He said the secret to getting a bobby calf ready for sale a year later was "rain, grass and drench".
The start of spring was "cold and challenging" and featured snow but the weather in November had been warm, rain had fallen, grass had grown and "the cattle had put a lot of weight on".

The second on-farm sale was held at the 400ha Central Park, about 4km further north in Lauder.
A mix of breeds of store steers and heifers were on offer.
After the sale, Central Park owner John O'Brien said the inaugural sale went well and fetched prices he was hoping for.
"No complaints in our corner."
He owned farms in Manawatū and had sales there and decided the time was right to hold a sale on one of his Central Otago properties.

Rural Livestock agent and auctioneer Dennis Mullally, of Alexandra, said the back-to-back sale format was a success.
Demand for store cattle was strong, he said.
Vendors were getting good results and buyers were paying prices allowing a margin to add value before sending them to meat companies, which were paying good prices for beef.
Confidence in the store cattle market had increased since grass had been growing and silage pits were being filled.
Both vendors at the sale presented their cattle in "magnificent order".
