Impact of prepartum body condition score loss on metabolic status during the transition period and subsequent fertility in Brown Swiss dairy cows

metabolic processes during the transition period to produce good quality colostrum and subsequently milk ( 31 ). Most cows suffer from clinical or subclinical hypocalcaemia during the first days of lactation, and total plasma calcium levels reach their physiological level 2 to 3 days after parturition ( 17 , 32 ). Clinical or subclinical hypocalcaemia negatively affects energy metabolism and the immune status of cows and a variable degree of Ca insufficiency impairs leukocyte activity ( 24 ). The body condition score (BCS) is a useful and simple method to assess an

Use of aVR and Jastrzębski algorithms in the classification of wide complex tachycardia in dogs – a preliminary study

algorithms as well as the VT score developed by Jastrzębski et al . ( 1 , 6 , 7 , 12 ). In veterinary medicine, no such algorithms are available, and the only parameter used for VT description is the duration of the QRS complexes. It is widely accepted that a duration of the QRS complex above 50 ms or 60 ms in large animals indicates a ventricular origin of the tachycardia ( 3 , 11 ). As previously mentioned, such an assumption may be erroneous due to preexisting or temporary interventricular conduction abnormalities, which could present with a similar ventricular

Sensory and ATP derivative-based indicators for assessing the freshness of Atlantic salmon (Salmo salar) and cod (Gadus morhua)

changes, but the latter is the primary determinant of shelf life ( Anacleto et al., 2011 ). The quality index method (QIM) is a scheme used to assess the freshness of fish based on scoring different sensory attributes (appearance, odour and texture) during storage ( Bremner, 1985 ). Assuming the quality index (QI) increases linearly with time, once the total score for fish at the end of their shelf life is established, the score obtained prior to this can be used to estimate the remaining shelf life ( Martinsdóttir et al., 2001 ). A similar approach, quantitative

The impact of cattle drinking points on aquatic macroinvertebrates in streams in south-east Ireland

macroinvertebrates to CDPs, with some sites even showing an increase in abundance and diversity of macroinvertebrates downstream of access points. The objectives of this study were to assess the local-scale impact of CDPs on water quality parameters (i.e. macroinvertebrates and water chemistry metrics) and investigate whether streams with higher water quality scores are more likely to be adversely impacted by cattle access than those with lower water quality scores. It is anticipated that lessons learned from this study will help improve the targeting of future cattle exclusion

Low-density genotype panel for both parentage verification and discovery in a multi-breed sheep population

. An additional one SNP was discarded, which had poor genotype cluster resolution dictated by a GenTrain score <0.55. The GenTrain score is a clustering algorithm propriety to Illumina Inc. and is useful as a measure of the distinction between genotype calls for a given SNP. Berry et al . (2016) evaluated the reproducibility of genotypes from the same SNP locus generated on technical duplicate samples for the same Illumina platform or different Illumina platforms. A total of 1,400 of the remaining SNPs in the present study, reported by Berry et al . (2016) to
