The aim of this study was to evaluate the effect of pre slaughter lairage time on carcass and meat quality of cattle. Thirty Hereford steers were randomly assigned to two treatments according to lairage time in the slaughterhouse: 12 hours (Treatment 1, n = 15) and 3 hours (Treatment 2, n = 15). The pH measurements were taken at 1, 3, 6, 12, 24, 36 and 48 hours post mortem at Longissimus thoracis et lumborum (LM) muscles. Muscle color was measured on the LM at L*, a* and b* color space, after 2 days of aging and one hour of blooming. Shear force measurement was obtained also on the LM and after 2 aging days using Warner Bratzler. Data was analyzed by the SAS software applying GLM and GLIMMIX procedures. Carcass pH did not differ between treatments in any evaluated time (P>0.05). The pH showed an appropriate decline curve, with values within the acceptable standard, between 5.5 and 5.8. The L *, a *, b * and shear force parameters did not differ between treatments (P>0.05). In summary, no differences in carcass and meat quality were found between the evaluated lairage durations. |

Abstract:
The effect of level of CP fed during late gestation on reproductive performance and milk production was studied in multiparous cows. Sixty-eight pregnant Angus cows were used. At 121 d prepartum, cows were blocked by BW (409 ± 57 kg) and expected calving date, randomly assigned to a low-protein (LP = 6% CP) or high-protein diet (HP = 12% CP), and allocated to 12 pens per treatment.
After parturition, all cows were managed in a single group until weaning. Body weight and BCS were determined at the start of the experiment, at calving, and at weaning.
Nonesterified fatty acids, insulin, IGF-1, and glucose were determined every 24 d prepartum and nonesterified fatty acids and glucose every 38 d postpartum. Progesterone was quantified weekly to indicate luteal activity and estimate interval to first estrus. Milk production was measured until weaning. The HP cows had greater BW gain during the prepartum period (P < 0.01) and tended to gain more BCS (P = 0.06) than LP cows. The prepartum diet did not affect gestation length (P = 0.44) or interval from calving to the onset of luteal activity (P = 0.35).
Pregnancy rates, milk quality, and production were not influenced by dietary treatments. Cows in the HP treatment had greater prepartum serum urea concentrations than LP treatment (P < 0.05). In conclusion, protein level prepartum in multiparous beef cows affected the BW change at calving, without consequences on reproductive performance and milk quality and yield. |
