The Effect of Different Rations on Carcass Characteristics in Sheep Castrated With Elastrator or Immunization Against Lhrh Using Fusion Protein Ovalbumin-Lhrh 7
(Medwell online, 2009) Budag, Cemal
The aim of this study was to investigate the effects of poor and rich rations on carcass characteristics in sheep actively immunized against LHRH using ovalbumin-LHRH-7 fusion protein. Thirty ram lambs at 19 weeks of age were used in 1 (immunized, n = 10), E (castrated with elastrator, n = 10) and C groups (intact, n = 10). Animals in 1 group were immunized against LHRH using ovalbumin-LHRH-7 (OL) protein generated by recombinant DNA technology as a primary and a booster injection at 19th and 23rd weeks of age respectively. Each group was divided into 2 subgroups (11, n = 5; 12, n = 5; El, n = 5 and E2, n = 5; Cl, n = 5; C2, n = 5) in the 31st week of the birth. Animals were housed in groups and fed with their rations for 6 weeks. The animals in the Cl, 11 and El groups were fed with low protein and energy ration (RI; 11.3% CP, 2290 Kcal kg(-1) ME), whereas in the groups C2, 12 and E2 were fed with high protein and energy ration (RII; 16.2% CP, 2438 Kcal kg(-1) ME). Rations were enriched with vitamins and minerals. At the end of the feeding period, all animals 41 weeks old were slaughtered. The results showed that testis weights and rates of the C groups were different from 1 end E groups both in RI and RII (p<0.05). However, castration with immunization or elastrator reduced testis weight. Lamb chop, internal fat, testis, back-lion, forearm, shoulder and neck weights in C group in RI were different from those in I and E groups (p<0.05). Forearm in C; lamb chop in 1, E and C; bone weights in I were different between RI and RII treatments (p<0.05). Neck in I, E and C; internal fat rates in I, E and C were different in RI (p<0.05). Kidney and pelvic fat in 1, E and C; neck in I, E and C; internal fat rates were different in RII (p<0.05). Pre-slaughtered live weights; warm and cold carcass weights; dressing percentage of the C group appeared to be higher than other groups in RI and RII, but these differences were not significant.
The Effect of Gender, Genotype, Dam Age, Birth Year and Birth Type on Birth Weight: Norduz and Karakas Lambs
(Medwell online, 2008) Karakus, Kadir; Budag, Cemal; Tuncer, S. Seckin; Ozdemir, Taner; Eyduran, Ecevit
The present study was conducted to determine the effects of several environmental factors on 572 lambs (229 Karakas and 343 Norduz) raised at Research and Application Farm of Agricultural Faculty, Yuzuncu Yil University, Van, Turkey. In this study, birth type (single and twin), gender (male and female), dam age at lambing (1, 2, 3, 4, 5, 6 and 7) and birth year (2004, 2005, 2006 and 2007) and birth weights (kg) of Norduz and Karakas Lambs were recorded. According to results obtained from the present study, genotype factor on birth weight of Norduz lambs was non-significant, the influences of gender (p<0.001), dam age (p<0.01), birth type (p<0.001) and birth year (p<0.001) on it were found significant. As a result, the birth weight trait provides useful information for early selection criteria in breeding program.
Effects of Chickling Vetch (Lathyrus Sativus L.) Grain as Feed on Certain Blood Parameters in Lambs
(Medwell online, 2009) Budag, Cemal; Tas, Abuzer; Vakit, A. Semra
In the present study, effects of use of Chickling Vetch (CV) grain feed, which is one of leguminous grain feeds, at different levels on certain blood parameters in lamb rations were investigated. Twenty four of weaned female lambs, which are approximately 16 weeks old, were used for the test. Three feeding groups were established for the test. According to it, feed amount, which accounts for 2% of Body Weight (BW), consists of completely dry trefoil for the Control group (C). The second group (CVI) was fed with chickling vetch in an amount of 0.75% of BW and Dry Trefoil (DT) in an amount of 1.25% of BW and the third group (CVII) was fed with chickling vetch in an amount of 1.5% of BW and dry trefoil in an amount of 0.5% of BW. Two blood samples were collected from the lambs, one was collected at the beginning of the study and the other was collected on the 25th day of the study. According to the analysis conducted, it was observed that blood Aspartate Aminotransferase (AST) level decreased in all groups including control groups, while Blood Urea Nitrogen (BUN) levels increased of in CVI and CVII groups depending on CV diet (p<0.05). However, blood Triglyceride (TG), Very Low Density Lipoprotein (VLDL), blood Albumin (ALB), blood Globulin (GLO), blood alanine Aminotransferase (ALT) and Lactate Dehydrogenasis (LDH) levels in the bloods of the lambs were not affected by CV-type diet. The fact that use of CV, which is a good protein and energy feed, increased BUN suggested that a pore protein metabolism was formed in the animals. High ratio use of CV containing anti-nutrient materials like all leguminous grain feeds, was expected to increase ALT, AST and LDH levels; however, it were not caused any changes in ALT and LDH parameters also it decreased AST levels. This evidenced positive effect of CV on liver.

In the present study, effects of use of vetch grain feed (V), which is one of leguminous grain feeds, at different levels on certain blood parameters in lamb rations were investigated. Twenty four of weaned female lambs, which are approximately, 16 week old, were used for the test. Three feeding groups were established for the test. According to it, feed amount, which accounts for 2% of Body Weight (BW), consists of completely dry trefoil for the Control group (C). The second group (VI) was fed with vetch in an amount of 0.75% of BW and Dry Trefoil (DT) in an amount of 1.25% of BW and the third group (VII) was fed with vetch in an amount of 1.5% of BW and dry trefoil in an amount of 0.5% of BW. Two blood samples were collected from the lambs, one was collected at the beginning of the study and the other was collected on the 25th day of the study. According to the analyses conducted, it was observed that blood Triglyceride (TG), Very Low Density Lipoprotein (VLDL) and Lactate Dehydrogenasis (LDH) levels in the bloods of the lambs were not affected by V-type diet. However, blood Aspartate Aminotransferase (AST) level increased in all groups including control, while blood Albumin (ALB) level increased in VII depending on Vetch (V) diet (p<0.05). It was also, seen that blood alanine Aminotransferase (ALT) and Blood Urea Nitrogen (BUN) levels decreased as a result of V diet (p<0.05). The fact that use of V, which is a good protein and energy feed, increased ALB level and decreased BUN suggested that a positive protein metabolism was formed in the animals. High-ratio use of V containing anti-nutrient materials like all leguminous grain feeds, was expected to increase ALT and LDH levels; however, it caused decrease in these parameters. This evidenced positive effect of V on liver.
