This paper describes a cost effective Wireless Sensor Network (WSN) technology for monitoring the health of dairy cows. By monitoring and understanding the cow individual and herd behaviour, farmers can potentially identify the onset of illness, lameness or other undesirable health conditions. However, the WSN implementation needs to cope with various technical challenges before it can be suita...

Background: Cryptosporidium is one of the most important agents of food-borne diseases with gastrointestinal symptoms such as diarrhea in either livestock or humans. This protozoon can be transmitted to human through consuming contaminated raw milk and dairy products. The present study aimed to detect Cryptosporidium spp. in traditional raw cow milk, cream, and cheese consumed in Yazd city, Cen...

Milking data of 34 single automatic milking system (AMS) units on 29 Galician dairy farms were analyzed to determine the system capacity in each farm under actual working conditions. Number of cows, milk yield, milkings per cow per day, actual milking time, rejected milking time, cleaning time, and machine downtime were used to determine the number of cows milked per AMS unit to obtain the opti...

Prostate cancer (PCa) is dependent on androgen receptor signaling and aberrations of the PI3K-Akt-mTORC1 pathway mediating excessive and sustained growth signaling. The nutrient-sensitive kinase mTORC1 is upregulated in nearly 100% of advanced human PCas. Oncogenic mTORC1 signaling activates key subsets of mRNAs that cooperate in distinct steps of PCa initiation and progression. Epidemiological...

the study was carried out for a period of 150 days on 120 holstein friesian crossbred dairy cows between mid to late lactation to quantify the influence of body condition score (bcs) on yield and composition of milk. total 12 dairy farms having same housing systems and holding at least 20 crossbred dairy cows per farm between mid to late lactation were selected for this study purposes. bcs of i...

this study investigated the effect of rumex sc (commercial product which includes of saccharomyces cervisiae, saponin and essential oils) on rumen fermentation, blood glucose, urea, milk yield and milk composition. animals were offered a basal diet containing alfalfa hay (15.5%), corn silage (24%), beet pulp (7%) and concentrate (53.5%). additionally, rumex sc was included in the experimental d...

the aim of this study was to evaluate the effects of balancing low protein diets for methionine and lysine on performance of early lactation holstein cows under hot environmental temperature. twenty one multiparous holstein cows in early lactation were allocated to three experimental rations including, 1) high protein ration with 17.5% cp, 2) medium protein ration with 16% cp and 12 g/d rumen p...

Mastitis is inflammation of parenchyma of the mammary gland regardless of the causative agent. The objective of this study was to determine the prevalence, risk factors and financial losses caused by mastitis in six small holder dairy farms and the Animal Production and Research Center of the Wollega University. Data was collected through a questionaire on extrinsic and intrinsic risk factors a...

Studying out isochronous and automatic project about three-dimensional imaging system of dairy cow forming by computer, CCD video camera, frame grabber, photoelectric switch, SCM, automatic door, electric barrier etc. SCM detects signal of photoelectric switch, and it makes sure info of the orientation of dairy cow. Computer control frame grabber to grab image. The dynamic link libraries techno...

Bovine abortion is an important cause of economic loss to the cattle livestock industry. In California this may as much as $700 for each cow that has aborted (Thurmond & Picanso, 1990). Kossaibati & Esslemont (1997) estimated the average cost of calf mortality in English dairy herds was £310 per calf death at 1995 prices; for culling an additional cow following illness, such as abortion, it was...
