ENHANCED MILK PRODUCTION EFFIENCIENCY IN DAIRY COWS
A method of enhancing milk production efficiency in dairy cattle that comprises feeding the dairy cattle with a feed ration comprising a corn silage made from a brown midrib/floury-2 corn hybrid. Upon being fed to dairy cows, a feed ration comprising brown midrib/floury-2 corn silage provides at least about 4% higher in the amount of milk produced per unit of the feed intake, compared to a feed ration comprising non-brown midrib corn silage.
1 . A method of enhancing milk production efficiency in dairy cattle, the method comprising:
preparing a feed ration comprising a corn silage made from a brown midrib/floury-2 corn hybrid; and
feeding the dairy cattle with the feed ration to provide an increased amount of milk produced per one unit of the feed ration consumed by the dairy cattle.
2 . The method of claim 1 , wherein the amount of milk produced per one unit of the feed ration consumed is at least about 4% higher for the feed ration comprising the brown midrib/floury-2 corn hybrid compared to a feed ration comprising brown midrib corn hybrid without a floury-2 genotype.
3 . The method of claim 1 , wherein the brown midrib corn hybrid is a bm3/fl2 corn hybrid.
4 . The method of claim 1 , wherein the feed ration comprises the corn silage in an amount from about 40% to about 60% on dry matter basis.
5 . The method of claim 1 , wherein the feed ration comprises from about 40% to about 60% of the corn silage, from about 5% to about 15% of alfalfa silage, and from about 5% to about 15% of ground corn gain based on dry matter basis.
6 . The method of claim 5 , wherein the feed ration further comprises at least one ingredient selected from the group consisting of soybean meal, soyhulls, dried distillers gains with solubles, animal or vegetable fat, mineral salt, sodium bicarbonate, limestone, dynamite, dicalcium phosphate, trace nutrient premix, and combinations thereof.
7 . The method of claim 1 , wherein feeding the dairy cattle with the feed ration comprising a brown midrib/floury-2 corn silage provides a higher energy amount per one unit of the feed ration consumed by the dairy cattle, compared to feeding the dairy cattle with a feed ration comparing silage prepared from a brown midrib corn without a floury-2 genotype.
8 . A feed ration comprising, on dry matter basis:
from about 40% to about 60% of bm/fl2 corn silage;
from about 5% to about 15% of alfalfa silage; and
from about 5% to about 15% of ground corn gain,
wherein upon being fed to a dairy cattle, the feed ration provides an increased amount of milk produced per one unit of the feed ration consumed by the dairy cattle.
9 . The feed ration of claim 8 , wherein the corn silage is made from a bm3/fl2 corn hybrid.
10 . The feed ration of claim 9 , wherein upon being fed to a dairy cattle provides a higher proportion of nitrogen consumed partitioned to milk than a feed ration comprising corn silage made from a brown midrib corn hybrid without a floury-2 genotype.
11 . The feed ration of claim 9 , wherein the feed ration has a high concentration of starch and lower concentration of neutral detergent fiber (NDF) than a feed ration comprising corn silage made from a brown midrib corn hybrid without a floury-2 genotype.
12 . The feed ration of claim 9 , wherein the corn silage is made from a FBDAS1 corn hybrid.
13 . The feed ration of claim 12 , wherein upon being fed to a dairy cattle provides at least about 4% higher in an amount of milk produced per one unit of the feed ration consumed by the dairy cattle, compared to a feed ration comprising corn silage made from a brown midrib corn hybrid without a floury-2 genotype.
14 . The feed ration of claim 12 , wherein upon being fed to a dairy cattle provides a higher energy per one unit of the feed ration consumed by the dairy cattle, compared to a feed ration comprising corn silage made from a brown midrib corn hybrid without a floury-2 genotype.
15 . The feed ration of claim 12 , wherein upon being fed to a dairy cattle provides a higher starch digestibility than a feed ration comprising corn silage made from non-brown midrib corn hybrid.
16 . The feed ration of claim 8 , further comprising at least one ingredient selected from the group consisting of soybean meal, soyhulls, dried distillers gains with solubles, animal or vegetable fat, mineral salt, sodium bicarbonate, limestone, dynamite, dicalcium phosphate, trace nutrient premix, and combinations thereof.
17 . The feed ration of claim 8 , comprising about 46% the corn silage, about 10% the alfalfa silage, and from about 7.5% to about 12% of the ground corn gain on dry matter basis.
18 . Corn silage produced from a brown midrib/floury-2 corn FBDAS1 hybrid.
19 . The corn silage of claim 18 , wherein upon being formulated into a feed ration and consumed by a dairy cattle provides a higher amount of milk produced per one unit of the feed ration consumed by the dairy cattle, compared to a feed ration comparing a corn silage produced from a brown midrib corn hybrid without a floury-2 genotype.
20 . The corn silage of claim 18 , wherein upon being formulated into a feed ration and consumed by a dairy cattle provides a higher energy amount per one unit of the feed ration consumed by the dairy cattle, compared to a feed ration comparing a corn silage produced from a brown midrib corn hybrid without a floury-2 genotype.
