Document Summary

Growth and development of carcass tissue: production of meat and other foods is dependent on the growth process, growth is a fundamental process to the livestock and meat industries. An increase in structural tissues such as muscle, bone, and vital organ: fattening. An increase in adipose fat: need to be considered separately when applied to practical animal production. Prenatal growth (conception to birth: ovum (zygote) phase: from fertilization to implantation, embryonic phase: the period after implantation; major organs and structures are formed, gastrulation phase. A single layered blastula is developed into a three-layered embryo known as gastrula: the prenatal period. Increase in cell number (only occurs in pre-natal) Increase in cell size (before and after birth) Increase in extracellular material or intercellular material: all changes in muscle after birth are a result of hypertrophy or atrophy. Muscle fiber hypertrophy: due to accumulation of myofibril proteins, growth in length precedes growth in diameter.
