Asian Agribiz’s Broiler Feed Quality Conference (BFQC) held its live sessions in Bangkok on November 28-29, delving deeper into how producers can get more out of corn-soy diets, how to manipulate digestion and absorption in the gut, and ways to assess potential alternative feed ingredients. Below are some highlights.
Protein levels in diets can be reduced with amino acids
Proteins levels in the diet can be reduced safely with a balanced amino acid profile. Miriam Alberto-Tempra, Consultant Nutritionist at Bright Side Consulting, said proteins/amino acids are the second most expensive nutrient, and producers can fully utilize them with proteases. Meanwhile, carbohydrates from plant materials would require carbohydrases. “NSPs, with arabinoxylans are the most predominant, are anti-nutritional factors that must be identified and characterized. We must find solutions to them,” she said. Dr Alberto-Tempra explained that enzymes, particularly proteases and carbohydrases, support feed efficiency and sustainability.
The balancing act: as few antibiotics as possible
Producers should use as little antibiotics as possible, and only when necessary. Susanne Kirwan, Global Technical Service Manager-Intestinal Health at Kemin, said few producers have achieved antibiotic-free production. Of their production, only 60% marketed as antibiotic-free. The rest are marketed conventionally, as some chicken houses require treatment. Without antibiotic use, there will be higher mortality, poorer FCR and ADG of the survivors, and zoonotic disease risk for workers and consumers, she said. However, prevention is better than treatment. For example, feed is an essential component of biosecurity, and producers should manage their feed vehicles, feed, and equipment accordingly.
Using protease beneficial whatever the protein level
Using protease in the feed is beneficial regardless of the protein level. Jung Min Heo of the Department of Animal Science and Biotechnology at Chungnam National University said if producers use protease in a high-protein diet, it could help with protein digestion, with a lower expression of the nitrogen in the feed. “Either with high or low protein levels, you benefit more from the protein when using protease,” he said. Dr Jung said the South Korean government has tried to reduce the protein level in the feed due to the environmental impact of carbon, limiting the levels for starter feed and grower feed.
China feeling the pinch of global grain market trends
Several trends are present in the global grain market, said Darin Fredrich, Director of Market Research at Sitonia Consulting. In China, the economy and the housing market are slowing, which is bad for commodity demand. “It is weighing on the bulk shipping demand, which is pushing down the shipping rates,” he said. Meanwhile, the CNY is declining due to a strong USD and the weakness in the Chinese economy. These could impact grain imports. When the currency is weaker, it makes imports less competitive, he added. Also, with Ukraine corn supplies disrupted by the war, China is sourcing more from Brazil.
Formulating and sourcing alternative ingredients
Matthew Clark, Director of FeedGuys Resources, offers some tips on formulating and sourcing alternative ingredients like DDGS. Alternative ingredients are finite in supply, but they are to use them when the prices of main feed ingredients are high. “A good nutritionist is always looking for alternative ingredients all the time. It should be done in a closed season and quiet market,” he said. He noted that DDGS is a good source of amino acids and available phosphorus. But variable fat levels in DDGS depend on the production process. It is important to know the type offered by different suppliers. “Different suppliers and different processes will have slightly different DDGS output,” he added.
