Nutrient requirements for growth

the minimum CP requirements for maintenance of sedentary and more active horses are predicted as 1.08 and 1.44 g/kg/day, respectively. 

The recommended lysine requirement of horses for maintenance and exercise is calculated as 4.3 per cent of the CP requirement. 

Animal growth and animal nutrition are inherently finked, in the sense that one can influence the other. The growth pattern of an animal determines its nutrient requirements. Conversely, by altering its nutrition, an animal s growth pattern can be modified. Another aspect of this interaction is that the growth pattern of an animal determines the composition of the product of growth (i.e. meat), and so affects the consumer of meat, man.

Derived plant and animal products make better use or upgrade the nutritional quaHty of already existing materials or products. Synthetic and manufactured products arose from knowledge of the functional properties of food ingredients and of human and animal nutrition that involved more precise definition of nutrient requirements for growth, reproduction, lactation, and body maintenance in both humans and domestic Hvestock. Pood products have been developed to meet human needs under abnormal environments, eg, military rations for arctic, tropical, or desert environments, and special products for astronauts ia space flights. 

Semifermentation Process. In this process, the metaboHc intermediate in the amino acid biosynthesis or the precursor thereof is added to the medium, which contains carbon and nitrogen sources, and other nutrients required for growth and production, and the metaboHte is converted to the... 

Lactation provides the newborn with all nutrients required for growth and development and antibodies that confer passive immunity. 

Because there is no growth during the stationary phase, it is clear that Eq tion (7-70) cannot be used to account for substrate consumption, nor can the i of product formation be related to the growth rate (e.g.. Equation (7-63)]. M. antibiotics, such as penicillin, are produced in the stationary pha.se. In this phi the nutrient required for growth becomes virtually exhausted, and a different nc ent, called the secondary nutrient, is used for cell maintenance and to produce desired product. Usually, the rate law for product formation during the station phase is similar in form to the Monod equation, that is.
