MONTEJO, I.L; LAMELA, L; SANCHEZ, Tania    LOPEZ, O. Technical note: Milk production with citrus pulp silage. []. , 31, 2, pp. 1-1. ISSN 0864-0394.

Ninety tons of citrus pulp silage were elaborated with the objective of evaluating their effect on milk production in medium potential cows. The silages were made by means of the technology of successive layers; the conservation time was prefixed at 60 days. The measurements were: DM, CF, CP, N-NH3/Nt (%) and pH. Six F-2 (75% Holstein x 25% Zebu) cows were used, distributed in a Switch Back design for studying the following diets: A) grazing ad libitum (16 hours); and B restricted grazing (8 hours) plus silage (90% citrus pulp plus 10% sugarcane bagasse) ad libitum. Both treatments received 0,5 kg of commercial concentrate at milking. The stocking rate was 1,1 cows/ha and only one milking a day was performed in the morning hours. The silage intake (humid base) was 13,9 kg/animal/day (treatment B) and significant difference was found (P<0,05) for milk production between treatments A (7,3 kg/cow/day) and B (6,4 kg/cow/day); however, no variations were observed in the percentages of fat, crude protein, non fatty solids and total solids; a change in the body condition of the animals was not observed either during the whole experiment. It is concluded that the addition of bagasse allowed to preserve the citrus pulp in the form of good quality silage (CP 6,5% and pH 3,7) and the milk production was 6 kg/cow/day.
