Data were available for peri-natal lamb survival (PNS), lamb survival from 4 days to weaning (S4DTW), birth weight (BW) and birth coat score (BCS) in South African Merino sheep that were selected divergently from the same base population for their ability to rear multiples. These data spanned the period 1986-2008, and were subjected to genetic analyses involving two three-trait linear-threshold...

Scottish Blackface lamb viability records at birth, and postnatal survival from 1 day to 14 days, from 15 days to 120 days and from 121 days to 180 days were used to determine influential factors and to estimate variance components of lamb survival traits. The binary trait viability at birth was analysed using a linear model whereas the postnatal survival traits were analysed as continuous trai...

We compared the efficacy of combination posaconazole-liposomal amphotericin B (LAmB) therapy to monotherapy with either drug in diabetic ketoacidotic or neutropenic mice with disseminated zygomycosis caused by Rhizopus oryzae. Combination therapy was no better than LAmB alone, and posaconazole monotherapy did not improve survival or reduce fungal burden versus placebo.

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...

The aim of this review is to discuss sensory recognition (olfaction, vision, vocalisation, hearing and direct contact) in relation to the ewe-lamb bond, and the relevance of this information for animal management, considering that sensory recognition between ewes and their offspring is a key element of lamb welfare. In some parental care strategies, parents promote recognition of their own youn...

introduction the mating of related individuals produces an inbred offspring and leads to an increased homozygosity in the progeny, genetic variance decrease within families and increase between families. the ration of homozygosity for individuals was calculated by inbreeding coefficient. inbred individuals may carry two alleles at a locus that are replicated from one gene in the previous genera...

We have compared the activities of liposomal amphotericin B (LAMB) at 3, 5, 10, and 20 mg/kg/day and amphotericin B deoxycholate (AMB) at 1.5 and 2.5 mg/kg/day in a murine systemic infection by Fusarium verticillioides. Survival was improved by all treatments except AMB at 1.5 mg/kg/day. The tissue burden in liver was reduced by LAMB at all dosages and by AMB at 2.5 mg/kg/day. The two highest d...

OBJECTIVES Increased bone marrow iron levels in patients with haematological malignancies is an independent risk factor for developing invasive pulmonary aspergillosis (IPA), suggesting an important role for iron uptake in the pathogenesis of IPA. We sought to determine the potential for combination therapy with the iron chelator deferasirox + liposomal amphotericin B (LAmB) to improve the outc...

data utilized in this study were 6800 records of lambs’ life longevity, and survival rate from 263 sires and 1839 dams collected from 1989 through 2009, from the lori-bakhtiari flock at shooli station in shahrekord. the data were analyzed, using linear and hazard ratio models along with weibul function. these models included such non genetic factors as year and month of birth, sex of lamb, type...
