摘要

以黑孟加拉山羊皮为研究对象,研究其被毛颜色的物理参数和组织结构特征。随机选取500张皮肤,用科学仪器测量,采用红木精-伊红染色法进行组织学研究。黑色毛色皮肤最高(58%),黑孟加拉山羊皮肤平均重998.80 gm,长29.24 cm,宽20.91 cm,但各组间差异不显著。臀区、铃区、肩区皮肤平均厚度分别为1.97、1.43、1.96 mm,各组间差异均有统计学意义。所有被屠宰的山羊都使用“Muchki”(吊装和握拳)方法剥皮。平均剥皮长度为20.2 mm,剥皮深度为1.50 mm,机械损伤和寄生损伤分别为6.11%和1.50%。非食用肉质副产物产量差异不显著(p > 0.05),但切边副产物产量和腌制需盐量差异显著(p < 0.05)。盐渍皮平均保存3.5天。黑孟加拉山羊黑色、棕色、白色和混合被毛的毛囊、皮脂腺、竖毛肌肉、胶原纤维和纤维束在臀部区域比肩部和腹部区域更有规律。

Characterization and grading of Black Bengal goat skin based on coat color
The research was conducted to study physical parameters and histological structural patterns based on the coat color of Black Bengal goat skins. Five hundred skins were randomly selected, and measured using scientific instruments and the Haematoxylin-Eosin staining method was used for histological study. Black coat color skin was found the highest (58%), the mean weight, length, and width of Black Bengal goat skin was 998.80 gm, 29.24, and 20.91 cm, respectively but there were no significant differences among the groups. The mean thickness of the skin was 1.97, 1.43, and 1.96 mm in the butt, bell, and shoulder regions, respectively, and significantly different between the groups in all categories. All slaughtered goats were flayed using the “Muchki” (Hoisting and fisting) method. The average flay cut length, depth, and mechanical and parasitic damages were 20.2 mm, 1.50 mm, 6.11, and 1.50 %, respectively. No significant difference (p > 0.05) was found in inedible fleshing by-products, but significant differences (p < 0.05) were found in trimming by-products production and salt required for curing. Salted skins were preserved for an average of 3.5 days. Hair follicles, sebaceous glands, erector pili muscles, collagen fibers, and fiber bundles were more regular in the butt region than shoulder and belly regions in the black, brown, white, and mixed coat color of Black Bengal goat skins.
