1 st WorkshopXIII International Feed Technology Symposiumthe basic factors influencing protein synthesis and concentration are still not sufficientlyknown.Table 5.

During the initial period of lactation, lower quantities of concentrate inthe ration have no unfavorable effect on milk production if goats have sufficient bodyreserves accumulated during late gestation. Namely, to maintain the persistence oflactation, it is recommended to fortify nutrition from the fifth month, until the end oflactation, to enable goats to accumulate body reserves. It is deemed that the program ofnutrition for dairy goats should be regarded an annual cycle during which proper goatnutrition is very important to enable formation of body reserves. Thus, during theproduction cycle, goats can mitigate variations that may appear relevant to their needsfor nutritional substances for production, and at the same time be able to adapt to variousconditions of nutrition.REFERENCES1.
