the objective of this study was to evaluate the morphometric and reproductive traits of indigenous dairy goat types. it was conducted in three districts (ebnat, gonji-kolela and farta) based on the agro-ecological differences, goat population potentials and experience of the farmers using goat milk. semi-structured questionnaires, field observations, morphological and reproductive trait measure...

AIM The aim of the study was to assess the effect of udder morphological characteristics on milk yield in zebu cows of Cameroon. MATERIALS AND METHODS The diameter and height of the udder, length and diameter of the teat, and the milk yield were measured in 29 Djafun (Red Mbororo) and 19 Aku (White Fulani) cows in Louggueré zootechnical station in the North region of Cameroon. RESULTS Overa...

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 broken-down, pendulous udder is a defect that occurs frequently among high-producing dairy cows. There are a number of different types of broken-down udders. Some become detached from the body wall, so that the hand can be inserted between the abdomen and the upper surface of the front quarters. Some become elongated vertically like a sack and have a tendency to swing from side to side as t...

It was established by Shaw and Knodt (I) that the normal lactating udder (in situ) of the cow utilizes almost 2 mg. of phydroxybutyric acid per 100 ml. of blood traversing the udder; it was calculated that this was sufficient to account for the short chain fatty acids of milk fat or for about 40 per cent of the oxygen consumption of the secreting gland if it were oxidized for energy purposes. L...

Machine milking efficiency can be summarized as the recuperation of the maximum amount of milk in the shortest amount of time without causing harm to the udder and without any intervention by the milker. This is to say that once the teat cups have been placed on the dairy ewe, the milking machine should be able to quickly remove all of the secreted milk that has accumulated in the udder. Failur...

BACKGROUND:Mastitis is the most economically importantdisease in dairy industry worldwide. Bulk tank milk (BTM)analysis has been suggested for monitoring the udder healthstatus at herd level. OBJECTIVES: A cross-sectional study wasconducted to evaluate udder health status in 15 Holstein dairyfarms located in Qom province. METHODS: Bulk tank somaticcell count (BTMSCC) was analyzed using opto-flu...

the periodic trimming of the long hairs growing at the distal end of the tail -switch trimming- is humane alternative of tail docking. the purpose of this study was to determine the influence of switch trimming on somatic cell count (scc), california mastitis test (cmt) and udder cleanliness of lactating cows in a free-stall dairy farm. in the present study, 219 healthy, pregnant holstein cows ...

A total of 120 quarter milk samples from 30 clinically healthy dromedary camel from Al-Jouf, Saudi Arabia were cultured to detect subclinical udder infection. The milk samples were screened by somatic cell count (SCC) and California mastitis test (CMT). Gram-positive cocci were the dominant recovered udder pathogen. The mean value of SCC was 125,000 cells/ mm. Infected quarter had generally hig...
