ABSTRACTTwo experiments are described investigating the possibility of advancing puberty in Awassi ewe lambs kept under semi-arid conditions in mid Syria using 197 single ewe lambs in 1982 and 165 in 1984. In both years, the animals were allocated to three groups each given different levels of supplementation with a barley/chopped straw mixture to achieve different levels of pre-mating growth (high, medium and low). In 1984, the three groups were further subdivided into four subgroups each given continuous exposure to teaser rams from different ages. These were 175, 200 and 230 days of age and a control group not given continuous access to the ram. The results for the two experiments showed that a higher proportion of ewe lambs on the high and medium treatments showed oestrus in their first season (H = 88%, M = 72%, L = 41%; P < 0·01). The high level of nutrition also advanced the mean date of first oestrus in the high group by 22 and the age at conception by 16·5 days as compared with the low level.In the second experiment, no interaction between feeding level and presence of ram was observed and although there were no significant effects on occurrence of oestrus, continuous exposure to vasectomized rams from 175 days reduced mean age at first oestrus by 16 and age at conception by 19 days as compared with the unexposed controls.It is concluded that these practices have important implications for the efficient use of semi-arid range land by Awassi sheep on a semi-intensive system.

Abstract The current study was carried out on a poultry farm which belongs to the Animal production department - College of Agriculture - University of Kufa,for a period of 35 days, start from October 10 to November 13, 2020, for 5 weeks to find out the effect of adding different levels of turmeric root powder and carnation flowers to the diet on some productive traits of broilers. In this experiment, 360 broiler chicks were used, a one-day-old Ross-308 hybrid. Chicks were divided randomly into 6 treatments (60 chick/treatment). Each treatment had 3 replicates with 20 chicks each.These replicate included 20 chicks with an initial average weight of 40gm and the treatments were as follows: 0, 3, and 5 gm/kg diet of turmeric root powder for T0, T1, T2, as well as 3 and 5 gm/kg diet of carnation flower powder for T3 and T4, respectively, and T5 contained 4 gm/kg diet fodder mix of both turmeric root powder and carnation flowers. Chicks were exposed to Cyclical day temperature. Results showed a significant increase (P<0.01) in the total body weight average in T2 and T5 Compared with T0, T1, and T3. Total weight gain increased significantly in T5 (P<0.01) compared to T0, T1, T2, T3, and T4.Also, results showed a significant increase (P<0.01) in the total feed consumption ratio in T1, T2, T4, and T5 compared to T0 and T3. In addition, thetotal conversion coefficient for the birds showed a significant increase (P<0.01) in T4 and T5 by showing the lowest value 1.58 for both treatments compared to T1 and T3(1.64, and 1.62), respectively.

SUMMARYThe performance of Suffolk cross-bred ewe lambs produced either by Suffolk crossbred ewes, 70–90% Suffolk (HS), or by Ossimi ewes, 35–45% Suffolk (LS), was investigated. Forty-three ewe lambs from both groups were available, and were given two different levels of feeding.The LS ewe lambs showed, insignificantly, better growth performance than the HS group, and breed group differences increased with age. They also reached puberty earlier (305·4 v. 334·6 days for the HS ewe lambs). Using the HS breeding rams rather than the imported Suffolk ones, for improving lamb production from the local sheep flocks, is recommended.The LS ewe lambs started their first breeding season 18 days earlier, and ended 34 days later, than the HS ewe lambs. Both cross-bred groups showed clear anoestrous periods of 225·4 and 202·2 days, respectively. The onset of their second breeding season was similar, on average 29 August. These figures are close to those of the purebred Suffolk ewes, and far away from the nonseasonal local parents.

The research was conducted to investigate the effect of different levels of rosemary powder supplementation  on some productive traits of broiler chicken ross strain. Three hundred unsexed broiler chicks of one-day-old were equally divided into five groups, 2 replicates per group (30 chicks per replicate). Chicks were fed on starter diet from one-day-old until end of three weeks then replaced to finisher diet from the beginning of four weeks until the end of six weeks, starter and finisher diet supplemented with four ratios from rosemary powder 0, 0.5, 1, 1.5 and 2% which represented experimental groups.                                                        Results showed a significant superiority (P≤0.05) in average live body weight, weight gain, feed conversion ratio and dressing percentage in birds supplemented with rosemary powder as compared with control group at 3 and 6 weeks of birds age. Moreover, supplementation of rosemary had significantly (P≤0.05) decreased mortality ratio in experimental groups as compared with the control group.                                            It can be concluded that supplementation of rosemary powder to the diet had a profound effect to enhance productive traits of broiler chicken ross strain.
