studbook information collected from 1988 to 2011 in jafarabad breeding station of moghani sheep, north-west of iran, related to 9,457 lambs were used to study the genetic diversity and to evaluate the effectiveness of an implemented rotational mating scheme using pedigree analysis. lambs born during 2009-2011 were considered as reference population. means inbreeding and average coancestry for t...

In this paper, we study the closed pattern mining problem for a class of spatio-temporal patterns, called closed (k, r)-flock patterns in trajectory databases. A (k, r)-flock pattern (Gudmundsson and van Kreveld, 2006) represents a set of moving objects traveling close each other within radius r during time period of length k. Based on the notion of the envelope for a flock pattern, we introduc...

Changes in anthelmintic resistance over the past 16 years is documented following the isolation of a field strain of Haemonchus contortus in sheep showing multiple anthelmintic resistance at Lawes in south eastern Queensland in 1979. Resistance to thiabendazole was first suspected in 1969 and continued to persist until the present time. In addition resistance to fenbendazole and oxfendazole als...

In this paper, we implement recent theoretical progress of depth-first algorithms for mining flock patterns (Arimura et al., 2013) based on depth-first frequent itemset mining approach, such as Eclat (Zaki, 2000) or LCM (Uno et al., 2004). Flock patterns are a class of spatio-temporal patterns that represent a groups of moving objects close each other in a given time segment (Gudmundsson and va...

one of the traits of the greatest financial impact on sheep production is the number of lambs weaned per ewe with fecb considered as the most well known major gene concerned with this trait. in order to conduct a marker assisted introgression (mai) program the presence of fecb responsible mutation in afshari sheep breeding flock was surveyed. direct test to detect fecbb allele was conducted on ...

A lentivirus has been isolated from a Finnish ewe with ovine progressive pneumonia in a closed upstate New York flock. We demonstrated that the virus, designated ovine lentivirus strain CU1 (OLV-CU1), is biologically, biochemically and molecularly related to, but distinct from, previously described sheep and goat lentiviruses. Nine of 32 ewes (from the affected flock) with precipitating antibod...
