What is he best known for?
The fields of study he is best known for:
- Statistics
- Genetics
- Animal science
His main research concerns Animal science, Parity, Dairy cattle, Pregnancy and Lactation.
His primary area of study in Animal science is in the field of Herd.
The Parity study combines topics in areas such as Fertility and Heritability.
His research in Dairy cattle tackles topics such as Sire which are related to areas like Age adjustment and Insemination.
P.J. Berger has included themes like Veterinary medicine and Incidence in his Pregnancy study.
As a part of the same scientific family, P.J. Berger mostly works in the field of Lactation, focusing on Reproduction and, on occasion, Breed and Foot rot.
His most cited work include:
- Birth weight as a predictor of calving ease and perinatal mortality in Holstein cattle. (235 citations)
- Genetic and phenotypic parameters for 305-day yield, fertility, and survival in Holsteins. (209 citations)
- Phenotypic trends in incidence of stillbirth for Holsteins in the United States. (196 citations)
What are the main themes of his work throughout his whole career to date?
P.J. Berger mainly investigates Animal science, Sire, Herd, Ice calving and Parity.
His research in Animal science is mostly concerned with Dairy cattle.
His studies deal with areas such as Pregnancy, Insemination, Fertility and Incidence as well as Dairy cattle.
P.J. Berger interconnects Statistics, Artificial insemination, Econometrics and Heritability in the investigation of issues within Sire.
P.J. Berger studied Ice calving and Gynecology that intersect with Luteal phase, Uterine Involution and Physiology.
His Parity research focuses on Age adjustment and how it connects with Scoring system.
He most often published in these fields:
- Animal science (55.22%)
- Sire (35.82%)
- Herd (28.36%)
What were the highlights of his more recent work (between 2002-2011)?
- Genetics (13.43%)
- Quantitative trait locus (10.45%)
- Linkage disequilibrium (8.96%)
In recent papers he was focusing on the following fields of study:
P.J. Berger focuses on Genetics, Quantitative trait locus, Linkage disequilibrium, Sire and Haplotype.
His work investigates the relationship between Linkage disequilibrium and topics such as Family-based QTL mapping that intersect with problems in Genome-wide association study, Genome Scan and Genetic association.
The concepts of his Sire study are interwoven with issues in Biotechnology, Ice calving and Purebred, Crossbreed.
P.J. Berger has researched Haplotype in several fields, including Single-nucleotide polymorphism and Polymorphism.
Animal science covers P.J. Berger research in Dairy cattle.
The Odds ratio study combines topics in areas such as Veterinary medicine, Birth weight, Incidence and Parity.
Between 2002 and 2011, his most popular works were:
- Birth weight as a predictor of calving ease and perinatal mortality in Holstein cattle. (235 citations)
- Factors associated with sow stayability in 6 genotypes. (40 citations)
- A Bayesian threshold-linear model evaluation of perinatal mortality, dystocia, birth weight, and gestation length in a Holstein herd1 (37 citations)
In his most recent research, the most cited papers focused on:
- Statistics
- Genetics
- Internal medicine
Veterinary medicine, Animal science, Parity, Incidence and Birth weight are his primary areas of study.
P.J. Berger studies Veterinary medicine, focusing on Herd in particular.
His research in Herd intersects with topics in Sire, Genetic correlation, Linear model and Ice calving.
His Stepwise regression research incorporates elements of Litter, Weaning weight, Lactation and Weaning.
His work carried out in the field of Gestation brings together such families of science as Odds ratio, Dairy cattle and Odds.
