Polvillo de nuez pecan como ingrediente alternativo en las dietas de gallinas de postura: comportamiento productivo y color de yema

Abstract

One hundred and twenty laying hens were used in a six-week trial to evaluate the influence of partial replacement of feed with pecan shelling by-product (PNP) on performance and egg yolk color. Treatments consisted of feed for laying hens containing 0%, 2.5%, 5.0%, or 7.5% of PNP (as fed basis). Partial replacement of feed with increasing levels of PNP did not affect (P>0.10) performance or egg yolk color. It is concluded that partial replacement of feed with PNP could marginally reduce feed cost and improve local feedstock utilization without affecting animal performance and egg quality.
