Computed Tomography of the Nasal Cavities and Paranasal Sinuses of Cattle at Different Ages

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Computed tomography (CT) provides a detailed, non‐invasive evaluation of the nasal cavities and paranasal sinuses in cattle. Age‐related changes include progressive enlargement of the sinuses and increasing ossification of the nasal turbinates. These findings highlight the importance of considering age when interpreting CT images in bovine diagnostics ...

associated with the darkness of hair coat is found in multiple zebu cattle populations

, 2023
A structural variant (SV) in the agouti signaling protein gene (ASIP), namely ASIP‐SV1, has been found to strongly correlate with the darkness of hair coat in specific regions of the body of bulls from the zebu (Bos indicus) Nellore breed.

Occurrence and Public Health Implications of Brucella Abortus and Antimicrobial Residues in Raw Cow Milk in Bukombe District, Tanzania

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Poor husbandry practices in Bukombe District accelerate diseases in livestock and indiscriminate uses of antimicrobials. Cow abortions, raw cow placenta and aborted fetuses feeding dogs, communal grazing and watering and introduction of new animals predict brucellosis in the herd.

Handmade Biopsy for Genotyping of In Vitro‐Produced Bovine Embryos

Anatomia, Histologia, Embryologia, Volume 55, Issue 3, May 2026.
ABSTRACT Blastocyst biopsy allows genomic selection of pre‐implantation bovine embryos, reducing generation interval and enhancing the genetic gain. We aimed to evaluate the suitability of a simple biopsy procedure, performed by hands, using a splitting microblade and a stereoscope, on in vitro‐produced embryos. Crossbred Bos taurus x B.

Association of immune responses of Zebu and Holstein‐Friesian cattle and resistance to mycobacteria in a BCG challenge model [PDF]

, 2020
Mycobacterium bovis is the main cause of bovine tuberculosis (BTB) in cattle and can also infect humans. Zebu cattle are considered more resistant to some infectious diseases compared with Holstein‐Friesian (HF) cattle, including BTB.

Stayability in the Era of Early‐Challenged Females: Genetic Parameters and Correlations With Economically Relevant Traits

Journal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 422-430, May 2026.
ABSTRACT This study aimed to estimate the variance components, heritabilities and genetic correlations between four new different categories of stayability (STAY48‐2, STAY48‐3, STAY54‐2, STAY54‐3) with weight at 240 days of age (W240), weight at 450 days of age (W450), scrotal circumference at 365 days of age (SC365), age at puberty in males (APM ...

Genetic Parameters for Novel Feedlot Profitability‐Related Traits in Nelore Cattle

Journal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 411-421, May 2026.
ABSTRACT This study aimed to estimate (co)variance components and genetic parameters for accumulated profitability (AFP) and profit per kilogram of liveweight gain (PFT), and their relationships with weight at 450 days of age (W450), scrotal circumference at 365 days of age (SC365), age at first calving (AFC), probability of precocious calving at 30 ...

Impact of Model Parameterisation and Variance Component Estimates on Genomic Predictions of Carcass Traits in Montana Composite Cattle

Journal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 431-442, May 2026.
ABSTRACT This study evaluated the influence of variance component (VC) estimates, obtained from different models and two relationship matrices, pedigree‐based (BLUP) and genomic information‐based (ssGBLUP), on genomic predictions of carcass traits in Montana composite cattle.
