Replacement value of some tree fodders

Effect of Partial replacement of NXB Grass with Glyricidia leaves on Milk Production and composition
in Cows presented below:

Conc + NXB grass + 15%
Treatment Conc + NXB grass replacement of grass with
Glyricidia sepium leaves
Av. Milk yield (l/d ) 6.72 6.90

Milk Fat % 4.31 4.28
SNF % 8.21 8.02

Milk Protein% 3.09 3.13
Leaf meal based (50% L.Leucocephala + 50 % Glyricidia sepium ) concentrate feed was reported not
to significantly affect the growth rate in Sheep and resulted in 17% decrease in the feed cost compared to
conventional concentrate feed .(Annon, 2018).

Gliricidia sepium harvested from silvipasture system was reported to replace 15 % of green fodder in
lactating crossbred cows with marginal increase in milk yield and can hold 14 cows per year per hectare
without any adverse effect on its milk yield and composition ( Gunasekaran et al.,2017 ).

Limitations to use forage Trees as sole feed
Some tree legumes contain Anti-nutritional factors which adversely affect their feeding value.

Tree fodder Anti-nutritional factors
Leucocephala Genus. Non-protein Amino acids-Mimosine

Acacia Sp. Flouro acetic Acid

Gastrolobium Sp.
Myoporum Sp. Terpinoids and Steroids

Lantana camara Triterpenoid Lantadens
Several Tropical tree fodders Phenolics
