Surgical correction of a double congenital hernia in a veal calf

Veterinary Record Case Reports, Volume 14, Issue 2, May 2026.
Abstract This clinical case report describes the rare occurrence and successful surgical management of two simultaneous congenital hernias, umbilical and perineal, in a crossbred veal calf. At 5 days of age, the animal, weighing approximately 40 kg, showed visible swelling in the umbilical and perineal regions together with a congenital tail ...

The use of computed tomography in a case of septic arthritis and osteomyelitis in a 2‐month‐old Holstein bull calf

Veterinary Record Case Reports, Volume 14, Issue 2, May 2026.
Summary A 2‐month‐old Holstein bull calf presented with a 1‐week history of left front limb lameness. Lameness evaluation demonstrated a Grade 3/5 lameness in the left front limb. Clinical examination revealed resistance to flexion and extension of the left shoulder region, with no associated swelling or joint effusion.

Milk production and survival of spring-calving carryover cows in New Zealand dairy herds : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Animal Science at Massey University, Manawatu, New Zealand [PDF]

, 2017
Non-pregnant cows are generally culled from dairy herds and replaced with two-year-old heifers. Alternatively, non-pregnant cows can be dried-off at the end of lactation, retained for one year (carried over), before being mated and returned to a milking ...

Social rank affects the endocrine response to frequent regroupings in grazing dairy heifers

JDS Communications
The objectives of this study were to determine the social behavior response to repeated social regrouping (SR), and if social rank and the changes of social rank affect the growth rate and some metabolites and hormones linked to energy status, in ...

Diprosopus dirrhinus (nasal duplication) in a female Holstein Friesian calf: Clinical findings, diagnostic imaging and surgical management

Veterinary Record Case Reports, Volume 14, Issue 2, May 2026.
Abstract An 11‐week‐old Holstein Friesian heifer calf presented with a congenital nasal abnormality characterised by an additional, turbinate‐like structure located dorsally on the nasal bridge. Clinical examination of the calf revealed normal respiratory function, with the accessory structure producing mucoid discharge from blind‐ended cavities ...

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 of Age at Conception in Nellore Females Using Threshold Models

Journal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 403-410, May 2026.
ABSTRACT Age at conception is a critical factor in the intensification of production systems. It is crucial for intensifying production, optimising reproductive efficiency and boosting Nellore female productivity for genetic progress. However, the low heritability estimates currently limit the effectiveness of selection responses, thereby underscoring ...
