“…Higher body weight gain was found in diet with protein bound Lys (Lys from ingredients) as related to diets with free Lys sources (L-Lys HCl and L-Lys sulfate) supplementation. As, lysine has an important role in broiler growth and a sufficient amount of lysine is required to meet that requirement (Brasil et al, 2018). Results are in line with findings of Oliveira et al (2014) reported that body weight gain was significantly higher in protein bound Lys diets as compared to diets with Lys supplementation.…”

The objective of this study was study the protein bound and free lysine (Lys) on production performance in broilers. Two hundred and sixteen (216) day-old broiler chicks were distributed into three treatments, six replicates and 12 birds in each. Three isonitrogenous (CP 22.5%) and isocaloric (ME 3000 Kcal/kg) experimental diets were formulated. In control diet, total digestible Lys (1.20%) was contributed by feed ingredients like soybean meal, canola meal and fish meal. In other two diets, out of 1.2, 0.06 was free Lys that was either contributed by L-Lys Sulfate or L-Lys HCl which were assumed to be 100% digestible. Feed intake was (P≤0.05) lower in birds received free Lys than those reared on bounded Lys. Weight gain and FCR were improved (P≤0.05) in birds received protein bound Lys and free Lys as L-Lys Sulfate than L-Lys HCl. Dressing percentage, liver weight, water holding capacity, pH, cooking loss and blood hematology parameters were not affected by treatments. Production cost per kg live weight was lower in birds received free Lys as L-Lys Sulfate than others treatments. It can be concluded that use of free Lys in the form of L-Lys Sulfate had improved feed efficiency and economics efficiency without having negative effect on meat quality and blood hematology parameters.

“…Indeed, Jasek et al (2018) investigated the effect of a multicarbohydrase-containing α-galactosidase and xylanase on the ileal digestible energy, crude protein, and ileal amino acid digestibility of broilers and found that enzyme supplementation improved the digestibility of individual amino acids, including aspartic acid, threonine, serine, glutamic acid, proline, glycine, alanine, cysteine, valine, methionine, isoleucine, leucine, tyrosine, phenylalanine, lysine, histidine, and tryptophan. In this assumption, among these amino acids, lysine stands out because it comprises ~7.5% of all carcass protein (Sklan and Noy, 2004) and, thus, directly influences carcass parameters (Brasil et al, 2018).…”

The objective of the present study was to evaluate the effects of xylanase and probiotic supplementation on the performance, carcass characteristics, intestinal pH, intestinal viscosity, and ileal microbiota of broiler chickens fed diets containing wheat bran. The study animals were kept in metal cages, and the study was performed using a completely randomized design, with four treatments, six birds per treatment, and six replicates. The four treatments included a control group, a probiotic-supplemented group, a xylanase-supplemented group, and a group that received both xylanase and probiotic supplementation. The diets of all four groups contained wheat bran (50 and 30 g/kg for the starter and grower phases, respectively) and phytase, and at 10 d after hatching, the experimental birds were challenged orally with Eimeria sp commercial vaccine. During the initial phase, supplementation with xylanase, probiotics, or their combination yielded greater weight gains than the control diet; however, considering the period from 10-35 d, the chickens receiving xylanase + probiotic and the diet without the additives showed lower weight gain (2.746 and 2.600 kg, respectively). All the supplemented diets reduced cecum viscosity, and supplementation with probiotic showed a significantly lower pH (6.11). The ileal microbiota was also influenced by xylanase and probiotic supplementation, modulating the frequencies of the genera Lactobacillus and Clostridium. The positive effects of supplementation with xylanase or probiotics alone were similar to those of co-supplementation, and no associative effect was observed.

In recent decades, the availability of sulphur in soil has become a limiting factor compromising plant growth and consequently affecting animal and human feeding. Moringa oleifera L. is known as one of the most useful multipurpose plants. It can be effectively utilized as food supplement and help in the management of nutrient shortage and sulphur metabolism stimulation because of its nutrient and sulphur content. The present experiment was conducted to assess the effect of Moringa leaf powder supplementation on growth performance, biochemical profile and sulphur metabolism stimulation of broiler chicken. A total of fifty-six broiler chicks of 21-day old (Cobb500) were purchased and randomly divided into four groups with two replicates containing seven birds each. Broiler starters were fed with the same starter diet; while at growth stage, four types of diet were formulated: F0 (Moringa 0%), F1 (Moringa 2%), F2 (Moringa 4%) and F3 (Moringa 8%). Chicks were fed twice a day and water was given ad libitum with the experimental diets till completion of the experiment. Collected data were analysed using ANOVA and were statistically significant if p<0.05. Significantly higher body weight was recorded in birds fed with F1 whereas feed conversion ratio was not significantly affected. No significant differences were observed in ash and carbohydrate content of broiler meat due to feed supplementation. The experimental diets did not considerably affect broiler chicken serum parameters, indicating no harmful or deleterious effect. Likening result to control, the consumption of Moringa leaf powder by birds significantly increased the synthesis of protein up to 30% and 38% respectively in the serum and breast meat, glutathione as well as the glutathione S-transferase activity. It may thus be concluded that, the inclusion of Moringa leaf powder in broiler chicken diet increases growth performances and metabolism stimulation through the synthesis of some sulphur compounds.
