Lamb Production from Booroola X Collinsville Ewes
Booroola Merino, Border Leicester and Collinsville Merino rams were joined in three successive years to Collinsville ewes and ewe progeny from all three groups were subsequently joined with Dorset Horn rams at Leeton Agricultural Research Station. When data were analysed for performance at up to five joinings and lambings, there were significant differences among the ewe groups in ovulation rat...
متن کاملMilk and Lamb Production of East Friesian-cross Ewes in Northwestern Wisconsin
Two / 2 East Friesian (EF), one / 4 EF, one / 8 EF, and several Dorset rams were mated to crossbred ewes from 1993 through 1996. Growth, reproduction, and lactation performance of their progeny were compared. EF-cross lambs had greater birth, weaning, and postweaning weights than Dorset-cross lambs. When lambing at one and two years of age, EF-cross ewes gave birth to and reared more lambs per ...
متن کاملProduction of yearling Targhee or Finn-Dorset-Targhee ewes managed as a farm or range flock.
Production data from 681 yearling ewes were evaluated for the effect of ewe breed and management system on fertility, prolificacy, lamb birth weight, lamb survival, lamb weaning weight, ewe fleece weight, and total lamb weight weaned per ewe exposed. Two hundred seven straightbred Targhee (T) and 474 1/4 Finn-1/4 Dorset-1/2 Targhee (FDT) crossbred ewes managed in a range or farm flock system we...
متن کاملThe influence of perinatal undernutrition of twin-bearing ewes on milk yields and lamb performance and the effects of postnatal nutrition on live weight gain and carcass composition.
1. Studies were conducted to measure the influence of perinatal undernutrition of twin-bearing ewes on ewe milk yields and lamb performance in early lactation. Comparative studies were conducted with lambs to measure the effects of postnatal nutrition on lamb performance and carcass composition. The major objective of this work was to determine the extent of the influence of postnatal nutrition...
متن کاملEffects of shearing at housing, grass silage feed value and extended grazing herbage allowance on ewe and subsequent lamb performance.
The study involved 120 crossbred ewes (sixty 1.5 years old animals and sixty 2.5 years old animals; initial liveweight 67.6 kg, condition score 3.7), that were mated in October. They were assigned to six treatments (two shearing treatments (shorn and unshorn) × two silage feed values (low and medium) and two extended grazed herbage allowances (1.0 and 1.8 kg dry matter (DM)/day)) designed to ev...
