Efecto del peso y la puntuación de la condición corporal de vacas gestantes en las características de la canal de su progenie: Meta análisis
The objective of the meta-analysis was to evaluate the effects of beef cows weight variation during the 2nd and / or 3rd trimester pregnancy on some parameters of the progeny carcass. The cow weight gain during this gestational period was calculated to standardize the treatments: moderate loss (ML= cows that lost 0 to 5 % of weight) and moderate gain (MG= cows that gained 0 to 5 % of weight). The effect size for all parameters was calculated as medium difference (MD) with a 95% confidence interval and heterogeneity determined using the Q test and the I2 statistic. A random effects meta-analysis was performed for each indicator separately as the medium control and experimental groups. The cow’s weight variation during the studied time variation did not influence the progeny carcass characteristics (P>0.05). Although, a trend towards greater hot carcass weight (P=0.15) and thickness of subcutaneous fat (P=0.10) was observed in calves from MG cows in relation to calves from ML cows. However, the meta-analysis demonstrated that small variations in cow weight during the final half of pregnancy do not affect progeny carcass characteristics.
期刊介绍:
The MEXICAN MAGAZINE OF SCIENCES PECUARIAS is an organ of scientific and technical diffusion of the livestock sector. Its periodicity is quarterly and arbitrated by pairs in the double-blind mode. Its objective is to make known the results of the research carried out by any scientific institution, in Mexico and in any part of the world, related to the livestock sciences, particularly those that refer to the different disciplines of Veterinary Medicine and Animal Science. The Journal is bilingual, publishes the complete articles in Spanish or English and is included in various indexing services and international dissemination platforms, such as the Index of Mexican Journals of Scientific and Technological Research of the National Council of Science and Technology (CONACYT); In the EBSCO Host database; In the Network of Scientific Journals of Latin America and the Caribbean, Spain and Portugal (RedALyC); In the Ibero-American Network of Scientific Journals of Free Access Veterinary Medicine. Indexed in the ISI Journal Citation Report Science Edition; And Elsevier''s SCOPUS and EMBASE indices.
