WHY TO USE ENERGY?
An excessive loss of weight during the first 100
days of lactation gives rise to a series of
problems, of which the following can be
highlighted FALL IN MILK PRODUCTION after
the lactation peak FERTILITY DISORDERS
lowering conception rate High risk of
suffering METABOLIC ILLNESSES (KETOSIS)
NEGATIVE ENERGY BALANCE by high energy
requirements for milk production

POTENTIAL STRATEGIES TO INCREASE ENERGY
CONTENT We shall consider three strategies to
increase the energy consumption

• INCREASE DRY MATTER COMSUMPTION
• INCREASE CONCENTRATES AMOUNT IN FEED
• INCREASE ENERGY DENSITY IN THE OVERALL RATION OR
  IN THE CONCENTRATE

6

• To increase the dry matter consumption
• Disadvantage During the first two months of
  lactation the animals ingestion
  capacity is limited by
• - Space occupied by the reproductive system
• - Hormonal change related with calving
• - Adaptation lack of rumen bacteria to new
  diet

• First solution

7

• To increase the proportion of concentrates in
  the ration
• Disadvantage Acidosis

• Second solution

Propionic acid in rumen
Rumen pH decreases
Cereals
? fat milk ? appetite ? production
Lower fibre digestion
Ruminal ACIDOSIS
8
Consequently, the incorporation of large amounts
of concentrates in the total ration of ruminants
should be limited to 50-60 of the total amount
of dry material, the rest of the food being
forage. Otherwise, we can give rise
to Ruminal acidosis. Reduced
acetic/propionic ratio. Loss of
appetite. Fall in milk production Lower
fat content in milk. Recommendations

• Third solution

• Increase energy density in the overall ration or
  in the concentrate

INCREASING FAT LEVELS IN THE RATION (2.25 times
more energy than cereals) Supply less
cereals in the ration Supply more
forage Maintenance of ruminal pH (6-7) Less
acidosis EQUILIBRATED DEVELOP OF RUMINAL
MICROFLORA Adequate VFA relation in order to
maximise milk production and milk fat percentage
10
Disadvantage - Physical coatin of
fibre - Toxic effect on cellulolytic flora -
Physical coating of microorganisms, reducing the
superficial active enzymes - Reduction
in the absorption of cations
Recommendations In the light of the foregoing,
the NRC (American rationing system) recommends
adding a minimum of fat to the ration, equivalent
to 3 of the total dry substance ingested by a
cow per day (if it eats 21 kg of DS 21x3/100
0.63 kg), but limiting the fat to a maximum of 5
(21x5/100 1.05 kg) in order to avoid a mibrobic
flora unbalance in the belly.

MAGNAPAC
MAGNAPAC, or calcium soap made from palm oil
fatty acids, is the only totally reliable source
of protected fat in the production of feed for
ruminantes. It is an efficient, economic way of
increasing energy intake in dairy cows. There is
no problem with acidosis or fertility. It
helps to maintain high yields and a more balanced
milking curve.
14
MAGNAPAC FATTY ACID CALCIUM SALTS
Normally known as CALCIUM SOAPS These are formed
by saturated and unsaturated fatty acids jointed
to calcium ions to form salts Their protection
mechanism is based on the acidity of the level
where they are found, what is named pH. Magnapac
remains linked in a neutral pH, whereas it is
dissociated in an acid pH. It is made from a
chemical reaction of saponification Fatty
Acid Calcium
SALT

• WHEN REACHED ABOMASUM BREAKING INTO

a) RUMEN When they reach the rumen, the neutral
pH (pH 6.5-6.8) of the medium keeps the salts
united they are insoluble in the ruminal liquid
and, as in the previous case, are not attacked by
the microflora in the belly and do not interrupt
normal activity they are inert or by-pass in the
rumen. b) ABOMASUM On reaching the abomasum,
they encounter an acid pH (pH 2-3) and are
immediately dissociated into calcium and fatty
acids. At this point, calcium soaps lose the
characteristic which makes them inert their
insolubility. As we shall see below, this is of
considerable importance for their absorption in
the intestine.
17
c) SMALL INTESTINE The free fatty acids that
arrive from the abomasum do not need to be
digested in the intestine (as do the saturated
fats). Moreover, the composition of these
products in virtually equal parts of saturated
fatty acids (palmitic and stearic) and
unsaturated fatty acids (oleic) means that the
overall fusion point is nearly 38, resulting in
their union with the gastric juices in the
intestine being carried out with maximum
efficiency. This allows the fatty acids from the
calcium soaps to be absorbed with an efficiency
bordering on 95, avoiding loss of fat in the
faeces and the elimination of cations, which are
so necessary for the animal.

The results of MAGNAPAC
BODY CONDITION It is better as weight loss
decreases MILK PRODUCTION It is higher the
whole production cycle since there is no weight
loss to be recovered 10 mean
increase METABOLIC PROBLEMS Ketosis, Acidosis,
etc. can be easily avoided as no body tissues are
mobilised to fill the milk great requirements and
specially the fat percentage FERTILITY RATE
Higher conception rates are achieved at first
service as consequence of better body
condition FIBER DIGESTIBILITY It allows to
obtain the most of the forage BUTTERFAT
PERCENTAGE As fat content increases at mean two
points

The advantages of MAGNAPAC
SOLID FAT The addition of 50 unsaturated fatty
acid of the supplemented fat does not create any
problem in the ration. EASY HANDLING As a solid
fat, no specific equipmet is required to provide
it. FURTHER STORAGE More than 15 months can be
packed EASY PELLETING No heat is need to add
Magnapac FREE DISTRIBUTION IN FARM Magnapac is
accepted by TMR feeding system RECOMMENDED
DOSAGE 500 G / COW / DAY

MAGNAPACs dosage
The recommended quantities per cow and day vary
according to the production level, the moment of
the lactation period and the presence or absence
of other free supplemented fat in the
ration. The most recommended dosages are -
Medium yielding cows (3000 4000 litres) 250
350 g / cow / day - High yielding cows 350
500 g / cow / day up to 1 Kg The use of the
product is recommended the first 100 days of
lactation, but for its great advantages in
keeping body condition and milk fat percentage,
it should be necessary to use along the whole
cycle.

TRIAL nº 2 Feed Composition
The experiment was developed during first 90
days of lactation. The amount of concentrate feed
was 7.5 kg for both groups. The forage included
15 kg of corn silage, 1.5 kg of alfalfa hay and
10 kg of beer lees.

TRIAL nº 2 Results

• Cows from Test group produced 2.92 litres per day
  more than control group.
• MilK fat increased 0.03 points per litre than
  control group, due to higher amount of
  supplemented fat in the overall ration.
• Milk protein increased 0.02 points per litre
  than control group.
• Body condition kept better in cows supplemented
  with MAGNAPAC, because of no body tissues were
  required to supply fat at mammary gland. Test
  group increased its body weght in 9.5 kg during
  the 90 days of the trial, even they get fatter
  than the initial weight at calving.
