Abstract : From weaning 50 ewe lambs were maintained on annual grassland range pasture which provided adequate feed for only 2 or 3 months in spring, followed by a dry season until early winter. This barely maintained weight for 6 months after weaning and allowed a slow gain until breeding the following year. From Julyto April50 similarlambs were kept on irrigated pasture of ladino clover and trefoil supplemented with lucerne hay to appetite from November to April. This promoted continuous growth. They were then transferred to the range pasture and both groups were kept there for 5 to 7 breeding seasons. The only supplement given was a mixture of salt and cottonseed from mating until the end of the dry season each year. Ewes which had been reared on good pasture were 34% heavier as yearlings than those reared on the range and remained significantly heavier until 41/2 years old and in some the difference was still seen at 6 years. They had greater heart girth and height at withers after a year on range and produced significantly more wool at the first and third shearings but at no other. They lambed significantly earlier, 8 days, in the first year; in subsequent years they lambed 2 to 3 days later than the other group. They raised fewer lambs per ewe in the 7 seasons but frequency of twins and weights of lambs at 120 days were the same in both groups. Total weight of lambs per ewe and lambs weaned per ewe were less in those given poor pasture at the start.-J. G. Gordon. |

Considering its high demand and limited production, raisin represents an important alternative to diversify grape processed products around the world. The aim of this study was to determine the best combination between drying temperature and time required to reach the highest consumer acceptance of ?Italia? raisin produced in the semi-arid climate in Brazil. The drying conditions were combinations between drying temperatures of 50, 56, 70, 84 and 90°C and drying times of 16, 22, 35, 48 and 54 hours, following a central composite rotational design (CCRD). The best combination between drying temperature and time was estimated to be 70°C for 35 hours (h), based on overall consumer acceptance. According to the statistical analysis used, drying at 70 °C for 35h and at 59 °C for 28h results in equal overall consumer acceptance, being the second option the more economical. Taste and texture, raisin chroma values and pH were more positively correlated to overall acceptance. The results indicate that drying at 59ºC for 28 h is the most efficient drying condition for raisins from ?Italia? grapes grown in Brazilian semi-arid condition. This study uses a new approach based on the central composite rotatable design to determine the most efficient drying temperature and time for Italia raisins. |
