Dairy Cow Nutrition Days Link Feed to Profits
The complexities and myths of understanding dairy cow nutrition and supplements will be unravelled for dairying women
over a series of seminars being held throughout New Zealand in November.
Organised by the Dairy Womens Network, the Dairy Days seminars provide an "insiders" guide to understanding what is
needed to provide cows with well balanced, nutritional diets to optimise their production.
Dairy Womens Network General Manager, Lynda Clark says, "the feedback from women in the Network is that they require a
better understanding of what nutrients are important to dairy performance and what types of feed should be given to cows
during the different phases of the lactation cycle.
"One of the most important objectives of the day is for women to understand how much they can afford to invest in feeds
during each stage of lactation. Optimising your feed budget is just another way to add profit to your bottom line."
The Dairy Days will be led by expert animal nutritionists. Nicki Watt and Carolina Diaz Lira will be speaking at North
Island events, while Andrea Murphy will lead all South Island events.
Animal nutrition expert ad guest speaker, Andrea Murphy, says she has found many farmers have a well founded
understanding of how to grow grass and grass management, but understanding of dairy nutrition as a whole is only
beginning to develop.
Getting to that next level of per cow production means understanding and analysing how a rapidly growing selection of
supplements now available can compliment or supplement the existing grass resource. With this also comes a need to
better understand the workings of the rumen, and how different feeds work within it.
"In Southland, for example, maize silage may not be an option, but whole crop silage, grains or even chocolate waste
from the Cadbury factory may be options."
In addition to brushing up on rumen physiology, the nutritional seminars will provide women dairy farmers with the
opportunity to use all their senses to understand the range of feeds on the market. They will get to see, feel and taste
a large range of feeds and have some of the myths and misconceptions around them removed.
"I think often understanding balanced nutrition is put in the too hard basket. After all, there are already so many
other things farmers must already know."
Yet it may often only be a case of sampling and trialling a supplement that differs to the usual maize silage or, more
recently, the palm kernel option.
The cow's nutrient requirements change throughout the lactation cycle.
"How we feed a cow in the colostrum mob should be different to how we feed a cow in early or late lactation; how we
manage these changes will have significant impacts on production of protein and fat, body condition and reproduction."
The extremely high protein levels of grass in spring time means choosing the right supplement can help reduce the energy
a cow spends excreting that protein as nitrogen.
"For that reason adding in maize silage provides a great balance with its carbohydrate content."
Often it is small, incremental changes to feed inputs that get the results.
"We do not expect all farmers would want, or need to go out, and buy a mixer wagon for example and change their system
wholesale."
Andrea says until recently New Zealand farmers have had the enviable option of simply being able to buy more land to
boost production. However as prices have soared, more farmers will be looking to grow their production from within the
land they already have.
The Dairy Womens Network Dairy Days seminars aim to provide a friendly and not overly technical forum for dairying women
to have questions on nutrition, supplements and rumen workings answered.
"There is a very wide spectrum of women involved in dairying who are keen to learn more. They are often as heavily
involved in these decisions as their partners."
