Javascript ES6 - 204

Aim to type the fewest amount of Unicode characters in your code.

Not the shorter but probably the most obfuscated.

f=(a,b)=>{for(c=[b,a].concat('!,-ADEHIMOWacdefhilmnortvwy \n'.split(o='')),i=62;i;o+=c[e>>10]+c[e/32&31]+c[e&31])e='ⱞᄤ⒇瓤抣瘭㾭癍㚏᫶⦮函࿋Π疽䌐獲樘ྰ㞠戝晐}疽䌐࿈䌐眲Π疽㛏戝癐Π疽伲࿌⒋ფᲉѽ疽䦯䨝抽瘭䦹容㾷碶ᅣᲉᄤྦྷ㜕㞱㗽㾲妴㣗畍⺏'.charCodeAt(--i);alert(o)}

If your browser do not support ES6 :

function f(a,b){for(c=[b,a].concat('!,-ADEHIMOWacdefhilmnortvwy \n'.split(o='')),i=62;i;o+=c[e>>10]+c[e/32&31]+c[e&31])e='ⱞᄤ⒇瓤抣瘭㾭癍㚏᫶⦮函࿋Π疽䌐獲樘ྰ㞠戝晐}疽䌐࿈䌐眲Π疽㛏戝癐Π疽伲࿌⒋ფᲉѽ疽䦯䨝抽瘭䦹容㾷碶ᅣᲉᄤྦྷ㜕㞱㗽㾲妴㣗畍⺏'.charCodeAt(--i);alert(o)}

Copy/Paste that code into your browser console and try f('cow','moo'), f('pig','oink'), f('sheep','baa')

How it works ?

c is an array of 29 letters plus the animal and its sound (let call this our alphabet).
So, all the 31 characters fit in 5 bits (2^5 = 32).
A Unicode character is 16 bits long, so it can encode 3 characters of our alphabet with a padding bit.
The full text with the new lines is 186 characters of our alphabet, it can be encoded with 62 Unicode characters.

For example, Old is encoded like this :

alphabet value         O      l      d
alphabet index         11     20     15
unicode           0  01011  10100  01111  ===> \u2e8f (⺏)

If you have troubles to read some Unicode chars, install Code2000 font

CJam - 142 / GolfScript - 144

{" had| a |farm|68, |68 8|here|Old MacDonald765|, E-I-E-I-O|10,
And on that 5 he7690,
With3 2 and3 t2,
Here4t24everyw23,
10!"'|/~A,{`/\*}/}:F;

Usage: "cow""moo"F
For GolfScript replace '| with "|" and A with 10

Explanation:

The key part is A,{`/\*}/:
A,{...}/ executes the block for each number from 0 to 9 (A=10)
` converts the number to string
/\* does a string replace: if we have on the stack "bar" "foo 1 baz" "1" then / splits the string resulting in ["foo " " baz"], \ swaps this array with the previous item ("bar") and * joins the array resulting in "foo bar baz"

So the code replaces each number in the main string with a string that's previously on the stack. We have the animal and the sound, then " had", " a ", etc and finally ", E-I-E-I-O" and the main string, "10,...!". To avoid using too many quotes, I put all the strings (except the parameters) in one string, then split it and dumped the resulting array ('|/~)

The main string goes through the following transformations:

10,
And on that 5 he7690,
With3 2 and3 t2,
Here4t24everyw23,
10!

replace "0" with ", E-I-E-I-O":

1, E-I-E-I-O,
And on that 5 he769, E-I-E-I-O,
With3 2 and3 t2,
Here4t24everyw23,
1, E-I-E-I-O!

replace "1" with "Old MacDonald765":

Old MacDonald765, E-I-E-I-O,
And on that 5 he769, E-I-E-I-O,
With3 2 and3 t2,
Here4t24everyw23,
Old MacDonald765, E-I-E-I-O!

replace "2" with "here", then "3" with "68 8" etc.

8 corresponds to the sound, and 9 to the animal.

Pure bash, 171 bytes (ascii-only)

I think its worth noting that the original verse (with "cow" and "moo") is only 203 chars.

Alright, this is a bit of a long shot, but who doesn't like over-defining?

StackOverflow is eating my special characters, though, so here's the file in base64:

The data is packed using zlib, which efficiently codes repeated strings (zlib is good at compressing text in general). To take advantage of the "Unicode characters" rule, the 121-byte zlib chunk is padded and halved to a 61-character Unicode string by interpreting the bytestring as UTF-16.

