“…In addition, protease supplementation significantly (p < 0.05 -< 0.005) increased the rates of digestion of 12 of the 16 amino acids assessed. Moreover, as proposed by Liu and Selle [22], it is probable digestion rates of amino acids were more indicative of broiler performance than static amino acid digestibility coefficients.…”

“…One possibility is that retarded starch digestion rates provide a greater supply of glucose to the lower small intestine which spares amino acids from catabolism for energy to meet the gut mucosa's requirements thereby permitting the entry of amino acids into the systemic circulation to become available for protein deposition [22]. Based on an in vitro starch digestion evaluation in various cereal grains, Giuberti, et al [23] reported that sorghum had the least rapidly digestible starch (119 g/kg), potential digestible starch (70.4 g/100 g dry starch) and the highest resistant starch (275 g/kg).…”

“…Given the importance placed on starch-protein interactions in sorghum specifically [43], and in general [24], this is only complicated by the likelihood that the two impacts are interdependent. There is the real possibility SMBS modifies both starch and protein digestive dynamics to benefit energy utilisation in broiler chickens [22]. It seems likely that SMBS responses with certain grain sorghum varieties will be more pronounced than others.…”

“…Liu and Selle [22] proposed the provision of either rapidly digestible protein or slowly digestible starch will enhance bird performance and that the protein digestion rate may be more important than starch in this reciprocal or bilateral relationship. Compared to other grains, sorghum has relatively slower starch digestion rate [23].…”

Grain Sorghum: A Conundrum for Chicken-Meat Production

Abstract:The inclusion of grain sorghum in diets for broiler chickens is quite common; however, under Australian conditions, the utilisation of starch/energy by birds offered sorghum-based diets appears inadequate. Various factors inherent in sorghum, including kafirin, phenolic compounds and phytate, may limit energy utilisation. The recent quantification of kafirin, the dominant protein fraction in sorghum, has allowed its nutritional significance to be assessed. This is important as indirect evidence suggests that kafirin concentrations in local sorghums are increasing as an unintended consequence of breeding programs. Presently, Australian sorghums do not contain condensed tannin but, from analyses and assessments of other polyphenolic compounds and phenolic acids, "non-tannin" phenols appear to be negative influences. Anecdotally, white sorghums are considered to be superior to red varieties thus the fact that polyphenolic pigments are responsible for the "redness" of sorghum assumes relevance. Inclusions of sulphite reducing agents in broiler diets have generated promising responses but seem dependent on sorghum properties. Preliminary studies have shown the possibilities of using rapid visco-analyser (RVA) starch pasting OPEN ACCESSAgriculture 2015, 5 1225 profiles, promatest protein solubilities and grain textures to indicate sorghum quality and further studies are required to confirm these hypotheses. These assessments may indicate which sorghums will best respond to reducing agents such as sodium metabisulphite. Finally, the usually modest responses of broilers to exogenous feed enzyme inclusions in sorghum-based are considered in this review.

“…The provision of animal feed without considering the quality and quantity will result in the sub-optimal growth and productivity of the livestock. The main nutrients needed in ration of laying hens are metabolizable energy, crude protein, amino-acids, macro-elements, trace elements, vitamins, and essential fatty acids (Jeroch et al, 2011;Liu et al, 2015). Feed provided adequately, both in quality and in quantity, will significantly help in improving the productivity of livestock.…”

Feed plays an important role in determining the success of livestock businesses and also as a significant cost factor. Feed contributes 60%-80% of the total production costs. The types of feed could have different effects on the cost, efficiency, and productivity of livestock business. Some laying-hen farmers in Blitar District use two kinds of feed, semi self-mixed feed, and total self-mixed feed. This study was conducted to compare the use of two types of feed on the net revenue of laying hen farmers in Blitar Regency. The research used the survey method. The sample in this research consisted of 100 laying-hen farmers in Blitar Regency, 50 of them used semi self-mixing feed and the rest used total self-mixing feed. Data were collected from several laying hen farms in Blitar Regency with a survey method. All data were then analyzed both qualitatively and quantitatively. The average feed price of semi self-mixed feed and total self-mixed feeds were IDR 5,143.38 and IDR 4,854.91 per kg, respectively. The results showed that the feed price, cost of medication/vaccine, the amount of feed, and egg production for semi self-mixed feed farmers had significant effects on the net revenue of the farmer (p<0.05), with the average net revenue being IDR 12,785,471.68 per 1,000 birds/period. Whereas for total self-mixed feed, the medication/vaccine cost and feed amount had significant effects on the net revenue of the farmer (p<0.05), with the average net revenue being IDR 18,467,373.76 per 1,000 birds/period. As a conclusion, the total self-mixed feed showed more optimal net revenue of laying hen than semi selfmixed feed.
