“…Furthermore, the better growth in the current study may be attributed to polyphenols and other phytochemicals in PPCP which could transfer to the milk of ewes and consequently to their offspring. In agreement, the dietary polyphenols during the lactation lead to an enhancement in the metabolic reprogramming of the offspring [ 15 , 16 ]. Moreover, the better growth in the current study may be attributed to the enhancement of serum antioxidant status and the T 3 hormone of lambs suckling from ewes fed diets supplemented with PPCP ( Figure 2 and Figure 3 ).…”

“…Noteworthily, nutrition during lactation is critical for milk production [48], whereas milk production is an energy demand process which causes stress in the animal, especially during the early stage of lactation due to the associated extreme physiological and metabolic changes [8,49]. Accordingly, introducing complete balanced diets alone as an animal requirement in this stage of production is not good enough, but also using supplemented diets with natural antioxidant is an important measure of animal husbandry, especially under controlled farming systems, to assimilate natural pasture-living animals [4,15]. PPCP is a waste material of the PPC processing industries and represents about 36-48% of the whole fruit [19].…”

“…Moreover, high lamb mortality is witnessed in the first month of life [12], which is associated with the incidence of oxidative stress, resulting in decreased growth, increased disease susceptibility, and economic losses [13]. Consequently, proper maternal nutrition and antioxidant delivery during the early lactation period could not only improve the ewes' health status, milk production and reduce oxidative stress, but also improve lambs' growth and health [14][15][16].…”

Prickly pear cactus peels (Opuntia ficus-indica, PPCP) are sustainable byproducts available in arid regions and a rich source of antioxidants. Fifteen multiparous Barki ewes (2–3 years old, 46.94 ± 0.59 kg body weight, BW) at postpartum were individually distributed in three equal groups and fed diets supplemented with PPCP at doses of 0, 5 and 10 g/head/day. Lambs were individually distributed into three equal groups according to their mothers’ groups to investigate the maternal effect on lambs’ growth performance, hematology and serum metabolites. This trial lasted for 56 days from birth to weaning. Moreover, nine adult male Barki sheep with a live BW of 65.76 ± 0.54 kg were randomly allocated into three equal groups to determine the effect of PPCP on the nutrient digestibility of the experimental diets. The results indicate that supplementing PPCP at low levels (5 g/head/day) increased milk yield (p = 0.050), fat-corrected milk (p = 0.022), energy-corrected milk (p = 0.015) and the yield of milk constituents compared to 10 g PPCP and the control group. In addition, lambs suckling from ewes fed the diet supplemented with 5 g PPCP had a higher (p = 0.001) weaning BW compared to other groups. Serum total protein, globulin, superoxide dismutase, glutathione peroxidase enzyme activities and the triiodothyronine hormone improved significantly in lambs suckling from ewes fed diets supplemented with 5 g PPCP compared to the control group. Serum cholesterol profile and kidney activities were enhanced significantly in lambs suckling from ewes fed diets supplemented with 5 and 10 g of PPCP compared to the control group. The dietary supplementation of 5 g PPCP improved the crude protein digestibility, digestible crude protein value, nitrogen balance and rumen fermentation characteristics of male sheep compared to the control group. In conclusion, supplementation with 5 g PPCP improved ewes’ milk production, offspring growth and physiological status. Furthermore, it improved the crude protein digestibility and rumen fermentation characteristics of Barki sheep.

“…Further, we corrected for age of ewe, weight of ewe, and sex of lamb. All these effects significantly influenced lambs' average daily gain, as expected (13,14) and are therefore not considered in the following discussion. The proportion of vegetation types of high nutritional value differed between the islands.…”

Lamb Performance on Island Pastures in Northern Norway

et al. 2020

The Norwegian sheep industry is based on utilization of "free" rangeland pasture resources. Use of mountain pastures is dominating, with about two million sheep grazing these pastures during summer. Regional challenges related to e.g., loss of sheep to large carnivores make farmers think differently. The Norwegian coastline is among the longest globally and is scattered with islets and islands. Alone along the coast of Nordland county, it is estimated more than 14,000 islands. Use of islands for summer pasture is an alternative but there is a limited knowledge about such a management system. In this study, we examined lambs' average daily gain on island pastures at the coast of Norway. In total 230 lambs on three islands (Sandvaer, Sjonøya, and Buøya), with varying pasture quality and stocking rate, for 3 years (2012, 2013, and 2014). At Sandvaer as much as 92% of the island was characterized as high nutritional value while at Sjonøya and Buøya only 15%, was characterized high nutritional value. We found an average daily lamb growth rate of 0.320 kg d −1. Lambs on Sandvaer had a higher daily gain (P < 0.05) than those on Sjonøya and Buøya, and lambs' average daily gain was significantly lower (P < 0.05) in 2013 compared to 2012 and 2014. We conclude that with a dynamic and adaptive management strategy there is a potential to utilize islands for sheep grazing during summer.
