For Breeding. I would guess they weigh around 450+.

Thanks,

Devon

Thanks,

Devon

Devon ---I assume these calves just weaned and I hope they are now weighing at least 450 lbs. I dont know what kind of cattle you have but an avg cow weighing in at 1200 should at least be able to wean a heifer calf at 450#. That being said, normally you want to grow out a heifer where she will weigh 65% of mature weight at breeding. So if her mature weight is 1100 you want her to weigh in the 700's at breeding. I go by weight, but also prefer she be at least 15 months at breeding that way it is easier to record her progress over the years as she should have a calf per year at age 2,3,4,5,6,7,8...... etcFutureFarmer":30j2ckg6 said:

710 lbs at 15 months (breeding) - 450 lb heifer at 7 months = 260 lb gain in 8 months (avg = 33 lbs/mo)

a heifer weighing in at 450 needs 1.3 lbs of total protien per day to gain no more than 1.1 lbs per day (33+ lbs per month)

That being said, I would recommend the following:

a 12- 13 % ration with corn (energy is required) (240 to 260 lbs TP per ton) This isn't rocket science

Corn 800 lbs per ton @ 9% CP = 72 lbs TP

Soybean Hulls 600 lbs per ton @ 12% = 72 lbs TP

Soybean meal 250 lbs per ton @ 44% = 110 lbs TP

300 lbs of coarse grass hay per ton @ 5% =

50+ lb of all purpose mineral per ton = 260 lbs TP or ~ 13% feed ration

You must start them out slowly (Dun was right about that part only) and I would feed them 3 lbs to start for a few days

Should take about a week to get them on a full ration. 3 lbs of 13% x .90 TDN = 0.35 lbs TP + free choice grass hay@ 12%

Every few days up their feed until you get to 5 lbs of feed per day of the 13% ration--say by the 7th day. Clean water is also a must.

450 lb heifer post-weaning; post back-grounding;

Month 1, should be getting 5 lbs of 13% ration + free choice 12% grass hay

Month 1 (450 lb heifers) (

5 lbs of 13% FEED = 0.65 lbs TP and 8 lbs of grass hay @ 12 % CP and 50 % TDN = 0.48 lbs of TP which =

Month 2 (485 lb heifers) (1.10 TP) adjust feed accordingly and do your own math

Month 3 (520 lb heifers) (1.35 TP) adjust feed accordingly and do your own math

Month 4 (555 lb heifers) (1.40 TP) adjust feed accordingly and do your own math

Month 5 (590 lb heifers) (1.40 TP) adjust feed accordingly and do your own math

Month 6 (625 lb heifers) (1.50 TP) adjust feed accordingly and do your own math

Month 7 (660 lb heifers) (1.50 TP) adjust feed accordingly and do your own math

Month 8 (705 lb heifers) (1.55 TP) adjust feed accordingly and do your own math

or say you had 10 weaned heifers to grow out you could plant 5 acres of Rye @ 2.5 to 3 bu. per acre and graze them on it for about 2.5 hours per day then offer them free choice hay, which can be low quality for filler, and call it a day, then spend your excess cash money on a new deer rifle.

That's It!

a heifer weighing in at 450 needs 1.3 lbs of total protien per day to gain no more than 1.1 lbs per day (33+ lbs per month)

"(Duns' ration, for example: 16 % ration at 1.5 lbs per day would yeild a Total protein of <0.22 lbs of Total protein which is really wrong)" don't do that, because even to maintain an animal weighing in at 450# requires at least 0.7 lbs TP per day

That being said, I would recommend the following:

a 12- 13 % ration with corn (energy is required) (240 to 260 lbs TP per ton) This isn't rocket science

Corn 800 lbs per ton @ 9% CP = 72 lbs TP

300 lbs of coarse grass hay per ton @ 5% =7 lbs TP

50+ lb of all purpose mineral per ton = 260 lbs TP or ~ 13% feed ration

Remember a 450 lb calf can only eat about 2.8% of its' body weight (BWt) per day which is 13+ lbs of something per day

You must start them out slowly (Dun was right about that part only) and I would feed them 3 lbs to start for a few days

Should take about a week to get them on a full ration. 3 lbs of 13% x .90 TDN = 0.35 lbs TP + free choice grass hay@ 12%

450 lb heifer post-weaning; post back-grounding;

Month 1, should be getting 5 lbs of 13% ration + free choice 12% grass hay(whatever you do in the feeding realm, remember that your heifers are still ruminant animals and they need at least 20% of their diet to be in the form of a forage)(this is why I always incorporate coarse grass hay into my feed rations to keep the rumen active)

Post Weaning

Month 1 (450 lb heifers) (1.10 TP)

5 lbs of 13% FEED = 0.65 lbs TP and 8 lbs of grass hay @ 12 % CP and 50 % TDN = 0.48 lbs of TP which =1.13 lbsTP per day, which will meet their requirements.

With decent hay, not junk, if they can;t grow out on that ration they really don;t need to be kept as breeders. We don;t feed grain except during the weaning phase, after that it's hay or stockpiled pasture.

Bull, you're probably right. I guess I probably forgot to figure the good high TDN of that 5% hay into the mix. I'll sit back and wait for the expert to show me exactly where I'm wrong, but it appears he's not using NRC standards. :lol:

Now this is interesting.

Seems that on another thread you were ranting and raving about how stupid it was to feed hay.

Seems that you were going to be totally independent from hay.

I wonder who's looking stupid now.....

Keep working on them people skills 4CT. Maybe one day, you can be as good with them as your are them cattle skills that you so proclaim to the world.

Granny..shame shame...you wuzn't suppose to see or remember that post. :lol:

Also you're skipping some steps in your calculations. Rework your paper and turn it in tomorrow with realistic numbers using NRC standards. :dunce: :dunce: :dunce:
