Interpretive Summary: Effect of nutritional supplementation upon colostrum quality in goats under rangeland conditions in Northern México
By: Anne Wallace
Colostrum is the first milk produced after gestation, which is very concentrated in both protein and antibodies. In this December 2019 ASAS-CSAS Annual Meeting and Trade Show abstract published in the Journal of Animal Science, researchers evaluated how nutritional supplementation in prepartum grazing goats affected colostrum quality.
Half the goats in this study were fed a nutritional supplement consisting of chicken manure, wheat bran, sorghum, molasses and salt, while the other half were not (the control group). Postpartum, colostrum quality was analyzed between the control and supplemented groups. Increases in lactose, but not fat, of colostrum was found in the supplemented group, compared to the control group. Body condition score (BCS) was also increased in goats in the supplemented group, compared to the control group.
Overall, this study suggests that nutrient supplementation may potentially affect colostrum quality, although a more detailed study to look at the effects of different types of nutrient supplementation may be warranted.