Call the function as

f(cow='pig', moo='oink')

Python, 217

You can't really golf this much. I just took out the blatant front-end repetition and...

m,f="Old MacDonald had a farm, E-I-E-I-O",lambda x,y:m+",\nAnd on that farm he had a %s, E-I-E-I-O,\nWith a %shere and a %sthere,\nHere a %s, there a %s, everywhere a %s %s,\n%s!"%((x,)+((y+' ')*2,)*2+(y,)*4+(m,))

Javascript, 241 - JSCrush cheat

Made this with JSCrush...not really a real answer, it'd just be interesting to see if anybody can beat this in a mainstream language. (EDIT: uh)

Usage: f(new String[]{"cow","moo"});

Java - 262 258

Further optimization is definitely possible.

Perl 5 (UTF-8) - 131 characters, 313 bytes

The script below needs to be saved as UTF-8 with no BOM.

Perl needs to have been run with the -M5.010 flag to enable Perl 5.10 features. (This is allowed.)

I quite like the symmetry of the character count (131) and byte count (313). It's very yin and yang.

Perl 5 (ASCII) - 181 characters, 181 bytes

JavaScript: 152 chars / ES6: 149 chars

Here's a JS function called "z" that does the job in 214 chars. (don't execute it!)

function z(a,b){c=' a '+b;d=c+' '+b;e=', E-I-E-I-O';f='Old MacDonald had a farm'+e;return(f+',\nAnd on that farm he had a '+a+e+',\nWith'+d+' here and'+d+' there,\nHere'+c+', there'+c+', everywhere'+d+',\n'+f+'!')}

I "packed" it in unicode chars using a technique created by @subzey and I for 140byt.es).

eval(unescape(escape('𩡵𫡣𭁩𫱮𘁺𚁡𛁢𚑻𨰽𙰠𨐠𙰫𨠻𩀽𨰫𙰠𙰫𨠻𩐽𙰬𘁅𛑉𛑅𛑉𛑏𙰻𩠽𙱏𫁤𘁍𨑣𡁯𫡡𫁤𘁨𨑤𘁡𘁦𨑲𫐧𚱥𞱲𩑴𭑲𫠨𩠫𙰬𧁮𠑮𩀠𫱮𘁴𪁡𭀠𩡡𬡭𘁨𩐠𪁡𩀠𨐠𙰫𨐫𩐫𙰬𧁮𥱩𭁨𙰫𩀫𙰠𪁥𬡥𘁡𫡤𙰫𩀫𙰠𭁨𩑲𩐬𧁮𢁥𬡥𙰫𨰫𙰬𘁴𪁥𬡥𙰫𨰫𙰬𘁥𭡥𬡹𭱨𩑲𩐧𚱤𚰧𛁜𫠧𚱦𚰧𘐧𚑽').replace(/uD./g,'')))

execute that last snippet, then call z("cow","moo"), and you'll get this string:

Pure C, 298 bytes, no unicode

In my function I take a single argument, which is actually a bunch of char*'s packed together. Each string is null terminated, and there's an extra null terminator at the end. This allows me to check strlen(a) at the end of each loop, rather than keeping a counter variable.

mcdonald.c:

m(char*a){while(strlen(a)){printf("Old MacDonald had a farm, E-I-E-I-O\nAnd on that farm he had a %s, E-I-E-I-O,\nWith a ",a);a+=strlen(a)+1;printf("%s %s here and a %s %s there,\nHere a %s, there a %s, everywhere a %s %s,\nOld MacDonald had a farm, E-I-E-I-O!\n",a,a,a,a,a,a,a,a);a+=strlen(a)+1;}}

main.c:

int m(char *v);
int main(int argc, char **argv) {
    m("cow\0moo\0programmer\0meh\0\0");
    return 0;
}

Output:

clang main.c mcdonald.c && ./a.out

Even for a language with little-to-no multi-lining, and strict indentation rules, Cobra still does pretty well.

C: 224 bytes

By using the printf precision specifier, we can use the same string as both the printf format string and as two of the parameters.

o(char*x,char*y){char*f="Old MacDonald had a farm, E-I-E-I-O,\nAnd on that farm he had a %s%.13sWith a %s %s here and a %s %s there,\nHere a %s, there a %s, everywhere a %s %s,\n%.35s!\n";printf(f,x,f+24,y,y,y,y,y,y,y,y,f);}

With white space and the string split into lines:

o(char* x, char* y)
{
    char* f=
        "Old MacDonald had a farm, E-I-E-I-O,\n"

Old MacDonald had a farm, E-I-E-I-O,
And on that farm he had a mosquito, E-I-E-I-O,
With a zzz zzz here and a zzz zzz there,
Here a zzz, there a zzz, everywhere a zzz zzz,
Old MacDonald had a farm, E-I-E-I-O!
