Studies on nutritional and economical models under different production system: 2. effect of fatty acid of calcium soap supplementation on physuological response of dairy goats
Abstract: This study aimed to evaluate the effect of dietary supplementation of three types of calcium salts of fatty acids (CSFA) from soybean (SBM), cotton seed (CS) and palm (PM) oils added to the diet of lactating Zaraibi goat does on milk production and blood parameters. Does were allocated to four groups fed basal diet consisted of CFM, berseem hay and bean straw. The supplements were CFM compounded to contain no CSFA supplements (G1, 5% of DM intake from CSFA of SBM oil (G2), CS oil (G) and PM oil. Milk production during suckling (90 d) and milking (120 d) periods, was determined. Blood samples were collected during pre- and post-partum for determination of some biochemicals, enzyme activities and hormonal concentrations in serum Results showed significant differences in milk yield among groups during suckling and milking periods. Serum glucose concentration decreased (P<0.05) in G2 and G3, while urea concentration decreased (P<0.05) in all treatment groups as compared to the control during pre- and post-partum. Concentrations of albumin, glucose, cholesterol and creatinine during pre-partum and those of total protein, albumin, total lipids, cholesterol and creatinine during postpartum were not affected significantly by treatment. Activity of AST, ALT and alkalin phosphatase (ALP) during pre-partum was not affected by treatment. Concentration of T3 was the highest (P<0.05) in G2 and the lowest in G4.
During post-partum, concentration of T3 and T4 was not affected by treatment. Activity of AST was higher (P<0.05) in G2 and G3 than in G1 and G4 Activity of ALP and concentration of T4 were not affected by treatment during pre- and post-partum. There were insignificant differences in litter size (2.50-2.66 kg for all groups). Male: female ratio of horns was nearly equal in G1 G2 and G4 and with more females in G3 (33.3: 66.7 male: female ratio) Dams in G4 showed the highest (P<0.05) proportion of does producing twins (33.3%) and quartet/litter (33.3%), while those in G3 and G1 showed the highest proportion of triples, being 66.6 and 50%, respectively. Kids of G2 showed the highest (P<0.05) viability rate. There were insignificant differences in estradiol and progesterone concentrations in blood serum during post-partum period. It could concluded that, using calcium salt of fatty acid tented to improve does behavior and increase milk yield and its composition than that of control group. Moreover, blood profile pictures and hormones activities showed better with animals fed CSFA supplementation.
