Application of Genomic Random Regression Models for Genetic Parameter Estimations of Female Fertility Traits in Different Parities in German Holsteins

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The aim of the present study was to infer genetic (co) variance components and to estimate parity‐specific breeding values for the female fertility traits non‐return rate after 56 days, the interval from calving to first service and days open by applying random regression models on a time‐dependent parity scale. In this regard, we considered a

Genetic Evaluation of Beef Sires Using a Beef‐on‐Dairy Crossbred Reference Population

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In recent years, Beef‐on‐Dairy (BoD) crossbreeding programs have gained momentum to enhance dairy cattle's economic and genetic merits while meeting the demand for high‐quality beef. However, bulls with superior growth potential can lead to calving problems; thus, Holstein dairy farmers must decide which semen to use to avoid calving problems ...

Daśaratha’s Horse Sacrifice in the Rāmāyaṇa

open access: yesOrientalia Suecana, 2020
This article discusses Daśaratha’s horse sacrifice at 1.8–16 in Vālmīki’s Rāmāyaṇa. Daśaratha’s rite seems to be a horse sacrifice, then a son-producing rite, then a porridge-eating rite.

Genomic Analysis of Inbreeding Depression on Productive Traits in Rubia Galega Beef Cattle Breed

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In autochthonous livestock breeds with small populations, such as the Rubia Galega from Galicia (Spain), mating between relatives is common and can lead to inbreeding depression. Genomic inbreeding coefficients were estimated for 4984 animals using ~63,000 SNPs to assess inbreeding depression in four key traits: age at first calving (AFC) with
