older breeder there is a greater risk of the gut barrier failing which increases the likelihood of bacterial translocation. As such the provision of gut health products designed to promote the gut barrier can help reduce the potential of bacterial translocation.

Development and Maintenance of Optimal Intestinal Health
Optimal intestinal health is heavily reliant upon the acquisition and maintenance of a balanced intestinal microbiota, this has become one of the key topics in poultry husbandry. Bacteria reside in all known habitats, therefore it is not surprising that evolution has resulted in symbiotic relationships between an animal and its microbial residents. The intestinal microbiome of an animal is a complex community of micro-organisms dominated by bacteria. The bacteria in the intestinal tract vary in density and species in the different compartments of the gut depending on the local environment. The gut microbiota plays a vital part in the health and well-being of its host by providing a number of benefits. The intestinal microbiota aids digestion, protects against pathogens, produces nutrients and plays a role in the development and maturation of the gut tissues and immune system. As such if the gut microbiota fails to properly develop then the gut tissues and gut immune system will also not develop correctly which will have long-term health implications for the bird.
Intestinal health is a complex area due to the wide range of management and health related factors which can impact upon the function of the gut. The gut and its resident microbiota are both dynamic entities that change as the bird ages, and understanding these changes is key to maintaining intestinal integrity to ensure optimal bird performance. Optimal brooding conditions with good access to feed and clean water are essential for optimal post-hatch gut development and long term gut health of the flock. Another key factor in the development of the villi is stimulation by the intestinal microbiota; villus length has been shown to be stimulated by lactobacilli sp. which are the bacteria which dominate the small intestine. Even though the GI tract of the developing chick in ovo is not completely sterile, the majority of colonization of the gut of the chick occurs post hatch. Sources of bacteria include the farm environment, the feed, the water supply and the litter onto which the birds are placed. The application of probiotics and competitive exclusion agents to day old chicks has been shown to aid the maturation of the intestinal microbiota and enhance the development of the gut tissues.

The Balance of Intestinal Microbiota
There is a delicate balance between the host, the intestinal microbiota, the intestinal environment and dietary compounds. An imbalance in this relationship can alter the composition of the intestinal microbiota and impact upon the integrity of the gut barrier. The shift in microbial populations can have a negative effect on the host leading to poor growth and poor performance – this is seen in cases of dysbacteriosis. Dysbacteriosis is a digestive condition of poultry and has been broadly described as an overgrowth of the intestinal microbiota leading to non-specific enteritis which can result in wet litter. Its aetiology is not fully understood but it is often seen following events which can cause physical or physiological stress on the birds such as feed changes and handling or moving the birds. Stress induced enteric upset is seen in many different animal species and has been shown to be linked to the increase in growth of certain bacterial species. The hormones released during stressful events enter the gut and the activity of certain bacteria, such as E. coli, increases which can lead to enteritis and increased susceptibility to disease. Environmental conditions also play a major role in intestinal health with a key example being the impact of heat stress on the gut. During heat stress blood is diverted to the surfaces of the bird to aid cooling, this results in reduced blood flow to the gut which can result in hypoxia and a build-up of metabolic waste in the gut tissues. The result of this is a failure of the gut barrier which reduces the efficiency of the gut and increases the risk of bacterial overgrowth and disease. Bacteria have a preferred range of nutrient sources; as such the composition of the intestinal microbiota is influenced heavily by dietary formulation. During the life of a flock there are a number of feed changes where there is a shift in energy and protein densities of diets; this invokes a change in the micronutrients available for the gut microbiota. In the event of a feed change, the gut microbiota can become unbalanced as the response to the change varies across the bacterial population and the result can be overgrowth of certain bacteria leading to diarrhea. The use of direct fed microbial products or organic acids over a feed change can inhibit the overgrowth of the less favorable bacteria during these periods and maintain gut integrity to reduce the likelihood of dysbacteriosis occurring.

Key to the Maintenance of Intestinal Health
Understanding the requirements of the developing gut to promote optimal tissue and immune system development. Furthermore being aware of how the intestinal microbiota changes at key points throughout a bird’s life and how it is possible to prepare the bird for these changes can reduce the likelihood of serious intestinal imbalances.
