Nine gilts with an initial body weight (BW) of 80 kg were fed a diet contaminated with 2 mg/kg deoxynivalenol (DON) and 0.4 mg/kg zearalenone . Their daily weight gain until 100 kg BW was reduced in comparison to the nine control animals fed the uncontaminated diet. The mycotoxins neither influenced the age at the first observed oestrus nor the fertility of the gilts. Multiparous sows received a diet contaminated with 3 mg/kg DON during one lactation period. In comparison to the uncontaminated diet fed to the control animals, more contaminated feed was refused, but the daily intake of 18 mg DON affected neither the weight loss of the sows nor the growth rate of the suckled piglets. Neither the weaning to oestrus interval nor the fertility in the following reproductive cycle was affected by DON.
Stable climate has an important impact on the respiratory health of horses. In a study on indoor climate quality, three different ventilation systems were tested.
Although milk-production oriented (MPO) cow breeds have also become established in the mountain region, farms with the dual-purpose ‘Original Simmental’ breed are proving to be economically viable, with lower costs and higher direct payments making up for lower revenues from milk.
High milk yields before drying-off increase the risk of udder infections during the dry period. An online survey highlights what drying-off methods are currently used and how farmers rate the ‘incomplete milking’ approach for reducing milk yield.
