概括

在 brojiler料中减少原蛋白 (CP) 或大豆粉 (SBM) 可以降低环境影响,而不会损害鸟类的表现. 低CP和有限SBM饮食都显著减少了料料的数量.

科学领域:

动物科学动物科学
环境科学环境科学
农业科学农业科学

背景情况:

欧洲家禽产业面临着环境挑战,包括大量进口大豆粉 (SBM).
减少家禽饮食中的原蛋白 (CP) 和SBM含量是一种减轻环境影响的策略.

研究的目的:

评估低原蛋白 (CP) 和减少大豆粉 (SBM) 饮食对肉的表现,尸体参数和料的全球变暖潜力 (GWP) 的影响.
确定这些饮食修改是否可以在不损害鸟类生产力或环境可持续性的情况下实施.

主要方法:

一项涉及1350只雄性Ross 308鸟类在六种饮食治疗中进行的研究.
饮食包括在开始,种植和完成阶段不同程度的CP降低,SBM含量减少到15% (低) 或0% (零).
用OpteinicsTM计算了料的GWP,并使用线性回归模型分析了性能数据.

主要成果:

与阳性对照组相比,低CP饮食没有对表现,尸体重量或乳房肉重量产生负面影响.
在35天内,养低或零SBM饮食的肉体重,体重增加和料转换比率 (FCR) 均高于其他肉.
与对照组相比,低CP和减少SBM策略都显著改善了料GWP.

结论:

低CP饮食在35天的时间内对肉生产是可行的,对性能没有不利影响.
与传统的基于SBM的饮食相比,低SBM和零SBM饮食可以提高 brojler的性能和尸体产量.
实施低CP或减少SBM饮食提供了改善 brojler生产和减少料GWP的双重好处.

Production Efficiency

Production Efficiency

Net production efficiency (NPE) is the efficiency at which organisms assimilate energy into biomass for the next trophic level. Due to low metabolic rates and less energy spent on thermoregulatory processes, the NPE of ectotherms (cold-blooded animals) is 10 times higher than endotherms (warm-blooded animals).

Proteins: Dietary Sources and Requirements

Proteins: Dietary Sources and Requirements

Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...

Energy Budgets

Energy Budgets

Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...
