Comparison of beef production from young cattle in normalized microclimate
Found that studies microclimate in premises where bulls and heifers are kept in the stall period in different times is different. Yes, the worst level at six o'clock in the microclimate (relative humidity, the concentration of carbon dioxide and ammonia), and the best - at 15 one hour. In the experimental bulls and heifers, depending on the age groups in the implementation of live weight was bulls - 391 kg (15 mo.), Heifers - 328.9 kg (15 mo.). Continued feeding for 18 months led to increased live weight: the calves to 467 kg and heifers - to 391.7 kg. Established that the implementation of the live weight of bulls and heifers, depending on different age groups bullocks 391.0 kg (15 months of age) and heifers 328.9 kg (15 months of age) and 467, 0 kg - bulls (at 18 months of age) and 391.7 kg - heifers (at 18 months of age). Based on the data show that more effectively grow and fatten bulls as 15 months of age and under 18 months of age than heifers. Therefore, it is advisable to set other conditions for feeding and heifers to be more intensively to increase live weight.
