LACTATION CURVE
         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:


      1. INCREASE DRY MATTER COMSUMPTION


      2. INCREASE CONCENTRATES AMOUNT IN FEED


      3. INCREASE ENERGY DENSITY IN THE OVERALL
         RATION OR IN THE CONCENTRATE
                 1) First solution


   To increase the dry matter consumption:

•Disadvantage: During the first two months of lactation the animal’s
                ingestion capacity is limited by:


           - Space occupied by the reproductive system


           - Hormonal change related with calving


           - Adaptation lack of rumen bacteria to new diet
                      2) Second solution

    To increase the proportion of concentrates in the
ration:


* Disadvantage:          Acidosis
            Cereals           Propionic       Rumen pH
                             acid in rumen    decreases


    ↓ % fat milk
                             Ruminal         Lower fibre
    ↓ appetite                                digestion
                            ACIDOSIS
    ↓ production
   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:

      Forage/Concentrates           = 40:60
      Non-fibrous carbohydrates     = 35-40%
                         3) 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
       * 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.

       USE OF

                       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.
                          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
BY – PASS FATS -- MAGNAPAC
       PASS THROUGH RUMEN WITHOUT FLORA ALTERATION


       WHEN REACHED ABOMASUM: BREAKING INTO FATTY ACIDS


       EASY ABSORPTION AT DUODENUM LEVEL




                      RESULT

            INCREASE OF ENERGY SUPPLIED IN DIET

         KEEP THE BACTERIAL PHYSIOLOGY IN RUMEN

    PROVIDE A HEALTHY STATUS TO COW DIGESTIVE TRACT
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.
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
         MAGNAPAC’s energy value
        MAGNAPAC presents an energy value that makes it possible to
adapt the estimated ration:

                                        Magnapac fat content = 84 %

Gross Energy: GE = 840 g/Kg x 9.33 Mcal/Kg = 7.837 Mcal/Kg

                                   Digestibility Coefficient: DC = 90%

Digestible Energy: DE = ME = 7.837 x 0.9 = 7.053 Mcal/Kg

Net Energy of lactation: NEl = 7.053 Mcal/Kg x 0.82 = 5.783 Mcal/Kg

                     UFL = 3.34 UFL/Kg = 24.1 MJ/Kg
                 MAGNAPAC’s 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.

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.
