@Ernestomaria Ene Dear, It's a quite new idea that plant extracts play effective roles in coccidiosis control. I always believe the conventional anticoccidials and anticoccidiostats work better. In recent years,I find in the market a few products are available for such application. We can share the information on such products.... Thank you....

Consumers often find goose meat low in tenderness, possibly because of conventional commercial methods of chilling carcasses. Goose is a popular dish in Taiwan, where a recent study tested "stepwise" chilling with calcium chloride incubation to improve muscle proteolysis and meat tenderization.
Conventional commercial goose processing involves submerging carcasses in ice-cold water right after harvest, which induces "cold shortening" of...

There is increasing evidence that supplementing small amounts of prebiotic xylo-oligosaccharides (XOS) into poultry diets has positive effects on bird performance and gastrointestinal health. Soluble XOS that reach the caeca intact are utilised by beneficial bacteria, inducing positive effects such as increased production of short chain fatty acids (Aachary & Prapulla, 2011). Commercial endo-xylanases are added to diets to reduce digesta viscosity, but have the side effect of producing...

I. Introduction Typical Australian broiler diets contain 2.5-3.0 g/kg phytate-P or roughly 10.0 g/kg phytate; therefore, phytase is included into every Australian broiler diet. As phytase is capable of increasing the availability of phosphorus, calcium, sodium, amino acids and energy content of diets, these nutrients may be decreased in the feed formulations as ‘matrix values’ without adverse effects on the birds’ growth performance (Dersjant-Li et al. 2020)....

Trace minerals are often supplied in the forms of inorganic salts such as sulphates into poultry feed to meet the requirements. The ionic bonds in inorganic salts of minerals are very weak allowing the metal ion to disassociate once in contact with water, binding up diet antagonists such as other minerals, vitamins, and enzymes. To mitigate these negative effects technologies such as organic minerals or mineral complexes, which are less reactive, are used. In hydroxychloride minerals (Hyd)...

I. Introduction Salmonella spp. in poultry pose a serious risk for food safety. The complex nature of Salmonella infections in poultry requires a multifactorial solution. It is key to preventing Salmonella colonization throughout the entire gastrointestinal tract (GIT). Short chain fatty acids (SCFA) have been described as having beneficial effects in the upper part of the gut, whereas medium chain fatty acids (MCFA) target the lower GIT (Van Immerseel et al., 2009). Coated butyrate...

I. Introduction Poultry diets are currently formulated based on total calcium (Ca) and available phosphorus, with a ratio of 2:1 being maintained between them. For a number of reasons, there is increasing interest in shifting the formulations based on digestible Ca and digestible P. To enable this move, information is required of the requirements of digestible Ca and digestible P. A recent study at our laboratory (David et al., 2021) determined the standardised ileal digestible (SID)...

I. Introduction Wheat and sorghum are the two major feed grains used in Australia for broiler diets; however, wheat is more common and is usually considered better quality than sorghum. The local chicken meat industry may have to increase by 60% to meet demand in 2050 so strategies are needed to promote sustainable chicken-meat production to meet this anticipated demand. Crude protein reductions in broiler diets could be a major factor in the quest for sustainable production....

As in commercial broiler chicken production, broiler breeder performance depends upon adequate dietary trace minerals, including zinc (Zn), manganese (Mn), and copper (Cu). Broiler breeder diets currently used in the industry contain levels of the inorganic forms of these minerals with generous safety margins. Researchers now report that combining inorganic sources of Zn, Mn, and Cu with organic hydroxy analog of methionine (HMTBa) forms in breeder hen...

We know that young geese benefit from warmer drinking water, but what is the optimal water temperature? Poultry scientists take a closer look
A new investigation into goose health suggests providing drinking water that is at least 18? (64.4?) may boost the activity of digestive enzymes, promote intestinal development, increase water consumption, and even increase goose eye temperature. Based on their findings, the...

Particulate matter (PM) can damage bird lungs. Now poultry scientists gather data to give a fuller picture of the effects of PM in different housing systems
Poultry scientists are working to better understand the impacts of particulate matter (PM) on bird health and production. Particulate matter includes very small particles of feed, feathers, animal waste, and dander. Researchers have found that PM...

I. Introduction Methionine plus Cysteine (Cys) requirement of poultry and swine has been determined using graded levels of DL-Met. Currently, Aviagen recommends 0.95, 0.87, and 0.83% SID Met plus Cys for starter, grower, and finisher phases of Ross 308 broilers (Aviagen, 2019). Cobb recommends 0.88, 0.80, and 0.74% SID Met plus Cys for the respective growth phases (Cobb, 2018). Similarly, Brazilian tables recommend 0.99, 0.97, and 0.91% SID Met plus Cys for broilers starter, grower,...

I. Introduction Phytase, apart from increasing phosphorus (P) availability from plant ingredients, improves availability of non-P nutrients like Ca, amino acids (AA), and energy (AME) by facilitating the breakdown of phytate P and thus negating its antinutritional effects (Dersjant-Li et al. 2016). Phytase along with carbohydrase enzymes could improve productivity of chickens with a lower feed cost when proper downspec (reduction of nutrient levels in the diet) is applied. It is...
