Ecosistemas y recur. agropecuarios [online]. 2019, vol.6, n.17, pp.391-398. ISSN 2007-901X.  https://doi.org/10.19136/era.a6n17.1983.

The objective was estimate the yield curve and to determine the composition of the milk in Creole Obispo ewes. Milk production data of 22 ewes were processed utilizing the Wood model; dates were registered weekly using the lamb suckling-lamb weighing-milk method, while for their milk composition determination an equipment “Lactichek” was uti lized. the higher mean peak of milk production (539.60 g) was registered into the second week, while the daily performance was of 342.82 ± 11.59 g and the accumulated milk production estimation per ewe for a lactation of 12 weeks was of 30.58 ± 1.21 kg. The average values of protein, fat, lactose, total solids, no fat solids, water and density were 5.71%, 2.49%, 4.59%, 13.66% and 11.24%, respectively. The milk production curve in the “Obispo” ewe register its highest rising between the second and the third weeks post-lambing.
