The influence of lamb rearing system on ewe milk and lamb growth traits in dairy sheep

Effect of selected factors (body weight, age, parity, litter size and temperament) on the entrance order into the milking parlour of Lacaune ewes, and its relationship with milk production

“…Milk production records of the population studied were highly above the official Hungarian data (lactation milk yield: 153.6 kg, length of lactation: 126 days) (HSGBA, 2018). Parameters of milk fat and protein were in concordance with earlier reports (Park et al, 2006;Makovický et al, 2014;Chay-Canul et al, 2020;Margetín et al, 2020).…”

“…The daily milk yield and the length of lactation of the studied animals were more advantageous in comparison to earlier reports (Oravcová et al, 2018;Makovický et al, 2019;Margetín et al, 2020). Milk production records of the population studied were highly above the official Hungarian data (lactation milk yield: 153.6 kg, length of lactation: 126 days) (HSGBA, 2018).…”

Effects of milking system in suckling period on growth, reproduction traits, and milk yield of East Friesian-cross dairy sheep

“…For the same groups, the ADG were 314.4, 348.0, and 358.2 g respectively, for the 0-120th days (McKusick et al, 2001). Margetín et al (2020) reported that ADG was similar in groups from birth to weaning periods. In the present study, it can be said that the live weight and growth values determined in Tahirova sheep lambs are similar to the values determined in East Friesians and their crosses, especially until the age of 2-3 months, then they are slightly lower for the following periods.…”

“…Yet, milking practice in the suckling period of dairy sheep raised in Turkey is limited (Altın and Çelikyürek, 1996;Dikmen et al, 2007). It has been determined that suckling or partly milking programs significantly affect the growth of lambs and the milk yield characteristics of ewes (Knight et al, 1993;McKusick et al, 2001;Margetín et al, 2020). While there are several studies on the effects of the practices in suckling period on the next reproductive performance of ewes (deNicolo et al, 2006;Godfrey and Weis, 2016;Murphy et al, 2017), studies on the breeding performance of the female lambs are scarce (Gaskins et al, 2005).…”

“…The live weight values of Tahirova sheep lambs, which were subjected to different milking programs during the suckling period, were similar in the groups. In a study on dairy sheep in Slovakia, it was determined that the live weight of lambs was similar among the groups in artificially raised, once-daily milked, and not-milked groups (Margetín et al, 2020). In East Friesian sheep, it was found that the live weight and ADG on the 30th day were similar among the groups, which artificially reared lambs; after the morning milking of the suckled lambs and continuously suckled lambs, the live weight mean on the 120th day was determined as 43.7, 45.9, and 47.3 kg in the groups, respectively (McKusick et al, 2001).…”
