BACKGROUND Excessive pregnancy weight gain is associated with obesity in the offspring, but this relationship may be confounded by genetic and other shared influences. We aimed to examine the association of pregnancy weight gain with body mass index (BMI) in the offspring, using a within-family design to minimize confounding. METHODS AND FINDINGS In this population-based cohort study, we matc...

Individual growth and feed intake of 36 Angus, 27 Polled Hereford and 30 Holstein steers were determined from 365 to 560 kg live weight. One-half of the cattle in each breed were fed a diet based on high-moisture ear corn and the other one-half were fed a diet based on corn silage. Within each breed X diet group, half of the cattle were implanted with zeranol. Cattle fed the high-moisture ear c...

Day-old turkeys poults were given a live coccidiosis vaccine via the eye at the hatchery, and all poults produced oocysts in their droppings 7 d later. No oocytes were present in droppings of unvaccinated controls. The weight gain of vaccinated poults challenged at 3 wk of age with a mixture of three species of Eimeria was lower than that of unchallenged poults, indicating that they were suscep...

The effect of lysine dietary concentration (expressed as g of lysine per kg of feed) on growth from 20 to 40 days of age in male broiler flocks was studied by simulating flock performance. A total of 17 sets of parameters was considered. Different hypotheses were made on the means, variances and covariances of initial body weight (20 d of age), live weight gain (20 to 40 d), lipid content of ga...

There is a paucity of data on the beef production potential of Norwegian Red (NOR) compared with 'modern' Holstein-Friesian (HF) cattle. The present study used a total of 64 bulls in a 2 × 2 factorial design study encompassing two breeds (HF and NOR) and two slaughter ages (485; E, and 610; L, days). The mean initial age and live weight of the HF bulls were 179 (s.d. 47.1) days and 203 (s.d. 64...

purpose: obesity is one of the most common problems in the world. imbalance between energy consumption and expenditure is a main factor in weight disorder. exercise helps losing weight by increasing energy expenditure and modulation of the energy intake. the present study examined protective effects of daily moderate aerobic exercise on preventing weight gain in high fat diet rats. materials an...

twenty four primiparous and multiparous holstein cows on early lactation, beginning five weeks postpartum, were used for four weeks to investigate the effects of supplemention of rumen-protected choline (rpc) or vitamin e on milk yield, milk composition, dry matter intake, body condition score and body weight. the cows were randomly assigned to one of the following treatments: i)no supplement (...

Sci., 21: 440–445 Rice bran was added in broiler chicks feed by replacing 20% maize or 15% wheat.
