One possibility is that this linguistic sleight of hand occurred because of the association between a magpie's characteristic black and white plumage, and the appearance of medieval pies. And the cook who joined Geoffrey Chaucer's pilgrims headed for Canterbury, "koude rooste, and sethe, and broille, and frye,/ Maken mortreux, and wel bake a pye" in the Canterbury Tales. The dictionary references a Rogero Pyman selling pies in 1301. īut it's not long before the word pie starts to turn up with its edible meaning. ![]() These chattering pies first show up in English manuscripts in the 13 th century, along with their close relatives crows, rooks and ravens. Before that they were called simply "pies" or "pyes," the original Latin having been shortened and smoothed as it made its way through older versions of French and English. Magpies didn't actually acquire the prefix mag- until the 17 th century. So how do you get from a smart Roman bird to the traditional Thanksgiving dessert? The OED admits it's all bit uncertain, but offers a few linguistic clues to how these black and white birds could have been transformed into edible pies. That's because, according to the Oxford English Dictionary, the word "pie" - defined as a baked dish topped with and sometimes also surrounded by pastry - may well derive from the Latin word pica, meaning magpie. But when it comes to dessert, it's worth considering the relevance of another bird - the humble magpie. This is the month when the stately, voluptuous turkey takes a place of pride on most dinner tables. Poor growth rates also mean cows are grazing lower than normal grass covers, which are low in fibre – a complicating factor.A drawing of a medieval pie baker, circa 1465-1475. Purple tips on grass can indicate low phosphorus levels. This is because grass growth has been poor, leading to poor uptakes of phosphorus from the soil (grass is the main source of phosphorus in the diet). Generally, this time of year is when pica symptoms are most likely to appear and the cold weather over the last few weeks has increased the risk. It can be associated with a lack of fibre in the diet and also a salt deficiency. Phosphorus is an important element so any deficiency should be taken seriously, particularly during the breeding season. The most obvious symptom is cows chewing on stones, plastic or wire. The last 10 days or so have seen a big increase in dairy herds showing signs of pica, or phosphorus deficiency. The one-size-fits-all approach is flawed. Typically, the summer months are when most drainage is done – make sure and dig a test pit and get some expert advice before undertaking a project. ![]() Improving soil fertility, breeding high-EBI cows and maintaining high levels of ryegrass in the sward deliver the return on investment from drainage and grazing infrastructure. It’s not simple and there are challenges. The participants in the programme are getting very good performance on marginal land. This week we take a look at some lessons from the heavy soils programme. Ideally, you’d like average farm cover to be around 160kg to 180kg/cow around now. In some cases the supplement will have to stay in until average farm cover goes back to target levels. The best policy is to walk the farm every few days and make decisions then. Most farmers are feeding more meal than normal, and as growth rates pick up there is an opportunity to cut back on supplement. Soil temperatures have increased over the past week and the outlook for grass growth is good, with most counties predicted to grow over 80kg/day this week. Check inclusion rates of P when comparing products. Adding P to the water is more expensive at around 10c/cow/day but is said to be more available so recovery is quicker. If a cow was consuming 10g of phosphorus per day, it would cost 2c/cow/day. High-phosphorus mineral blocks cost about €30 for a 15kg block. Increasing the fibre content of the diet might be necessary in some cases too, by feeding small amounts of hay, straw or silage.Ĭost wise, adding phosphorus to the meal costs about €15/t to €20/t extra, which works out at 3c to 4c/cow/day if on 2kg of meal per day. Some find that giving cows access to salt licks helps also. It usually takes a week to 10 days for symptoms to disappear after the supplement is added. The usual course of action is to supplement with phosphorus either through adding it to the water, through meal or through mineral licks. However, it can affect performance so it should be treated quickly if it appears. The first thing to say is that it is usually transient and will correct itself in a matter of time. ![]()
