Effect of different immunoglobulin sources on haematology and serum biochemistry of beetal kids under stall-fed conditions

Abstract

Twenty four beetal kids were assessed through immunoglobulin supplementation from different sources by assessment of haematological profiles and serum biochemistry. The kids were randomly distributed and supplemented through immunoglobulin from four different sources i.e. natural milk (C 0), natural colostrum (C 1), artificial colostrums (C 2) and dam's serum (C 3). C 1 and C 0 acted as positive and negative control, respectively, whereas, C 2 and C 3 acted as treatment groups. Up to five days, kids of C 0 , C 1 and C 2 received the same at 10% of their body weight. Kids of C 3 received their dam's serum at 5ml/day through subcutaneous route. After five days, all kids received milk up to 90 days along with creep feed and green fodder from 15th days onwards. Blood from each kid was collected from jugular vein on day 0, 6th, 15th, 30th, 60th and 90th days for analysis of haematological and biochemical profiles. There was no effect of different Ig sources on different haematological and biochemical profiles except lymphocytes and neutrophils. Though neutrophils and lymphocytes differed significantly (P < 0.05) among groups, they were within normal range. From immunoglobulin point of view artificial colostrum and dam's serum proved to be as equal as natural colostrum. Furthermore, dam's serum may be a good alternative to natural colostrums if not available.

Use of clinic refractometer at farm as a tool to estimate the IgG content in goat colostrum

“…The range of colostrum IgG concentration is wide, it was from 7 to 159 mg/mL (Quigley et al 2013) in the healthy udder of cows, but when inflammation is present, IgG concentration may be affected (Watanabe et al 2017). In addition, the source of immunoglobulins has an effect on the IgG concentration in blood (Rana et al 2016). It is important to note the differences in colostrum composition observed between dairy species (Hernandez-Castellano et al 2016).…”
