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

Abstract

The study was conducted at the Central Institute for Research on Goats, Makhdoom, Mathura; under the division nutrition feed resources and products technology for the study of farm rearing condition. A total of 479 milk samples were collected from field and farm rearing condition 222 single (field 28 and farm 194), twins 230 (field 66 and farm 164) and triplets 27 (field 08 and farm 19) milk samples. The overall average calcium content of all above samples in all rearing and births was 0.1455±0.0019 per cent. Phosphorus content was significantly greater in farm samples than field rearing samples in all multiple births. Potassium percentage in the milk of Jamunapari goat breed under field and farm rearing conditions in single, twins and triplets birth was found to be 0.113±0.0008 and 0.113±0.0008, 0.111±0.0007 and 0.111±0.0008 and 0.107±0.0008 and 0.109±0.0008 respectively. The highest magnesium, chloride and selenium content were observed in single birth samples under field as well as farm rearing samples. Multiple births had conspicuous effects on milk quality of goats under study.

Embryonic differentiation of intestine in Indian goats (Capra hircus)

“…Approximate age of the embryos (up to 30 days of gestation) was estimated on the basis of fetal measures and phenotypic characteristics given by Njaa (2012) in goats. The age of the remaining embryos/ fetuses was estimated by using the formula derived by Singh et al (1979) in goat. The formula was 1/3 W = 0.009 ( t ‐ 30), where W = body 1/3 weight (g) of fetus and t ‐age (days) of fetus.…”
