Effects of raw egg addition to milk at suckling period on growth performance, concentration of serum IgG and some blood parameters in calf

Bu araştırma süt emen buzağıların sütlerine çiğ yumurta ilavesinin besi performansı, serum IgG ve bazı kan parametrelerine etkilerini belirlemek amacıyla yapıldı. Araştırmada bir günlük yaşta 16 adet Holştayn ırkı erkek buzağı kullanıldı. Buzağılar canlı ağırlık ortalamaları birbirine yakın olacak şekilde iki gruba ayrıldı. Kontrol grubundaki buzağılar 59 gün süren araştırma süresince canlı ağırlıklarının % 10’u kadar normal inek sütü ile günde 2 öğün (sabah 08:00, akşam 18:00) halinde beslendi. Deneme grubundaki buzağılar kontrol grubu ile aynı şekilde beslendi, bunun yanında her öğünde sütlerine 1 adet çiğ yumurta ilave edildi. Buzağıların canlı ağırlıkları iki haftalık aralıklarla belirlendi. Serum IgG ve serum parametrelerini belirlemek amacıyla araştırma bitimi olan 59. günde kan örnekleri alındı. Araştırma sonu itibariyle; canlı ağırlık, canlı ağırlık artışı, yem tüketimi ve yemden yararlanma oranı bakımından gruplar arasında istatistiksel bir farklılık görülmedi. Deneme grubunun serum IgG konsantrasyonu kontrol grubundan önemli derecede yüksek bulundu (p<0.01). Serum total kolesterol, trigliserit, HDL, LDL, VLDL ve total protein konsantrasyonları gruplar arasında istatistiksel olarak farklılık göstermedi. Sonuç olarak; buzağı sütüne çiğ yumurta ilavesinin besi performansını, serum lipit metabolizması ürünlerini ve total protein miktarını değiştirmediği, buna karşın immun sistemi güçlendirdiği kanaatine ulaşıldı.The study was conducted to determine raw egg addition to milk at suckling period on growth performance, concentration of serum IgG and some blood parameters in calf. Sixteen, 1 day age male Holstein calves were used in this study. They were divided into two groups according to similar body weight. Calves in the Control group were fed normal cow milk during the 59 day of study period, at the rate of 10 % their body weight as two meal (morning 08:00, night 18:00). Calves in the Trial group were fed in the same way, but at the each meal, 1 liquid egg supplemented their milk. Body weights of the calves were determined biweekly interval. At 59 d of blood samples were collected by jugular vein for measurement of IgG and blood biochemistry parameters. There was no statistical difference on the body weight, weight gain, feed intake and feed conversion at the end of the study between the groups. Serum IgG in the liquid egg supplemented group was higher in the Trial group than those of the Control. There were no statistical differences on the serum total cholesterol, triglyceride, HDL, LDL, VLDL and total protein between the groups. In conclusion; it is concluded that liquid egg supplementation for calf milk did not affect on the growth performance, serum lipid fraction and total protein, while it fortified the immun system

The objective of this study was to determine effects of terebinth fruit oil (TFO) supplementation to diet on growth performance, carcass characteristics, some blood parameters and composition of breast meat fatty acids in Japanese quails. Totally 240 unsexed daily Japanese quail chicks were assigned randomly to three treatment groups. Each group divided into 4 replicates, each containing 20 birds. A group was fed with basal starter diet for 1-21th days and grower diet for 22-42th days (Control). Treatment groups were also fed same diets additionally their ration added by 130 (Group A) or 260 mg/kg TFO (Group B) during the study. At 42 d of study, 20 quails (5 quails from each subgroup) from each group slaughtered for determination of carcass traits, blood parameters and fatty acid composition of breast meat. As a result of this study, final live weight of quails in Group B was found higher than Control and Group A (P<0.05). There were no differences on the average live weight gains of the birds among the groups. Average feed intake in Group A was found lower than Control and Group B on basis of whole study period (P<0.05). Average feed conversion ratio in Group A was found better than Control on basis of whole study period (P<0.05). Carcass weight in Group B was found higher than Group A (P<0.05). There were no differences on carcass yield and breast-, leg-, wing-, heart-, liver- and gizzard ratio to carcass weights of the birds in all groups. Serum total cholesterol, high density lipoprotein, aspartate amino transferase, alkaline phosphatase, total protein, albumin and globulin did not differ among the groups. There were no differences on composition of breast meat fatty acid profiles. In conclusion, due to supplementation of 260 mg/kg TFO enhanced live weight and carcas

Effects of L-carnitine administration on growth performance, carcass traits, blood serum parameters and abdominal fatty acid composition of ducks

Effects of L-carnitine administration via drinking water on growth performance, carcass traits, blood serum parameters and abdominal fatty acid composition of ducks was examined. One hundred day-old Turkish native duck chicks were divided into two groups, each with five replicates and given the same diets with 0 and 200 mg/l carnitine chlorhydrate via drinking water. The study lasted 8 weeks, with the first 4 weeks as a starter and the last 4 weeks as grower period. At the end of the study five ducks were randomly selected from each subgroup for slaughter. Growth performance parameters of ducks were not affected significantly by L-carnitine administration. Live weight, daily weight gain, cumulative feed consumption and average feed conversion efficiency were found to be 1490 and 1621 g, 26.0 and 28.1 g, 5386 and 5662 g, 3.75 and 3.54 kg/kg in the control and in the carnitine groups respectively. L-carnitine administration did not effect carcass traits and serum cholesterol, total lipid, triglyceride and glucose levels. Total saturated fatty acid content of abdominal fat significantly decreased, mono- and polyunsaturated fatty acid content were not affected by L-carnitine administration. In conclusion, L-carnitine administration by drinking water did not affect growth performance, carcass traits and blood parameters in ducks

Two hundred a-day-old chicks were divided into two groups, allocated to 5 replicates, each consisting of 20 chicks. At the end of the 6 weeks experimental period, results indicated that administration Of L-Carnitine did not significantly influence growth performance and carcass traits in quails. Administration Of L-Carnitine did not significantly affect serum cholesterol, total lipid, triglycerid, total protein and albumin levels (P > 0.05) but increased the glucose level (P < 0.05)

Effects of feeding by hay, grass silage and corn silage on growth performance, rumen fluid and blood serum parameters in beef cattle

The study was conducted to determine the use of hay, grass silage, corn silage and grass silage+corn silage as roughage sources on growth performance, some rumen and blood serum parameters in beef cattle. A total of 24 Simmental beef cattle (12 male, 12 female), 9 or 10 months age, which were initially 142.4 kg live weight, were used in this study. The animals were divided into four treatment groups each consisting of 6 cattle (3 male, 3 female). All animals in the groups were fed with 2888 g for 0-21 d, 3813 g for 22-42 d and 5177 g for 43-63 d concentrated feed. In addition to the concentrated feed, one of the following roughage source hay, grass silage, corn silage or grass silage+corn silage (50:50) were given ad libitum to animals in each group. Animals were fed by group basis. At the 63 d of the study, rumen fluid and blood serum samples were taken from the animals. Final live weights of the animals did not affect. Average daily weight gains of the cattle in the overall study were no statistical differences among the groups. The roughage sources did not affect rumen fluid pH, NH3 N, acetic-, propionic- and butyric acid concentrations of beef cattle. The roughage sources did not also affect serum glucose, total protein and albumin concentration of animals. Consequently, it is concluded that mentioned roughage sources could be preferred as alone or grass silage+corn silage combination in feeding of beef cattle after economic analyses of these feedstuffs
