“…These results are in agreement with previous studies reporting that the growth performance of broilers fed 1 to 3% low CP diets was unaffected ( Salah, 2016 ; Van Harn et al, 2019 ). On the other hands, 0.02 to 0.2% low essential amino acid such as lysine, methionine, tryptophan, threonine and arginine and/or 1.6% low ME in diets caused poor BWG and FCR compared to control diets ( Lin Law et al, 2019 ; Maqsood et al, 2022 ). Moreover, supplementation of exogenous protease to NC diets did not significantly affect growth performance, but numerically improved growth performance including BWG and FCR compared with those of NC groups in the current study.…”

“…Also, this discrepancy might be due to the difference of basal diets, used protease, and dosage of protease between this study and other studies. Other researchers asserted that increase of BWG and FCR could be attributed to better nutrient digestibility rather than FI ( Rada et al, 2013 ; Lin Law et al, 2019 ; Maqsood et al, 2022 ).…”

“…Abdominal fat is an important indicator of fat deposition in broilers; excessive fat deposition is undesirable as it reduces feed efficiency and meat quality and increases production and health costs [ 23 , 24 , 25 ]. Previous entries in the literature have reported that higher Lys levels in the diet could help reduce the percentage of abdominal fat in broilers [ 10 ]. Similarly, this study also found that increasing dLys levels in the diet could reduce the percentage of abdominal fats of broilers fed with different dietary starch sources.…”

“…At present, researchers have reported inconsistent results regarding the effect of dietary Lys on abdominal fat deposition in broilers. Maqsood et al [ 10 ] believed that increasing dietary Lys levels could reduce the generation of abdominal fat in broilers. Tian et al [ 11 ] found that a lack of dietary Lys can lead to a reduction in abdominal fat in broilers.…”

This study investigated the effects of digestible lysine (dLys) in different dietary starch sources on liver lipid metabolism and breast muscle protein metabolism in broiler chickens. The experimental design was a 3 × 3 two-factor completely randomized design. A total of 702 one-day-old male Arbor Acres Plus broilers were randomly divided into nine treatments of six replicate cages with thirteen birds each. The treatments consisted of three different starch sources (corn, cassava and waxy corn) with three different dLys levels (1.08%, 1.20% and 1.32%). The trial lasted from 1 to 21 days. Carcass traits, serum metabolites, breast muscle protein and liver lipid metabolism were evaluated. A significant interaction effect (p < 0.05) for dietary starch sources and dLys levels was noted in the percentage of abdominal fat and gene expression related to breast muscle protein metabolism throughout the experimental period. The waxy corn starch diet and a 1.08% dLys level in the diet increased both the percentage of abdominal fat (p < 0.01) and blood total cholesterol (p < 0.05) in the broilers. The waxy corn starch diet significantly upregulated the mRNA expressions of Eif4E, AMPK, FABP1, ACC and CPT1 (p < 0.05). The 1.32% dLys level significantly upregulated the mRNA expressions of mTOR, S6K1, Eif4E, AMPK and PPARα (p < 0.05) and significantly downregulated the mRNA expressions of MuRF and Atrogin-1 (p < 0.05). In summary, the waxy corn starch diet resulted in significantly higher expression levels of fat-synthesis-related genes than lipolysis-related genes, leading to abdominal fat deposition in broilers. Increasing the level of dLys in the diet increased the protein content in muscle by promoting protein synthesis and inhibiting protein degradation and also promoted the expression of lipolysis-related genes, thereby degrading the generation of abdominal fat in broilers. Our findings signify that increasing the dLys level to 1.32% when using the waxy corn starch diet could improve carcass traits.

“…Pakistan is the 11 th largest poultry producer in the world, producing about 1.70 million tons of white meat annually, which is increasing yearly (Ali et al, 2019). The challenging issue in broiler production units is formulating the least cost ration, which ensures 70% of total production cost (Maqsood et al, 2022). The foremost contest for poultry industrialists is to acquire maximum performance while coping with the mortality in broilers.…”

Probiotics, prebiotics, and immunomodulators like β-glucan have become popular feed additives. Thus, this study examined the effects of a β-glucan product fortified with dietary biomaterials (fats, proteins, and minerals) on broiler chicks' growth, carcass features, immunological response, white blood cell (WBC) count, and viable count (number of living cells) of lactobacilli. Day-old Ross-308 (n=250) were randomly assigned to 1 of 5 dietary treatments; A= basal diet, B= basal diet + 40 mg/kg of avilamycin, C= basal diet + 250 g/ton β-glucan product, D= basal diet + 500 g/ton β-glucan product, and E= basal diet + 750 g/ton β-glucan product. The starter diet was administered from days 1 to 14, the grower diet from days 15 to 21, and the finisher diet from days 22 to 35. Each treatment had 5 repetitions of 10 birds. On days 7 and 20, all birds were eye-drop inoculated against the Newcastle disease (ND) vaccine. Three chickens from each replication of all treatments were slaughtered on day 35 to examine carcass features and collect ileal digesta. White blood cell and viable lactobacilli counts at the end of the trial showed the effect of β-glucan supplementation. Throughout the trial, β-glucan administration did not increase average daily weight gain. The treatments did not change WBC or viable count; however, lactobacilli count increased (p≤0.05) in treatment group E. Treatment E increased (p≤0.05) ND-vaccination antibody-titers but did not affect immunological organ development. Treatment diet E (base diet +750 mg/t β-glucan product) improved broiler immunity and gut microbiota. In conclusion, the addition of β-glucan to broiler feed enhanced the beneficial gut flora, particularly Lactobacilli and immune response, and may serve as an alternative to antibiotics.
