Abstract. The purpose of the research was to study growth, carcass traits and meat quality of Kara, Yesilbas and Boz ducks (as the local names), in comparison with Turkish Pekin ducks in Isparta province, Turkey. Average body weights of Kara, Yesilbas, Boz and Turkish Pekin ducks were 42.3, 44.5, 48.0 and 46.2g for day-old ducklings; 1036.5, 1154.5, 1115.3 and 1168.7g for 4 weeks old ducklings; 1660.7, 1824.7, 1894.0 and 1744.2g for 8-week old ducks; 1816.0, 1999.0, 2044.0 and 1885.5g for 12-week old ducks, respectively. Average percentages of slaughter yield were 71.5, 72.5, 73.7 and 71.3%. The percentages of breast and leg meat to the carcass were 34.34, 34.1, 33.8, 36.7%, respectively. Average percentages of crude protein content for breast and leg meat were 20.2, 20.0, 20.3, 20.7% and 20.1, 19.4, 18.8, 19.4%, respectively. The content of crude fat for breast and leg meat were 10.3, 5.8, 8.3, 14.9% and 10.6, 6.4, 8.9, 15.1% respectively. Because of the lower fat percentage, the local duck breeds could be important for a commercial crossbred program.

Abstract. In this study; the growth, carcass traits and meat quality were determined in Bronze and White turkeys, in comparison one another in Isparta province of Turkey. Average of body weights of bronze and white turkeys were 7495–4843g and 15844–11797g; average percentages of carcass were 74.0–71.2% and 82.7–81.9%; average percentages of crude protein content of muscle meat of breast, legs were 23.0–26.1%, 19.0–21.2% and 16.5–17.4%, 13.3–14.8% at the age of 18-weeks, respectively. Significant differences were determined (P < 0.05) between genotypes of body weights, carcass traits, meat qualities, and also between males and females of genotypes.

Abstract. The studies were conducted on 200 Muscovy ducks, 100 Pekin ducks of the A-44 strain and 200 their crossbreeds (sex ratio: 1:1). The ducks were fed complete commercial diets, appropriate for respective species. Slaughter and slaughter value estimation were performed at the age of: 7 weeks – for males and females of the A-44 strain, 10 weeks – for Muscovy females, and 12 weeks – for Muscovy males and crossbreeds (♂ and ♀). Analysis of the chemical composition, physicochemical properties and sensory properties of meat was made on breast muscles. The heterosis effect on the slaughter value and meat quality was additionally estimated in hybrids. The highest live body weights were reported for Mucovy drakes (4450 g), and the lowest – for ducks from this genetic group (ca. 2400 g). The crossbreeds were characterized by average body weights (2980 g), but the highest relative meatiness (ca. 54%) and the lowest fatness (ca. 20%) of carcasses. The best sensory properties were reported for muscles of ducks of the A-44 strain. A favorable heterosis effect was observed in crossbreeds: positive in relation to meatiness and negative in relation to fatness, undesirable in the customers’ opinion. No favorable heterosis effect was noted in most meat quality traits.

Abstract. The local goose breeds Kara, Beyaz, Şam, Ala and Tülü of the Isparta province in Turkey are relatively small with body weight at the age of 12 weeks for males-females of 2864.1–2593.1, 2588.5–2296.8, 3004.3–2504.3, 2601.9–2264.0 and 2754.7–2352.0 g. The average percentages of slaughter yield of Kara, Beyaz and Şam geese at the age of 104 weeks for males-females were 71.4–69.8, 71.6–69.9 and 71.0–69.3%. The percentages of breast and leg to the carcass were 46.6–48.4, 48.7–50.2 and 47.1–48.3%, respectively. Average percentages of crude protein content for breast and leg muscle were 19.7–20.1, 22.0–20.3, 18.2–18.0% and 15.8–18.0, 21.7–16.2, 17.7-19.8%, respectively. The content of crude fat for breast and leg muscle were 0.23–0.49, 0.39–0.40, 0.44–0.40% and 0.92–1.41, 0.39–1.31, 0.46–0.33%, respectively. Because of the lower fat percentage, the local goose breeds could be important for a commercial crossbred program.

