Omega 3 polyunsaturated fatty acid (n–3 PUFA)
especially eicosa pentaenoic acid (EPA) and docosa
hexaenoic acid (DHA) can play a very important role in
reducing the cardio vascular disorders. Fish oil obtained from
Indian oil sardine is an excellent source of these fatty acids
(Ambasankar and Balakrishnan 2006). Inclusion of these n–
3 fatty acids in ruminant diet results in extensive ruminal
biohydrogenation and can greatly disrupt fermentation in the
rumen causing reduced digestibility of non-lipid energy
sources especially the fibre portion of the diet. In this context,
ways and means to prevent their degradation in the rumen,
but get delivered post ruminally for enhancing effective
transfer into the milk and meat is an important step. The
method of protecting fat/oil supplementation from rumen
degradation varies according to the source. Hence, this
research work was carried out to examine the influence of
various forms of protected sardine oil in complete diet on
rumen fermentation and nutrient digestibility.
Sardine fish oil was collected from 5 sardine oil-producing
units in the West Coast of India and was protected from
ruminal degradation by 3 methods, viz. calcium soap of
sardine oil, formaldehyde treated protein encapsulated
sardine oil (FTPE), and fatty acyl amide of sardine oil.
Calcium soaps of sardine oil were prepared by precipitation
method (Sampelayo et al. 2002), FTPE of sardine oil as per
Sutton et al. (1983), and the fatty acyl amide of sardine oil
was synthesized as per Loor et al. (2002).
Four complete diets were formulated with 50% fodder
(hybrid Pennisetum glaucum × Pennisetum purpureum), 27%
rice bran, 20% maize and 3% any one of fat sources, viz.
sardine oil or calcium soap of sardine oil or FTPE sardine
oil or fatty acyl amide of sardine oil. Mineral and vitamin
mixtures were added to provide adequate level
