%X <span style=\"font-family:Verdana;\">Agolin</span><sup><span style=\"font-family:Verdana;\">&amp;#174</span></sup><span style=\"font-family:Verdana;\"> Ruminant (Agolin) is </span><span style=\"font-family:Verdana;\">a </span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">blend of essential oils developed to improve feed efficiency while at the
same time reducing rumen enteric methane pro</span><span style=\"font-family:Verdana;\">duction.
Studies have shown that the product improves lactational perfor</span><span style=\"font-family:Verdana;\">mance,
but the range </span></span><span style=\"font-family:Verdana;\">of</span><span style=\"font-family:Verdana;\"> results has been varied. This experiment evaluated the effects of the
feed additive Agolinon milk production in a high</span><span style=\"font-family:Verdana;\">-</span><span style=\"font-family:Verdana;\">component (fat and protein) dairy herd when provided
for an extended time. The experiment was conducted at a large commercial dairy
in the Pacific Northwest</span><span style=\"font-family:Verdana;\">,</span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\"> USA.
Eight </span><span style=\"font-family:Verdana;\">pens of cows (350 to 500 cows/pen) were
blocked by production, and pens</span> <span style=\"font-family:Verdana;\">within
blocks were randomly assigned to treatment. All pens received a</span><span style=\"font-family:Verdana;\"> com</span><span style=\"font-family:Verdana;\">mon total mixed ration. Treatment consisted of
providing 1</span></span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">g/cow/day of</span><span style=\"font-family:Verdana;\"> Agolin
to the test group. A 4</span><span style=\"font-family:Verdana;\">-</span><span style=\"font-family:Verdana;\">week
adaptation period was followed by an 11</span><span style=\"font-family:Verdana;\">-</span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">week </span><span style=\"font-family:Verdana;\">study period.
Milk production and milk composition were determined b</span><span style=\"font-family:Verdana;\">y cow by averaging
daily performance for the one-week period before the start of the trial
(covariate period) and the last week of each of the two test periods. Feed
intakes were determined by pen at the same time. Milk yield was 1.11 kg/cow/day
greater</span></span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:Verdana;\">(P &lt;
0.001) at the midpoint and 1.48 kg/cow/day greater</span><span