The objective of this study was to evaluate the effects of the association of cottonseed processing method with chitosan on carcass traits and meat quality of lambs finished in feedlot. Eighty lambs with an average body weight of 20.6 kg, with 04 months of age, were distributed in a completely randomized design, in a 2 x 2 factorial arrangement. The factors were represented by two cottonseed processing method (whole or ground) and two levels of chitosan (0 and 136 mg/kg BW). The association of cottonseed processing method with chitosan in the lamb diet did not affect (P>0.05) carcasses traits. The pH, color, cooking losses, shear force, and proximate composition of meat were also not affected (P>0.05) by the processing method of cottonseed or its association with chitosan in the lamb diets. There was an increase in palmitoleic (c9-C16:1; P = 0.01) and conjugated linoleic (P = 0.02) fatty acids when ground cottonseed was associated with chitosan. Ground cottonseed associated with chitosan increases the concentration of unsaturated fatty acids in the meat of feedlot lambs.

Abstract This study evaluated the effect of roughage:concentrate (R:C) ratio associated with a variable particle size of physically effective neutral detergent fibre (peNDF8) in the forage (Tifton-85 hay) on the performance, carcass traits and meat quality of lambs. Seventy-two 4-month-old, non-castrated Santa Ines male lambs (23.5 ± 2.32 kg BW) were distributed in a completely randomized design, in a 2 × 2 factorial arrangement [two peNDF8 hay particle sizes (13 and 6 mm) and two R:C ratios (700:300 and 500:500 g/kg DM total)]. DMI, DM, NFC and TDN digestibility's, N-intake and N-faecal excretion were affected by the R:C ratio (P < 0.05). However, the N-retained was not affected by the studied variables (P > 0.05). It was observed an interaction (P < 0.05) between the peNDF8 and R:C ratios for final BW, average daily gain (ADG), colour parameters and pH 24 h. The lower roughage ratio provided greater (P < 0.05) concentrations of C14:1, C16:1–cis9, C18:1–cis9, ΣMUFA, Σn–6:Σn–3 and hypocholesterolemic/hypercholesterolemic index, enzymatic activity Δ9desaturase-C16 and -C18. Lambs fed a lower roughage diet had improved performance and feed efficiency, however, presented reduced polyunsaturated fatty acids (PUFA) concentrations in the meat, especially Σn–3 family. Higher roughage diet and larger peNDF8 particle size improved the concentrations of PUFA while decreased Σn–6:Σn–3 ratio in meat. Larger peNDF8 particle size associated with higher roughage proportion, have reduced animal performance however, it increased protein concentration, a* and C* colour parameter without affecting fatty acids profile of Longissimus lumborum muscle.

A study was conducted to the determine the effects of concentrate supplimentation on performance and nutrient digestibility in cane-rats/grasscutters. There were initiall three treatments: 0%, 10% and 20% concentrate supplementation onas fed basis to a basal elephant grass diet. Fifteen weaned cane-rats with average body weights of 1150g(士365.40) were randomly assigned to the three treatments based on weight and sex. The growth study was conducted for eight weeks. A nutrient digestibility study was also conducted using three grasscutters per treatment. The cane-rats fes 20% supplementary concentrate gained more weight than those offered 10% concentrate feed. Crude protein was better (p<0.05) digested by cane-rats on 20% concentrate feed whereas, ash and ether extract digestibility were better on 10% concentrate feed. The 0% concentrate treatment was terminated because three of the cane-rats(68% mortality) died within three weeks of the study. It is recomendedfrom this study that cane-rats fed a basal grass diet should be supplemented with 20% concentrate on as fed basis
