In the last decades, beef cattle breeding mainly focused on improving production and reproduction traits. Nowadays, there is a growing interest to include behavior and type traits in the breeding goal. There is an interest in behavior as it is associated with human safety and workability and in type traits as they might be associated with longevity of cows. The objective of the current study wa...

Mastitis is a mammary infection caused by the passage of pathogens into the mammary gland. Deteriorations in teat health are shown to be related to this type of infection [1]. Rough or cracked teats allow mastitis pathogens to colonize the udder. Roughness and cracking of the teat is related to hyperkeratosis, the condition of teat end callosity. Rough or cracked teats allow mastitis pathogens ...

A simple method developed and validated by Dr. Pamela Ruegg (Schreiner and Ruegg, 2003) for scoring udder hygiene has proved an invaluable tool to monitor the effect of the cow environment on udder cleanliness. Udder hygiene scores showed a significant association between poor udder hygiene and increasing individual cow linear score and the prevalence of intramammary infection with an environme...

The milking unit can be detached at a milk flow rate of 400 g/min without having a negative effect on milk yield. Machine-on time is shortened and teat condition improved, and udder health does not seem to be affected. The threshold may be set even higher for cows milked more than twice daily. It is recommended that specific setting of switch points and delay times are evaluated for each farm. ...

The study was carried out on a total number of 360 dairy animal, 275 dairy cow and 85 buffalo during the period from Jan. 2010 to March 2015. All the cases were private cases seen in the villages of Damietta and in veterinary convoys held in villages of Upper Egypt. The udder affections included: Deep wounds ( 5(1.4%) , 1(0.28%) ); Heamatoma ( 20(5.6%) ,7(1.9%) ); Abscesses ( 21(5.83%) ,0 ); Ga...

To obtain best results in treatment, an adequate concentration of the drug must be maintained in the udder for a period of time. Best results are usually obtained when the drugs are administered once or twice daily over a period of 2 to 4 days, depending upon the causative agent and the nature of the case. Most staphylococcal infections must be treated longer than streptococcal infections. Clin...

In this article an on-farm monitoring approach on udder health is presented. Monitoring of udder health consists of regular collection and analysis of data and of the regular evaluation of management practices. The ultimate goal is to manage critical control points in udder health management, such as hygiene, body condition, teat ends and treatments, in such a way that results (udder health par...

Udder Injuries often reduces the milk yield and the sustainability of economic returns. Ultrasonography was deployed to study the nature and number of  stulous tract, which developed as a consequence to mid gestational teat injury in afourth parity Jersey crossbred.Teat ultrasonography revealed the discontinuity of teat wall with a singular  stular tract on the lower one third of the left for...

Behavior, type traits, and muscular development are of interest for beef cattle breeding. Genome-wide association studies (GWAS) enable the identification of candidate genes, which enables gene-based selection and provides insight in the genetic architecture of these traits. The objective of the current study was to perform a GWAS for 3 behavior traits, 12 type traits, and muscular development ...
