“…The inclusion of soybean oil (0.36%) in the soybean diet may have contributed to the observed increase in crude protein and EE, providing the selection of certain microorganisms in the rumen environment, thereby inhibiting gram–positive bacteria and favoring a greater deposition of muscle tissue. Soybean degrades very quickly, which increases its availability to digestive enzymes and ruminal bacteria and leads to a higher amino acid concentration ( 37 ).…”

The aim of this study was to evaluate the effect of including different oilseed grains in the diets of cattle on the qualitative and sensory characteristics and fatty acid profile of burger over a storage period of up to 120 days. The soybean diet increased 30% of ether extract in burgers when compared to the control diet. The inclusion of oilseeds in the bovine diet did not change the n-6/n-3 and hypocholesterolemic/hypercholesterolemic ratio, as well as the cholesterol levels in the burgers. The smallest flavor and aroma note scores were attributed to burgers produced with meat of bovine fed with cottonseed (4.35 and 4.67, respectively). The sunflower diet resulted in smaller lipid oxidation (1.03 mg/kg). The storage period increased lipid oxidation (0.43 and 1.97 mg/kg of malonaldehyde at 0 and 120 days, respectively). The inclusion of oilseeds in the diet of cattle does not change the ratios of fatty acids in burgers, which are important to human health. It is recommended to use soybean and sunflower grains in cattle diets to improve the sensory quality of burgers. A 30-day storage period is recommended to maintain the flavor and juiciness of beef burgers.

The aim of this study was to evaluate the effect of increasing levels of extruded soybean (0, 7.5, 15, 22.5 and 30%) in soybean meal replacement on the diet of Japanese laying quails on biometry of the tibia and femur bones. A total of 180 female quails of the species Coturnix coturnix japonica with approximately 150 days of life standardized by body weight, distributed in galvanized wire measuring 38 cm long × 40 cm wide × 23 cm height were used. The design was completely randomized (CAD), with five treatments and six replicates containing six birds per replicate. The experiment lasted for 84 days, with three cycles of production, with 28 days each cycle. There was no significant effect (p>0.05) of the inclusion of increasing levels of extruded soybean on the biometrics of the tibial and femur bones, nor was there any adverse effect on the Seedor index of these bones, which shows that they remained the same. with good resistance during all production cycles of these birds. It can be concluded that the use of extruded soybean up to 30% does not negatively influence the tibial or femur biometry of Japanese quails or the Seedor index of these bones, which shows that bone strength was not affected by inclusion of this food.

Three main crop straws including corn straw (Zea mays, CS), rice straw (Oryza sativa, RS), and wheat straw (Triticum aestivum, WS), and two forages including alfalfa hay (Medicago sativa, AH) and corn silage (Zea mays, CSil) were analyzed in order to compare their ruminal degradability, indigestible neutral detergent fiber (iNDF), intestinal digestibility (ID), and their total-tract digestibility (TTD) of crude protein (CP), neutral detergent fiber (NDF), and acid detergent fiber (ADF) using both an in situ nylon bag technique and a mobile nylon bag technique. The forage samples were incubated in the rumen for 6, 12, 16, 24, 36, 48, 72, and 288 h, respectively, to determine their ruminal degradability. Prior to intestinal incubation, forage samples were incubated in the rumen for 12 h and 24 h to determine the ruminal degradable content of CP, NDF, and ADF, respectively, and for 288 h to determine their iNDF288 content. Residues from the ruminal undegradable fractions (12 h for CP, 24 h for NDF and ADF) were subsequently inserted into the duodenum through a cannula to determine their intestinal digestible content. Here, the TTD of CP, NDF, and ADF were determined as the ruminal degradable content + intestinal digestible content. The results showed that AH had the highest iNDF2.4 (calculated as acid detergent lignin content × 2.4) and iNDF288 values (379.42 and 473.40 g/kg of NDF), while CS and CSil had the lowest iNDF2.4 values (177.44 and 179.43 g/kg of NDF). The ruminal degradability of CP, NDF, and ADF for CS, RS, and WS were lower than those of AH and Csil during the first 48 h of incubation. The potential degradation fraction of CP, NDF, and ADF for CSil was the highest; CS, RS, and WS were intermediate; and AH was the lowest (p < 0.05). CS, RS, and WS had a lower intestinal digestibility with respect to their rumen undegradable content of NDF (p < 0.05), and lower TTD of CP, NDF, and ADF (p < 0.05) compared to AH and CSil. General regression equations with satisfactory accuracy (R2 ≥ 0.828) were derived to predict iNDF288 and TTD based on their chemical compositions and the ruminal degradation kinetics of different forages. Incorporating this information into rations could improve our ability to optimize main crop straws utilization and milk production.
