The loss of dairy calves from stillbirths and disease-related deaths places a significant challenge on the producer who wants farm-specific replacement heifers to maintain or expand herd size. Stillbirths are often overlooked as an important cause of calf mortality, as they are on some dairies. With improved record keeping, data analysis, diagnostic testing and herd monitoring, the appropriate ...

Problem statement: Imported Holstein Friesian dairy cattle are exposed to hot arid climate in feedlot management in Kuwait. Desert climate is extreme reaching high 45-50°C in summer and low -4oC in winter at day and night respectively. High calf mortality, poor reproduction and milk yields were main constraints to viable dairying. The objectives of this study were to assess the magnitude of cal...

A fatal pneumonia due to Legionella pneumophila was diagnosed in a young calf reared in a dairy herd located in northern Italy. Clinical symptoms consisted of watery diarrhea, hyperthermia, anorexia, and severe dyspnea. The pathological and histological findings were very similar to those observed in human legionellosis. Legionella pneumophila serogroup 1 (SG1) and SG10 were isolated from the c...

the objective of this study was to evaluate the effects of weaning age on dry matter intake (dmi), average daily gain (adg), feed efficiency (fe), feed cost (fc) and benefit index (bi) of holstein calves reared under organic farming system. thirty two holstein calves were divided into two treatments: early weaning (ew) vs. late weaning (lw). calves in the both groups were provided with whole mi...

There is growing interest among the public in farm animal welfare and a need for methods to assess animal welfare on farm. A survey on calf rearing practices that might affect dairy calf welfare was performed via a 1-h interview on 115 dairy farms (mean +/- SD: herd size=52.5+/-20.9 cows; milk production=8,697+/-1,153L) distributed throughout the province of Quebec. Despite frequent recommendat...

As a part of ANIPLAN, Norway wanted to look at health and welfare planning for calves in organic dairy production. One reason for this was relevant ongoing activity on calves in Norway. There was also information from earlier projects on welfare assessment (Good animal welfare in organic farming, Animal welfare in Arctic farming) in dairy herds, which showed that calf welfare is a challenge in ...

Pneumonia is the second most common health problem in young calves, after diarrhea. Respiratory infections include all diseases affecting the entire respiratory tract. In contrast, pneumonia is a term that describes inflammation of the lungs only. Pneumonia is a disease that may vary from subclinical to acute and fatal. Depending on the severity of the infection, damage to the lungs can be temp...

The aim of this study was to investigate the effect of different breeds and breed crosses on age (AC, d), BW (kg), price (PR, $/kg), and market value (MV, $/calf) of purebred and crossbred calves sold for veal and beef production. The Kovieh wholesale cattle organization (Bolzano, Italy) grouped calves from several dairy herds located in the Trentino-Südtirol region in Italy and sold them by pu...

this study was done for identification of bacterial agents in calf pneumonia and determination of their antimicrobial susceptibility. bronchoalveolar lavage was done on fourteen pneumonic and seven normal holstein calves between 1-3 month old. in bacteriological examination on the fluid of bronchoalveolar lavage, mycoplasma spp. were isolated from 4 (28.6%) pneumonic calves and 1 (14.3%) health...
