“…Likewise, the higher glucose recorded from L2 sheep than from L1 sheep could be due to the higher dietary energy intake. Similar to the present study, Catunda et al [57] found higher glucose concentration in supplemented hair sheep than un supplemented ones.…”

An experiment arranged in 2 × 3 (2 concentrate supplement levels (CSL) and 3 breeds) factorial was carried out to evaluate the effect of CSL, breeds, and their interaction on feed intake, digestibility, feed utilization efficiency, and blood profiles of Ethiopian fat-tail hair sheep. The CSL were 1% and 1.75% body weight, designated as L1 and L2, respectively. The breeds used were yearling intact male Blackhead Ogaden (BHO), Horro and Washera. Sixteen sheep from each breed were divided into two based on initial body weight and randomly allocated to two dietary treatments for digestibility and growth trials of 10 and 90 days, respectively. Grass hay as a basal diet was offered ad libitum to each sheep. Feed intake every day and live body weight at interval of ten days were recorded for the duration of the experiment. Blood samples and linear body measurements were taken a week before the end and on the last day of the experiment from all sheep, respectively. Dry matter and nutrient intakes, except concentrate supplement and CP, were influenced by the interaction. The higher (p < 0.0001) DM digestibility was recorded from sheep supplemented with L2 than L1. Consequently, sheep supplemented with L2 had significantly higher (P < 0.05) feed conversion efficiency (FCE), average daily gain (ADG) (57.3 vs 44.2 kg), total gain (TG) (5.3 vs 3.9 kg) and final body weight (FBW) than those supplemented with L1. Among breeds, Horro sheep recorded higher (P < 0.05) DM intake, digestibility, and FCE than the rest of the breeds. Consequently, this breed has significantly (p < 0.05) higher TG, ADG, and FBW. Some of the blood hematology (PCV, MCV, neutrophils, and monocytes) and sera metabolites (total protein, urea, and cholesterol) How to cite this paper: Ayele, S., Urge, M. 150values were influenced by the interaction in favor of L2. Hemoglobin concentration was higher for Washera than the other breeds (p < 0.05) but similar for the two CSL (P > 0.05). In conclusion, the study indicate the presence of variation in nutrient intake and utilization, performance traits, and blood profiles among breeds and between CSL, most of which were in favor of Horro breed and high level of concentrate.

“…There are several possible reasons for the lower fertility rate in the thin and very fat group's ewes. However, the most likely reason is that the gonadotropin hormone releasing mechanism in thin and very fat ewes could be affected by the body energy reserves of ewes (Catunda et al, 2013;Boudreau et al, 2014), which has been found to lead to a decrease in the number of follicles (Faddy, 2000). Meyer (2002) reported that poor BCSs have adverse effects on uterine efficiency, ovulation rate and embryo yield.…”

“…The present study showed that animal body fat reserves can affect the return rate and fecundity of ewes. The return rate might be affected by fertility failure or early embryonic deaths for reasons relating to physiological, endocrine and environmental factors (Diskin and Morris, 2008;Catunda et al, 2013). The BCS or body fat reserves are significant effective factors affecting reproductive performance, especially altering or regulating basic hormones that affect the ovulation rate, fertility, and the implantation and maintenance of gestation (Catunda et al, 2013;Boudreau et al, 2014;González-García et al, 2015).…”

Abstract. The present study was planned to determine the effect of ewe body condition score (BCS) and parities on fertility, return rate, gestation length, fecundity, litter size and lamb birth weight. Data were collected from 284 heads of ewes with first to fifth parity and raised at a state farm for three consecutive (2002)(2003)(2004) years. Teaser rams were used to monitor estrus twice daily in the morning and in the evening from September to October. BCSs and body weights (BWs) were recorded at mating and postpartum. The ewes, at mating time in breeding season and within first 6 h after the expulsion of fetal membranes, were divided into four groups on the basis of their BCS: thin (BCS = ≤ 2.0; n = 70; 38), medium (BCS = 2.5-3.0; n = 122; 142), fat (BCS = 3.5-4.0; n = 72; 59) and very fat (BCS = ≥ 4.5; n = 20;17). BCSs and BWs of ewes at postpartum were highly correlated with lamb birth weight (R = 0.486, P < 0.01, and R = 0.130, P < 0.05, respectively). BCSs and BWs of ewes at postpartum had positive effects on lamb birth weight (Y = 3.43 ± 0.10 + 0.130 + 0.047 ewe body condition score (EBCS), P < 0.01; Y = 2.92 ± 0.42 + 0.018 ± 0.009 ewe body weight (EBW), P < 0.05 kg of lamb birth weight per BCS and kilogram of ewe live weight, respectively). The fertility rate, litter size and fecundity were higher in the medium and fat groups than thin and very fat groups (χ 2 = 10.607, P < 0.01). The BW and BCS at postpartum affected gestation length positively (P < 0.05). Return rate or number of coitus for conception were higher (P < 0.05) in thin and very fat groups than medium and fat groups. The data revealed that the ewes with medium and fat body condition (BCS = 2.5-4.0) scores were profitable.

“…Ruminants absorb little glucose and have no glucokinase activity in the liver, and nearly all of their glucose needs must be compensated by gluconeogenesis. Propionate is the principal source of carbon for glucose synthesis in liver, which meets 85%-90% of the body glucose requirements in sheep (Catunda et al, 2013;Watanabe et al, 2014). Alfalfa hay had a more effective role than sodium propionate on calf performance and rumen development (Beiranvand et al, 2014).…”

Grasses and legumes are two groups of plants physic and chemically different (amount of crude protein and fiber, mostly), very used in animal feed, whose differences can determine variation in intake, digestibility and animal behavior. We aimed to evaluate performance, feeding behavior and the serum biochemical profile of sheep. The treatments were four levels of substitution of Bermuda grass (Cynodon dactylon [L.] Pers.) hay for alfalfa (Medicago sativa L.) hay (0, 330, 660 and 1000 g kg -1 DM). The randomized block design was used being two blocks and four treatments with 10 replicates). There were no effects on the performance of animals. On the other hand, there was a positive linear effect (P < 0.05) for intake of DM, organic matter, crude protein (CP), total carbohydrates, and non-fibrous carbohydrates. However, the use of neutral detergent fiber (NDF) showed linear decrease with the increase in alfalfa hay (P < 0.05). CP and NDF decreased linearly (P < 0.05) with the replacement of Bermuda grass hay for alfalfa hay. There were decreasing linear effects (P < 0.05) when compared to the time of ingestion and chewing of feed, and increasing linear effects regarding total resting time. Estimated passage rate, density of particles and blood glucose showed a positive linear effect (P < 0.05), while weight of gastrointestinal contents decreased according to alfalfa levels (P < 0.05). The replacement of Bermuda grass hay by alfalfa hay to promote improvement in the performance is not recommended.Key words: Behavior, digestibility, intake, legumes, Medicago sativa.
