Fatty acid profile and sensory properties of lamb meat from males of five indigenous breeds

The objective of this study was to determine meat quality characteristics, fatty acid profiles, and sensory characteristics of 50 single-birth male lambs from five breeds: Artli (n = 10), Cepni (n = 10), Hemsin (n = 10), Karayaka (n = 10), and Of (n = 10). At the beginning of the experiment, the average age and weight of the lambs were 120 +/- 5 d and 30.7 +/- 0.68 kg respectively. After 60 d of intensive fattening, the average live weight before slaughter was 40.96 kg +/- 0.76 kg. All evaluations were performed on samples from the longissimus thoracis et lumborum (LTL) muscle. There was no difference between breeds in terms of the pH values of the hot carcasses, whereas the cold carcass pH values were higher (P<0.001) in Hemsin animals than in the other breeds. Meat chemical properties (such as organic matter; dry matter; and fat, measured as the ether extract), physical properties (such as cooking loss; drip loss; and water-holding capacity, WHC), and instrumental values (such as colour, L* and b* values, chewiness, hardness, and resilience) were significantly affected by breed differences. Additionally, the differences between breeds were found to be significant in terms of the fatty acid composition and the evaluation of organoleptic properties, such as sensory characteristics, flavour, and juiciness of cooked (boiled or roasted) meat. The results show that lamb meat's physical, chemical, and sensory properties vary by breed. The differences found in the composition and presence of meat fatty acids between and within breeds can be used as a source of variation for future genetic improvement strategies

Comparison of the Body Condition Score and Body Measurements of Purebred and Crossbred Kids Fattening in Different Systems

In this study was aimed to crossbred male kids of the Hair goat and Saanen x Hair kids (G1) body condition score and compare their body size intensive, semi-intensive and extensive conditions. In the research, 30 Hair goat and 30 Saanen x Hair goat (G1) crossbred single male kids was used. When the research findings were evaluated, in terms of body condition scores of 30, 60 and 90th days high values in the semi-intensive were detected in fattening Saanen x Hair goat (G1) crossbred kids. However, at the end of fattening in semi-intensive fattening group of Hair goat it is determined that the value of the highest condition score. This situation is thought to be caused by more growth of environment and width measurements in Hair goat kids in the later stages of fattening according to the Saanen x Hair goats (G1) crossbred. In study in terms of body length during whole fattening, in terms of the height at the withers data obtained from the 60th and 90th day was found statistically significant. At the end of the fattening in semi-intensive fattening group of Saanen x Hair goat (G1) crossbred it was observed to have higher body length and height at the withers value of crossbred kids. When chest width measurements between paddles in kids were examined, in all periods seems to be an increase in Hair goat kids than the Saanen x Hair goat (G1) crossbred kids. At the end of fattening in terms of height rump Hair goats has shown higher values than Saanen x Hair goat (G1) crossbred kids but the highest values of the semi-intensive group has shown. As a result, semi-intensive feeding group of kids of body condition score and body size was higher than intensive and extensive fattening group kids, in terms of length and height measurements Saanen x Hair goat (G1) crossbred kids in terms of width and environmental measures has shown higher values than Hair goat kids

Comparison of Saanen x Hair Goat Crossbred (F1, G1) and Hair Goat Raised at The Farm Conditions in Terms of Milk Yield Characteristics

This study was conducted to determine milk yield characteristics and its effect on genotypes, years and ages Hair goat x Saanen crossbred and Hair goat breed between 2011-2012 years in private enterprise which is located in Amasya province Sarılar village. In this study, the effect of genotypes was found significant on average daily milk yield, lactation length and lactation milk yield in 2011 and 2012 years. In 2011, the effect of goat ages were determined on average daily milk yield (ADMY) and lactation milk yield (LMY) for all goat genotypes. In 2012, the effect of goat ages was determined on average daily milk yield and lactation length (LL) for all goat genotypes. The effect of year F1 and Hair goat were found significant on ADMY, LMY, and LL. The effect of year was found significant on only LL for G1 genotype. As a result it can be say that Saanen goat x Hair goat crossbred F1 and G1 genotype milk yield was higher than Hair goat reared in farmer conditions

Comparison of Kil Goat and Saanen x Kil Goat Crosbred (F1, G1) Raised At The Farm Conditions In Terms of Fertility Characteristics

This research Amasya Sarilar (40°54'23"N, 35°08'min5"E), a private business in the years 2011-2012 between the grown Saanen x Kil goat crosbred (F1, G1) and Kil goat in the fertility characteristics to detect and genotype on these features, year was conducted to determine the effects of such factors. In the study of reproductive traits for the year 2011 only twin goats giving birth rate among genotypes were found statistically difference. The twin birth rate of Kil goat was similar in F1 crosbred and G1 is different from both genotypes were found. In 2012, the remaining infertile among genotypes goat, dead goat giving birth and twin goats rate has been determined that there are statistical differences. Infertility rate, Saanen x Kil goat F1, G1 crosbred was found to be higher than in the Kil goat. Twin goat giving birth rate F1 genotypes in high, genotypes G1 and Kil goats find similar

Determining Potential Feed Value and Silage Quality of Guar Bean (Cyamopsis tetragonoloba) Silages

This study was carried out to determine the effects of some additives on the potential nutritional value and silage quality of guar bean (Cluster bean = Cyamopsis tetragonoloba) silages. It was hypothesized that the use of cereal grains, molasses and ecomass will reduce silage fermentation pH by increasing lactic acid production and positively improve CP content and silage quality. Four different silage groups were established; (control, grain (5%), molasses (10%) and ecomass+molasses (10%+5%)). Fresh guar beans were thoroughly mixed with the additives to homogenize, then ensiled and opened after 60 days. The results of this study revealed that guar bean silages could be used as an alternative forage in ruminant feeding because of its higher protein content (13.88%), forage feed value and silage quality. The use of molasses (GSM) and molasses + ecomass (GSEM) as additives has significantly (P ≤0.01) increased the silage quality and feed value compared to the control group. It was observed that GSM and GSEM silage groups had the highest values in terms of lactic acid content. In conclusion, guar silage can be used as an alternative feed for ruminants, but the doses of barley and molasses should be correct and tested in in vivo studies

Determination of the In Vitro Gas Production and Potential Feed Value of Olive, Mulberry and Sour Orange Tree Leaves

This study was conducted to determine the potential nutritive value and in vitro gas production (IVGP) parameters of Olea europaea L. (Olive = OL), Morus alba L. (Mulberry = ML) and Citrus aurantium L. (Sour orange = SOL) tree leaves. Hohenheim gas test was used to determine the in vitro gas productions of the leaves. The gas production of samples over time was recorded for 3, 6, 9, 12, 24, 48, 72 and 96 h after incubation. Completely Randomized Design was used to compare gas production, and gas production kinetics of samples. The findings of the present study suggested that there were differences among the tree leaves in terms of crude protein, NDF, in vitro gas productions, organic matter digestibility (OMD), metabolisable energy (ME), net energy lactation (NEL) and relative feed values (RFV) (P<0.01). ML had the highest condensed tannin contents (P<0.05), in vitro gas production (IVGP), OMD and energy values (P<0.01). SOL had highest RFV values. OL showed the lowest IVGP when compared to SOL and ML. Low NDF and ADF contents of SOL would probably increase the voluntary intake, digestibility and relative feed values of these leaves by ruminants. In conclusion, it was determined that OL, ML and SOL used in the study have low in vitro gas production and can be utilized as alternative roughage feed in ruminants. However, it is recommended that the results obtained from this research should be tested in in vivo studies
