LOSADA-CUSTARDOY, Hermenegildo et al. Effect of feeding with organic waste on the production and reproduction of dairy cows. agric. soc. desarro [online]. 2016, vol.13, n.3, pp.401-409. ISSN 1870-5472.

In order to analyze the effect of unconventional foods on the production cost of milk and its productive-reproductive variables, 32 Holstein cows were selected based on the number of labor and bodily condition. Two feeding systems were evaluated: the first one included organic wastes, commercial balanced meal and fodder (NCF), and the second used commercial balanced meal and fodder (CF). It was found that the type of diet did not influence the milk production or the interval labor-first heat, and that the number of labor (age) of the cow favored milk production and the return to the butchery after the birth. With these data, it can be stated that substituting commercial balanced meals with organic waste does not affect the productive-reproductive variables of cows, and it does decrease the production cost of milk. The possibility of milk producers from Iztapalapa substituting part of the conventional diet by incorporating organic waste is also discussed.
