From weekly averages of recorded data of dry matter consumption, milk yield and live weight, the level of voluntary food intake by lactating goats can be predicted for the whole lactation and more accurately for mid-lactation. The models for predicting daily dry matter intake and forage intake were set up by multiple stepwise regression. Total dry matter intake depends mainly on milk yield, live weight, corrected live weight gain and hay percentage of the diet. The study showed that the dry matter intake of lactating goats was higher than that of lactating cows when expressed per kg live weight, but the intakes of goats and cows were similar when expressed per kg metabolic weight. |

Spittlebug egg survival and hatching was compared in pastures where differences occurred in vegetative characteristics and grazing intensity. Egg samples were placed in pastures at the start of the dry season and recovered before hatching began. Significantly (P<0.05) more eggs were recovered from areas where litter was present than from bare soil areas. Mortality from predators and scavengers was estimated at 73%. An additional 34% of the eggs were desiccated and 35% were nonviable. Egg survival was estimated to be 8,5% and was greater in pastures with the following characteristics: 1) canopy height > 30 cm; 2) abundant litter; 3) plant cover < 50%;4) minimal or no grazing. More predators, especially spiders (Araneida) were also collected from these types of pastures. At one site more eggs halched in a high grass pasture (74%) than in a low grass pature (59%). Although high grass may receive less damage from spittlebug feeding the disadvantages of maintaining grass > 30 cm appear to outweigh the advantages. |
