Abstract The objective of this study was to establish mathematical models to predict the chemical constituents of the empty body and carcass from the rib section. The database was composed of five independent experiments, comprising a total of 171 experimental units consisting of 133 noncastrated males, 26 castrated males, and 12 females. The most representative breeds in the database were Santa Ines (n = 58), Morada Nova (n = 74), and Brazilian Somali (n = 39). In the current study, the following independent variables were included using the rib section: water (Waterrib, %), crude protein (CPrib, %), ether extract (EErib, %) energy (Energyrib, Mcal/kg), visceral fat (VF, % EBW), organs plus viscera (OV, % EBW), carcass dressing (CD, % EBW), hot carcass weight (HCW, kg) and empty body weight (EBW, kg). The EErib was the most significant variable (P

使用肋骨部分的成分预测毛羔羊的化学身体成分

摘要 本研究的目的是建立数学模型，从肋骨部分预测空身和胴体的化学成分。该数据库由五个独立的实验组成，共包括 171 个实验单位，其中包括 133 名未阉割的男性、26 名阉割的男性和 12 名女性。数据库中最具代表性的品种是 Santa Ines (n = 58)、Morada Nova (n = 74) 和巴西索马里 (n = 39)。在目前的研究中，使用肋骨部分包括以下自变量：水（Waterrib，%），粗蛋白（CPrib，%），醚提取物（EErib，%），能量（Energyrib，Mcal/kg），内脏脂肪（ VF, % EBW)、器官加内脏 (OV, % EBW)、屠体敷料 (CD, % EBW)、热屠体重量 (HCW, kg) 和空体重 (EBW, kg)。EErib 是最显着的变量（P
