Wool-pulling behaviour appears in a production system with grazing restriction and can be assessed through wool inspection [PDF]
Applied Animal Behaviour Science, 2023 Sheep flocks can be reared in different production systems that differ in the duration of indoor housing and grazing restriction. Indoor housing can lead to aggressive interactions, such as blocking, threats and butts, whereas grazing restriction may ...

The Efficiency of Wool Production
Outlook on Agriculture, 1986 The efficiency of wool production – which in the context of this review means largely the production of fine wool in Australia, the largest grower – depends on local conditions and management systems. The main factors, other than genetic, are climatic and edaphic; the proportion of herbage utilized by the sheep; and the proportion of ingested herbage ...

Effect of temporary weaning and creep feeding on calf growth and the reproductive efficiency of their Hereford dams [PDF]
Animal Bioscience, 2022 Objective The objective was to test if creep feeding (CF) improves the average daily gain (ADG) and weaning weight of calves submitted to temporary weaning (TW) and if the combination of CF and TW improves conception and pregnancy rates of cows.

Impact of adding dietary different levels of protected methionine on wool characteristics, ultrastructure, and blood components of Barki sheep [PDF]
Journal of Animal and Poultry Production, 2021 Twenty-five non-pregnant adult Barki ewes were used to investigate the effect of the addition of various levels of rumen-protected methionine as a feed additive on some wool characteristics, blood components, and wool ultrastructure. Animals were divided

Genetic variation in the ovine KAP22-1 gene and its effect on wool traits in Egyptian sheep [PDF]
Archives Animal Breeding, 2022 The objective of this study was to investigate the genetic polymorphisms in the keratin-associated protein (KAP22-1) gene in Barki (n=206), Rahmani (n=28) and Ossimi (n=28) as the three major sheep breeds in Egypt.

Efficiency of wool production and the mechanics of wool follicle production [PDF]
New Zealand Journal of Agricultural Research, 1979 Abstract The net efficiencies of conversion of feed to wool of Corriedale ewes and rams were determined during a 6‐month feeding trial. Skin biopsy samples were taken at the end of the trial and sectioned transversely. The ratio of area of cross‐section of fibre to area of cross‐section of fibre plus inner root sheath is termed the ...

CORTICAL PATTERN OF COARSE BARKI WOOL FLEECES WITH DIFFERENT COTTING LEVELS [PDF]
Journal of Animal and Poultry Production, 2005 Five adult Barki ewes of each of the four cotting levels: high, medium, low and zero were used. All the experimental animals grazed at Maryout Research Station (35 kilometers south west of Alexandria).

RELATIONSHIP OF CHEMICAL AND SOME PHYSICAL PROPERTIES OF FIBRES IN SHEEP AND GOATS [PDF]
Journal of Animal and Poultry Production, 2002 Wool and hair samples were obtained from fleeces representative of 40 adult animals (20 Barki ewes and 20 Baladi does). Wool and hair samples were divided into two types of fibres, coarse and fine for wool and outer and inner coat for goat hair fibres
