Beef production from Holstein–Friesian, Norwegian Red×Holstein–Friesian and Jersey×Holstein–Friesian male cattle reared as bulls or steers

Livestock Science, 2015
Abstract The Norwegian Red and Jersey dairy breeds have been evaluated for crossbreeding with Holstein–Friesian dairy cows in Ireland. If such crossbreeding becomes common practice, the resultant male calves will enter the beef industry. The objective was to compare production and carcass traits for Holstein–Friesian (HF), Norwegian Red×Holstein ...

Animal performance and production efficiencies of Holstein-Friesian, Jersey and Jersey × Holstein-Friesian cows throughout lactation

Livestock Science, 2011
The objectives of this study were to examine changes in a number of measures of feed and production efficiency over the course of lactation; to investigate the consistency of breed differences over lactation, to determine the repeatability of each measure over lactation, and to evaluate the impact of the dry period (full lactation cycle) on efficiency ...

Lactation curves of Holstein-Friesian and Holstein-Friesian x Gir cows

Animal Science, 1979
ABSTRACTLinear y = a′ + b′x and gamma type y = ea−cx xb models for the lactation curve (y = daily production on day x of lactation) were adjusted to daily production records of 870 lactations. Within- lactations pooled R2 = 0·71 and R2 = 0·74 were respectively obtained for the linear and gamma type models, the latter being preferred for further ...

Osteogenesis Imperfecta in Holstein‐Friesian Calves

Journal of Veterinary Medicine Series A, 1994
SummaryEight calves with osteogenesis imperfecta were born in a Danish Holstein‐Friesian herd during a two‐year period. In total 92 calves were born (84 normal), and all were sired by a clinically normal Holstein‐Friesian bull. The defect was probably due to a de novo dominant mutation present as a gonadal mosaicism in the bull.

Eisenmenger's complex in a Holstein‐Friesian cow

Australian Veterinary Journal, 2001
A 4.5‐year‐old, Holstein‐Friesian cow presented with a 1‐month history of severe exercise intolerance. Rectal examination and transrectal ultrasonography revealed a large mass in the left retroperitoneum. The heart rate was 70 to 80/min. Premature ventricular complexes and ventricular bigeminy were present on an electrocardiogram.

Cardiomyopathy in Adult Holstein Friesian Cattle in Britain

Journal of Comparative Pathology, 1991
The clinical signs, pathology and breeding data of two cases of cardiomyopathy of an unusual kind in adult Holstein Friesian cattle in Britain are reported and compared with those in similar entities in Switzerland, Japan and Canada. The principal and primary lesions affect the heart and these produce secondary changes, particularly in the liver, and ...

Incidence of Cystic Ovaries in Holstein-Friesian Cows

Journal of the American Veterinary Medical Association, 1974
SUMMARY Cystic ovaries occurred during 42 of 375 (11.2%) calving intervals. Average incidence of cystic ovaries was 5, 16, and 16%, for 1st, 2nd, and 3rd calving intervals, respectively. The incidence of cystic ovaries did not differ significantly between high (10%) and low (12%) levels of milk production or between high (9%) and average (13%) levels ...

Spinal muscular atrophy in Holstein-Friesian calves

Acta Neuropathologica, 1997
The clinical and neuropathological findings of spinal muscular atrophy (SMA) in Holstein-Friesian calves are described in four females and one male from a dairy farm composed of 150 cows and 2 breeding bulls. Locomotion difficulties started at the age of 15 days, and progressed to paraparesis and tetraparesis in 2 weeks.
