Abstract
Effect of Parity, Period and Season of Calving on Production and Reproduction Traits on Deoni Cattle
Highlights
Deoni is one of the dual purpose cattle genetic resources among the forty one descriptive breeds of India
Least squares analysis technique (Harvey, 1966) were used for non-orthogonal data to find the effect of parity, period and season of calving on lactation milk yield (LMY), lactation length (LL), service period (SP) and calving interval (CI) of the cattle as per the following formula, and 195.23 ± 2.62 days respectively (Table 1)
Overall mean lactation milk yield and lactation length was estimated as 819.98 ± 16.50 kg Lactation milk yield and lactation length of Deoni cattle were highly influenced (P
Summary
Deoni is one of the dual purpose cattle genetic resources among the forty one descriptive breeds of India. Deoni Improvement Centre (DIC) was established in the year 2002 for genetic improvement of the breed at Southern Regional Station, ICAR-NDRI, Bangalore. The Deoni cattle are being maintained under semi-intensive management system since introduction in the farm from its home tract (Das et al, 2011). Deoni, is a medium to heavy sized cattle which is found in three colour variations i.e., balankya (clear white colour body), wannera (clear white with black colour at both the sides of the face) and shevera (white body with irregular black spots). Cows of Deoni breed have a milk yield of 868.24 ± 49.56kg per lactation. Deoni bullocks are very good for drought purpose
