READY RECON-ER FOR FEEDING CROSS-BREED CATTLE (HF, JERSEY-400 KG BODY WEIGHT)

TABLE SHOWING READY RECON-ER FOR FEEDING DAIRY CATTLE

Table prepared by Dr PK Shrivastava, on the basis of technical details provided by NIANP, ICAR, Bangalore.


DMI BASED FEEDING REQUIREMENT FOR A DAIRY COW:


Example 1: DMI (dry matter intake) calculation for 400 kg cross breed cow, producing 12 Kg of milk per day

Given: Weight of the cross-bred cow 400 Kg, giving 12 litre milk per day


Ø = As per the 1st thumb rule, 400 kg x 0.025 = 10 Kg Dry matter (DM) should be given to the cow (@2.5% of cow’s body weight)


Ø As per the 2nd thumb rule, divide feed ingredients into roughage (fiber which includes green & dry fodder) and concentrate (Cattle feed (CF), home mixed concentrate feed, which includes grains, brans, oil cakes, salts, etc.).


Ø As per the 3rd thumb rule, an animal need needs 2/3rd fiber and 1/3rd concentrate feed/ CF. = Means 10 Kg DM is divided into 2 parts, 2/3rd (6.60 kg) roughage and 1/3rd (3.30 kg) concentrate. As such, the animal needs 6.60 kg fiber (roughage) and 3.30 kg concentrate feed /CF.


Ø As per the 4th thumb rule, the fiber (green & dry) is given in the ratio of 2:1 (means green fodder 4.4 Kg and dry fodder 2.2 Kg DM). Green fodder contains 75% moisture, so to get 4.4 Kg green dry matter, we must take 17.60 Kg Green fodder (4.4 / 0.25= 17.60 Kg), similarly straw contains 10% moisture, so to get 2.20 dry matter we must take 2.44 Kg dry fodder (2.20 / 0.90 =2.44).


Ø As per the 5th thumb rule, every litre of milk production need 400 grams of CF/ concentrate feed. In this case (12 x 0.4 = 4.80 CF) 4.80 kg cattle feed is required. The dry matter content in the CF is 95% so to get 4.80 kg dry matter from CF, we need to feed 5.05 Kg CF/ concentrate.


Ø Total feeding to this cow would be 17.60 (say 18) Kg Green + 2.44 (say 3) Kg straw + 5.05 (say 5.50) Kg concentrate, total 25.09 (say 26.50) kg (TMR).


Ø In addition to the feed, quality mineral mixture must be fed by mixing into feed, to full fill the deficiency of calcium, other macro and micro nutrients.


Ø If animal is in young and growing stage feed 15% extra ration (over calculation on body weight basis).


Ø If animal is pregnant, 10% extra ration must be given in last trimester of pregnancy.


Example 2: DMI (dry matter intake) calculation for 500 kg cross breed cow, producing 15 Kg of milk per day

Given: Weight of the cross-bred cow 500 Kg, giving 15 litre milk per day


Ø = As per the 1st thumb rule, 500 kg x 0.025 = 12.5 Kg Dry Matter (DM) should be given to the cow (@2.5% of cow’s body weight)


Ø As per the 2nd thumb rule, divide feed ingredients into roughage (Fiber which includes green & dry fodder) and concentrate (Cattle feed (CF), home mixed concentrate feed, which includes grains, brans, oil cakes, salts, etc.).


Ø As per the 3rd thumb rule, an animal need needs 2/3rd fiber and 1/3rd concentrate feed/ CF. = Means 12.50 Kg DM is divided into 2 parts, 2/3rd (8.32 kg) roughage and 1/3rd (4.18 kg) concentrate. As such, the animal needs 8.32 kg fiber (roughage) and 4.18 kg concentrate feed /CF.


Ø As per the 4th thumb rule, the fiber (green & dry) is given in the ratio of 2:1 (means green fodder 5.54 Kg and dry fodder 2.78 Kg). Green fodder contains 75% moisture, so to get 5.54 Kg green dry matter, we must take 22.16 Kg Green fodder (5.54 / 0.25= 22.16 Kg), similarly straw contains 10% moisture, so to get 4.18 dry matter we must take 4.64 Kg dry fodder (4.18 / 0.90 =4.64)


Ø As per the 5th thumb rule, every litre of milk production need 400 grams of CF/ concentrate feed. In this case (15 x 0.4 = 6.00 CF) 6.00 kg cattle feed is required. The dry matter content in the CF is 95%, so to get 6.00 kg dry matter from CF, we need to feed 6.31 Kg CF/ concentrate.


Ø Total feeding to this cow would be 22.16 (say 23) Kg Green + 4.64 (say 5) Kg straw + 6.31 (say 6.50) Kg concentrate, total 33.11 (say 32) kg (TMR=total mixed ration).


Ø In addition to the feed, quality mineral mixture must be fed by mixing into feed, to full fill the deficiency of calcium, other macro and micro nutrients.


Ø If animal is in young and growing stage feed 15% extra ration (over calculation on body weight basis).


Ø If animal is pregnant, 10% extra ration must be given in last trimester of pregnancy.

Good sharing n easy to understand. May kindly account month/ season wise milk variance also.

Calf to Heifer feeding also.

Thanks for your query, that is yet to come in my 4th part of Feeding of Dairy Cattle article. The feeding for calves, heifers (different age group), for pregnant cows (Q1 to Q2, Q3 separate), dry cows, etc.


The seasonal variations as you mentioned, is handled by the farmers /promoters at the local availability of ration at their places in different months.
