| dc.description | Twenty-four female lambs of the Pantaneiro genetic group, with approximately 100 days of age, average body of 16.24 ± 1.78 kg, were slaughtered with 2.0, 3.0 and 4.0 mm of subcutaneous fat thickness, measured by ultrasound in the Longissimus , to evaluate the allometric growth. Lambs fed a complete pelleted diet calculated to ensure a daily weight gain of 0.30 kg. Slaughtering was performed as the female lambs re ached the pre-established fat thickness. After 24 hours in a cold chamber at 4ºC, chilled carcasses were cut in half and weighed. The right side was separated into five sections to determine the allo metry of carcasses and cuts. Neck and rib showed isogonic growth in all treatments. Loin has remained late growth to 2.0 and 3.0 mm. Shoulder and leg were isogonic growth in the treatments 3.0 and 4.0 mm. The leg in relation to half carcass showed the greatest correlation. The cuts exhibited differentiated development in the growth rates of tissues. It is recommended to slaughter female lambs when they reach 3.0 mm of subcutaneous fat thickness, since the carcass has already reached physiological ma turity. Shoulder and leg cuts are best suited for dissection for presenting the highes t correlation with the carcass in females of the Pantaneiro group. | |
