There were evaluated 897 Rasa Aragonesa (RA) rams managed as natural breeders which were evaluated.
This increases the number of breeders, which is particularly important in small populations (Pearse and Anderson 2009).
In the present study 13% of the owners of insured dogs were breeders, which is a slightly higher percentage than was found compared to the general dog population (10%; [ 7].
With the exception of territorial breeders (which were considered a special case of closely bonded birds), most ravens did not maintain a given affiliation constellation over the entire study period.
Although Faulkes et al. [ 50] also found relatively low percentage motile spermatozoa in naked mole-rats (< 50%), they reported a significantly lower sperm concentration and lower percentage motile spermatozoa in subordinates relative to breeders, which were not evident from the current study.
For example, one interesting issue is the nutrient profile and restriction level of the diet of breeders, which is tailored to produce the largest possible number of fertile eggs and may thus not fill the requirements for future adult broiler performance [ 151].
This population instability was mainly driven by first-breeders, which are less competitive at breeding sites, being relegated to breed solitarily or in small colony sizes, and disperse farther than adults.
Their compatibility with the liquid breeder, which is in direct contact with the structural alloy, will be essential for reliable and safe operation of the designed blankets.
In the Helium-Cooled-Liquid-Lead (HCLL) design of Test-Blanket-Modules (TBM's) for a future fusion power plant Pb 15.7Li is used as liquid breeder which is in direct contact with the structure material, e.g. EUROFER steel.
"In Denmark, these products were used for breeder hens, which are not in fact marketed," Frédéric Vincent, health and consumer spokesman at the European Commission, said in Brussels in a news briefing broadcast Monday.
This paper presents nuclear performance issues of the HCPB, HCLL, DCLL and WCLL breeder blankets, which are under development within the PPPT Power Plant Physics and Technologyy) programme of EUROfusion, with the objective to assess the potential and suitability of the blankets for the application to DEMO.
