Goat Nutrition DS1 & DS2 Lactation Supplement


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
