Effect of extra-concentrate and probiotics supplementation in periparturient goat on its milk composition and somatic cell count

Abstract

Present study was conducted to study the effect of extra concentrate supplementation with or without
probiotics on milk composition and somatic cell count of goatsduring two months of periparturient period.
Twenty four pregnant healthy Boar x local cross dose in the last month of gestation (day 120) were
selected randomly and allotted to 4 groups (T1, T2, T3 and T4) of six animals. The dose were maintained
under stall feeding conditions and offered a daily ration consisting of oats hay @ 1.2 kg/head/day and
commercial pelleted feed @ 577.5 g/head/day. Dose in treatment groups T1 were offered normal daily
ration without supplementation. In T2 group were offered normal ration and extra concentrate @ 150 gram
/head/day, T3 group were offered normal ratio and extra concentrate @ 150 gram/head/day with probiotic
(Saccharomyces cerevisiae x1010 CFU) @ 2.5 gram/head/day and in T4 groups were offered normal ratio
and extra concentrate 150g + probiotic (Saccharomyces cerevisiae x1010 CFU) @ 4 gram/head/day. Milk
samples were collected in the morning of 20th day of lactation and were analyzed for fat, protein, solidnot-
fat, total solids percent and somatic cell count using standard procedures. There was non-significant
differences (p<0.05) infat, protein, solid-not-fatand total solids percent among different treatment groups.
However, there was a significant difference (p<0.05) in SCC (103 /ml) of T3 and T4 group as compares to
T1 (control) and T2 treatment group. Lowest SCC was found in T3 treatment group as 105.83±3.14 x103
/ml and highest in T1 (control) group as 128.66±0.80 x103 /ml.
