SUMMARY: The aim of the study was to determine various morphological characteristics from birth to the age of 150th day of Boer x Hair goat F1 crossbred (BH) kids and pure Hair goat (HG) kids raised in semi-intensive conditions and reveal factors such as the effects of genotype, dam age, dam’s live weight, year, birth type and sex on this parameter. This study was applied between the years 2011-2012 in Çatak in the Van region and between the years 2013-2014 at the Yuzuncu Yil University Research and Practice Farm.

When all of the data was considered, it was concluded that the BH kids are much better than the HG kids for both morphological and zoometric values.

RESUMEN: El objetivo del estudio fue determinar varias características morfológicas desde el nacimiento hasta la edad de 150 días en caprinos Boer x Hair goat F1 crossbred (BH) y Cabra pura (HG) criados en condiciones semi-intensivas y revelar factores tales como los efectos del genotipo, la edad, el peso vivo de la el tipo de nacimiento y el sexo entre otros. Este estudio fue realizado entre los años 2011-2012 en Çatak, región de Van y entre los años 2013-2014 en la Granja de Investigación y Práctica de la Universidad Yuzuncu Yil. Se estudiaron diversas medidas corporales: Altura del talón, altura de la espalda, altura de la grupa, altura del sacro, longitud del cuerpo, longitud del pecho, profundidad del tórax, circunferencia del pecho, circunferencia de la pierna, circunferencia del hueso del cañón, ancho del pecho, ancho de la grupa delantera y anchura media de la grupa, así se determinaron 29.8, 28.4, 28.7, 26.2, 28.7, 17.0, 13.3, 30.4, 26.9, 5.2, 5.9, 6.0 y 8.7 cm al nacer, respectivamente; 43.8, 43.8, 44.6, 40.6, 43.6, 22.2, 19.3, 51.7, 41.4, 6.6, 9.2, 9.3 y 11.3 cm en el 60º día, respectivamente; 56.1, 53.4, 54.4, 47.5, 53.3, 27.3, 24.1, 61.4, 49.6, 7.3, 10.6, 11.1 y 13.2 cm en 150 días, respectivamente para niños BH; 27.3, 25.9, 29.3, 25.3, 27.1, 15.9, 12.3, 29.0, 21.3, 5.1, 5.0, 5.6 y 7.4 cm al nacimiento, respectivamente; 40,4, 40,1, 42,9, 37,6, 40,5, 22,3, 18,4, 48,1, 36,4, 6,0,7,9, 9,1 y 10,8 cm en el 60º día, respectivamente; 50.3, 49.2, 51.0, 45.7, 50.4, 27.5, 22.9, 57.3, 43.4, 6.5, 9.5, 10.7 y 11.9 cm a los 150 días, respectivamente, para cabritos HG. Cuando se consideraron todos los datos, se concluyó que los cabritos BH son mucho mejores que los cabritos HG para los valores morfológicos y zoométricos.

ABSTRACT This study aimed to evaluate the effects of different levels of synbiotic (Syn) on the growth performance, carcass traits, and serum parameters of Japanese quails. A total of 1,500 (750 male and 750 female) Japanese quails were assigned to five treatments, including the control (basal diet) and basal diets with the addition of 0.1, 0.2, 0.3, and 0.4% Syn according to a completely randomized design. Each treatment in the male and female experiment groups consisted of five replicates, with 30 chicks for each replicate. The addition of Syn had no effect on body weight (BW), while the BW of female quails was higher than that of male quails at day 42. The addition of Syn reduced feed intake (FI) and improved the feed conversion ratio (FCR) (P<0.000). The daily body weight gain and FI were significantly higher in female than in male quails and Syn also improved the FCR in the overall experiment. The effect of the addition of Syn on carcass parameters (except for abdominal fat) was not determined. The addition of Syn decreased abdominal fat weight and percentage when compared with the control group. Male quails were found to have higher carcass yield, wing, neck, and other percentages than female quails. However, female quails were found to have higher breast, breast skin, abdominal fat, and visceral organ percentages. The addition of 0.1% Syn to quail ration reduced serum aspartate aminotransferase, high-density lipoprotein (HDL), total protien (TP), and albumin (ALB) levels at day 42 of the trial. The addition of Syn decreased the serum total cholesterol level. Gender was found to have an effect in that female quails were found to have higher total cholesterol, HDL, TP, and ALB levels than male quails. In both genders, the addition of Syn improved the BWG, FC, and FCR in the overall experiment, reduced abdominal fat, decreased the total cholesterol levels, improved the HDL levels, and increased the TP and ALB levels at day 42. The addition of 0.3 and/or 0.4% synbiotic has a positive effect on quails by improving performance and enhancing some serum lipids and protein parameters.
