Vitamin A deficiency or critical excess has negative effects on the growth performance, slaughter performance, and meat quality of goslings

Metabolomic comparison of meat quality and metabolites of geese breast muscle at different ages

“…Birds were stunned using a stun bath and exsanguinated by severing the jugular vein and carotid artery on one side of the neck. The left breast muscle of each goose was divided into two parts; one part was used to measure water-holding capacity, shear force, color, pH and for texture profile analysis (TPA) ( Xiao et al, 2021 ); the other part was maintained in a sterile polythene bag and stored at 4 °C. Sterile breast muscle of geese was divided into two groups based on goose age (Y and A).…”

Effects of dietary paddy rice on growth performance, carcass traits, bare skin color, and nutrient digestibility in geese

“…The pH value was recorded 45 min after slaughter using a portable pH meter (pH-STAR, Matthaus, Berlin, Germany). According to the method of Xiao et al. (2021) , the cooking loss and shear force were measured using a thermostatic water bath (DK-S24, Shanghai Jinghong Experimental Equipment Co. Ltd, Shanghai, China) and a digital tenderness meter (C-LM3B, Tenovo, Beijing, China).…”

Nutritional Balance Matters: Assessing the Ramifications of Vitamin A Deficiency on Poultry Health and Productivity

“…(1) Reduced growth, high mortality, and poor feed conversion: Poultry suffering from vitamin A deficiency often display stunted growth rates and inefficient feed conversion, affecting various species such as chickens, turkeys, ducks, geese, and Japanese quail [11,[94][95][96][97][98][99]. This can be attributed to the crucial role of vitamin A in cell differentiation, tissue repair, and protein synthesis, all of which are essential for optimal growth.…”
