“…Dry matter intake (DMI) was measured daily and the ADWG was calculated for the interval between the two weight measurements. The feed conversion rate (FCR) was calculated, dividing the total amount of food consumed (based on DMI) between the weighing days to the total weight gain (Mundan et al, 2012). In this study, apart from the general determination of the FP, DMI, FCR, and ADWG, each trait was evaluated based on the fattening periods between five selected target body weights (W1 = 100 kg, W2 = 200 kg, W3 = 300 kg, W4 = 400 kg, W5 = 450 kg) and days to reach (DTR) these targets were compared.…”

The objective of this study was to determine the association of single nucleotide polymorphisms (SNPs) in selected candidate genes with fattening performance traits in a commercial cattle herd. Fifteen SNPs in 12 candidate genes (LEP, FABP4, DGAT1, TG, IGF1, IGF1R, MYF5, LGB, CAPN1, CAST, GHR, and OLR1) were evaluated in 296 purebred Holstein–Friesian bulls using PCR-RFLP (polymerase chain reaction – restriction fragment length polymorphism). Associations between each segregating SNP and genetic merit for fattening performance were quantified using linear mixed models. Traits included in the study were fattening period, final weight, dry matter intake, feed conversion rate, and average daily weight gain. Apart from the general determination of the above-mentioned traits, each trait was evaluated based on the fattening periods between five selected target body weights (W1 = 100 kg, W2 = 200 kg, W3 = 300 kg, W4 = 400 kg, W5 = 450 kg). All markers with the exception of CAPN1 530, IGF1R, TG, and DGAT1 were associated with at least one of the traits. Furthermore, novel associations were observed for LEP × GHR, IGF1 × LEP, FABP4 3691 × FABP4 2834, and FAP4 3533 × LEP interactions. The results of this study confirm some previously reported associations. Moreover, novel associations have been identified, which may be incorporated into breeding programs to improve fattening performance.

“…Breed is one of the most important factors. The live weight gains and feed consumption are not identical for different cattle breeds (Mundan et al, 2012;Guerrero et al, 2013). Holstein is a widely reared breed for milk production in the world and also about 78% of the European breeds in Turkey are Holstein.…”

This study was conducted to determine the potential effects of drinking water enriched with oxygen on fattening performance and dressing percentages of cattle in a commercial beef enterprise. In the study, a total of 20 male 9-10 month-old cattle, including 10 Simmental cattle and 10 Holstein cattle were used. The animals were equally divided into two groups. While the animals in the first group consumed current drinking water at the enterprise, those in the second group consumed drinking water enriched with oxygen. While the live weights of Holstein and Simmental cattle were 571.60 kg and 615.00 kg, respectively at the end of the semi-annual fattening period, the differences between breeds were statistically significant (P<0.05) for all periods, except for the first month. Daily live weight gains of Holstein cattle were detected as 633 g and 1133 g, respectively at the beginning (1 st month) and the end (6 th month) of the fattening period. The same values for Simmental breed were 933 g and 1233 g, respectively. The animals in the group consuming water enriched with oxygen had relatively higher values than the well water group for live weight change and daily live weight gains during the fattening periods. However, these differences were not statistically significant (P>0.05). In addition, the average feed conversion ratios during fattening were 7.18. and 7.26 respectively for the oxygen-enriched drinking water group and the well water group. It was determined that Simmental cattle (56.55%) had higher hot dressing percentage value than Holstein cattle (54.83%) and also those consuming water enriched with oxygen (56.02%) had higher dressing percentage value (55.36%) than those consuming well water. This was the first study on potential effects of drinking water with energized oxygen on fattening performance of cattle. Thereby, it is thought that the present study would provide a data archive for further studies.

Effects of polymorphisms at LEP, CAST, CAPN1, GHR, FABP4 and DGAT1 genes on fattening performance and carcass traits in Simmental bulls

Abstract. The aim of this study was to investigate the effects of single nucleotide polymorphisms (SNPs) at six candidate genes (LEP, CAST, CAPN1, GHR, FABP4 and DGAT1) on fattening performance and carcass traits of Simmental bulls in Turkey. The analysis covered a total of 81 Simmental bulls grown on a private farm that were randomly selected for their fattening period for use in this study. Genotyping was performed using the PCR-RFLP method. The S20T polymorphism at the CAST gene and the G316A polymorphism at the CAPN1 gene were associated with variation in final weight, fattening period, weight gain and average daily gain (P < 0.05). In addition, LEP A80V had a significant effect on hot and chilled carcass weight and dressing percentage (P < 0.05). There was no association between GHR S555G, FABP4 V110M and DGAT1 K232A markers with the traits analysed. These results suggested that focusing on the novel effects of LEP, CAST and CAPN1 gene polymorphisms on meat production traits might be useful for marker-assisted selection in Simmental cattle.
