“…In this sense, vegetal protein sources SBM and CM and animal protein sources SM and KM presented high TAAR values with stomach extract hydrolysis in both SRS stages. Soybean and canola exhibit a high content of antinutrient factors that affect the nutritional quality of plant proteins by the action of proteinase inhibitors (Ebrahimi‐Mahmoudabad & Taghinejad‐Roudbaneh, ; Moyano‐López, Martínez‐Díaz, Díaz‐López, & Alarcón‐López, ).

The aim of this study was to compare in vitro protein digestibility between two groups of fish, at early (21 g) and late stages (400 g) of spotted rose snapper Lutjanus guttatus, to evaluate the degree of hydrolysis (DH) and total amino acid release (TAAR) using crude extracts from stomach, pyloric caeca and intestine of 13 protein ingredients including marine, animal and plant meals. Degree of hydrolysis and TAAR were measured by a pH-Stat method, and the PAGE-Zymogram was also used as complementary technique. Differences in DH were found between both grow-out stages mainly in the alkaline hydrolysis phase. Fish and squid meals (marine sources) had the highest DH and TAAR, followed by porcine meat and poultry meal byproducts from recycling sources, and soybean and canola meals (plant sources), which represent better protein sources for use in practical diets. Stomach zymograms showed two pepsin isoforms in both grow-out stages. Pyloric caeca and intestine zymograms showed five bands with proteolytic activity in the early grow-out stage, whereas four additional bands were found in late grow-out stage. Alkaline proteases were identified as serine and metalloproteases. Thus, L. guttatus presents an ontogenetically differentiated digestive enzyme pattern that modifies the DH and TAAR of different protein sources.

A 5‐week feeding trial was conducted to assess the effect of gamma ray irradiation treatment on soybean meal as a fish meal substitute in diets for golden pompano (Trachinotus ovatus). A diet containing 32% fish meal served as a reference (C), and 75% of the fish meal was replaced by soybean meal that either received no gamma ray irradiation (R0) or was irradiated with gamma ray at a dose of 5 (R5), 10 (R10), 15 (R15), 30 (R30) or 60 (R60) kGy respectively. All the diets were formulated to contain 46% crude protein and 6.5% crude lipid. The weight gain was higher in fish fed diets R5, R10, R15 and R30 than in fish fed diet R0. The feed intake was higher in fish fed diets R15, R30 and R60 than in fish fed diets R0, R5 and R10. No significant differences were found in feed conversion ratio, nitrogen retention efficiency, condition factor, hepatosomatic index, body composition, waste outputs of nitrogen and phosphorus between fish fed the diets with non‐irradiated soybean meal or irradiated soybean meal as the fish meal substitute. Proteins with heavy molecular weight in soybean meal were degraded, whereas the contents of proteins with light molecular weight or peptides increased with the increase in the irradiation dose. This study reveals that gamma ray irradiation at a dose of 5 to 15 kGy can significantly improve the level of soybean meal inclusion as a fish meal substitute in diets for golden pompano.

Gossypol is a phenolic compound produced by pigment glands in cotton stems, leaves, seeds, and flower buds (Gossypium spp.). Cottonseed meal is a by-product of cotton that is used for animal feeding because it is rich in oil and proteins. However, gossypol toxicity limits cottonseed use in animal feed. High concentrations of free gossypol may be responsible for acute clinical signs of gossypol poisoning which include respiratory distress, impaired body weight gain, anorexia, weakness, apathy, and death after several days. However, the most common toxic effects is the impairment of male and female reproduction. Another important toxic effect of gossypol is its interference with immune function, reducing an animal's resistance to infections and impairing the efficiency of vaccines. Preventive procedures to limit gossypol toxicity involve treatment of the cottonseed product to reduce the concentration of free gossypol with the most common treatment being exposure to heat. However, free gossypol can be released from the bound form during digestion. Agronomic selection has produced cotton varieties devoid of glands producing gossypol, but these varieties are not normally grown because they are less productive and are more vulnerable to attacks by insects.
