Summary
Nutritional supplementation is crucial for pregnant mares, especially when forage is insufficient or during out-of-season breeding. Maternal diet quality significantly impacts long-term foal health beyond basic nutritional needs.
Area of Science:
- Equine nutrition
- Reproductive physiology
- Developmental origins of health and disease
Background:
- Forage availability often meets spring/summer breeding mare needs.
- Nutritional supplementation is required for out-of-season breeding, pasture limitations, or poor forage quality.
- Current broodmare evaluations focus on fetoplacental needs, neglecting endocrine changes and long-term foal health impacts.
Purpose of the Study:
- Review current nutritional recommendations for pregnant mares.
- Outline equine fetoplacental development stages and critical gestation periods.
- Present examples of maternal nutrition's effect on long-term foal health.
Main Methods:
- Literature review of current equine nutritional guidelines.
- Examination of equine gestation physiology and developmental biology.
- Synthesis of research on maternal diet and foal health outcomes.
Main Results:
- Standard recommendations may not fully address all mare and foal needs.
- Gestation involves critical developmental periods influenced by maternal nutrition.
- Maternal diet quality has demonstrable long-term effects on foal health.
Conclusions:
- Updated nutritional strategies are needed for pregnant mares, considering endocrine factors and foal development.
- Understanding critical gestation periods is vital for optimizing foal health through maternal nutrition.
- Maternal nutrition is a key determinant of lifelong foal health, extending beyond immediate reproductive success.

01:29Oxygen Requirements and Growth Patterns
835
Microorganisms exhibit diverse oxygen requirements and growth patterns driven by their metabolic strategies and environmental adaptations. Oxygen, while essential for many organisms, can also be toxic under certain conditions, shaping how microorganisms grow and survive.Oxygen Requirements of MicroorganismsMicroorganisms are classified based on their ability to use or tolerate oxygen:● Obligate aerobes like Mycobacterium tuberculosis need oxygen for energy production, as it serves as the...

00:55Parental Care
12.1K
Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.

00:51Energy Budgets
10.1K
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...

01:28Proteins: Dietary Sources and Requirements
1.0K
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...

02:35Key Elements for Plant Nutrition
23.2K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

01:27Parentral Nutrition: Centeral and Peripheral Parental Nutrition
428
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...
