Dietary Grape (Vitis vinifera) Seed Powder and Zn–Gly Chelate Complex for Mitigating Heat Stress in Broiler Chickens: Growth Parameters, Malondialdehyde, Paraoxonase-1, and Antibody Titer

Abstract

A total of 300 day old broiler chicks (Hubbard) were assigned to 30 floor pens (10 birds per pen) under cyclic heat stress. Three diets including a control, as well as two levels of grape seed powder (GSP) and zinc (OZ) at the rates of 2.5 g/kg GSP + 50 mg/kg OZ and 5 g/kg GSP + 50 mg/kg OZ, were supplied to the broilers for 35 days. According to the results, broiler feed intake improved (p < 0.05) in GSP + OZ groups from 3–5 weeks and on an overall basis compared to the control diet. Body weight increased (p < 0.05) in GSP-5 + OZ-50 during weeks 2–5 and on an overall basis. The findings indicated that feed conversion ratio (FCR) decreased (p < 0.05) during week 5 in broilers supplemented with GSP-5 + OZ-50. The antibody titer (HI) against Newcastle disease (ND) was higher (p < 0.05) in GSP + OZ groups compared to control treatment. The value of malondialdehyde (MDA) decreased (p < 0.05) under GSP + OZ diets compared to control. Moreover, paraoxonase (PON1) was higher (p < 0.05) in GSP + OZ groups compared to untreated broilers. In conclusion, GSP + OZ positively supported growth traits, reduced MDA, and augmented PON1 and HI titer against ND in broilers exposed to heat stress.

Prospects of organic acids as safe alternative to antibiotics in broiler chickens diet

“…Several feed additives have been proposed such as probiotic (Khan and Naz 2013;Khan et al2013aKhan et al , b, 2014aAlam et al 2020;Shah et al 2020), prebiotics (Chand et al2016(Chand et al , 2019Tufail et al 2019;Haq et al 2020), enzymes (Abd El-Hack et al 2018;Sultan et al 2019;Alam et al 2020;Jabbar et al 2021a, b), and herbs (Khan et al 2012a, b, c, d;Mushtaq et al 2013;Dhama et al 2014;Alzawqari et al 2016;Hafeez et al 2020a, b, c;Ahmad et al 2020;Chand et al 2021;Israr et al 2021;Khan et al 2021a, b;Shuaib et al 2021a, b), which have been reported in poultry (Fig. 1) and illustrated by Gadde et al (2017).…”

Potential Applications of Moringa oleifera in Poultry Health and Production as Alternative to Antibiotics: A Review

“…The banning of antibiotics as growth promoters, which has triggered research into alternative to antibiotics, such as probiotics [ 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ], prebiotics [ 11 , 12 , 13 , 14 ], enzymes [ 15 , 16 , 17 , 18 ], organic acids [ 19 , 20 ], herbs [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 ] and other compounds [ 37 , 38 ], has been reported in poultry production ( Figure 1 ). Researchers are developing phytogenics for usage in chickens with many advantages, such as increased feed efficiency, improved immunological status, and improved gastrointestinal health, in addition to others [ 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 ].…”

“…Moreover, it was found that feeding of grape seed powder in broilers positively ameliorated the negative effects of E. tenella infection on growth performance, lesion score and oocysts shedding [ 46 ]. Additionally, grape seed improved growth performance, antioxidant status and immune response in broilers under heat stress conditions [ 47 ].…”
