Preliminary results of the effect of a non forage diet on lactating goats
[Eight Saanen nannygoats at beginning, half and end of lactation, divided into 2 groups, were fed a control diet (C) containing Italian ryegrass silage, corn silage and soybean meal and a non forage diet (NF) containing, as main ingredients, sunflower seed meal, cassava and coconut meal. Compared to...

Summary: | [Eight Saanen nannygoats at beginning, half and end of lactation, divided into 2 groups, were fed a control diet (C) containing Italian ryegrass silage, corn silage and soybean meal and a non forage diet (NF) containing, as main ingredients, sunflower seed meal, cassava and coconut meal. Compared to control, NF diet increased DM intake at beginning (+23%) and half (+17%) lactation and reduced DM digestibility (6 - 8%) in all stages; milk production and protein content were unaffected, while fat content increased; the productive efficiency, related to ingested DM, decreased]
Una dieta di controllo (C) contenente insilato di loiessa, silomais e un mangime a base di mais e di farina di estrazione di soia e una dieta priva di foraggio (NF), costituita da una miscela commerciale a base di farina di estrazione di girasole, di manioca e di panello di cocco, sono state somministrate a otto capre Saanen a inizio, meta' e fine lattazione. Rispetto al controllo, la dieta NF ha fatto registrare: una maggior ingestione di SS a inizio (+23%) e meta' (+17%) lattazione; una minor digeribilita' della SS (6 - 8 punti %) in tutti gli stadi; produzione lattea e tenore proteico del latte simili; maggior tenore in grasso del latte; minor efficienza produttiva, se rapportata alla SS ingerita |
