Int. J. Biosci. 9(4), 365-368, October 2016.



This research was conducted in order to learn the effects of birth type (single or twins) in goats and sex of kids upon milk lactose levels. Therefore, 14 native goats (kıl) based on birth type and another 14 native goats (kıl) based on sex of kids were divided into two groups. Milk sample for once was obtained from the kids in the 3rd and 4th weeks of lactation. Lactose levels were specified as the mean of two weeks. As a result of series of analysis, no statistical differences were found in terms of milk lactose levels in the goats giving birth to female and male kids. However, it was found that birth type had a significant effect on milk lactose level. Also, it was found that milk lactose levels of the goats giving birth to twins were lower than milk lactose levels of the dams giving birth to one offspring. According to the results of the research, it can be said that it will be relatively advantageous for the ones showing mild lactose intolerance to prefer milk of the goats giving birth to twins.
