Livestock nutrition is a crucial aspect of animal agriculture. Various factors, including genetics, environment, and health, affect animal production and profitability. Proper nutrition is necessary to maintain the health and well-being of animals. This review aims to highlight the importance of livestock nutrition while discussing the various aspects involved in animal feeding [1].

In livestock production, proper nutrition is essential in achieving maximum production efficiency, optimal growth, and high-quality end products. The primary objective of livestock nutrition is to provide a balanced diet that meets the nutritional needs of specific animals at different stages of growth and production. Livestock animals have different feeding requirements and nutrient needs according to their species, age, weight, and reproductive status [2].

Feeding forages and roughages is crucial for the proper development and maintenance of the rumen and its bacterial ecosystem. Grazing practices provide animals with access to fresh forages, which are a valuable source of energy, protein, fiber, and minerals, vital in ensuring proper rumen fermentation. Forage-based diets are the cheapest and most natural feeding options; however, nutrient quality may vary depending on the forage type, soil fertility, and weather conditions [3].

In addition to forage, concentrate feeds are essential in meeting the nutritional needs of livestock animals. Concentrate feeds include grains, oilseed meals, and animal protein products. Concentrate feeds are dense with energy and protein, making them an excellent source of nutrition, particularly for animals with high nutrient requirements, such as lactating and growing animals. The right combination and proportion of concentrate feeds to forages can improve animal performance, milk production, and carcass characteristics [4].

Nutrient requirements for livestock vary, depending on the animal species, breed, age, and physiological stage. For instance, growing animals require high-quality protein, while lactating animals need more energy-dense feeds. Additionally, minerals and vitamins play a critical role in animal production, particularly when it comes to immune regulation, bone development, and metabolism. The proper balance of essential micronutrients is essential in achieving the optimal health and performance of livestock animals [5].

Water is often overlooked but is a crucial nutrient in livestock feeding. Access to clean and fresh water is essential in maintaining normal physiological functions in animals. Animals require adequate water for digestion, metabolism, and thermoregulation. Additionally, lack of water can result in dehydration, electrolyte imbalances, and health problems [6].

Feed quality and safety are critical in livestock nutrition. Contaminated feeds may lead to animal health problems and can pose potential risks to human consumers of animal products. Feeds that contain excessive levels of mycotoxins, heavy metals, or other contaminants can cause health problems in animals, reduce productive performance, and even cause death. Farmers should ensure that their feeds are of good quality, free from contaminants, and provide necessary nutritional value [7].

Genetic modification has gained much attention in animal agriculture and offers several potential benefits, including increased feed efficiency, disease resistance, and animal productivity. Genetic engineering allows for the development of novel feeds with higher nutritional values, lower anti-nutritional factors, and disease resistance. However, strict regulations are necessary to ensure the safety of genetically engineered feed and their potential impact on animal and human health [8].

Factors affecting animal production

There are numerous factors that affect animal agriculture, including

Weather and climate change: The changes in weather conditions and climate patterns have a significant impact on animal agriculture. Extreme heat or cold temperatures can affect livestock growth and productivity and affect the availability of food and water for animals. Climate change can lead to droughts, floods, and other weather events that can negatively affect animal agriculture [9].

Technology and innovation: The use of technology and innovation has transformed animal agriculture by improving the quality and quantity of meat, milk, and other animal products and making farming more efficient. Technologies such as genetic engineering, artificial insemination, and precision farming have made it possible to produce more food with fewer resources [10].

Government policy: The government plays a significant role in animal agriculture through the regulation of food safety, animal welfare, and environmental protection. Government policies, such as subsidies and tariffs, can affect the price of animal products, which can impact the profitability of farmers [1, 2].

Market demand: The market demand for animal products determines the production levels of farmers. Changes in consumer preferences, as well as economic conditions, can impact the demand for animal products, which can either help or hurt farmers [4, 5].

Animal welfare and ethics: The treatment of animals in agriculture has become a point of concern for many consumers and animal welfare organizations. The use of practices such as confinement, anabolic steroids, and growth hormones are all considered unethical by some groups, and this can lead to changes in animal agriculture practices [8].

In result, animal agriculture is impacted by several factors which contribute to the overall success and sustainability of the industry.Livestock nutrition is a critical component of animal agriculture and has significant impacts on animal productivity, health, and welfare, as well as the quality and safety of animal products [10]. A balanced diet that provides all essential nutrients is essential for optimal animal performance. The right combination of forages and concentrates, along with adequate water and micronutrients, is crucial in achieving maximum animal productivity. Good feed quality and safety are also crucial to ensure the health and well-being of livestock animals while minimizing potential health risks to consumers. Further research and innovations in feed technology will undoubtedly enhance livestock nutrition and productivity in the future.
