Effect of feeding oak leaves (Quercus semecarpifolia vs Quercus leucotricophora) on nutrient utilization, growth performance and gastrointestinal nematodes of goats in temperate sub Himalayas

Effect of oak (Quercus persica) acorn level on apparent digestibility, ruminal fermentation, nitrogen balance and urinary purine derivatives in pregnant goats

“…() studies, DMI increased by inclusion of oak leaves. Our observation about faecal N excretion was comparable to others, who found that higher level of OA (Aghamohamadi et al., ; Al Jassim et al., ) or oak leaves (Raju et al., ; Sharma et al., ) increased faecal N excretion. Tannins of OA interact with dietary CP and form indigestible complex of tannin protein, so faecal N excretion increases (Abarghuei et al., ; Patra & Saxena, ).…”

“…As shown in Table , DMI was lower in goats fed OA‐containing diets in relation to those fed the C diet, but in Raju et al. () and Sharma et al. () studies, DMI increased by inclusion of oak leaves.…”

“…For example, Raju et al. () and Sharma et al. () reported higher N intake in growing goats or calves fed diets containing oak leaves respectively, whereas Al Jassim et al.…”

Effect of Feeding Oak (Quercus leucotrichophora) Leaves as Alternative Control of Gastro Intestinal Nematode Infection of Goat in Kumaon Hills

“…The higher organic matter intake in oak leaves fed group of animals was attributed to higher level of OM along with higher DM intake through oak leaves. In consistent with the present findings, dry matter intake was reported to be higher in goats fed on Q.leucotricophora (Raju et al, 2015) and cattle fed on Q.leucotricophora based diet (Paswan andSahoo, 2012 andSharma et al,2008). Higher voluntary intake of moderate (1-4% CT) level of CT containing diets was reported by many workers (Dey et al, 2008).…”

“…Oak leave (Quercus leucotrichophora) is the dominant, climax tree species and most abundantly available throughout the year in the moist temperate forests of the Indian Himalayan region (Singh et al, 1996) and forms the bulk of livestock feed during the critical forage scarcity period of winters. Q. leucotrichophora contain moderate level of CT (3-4%) and shows positive effect on voluntary feed intake, nutrient utilization, live weight gain in animals and reduces the GI nematode load in kids (Raju et al, 2015). Condensed tannin binding agent polyethylene glycol (PEG) has ability to neutralize CT by displacing protein-tannin complexes, as a consequence of CT interact more strongly with PEG than they do with protein.…”
