Abstract
ABSTRACT The objective of this study was to evaluate the effect of guava agroindustrial waste (GAW) on ruminal parameters (pH, N-NH3, and microbial protein), volatile fatty acid (VFA), and morphometry of the rumen and intestine of sheep. A total of forty Santa Ines sheep (120 days old and 21.3±2.62 kg) were used. The animals were fed diets with 0, 7.5, 15, 22.5, and 30% inclusion of GAW. The pH, ammonia nitrogen, microbial protein, and VFA were evaluated in the ruminal [...]
Highlights
The low-cost feed ingredients based on agroindustrial byproducts are potential alternatives that can reduce the cost of mixed feed, but the effects of these ingredients on animal performance and final products need to be further considered (Whitney and Smith, 2015)

The pH, ammonia nitrogen, microbial protein, and VFA were evaluated in the ruminal fluid, alongside the morphometric characteristics of the rumen and intestine
Summary
The low-cost feed ingredients based on agroindustrial byproducts are potential alternatives that can reduce the cost of mixed feed, but the effects of these ingredients on animal performance and final products need to be further considered (Whitney and Smith, 2015). Some of these discarded wastes are considered pollutants, but most can be used to feed ruminants, reducing production costs by turning low-nutrient residues into high-value products such as meat and milk (Geron et al, 2015; Hassan et al, 2016). The GAW has low degradability in the ruminal environment, which may interfere with the availability of nutrients (carbohydrates and proteins) for the production of microbial protein due to the high contents of anti-nutritional components such as tannin and lignin, thereby reducing the digestibility of the feed (Chang et al, 2014)
