"氢氰酸 (mg/kg)": "木薯、苦杏仁等原料中潜在剧毒物质，阻断细胞呼吸，极微量即可引起猪中毒死亡。构树原料标0为已脱毒处理，使用前必须确认氢氰酸含量合格。",
"总黄酮 (mg/kg)": "构树等植物次生代谢物，具有抗氧化、抗菌、改善血管功能的作用，对母猪繁殖性能和仔猪抗应激有一定正面作用，但过量也可能影响适口性。",
"生物碱 (mg/kg)": "构树等原料中潜在有害物质，高量会引起猪神经症状、食欲下降甚至中毒，使用时需严格控制比例。",

"杜长大 (DLY)": {
"description": "杜长大是中国市场占有率最高的商品肉猪。通过利用杜洛克、长白、大约克三品种的杂种优势，实现高效生长和高瘦肉率。",
"parent_info": "终端父本：杜洛克 (D)；二元母本：长白 (L) × 大约克 (Y)。",
"appearance_features": "全身白色，体型健壮、体躯较长，肌肉发达，背腰平直。",
"breed_advantages": "生长速度快、日增重极高、饲料转化率最优、瘦肉率稳定在60%以上、适应性良好、出栏时间最短。",
"breed_disadvantages": "抗应激能力中等，对疫病和环境变化相对敏感；无法作为种猪进行自繁。"
},
"杜大长 (DY L)": {
"description": "杜大长是另一种重要的外三元猪，与杜长大体系相似，但在母本的搭配上有所区别，同样追求高生长速度和高瘦肉率。",
"parent_info": "终端父本：杜洛克 (D)；二元母本：大约克 (Y) × 长白 (L)。",
"appearance_features": "全身白色，体型比杜长大略微魁梧，肌肉丰满度高。",
"breed_advantages": "生长性能和瘦肉率与杜长大相当，同时遗传了大约克母本的良好体型和生长潜力，综合性能优秀。",
"breed_disadvantages": "与杜长大相似，无法留作种用，需要依赖稳定的种源体系；对饲养管理要求高。"
},
"皮长大 (PL Y)": {
"description": "皮长大是以皮特兰作为终端父本的杂交体系，专注于生产超高瘦肉率的商品肉猪。",
"parent_info": "终端父本：皮特兰 (P)；二元母本：长白 (L) × 大约克 (Y)。",
"appearance_features": "多数为白色或带有黑色斑点，肌肉极其发达，后臀饱满，体型呈方形。",
"breed_advantages": "瘦肉率极高（能达到65%以上），胴体丰满，背膘薄。",
"breed_disadvantages": "生长速度和日增重逊于杜长大；应激敏感性极高（易发生P.S.S.），管理难度大，肉质易出现PSE（苍白、软、渗水）现象，影响口感和加工性能。"

},
"pig_age_stages": {
"保育期": "从断奶到转入生长舍。主要目标是适应固体饲料，建立肠道菌群，确保健康稳定过渡，体重约5kg~30kg。",
"育肥前期": "小猪转入育肥舍后到体重达到约60kg的阶段。以骨骼和肌肉生长为主，是高效增重期。",
"育肥后期": "体重从约60kg到达到出栏体重（约110-120kg）的阶段。脂肪沉积速度开始加快，是出栏前的冲刺期。",
"二次育肥期": "指收购达到常规出栏体重（约100-120kg）的商品猪，继续饲养至更大体重（140-180kg+）的阶段。其存在主要受市场价格波动驱动，目的是提高单体出肉量。"
