'dealt with'? lol. Your idiotic troll-fest(er)s are fooling nobody.
Let's see boil provide evidence to support his 95% feedlot
beef gain (on liveweight yet). <chortle>
************************************************** *****
Data and calculations-- feed : beef ..
Live-weight 900 1040 1146 1258 1403 lb
'harvest' 1 ..... 2 .... 3 .... 4 ...... 5
Fat % 17.7 ........22.6 ..... 28.1 .......30.3 ..........34.0
Protein % 14.5 ........13.9 .......12.6 ......12.0 ..........11.6
Water % 51.3 ...... 48.0....... 43.9 ...... 42.3.......... 40.1
Bone % 16.4 ....... 15.4 ...... 15.4 ...... 15.3 .........14.3
carcass weight 450 550 650 750 850 lbs.

(protein + water = meat)
(1) 65.8% of 450lbs carcass, (4) 54.3% of 750lbs carcass.
= 296.1 = 407.25
-- a gain of 111.15lbs of meat for + 300lbs of carcass weight-
37.0% of carcass gain.
(1) 73.8lbs of carcass bone, (4) 114.75lbs - an increase
of 40.95lbs for a 300 lbs increase in carcass weight-
13.65% of carcass gain.
(1) 79.65lbs of carcass fat, (4) 227.25lbs of fat- an increase
of 147.6 lbs of fat for a 300lb increase in carcass-
49.2% of carcass gain.
That is just the (4) 62% dressing percentage (carcass).
Looking at the figures we can find out how much of the total
live-weight gain was not carcass.
1) 900; ..............and 4) 1258 lb (-live weight)
1) - 450; ..............and 4) - 750 lbs. (-carcass)
= 450 = 508
508 - 450 = 58 lbs increase in wastage (viscera, fat, etc).
Total increase; carcass + wastage -- 300 + 58 = 358lbs.
Meat gain- % of total high-concentrate ration live-weight gain;
111.15/358 * 100 = 31% .
----------------------------------------------------------
Add 10% of that 31% for fat content = 34.1 % beef gain.
----------------------------------------------------------
[Round to 34].
['... An 800-pound, medium-frame steer calf will eat about
16.8 pounds of dry matter a day of a high-concentrate ration.
He will gain about 3.0 pounds a day with daily nutrients in his
feed at the level shown here.
The balanced daily ration for the 800-pound yearling steer is:
Pounds
Corn 14.7
Soybean meal 0.52
Corn silage 10.00
Limestone 0.17
Total 25.83

feed: meat (without fat);
31% of 3lbs (48oz) = 14.88oz total edible meat
(minus fat content) from 3lbs live weight gain.
25.83lbs = 413.28oz.
------------------------------------------------
413.28 feed / 14.88 meat (no fat) = 27.77 : 1.
------------------------------------------------
[round to 28]
'When an animal makes 20 grams of meat protein,
it adds them to 80 grams of water to make meat.'
http://www.aps.uoguelph.ca/~swatland/ch2_4.htm
-80% water content -
14.88 * 20% = 2.97oz (meat protein (DM) from 3lbs live-weight).
1lb = 16oz. 16.8lbs * 16 = 268.8oz
----------------------------------------------------------------
268 feed (DM) / 2.97 meat protein (DM/no fat) = 90.23 : 1 .
----------------------------------------------------------------
[Round to 90]
All trimmed beef (with the exception of short ribs)
contains up to 10% fat..
'Which beef cuts are the leanest?
All trimmed beef cuts, with the exception of short ribs,
meet Health Canada's definition of "lean" meat. This means,
all these beef cuts contain no more than 10% fat. In fact,
many trimmed beef cuts qualify as "extra lean", with 7.5%
fat or less. Cuts from the hip, such as round steak/roasts,
sirloin tip, are usually the leanest choices.'
http://www.beefinfo.org/nut_faq.cfm.
'Ground beef, whether it comes from the chuck or the round,
is of equal quality. The only difference lies in the amount of
fat in the product -- the more fat, the less the value.
Common ground beef percentages (and the terms
often associated with them) a
70 percent lean, 30 percent fat (ground beef)
80 percent lean, 20 percent fat (ground chuck)
85 percent lean, 15 percent fat (ground round)
90 percent lean, 10 percent fat (ground sirloin)
...
The price goes up with each decrease in fat content, so
ground beef (70-30) is the logical choice if price is the
most important factor. But fat cooks out of ground beef,
resulting in greater shrinkage. The higher fat content also
makes it a poor choice for those concerned about fat
and calories in their diet.
At the other end of the spectrum, the ground sirloin (90-10)
will be the most expensive, and because of the small amount
of fat, it might be dry, crumbly and tasteless. But, for the
health-conscious, it may be just what the doctor ordered.
http://www.dispatch.com/news/food/fo...17/282614.html.
As we can see from the agricultural research data, the
percentage of lean decreases -(1) 65.8%, (4) 54.3%
of carcass weight, with increase in fat (1)17.7, (4)30.3,
whilst bone and viscera, etc, also continue to develop.
The net amount of gain of meat protein + water (meat)
is only 31% of the total (4) live weight feedlot increase.
Add to that 10% of that 31% for fat content to give
you 34% beef gain.
The ratio for feed : beef inc.10% fat;
34% beef gain (inc.10% fat) of 3lbs live weight gain =
48 * 34% = 16.32oz
25.83lbs * 16 = 413.28oz
------------------------------------------------
413.28oz of feed / 16.32 oz beef = 25.32 : 1
------------------------------------------------
[Round to 25]
Adding the beef's 10% fat content to the 31%
meat protein (DM) of 3lbs of live weight gain;
3lbs = 48oz. 48 * 31% = 14.88
14.88 * 10% = 1.49 fat
(for every 20 grams of triglyceride, it can only add 1
gram of water to make fat)
1.49 oz fat / 21 = 0.07oz water (-) = 1.42oz fat (DM).
1.42oz fat (DM) + 2.97oz meat protein (14.88*20%)
= 4.39oz beef (DM/inc. fat)
feed (DM) -16.8lbs * 16 = 268.8oz
--------------------------------------------------------
268.8 feed (DM) / 4.39 beef (DM/inc.fat) = 61.23 : 1
--------------------------------------------------------
[round to 61]
So;
==========================================
The ratio of feed to beef (inc. fat) is 25 : 1.
The ratio of feed to meat (minus fat content) is 28 : 1.
The ratio of feed (DM) to beef (DM/inc.fat) is 61 : 1.
The ratio of feed (DM) to meat protein (DM/no fat) is 90 : 1.
