The Effect Of Different Rations On Some Rumen Fluid And Blood Parameters In Sheep, Taylan Aksu, Suphi̇ Deni̇z
Turkish Journal of Veterinary & Animal Sciences
The objective of this study was to evaluate the effects of different combinations of energy (barley and dried molassed sugar beet pulp (DMSBP)) and protein sources (soybean meal (SBM), cotton-seed meal (CSM), SBM-treated with formaldehyde (FTSBM), CSM-treated with formaldehyde (FTCSM), and urea) on some rumen fluid and blood parameters. In this study, four rumen fistulated Morkaraman rams were used. Rumen pH values were around the optimal pH values suggested for rumen fluid (5.2-7.3) at all sampling times. Ruminal NH_3-N concentrations were significantly greater (P < 0.05) in animals fed DMSBP as an energy source compared with animals fed barley as an energy source and were between 10.4 and 32.75 mg/100 ml in all groups. Formaldehyde treatments of protein sources reduced ruminal NH_3-N concentrations in animals fed DSBP as an energy source (P < 0.05). Acetic and propionic acid concentrations were affected by the energy source, although butyric acid concentrations were significantly higher in animals fed groups containing barley than in animals fed groups containing DMSBP. Formaldehyde treatment did not affect propionic acid concentrations, although propionic acid concentrations were generally significantly higher (P < 0.05) in animals fed barley + SBM combinations compared to treatments containing both SBM and CSM combinations (P < 0.05). Serum total protein concentrations were affected by the energy source and these were higher in groups containing DMSBP than in groups containing barley (P < 0.05). However, serum urea-N concentrations were similar among the different diets.

Growth And Carcass Characteristics Of Three Fat-Tailed Pure Breeds Under Grazing With Concentrate Supplementation, Muhli̇s Maci̇t, Sirri Şahi̇n, Nuri̇ni̇sa Esenbuğa, Mevlüt Karaoğlu
Turkish Journal of Veterinary & Animal Sciences
Growth performance, carcass measurements and carcass characteristics of three fat-tailed Turkish breeds (Awassi = A, Morkaraman = M and Tushin = T) weaned at 2.5 months of age and subjected to semi-intensive feeding during a grazing period on pasture for 70 days were evaluated. At the end of the 70-day grazing period, M lambs showed the highest performance for daily weight gain and the amount of concentrate consumed per bodyweight gain in addition to grazing on pasture. The effects of the breed and sex of lambs on daily weight gain on pasture were significant (P < 0.05) and highly significant (P < 0.01), respectively. Male lambs were superior to female lambs with respect to daily weight gain on pasture. The slaughter traits, carcass measurements and carcass characteristics of 14 male lambs representing three fat-tailed breeds were compared at the end of the grazing period of the year in which they were born. After slaughter, carcasses were chilled at +4 °C for 24 h and measurements were taken on the intact cold carcasses. The carcasses were then dissected into wholesale cuts. The hot carcass weight and hindshank weight of M lambs were heavier than those of A and T lambs. M had a higher hot dressing percentage and larger M. longissimus dorsi (LD) area than those of A and T lambs. Most of the weights of wholesale cuts such as foreshank and breast, sirloin, leg, rib and hindshank were significantly (P < 0.05; P < 0.01) affected by sheep breed. It is recommended either that A, M or T male and female lambs weaned at 2.5 months of age in eastern Turkey should be fed with 450 g concentrate per head per day on pasture for 3 to 3.5 months of grazing season, or lambs should be supplemented with more than 450 g concentrate feed on pasture because native fat-tailed Turkish breeds supplemented with 450 g concentrate on pasture did not give carcasses with an adequate commercial weight at the end of a 70-day fattening period.

Skeletal muscle development in avian embryos depends on the activation, proliferation, differentiation, and fusion of embryonic myoblasts. These processes as well as early embryonic development are mainly regulated by major growth factors such as IGF-I, IGF-II, TGF-b and FGFs. In order to determine their differential expression, total RNA was isolated from whole embryos on each of the embryonal days (E) 0 to 6, from the thoracic/abdominal half of the embryo at E 7 and E 8, and from pectoralis muscle tissues at E 9 to E 20. Growth factor cDNAs were synthesized by reverse-transcription polymerase chain reaction (RT-PCR). All growth …
