I have a loan of an old ram (I think he's 7 next Feb) He has only had 4 ewes to tup. Three have not come back in season so are hopefully in-lamb. He is on good grass and has been getting fed sheep mix every day but he is definitely needing more weight on. Been wormed for fluke and other worms. He's eating the mix with no problems so presume his back teeth are ok. He is bright and seems quite happy in himself Is it the case that he is of an age where it is difficult to get weight on him? Any suggestions for improving his lot? Will be getting the vet out to look at one of my other sheep so will obviously ask him but am interested in any comments from experienced sheep keepers out there, thanks
