“…The NEFA levels (ranged from 0.42 to 0.46 mmol L-1) in T2 and T3 ewes during peri-lambing period take place in normal levels (NEFA, < 0.45 mmol L-1) described by Mohammadi et al (2016). Serum glucose level in the present study was in accordance with previous experimental studies that recorded serum glucose levels to be higher in lactation than pregnancy in ewes (Silva et al, 2015).The previous authors defined that the increase of glucose may reflect the recovery of feed intake and improving energy status of the ewe after lambing. Negative energy balance appears to be related to the glucose demands of the fetal-placental unit in pregnant ewes (Mohammadi et al, 2016).…”

“…In T2 and T3 ration ewes moved and cleaned their lambs more frequently and depending on their maternal experience this can enhance lamb activity. Similarly, Silva et al (2015) noticed that lamb strength is influenced by nutritional reserves at birth (amount of brown adipose tissue) and locomotor ability. Brown adipose tissue supplies lambs with energy for thermoregulation and nutrition from birth until colostrum (Silva et al, 2016).…”

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.

“…However, lactating ewes were lower condition score and body weight due to higher nutritional requirements in this phase (milk production) (Scarpino et al 2014, Silva et al 2015. The animal categories with lower body weight (weaning lambs and weaned lambs) had a higher fecal egg count (Table 3) and this positive correlation may be explained due to these sheep category have incomplete developed of the immune system.…”

Infections with gastrointestinal nematodes can impair both the animal health and performance. Thereby, the aim of this study was to evaluate the use of targeted selective treatments as the FAMACHA © system and faecal egg count on controlling gastrointestinal nematodes in different sheep categories under grazing system. Thirty Santa Inês sheep, six in each category (six weaning, six weaned lambs, six non-pregnant ewes, six pregnant ewes and six lactating ewes were used. Sheep were weighed, and blood and faecal samples were collected on day 0, 15, 30, 45, 60 and 75 for determination of faecal egg count (FEC), packed cell volume (PCV), total plasma protein (PPT) and the mucosa colour by FAMACHA © system in the morning (1) and afternoon (2). The faecal egg count was higher (p=0.0039) in weaning and weaned lambs compared to the non-pregnant, pregnant and lactating ewes. Also, FEC differed between ewes with higher counts in lactating ewes. The observation of eye mucosae showed a frequency of 100% of FAMACHA © scores ranged of 2.45 to 2.91 in the morning, differing (p=0.0494) among the categories, where weaned lambs showed better score. The animal categories and period interaction had a significant (p=0.0148) effect on FAMACHA © score 1 with better score in weaned lambs compared to the pregnant ewes at day 0, 15 and 75. In addition, weaned lambs were presented better FAMACHA © score compared with weaning lambs and lactating ewes at day 45 than weaning lambs at day 60 and 75. Packed cell volume in the morning and in the afternoon was influenced by days of collection with lower percentage at 30 days of experiment. The FAMACHA © system seems to be a suitable method to detect parasite infections. However, use of all available methods increases the accuracy of the diagnosis and promotes better control of gastrointestinal nematodes in grazing sheep.

“…In response to the high ambient temperatures, ewes tend to increase physiological traits and modified your behavioral responses, with decrease dry matter intake (Marai et al, 2007;Silva et al, 2015b). Physiological and behavioral changes promote alterations not only in the level of blood metabolites (Silva, Marques, Torreão, Araújo, & Bezerra, 2015a;Silva et al, 2015c) but also in metabolic hormones (Marai, El-Darawany, Fadiel, & Abdel-Hafez, 2008;Sejean, Maurya, & Naqvi, 2010;Macías-Cruz et al, 2013). Given the climate change and gradual global warming scenarios, researches that evaluate the adaptive capability of ewes under unfavorable conditions are required, mainly in the arid and semiarid environments.…”

ABSTRACT. This study was realized to evaluate the effect of concentrate supplementation and time scales of evaluation on behavioral and physiological responses of pregnant ewes on grazing system. The experimental design was a randomized 2 x 2 x 3 factorial arrangement (two breeds: Morada and Santa Inês; two concentrate supplementation levels: 0.5 and 1.5% of body weight; and three time scales of evaluation: 10, 20 and 30 minutes) with six replicates per treatment. The physiological parameters were influenced by period of the day and breeds, with higher values in the afternoon to Santa Inês ewes. Also, influence of concentrate supplementation was found between the breeds with greater values in Santa Inês ewes. But, it did not alter the physiological parameters among animals of the same genetic group. The grazing activity was influenced (p < 0.05) by the scales of observation intervals. Interval of 10 minutes was the most effective methodology to assess accurately the behavior of these animals due to higher number of the registries, offering higher data reliability. Morada Nova breed exhibited less time grazing (p < 0.05) on the 10-minute scale compared to 20 and 30 minutes, which were similar (p > 0.05) for such a feature. Thus, the pregnant ewes exhibited high adaptive capability with observations of 10 minutes for better description of grazing activity in Morada Nova.
