ABSTRACT
This study evaluated the effects of shearing at 50 days of gestation on the productive, reproductive and response to a gastrointestinal parasite challenge of male offspring from weaning (104 d) to 18 months old. In total, 79 Polwarth male lambs were used, 44 single (S) and 35 twin (T) born to ewes either shorn at 50 days of pregnancy (PS, n =41) or shorn at 62 days post-partum (U, control, n = 38) resulting in four sub-groups: SPS: single male lambs born to ewes shorn at 50 days of pregnancy (n = 23), SU: single male lambs born to postpartumshorn ewes (n = 21), TPS: twin males lambs born to ewes shorn at 50 days of pregnancy (n = 18) or TU: twin female lambs born to postpartum shorn ewes (n = 17). The lambs were kept together on improved pasture throughout the entire experiment. Body weight, body condition score and fecal eggs count were recorded every 14 days from weaning to 18 months old.
Ultrasound measurements in vivo were performed at 12.5 months and 14.6 months old to estimate of ribeye area (REA) and backfat thickness (BFT) in the ongissimus dorsi muscle and the thickness of fat in the hip region (P8).
Furthermore, plasma testosterone concentration was determined once every two weeks to establish the age at onset of puberty. PS male lambs were heavier (P = 0,02) than U male lambs. Shearing treatment had no effect on none of the parameters of body development (P ˃ 0,05). However, REA (P = 0.06) and P8 (P = 0,02) were higher at 14.6 mo than 12.5 mo old. Testosterone concentration, age at puberty and testicular weight were not different (P ˃ 0,05) among treatments. Single male lambs reached puberty earlier (P = 0.06) than twin. Prepartum shearing did not affect the parasite egg count and the Famacha index. The study concludes that ewe shearing at 50 days of gestation positively influences the bodyweight of male offspring from weaning onwards but not the other evaluated traits MenosABSTRACT

Sixty steers were fed during first winter with different levels and source of protein. The steers grazed on improved pastures until reached 350 kg of liveweight,
assigned to a finishing period on pastures-P (n=30) or grain-G (n=30). Treatments were: T1) P13-P: diet with 13% of crude protein (PC) and fattened on P; T2) P13-G: 13% PC, fattened on G; T3) P15-P: 15% PC fattened on P; T4) P15-G: 15% PC fattened on G; T5) P17-P: 17% PC fattened on P; T6) P17-G: 17% PC fattened on G; T7) U100-P: 15% PC, using urea 0.5% of diet, fattened on P, T8) U100-G: 15% PC, urea 0.5% of diet fattened on G; T9) U50-P: 15% PC urea1% of diet, fattened on P, T10) U50-G:15% PC urea1% of diet fattened on G. The aim was to evaluate the effect of the combination of the diets (first winter stocking and finishing periods) on
carcass and meat quality (subcutaneous fat cover-SF, meatcuts/fat ratio- C:F, color of fat-FC and meat-MC, marbling- Marb). There was a clear effect (P<0.05) of the
finishing period in SF, C:F, FC and MC. Grain diets improved FC and MC, presenting higher values of SF and lower C:F ratio than grass fed animals. It was not observed
any clear effect of levels and source of protein in carcass and meat quality. Comparing T1 vs. T2, steers form T1 showed differences (P<0.05) on SF and Marb. Those results suggest that the level of protein could affect the growth of the animals and their tissue composition considering the finishing diet regimes. |
