Feeding preferences in lambs influenced by prenatal flavour exposure.

The aim of the present study is to highlight and evaluate the role of flavour prenatal exposure in postnatal feeding preferences in sheep after weaning and until the early stages of puberty. 16 lambs were selected from two groups of ewes; the first group was fed with a control diet, consisted of concentrated feed and alfalfa hay and the second group with the same diet, with the only difference that the concentrate was supplemented with oregano essential oil (1 ml/kg), during the period of pregnancy (50th-130th day). Lambs were later individually subjected to feeding preference tests, at the age of 3, 4.

Effect of breed and age on sexual behaviour of rams.

The objective of this study was to highlight the problems that arise during the reproduction between thin-tailed rams and fat-tailed ewes. At the same time, particular emphasis laid on the influence of sheep breed, sheep age, time after ram introduction and day of the ewe estrus cycle on ram and ewe sexual behaviour. Rams were subjected to sexual performance tests by being individually exposed to 12 ewes for 3 h daily, 19 consecutive days.
