At the 4th National Lipid Nutrition Forum, a number of experts, scholars, heads of feed industry enterprises and technical experts in the field of animal lipid nutrition gathered in Beijing and brought a technical feast on animal lipid nutrition. Tong Xiaofeng, the manager of
broiler technology of Calid, gave a speech on the topic of “Functional fatty acids: dual catalysts for health and efficiency in broiler farming” at the forum. He pointed out that the broiler industry has now entered the era of micro-profit, cost reduction and efficiency is the trend of the industry. For the broiler industry, the focus of cost reduction and efficiency is to improve feed efficiency and flock health, and functional fatty acids can improve these two points to different degrees. He also shared the results of the application of Calid’ fatty acid balancing solutions, such as Liduoneng® Core Oil, Oprimest-B and Ankesor®, in production practice.
Below is a review of the highlights of Tong Xiaofeng’s talk.
How to reduce costs and increase efficiency in the era of micro-profit
The broiler industry is currently in a micro-profit era, and feed accounts for nearly 70% of broiler farming costs. Therefore, the key to reduce cost and increase efficiency of broiler is to improve feed efficiency and flock health. At this stage, the intestinal feed digestibility of broilers is insufficient, and the nutrient deposition rate is low, which affects the breeding profit.
Common watery stools, feed stools and enteritis in broilers are all intestinal health problems. This is the main culprit for low feed utilization and economic losses.
In terms of poultry nutrition, the intestinal tract undertakes 99% of the nutrient absorption and more than 80% of the digestive activities in chickens.
To summarize, intestinal health is the prerequisite for chicken health and meat production efficiency; “health” is the cornerstone for “efficiency” to be steadily improved, and “efficiency” is the ultimate goal of “healthy” farming. Health” is the cornerstone of the steady improvement of ‘efficiency’, and ‘efficiency’ is the ultimate goal of ‘healthy’ breeding. Both of them must be “benefit from the intestines”.
Functional fatty acids: efficiency and health
Short-chain fatty acids improve feed digestibility and utilization, reduce the occurrence of disease and stress, and thus improve broiler health and efficiency.
Medium-chain fatty acids are antibacterial and antiviral by disrupting bacterial membrane structure, lowering intracellular PH, reducing intestinal bacterial colonization, inducing host secretion of antimicrobial peptides, and disrupting viral capsules.
The effects of medium and short chain fatty acids are similar, but also have their own focus. Medium-chain fatty acids have outstanding bactericidal and antiviral abilities, while short-chain fatty acids focus on intestinal protection and energy supply, and the synergy between the two can achieve the effect of “1+1＞2”. The fat emulsification effect of medium-chain fatty acids, together with the absorption-promoting effect of short-chain fatty acids, can promote the body’s absorption of lipids, and promote the realization of functional fatty acids for the maintenance of intestinal health, which is both highly efficient and healthy.
ω-3 PUFAs can inhibit inflammation, while ω-6 PUFAs are pro-inflammatory. The high content of ω-6 PUFAs in soybean oil-added diets is prone to induce inflammation in the body, leading to long-term stress in broiler chickens, which affects production efficiency and healthiness. ω-3/ω-6 PUFAs balance reduces both energy loss and inflammation, which ensures efficiency and healthiness. In addition, PUFAs improve poultry immunity.
CALID solutions for broiler
Liduoneng® Core Oil
AA broilers were used in the test, with a base fat addition of 6%, and 2% Liduoneng® core oil was added to the fat of the test group, and the fat addition was adjusted to 5.7%, and fed for 41 days.
The feed-to-meat ratio was reduced by 0.06, the survival rate was increased by 0.98%, the average daily weight gain was increased by 2.2g, the quality of feces was significantly improved, and the farming income per ton of feed was more 264 RMB.
Trial one: Cherry Valley meat chicks were selected and supplemented with 1000 g/t of Oprimest-B® and reduced by 1000 g/t of corn. The test period was 36 days.
The feed-to-meat ratio decreased by 0.052, leaving weight increased by 0.78kg, survival rate increased by 2.35%, and the input-output ratio could be more than 1:9.
Trial two: 2160 birds of 1-day-old AA broilers were selected and divided into 3 groups, the control group was fed with basal diet, T1 was fed with basal diet + 500g/t of Special Oprimest-B®, and T2 was fed with basal diet + 1000g/t of Special Oprimest-B®, and the growth performance, organ index and muscle quality of the broilers were measured. The test unit was Wuhan University of Light Industry.
The feed-to-meat ratio was reduced by 0.04-0.08, the daily weight gain was increased by 2.2-3.4g/d, and the growth performance was improved. Oprimest-B® can reduce muscle brightness and muscle yellowness, and improve the selling appearance of chicken meat. Absolute value of spleen index of the test group is increased and immunity is improved. Abdominal fat deposition of broilers in the test group is reduced, reducing energy waste.
The experiment was conducted by selecting 360 healthy 15-day-old yellow-feathered broiler chicks with similar body weights, which were randomly divided into 6 treatment groups with 3 replicates per treatment and 20 chicks per replicate. The experimental groupings are shown below.
Coccidioides immitis infection was started on day 7 and Clostridium perfringens tapping test was performed on day 15 for 3 consecutive days. The tapping dose was 1 ml (content of 1×108 CFU/ml). Data were collected on days 21 and 28.
In terms of efficiency, Ankesor® increased the average daily weight gain of broilers to varying degrees, with a dose-dependent decrease in the feed-to-meat ratio.
In terms of health, Ankesor® improved intestinal pathological damage scores and intestinal morphology, increased the body’s antioxidant capacity and alleviated the expression of intestinal inflammatory factors.
