1. A process for producing a feedstuff for an animal, the process comprising a step of:
(i) harvesting vegetative plant parts from a transgenic Sorghum species plant or a transgenic Zea mays plant, the vegetative plant parts being transgenic for at least (a) a first exogenous polynucleotide which encodes a plant Wrinkled 1 (WRI1) polypeptide operably linked to a heterologous promoter which is effective to direct expression of the first exogenous polynucleotide in the Sorghum species or Zea mays vegetative plant parts and increase the level of the WRI1 polypeptide relative to a corresponding wild type vegetative plant part, and (b) a second exogenous polynucleotide which encodes a plant diacylglycerol acyltransferase (DGAT) polypeptide operably linked to a heterologous promoter which is effective to direct expression of the second exogenous polynucleotide in the Sorghum species or Zea mays vegetative plant parts and increase the level of the DGAT polypeptide relative to the corresponding wild type vegetative plant part, whereby the vegetative plant parts comprise a total fatty acid (TFA) content which comprises fatty acids esterified in the form of triacylglycerols (TAG) and fatty acids in the form of lipids other than TAG, wherein the vegetative plant parts comprise a TFA content of between 6% and 20% (w/w dry weight) and a TAG/TFA Quotient (TTQ) of between 0.60 and 0.84, or between 0.84 and 0.95, and one or more of the following steps:
(ii) admixing the harvested plant parts with at least one other feed ingredient,
(iii) baling the harvested plant parts,
(iv) processing the harvested plant parts by chopping, cutting, drying, pressing or pelleting the plant parts, and
(v) storing the harvested plant parts under conditions of reduced oxygen for a period of time until at least some carbohydrates in the plant parts are fermented to organic acids.
