Zootechnie Generale Online
To evaluate a farm’s efficiency, zootechnicians use composite indices:
| Species | Key Performance Indicator (KPI) | Formula | | :--- | :--- | :--- | | Dairy cattle | Milk yield/cow/year & Lactation No. | 9,000 kg @ 3.5% fat & 3.2% protein | | Beef cattle | Average Daily Gain (ADG) | 1.2-1.5 kg/day in feedlot | | Swine | Number of piglets weaned/sow/year | > 28 piglets/year (high-performance) | | Poultry | Feed Conversion Ratio (FCR) | kg feed / kg gain = 1.5-1.7 (broiler) | | Sheep | Lambing rate & Mortality rate | > 150% lambs/ewe/year; < 10% mortality | zootechnie generale
Zootechnie Générale (General Zootechnics) refers to the art and science of raising domestic animals. Unlike specialized zootechnics (e.g., bovine, ovine, porcine), the general branch focuses on the universal biological laws and technical rules applicable to all species (monogastrics and ruminants, birds, rabbits, etc.). This paper is organized into five key sections
The evolution of zootechnics has shifted from traditional empirical methods to a rigorous scientific approach based on: interactions entre génétique
This paper is organized into five key sections corresponding to the fundamental functions of the domestic animal: being (genetics), eating (nutrition), reproducing (reproduction), behaving (ethology), and living (environment).
La zootechnie générale étudie l’élevage des animaux domestiques : objectifs (production, reproduction, bien-être), interactions entre génétique, alimentation, santé et environnement, et principes d’organisation des systèmes d’élevage.
