bcs.gain.cow: Nutrient Requirements to Increase Cow Body Condition Score

In sgadberry/beefnrc: Functions Based on Nutrient Requirements of Beef Cattle

Description

bcs.gain.cow Nutrient requirements to increase body condition score of mature cows or previously Calved first-calf heifers during the 3rd trimester following weaning

Usage

bcs.gain.cow(breed.code = 1, mbw.lbs = 1200, initial.bcs = 4,
  target.bcs = 6, first.calf = FALSE)

Arguments

breed.code	Default is 1 = Angus. Breed code must match a code listed in the table 19_1 data file.
mbw.lbs	Default is 1200. This value represents the mature, unshrunk bw (lbs) for cows > 3 yrs old. For first calf heifers, calving at 2 yr is assumed. mbw.lbs is the estimated mature weight for first calf heifers, and equations are based on a shrunk bw of 0.85(mbw) at first calving and 0.9(mbw) at second calving.
initial.bcs	Default is 4. This value represents the body condition score at the end of the 2nd trimester or at calf weaning.
target.bcs	Default is 6. This value represents the target body condition score at calving.
first.calf	Default is FALSE. Change to TRUE to adjust requirements for first calf heifers.

Value

Three tables are printed including nutrient requirement totals, nutrient requirement as a proportion of dry matter intake, and a third table whereby crude protein is adjusted to a ratio of 6:1 for tdn:cp.

Examples

bcs.gain.cow()
bcs.gain.cow(target.bcs=5)
bcs.gain.cow(first.calf=TRUE)
