Diagnóstico de índices zootécnicos e produtivos do rebanho leiteiro do departamento de zootecnia/CCA/UFPB

Abstract

The study was carried out in the Milk Cattle Sector of the CCA / UFPB in Areia-PB, located in the Paraiba’s Agreste mesoregion, a micro-region of the Paraiba swamp, with an 1,425 mm average annual rainfall. Dairy control and reproductive control records were used. The herd is composed of European / Zebu crossbred ¾, with an average of 29 animals per year, between 2008 and 2016. The average milk yield of each control was calculated and consequently, the herd lactation months average. With the data collected, a database was set up in Excel® worksheets (Microsoft, 2010), and compared with the F-Test at 5%. The objective of the study was to evaluate the zootechnical and productive Dairy herd index from the Federal University of Paraiba, Animal Science Department, CCA. The years 2008 and 2009 presented lower data than the others. From 2010 the zootechnical and productive index improved with a technician hiring. Where the total lactation production of the herd was significant, with a good average annual production, the lactation duration in most years was within the range recommended for the breed, the average persistence of the herd in most years is below that is recommended. No statistical significant differences were observed in relation to the calving interval and the average milk yield per calving interval. It was possible to verify through the records related to the production and reproduction used in the zootechnical control, that the indexes need to be improved, since there were possible failures in the productive and reproductive management of the herd.
