What Ration? LEAST COST Chick Start How To Maximise Feed Intake A育种趋势 未来可以期待什么？ B衡量的标准（量化标准是什么）？ 最低成本 C育雏 如何摄入最多的饲料,GENETIC TRENDS 育种趋势,Annual Improvement Rates Cobb 500 科宝500每年的遗传进展率,Selection Pressure on Body Wt. 体重方面的选种压力,,,,Cobb Male Performance 科宝公鸡性能,Avian 48 / Cobb 500 AVIAN 48/科宝500,Grand Parent祖代,Male line 公系,Female line 母系,Line 35 x Line 35,Line 58 x,Line 12,Line 44 Line 12,Parent Stock父母代,Male Parent父母代公鸡,Female Parent父母代母鸡,Broiler 肉鸡,,,,,Hybrid Vigor – Improved Livability and FCR. Little difference in BW & FCR compared to Cobb 500 Cobb 500 - Breast muscle is wider. Avian 48 - Breast muscle longer & narrow Reduced Breast Yield BUT increased Drum Stick ≈ Similar WOG yield. 高效性能-成活率和肉料比更好 与科宝500相比，体重和肉料笔差异很小 科宝500-胸肉更宽 AVIAN 48-胸肉更长更窄 胸肉率减少，但腿肉更多 ≈ 出肉率相似,Characteristics of the Avian 48 VS Cobb 500 AVIAN 48与科宝500特点对照,B. THE LEAST COST WAY OR THE COBB WAY 最低成本的方式 或 科宝的方式,,Low Density Nutrition 低营养饲料 The Economics 经济性,,,The obvious way to increase profitability is by reducing the cost per kg of live weight produced. 提高经济效益的最好方法是降低活鸡的每公斤生产成本,Many companies, however, measure production efficiency with indicators like EPEF (Feed Conversion, Mortality and Average Daily Gain ) 然而，许多公司喜欢使用如EPEF的指标去衡量生产效率（饲料转化率，死亡率和每天增重）,A drive to maximise Broiler physical performance is not always the most cost effective business strategy最求肉鸡的最高生长表现不一定是最有效的经济策略,,Managing Broilers for Profit 为盈利为目的去管理肉鸡 Adjusting Nutrient Density to the bird’s requirement 根据肉鸡的要求调整营养标准,,,% reduction in feed cost – Lysine - does not always result in the same % increase in FCR!!! 饲料成本下降的幅度 %-赖氨酸-不一定导致肉料比数值提高相同的幅度%,Depending on initial levels - a reduction in nutrient density (essential Amino Acids) MAY not cause performance loss. 与最初的营养水平相关 – 营养水平的下降（必须的氨基酸）不一定导致性能的下降,Lysine – Indicator of the cost of a ration 赖氨酸-成本的合理指标,Effects of Lysine on BW, FCR & WM yield 赖氨酸对体重、肉料比和WM的影响,,,LEAST COST WAY 最低的成本方式,,Optimum Lysine Level 最佳的赖氨酸水平,,Local Change FCR vs. Feed Cost /kg 肉料比（FCR）VS. 每公斤饲料成本,,Customers need to be convinced that nutrition requirements are different. Cobb birds are fed “cheaper” rations than the OTHER BREEDS. 我们要说服肉鸡饲养户，科宝肉鸡的营养要求是不同的。

科宝肉鸡需要比其它品种更加“低廉”的饲料,FCR is no longer a valid comparative index… Feed Cost/ kg is the index (FCR x Diet Cost) 肉料比（FCR）不再是有效的比较指标 每公斤的饲料成本才是有效的指标（FCR x 配方成本）,,Essential Nutrients基本营养要求 Areas NOT to compromise on 不能降低的方面,,Mineral and Vitamin Nutrition 微量元素和矿物营养,Rapid Growth usually = high feed consumption = more rapid passage of digesta through the gut = shorter period for absorption of some key nutrients. 通常， 生长速度快 = 饲料消耗量高 = 内脏消化液的分泌更快 = 营养成分的吸收时间更短,Ca absorption is about 50%, however, this declines with increasing feed intake.钙的吸收大概是50%，然而，却随着饲料摄入的增加而下降,High early growth potential – VERY IMPORTANT that levels of several key micronutrients are not compromised. 早期生长速度潜力高– 几种微量元素的水平不能降低，很重要,,Response to Energy对能量的反应 Effects on FCR 对FCR的影响,,Like all birds, the Cobb bird responds to lower energy by EATING MORE!!. Cobb Energy Specifications are LOWER than the OTHER BREEDS.,Reducing consumption by increasing energy to high levels is – VERY DANGEROUS - the bird’s appetite is enormous!,Use Cobb diets for the intended periods. Example: Grower Ration - is NOT intended to go over 22 days. Energy is too low and FCR is lost quickly,AVIAN 48 Feed Formulation AVIAN 48 饲料配方,Cobb 500 Feed Formulation 科宝 500 饲料配方,,Mineral and Vitamin Requirements 矿物质和维生素的需求 Leg Disorders associated with deficiency or imbalance 与矿物质和维生素缺乏或失蘅相关的腿病,Rotated tibias - Perosis,Perosis = Manganese deficiency commonly. Tendon slips. In rotated tibias tendon remains in place,Infectious leg disorders or long bone deformities can develop after a nutritional disorder as they weakens the chicken’s legs,TD, Rickets,,Rickets- growth plate lesions Normal Ca/D deficiency P deficiency,Often between 2 and 4 weeks of age 通常在2-4周期间发生,Mineral and Vitamin Requirements 矿物质和维生素的需求 Leg Disorders associated with deficiency or imbalance 与矿物质和维生素缺乏或失蘅相关的腿病,,Tibial Dyschondroplasia (TD),Ca/P imbalances (Normal ratio = 2.1) Normally post 4 weeks of age 钙/P 失蘅（正常比例 = 2.1） 通常在4周龄以后发生,Mineral and Vitamin Requirements 矿物质和维生素的需求 Leg Disorders associated with deficiency or imbalance 与矿物质和维生素缺乏或失蘅相关的腿病,Low Density Nutrition低营养饲料 Why consider it? 为什么要考虑？,,,,CONTROL GROWTH 0 – 21d = GOOD SKELETAL HEALTH Low density = Low Cost nutrition THE KEY to growth control 0-21日龄控制体重增长 = 良好的骨骼健康 低营养 = 低成本 体重增长控制的关键,COBB 21 DAYS COMPENSATORY GROWTH 科宝在超过21日龄后出现补偿性生长,Least Cost 最低的成本,Reduced Energy and Amino Acids BUT WELL BALANCED. Lowered Live Weight Gain (ADG) & Increased FCR OPTIMAL Cost Per Kilogram of BW 降低能量和氨基酸，但仍然达到良好的均衡 体重增长率下降，同时， 肉料比（FCR）值升高 最好的 每公斤活鸡成本,Least Cost 最低的成本,Define Your Business Nutrition Requirements 根据自己的公司策略制定肉鸡的营养标准,US DATA : Least Cost VS EEI 美国数据 ： 最低。
