Defendant James E. Peterson purchased from plaintiff feeder heifers that developed infectious bovine rhinotracheitis (“IBR” or red nose) at some time. Peterson counterclaimed for breach of implied warranties of merchantability and fitness. Plaintiff contended that Peterson, having accepted the heifers after inspection, had excluded the warranties under a usage of the trade.
On the counterclaim a jury allowed only $526.40, the value of four head that Petеrson had refused to accept. Peterson appeals. He attacks chiefly jury instructiоns and evidentiary rulings concerning trade usage on the ground it violated public health regulations.
Pеterson, a North Platte pharmacist, owned and operated a commercial feеdlot at Big Springs. He authorized William Shannon, head cattle buyer for John Morrell and Company at Ottumwa, Iowa, to purchase for Peterson cattle suitable for the feedlot. Shannon placed the order orally with Robert D. Lowrance, president of plaintiff. Lowrance filled the ordеr by purchasing yearling heifers at sale bams in Maryville, Missouri. The health of each head at the sale was certified by Dr. Edward Powell, deputy state veterinarian of Missouri.
Lowrance hired a trucking company to transport the heifers without rest to Big Springs, 440 miles away. He *681 watched the loading of thе trailers, timely notifying Peterson’s agent of each departure. Lowrance’s commission chаrge was $0.25 cwt. Pertinent data are as follows:

17,650.03 202.88 14 140 81,150

The controversy concerns the heifers delivеred in two truck-trailers on January 14. At Big Springs neither trucker noticed a diseased animal. After inspection Joseph Ringleman, manager of the feedlot and accepter of the January 7th dеlivery, rejected four head. One had lumpy jaw. Three were depressed and feverish. Ringleman within his authority accepted the remainder with the notation “in good order.”
On January 15 three head died. Many were sick. Ringleman observed stringing mucus and drooping heads and ears. He administered mostly antibiotics to 60 head. The next day three more head were dead. On January 18 Dr. Darían Rezac first examined the animals. He approved Ringleman’s treatment. His diagnosis of IBR is undisputed. In August the death toll ended with 81 head. IBR ordinarily is not a killer in that proper treatment limits loss to 2 percent.
Clinical signs of IBR arе gauntness, fever, cough, polypnea, and mucus stringing from nostrils. Necropses by Dr. Rezac revealed typical lesions of red noses, ex-udates in tracheae, and lesions in upper respiratory tracts.
In Dr. Powell’s opinion the incidence of IBR was high in the Middle West and higher in Maryville than in localities farther north. No clinical signs of IBR appeared during his inspections at Maryville. One day to several months after exposure may elapse before clinical signs develop. Dr. Rеzac, on the other hand, estimated the period to be within a few days or a week, depending *682 on stress. In normal practice the cattle are vaccinated at the feedlot аt once, according to Dr. Powell, or after a rest, according to Dr. Rezac.
There is sufficient evidence of this usage in the trade: The buyer after inspection cuts out cattle that do not suit him, and his acceptance of cattle is irrevocable and without recourse.
Hеalth regulations promulgated by the Nebraska Department of Agriculture provide: “No animal . . . thаt is affected with or exposed to any infectious . . . disease . . . shall be . . . transported into . . . Nebraska.” Statutes provide: “It shall be unlawful for any person to knowingly . . . sell . . . any domestic animal . . . affeсted with an infectious . . . disease, except as provided by sections 54-701 to 54-753, and the . . . regulations рrescribed by the Department of Agriculture. . . . Any person so offending shall be deemed guilty of a misdemеanor ....”§ 54-750, R. R. S. 1943. “It shall be unlawful for any person to violate any . . . regulation . . . promulgated by the Department . . . pursuant to authority granted by sections 54-701 to 54-753, and any person so offending shall be deemed guilty оf a misdemeanor . . . .” § 54-751, R. R. S. 1943. The statute in our opinion requires interpolation of the word “knowingly” into the administrative regulation.
The meaning of the word “knowingly” in a criminal statute varies in the context. It commоnly imports a perception of facts requisite to make up crime. See Johnson v. Chilson,
Peterson сontends that the usage violated the Uniform Commercial Code without reference to section 2-302, U. C. C., on unconseionability. The contention is without *683 merit. . . an implied warranty can ... be excluded or modified by . . . usage of trade.” § 2-316 (3) (c), U. C. C.
The judgment is affirmed.
Affirmed.
