Paper Abstract: This study analyzes hand-raised cub feeding and mass development data using the same hand-raising protocol and milk formula for Bornean sun bear (Helarctos malayanus euryspilus) cubs. This data was collected at the Bornean Sun Bear Conservation Centre in Sabah, Malaysia. We use generalized linear mixed model with random effects to assess disparities between sun bear cub (n = 10) mass gain (x̄ = 13.09 kg, s = 4.66 kg, Range 4.40-27.45 kg) and differences between male and female hand-reared cubs based on greater than 1000 daily or semi-weekly measurements recorded since 2013. We found lower mass gain in females (x̄ = 11.8 kg), compared to males (x̄ = 16.1 kg), and model results suggested sexual dimorphism as the cause between male and female average mass. The model identified significant variables as the individual bear, age, and the body mass percentage of milk fed. Milk formulation was varied by individual health metrics, and feedings were calculated using ml per kg. Additional research should assess sun bear milk composition to more closely simulate milk.
