Effect of multiple births on Jamunapari goat milk quality under field and farm rearing conditions

Abstract

Milk composition of mammalian species varies widely with reference to genetic, physiological, nutritional factors and environmental conditions. Milk samples were collected from Jakhrana goat under the farm and field rearing condition. Field samples were collected from different villages. A total of 736 milk samples were collected from field and farm rearing condition 191 single (field 42 and farm 149), twins 480 (field 56 and farm 424) and triplets 65 (field 07 and farm 58) milk samples. The results laid down in Table indicated that the specific gravity in the milk of Jakhrana goat breed under field and farm rearing conditions in single, twins and triplets birth was found to be 1.0304±0.00042 and 1.0310±0.00035, 1.0294±0.00036 and 1.0306±0.0004 and 1.0280±0.00038 and 1.0296±0.00038, respectively. Fat percentage in the milk of Jakhrana goat breed under field and farm rearing conditions in single, twins and triplets birth was 4.37±0.049 and 4.52±0.048, 4.58±0.043 and 4.69±0.044 and 4.70±0.045 and 4.86±0.045, respectively. Protein percentage in the milk of Jakhrana goat breed under field and farm rearing conditions in single, twins, and triplets 3.39±0.026 and 3.25±0.033, 3.32±0.029 and 3.20±0.035 and 3.28±0.028 and 3.12±0.038, respectively. Lactose percentage in the milk of Jakhrana goat breed under field and farm rearing samples in single, twins and triplets births was 4.41±0.020 and 4.36±0.012, 4.50±0.012 and 4.41±0.010 and 4.56±0.015 and 4.49±0.013, respectively. The results laid down in Table indicated that the ash percentage in the milk of Jakhrana goat breed under field and farm rearing conditions in single, twins, and triple birth was 0.76±0.0070 and 0.74±0.0080, 078±0.0072 and 0.76±0.013 and 0.80±0.0079 and 0.78±0.011 respectively. The effect of multiple births on total solid was highly significant at 1% level of significance. Multiple birth effect on solids-not-fat content was significant in all births milk samples under field and farm rearing conditions at 5% level of significance. Multiple births had conspicuous effects on milk quality of goats under study.
