“…The results of (Table 4) indicated that there were highly significant differences (p≤ 0.01) in the concentration of triglycerides in the blood in favor of the treatment of feeding frequency three times compared to the frequency of feeding twice daily, which amounted to (28.70 and 20.49) mg / dl, respectively. While the frequency of feeding did not have a significant effect on other blood components, and this result was consistent with what was reached by [9], [19] who did not find significant differences in blood characteristics resulting from the effect of repeated feeding. The addition of moringa had a highly significant effect (p≤0.01) on the albumin concentration in the blood, as the treatment to which moringa was added was significantly superior to the treatment without the addition the concentration of the albumins was (3.79 and 3.33) g/ld., respectively.…”

“…Moreover, feeding frequently can enhance the appetite of lambs, which leads to improved growth and weight gain. These results agreed with the findings of [8], [9] who noted that repeated feeding leads to a significant increase in lamb weights and are inconsistent with the results of [10,11] who did not find a significant effect of feeding frequency on lamb weights. The results of the study indicated that there was no significant effect of adding Moringa seeds on the weight of lambs and weight gain, although there were slight arithmetic differences, but they were not significant.…”

The study included 24 Awassi lambs aged of (3-4) months, distributed randomly into four treatments homogeneous by weight, each treatment includes 6 lambs. The first treatment was fed twice a day without supplementation, second treatment was fed twice a day with addition 5 g of Moringa seeds/head/day, third treatment they were fed three times a day without supplementation, and the fourth treatment was fed three times a day with addition 5 gm of Moringa seeds/head/day. The results of the study showed a significant (p≤0.05) superiority in body weight at the second week in favor of the lambs that were fed twice daily, while the lambs that were fed three times had a significant (p≤0.05) superiority in final weight and total weight gain, and the fourth treatment was significantly superior (p≤0.05) in final weight and total weight gain compared to the second and third treatments. Lambs fed twice daily outperformed highly significant (p≤0.01) in the carcass width at the shoulders. Also, the lambs that were fed twice daily without addition were significantly (p≤0.01) superior in this trait to their counterparts that were fed three times. There was a significant (p≤0.05) superiority in the weight of fat-tail for the treatment with Moringa added compared to the treatment without it. Significant differences (p≤0.05) were observed in the dressing percentage in favor of lambs in the third and fourth treatments. The treatment to which Moringa was added was significantly (p≤0.01) superior in albumin concentration in the blood over the treatment without addition, and the albumin concentration was significantly (p≤0.05) higher in the second treatment compared to the rest of the other treatments. A highly significant (p≤0.01) was observed in the concentration of triglycerides in the blood of lambs fed three times daily.

“…Our results agreed with these of Simensen and Kielland (2013) who reported that keeping sheep outdoors or in other available housing facilities during the lambing season in addition to the main building unit was associated with a higher number of lambs born per pregnant ewe and lambs per ewe at the end of the indoor period. These results were agree with Abozed, et al, (2021) The increase of S/C during heat stress may be due to the loss of embryo at early few days of pregnancy due to abnormal size of oocyte (Al-Katanani et al, 2002 andInskeep, 2002), less heat shock protein (Ju, 2005) and less progesterone secretion from abnormal CL (McNeil et al, 2006), however such effects of housing during heat stress may require further studies.…”

A total of 80 Saidi ewes were used approximately 2 years of age and had an average initial body weight (BW) of 40 ± 2.46 kg. Ewes were divided in two experiments 40 mature saidi ewes in each experiment, The first experiment was in mating season September, 2018 and the second experiment was in mate season January, 2019. Ewes in two experiments were randomly assigned to 4 groups raised under four housing model which was Double Roof Close, single roof close, semi open and open housing model. Ewes, mated in September, lambed during January. Ewes, mated in January, lambed during May. Ewes were kept in double roof and open model houses had higher Conception rate than the other houses in winter and summer seasons respectively. Ewes in semi open and open model in season's summer and winter had higher number of service per conception. The analysis of variance showed that housing models had no significant effect on average birth weight and total birth weight/ewe of lambs. However, lambs born in double roof and single roof housing model tended to have a higher average birth weight than born in semi open and open models.

“…All lambs grew better (242g/d) for H ewes than L ewes (196g/d).No differences were recorded due to feeding frequency. Abozed et al (2021) studied the effect of feeding frequency under different housing systems on physiological responses and growth performance under Upper Egypt hot conditions. Animals were divided into four groups; group I fed twice daily and housed in a semi-open pen, group II fed twice daily and housed in double-roofed pens, group III fed three times daily and kept in a semi-open pen and group IV fed three times daily and kept in a double-roofed pen.…”

inety-six Barki ewes in second parities, aging about two years were chosen before the mating season and randomly assigned to six groups in a 2 x 3 factorial design to examine effects of ewes body weight (30kg as light ewes; L and 40kg as heavy ewes; H) and concentrate feeding frequency (once, 1X; twice, 2X and thrice, 3X) on the productive and reproductive performance of ewes and their offspring. The experimental period represents the reproductive and productive cycle of the ewe i.e., mating, gestation and lactation periods. Animals in the experimental groups were housed and fed separately in 6 pens and each treatment was fed in group. Results illustrated that the heaviest ewes digested all nutrients better than the lighter ewes leading to significantly higher feeding values. The increased frequent feeding lead to better digestibility of CF and NFE; no differences were reported for other nutrients. Heavy weight ewes digested all nutrients better with one time feeding than the two or three times. Nutritive value was higher with heavy ewe than lighter ones. Nutritive value as TDN and DCP were not improved by concentrate feeding frequency. Values of rumen liquor pH were decreased with more frequent feeding. Feeding the experimental ration more frequently lead to an increase in VFA production than feeding once. The heavy weight ewes had more VFA than the lighter ones with all frequent feeding. Heavy ewes produced significantly more milk yield than the light once. Fat corrected milk followed the same trend. No differences were reported for milk composition%. Feeding more frequently increased milk yield and fat corrected milk; milk energy / NEL intake and milk protein/ CP intake followed the adverse trend. The light ewes reported better feed conversion than the heavy weight ewes. Feeding frequency did not affect production efficiency as well as feed conversion. During the dry period the heavy weight ewes had less dry matter intake (DMI), digestible crude protein intake (DCPI), metabolizable energy (ME) and net energy for maintenance (NE m ). While, during the early gestation period no differences were found regarding the above mentioned criteria. With increasing feeding frequency in dry period, the average body weight was significantly increased; DCPI, ME and NE m followed the same trend. Also during early gestation period the above mentioned criteria followed the similar trend. DCPI was more during the early gestation than dry-period. During the suckling period, DCPI followed the opposite trend being better with heavy ewes than light ones with all feeding frequency.
