Standardized ileal digestibility coefficients(SIDC)of nitrogen(N)and amino acids(AA)in two protein sources(soybean meal[SBM]and canola meal[CM])were investigated at six broiler ages(d 7,14,21,28,35,and 42).Two assay diets were formulated to contain either SBM(413 g/kg)or CM(553 g/kg)as the sole dietary AA *** dioxide(5 g/kg)was added as an indigestible marker.A total of 696 male broilers at 1 d old were allotted to 12 replicate cages per age *** assay diet was offered to birds for 4 d prior to the ileal digesta collection on d 7(14 birds/cage),14(12 birds/cage),21(10 birds/cage),28(8 birds/cage),35(8 birds/cage)and 42(6 birds/cage),*** apparent digestibility coefficients were standardized using age-specific basal endogenous AA *** the SBM group,though the SIDC of N tended to be influenced(quadratic;P=0.075)by age,no linear or quadratic response of age effect was observed on the average SIDC of indispensable(IAA)and total AA(TAA).An age effect(quadratic;Pprotein source and *** results demonstrate that age-specific SIDC AA data might need consideration in broiler feed formulations.

This experiment studied the effects of dietary protein sources and levels on the gut health of piglets,p H value,and concentrations of microbial metabolites(ammonia-N,volatile fatty acids [VFA],and polyamines) in the distal colonic and proximal colonic digesta of piglets weaned at 21 d of age.A total of 150 early-weaned piglets were allotted randomly to 5 diets: 1) control diet(CT; 17% CP),2) CT formulated with more soy protein concentrate(SPC19; 19% CP),3) more fish meal(FM19; 19% CP),4) CT formulated with more soy protein concentrate(SPC23; 23% CP),and 5) more fish meal(FM23; 23%CP).Results showed high protein level increased fecal score(P protein sources did not(P > 0.05).The p H value and ammonia-N concentration of digesta in the proximal and distal colon of FM23 were significantly higher(P 0.05).Histamine and spermidine concentrations of FM23 were higher than those of other treatments(P < 0.05).Propionic acid and butyric acid concentrations in the distal colon were higher of FM23 than of FM19(P < 0.05); putrescine,histamine and spermidine were higher of FM23 than of LP and FM19(P < 0.05).It was concluded that high dietary CP content increased microbial metabolites(ammonia-N,histamine,putrescine) in colonic digesta and aggravated piglets' diarrhea.

Organic wastes are one of the greatest challenges that cities face worldwide. In numerous underdeveloped nations, like Cameroon, waste is often disposed of through landfills, composting, or open-air combustion. Unfortunately, the concept of waste sorting and organic waste processing is new to many individuals. This has led to an increase in the amount of organic waste and the costs connected with its management. Consequently, the majority of developing nations have sought out waste management solutions that are more cost-effective. Therefore, it has been determined that the bioconversion of organic wastes by black soldier fly larvae (BSFLs) (Hermetia illucens) into multifunctional prepupae is a viable alternative. Appreciation is given to the employment of the organic waste management approach in developing nations since it is not only environmentally friendly and economically viable, but also provides a means for waste valorisation through the production of diverse resources and potential economic benefits. Studies have proved the usefulness of the insect in controlling organic wastes, but countries such as Cameroon are still unfamiliar with the nuances of this method. Consequently, this timely review examined the performance of the BSFL, specifically in organic waste treatment, as well as the best practices for multiplying them to determine its viability for use in a waste treatment plant, the production of high-quality larvae as a source of protein for livestock, and the production of diesel fuel.
