Estimation of Genetic Parameters for Peak Yield, Yield and Persistency Traits in Murciano-Granadina Goats Using Multi-Traits Models [PDF]

open access: yes, 2019
This paper studies parameters of a lactation curve such as peak yield (PY) and persistency (P), which do not conform to the usual selection criteria in the Murciano-Granadina (MG) breed, but are considered to be an alternative to benefit animal welfare ...

On the Persistence of Persistent Identifiers of the Scholarly Web [PDF]

open access: yes, 2020
Scholarly resources, just like any other resources on the web, are subject to reference rot as they frequently disappear or significantly change over time. Digital Object Identifiers (DOIs) are commonplace to persistently identify scholarly resources and have become the de facto standard for citing them. We investigate the notion of persistence of DOIs

Parameters of lactation shape as related to days-in-milk in buffaloes from two different farming systems [PDF]

open access: yesJournal of Central European Agriculture, 2020
Buffaloes from intensive (farm 1 - Fm1; 438 normal, 115 short lactations) and pasture (farm 2 - Fm2; 330 + 58 lactations) system were assigned to study lactation curve via ANOVA (LSMLMW and MIXMDL) per each 10-day period (“tenday”), as well as overall ...

Genetic evaluation for persistency of lactation in Holstein cows using a random regression model

open access: yesGenetics and Molecular Biology, 2007
A model for analyzing test day records including both fixed and random coefficients was applied to the genetic evaluation of first lactation data for Holstein cows. Data comprising 87045 test-day milk yield records from calving between 1997 and 2001 from

Plasmodium malariae: the persisting mysteries of a persistent parasite

open access: yesTrends in Parasitology, 2023
Plasmodium malariae is a 'neglected malaria parasite' in as much as the amount of research conducted on it pales into insignificance when compared to that pertaining to Plasmodium falciparum and Plasmodium vivax, its more notorious and pathogenic cousins.

The persistency evaluation of Czech varieties of Red (Trifolium pratense L.) and Alsike Clover (Trifolium hybridum L.)

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2006
Red clover is the most important forage legume in the Czech Republic. It is an unassuming species to climatic and soil condition, is suitable for mixtures with grasses and it is above other grassland species in forage quality. The most serious problem of
