“…All ingredients showed higher energetic value (P < 0.05) in older birds. Santos et al (9) found similar results in broilers of slow growth rate (Isa Label), with higher AMEn values in broilers 28 to 35 days old than in 10 to 17 days old broilers, evaluating whole corn germ, sorghum, and soybean meal.…”

“…In addition, the endogenous losses also decrease with the advancing age in birds and can directly affect the apparent metabolizable energy values (5) . The best energetic utilization of ingredients and complete rations by older chickens has been described in both fast-growing broilers (6)(7)(8) and slow-growing broilers (9)(10)(11) .…”

The aim of this study was to evaluate bromatological composition and metabolizable energy values of cottonseed meal, rice meal, and wheat bran when provided to slow growth rate broilers at different ages. Energy values of 15- to 25- and 35- to 45-day-old broilers were determined by the total feces collection method using two digestibility bioassays. The birds were distributed in a completely randomized experimental design to evaluate the age effect, with six replicates of 10 chickens each, for each ingredient. Values of apparent metabolizable energy adjusted by nitrogen balance (kcal/kg), for the first and second ages were: 1,255 and 1,564 for cottonseed meal, 3,124 and 3,301 for rice meal, and, 2,211 and 2,383 for wheat bran, respectively. The ingredients showed some variations regarding chemical composition and energy values, which were higher (P < 0.05) in older broiler chickens.

“…Monosaccharides from fermented carbohydrates in the intestine directly stimulate the proliferation of epithelial cells (Roberfroid et al, 2010;Ajuwon, 2016). Intestinal epithelial cells and enzyme activity in the digestive tract are maintained by probiotics, so that stimulates the absorption of the increased nutrients , including feed energy sources (Santos et al, 2015).…”

Lactobacillus plantarum AKK30 inoculum in de Maan Rogosa Sharpe Broth (MRSB) grown on media containing oligosaccharides (inulin or mannan oligosaccharides/MOS) was studied in vitro and in vivo. In vitro assay was conducted to characterize metabolite profiles and its effect on pathogenic bacteria, while in vivo assay was conducted to study the metabolic energy, nitrogen retention, and intestinal morphology of broilers. A total of 24 male broilers-40-day-old (average body weight= 1.725±0.05 kg) strains Cobb-500 were used, where 20 birds were added 1% inoculum L plantarum AKK30 of daily intake and randomly distributed in five treatments and four replications consisted of: A) MRSB + L. plantarum AKK-30 (10⁷ cfu g -1 ); B) MRSB + inulin 0.5% (w v -1 ); C) MRSB + MOS 0.5%(w v -1 ); D) L. plantarum AKK-30 (10⁷ cfu g -1 ) + MRSB + inulin 0.5% (w v -1 ).; and E) L. plantarum AKK-30 (10⁷ cfu g -1 ) + MRSB + MOS 0.5% (w v -1 ), while 4 birds were fasted as endogenous chicken. The results showed that the highest isoleucine and threonine were found in group E. The highest oleic acid and the lowest conjugated linoleic acid (CLA) were observed in all treatments and inoculum did not affect antibacterial activity. The metabolizable energy values and nitrogen retention in group D and E were higher than other treatments (p<0.05). The lowest height of villi was observed in group A (p<0.05). In conclusion, the addition of oligosaccharides inulin or mannan oligosaccharide (MOS) affects the metabolite profiles of Lactobacillus plantarum AKK30 and their synbiotic effects improve intestinal morphology, metabolizable energy, and nitrogen retention in broilers.

Effect of grain particle size on energy values and chemical components of diets for Label Rouge broilers

et al. 2021

This study aimed to determine the apparent metabolizable energy (AME) and nitrogen-corrected AME (AMEn) values as well as the metabolizability coefficients of dry matter, protein, and ether extract of corn, pearl millet, and sorghum in different particle sizes for slow-growing broilers. Two experiments were carried out involving 280 chicks of the Label Rouge® Naked Neck broiler line, with 140 chicks allotted to each experiment in a completely randomized design. Treatments consisted of a reference diet and a test diet (60% reference diet + 40% feedstuff). The feedstuffs were tested and particle size (expressed as geometric mean diameter [GMD, μm] and geometric standard deviation [GSD], respectively) results were 816 and 1.73 for coarsely ground corn, 794 and 1.75 for finely ground corn, 1.517 and 1.92 for pearl millet grain, 760 and 1.63 for finely ground pearl millet (Experiment 1); and 1,866 and 1.86 for whole grain sorghum, 919 and 1.62 for coarsely ground sorghum, and 878 and 1.72 for finely ground sorghum (Experiment 2). A metabolism trial was conducted by using the total excreta collection method to obtain the AME and AMEn values as well as the metabolizability coefficients of dry matter, protein, and ether extract. The energy metabolization coefficient did not differ (P > 0.05) between the grains in the different tested particle sizes. However, there was an improvement in the metabolizability coefficients of dry matter, nitrogen, and ether extract as the particle size of corn was increased. In conclusion, larger grain particle sizes improve the metabolizability of nutrients and energy for slow-growing broilers. Whole-grain sorghum has limited nutritional utilization for slow-growing birds up to 21 days of age.
