Theme: im An al feed AGRICULTURAL Feeding of and caring for the ram lamb The ram makes a phenomenal contribution to successful herd management and improve- ment. The genetic potential of the ram lamb is already affected by the management prac- tices of the producer from six weeks before birth.  By Giepie Calldo Peritum Agri Institute follicle development takes place from birth and for three weeks thereafter. energy to 16% protein in respect of her nutrition. his is the period during which the growth of the fetus, primary wool follicle development as well as udder tissue development take place. The growth of the fetus at this crit- ical stage will eventually determine body mass; primary wool follicle development will determine wool production and udder tissue development is required to ensure that the ewe will have sufficient colostrum and milk production to feed the ram to full potential after birth. The secondary wool FEEDING AND FETUS DEVELOPMENT At six weeks before birth, is when the eventual growth potential of the fetus can receive the most damage due to incorrect feeding. Apart from the lost potential due to malnutrition, it can also result in low birth mass (2 to 3kg) and mortalities. The feed requirements of a pregnant ewe are 3,5% of her body mass. Well- balanced nutrition is necessary for the production of good colostrum, which determines the immunity of the ram over his lifespan. Maintain a good ratio of 68% FEEDING OF THE RAM LAMB AFTER BIRTH In order to optimally feed the ram lamb, the lactating ewe requires 4,5% of her body mass as daily feed. Creep feeding must be set up from 10 days after birth and is essential since it will determine the ram's eating pattern over its lifespan. The ability of the ram to adjust to its feed, is essential since rams often change owners and feed patters as a result. Feed chang- es can result in infertility since it takes approximately 21 days for the micro-or- T 04 SENWES SCENARIO | WINTER 2019
