Effects of partial docking on feedlot performance and body fat characteristics were studied in a fat-tailed sheep breed. Thirty-eight male lambs with an average weight of 4.44 ± 0.48 were randomly divided into two groups. The lambs in one group were partially docked at 3-4 h after birth, using rubber rings, and the lambs in another group remained intact (control). After weaning, 20 male lambs f...

20 one-month-old sanjabi suckling lambs (ten males and ten females with initial liveweight of 13.4 ± 1.3 and 11.6 ± 0.9, respectively) were used to assess the effect of ad libitum creep mixture on dry mater intake, live weight gain and carcass characteristics. the lambs were blocked within sex according to their live weight and randomly allocated to one of two treatments, control (free suckling...

forty eight 8-month-old male goats were divided into three groups. in each group, eight goats were feedrestricted for 45, 60 or 75 days, and eight goats served as the control. restricted groups were fed with a maintenance ration, and the control goats were fed with a ration supporting 50 g of daily weight gain. at the end of restriction period, the restricted goats were offered the same ration ...

This contribution describes a new method for monitoring productivity in the slaughter pig production unit. The method is implemented as a stand-alone application, based on data from an existing farmmanagement system. With the new method the amount of information increases from quarterly to weekly estimates of daily gain. By calculating average daily gain each time a group of slaughter pigs is d...

BACKGROUND Primary prevention guidelines focus on risk, often assuming negligible aversion to medication, yet most patients discontinue primary prevention statins within 3 years. We quantify real-world distribution of medication disutility and separately calculate the average utilities for a range of risk strata. METHOD AND RESULTS We randomly sampled 360 members of the general public in Lond...

Holstein calves were fed pelleted starter diets with crude protein (CP) concentrations of 18%, 22% and 24% per dry matter (DM) containing soybean meal (SBM) (SBM18, SBM20 and SBM24), respectively, for 10 weeks from 14 days of age. Another diet with a CP concentration of 18% per DM was tested using commercial xylose-soybean meal (XSB; Yasminomax) instead of SBM. Each diet was fed to 24 calves an...

The dose-response relationship of the ionophore tetronasin was defined in growing-finishing cattle (84 heifers and 84 steers). Cattle were allotted by sex and weight replication (light and heavy) to 24 pens. Six dosages (D) of tetronasin (0, 3.7, 7.3, 11.0, 14.7 and 18.3 mg/kg, dry matter [DM] basis) were fed. Diets containing 40, 25 and 10% roughage were fed for 84, 56 and either 56 (heavy rep...
