THE EFFECTS OF VEGETABLE LECITHIN ON SOME SANGUINE BIOCHEMICAL PARAMETERS AT LACTATING SHEEP AND GOATS

Abstract

From a complex experiment of establishing the effects of lecithin supplemented in
the diet of small ruminants, in this paper we present the influence of lecithin on
some sanguine biochemical parameters at lactating sheep and goat. The researches
were made on a experimental group formed by 5 sheep from łurcana breed and 5
goats from Crapatina breed, which were fed in the first experimental period with a
base ratio (Br) formed by 1.5 kg of hill hay and 0.2 kg concentrate forage mixture,
in the second experimental period the Br was supplemented with 100 g
lecithin/day/animal. At the end of each experimental period were taken blood
samples to establish some biochemical parameters from sanguine serum. The
supplementation of base ration with 100 g lecithin/day/animal at lactating sheep
and goats did not produced significant changes to values of total proteins (TS),
albumin, creatinine, urea and total bilirubins (TB) from sanguine serum. Contrary
to expectation the cholesterol and triglycerides were higher than normal both in
sheep (from 82 mg/dl to 83 mg/dl for cholesterol and from 23 mg/dl to 45 mg/dl for
triglycerides) but specially in goats (from 59 mg/dl to 68 mg/dl for cholesterol and
from 24 mg/dl to 55 mg/dl for triglycerides). Were registered significant increment
of activity of alkaline phosphatase and in γ – GT and a decrease of plasmatic
activity of pancreatic α-amylase both in sheep and goats.
