The Use of an Automated System (GreenFeed) to Monitor Enteric Methane and Carbon Dioxide Emissions from Ruminant Animals
Published on: September 7, 2015
Summary
Cattle ingest food differently due to unique digestive processes like rumination and high saliva production. Their behavior, including salt-seeking and learning, is crucial for finding nutrients like sodium.
Area of Science:
- Animal Science
- Physiology
- Behavioral Science
Background:
- Ingestive behavior in cattle is uniquely adapted for fermentative digestion.
- Rumination facilitates remastication and reinsalivation of ingested plant matter.
- High alkaline saliva secretion is necessary to buffer acidic byproducts of cellulose digestion.
Purpose of the Study:
- To explore the physiological and behavioral adaptations in cattle's ingestive behavior.
- To understand the role of taste, smell, and learning in nutrient acquisition.
Main Methods:
- Observational analysis of physiological mechanisms in cattle.
- Behavioral studies focusing on taste and smell-guided food seeking.
- Assessment of learning and memory during sodium deficiency.
Main Results:
- Cattle possess physiological mechanisms for handling large food volumes and buffering digestive acids.
- Low taste receptor thresholds and a specific drive for salt-seeking behavior were observed.
- Cattle demonstrate significant learning and memory capabilities, especially when facing sodium deficiency.
Conclusions:
- Cattle's ingestive behavior is a complex interplay of specialized digestion, sensory perception, and cognitive abilities.
- Behavioral adaptations, including salt-seeking and learning, are vital for survival and nutrient balance in cattle.
- Understanding these behaviors is key to managing cattle nutrition and health.

01:50What is Monogastric Digestion?
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.
01:02Protein Digestion
Protein digestion begins in the stomach, where the highly acidic environment can easily disrupt protein structure by exposing the peptide bonds of polypeptide chains. After polypeptide chains are broken into individual amino acids by a series of digestive enzymes, the amino acids are transported to the liver via the bloodstream to produce energy.
00:54What is Behavior?
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.
00:48Optimal Foraging
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.
01:30Regulation of Food Intake
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...
01:05Instinctive Drift
Instinctive drift refers to the tendency of animals to revert to their innate behaviors despite repeated reinforcement. Breland and Breland demonstrated this concept in an experiment with a raccoon. The raccoon was trained to pick up two coins and place them in a container in exchange for food. Initially, the raccoon learned to associate the coins with food, making them a conditioned stimulus or a substitute for food. However, over time, the raccoon became less willing to put the coins into the...
