Economic opportunities of using crossbreeding and sexing in Holstein dairy herds.

open access: yesJournal of Dairy Science, 2020
With the increasing availability of sexed semen, farms have the opportunity to select genetically superior dams to produce their replacement animals and to produce crossbred calves for beef production of higher economic value than the remainder of the ...

Conservation of a native dairy cattle breed through terminal crossbreeding with commercial dairy breeds

open access: yes, 2021
Farmers play a key role in conserving native livestock breeds, but without economic support, farms with native breeds may not be viable. We hypothesized that terminal crossbreeding can improve herd economy and decrease the economic support needed from ...

Carcass characteristics of cattle differing in Jersey proportion [PDF]

open access: yes, 2018
peer-reviewedComparison of alternative dairy (cross-)breeding programs requires full appraisals of all revenues and costs, including beef merit. Few studies exist on carcass characteristics of crossbred dairy progeny originating from dairy herds as well ...

Pure-breeding with sexed semen and crossbreeding with semen of double-muscled sires to improve beef production from dairy herds: Factors affecting heifer and cow fertility and the sex ratio.

open access: yesJournal of Dairy Science, 2020
Using sexed semen to produce purebred replacement heifers makes it possible to mate a large proportion of dairy cows to double-muscled sires and to quantitatively and qualitatively improve beef production and increase the income from dairy herds.

Reproductive behavior of Artemiafranciscana (Kellogg, 1906) from San Quintín, Baja California, Mexico

open access: yesCiencias Marinas, 1998
The reproductive behavior of two populations of Artemia is analyzed, one from San Quintín, Baja California, and the other from Yavaros, Sonora. In the interpopulation mating, altemating oviparous and ovoviviparous reproduction was observed, with the ...

Postrelease exploration and stress tolerance of landlocked and anadromous Atlantic salmon and their hybrids

open access: yesConservation Science and Practice, 2023
Threatened fish populations worldwide are relying on stock supplementation by hatchery‐reared fish. Although stocking with non‐native fish may lead to hybridization, thereby disrupting local adaptations, it could also improve the adaptive potential of ...

Resilience effects of SGK1 and TAP1 DNA markers during PRRSV outbreaks in reproductive sows [PDF]

open access: yes, 2020
The porcine reproductive and respiratory syndrome virus (PRRSV) is a major infectious stressor that causes serious health problems and productivity drops. Based on previous genome-wide analyses, we selected SGK1 and TAP1 as candidate genes for resilience,
