growing.cattle: Nutrient Requirements for All Growing Cattle.

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

Description

growing.cattle Nutrient requirements for growing cattle.

Usage

growing.cattle(breed.code = 1, Bull = FALSE, mbw.lbs = 1200,
  yearling = FALSE, target.adg = 2, from.bw.lbs = 400, to.bw.lbs = 800,
  increment.bw.lbs = 100, implant = TRUE, ionophore = TRUE,
  monensin = TRUE)

Arguments

breed.code	Default is 1 = Angus. Breed code must match a code listed in the table 19_1 data file.
Bull	Default is false. Adjustment for NEm applied when TRUE.
mbw.lbs	Default is 1200. This value represents the mature, unshrunk bw (lbs) for growing cattle at finishing or at maturity.
yearling	Default is FALSE. This value adjusts DMI for growing cattle > 11 months of age.
target.adg	Default is 2. This value should represent realistic rates of gain such as 0.5 as a low and 3.2 as a high.
from.bw.lbs	Avoid using values < 400. This sets the minimum of the range for prediction.
to.bw.lbs	This value sets the maximum of the range for prediction. Maximum should be realistic for age (calf vs yearling).
increment.bw.lbs	This value sets the incremental change between from.bw.lbs to to.bw.lbs.
implant	Default is TRUE. When Bull is TRUE, implant is overridden to non-implant factor of 0.94.
ionophore	Default is TRUE. When Bull is TRUE, ionophore is overridden to no ionophore.
monensin	Default is TRUE. When ionophore is FALSE, monensin is overridden.

Value

Two tables are printed including nutrient requirement totals and nutrient requirement as a proportion of dry matter intake.

Examples

growing.cattle()
growing.cattle(implant=FALSE,ionophore=FALSE)
