`The land defines

`
`Labour and soil factors affect
`how this Australian operation is
`set up BY IAN CUMMING
`
`GLENORE GROVE, QUEENSLAND,
`AUSTRALIA - There are only about 20
`farmsin Australia with milking robots,
`from several companies, but dairyman
`Steven Duncanis happy with the three
`Lely units he installed two and a half
`years ago.
`With the booming mining sectorelse-
`where in the country, and youngtal-
`ented people making over $200,000 a
`year,“I couldn't find good labour,” to
`help milk his 180 cows, hesaid.
`He did note that with commodity
`prices crashing, labourwill probably
`come available as long as that situation
`lasts.
`While the robots themselves cost the
`
`same as what a Canadian producer
`would pay, Duncan has them covered
`not by an expensivebarn specially
`designedfor cowflow, but a small, simple
`tin roof with no sides anywhere.
`With the dealer many miles away,a
`local mechanically inclined person has
`become educated on maintenance, but
`it also means they have to carry a higher
`than normal inventory ofparts,said
`Duncan.
`
`Thusfar things have hummed along
`trouble-free with the robots averaging
`2,000 to 2,200kilos per robotper day,
`he said.
`
`Sitting on someof the mostfertile land
`in the country,in this market gardening
`area,the blackrichalluvial soil goes

`
`down for 60 feet and “will turn to mudif
`
`it’s irrigated orit rains,” said Duncan.
`That doesn't makeit ideal for pasturing.
`Twoother roofs have been con-
`
`structedin the past year, giving this
`dairy farm a different appearance from
`the usual one roof overa parlourin this
`country.
`~ Oneroofis over the feed manger,
`where a TMR is fed, and the otheris over
`a compost bedding pack which wasonly
`built last year, said Duncan.
`All areas are connected directly with
`the robots.
`“The bankers were easier to educate
`
`on investing in robots, than the concept
`of cattle housing,” said Duncan. The sim-
`ple housing,with the roofed compost
`pack and covered manger, “made it a
`winner,” as to making the whole system
`work.
`The 160 acres he owns, with the
`majority ofit irrigated, grows enough
`forage for his cows and young stock, but
`he buysin the grain and protein,said
`Duncan.His total feed costs in the TMR,
`whichis fed twice per day, are $7.80 per
`cow perday,he said.
`He averages about36 litres per cow in
`the winter and 32 litres per cow in the
`hot summer. His lowerfat price at just
`under 60 cents perlitre to Parmalat,“is
`break even in the current environment,”
`said Duncan.

`Both winter and summerforageis

`
`grown, mainly a rye grass/alfalfa mixture
`for the winter and sod seeded sorghum
`for the summer. “We get aboutsix cuts
`per year on the rye and four cuts on the
`sorghum forage,” he said.
`Averaging about one tonneofdry
`matter per acre per cut, the 10 harvests
`per year, “means youtravel around that
`field a lot,” he said. The haylage is
`packed into bunks.
`Hefertilizes about 20 poundsof urea
`per acre after every cut.
`Buying the waterforirrigating “is dirt
`cheap"at $9 per megalitre, he said. @

`“When we select a judge for ourfitting

`“He's gotten some ofthe best cowsin

`graduating from Kemptville College.
`And he's now atthe point where “I
`don’t haveto call anyone.If can doit, |
`do.”
`He's clipping 250 days a year and
`making a goodliving.
`“You can't spend three hours ona
`calf” he says. “If you can't get a calf
`done in 45 minutes you're wasting time;
`you're too nit-picky.”
`At World Dairy Expo Hendersonwill
`be doing more thanjust judging the end
`product.
`“Kyle will watch the youth for 60 min-
`utes, make notes and place the topten.
`After the youth are done,hewill give
`them individual pointers on how to
`improve,” says Coyne-DeBruin.
`The youth have one hourto clip and
`prepare their animals, and Henderson
`will be watching how well they know and
`handle their equipmentincluding
`“knowledge of which clippers to use
`where on the body,finished product
`and overall appearance of animal.”
`“Weare looking forward to having
`him as our judge as he workswell with

