Holstein Bulls

Abstract. The objective of this study was to investigate the phenotypical differences in feed conversion, carcass composition, and meat quality of two cattle breeds representing either the accretion type (Charolais) or the secretion type (Holstein). Eighteen Charolais bulls and 18 German Holstein bulls were raised and fattened under identical conditions on a high energy level with concentrates and hay. The animals were slaughtered at the age of 18 months. Charolais bulls had a body weight (BW) of 750.6 kg and an average daily gain (ADG) of 1377 g. German Holstein bulls were 84.7 kg lighter with an ADG of 1197 g. The energy expense per kg BW gain was 14% lower in the Charolais bulls compared with German Holstein. Charolais bulls gained more energy in protein than the Holstein bulls and needed less energy per kg protein gain in the hot carcass weight (HCW). The Charolais bulls showed a greater carcass weight and a higher yield grade as well as a greater cross sectional area of the M. longissimus dorsi (LD). Holstein bulls showed a greater marbling score, darker color, and more water binding capacity of the LD. The Holstein bulls gained more subcutaneous, intramuscular, and visceral fat during growth, which reflects the ability of the Holstein as a dairy breed to deposit fat as an energy source for milk production and points out the capability of Charolais for extended protein accretion. The genetic background of the recorded different nutrient utilization and turnover will be investigated in further experiments.

Abstract A total of 168 one-day old broilers (average BW 46.4 ± 0.6 g) were selected to determine effects of natural capsaicin extract (NCE) as a substitute for chlortetracycline (CTC) on performance, antioxidant capacity, immune function and meat quality of broilers [Founded by NSFC (31772612)]. Broilers were randomly allotted into 3 dietary treatments (n = 7) including a corn-soybean meal basal diet (CON), a basal diet + 75 mg/kg CTC (CTC), and a basal diet + 80 mg/kg NCE (NCE). The experiment contained phase 1 (day 1 to 21) and 2 (day 22 to 42). Compared with CON, broilers from NCE showed higher average daily gain at all stages (P < 0.05). On day 42, organic matter, crude protein and gross energy digestibilities of broilers from NCE were higher than those from the other two groups (P < 0.05). Higher percentage of bursa of Fabricius was observed in broilers fed NCE diets compared with CON (P < 0.05). Trypsin and lipase activities in the pancreas of broilers from NCE were higher than those from CON (P < 0.05). Breast muscle of broilers fed NCE diets showed lower L* values compared with CON (P < 0.05). Broilers from NCE also showed higher levels of serum total antioxidant capacity, glutathione peroxidase, superoxide dismutase, lower levels of interleukin-1β and tumor necrosis factor-α compared with broilers offered CON diets (P < 0.05). Compared with CON, lower concentrations of serum urea-N, low-density lipoprotein cholesterol and total cholesterol, higher growth hormone level were observed in broilers fed NCE diets (P < 0.05). In conclusion, supplementing 80 mg/kg of NCE to diets could improve growth performance, nutrient digestibility, antioxidant and immune function, and meat quality of broilers. Moreover, broilers fed NCE diets exhibited similar growth performance and health status to those offered chlortetracycline (CTC) diets.
