Behavior of sheep fed different sequences of ingredients in a spineless cactus ("Nopalea cochenillifera Salm-Dyck") based-diet

Resumo

The purpose of this experiment was to evaluate the ingestive behavior of sheep fed diets containing different sequences of ingredients of a spineless cactus based diet because of the paucity of available information regarding the best method of feeding, especially in relation to the use of spineless cactus. The observed variables were daily time of eating, ruminating and idling. Five sheep were distributed into a 5 × 5 Latin Square with five treatments, five animals and five periods, the treatments 1 – (TMR, total mixed ration) at 7:00 and 15:00h; 2 – (C, concentrate) at 7:00h, (SC, spineless cactus) at 8:00 h, (C) at 15:00h and (TGH, tifton grass hay) at 16:00h; 3 – (C) at 7:00h, (TGH) at 8:00h, (C) at 15:00h and (SC) at 16:00h; 4 – (SC) at 7:00h, (C) at 8:00h, (TGH) at 15:00 and (C) at 16:00h and 5 – (TGH) at 7:00h, (C) at 8:00h, (SC) at 15:00h and (C) at 16:00h. No treatment effect on feeding activities (hour/day) in time total daily, but when activities were divided into periods, the sheep in sequence 3: concentrate/ hay/ concentrate/spineless cactus spent a longer time eating within the period from 7:00 to 11:00h than the sheep in sequences 1: total mixed ration (TMR) and 2: concentrate/ spineless cactus/ concentrate /hay. The digestibility of dry matter and matter organic was greater for concentrate/ spineless cactus/ concentrate/ hay and spineless cactus/ concentrate/ hay/ concentrate being recommended the use of the same as feeding strategy.
