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.

The Effects Of Electrical Stimulation On The Sensory And Textural Quality Properties Of Mutton Carcasses, Mete Yanar, Hasan Yeti̇m

Turkish Journal of Veterinary & Animal Sciences

The objective of this research was to investigate the influence of electrical stimulation (ES) on the sensory and textural quality characteristics of mutton carcasses from elderly ewes. For this purpose, 14 ovine carcasses from 3-5-year-old ewes were subjected to ES with 350 V, and the effects of ES on the organoleptic and instron textural parameters were evaluated. The ES significantly (P < 0.01) improved the panel tenderness scores of the Longissimus dorsi (LD) muscle. Some of the Instron Warner Bratzler Shear parameters such as peak force and initial yield force values of the LD muscle were also highly significantly (P < 0.01) affected by ES, while the Semimembranosus (SM) muscle was not affected. Hardness and peak force 2 values of LD obtained from the Instron compression test were also significantly (P < 0.05) affected by ES. However, Instron compression parameters of SM muscles were not significantly influenced by ES treatment. The results revealed that the ES could considerably improve the tenderness of the LD from mutton carcasses. In conclusion, the application of ES to mutton carcasses from elderly ewes could be beneficial for the meat industry by increasing the merchandising value and quality of this sort of carcass.

Behaviour And Biological Control Of Bacteriocin-Producing Leuconostocs Associated With Spoilage Of Vacuum-Packaged Sucuk, Özlem Osmanağaoğlu Jan 2003

Behaviour And Biological Control Of Bacteriocin-Producing Leuconostocs Associated With Spoilage Of Vacuum-Packaged Sucuk, Özlem Osmanağaoğlu

Turkish Journal of Veterinary & Animal Sciences

Non-motile, Gram-positive and catalase-negative anaerobic Leuconostoc sp. were found to be involved in the spoilage of vacuum-packaged refrigerated sucuk samples. The spoilage was associated with an accumulation of large quantities of foul-smelling gas and purge in the bag and loss of colour and texture in the meat. Many of these isolates produce bacteriocins, to which the predominant Gram-positive bacteria normally found in these products are sensitive. As the leuconostocs grew at low temperatures and produced bacteriocins, they inhibited the growth of associated sensitive bacteria. Attempts to inoculate purge from spoiled samples into fresh meat, vacuum packaging and refrigeration storage facilitated …

Glycobiology Current Molecular Biology, Sabi̇re Karaçali

Turkish Journal of Veterinary & Animal Sciences

Carbohydrate chemistry evolved into carbohydrate biochemistry and gradually into the biology of carbohydrates, or glycobiology, at the end of the last century. Glycobiology is the new research area of modern molecular biology, and it investigates the structure, biosynthesis and biological functions of glycans. The numbers, linkage types (\alpha or \beta), positions, binding points and functional group differences of monosaccharides create microheterogeneity. Thus, numerous glycoforms with precise structural differences occur. Each glycoform as a distinct biological ligand has a different function. Studies in glycobiology have concentrated on determining molecular structures and glycosylation mechanisms, investigating biological control mechanisms and the phenotypic characteristics …

Cattle Rumen Tissue Arginase And Molecular Weights Of Its Subunits, Mi̇ne Eri̇şi̇r, Sema Temi̇zer Ozan

Turkish Journal of Veterinary & Animal Sciences

The arginase was partially purified from cattle rumen tissue and its properties were investigated and thereafter compared with those of other tissue arginases. The specific activity of the purified enzyme was found about 150 times greater than that of the crude rumen homogenate. The molecular weight of native arginase, estimated by gel filtration on a Sephadex G-150 column, was 122 500 ± 2500 and those of subunits of the enzyme, estimated by SDS-PAGE and gel filtration on a Sephadex G-100 column, were 44 000 ± 1000 and 34 500 ± 500. This indicates that the native enzyme is a trimer …

The aim of this study was the determination of vitamin losses and sensorial quality in the liquid and traditionally smoked canned mussel. Liquid and traditionally smoked black mussels were sterilized at 120 ± 1 °C F_0 5.2 ± 0.1 min in three different sauces (tomato puree sauce, curry sauce and oil sauce). Thiamin losses in liquid and traditionally smoked canned mussels were determined. No significant change was determined in riboflavin levels in the smoked canned mussel. It was determined that different sensorial properties were linked to the sauce applied. It was also determined that traditional smoking significantly contributes to the …
