SECTION 61.43. Cottonseed Screenings: Sampling, Analysis, and Labeling

(a) Notwithstanding the provisions of §61.41 of this title (relating to Sampling and Analytical Procedures), when samples of cottonseed screenings are to be obtained, for purposes of uniformity such samples shall be taken from the shipping vehicle after loadout by probing vertically into the lot. The sample shall be obtained utilizing the Missouri D tube, a double tube open-sleeve trier, or the 552 grain probe, a double tube compartment trier. Other sampling devices may be used if previously approved by the Office of the Texas State Chemist, Feed and Fertilizer Control Service. Specifications for the two triers are as follows:

(2) Available from Seedboro Equipment Co., 1022 West Jackson Boulevard, Chicago, Illinois 60607.

(b) To obtain a proper sample with the Missouri D tube, the probe is inserted into the lot in the open position, closed, then withdrawn. The 552 compartmented trier, when employed, is inserted to the desired depth in the closed position, opened, filled, closed, and withdrawn.

(c) Fifteen probes shall be acquired, following either of the random probe patterns shown in the following illustration.

(d) The probes shall be composited to form the sample. The entire sample shall be ground to pass a sieve with a 1-millimeter diameter (1/25 inch) and mixed thoroughly prior to obtaining an aliquot for analysis. The sample shall be analyzed for the following components using the indicated methods, which were adopted in the Official Methods of Analysis of the Association of Official Analytical Chemists, 14th Edition (1984), or these methods as amended in subsequent editions of this reference; that is: Crude protein-Method 7.015 (Kjeldahl); Crude fat-Method 7.061; and Crude fiber-either Method 7.066 or 7.071; and no other.

(e) Cottonseed screenings shall be sampled for analysis from time to time by the Feed and Fertilizer Control Service in such manner as to verify the compositional range of this by product. The compositional information shall be made available in the annual report on commercial feeds published by the Feed and Fertilizer Control Service.

(f) At the time of introduction into commerce and thereafter, such by product shall be labeled "Cottonseed Screenings.' The label shall affirmatively state that the product was obtained in the normal and regular course of commercial delinting and processing of cottonseed for planting purposes, and has been subsequently handled so as not to adversely affect its content. Required label guarantees relating to nutrient analysis of cottonseed screenings may conform with the compositional information generated by the Feed and Fertilizer Control Service, provided that the label shall be expressed in the format described under the Act, §141.051 (a).
