“…Doti et al (2014) argued that a high rate of starch digestion results in a sharp but short increase in blood glucose after feeding, facilitating fat deposition. In contrast, a gradual increase in blood glucose from the digestion of slowly-digestible starch gives rise to a prolonged release of insulin in the blood, resulting in an increased lean deposition (Li et al 2017). In line with our findings, previous studies have demonstrated that other former food sources have no detrimental effects on growth performance in newly weaned pigs in commercial farm conditions.…”

The effect of a diet based on former food products (FFP) as alternative feed ingredients on in vitro and in vivo digestibility of dry matter (DM), pig growth performance, and selected plasma biochemical variables were evaluated. After an adaptation period (7 d), 12 post-weaning piglets (28 days-old) were housed for 16 d in individual pens and assigned to two experimental groups: Control (n ¼ 6), received a standard diet and FFP (n ¼ 6), received a diet in which conventional cereals (wheat, barley, and corn), plasma powder and whey powder, were partially replaced by 30% FFP. During the experiment, stool and blood samples were also collected for DM in vivo digestibility and for plasma biochemical measurements, respectively. The results revealed that both in vitro and in vivo digestibility values were higher (p<.05) for FFP diets compared to the control diets. At the end of the experiment, no differences in BW were observed between groups (p¼.61). ADG and ADFI were not affected by dietary treatment. Conversely, piglets on the FFP diet showed a lower FCR (p<.01). Finally, dietary treatment also affected plasma glucose and urea, which in pigs fed FFPs increased and decreased, respectively. Taken together, these results suggest that the use of FFPs up to a level of 30% in post-weaning diets has no detrimental effects on pig growth performance, although more studies are needed to confirm these results. HIGHLIGHTS CFormer foodstuffs products (FFPs) are valuable alternative feed ingredients. FFPs can partially replace cereal grains in post-weaning piglet's diets without affecting growth performance.

“…Some key calcium signaling pathway genes enriched were AVPR1A (Arginine vasopressin Receptor 1A), CCKAR (Cholecystokinin A), CHRM2 (Cholinergic Receptor Muscarinic 2), EDNRB (Endothelin Receptor Type B), GHRL (Ghrelin and Obestatin Prepropeptide), PROKR1 (Prokineticin Receptor 1), and NMS (Neuromedin-S). Polymorphisms in several of these genes were found to be associated with meat quality and productivity traits [82][83][84].…”

Non-synonymous SNPs and protein coding SNPs within the promoter region of genes (regulatory SNPs) might have a significant effect on carcass traits. Imputed sequence level data of 10,215 Hanwoo bulls, annotated and filtered to include only regulatory SNPs (450,062 SNPs), were used in a genome-wide association study (GWAS) to identify loci associated with backfat thickness (BFT), carcass weight (CWT), eye muscle area (EMA), and marbling score (MS). A total of 15, 176, and 1 SNPs were found to be significantly associated (p < 1.11 × 10 −7 ) with BFT, CWT, and EMA, respectively. The significant loci were BTA4 (CWT), BTA6 (CWT), BTA14 (CWT and EMA), and BTA19 (BFT). BayesR estimated that 1.1%~1.9% of the SNPs contributed to more than 0.01% of the phenotypic variance. So, the GWAS was complemented by a gene-set enrichment (GSEA) and protein-protein interaction network (PPIN) analysis in identifying the pathways affecting carcass traits. At p < 0.005 (~2,261 SNPs), 25 GO and 18 KEGG categories, including calcium signaling, cell proliferation, and folate biosynthesis, were found to be enriched through GSEA. The PPIN analysis showed enrichment for 81 candidate genes involved in various pathways, including the PI3K-AKT, calcium, and FoxO signaling pathways. Our finding provides insight into the effects of regulatory SNPs on carcass traits.Genes 2020, 11, 316 2 of 22 and eye muscle area (EMA) [4]. Though substantial improvement in carcass and meat quality have been achieved, due to market requirement for higher quality, and for improving the economic value of Hanwoo, continuous improvement of economically important trait is required [5,6]. A genome-wide association study (GWAS) is an affordable and powerful tool to discover candidate genes and loci associated with quantitative traits [7]. GWASs in livestock, including in Hanwoo [8][9][10][11], have resulted in remarkable insights into the genetic architecture of carcass traits. Genetic variation in complex traits such as carcass and meat quality traits are, however, due to the contribution of many mutations with small effects [1,12] (polygenic effect). Though some of these mutations have been successfully identified through GWASs, the high significance thresholds required to correct for the multiple testing problem results in the identification of only SNPs with a large effect size [7,12]. Further, a GWAS does not make use of the fact that genes work together in a network, and multi-allelic QTL might not be captured due to the bi-allelic nature of SNPs [13]. Moreover, epistasis is an important genetic component underlying phenotypic variation that also accounts for missing heritability [14]. Therefore, a GWAS alone might result in only limited understanding of the nature of complex traits [13]. Suggested solutions to overcome this limitation and understand the genetic complexities regulating complex traits are to complement a GWAS with gene-set enrichment, a protein-protein interaction network (PPIN), and pathway analyses [15][16][17][18]. In GSEA and pathway analysis, a g...

“…The regulatory effects of MLM on lipid metabolism have been studied in several animal species. In pigs, the inclusion of 10% mulberry leaf in their diet led to a lower percentage of leaf lard and lower back-fat thickness (Li et al, 2012). In poultry, mulberry leaves were found to regulate the metabolic activity of lipids, with concentrations of 3% MLM being the most effective in decreasing total cholesterol and LDL-cholesterol, while at the same time increasing HDLcholesterol and glucose concentrations (Park et al, 2012).…”

Availability of feed crops for animal production is decreasing, creating a need to identify alternative food sources. With their high protein content, mulberry leaves are a likely candidate for feed supplementation and have been trialed on pigs and chickens, but little is known about their effect as a feed supplement on geese. Here, we determine the nutritive value of mulberry leaf meal (MLM), measure the digestibility of energy and amino acid of MLM in male Sichuan white geese, and evaluate the performance of these geese fed an MLM-supplemented diet. The composition of MLM was as follows: gross energy 4.94 Mcal/kg, crude protein 18.81%, ether extract 11.65%, crude fiber 12.45%, calcium 2.46%, phosphorous 0.24% and amino acids 0.26-1.92% (all % on a dry matter basis). Using the emptying then force-feeding method on 24 geese aged 194 days, we measured the apparent metabolizable energy of MLM as 1.58 Mcal/kg (on a dry matter basis), and the true total tract digestibility of the amino acids in MLM as 50.54-79.98%. We then randomly allocated a further 210 geese aged 35 days to one of five dietary treatments (control diet alone or supplemented with 4%, 8%, 12% or 16% MLM). Each treatment contained six replicate pens of seven birds per pen, and birds were maintained on their treatment until 70 days of age. Geese fed diets containing MLM exhibited lower weight gains, elevated feed consumption and an increased feed to gain ratio (P＜0.05) compared with geese fed the control diet. Moreover, geese fed diets supplemented with MLM all experienced diarrhea, reduced amounts of subcutaneous fat and lower percentages of skin and abdominal fat (P＜0.05) compared with control geese. In conclusion, MLM should be used with caution as a feed supplement for geese.