`great young man.” ®
`
`As his career has propelled him onto

`hasn't abandonedhis central Ontario
`clients. He has beena part of the Web-

`min assessment. They believe that the
`genetic pedigree of today's high pro-
`ducing dairy cowcalls for routine sup-
`plementation, because the modern
`cow’s requirementfor B-vitamins
`exceeds what amounts that rumen
`microbes can normally supply. Hereis
`a brief overview of such positive
`B-vitamin unversity research:
`* PennState fed 6 gramsof supple-
`mental niacin to lactating dairy cows
`fed a typical lactation diets consisting
`of; either corn silage, or corn silage
`and hay, or pasture. The researchers
`found that cows producingat least 35
`kg of milk produced about 2.5 kg
`more milk with supplemental niacin.
`* University of Maryland study, the
`researchers infused choline directly
`into the small intestine of lactating
`dairy cows and successfully exhibited
`a 1.9 kg per head perday increasein
`milk production. The general con-
`science amongstudiesis that a cho-
`line supplement needs to be
`“protected” to bypass the rumen to
`provide any benefit to the animal.
`¢ University of Florida fed mature
`dairy cows O or 20 mg; 16 days pre-
`calving and O or 30 mgofbiotin; 70
`days post-calving. The researchers
`not only found that milk production
`increased about 1.0 kg per head per
`day onthe biotin treatments, but
`these cows had less non-esterified
`fatty acids (NEFA)built upin theirliv-
`ers, whichis a leading causeoffatal
`fatty liver syndromein high perform-
`ing dairy cattle.
`* Ohio State attributed 20 mg of
`supplemental biotin added to the
`transition-early lactation diets
`resulted in 2.9 kg more milk produced
`by biotin-supplemented cows com-

`pared to an un-supplemented control
`CeleReleRPLLia
`group. The control cows averaged
`about 37 kg of milk/day versus about
`40 kg of milk in the biotin-cows.
`Dr. Randy Shaver from University
`of Wisconsin (2000) feed 150-300
`mg per head per day of rumen unpro-
`
`tected thiamine (B1) to lactating
`dairy cowsfed low fiber/high NFC
`diets. The results showed a nominal
`increasein dry matter intake, milk
`production and milk components.
`The biological mechanism for these
`documented positive B-vitamin
`responsesis largely unknown. How-
`ever, many ruminantscientists believe
`that many B-vitamins such asniacin,
`biotin and thiamine act as the “on”
`
`switch of enzymes in the numerous
`intermediary energy-yielding steps,
`which are required to transform
`dietary nutrients into a metabolite
`form that the cows’ tissues can use for
`body maintenance andfor perfor-
`mance such as good milk production.

`ticular enzyme system, like these

`associated with ketosis in early lactat-
`ing dairy cows.
`Since these B-vitaminsare signifi-
`cantly involved in the bio-chemical
`reactions that drive efficient carbohy-
`drate and fat metabolism,it is likely
`that they help drive the biochemical
`reactions that produce more energy
`(glucose) is ultimately available to the
`early lactation cow and thushelp pre-
`vent dangerousketosis.
`A common recommendation is to
`add each of these B-vitamins to a
`
`transition cow diet, which is fed three
`weeks before calving and three weeks
`into early lactation; 6-12 grams of
`niacin per head, or 60 gramsof cho-
`line (in a rumen-protected form), and
`biotin added at 20 mgperhead, daily.
`The respective cost per head per day
`also as follows: niacin @ 8.5-17 cents,
`rumen-protected choline @ 60 cents,
`and biotin @ 3 cents.Lastly, | recom-
`mended adding thiamine @ no more
`
`than 10 cents per head per day to
`help stimulate appetite and dry mat-
`ter intake. One should realize that
`
`there is no substantial proof that add-
`ing any of these B-vitamins together
`yields a cumulative response.
`Nor is there any proof that the gen-
`eral lactating cow population needs
`added B-vitaminsto their overall
`
`dairy diet. Rather, the existing
`research and my own experiencetells
`me that the best areasin the dairy
`barn for B-vitamin supplementation
`is: (1) early lactation cowsin negative
`energy balance, (2) Ist calf lactating
`heifers to stimulate feed intake and
`(3) cowssuffering from significant
`digestive upsets. Otherwise, | formu-

`
`For example, although interdepen-
`dent of one another, these particular
`B-vitamins are strongly advocated by
`the same researchers to be involved in
`
`the regulation of NEFA (non-esteri-
`fied fatty acids) metabolism in the
`liver of early lactation dairy cows.
`Whetherweare feeding health or
`metabolically challenged dairy cows,
`dietary carbohydrates (containing
`glucose) are oftenin short supply for
`early milk production, The dairy cow
`must then burn her own body fat to
`produce immediate energy or non-
`esterified fatty acids (NEFAs), which
`are later transformed back into
`
`energy-rich glucose or provide fatty
`acids for butterfat. However, when
`too many NEFAsare producedfor
`glucose transformation, a good por-
`tion of these NEFAs end up as poison-
`ous ketones.It is these circulating
