“…d -1 ) by Blackbelly ewes reared in tropical conditions on pasture without adding any supplement [9], the supplement proves to be of undeniable interest since it produced a 46% gain of milk. The small amount of additional milk obtained for H-fed ewes has also been observed by Aboul-Naga et al [1], who measured only a 9% milk supplement for a diet providing 125% of production requirements.…”

-Experiments were carried out to determine the effects of supplementation upon milk production and growing performances of Martinik hair sheep. Ewes weighing 49 kg LW were used in a 2-season experimental study. In the first trial, 3 energy supplement levels were offered to ewes suckling single lambs. The adjusted level (A, 8 ewes) was supplied to ensure that the litter had a daily weight gain (DWG) of 250 g. High (H, 8 ewes) and low (L, 8 ewes) levels were 150% and 75% of level A, respectively. In the second trial, comparative use of the H level was studied with 3 animal requirement levels: ewes suckling single lambs (SI, same ewes as H ewes), twins (TW, 8 ewes) and triplets (TR, 6 ewes), respectively. The experimental design was replicated in a second lambing season. The basal diet was chopped Digitaria decumbens hay (0.6 UFL, 4.6% CP) offered ad libitum. Supplements were composed of maize (65%), soya bean (3%), fish meal (8%) and dehydrated alfalfa (24%). The milk production (MP) of ewes on the L diet was lower (P < 0.05) than that of ewes on the A and H diets: 1142, 1415 and 1518 g . d -1 , respectively. H-fed ewes fattened during the lactating period while A and L ewes respectively maintained and lowered their body condition score (BCS). Differences recorded for lamb DWG were low, but this trait reached a maximum of 248 g . d -1 . MP varied significantly (P < 0.05) according to the litter size. Individual DWG was different for single, twin and triplet lambs (P < 0.001): 261, 188 and 143 g . d -1 , respectively. In intensive breeding conditions, recommended daily energy allowances taking into account a good BCS of ewes for successive reproduction are 1.47 UFL for single-suckling ewes and 2.17 UFL for twin-suckling ewes, in order to obtain a DWG of the litter of 250 and 400 g . d -1 , respectively.Martinik ewes / supplementation / milk production / pre-weaning growth Résumé -Alimentation des brebis allaitantes Martinik élevées dans des conditions intensives : effets de différents niveaux de concentrés ou de la taille de portée.

“…Milk yield of ewes rearing single or twins lambs increased with advancing of lactation period till it reached a peak at the second week then, it decreased gradually till the end of lactation period. Similar, results were reported by Aboul-Naga et al (1981) who found that differences due to number of suckling lambs were highly significant in Rahmani ewes. Also, Hassan (1995) indicated that ewes rearing twins produced ore milk (74.8 kg) than those suckling single lambs (71.2 kg), during 138 days and 136 days, respectively.…”

“…Ewes lambed during spring season (February) were fed green fodder during late pregnancy period and the whole lactation period.

Breed differences were significant (P 0.01) in TMY and LL. Ewes rearing twin lambs produced significantly (P< 0.01) more milk than those rearing single lambs. Ewes lambing in the spring had greater milk yield compared to ewes lambing in summer and autumn. Ewes  4-5 years of age showed relatively higher milk yield than younger or older ones. Fat% of 36 ewes (18 Farafra and 18 Chios) averaged 6.17 for Chios which was significantly (P 0.01) higher than 5.59% for Farafra. Also, Chios had slightly higher TS% than Farafra (16.04% vs. 15.59%), respectively. Protein content for Chios and Farafra milk differed significantly (P 0.01) and averaged 5.62% and 5.31%, respectively. Chios ewes had higher milk energy (4.59 MJ/kg) than Farafra (4.34 MJ/kg). The autumn lambing ewes had a significantly higher fat%, TS% and milk energy (MJ/kg) than either summer or spring lambing season.

“…In Egypt, sheep population are the third in terms of their contribution to the provision of red meat after cows and buffaloes, which are considered the strategic stockpile of food security that play an important role as a source of meat. In addition, sheep as a source of meat, milk, and wool can contribute significantly in solving the problem of animal protein deficiency, which is considered the most important food security problem for the country (Aboul-Naga et al, 1981). Around five million sheep have been living in Upper and Central Egypt as well as the governorates beyond the valley (Marsa Matruh, North and South Sinai, Red Sea, Nubaria, and New Valley) (El-Malky et al, 2019).…”

This study aimed to evaluate the effect of the inclusion of Sesbania sesban hay (SH) at rates of 10, 20, and 30% in the rations on the expense of berseem hay (BH) on milk yield and composition, reproductive performance of Ossimi ewes, and the growth performance of their offspring. Thirty-six Ossimi ewes with the initial average body weight of 38.31 ± 0.91 kg were chosen prior to 30 d of lambing and used in a randomized complete block design with four experimental rations. Rations were formulated as follow: R1 (60% concentrate feed mixture (CFM) and 40% BH) and served as control, while the tested rations R2 (60% CFM + 30% BH + 10% SH), R3 (60% CFM + 20% BH + 20% SH) and R4 (60% CFM + 10% BH + 30% SH). The feeding trial was started at the last month of gestation, through the delivery, and lasted along the lactation period.Results demonstrated that feed conversion was somewhat lower with the inclusion of rations by SH. The inclusion of the SH in all tested rations significantly increased blood serum urea-N concentrations. In addition, serum total protein, albumin, cholesterol, ALT, and glucose concentrations were significantly increased (P<0.05) with R4 compared with those of control one. The inclusion of SH at 20% (R3) and 30% (R4) resulted in a decrease (P<0.05) in milk yield. Substitution of BH by SH at 30% (R4) led to a reduction (P<0.05) in milk fat compared to the rest of the other groups. In contrast, milk protein values followed the opposite trend for milk fat values. Otherwise, concentrations of lactose, total solids, and SNF didn't significantly change by dietary treatments. The interval from lambing to first estrus (d) for ewes fed on SH was longer than ewes fed on control. Comparably, estrus duration (hour) showed an increasing trend as increasing SH level in the rations. While SH supplementation in ewe's rations decreased both P4 and E2 concentrations (P<0.05) compared to those of control one. The economic efficiency was noticeably higher with the inclusion of SH in ewes' rations. Accordingly, it could be concluded that substitutions up to 30% of BH by SH for ewes' rations have not left any adverse effects on productive and reproductive performance, as well as the favorable metabolic parameters reflected in the high economic efficiency of the experimental rations that provisionary depending on the cost and the availability of berseem hay.
