2022, Small Ruminant ResearchCitation Excerpt :Direct heterosis amounted to 38.4% (P < 0.01; Table 4), but the other contrasts were not significant (P > 0.05). The derived heterosis estimate was higher than corresponding estimates of 4.1–13.8% (Long et al., 1989; Bittante et al., 1996; Mavrogenis, 1996; Boujenane and Kansari, 2002) but consistent with other estimates of around 39% (Fogarty et al., 1984; Pitchford, 1993) in the literature. It is notable that the present study involved a specialist meat breed and a dual-purpose breed.
Quality traits and modeling of coagulation, curd firming, and syneresis of sheep milk of Alpine breeds fed diets supplemented with rumen-protected conjugated fatty acid
2014, Journal of Dairy ScienceCitation Excerpt :These breeds are traditionally reared for meat production (mainly from weaned lambs and castrated yearlings). The Lamon breed has been studied in the past decades (Bittante et al., 1996; Ramanzin et al., 1991), but no previous study has examined the quality and coagulation properties of milk from the Veneto sheep breeds. The contents of fat, protein, and lactose in the Veneto sheep breeds are close to the average values reported by Barłowska et al. (2011) for ovine milk in their literature review on the composition of ruminant milk, and are very good if compared with milk traits recorded for specialized dairy ewes, such as the Sarda sheep (Mura et al., 2012; Vacca et al., 2013).
Genetic (co)variance components for ratio of lamb weight to ewe metabolic weight as an indicator of ewe efficiency
2012, Livestock ScienceCitation Excerpt :Estimates for crossbreeding parameters are scarce in literature for sheep. Bittante et al. (1996) also observed important effect of heterosis in LWW in crossbreeding between Finnsheep and an Alpine sheep breed. In this study, the effect of direct heterosis observed for the traits LWW and EW was not verified in WEE.
