“…However, guar bean contains some anti-nutritional factors like trypsin inhibitor and a galactomannan (guar gum) which affect feed conversion ratio and growth performance in broilers (Saxena and Pradhan, 1974). Diets supplemented with guar bean increases intestinal viscosity due to β-galactomannan leading to reduced nutrient digestibility especially in a day old chickens (Lee et al, 2003;Abu Hafsa et al, 2017). This increase in the intestinal viscosity has also a negative effect on passage rate resulting in poor feed intake (Yasar, 2003).…”

| Guar is a very important legume crop in arid areas of Indian sub-continent. Over the world, India is known as the biggest producer of guar bean by contributing around 90% of the total production. Guar meal is defined as a guar gum by-product which has about 450 gram protein per kilogram. In spite having high protein content, guar meal is not known on a commercial scale but it has received substantial attention for animal feedstuffs. Trypsin inhibitors are the main anti-nutritive factor present in guar; however, these can be ameliorated with the uses of enzymes and heat treatment. Fluctuations in market prices of essential feed ingredients motivated poultry nutritionist to look for alternative valuable replacements for certain feeds. Based on the promising findings of guar meal inclusion in diets, it might be an acceptable feed ingredient in poultry feed. Guar meal can be fed up to 100 g/kg diet without adverse effects on poultry performance. Higher level of guar meal at150 g/kg can be detrimental for broiler and layer birds. Because of increasing the availability of guar beans, opportunities have been expanded for using guar meal as a partial alternative for soybean meal (SBM).The inclusion of guar meal in poultry diets canbe maximized by the addition of some feed additives such as β-mannanases. The present review article presents thatnutritional values of protein and amino acids of guar meal is similar to the SBM and seems to be an attractive feed ingredient in the poultry industry.

“…However, GM contains anti‐nutritional factors such as galactomannan (residual guar gum; approximately 18–20% of DM), trypsin inhibitor and saponins, which affect nutrient digestibility, feed conversion ratio (FCR) and the growth performance of poultry. β ‐galactomannan of GM causes reduction in nutrient digestibility . Saponins present in guar meal also tend to form complex with protein, thus reducing the availability of protein.…”

BACKGROUND The present study evaluated the potential of increasing dietary levels of the most limiting amino acids such as total sulfur amino acids (TSAA) with respect to mitigating the adverse effects of the inclusion of guar meal (GM) in the diet of WL layers on egg production, feed efficiency and egg weight. In total, 4928 WL (Lohmann L) hens (32 week of age) were randomly allotted to eight treatments with seven replicates of 88 birds. The dietary treatments were a set of four maize–soybean meal based diets containing four graded concentrations of TSAA (5.85, 6.18, 6.51 and 6.84 g kg−1) and another set of four diets containing 100 g kg−1 guar meal (GM) with similar concentrations of TSAA. RESULTS The inclusion of 100 g kg−1 GM in the diet caused a 20%, 23%, 35.5% and 6.7% reduction in egg production, daily egg mass, feed efficiency and egg weight, respectively, when the diet contained 5.85 g kg−1 TSAA. Increasing TSAA levels in GM groups reduced the adverse effects on egg production and feed efficiency 50%, with no effect on egg weight. The TSAA requirement of WL birds fed 10% GM was estimated as 6.28–7.39 g kg−1 diet at different ages. CONCLUSION Increasing dietary TSAA to 7.39, 6.28, 6.53 and 6.37 g kg−1 or dTSAA (digestible TSAA) to 6.53, 5.32, 5.80 and 5.63 g kg−1 during 33–36, 37–40, 41–44 and 45–48 weeks of age, respectively, may be an effective and practical strategy for reducing the adverse effects of inclusion of 100 g kg−1 GM in the diet of WL layers. © 2018 Society of Chemical Industry

“…In earlier paper [19] dietary polyphenols did not significantly affect ASAT and ALAT, however, the researchers did not performed exact chemical identification of the bioactive components. In the composition used in our experiment, the coniferyl alcohol which possesses cytotoxicity [20] is high in level and can affect hepatic cells, as follows from ASAT and ALAT indicators in groups II and III.…”

A b s t r a c tTo date, numerous studies are focused on searching for alternatives to antibiotics with similar antimicrobial and growth-stimulating effects that do not cause bacterial resistance and potential side effects for animals. Promising phytogenic compounds have been also recognized as potential alternatives to antibiotics in feeds. One of the problems of phytogenic compound use is the unstable chemical composition of plant extracts, depending on the conditions of growth, distribution area and other factors, so the question arises of extracting some substances with the known properties or designing their compositions. In this paper, it has been shown for the first time that a dietary composition of biologically active substances of Quercus cortex helps to maintain productivity and improves the immunomodulating state of Smena 8 poultry cross broilers. In our experiment, a composition of substances (CS) extracted from Quercus cortex and chemically synthesized («Acros Organics B.V.B.A.», Belgium) was used, including 2-n-propylresorcinol (98 %, AVH27024); 4-hydroxy-3methoxybenzaldehyde (99 %, AC14082-1000); 7-hydroxycoumarin (99 %, AC12111-0250); 3,4,5trimethoxyphenol (98.5 %, AC18914-0050); scopoletin (95 %, AC30290-0010); coniferyl alcohol (98 %, AL22373-5) with a confirmed anti-QS effect. A total of 120 broiler chickens aged 7 days were divided into 4 groups (n = 30) by analogue method. Control group was fed with the basic diet (BD). BD + CS 1 (1 ml/kg of live weight), BD + CS 2 (2 ml/kg of lw), and BD + CS 3 (3 ml/kg lw) were used for group 1, group 2, and group 3, respectively. In the experimental groups, as compared to the control, the number of blood leukocytes increased by 19.2-28.5 % (P  0.05), blood lymphocytes were higher by 24.4, 36.2 % (P  0.05) and 44.0 % (P  0.05), blood monocytes were higher by 23.5, 23.5 and 29.4 % (Р  0.05), and blood granulocyte counts were higher by 12.3 % (Р  0.05), 5.7 and 9.5 %. The blood ALT activity in the group 2 and group 3 exceeded the control value by 13.2 % (P  0.05). The level of GGT tended to decrease in the group 2 and group 3, along with a significant decrease in LDH by 17.6-22.5 % (P  0.05). The intake of the CS as a feed additive was accompanied by an increase in blood SOD levels in the test groups, the highest concentration being observed in the group 1 (95.3 %). The catalase indices had similar patterns. Dietary composition of biologically active substances promoted a 16.4 % increase (P  0.05) in blood -lysine levels in the group 1. Within 4 weeks, the dietary CSs led to an increase in the live weight of the poultry of the group 2 and groups 3 by 12.6-15.0 % (P  0.05) when compared to the group 1. In the group 1, the birds grew more rapidly with a 100 % survival rate of the herd, in contrast to the remaining groups with the survival index of 71 to 85 %. These contributed to an insignificant increase in the bird live weight at the end of the experiment (day 42) by 1.9 % (P  0.05) compared to the control group. Thus, feeding broiler chickens with...
