Animal Health&Nutrition--Middle East & Africa

The intestine is a digestive, absorptive, and immune organ, and the liver is an organ that aids in digestion, excretion, and immune regulation. The health of these two major organs determines the health of the animal's body. How does the liver (bile acids) affect gut health? Check the article to know more... #poultry_health #Animal_feed #LachanceGroupBroilerNutrition #Lachance_bileacids

The weight and uniformity of chicks during the brooding period are two key factors affecting the production performance of laying hens.  Practical experience has proven that there is a significant positive correlation between the weight of pullets at 5 weeks, laying rate, and average egg weight. If the weight of 5-week-old pullets is high, the entire flock will start laying early and have a long-lasting peak period. ln addition, the survival rate will be higher and the death rate will be lower throughout the laying period. In conclusion, the management of chicks during the rearing period needs to start from the physiological characteristics and feeding management. #poultryhealth #poultrynutrition #poultryfeed

The most common problems in tilapia production in intensive systems and ways to address them are as follows: 1. Water Quality Issues: - Problem: Accumulation of waste products (ammonia, nitrites, nitrates) and depletion of dissolved oxygen in the water. - Solution: Implement efficient water treatment and recirculation systems, such as biological filters, oxygenation units, and water exchange protocols. 2. Disease Outbreaks: - Problem: Increased susceptibility to bacterial, viral, and parasitic diseases due to high stocking densities. - Solution: Maintain strict biosecurity measures, implement prophylactic treatments, and optimize feeding and management practices to promote fish health. 3. Feed Management: - Problem: Improper feed formulation, over-feeding, or suboptimal feeding regimes leading to poor growth and feed conversion. - Solution: Develop customized feed formulations based on the specific nutritional requirements of tilapia, and implement precise feeding protocols. 4. Stunted Growth: - Problem: Uneven growth rates and stunted individuals due to social hierarchies and competition for resources. - Solution: Implement grading and size-sorting protocols, control stocking densities, and provide appropriate environmental enrichment. 5. Genetic Deterioration: - Problem: Inbreeding and loss of genetic diversity leading to reduced growth performance and disease resistance. - Solution: Establish breeding programs with regular genetic monitoring and introduction of new genetic material to maintain genetic diversity. 6. Oxygen Depletion: - Problem: Insufficient aeration and oxygen supply, especially during hot weather or high biomass periods. - Solution: Install high-capacity aeration systems, such as diffused air or mechanical aerators, and implement efficient oxygen monitoring and management. 7. Ammonia Toxicity: - Problem: Accumulation of toxic ammonia due to insufficient nitrification or inadequate water exchange. - Solution: Optimize biofilter design and capacity, maintain appropriate carbon-to-nitrogen ratios, and regularly monitor and manage water quality parameters. 8. Handling and Harvesting Stress: - Problem: Injuries, mortalities, and reduced growth due to improper handling and harvesting techniques. - Solution: Develop and implement standard operating procedures for safe handling, grading, and harvesting of tilapia, and train personnel accordingly. By addressing these common problems through a combination of technical, management, and biosecurity measures, tilapia producers can improve the overall efficiency and sustainability of their intensive production systems. #Intensive_Aquaculture #RAS_system #biofloc #Tilabia #fresh_water

#Eggshell quality is an important aspect of egg production, it will affect both the egg's marketability and the health of the developing embryo inside. Egg quality will decrease with the increase of the age of laying hens and the digestive parameters such as bile acids content, lipase, and trypsin in laying hens.

The quality of chicken is affected by many factors, from production to slaughtering, sales, and storage, there are some factors affecting the quality of chicken. #chicken #poultry #meat

The feeding and management of #broiler chickens varies at different stages of their growth and development. Bile acids can be added at various broiler-raising stages to enhance immunity and improve production performance.

New idea for #heat_stress problems. The negative impacts of heat stress (HS) on growth performance and lipid metabolism have been reported, but there are still no effective nutritional strategies to alleviate heat stress. #Bile_acids are new for their antioxidative properties and regulatory effect on lipid metabolism. This study was carried out to evaluate the #growth_performance and #lipid_metabolism in chickens under heat stress when fed with bile acid supplements in their diet. The results showed that mild heat stress (32 °C) induced hepatic lipogenic gene (hepatic SREBP-1c) expressions and lipid deposition, without obvious tissue damage in broilers. Dietary supplementation of bile acid could decrease hepatic lipid deposition without affecting endogenous bile acid biosynthesis. Therefore, bile acid supplements can benefit broiler chickens during high ambient temperatures, serving as a new nutritional strategy against heat stress.
