While lumenal acidity is certainly important for hydrolase function, greater acidity does not necessarily equate with higher activity; in some cases, the most acidic lysosomes are in fact the least degradative57, suggesting other mechanisms may be needed to hyper-stimulate lysosomes when needed. Our ...
(summarized inDelgado, 2003;Delgadoet al.,1999). Most of the world's growth in production and consumption of these foods comes from the developing countries. Thus, developing countries will produce 63 % of meat and 50% of milk in 2020. It is a global food activity, transforming thegrain...
change during growth. Part of the inefficiency of transforming the diet into animal products is due to “overhead costs”. For example, energy is required for maintenance to sustain basal physiological processes (including thermoregulation and physical activity). However, energy is also required for ...
Another annelid relative known since the Ediacaran, this group has gutless members that get nutrients only from symbiotic bacteria and what is dissolved or suspended in the water. The Apometamera show traces of segmentation in the Echiura but none in the overall more-derived Sipuncula. Apome...
Phytate is the main storage form of phosphorus in plants and can’t be broken down by monogastrics. It is also a powerful antinutrient that binds key nutrients, making them inaccessible and reducing performance. Our phytase enzymes use phytate as a substrate. Accurate application is crucial sinc...
1. The antioxidant activity of EOs is attributed to the radical scavenging ability of hydroxyl groups that are part of a conjugated system, such as a phenol that can donate a hydrogen atom with the resulting radical resonance stabilised. Other molecules such as ascorbic acid act by donation of...
Learn about animal cells with this fun and free printable animal cell coloring activity! Coloring an animal cell model is a quick STEAM project, perfect for any time of the year. Color in and label the parts of an animal cell as you explore what makes animal cells different from plant cell...
However, deficient or excessive availability of one or more important nutrients often reduce the overall cultured animal productivity when animal wastes are used alone as the main protein source in aquaculture feeds (Fasakin et al., 2003). As a result, combination of animal wastes for partial or...
While in the manufacture of fertilizers, the granulation of urea is known, the simple addition of micronutrients, iodine, or other essential nutrients to a urea granulation process can potentially cause processing problems such as agglomeration, dusting, excess moisture and low production rate. Physical...
