Sut-go‘sht tipiga ega sigirlardan olingan avlodlari tajribadagi sut-go‘sht tipiga mansub sigirlarning I laktatsiyasi davrida 6,67 %-dan o‘rtacha 3280 kg onalariga nisbatan 2,67 %-ga ortiqcha yoki 9,69 %-ga sut miqdori bo‘yicha 352 kg kam bo‘ldi, 20 %-dan 3985 kg yoki onalariga nisbatan 9 % ortiqcha bo‘lib, 275 kg sut, 46,67 % sigirlar o‘rtacha 4480 kg onalariga nisbatan 65 kg, 26,67 % sigirlardan o‘rtacha 4855 kg sut sog‘ib olinib, onalariga nisbatan 45 kg sut kam bo‘lgan 73,34 %-da onalariga nisbatan ijobiy o‘zaro bog‘lanish aniqlandi. Ijobiy o‘zaro bog‘lanishga ega bu I laktatsiyadagi sut-go‘sht tipiga mansub sigirlarning sut miqdori onalari ko‘rsatkichidan o‘rtacha 55 kg yoki 1,16 %-ga kam bo‘ldi.
