Crop and animal production constitute a large part of the people's livelihoods in Bayburt province. In addition, the province has become one of the important animal husbandry centers of the region due to the fact that it is a transit point between the Eastern Anatolia region and the Black Sea region. But the number of small farms in Bayburt province is still very large, and the number of farms that are members of grower organizations is quite small. In addition, the migration of the young population from villages leads to an increase in the average age of the population engaged in animal husbandry and a decrease in the number of animals that can be raised depending on the labor force. In this review, the general status of cattle and small ruminants livestock in Bayburt province was given and the level of livestock in Bayburt province was revealed with current data.

Honey bee queen quality is a critical factor of colony performance. Indications of such qualities can manifest themselves through morphological traits such as wet weight and thorax width. Improving such characteristics is driven in part by nutritional provision in queen-cell-builder hives. We investigated the potential to improve queen quality by adding coenzyme Q10 (endogenous antioxidant) and caffeine (central nervous system stimulator) to feeder syrup in queen-cell-builder colonies for 15 and 20 days prior to grafting, two sets of queens were reared. We recorded subsequent wet weight, body length, head width and length, thorax and wing width and length, and spermathecae diameter. The queen-cell acceptance rate was not affected by either treatment or graft period. Coenzyme Q10 increased wet weight, body and wing length in the first graft, and thorax width, wing length and spermathecae diameter in the second graft. The caffeine treatment increased head and thorax length in first graft and thorax width in the second. A mix of the two substances (coenzyme Q10 and caffeine) increased head width in the first graft and spermathecae diameter in the second graft. This study suggests that the application of coenzyme Q10 to cell-builder colonies at least 15 days prior to grafting can increase reared wet weight (the most significant quality indicator) and thorax width of queen bees.

This study evaluated the correlation between scrotal circumference (SC), body weight (BW) and body condition score (BCS) in relation to breeding age in West African Dwarf (WAD) bucks. A total of 320 WAD bucks from birth to 15 months of age from various farms in Ibadan, Nigeria, were studied. They were grouped as A-birth to 3, B-4 to 7, C-8 to 11 and D-12 to 15 months old respectively, comprising of 80 bucks per group. Semen was collected from 10 randomly selected bucks in each group and analysed. Results showed positive correlation between SC and age; SC increased with age; and at about 8 months of age and over, a consistent SC of 17 cm–18 cm was observed. BW also increased with age; BW significantly affected SC. Also, at 8 months of age and over, SC of 17 cm-18 cm was observed from 9 kg BW and above. However, the correlation between SC and BCS was low and not significant. Semen analysis revealed the best semen quality for groups C and D bucks. In conclusion, we suggest that WAD bucks of 8 months and above, with at least SC between 17 cm–18 cm and of over 9 kg BW, could be used to breed does successfully on the farm.
