Heritabilities of milk yield and fat test were estimated from first lactation records of 196,672 Holstein daughterdam pairs separately for registered and nonregistered cows for four milk yield groups and by years of freshening of the daughter. The model included herdseason and sire of the daughter. Heritability estimates were similar for registered and nonregistered cows averaging about .33 for...

The South American Gran Chaco ecoregion extends through great areas of Argentina, Paraguay, Bolivia, and Brazil. region includes vast forests that serve as an important reservoir tropical subtropical diversity. In spite its extent high biodiversity, it remains unexplored area regarding Oribatida. We made bibliographic research about the oribatid mites previously registered. bibliography Argenti...

BACKGROUND Primary biodiversity data records, available on-line, are essential for conservation planning. Of the mega diversity countries, Brazil have reached a high level of scientific research in describing their biodiversity. However, there still remain significant limitations in recovering, collating and organizing available information on Brazil's biological diversity and its distribution....

BACKGROUND Healthcare systems are struggling to deliver high quality care and constrain costs as more people live longer with a greater burden of disease. Providing patients with access to their records and with practice specific health information may improve the quality of care. OBJECTIVE To describe one practice's experience of providing patients with access to their primary care records. ...

The aim of this study was to test the genotypes effect of DGAT1 gene on breeding value in Iranian Holstein milk production traits. For this purpose, 103 semen samples of registered bulls were collected and then genotyped for partial region of DGAT1 gene. The studied traits were milk yield (MY), fat yield (FY), protein yield (PY), fat percentage (FP) and protein percentage (PP). First lactation ...

productive and reproductive traits have great importance in international dairy cattle breeding objectives. production, reproduction (days open and calving interval) and pedigree data of iranian holstein dairy cattles were collected between 2002 and 2012 from 47 herds in isfahan province. the data set consisted of 30179 records from 18837 registered iranianholstein dairy cattles. single trait r...

the variability of temperature and precipitation is regarded as one of the main characteristics of the climate.precipitation and its results, especially results such as droughts, vary on different temporal and spatial scales. thepurpose of this paper is to determine the frequency of the inter-annual variability of the driest month in north-westiran. in order to obtain the best results, we used ...

Mathematical and computational studies of Covid-19 have underestimated the influence that other countries on their daily records. To visualize this, a Granger causality analysis was implemented in Python to determine if cases registered Brazil, Chile, Colombia, Ecuador, Panama, Paraguay, Peru USA any effect Venezuela, between all them. Finally, this paper highlights need incorporate employing o...
