Effects of Feeding Buckets Number Per Pen on Performance and Behaviour Indicators of Lambs

Twenty-four 35-day-old lambs were distributed to a completely randomized design with 3 treatments to study the effects of number of feeding buckets per pen on performance, haematology and behaviour indicators. Treatments consisted of 8 (T1), 4 (T2) or 2 (T3) feeding buckets/pen (8 lambs/pen). During the experiment, concentrate was fed at 08:30 in individual feeders. Daily dry matter intake (DMI) and average daily gain (ADG) were recorded weekly. Blood samples were taken from all lambs at the time that animal allocated to experimental diet and at the end of the first, second, third, fourth, fifth and sixth weeks and analyzed for haematological parameters. Maintenance and social behaviours were registered based on the methods of scan sampling. Decreasing number of feeding buckets per pen resulted to low overall DMI and ADG (P
