TIHBM very pleased that my ewes scanned at 210%
TIHBM not so pleased that was just for the flock of 10 zwartbles. The rest scanned at a very disappointing 166%.
Not quite sure where I went wrong there tbh. I kept them maybe a bit tight after weaning, but put them onto good grass 6 weeks before tupping, wormed, fluked and bolused them and even gave them a bit of food to get them to around cs 3.5.
Missed this first time round Si. For commercial sheep, 166% sounds only marginally on the low side to me: much more than that and you'll have lots of triplets, and triplets are dubious economically for general health reasons, extra shepherding care, too much milk demand on the ewes (including more mastitis), and slower growing meaning that they may well need better quality grass or even creep food to finish. The Zwartbles ought to come in with a higher percentage, but as you probably well know, they aren't really commercially competitive except in a niche market.
It's not disastrous but to go from 186% in 2013, 193% in 2014 to this is concerning, particularly as I was so full of hope as they really did have the kitchen sink thrown at them pre tupping - bolus, toxovac, fluke and worm drench and moved onto good grazing. I even gave them a bit of cake as I had let them get a little lean post weaning.
The only two factors I can come up with are that I had them two lean before flushing or maybe because I used one ram per group. 1 in with 68, 1 in with 35, 1 in with 40. In the big group all were marked within the first cycle, 20 or so were marked in the second cycle, 3 were marked in the 3rd.
