Hippophae rhamnoides as novel phytogenic feed additive for broiler chickens at high altitude cold desert

Abstract

Extremes of climate and hypobaric hypoxia cause poor growth performance in broiler chickens at high altitude. The present study examined the potential of Hippophae rhamnoides extract as phytogenic feed additive for broilers reared at 3500 m above mean sea level (MSL). Higher content of phytomolecules were recorded during characterization of the extract. Immunomodulatory activity of extract was observed in chicken lymphocytes through in-vitro studies. Thereafter, for in vivo study, 105 day old Rhode Island Red (RIR) Cross-bred chicks were randomly distributed in to control and treatments T1, T2, T3, T4, T5, and T6 which were supplemented with H. rhamnoides aqueous extract along with basal diet, at level of 100, 150, 200, 300, 400, and 800 mg/kg body weight of chicken, respectively. Among the experimental groups, birds in the T3 group represent the highest body weight. Furthermore, treatment group birds had shown better physio-biochemical indices as compared to control group birds. Interestingly, lower mortality rate due to ascites and coccidiosis was recorded in treatment groups and therefore, higher net return was observed. Hence, present investigation demonstrated the beneficial effect of H. rhamnoides extract (@200 mg/kg) at high altitude and therefore, may be used in formulation of feed additive for poultry ration.

Morphometric, haematological and physio-biochemical characterization of Bactrian (Camelus bactrianus) camel at high altitude

“…Since, camels graze on a hilly valley and plains which are flourishing with various herbal flora and especially seabuckthorne plant leaves. These plants are rich in many flavonoids and alkaloids phytomolecules having antioxidant properties [29]. Therefore, these phytomolecules may have beneficial effects on body metabolism and health of native livestock [29], including double humped camel through modulating body antioxidant status.…”

“…These plants are rich in many flavonoids and alkaloids phytomolecules having antioxidant properties [29]. Therefore, these phytomolecules may have beneficial effects on body metabolism and health of native livestock [29], including double humped camel through modulating body antioxidant status. However, these factors need detailed investigation on how different phytomolecules affect the native camel's health and productivity.…”

Alternative feed ingredients in the finisher diets for sustainable broiler production

“…Livability percentage was then calculated by using the formula ((total number of live birds after the experiment/Initial total number of birds) × 100). The economic efficiency of the dietary inclusion of alternative protein sources was calculated as the total costs needed to obtain one-kilogram BWG according to Kalia et al 12 . The European performance efficiency factor (EPEF) was calculated at the end of the experimental period.…”

Dietary phytogenic mixture for broilers reared under thermoneutral and heat stress conditions

“…Papuc et al, (2009) reported in an in vitro study that sea buckthorn (H. rhamnoides) polyphenolic extract protected the refrigerated meat (beef and pork) against lipid peroxidation. Kalia et al, (2018) reported that H. rhamnoides extract is rich in flavonoids and its inclusion in the diet (200 mg/kg) improved the antioxidant defense level, increasing T-AOC and decreasing the MDA in the plasma of Rhode Island Red Cross-bred chicks reared at high altitude cold dessert. The same authors explained that those results could be attributed to the potentially synergistic effect of phenolic compounds and carotenoids contained.…”
