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 ...

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...

Absract: Reproductive health problems are one of the most important problems that affect the production and productivity of dairy cows. Dystocia is also one of the reproductive health problems that cause considerable economic loss to the dairy industry. The main aims of this manuscript were to review risk factors and economic impact of dystocia in dairy cows. Dystocia is also defined as prolong...

The tropics is not an ideal location for calf rearing as the high temperatures and humidities introduce many potential disease problems to milk fed calves. In addition, the type of dairy farming (generally poorly resourced small holder farming) and the general lack of awareness of the long term implications of poorly reared stock do not encourage farmers to pay close attention to their calf and...

Dairy calves are extremely susceptible to gastro-intestinal disease during the pre-weaned period. The risk for enteric disease decreases as the calf ages; therefore, it is important to break the pre-weaned period up into at least two distinct phases that likely need to be managed differently, early life (first couple weeks of life) and the remaining time the calf is fed milk or milk replacer. W...

A prospective cohort study was undertaken on two central California dairies, A and B, to estimate prevalence of congenital infection with Neospora caninum, to characterize temporal variation in prevalence, to determine if occurrence of congenital infection was associated with specific dam and calf attributes, and to estimate the effect of congenital infection on calfhood mortality. Of the 405 c...
