DS1 Langston Dry Pellet
This pellet is another one of the institute used for pregnant goats in the last month or so before gestation. The Ca level is less than for the other pellets so that does are prepared to mobilize Ca in early lactation if necessary. The CP level in the pellet is moderate, typically fed with moderate- to high-quality forage, other than alfalfa. The trace mineral and vitamin premix is that given for S1. The calculated composition of the pellet on a dry matter basis is:
CP – 15% | |
TDN – 76.2% | |
Ca – 0.47% | |
P – 0.46% | |
Cu – 14.6 ppm | |
Se – 0.33 ppm | |
Zn – 141 ppm | |
Ingredient | % (air dry basis) |
Cottonseed hulls | 14.74 |
Alfalfa meal | 20.00 |
Wheat midds | 22.90 |
Ground corn | 30.00 |
Soybean meal | 6.50 |
Pellet partner | 5.00 |
Calcium carbonate | 0.11 |
White salt | 0.50 |
Trace mineral and vitamin premix | 0.25 |
DS2 Lactation Supplement
The DS2 is a concentrate-based supplement being used in an experiment with grazing and confined dairy goats in early, mid- and late lactation. It is being fed at two different levels – 0.33 or 0.66 kilograms (0.73 or 1.46 pounds, respectively) per kilogram of milk being produced over 1.5 kilogram. This is the same as 0.33 or 0.66 pounds per pound of milk produced over 3.3 pounds. Trace mineral and vitamin premixes are those used for CD2. The calculated analysis on a dry matter basis is:
CP – 15.7% | |
TDN – 85% | |
Ca – 0.74% | |
P – 0.38% | |
Ingredient | % (dry matter basis) |
Rolled corn | 74.5 |
Whole cottonseed | 5.0 |
Soybean meal | 16.0 |
Sodium bicarbonate | 2.0 |
Dicalcium phosphate | 0.2 |
Limestone | 1.6 |
Mineral oil | 1.0 |
Vitamin premix | 0.7 |
