is a plant that grows naturally in northwestern Morocco and could become a promising alternative. The study was carried out to investigate the effects of hay on growth performance, carcass characteristics, and meat quality of goat kids in northern Morocco compared to .
Eighteen 3-month-old male "Beni Arouss" goat kids have been divided similarly into two groups. The control group (Luc) received lucerne hay, and the test group (YSClov) received yellow sweetclover hay, both supplemented with concentrate. Average daily gain and dry matter intake were determined during the experiment. After 99 days, goat kids were weighed, and carcass characteristics were determined. Meat quality was evaluated using samples from the semimembranosus (SM) and longissimus thoracis muscles.
The addition of YSClov significantly increased ash content ( < 0.001) and fat content ( < 0.01), reduced water holding capacity ( < 0.01), and SM pH 24 ( < 0.05). The YSClov meat was significantly more tender than the Luc meat, with corresponding values of 8.20 and 11.80 kg/cm ( < 0.05), while the Luc meat was more tender when cooked. No significant effect was found for the other parameters. The YSClov meat is richer in desirable fatty acids (DFA), while the Luc meat appears to be richer in omega-3 DFA( < 0.01).
hay showed promising results in intramuscular fat, protein content, tenderness, DFA content, and similar growth performance compared to conventional feeds.
[植物名称]是一种自然生长在摩洛哥西北部的植物,可能成为一种有前景的替代品。本研究旨在调查与[对照物]相比,[植物名称]干草对摩洛哥北部山羊羔生长性能、胴体特性和肉质的影响。
18只3月龄雄性“贝尼·阿鲁什”山羊羔被相似地分为两组。对照组(Luc)饲喂苜蓿干草,试验组(YSClov)饲喂黄花草木樨干草,两组均补充精饲料。在实验期间测定平均日增重和干物质摄入量。99天后,对山羊羔进行称重,并测定胴体特性。使用半膜肌(SM)和胸最长肌的样本评估肉质。
添加YSClov显著增加了灰分含量(P<0.001)和脂肪含量(P<0.01),降低了持水力(P<0.01)和SM的pH值24小时(P<0.05)。YSClov组的肉比Luc组的肉显著更嫩,剪切力值分别为8.20和11.80kg/cm(P<0.05),而Luc组的肉煮熟后更嫩。其他参数未发现显著影响。YSClov组的肉富含理想脂肪酸(DFA),而Luc组的肉似乎富含ω-3 DFA(P<0.01)。
与传统饲料相比,[植物名称]干草在肌内脂肪、蛋白质含量、嫩度、DFA含量和相似的生长性能方面显示出有前景的结果。
