Proteins: Dietary Sources and Requirements

2.1K
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...

Industrial insulin production uses genetically engineered E. coli expressing a proinsulin gene controlled by a tryptophan promoter and containing a methionine linker for later cleavage. The cells also carry ampicillin resistance for selective growth. Seed cultures are stored at −80 °C and production begins by thawing a small amount to inoculate starter cultures, which are progressively scaled to a 50,000-L bioreactor. In the bioreactor, E. coli grow in nutrient-rich media under...

Upstream processing represents a critical phase in biomanufacturing, wherein biological systems such as microorganisms, mammalian cells, or insect cells are cultivated to produce therapeutic proteins, vaccines, enzymes, or other biologically derived products. This phase encompasses all steps from the selection and genetic manipulation of the production organism to the cultivation of cells in bioreactors under tightly controlled environmental conditions.Host Selection and Genetic OptimizationThe...

Summary

Replacing corn with rice in broiler chicken pre-starter diets improves nutrient digestibility and growth performance. Soy protein isolate inclusion did not enhance performance, suggesting rice is a superior alternative ingredient.

Area of Science:

  • Animal Science
  • Poultry Nutrition
  • Feed Science

Background:

  • Corn and soybean meal, common pre-starter feed ingredients, exhibit suboptimal digestibility in broiler chickens.
  • Optimizing nutrient utilization during the critical pre-starter phase (1-7 days) is crucial for overall broiler performance.

Purpose of the Study:

  • To evaluate the efficacy of substituting corn with white rice (WR) or parboiled rice (PR) in broiler pre-starter diets.
  • To assess the impact of including 6% soy protein isolate (SPI) on nutrient digestibility and broiler performance.
  • To investigate the influence of feed form (pellet vs. mash) and oil content on feed intake and performance.

Main Methods:

  • Three experiments were conducted involving broiler chickens from 1 to 21 or 33 days of age.
  • Diets featured substitutions of corn with WR or PR, and included 6% SPI.
  • Evaluated parameters included coefficients of total tract apparent retention (CTTAR), ileal and jejunal starch digestibility, and overall broiler performance metrics.

Main Results:

  • Rice-based diets (WR or PR) significantly outperformed corn-based diets in CTTAR, starch digestibility, and broiler performance.
  • Inclusion of 6% SPI led to improved CTTAR (excluding Nitrogen) but reduced feed intake, negatively impacting performance.
  • SPI inclusion did not consistently improve broiler performance across all experiments.

Conclusions:

  • Replacing corn with either white or parboiled rice in pre-starter diets enhances nutrient digestibility and broiler growth performance.
  • Soy protein isolate at 6% is not recommended for pre-starter diets due to potential negative effects on feed intake and performance.
  • Rice presents a more digestible and effective alternative to corn for optimizing broiler chicken nutrition during the early developmental stages.
