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.

In this study, serum thyroid hormone, glucose and urea levels as well as blood pH values were compared between six control (birthweight ? 2.5 kg) and seven experimental Merino lambs (birthweight < 2.5 kg, hypotrophic) at 2, 4, 8 and 24 h postpartum. Serum levels of total thyroxin (T_4), free thyroxin (FT_4), total triiodothyronine (T_3; with exception of 24 h postpartum), free triiodothyronine (FT_3; with the exception of 4, 8 and 24 h postpartum) and glucose were lower in hypotrophic lambs compared to the controls. However, the serum urea levels of hypotrophic animals were higher than those of the controls. On the other hand, serum T_3, FT_3 and FT_4 levels determined at 4 and 8 h were higher than those at 2 and 24 h postpartum in both groups. A similar case was also observed in the serum T_4 levels of hypotrophic lambs. In addition, the serum glucose levels of hypotrophic lambs were higher and the blood pH values of both groups were lower at 2 h postpartum. In conclusion, It was observed that low birthweight affected neonatal thyroid function, serum glucose and urea levels in lambs.

Conditions for premature delivery were established by giving a salt-rich diet and administering oxytocin to induce high-risk pregnancy. In order to avoid early delivery, a betamimetic ritodrine and the Ca^{++} channel blockers nitrendipine and nicardipine were administered to three separate groups. The effects of these three tocolytic agents were examined by determining serum oestradiol and progesterone levels. Additionally, systolic blood pressure was measured and tachycardia was observed. After the administration of tocolytic agents, it was observed that serum oestradiol levels were increased while there was a decrease in …

This experiment was carried out to evaluate the effects of formic acid and formic acid plus molasses additives on the grass silage fermentation characteristics and degradability of dry matter (DM) and acid-detergent fibre (ADF). Grasses were cut in early (experiment I), middle (experiment II) and late maturity (experiment III). The additive treatments in experiments I, II and III were: 1) Untreated; 2) 0.5% Formic acid (FA); 3) FA+2% molasses; 4) FA+4% molasses; and 5) FA+6% molasses. The silages were ensiled in jar silos (1 L) and DM and ADF degradability were determined by using the nylon bag technique in the …
