“…Overall, the low serum levels of mg and ca in the affected ewes indicate a poor feed supplementation of ewes with Ca and Ca+Mg in conjugation with consuming high levels during late gestation and early lactation period. Mineral supplementation had a beneficial effect on energy balance regulation in ewes at lambing (Ataollahi et al, 2018). Furthermore, the low mineral concentrations in blood of ewes suggest a considerable number of animals in Basra region might be at the risk of a subsequent sub-clinical or clinical hypocalcaemia and hypomagnesaemia.…”

“…Eighty-six percent of producers surveyed supplemented minerals around pregnancy and/or lactation with calcium and magnesium being the major supplements provided mainly in the form of loose licks and blocks. Calcium and magnesium supplementation has been shown to improve the energy balance of ewes and improve lamb immune responses [7]. Therefore, most producers are aware of the requirement for minerals and are supplementing ewes.…”

“…Pre-lambing supplementation of ewes with cereal grains, such as maize has increased colostrum production [6], which would be likely to impact lamb survival through increased nutrition for growth, immunity, and heat production. Supplementation of ewes with calcium and magnesium has been found to increase ewe weight gains with calcium, and lamb weight gains with magnesium [7,8]. Calcium and magnesium are involved in milk production and smooth muscle contraction for parturition.…”

High lamb mortality rates reduce profitability and reduce the perceived animal welfare standards of the industry. This study aimed to understand producer knowledge of lamb mortality rates and causes of lamb mortality, and to investigate various practices and perceptions of producers that may contribute to lamb deaths. Postal and online surveys gathered data on Australian sheep producer’s knowledge and practices around lambing and management practices. Based on results, approximately 50% of producers estimated less than 10% mortality of lambs between birth and marking, compared to published data estimates of 20–25% mortality. Pre-lambing vaccination of ewes was not undertaken by 10–20% of producers. Ninety-six percent of producers vaccinated lambs; however, 17% of Merino and 23% of crossbred lamb producers only gave a single vaccination instead of the recommended initial vaccine and booster. The lower estimated mortality impacts producer’s perceived benefits of management strategies being undertaken. Research undertaken needs to be more effectively distributed to producers via extension services to ensure producers understand the causes of mortality. Important messages to convey to producers include the limited impact of predation in most cases and the total costs of lamb mortality on-farm.

“…Kaneko and Kornelius (1970) have reported the blood Ca limit values in lambs as 8.30-11.43 mg dl -1 . It has been stated in the literature that race, sex, and housing conditions did not affect blood serum Ca level, however, the ration was affected by the Ca content (Ouanes et al 2011) and the low blood Ca level after milk sucking period adversely affected the growth and development of lambs (Ataollahia at al. 2018).…”

This study investigated the effect of different levels of common vetch (CV) grain feed on some blood and rumen parameters and rumen protozoa in lambs consuming sainfoin hay (SH). In the study two-month-old weaned, SH consumed, 36.25 ± 2.49 kg average body weight (BW), twenty-four female lambs were used. Ration groups were established as follows; In the first group (C, control), 2% SH and 0.00% CV of the lamb's live weight (LW) were adopted while in the second group, 1.25% SH and 0.75% CV ( CVI) and in the third group, 0.5% SH and 1.50% CV (CVII) were adopted. Blood and rumen fluid samples were taken twice, once at the beginning of the study and once on the 30th day of the study. Although there were statistical differences in some of the parameters investigated in the study, all blood and rumen parameters were within the normal limits specified for lambs in the literature. In this study, it was concluded that feeding the lambs that are consuming SH with CV 1.5% of their live weight did not have a negative effect and the total ration can be formed using both SH and CV.
