SLAUGHTER LAMBS, YEARLINGS, AND SHEEP SOURCE: §§ 53.130 to 53.134 appear at 23 F. R. 9407, Dec. 5, 1958.

§ 53.130 Market sheep. The official standards for market sheep, developed by the United States Department of Agriculture, provide for segregation according to (a) use as slaughter animals or feeders; (b) class or sex conditions; (c) age group; and (d) grade, which is determined by the apparent relative excellence and desirability of the individual animal for a particular use.

§ 53.131 Slaughter classes and market groups. The classes of slaughter sheep are ram, ewe, and wether; the age groups are lambs, yearlings, and sheep. Definitions of the respective classes and age groups are as follows:

(a) Ram. A ram is an uncastrated male ovine.

(b) Ewe. A ewe is a female ovine.

(c) Wether. A male ovine castrated when young and prior to developing the secondary physical characteristics of a

ram.

(d) Lamb. A lamb is an immature ovine, usually under 14 months of age, that has not cut its first pair of permanent incisor teeth.

(e) Yearling. A yearling is an ovine usually between one and two years of age, that has cut its first pair of permanent incisor teeth but has not cut the second pair.

(f) Sheep. A sheep is an ovine, usually over 24 months of age, that has cut its second pair of permanent incisor teeth.

[blocks in formation]

grade of a slaughter lamb or sheep is determined by a composite evaluation of two general considerations which influence carcass excellence, conformation and fatness, maturity, and other factors responsible for differences in quality of the lean flesh.

(1) Conformation refers to the general body proportions of the animal and to the ratio of meat to bone. Although primarily determined by the inherent muscular and skeletal systems, it is also influenced by the degree of fatness. Excellent conformation in slaughter lambs and sheep is denoted by a compact, widetopped, straight-lined, thick-fleshed individual that is deep and full in the twist. Fullness and thickness should be especially evident in the portions of the body producing the more desirable cuts of meat-loin, rack, and legs.

(2) In grading slaughter lambs and sheep, quality of the lean flesh must necessarily be evaluated indirectly from consideration, primarily, of the quantity, distribution, and type of fat or finish in relation to the maturity of the animal being graded. Limited consideration is also given to such factors as character of bone and smoothness and symmetry of body. Finish is evaluated by noting variations in the fullness and apparent thickness of the fat covering over the back, loin, ribs, and legs. A high degree of desirable finish is evidenced by a thick, firm, smooth layer of fat which is uniformly distributed over the body.

(b) General principles. (1) The determination of the carcass grade that the slaughter animal will produce requires the exercising of well-regulated judgment. Each animal presents a different combination of the grade-determining factors. Animals frequently have characteristics associated with two or more grades. Therefore, a composite evaluation of all the inherent physical characteristics is essential for accuracy in determining grade.

(2) The accurate determination of the grade of a slaughter lamb or sheep requires handling in addition to visual observation. The length and density of the fleece varies greatly with individuals and the thickness and firmness of the flesh covering of wooled lambs and sheep can only be roughly estimated without handling. The technique used in handling usually varies with the degree of precision in mind as well as the experi

mum for the upper third of the Good grade and remain eligible for Choice. Also, a development of finish which is superior to that specified as minimum for the Choice grade may compensate, on an equal basis and without limit, for a development of conformation which is inferior to that specified for Choice as indicated in the following example: A lamb which has a development of finish equivalent to the mid-point of the Choice grade may have conformation equivalent to the mid-point of the Good grade and remain eligible for Choice.

(c) Good. (1) Lambs possessing the minimum requirements for Good grade are moderately rangy, upstanding, long and thin of neck, and moderately thinfleshed. They are slightly narrow over the back, loin, and rump. Hips and shoulders are moderately prominent. The twist is slightly shallow and legs slightly small and thin. Relatively young lambs, under seven months of age, have slightly more than a very thin, uneven fat covering over the back, loin, and upper ribs. In handling, the shoulders, backbone, hips, and ribs are prominent. Older, more mature lambs have slightly more than a thin fat covering over the back, ribs, and loin. In handling, the bones of the shoulders, backbone, hips, and ribs are rather prominent. Lambs of this grade may present evidences of slightly low quality. The bones and joints are usually moderately large, and the body somewhat lacking in symmetry and smoothness.

(2) A lamb which has conformation equivalent to at least the mid-point of the Good grade may have a development of finish equivalent to the minimum for the upper third of the Utility grade and remain eligible for Good. Also, a development of finish which is superior to that specified as minimum for the Good grade may compensate, without limit, for a development of conformation which is inferior to that specified for Good on the basis of a half grade of superior finish for a third of a grade of deficient conformation as indicated in the following example: A lamb which has a development of finish equivalent to the mid-point of the Good grade may have conformation equivalent to the minimum for the upper third of the Utility grade and remain eligible for Good.

(d) Utility. (1) Lambs meeting the minimum requirements for Utility grade

are very rangy, angular, and long and thin of neck. They are very thinly fleshed, narrow over the back, loin, and rump, and shallow in the twist. The hips are very prominent and the shoulders are usually open, rough, and prominent. The legs are very small, thin, and present a slightly concave appearance. Regardless of age, Utility lambs show no visible evidence of fat covering. In handling, bones of the shoulders, backbone, hips, and ribs are very prominent. Utility grade lambs are of rather low quality. The bones and joints are proportionately large and the body is very rough and unsymmetrical.

(2) A lamb which has conformation equivalent to at least the mid-point of the Utility grade may have a development of finish equivalent to the minimum for the upper third of the Cull grade and remain eligible for Utility. Also, a development of finish which is superior to that specified as minimum for the Utility grade may compensate, without limit, for a development of conformation which is inferior to that specified for Utility on the basis of a half grade of superior finish for a third of a grade of deficient conformation as indicated in the following example: A lamb which has a development of finish equivalent to the mid-point of the Utility grade may have conformation equivalent to the minimum for the upper third of the Cull grade and remain eligible for Utility.

(e) Cull. (1) Typical Cull grade lambs are extremely rangy, angular, long and thin of neck, thin-fleshed, and extremely narrow and shallow bodied. Shoulders and hips are very prominent. The legs are extremely small, thin, and present a very concave appearance.
