Milk production was found to be 2.3 kg/ day during the lactation period. The age at first heat and age at first calving were 19 and 36 months respectively. The inter calving period was 14 months.
Chromosome number and morphology: The karyotyping analysis revealed a diploid chromosome number of 60 comprising of 58 autosomes and two sex chromosome. All the 29 pairs of autosomes were acrocentric in appearance. The X chromosome inn both sexes showed a bi-armed submetacentric appearance. The Y chromosome was acrocentric.
Studies on milk composition: Milk components such as fat, solids not fat and total solids were studied from individual milk samples at weekly intervals in the morning and evening milk.
1. Milk fat: The mean milk fat percentage for the morning and evening at first week was 4.05±0.19, 4.65±0.17 and by 20th week of lactation was 5.92±0.08, 6.55±0.07. The evening milk had uniformly higher fat percentage than morning milk. The fat percentage showed an increasing trend with advancing stage of lactation. Increase in fat percentage was more in the initial stages of lactation, by 10th week there was an increase of 1.30 per cent in the morning and 1.30 per cent in the evening.
2. Solids not fat: The average solids not fat percentage was 8.84±0.12 for morning and 8.92±0.14 for evening milk. The mean solids not fat percentage at first week of lactation was 8.60±0.24 and 8.93±0.22. It was 8.83± 0.11 and 8.76±0.15 % in the morning and evening milk by 20th week of lactation. No trend of increase was observed with advance of lactation. Least square analysis of variance showed the non-significant effect of time of milking and stage of lactation on solids not fat percentage.
3. Fat globule size and distribution: The mean size of fat globule was 3.21 (and the range was 2.54 to 4.07). The mean diameter of fat globules was found to be 3.02±0.05 in the morning and 3.40±0.05 in the evening milk. The average fat globule size was found to be decreasing as the lactation advanced. The sizes of the fat globules were found to be higher than that of goats and lower than that of crossbred cow and buffalo milk.
