“…Several reports indicate that the EF breed has a low ability to adapt to exotic climatic conditions, resulting in lower milk yields mainly under dry or hot conditions (Gootwine and Goot 1996;Angeles-Hernandez et al 2014). Hunter et al (2015) report that the variability of response of the East Frisian breed and its crosses is maybe due to insufficient nutrition to maximise milk yield under grazing condition, as in the current study, or inadequate milking pressure; although the heat, humidity and health problems are environmental factors that have been strongly associated with the low and moderate milk performance of the EF genotype outside the native conditions (Gootwine and Goot 1996).…”

“…The sheep's BW decreased by 4.01 kg from fourth month of pregnancy to lambing; the sheep was weighed one day after lambing; hence, the loss of BW can be due to the expulsion of lamb or lambs, amniotic fluid and placental mass (Sahlu et al 1995) and the decline of feed intake during the days previous to lambing (Charismiadou et al 2000). The increase of the ewes' BW during lactation was similar to the weight gain observed by Godfrey et al (1997) and Hunter et al (2015). After the ewes lost weight in early lactation, they began to gain weight again during the first month of lactation approximately; in contrast, milk production declined over time.…”

The study was conducted to analyse the effect of sheep body weight (BW) at mating, mid-pregnancy, lambing, early lactation, mid-lactation and late lactation on milk yield and patterns of milk production. Also, the effects of environmental factors such as number of lambing (NL) and type of lambing (TL) on BW and milk production were analysed. A total of 52 multiparous East Friesian ewes from an experimental flock were used. Ewes were assigned to three different groups according to their BW at each productive stage: low (LBW), moderate (MBW) and high BW (HBW). Lactations were fitted using the mechanistic model described by Pollott. Total milk yield (TMY), peak yield (PY) and time at peak yield (TPY) were also calculated. HBW ewes had consistently higher TMY (p < .001) and PY (p < .05) values, than LBW and MBW in most of productive stage measured. There was a positive linear relationship (p < .05) between TMY and BW in all-productive stage, except at mid-gestation where the relationship was quadratic. HBW ewes weighted at midpregnancy showed the highest values of maximum secretion parameter (p ¼ .04) of Pollott model, which could partially explain the better milk yield of HBW ewes. A significant effect of NL on BW (p ¼ .007) and TMY (p ¼ .007) was observed. The BW ewe's in pregnancy and early lactation is a useful indicator at farm level to improve the milk yield performance in dairy sheep.

“…Calasso et al (2015) used ewe’s milk for the manufacture of cheeses with 4.3 per cent protein and 5.6 per cent fat. Hunter et al (2016) reported ewe’s milk protein varying from 4.81 to 5.34 per cent, fat varying from 3.73 to 6.18 per cent and lactose varying from 5.17 to 5.87 per cent.…”

Purpose Thistle flower (Cynara cardunculus) aqueous extracts, as rich source of milk-clotting peptidases, have been widely used for cheeses marketed under the Registry of the Protected Designation of Origin, as it is the case of Serra da Estrela cheese, manufactured from raw ewes’ milk and without addition of any commercial starter culture. This paper aims at studying the influence of six different ecotypes of thistle flowers in cheese properties during the ripening and of final products. Design/methodology/approach Cheeses were produced with different thistle flower extracts and then the clotting time, weight and colour of cheeses, as well as texture properties and sensorial characteristics, were evaluated. Findings The clotting time varied from 47 to 66 min, and the weight loss along ripening varied between 32 and 40 per cent. There was some influence of thistle flower ecotype on the colour during ripening and in the final product. The results of texture analysis revealed significant differences between the thistle ecotypes: crust firmness varying from 2.4 to 5.6 N; inner firmness from 0.82 to 1.82 N; stickiness from −0.5 to −1.60 N; adhesiveness from −3.0 to −11.3 N.s; and Ecotype C was particularly distinguishable. Sensorial evaluation revealed differences among the cheeses, with Ecotype C receiving the highest score for global appreciation. Originality/value The usage of different extracts of thistle flower to produce Serra da Estrela cheese with different properties is a novelty, and it allows the possibility of manipulating this parameter in the future so as to produce cheeses with specific characteristics, addressed to different consumer targets.

“…Also, the same authors defined that BCS at 2.0, 2.5 and 3.0 in 18 days of lactation has assured BW 73.4, 76.1 and 79.5 kg however, at 79 days of lactation, it was 77.7, 79.2, 82.2 kg, respectively. The effect of BW measured in pregnancy and lactation has been demonstrated in some previous studies which supplemented protein and energy (Hunter et al, 2015). Also, Ángeles Hernández et al (2018) showed the most relationship between feeding and BW at mid-lactation when ewes had a greater energy intake, which determine greater availability of milk synthesis reaching the mammary gland and higher udder volume.…”

“…They also defined that twins or triplets lambs imposes more demand on the mammary gland to meet the needs of the offspring and milk production for their growth. Indeed, the effect of nutrition on mammary gland development and suckling milk production appears to be independent of the milk amount (Hunter et al, 2015), the degradability (Antunovic et al, 2017) and dietary protein or energy concentration (Ángeles Hernández et al, 2018). In the current results, feeding ewes on ration contents protein or energy has more appositive results on number and growth of lambing from birth to weaning than control ration.…”

The purpose was to determine impact of nutritional treatments containing energy and protein on ewes body condition score (BCS), body weight (BW), milk production, newborn of lambs behavior and blood parameters of twin-bearing ewes. At trimester of pregnancy, one hundred-fifty shearing Rahmani ewes had been scanned to choose twin-bearing ewes. Then, twenty-four ewes had been diagnosed twinbearing actually. They age from 3 to 4 years, BW 51.30±0.39 kg and BCS 2.54±0.16 (on a scale of 1 to 5). They were allocated to 3 rd nutritional treatments (n=8/ treatment). Ewes in T1 were received rations consisted of concentrate fed mixture (CFM) + roughage included berseem hay (BH) + rice straw (RS). However ewes in T2 and T3 were fed the previous ration addition with protected fat (PF) and corn steep liquor (CSL), respictevely. Then, T1, T2 and T3 were offered from 100 day until weaning according to NRC (2007). Resulting indicated that either T2 or T3 to twin-bearing ewe from trimester of pregnancy to weaning could be achieved the greatest (P<0.05) BW and BCS, improvement (P<0.05) of lambs behavior, more amount of suckling milk , composition, had more (P<0.05) lambs' body weight and verity serum blood metabolic than those ewes in T1 ration. Then, this study concluded that it is optimal for farmers to addition either energy (as 4% PF) or protein (as 20% CSL) to rations which have benefit for twin-bearing ewe without any losses in twin-bearing and performance growth of their newborns.
