Milk for Mammals

Milk is the sole source of nutrition for young mammals up until weaning. The composition of milk is very different for each species, depending on the different physiological requirements of the growing young. Click on the links below for our range of species-specific milk replacers, each based on the composition of the natural mother's milk.

    Success in hand-rearing lambs greatly improves if they receive colostrum within the 24 hours from birth. Lambs that don’t get colostrum from the mother can be fed Impact Colostrum Supplement. Commence feeding Wombaroo Sheep Milk Replacer after the initial feeds of colostrum.

    Making up Milk

    To make 1 litre of milk: Add 200g of powder to 850ml of warm water.

    Add half the water to the powder first and mix to a paste. Then add the remaining water and mix thoroughly. Pre-boil the water to ensure it is sterilised. If the water is too hot it can cause the milk to curdle. If it is too cold then it will be difficult to disperse the powder. Wombaroo contains elevated protein and fat levels, so the milk needs to be well mixed to prevent it from separating out. An electric whisk can be used for mixing larger quantities. Milk can be stored in the fridge for up to a day or can be frozen for up to 2 weeks.

    Bottle Feeding - Individual or Young Lambs

    Warm milk to about 35°C and feed from a bottle with a commercial lamb teat or Wombaroo D-type teat for small lambs. Feed every 4 hours for the first 4 days, reducing this to every 6 hours by week 1 and every 8 hours by week 2. Avoid dehydration during periods of hot weather by giving a drink of pre-boiled water between feeds. Always have clean drinking water available. Consult a veterinarian or experienced breeder for particular advice about husbandry of lambs.

    Self Feeding - Groups and Older Lambs

    Lambs can be taught to self-feed from a modified bucket with rubber teats attached to the base so that milk gravity feeds into the teats. Ensure the bucket is well-fastened and teats are at least 40cm above the floor. Milk should be offered cold (5ºC) when self-feeding, as this reduces overfeeding by lambs and milk spoilage.  Feeding milk cold reduces overfeeding by lambs and spoilage of milk.  Self-feeding lambs should drink from 0.8 to 1.1 litres of milk per day, depending on body weight.

    Growth

    Lambs should weigh from 4 to 6kg at birth and grow at a rate of 250 to 400g per day, depending on breed. Where possible, weigh lambs regularly to verify weight gains and determine the volume of milk to feed. Overfeeding milk can cause diarrhoea so feed the suggested volumes in the feeding guidelines.

    Weaning

    Ewe-reared lambs are weaned at 3 to 6 months of age. However, hand reared lambs can be weaned as early as 15 to 20 days as long as body weight is a minimum of 9kg. To entice lambs to eat solids, offer pelleted food soaked in milk. Lambs can be offered high quality, digestible feed and hay from 7-10 days of age. This starts the development of microbial digestion in the stomach. Once they start to eat sufficient quantity of solid food reduce the milk and increase the solids until they are fully weaned.
