The Edit

AN OPPORTUNITY AHEAD

The good news in our fight and challenge against the COVID-19 menace is that our poultry industry has restored itself to near-normalcy in three- fourths of the country. These areas have seen no or only a few cases of the virus infection. The bad news, however, is that economic activity is located disproportionately across the country and the timetable for reviving poultry industry and economic progress in some areas is uncertain. In the near term, there is added uncertainty of a severe wave of avian influenza infection in many states. Bird flu has seen two major waves in 2006-2007 and again in 2008-2009. The recent bird-flu episode in 2020- 21 killed and destroyed (as a precautionary measure), a large number of birds in some states of the country. Only in Maharashtra, the number of destroyed birds exceeded more than a million. Prospects of overcoming these challenges and returning to full normalcy for the poultry industry are far more certain in one to one and a half years. The team piloting these poultry reviving projects says that the industry will come back to the previous form at pre COVID-19 level as early as the end of 2021. While the government must accord priority to meeting the immediate challenges posed by COVID-19 and avian indfluenza, it is also time to begin strategising for the longer term economic transformation. As the saying goes, never let a crisis go to waste. While the sequencing of steps to restart the poultry economy after the lockdown must be the topic of the day, we must also cast our eyes a little further ahead to opportunities that will emerge after the crises. We must avail the opportunities opened for poultry producers through poultry processing. In a recent report it has been pointed out that after this pandemic crisis, the demands for processed poultry meat have grown significantly to 18-22% globally, and in our country the demand has crossed more than 15 to 16% from 8 to 9% in pre-COVID times. Our poultry industry must avail this opportunity.

World Mycotoxin Survey: Impact 2021

Everything you need to know about upcoming The Global Mycotoxun Threat 2021 mycotoxin threats to poultry, swine, ruminants and aquaculture worldwide. The BIOMIN Mycotoxin Survey constitutes the longest running and most comprehensive data set on mycotoxin occurrence. The survey results provide insights on the incidence of the six major mycotoxins in the agricultural commodities used for livestock feed in order to identify the potential risk posed to livestock animal production.

HIGHLIGHTS:

1. BIOMIN is a leading company in mycotoxin deactivation and analysis. With the help of cooperation partners we are able to present to you results from: 96,684 analysis, done for 21,709 finished feed and raw commodity samples from 79 countries between January and December 2020! 2. The globally most prevalent mycotoxins are still DON (65%) and FUM (64%). 3. ZEN is also highly prevalent (48%) with an average of 139 ppb globally. 4. In North America the risk stays extreme. DON was present in 72% of corn samples and in 89% of cereal samples. Aver- age of positives for DON in corn (maize) was quite high with 808 ppb and even higher in cereals (1,721 ppb). Corn was also affected by FUM and ZEN with averages of 2,405 ppb Risk Level: The risk level and 323 ppb, respectively. expresses the percentage of samples testing positive for at 5.

Threshold levels in parts per billion (ppb): In wheat, DON is the main threat (83% of the samples; av- erage of 1,584 ppb). In Soybeans ZEN was most abundant (73%), followed by T-2 (51%) and DON (46%). 6. Europe: Risk is high to severe. The most prevalent mycotox- in is still DON, followed by ZEN and FUM. DON is the main threat for livestock, with 70% of corn samples positive, but cereals were also affected: DON reached a maximum con- centration as high as 11,875 ppb. ZEN increased its average contamination in corn to 171 ppb. 7. Asia: Risks are extreme in South Asia, China and Taiwan and severe in Southeast Asia and East Asia. FUM occurs in 96% of corn, followed by DON (80%). ZEN is also a risk: It was present in 68% of the samples analyzed (maximum 11,786 ppb). In this region, Aflatoxin remains a main threat for animals.

Precision Trace Mineral Nutrition

Dr. Sabiha Kadari and Dr. Rajesh Pittala Trouw Nutrition India

race minerals are essential for various metabolic and biological processes within the animal’s body. Given their Timportance in physiological processes, they play a vital role in growth, production and reproduction of animals. Numerous contin- uous researches have been conducted with respect to the trace mineral requirements of animals according to their age, production stage, stress conditions etc. The notion of “The more the better” does not apply to trace mineral nutrition, wherein higher levels of supplementation do not result in improved animal performances. Precision needs to be practiced with respect to the optimal supply of trace minerals that would be biologically available to the animal to carry out its metabolic functions. Practicing this precision trace mineral nutrition is essential for optimizing production cost, decreasing environmental pollution and im- proving animal productivity and well-being.

Toxic substances Toxins such as mycotoxins, heavy metals and some poisonous plants can have a serious effect on the physiological perfor- mance of the liver. Aflatoxin, one of the most toxic mycotoxins identified in nature, can cause fatty vacuolation and hepatocyte necrosis. Also, bile duct epithelial hyperplasia and fibrosis can be detected. It is important to point out that Aflatoxin will affect the mitochondrial and protein synthesis capacity of the liver, which means that the organ will not be able to manufacture critical substances normally secreted by the body. Mycotoxins such as T2 toxin can also damage the hepatocytes causing hemorrhage and necrosis. The presence of pale bile content (bilis) is associ- ated with Aflatoxin because of a reduction in amylase, lipase and biliary salts production by the liver. The final result is the presence of excessive levels of fat in feces (steatorrhea), which is difficult to detect grossly because Picture 1. Normal liver (yellowish, pale) in a laying hen to the right and chicken excrete urine and feces together through the cloaca. a dark brown liver of an out of production hen to the left. The bile also contains amylase, which aids in the digestion of carbohydrates as well as activation of the pancreatic lipase. Regarding the effect of Fumonis in the liver, we must emphasize that even though the performance (gain weight, feed conversion, etc.) of the flock could be affected, this toxin does not cause distinctive macroscopic changes in the liver, even when 100 ppm of Fumonisin were added experimentally to the diet in a scientific trial. Macroscopically (gross appearance), only certain degree of paleness has been reported. The damage to the liver is established by measuring the concentration of metabolites (biomarkers) of sphingolipids (sphinganine/sphingosine) in the blood and a reduction in the concentration of protein in the blood. Microscopically, some scientific papers have reported hyperpla- sia of the bile ducts, as is reported in cases of aflatoxicosis.

Management practices n Fasting before slaughtering This is a factor that is more important and common in broilers because of the traditional management practices followed in this type of birds. Generally, the access to feed is interrupted for approximately 12 hours before broilers are slaughtered with the objective of reducing fecal excretion to avoid cross contamination during transportation and the possibility of fecal contamination of the carcass during automated evisceration in the slaughterhouses. One of the consequences of fasting is the presence of changes in the color of the liver. Scientific reports have shown that full-fed broilers have lighter liver colors because of higher lipid con- Picture 2. Liver of a 46-week-old brown layer fed a diet experimentally tent.
