Sorry for the delay, have been a bit busy, I will try to finish the training part today so that for people who need info there is one resource
Nutrition For Dairying ā lets see what I learnt about the feed for the animals
Before we start there is 1 thing we need to note, monocot and dicot ā what is it and difference
Monocot: the cereals which does not break into 2 ā example: maize, bajra, wheat, rice, ragi, milletā¦.
Dicot: cereals which are formed by pairs, easily break into 2 ā example horsegram, cowpea, beans, groundnut and so on
Lets look at some balanced feeding components:
- Water: about 90%; got from drinking water and greenfodder
- Carbohydrates: fodder crops ā monocot (monocot crops are rich in carbohydrates)
- Proteins: Dicot fodder crops, pulses and feed cakes
- Fat: Oil seeds and their cakes
- Vitamins/Minerals: green fodder
- Fibre: Fodder crops ā lack of fibre leads to constipation
Green Fodder:
While cutting the fodder crops, keep in mind that they should be cut during the flowering stage (or just before flowering). Young plants are full of waterā¦ā¦ flowering stage is bestā¦ā¦ yielded plants ā all nutrients are in seeds/fruits
Annual crops: sow once ā cut once then sow seeds againā¦ā¦
Perennial crops: sow once ā cut multiple times
Annual Monocot examples: African tall maize, maize, bajra, oats
Perennial Monocot examples: Guinea grass, Rhodes grass, Co.F.S 29 jowar, napier
Annual Dicot examples: Cowpea. Horsegram, velvet beans
Perennial Dicot examples: Lucerne, Hedge Lucerne, Stylosanthesis
Dray fodder:
Almost same varieties, dried so that about 75% nutrients remain in the crop, water components evaporate.
Concentrate feed:
Monocot: Maize, wheat, rice, bajra, ragi, millet
Dicot: coverings of various grams, groundnut cake, cotton seed cake, coconut cake
The mixture ratio rule is ā 60% monocot + 40% dicot for all variety (green, dry or conc mix)
I was told it is better to milk while you give the conc feed.
Now let us know about calculating the feeding quantity:
Feed is given for 2 reasons
- Body maintainence
- Production of milk
Maintenance approx. ā 1.5 to 2 kgs
Production of milk: 1 kg for producing 2.5ltr milk (in cows)
During pregnancy add 0.5kg upto 6 months and add 1kg from 7th month
Self growth: Add about 0.5kg extra for young cows
I have taken an example for a cow yielding 15ltrs of milk
Milk production only: 8 kgs
a. Maintenance : 2kg
b. Milk production : 6kg (which is 15/2.5)
Pregnant cows: 8kgs as per above calculation plus
a. Add 0.5kg upto 6 months = 8.5kgs
b. Add 1kg from 7th month = 9kgs
Simple formula to calculate: 50% of milk production in a day + pregnant feed + self growth
Which is for 15ltrs a day: 7.5 kgs + preg feed + about 0.5 to 1kg additional
