Biometrical Study

  The experiment was conducted to characterize different breeds of pigeon phenotypically and to study their body biometry, which are available in the northernBangladesh. During this study 30 farms were selected which have >20 pair of pigeons in the three study area namely Rajshahi, Natore and Pabna districts ofBangladesh. There about 15 breeds have been selected for the observation of  phenotypic characteristics such as color of bill, eye, eyelid, skin, shank, toe, egg, head feather, neck feather, body feather, down feather, wing feather, tail feather and shape of bill, body and egg. The biometrical data were collected from the measurement of length of bill, head, body, shank, middle toe, wingspan and mature body weight. In this study the highest mean bill length was found 2.83±0.05cm in Strasser and lowest mean head length 5.00±0.00cm in Kormona, Nun and Jacobin. The highest mean body length was found 41.60±0.38cm in Strasser and lowest mean body length 30.00±0.43cm in Owl.  The highest mean wingspan was found 81.00±0.51cm in Jacobin and lowest mean wingspan 60.45±0.76cm in kormona. The heighest mean shank length was found 3.40±0.13cm in Homer and lowest mean shank length 2.50±0.00cm in Giribug, Kormona, Nun, Satinette and Suachandan. The heighest mean middle toe length was found 4.40±0.05cm in pouter and lowest mean middle toe length 3.00±0.00cm in kormona. The heighest mean mature body weight was found 748.20±8.96gm in Strasser and lowest mean mature body weight 265.10±7.03gm in Giribug. Phenotypic correlation among bill length, head length, body length, wing span, shank length, middle toe length and mature body weight of these breeds of pigeon ranged from 0.233 to 0.789. The experiment’s result may contribute to breed up gradation, helps to formulate the conservation and improvement strategies for the breed as genetic resource.

Biodiversitas 20: 1264-1273.  The objective of this study was to evaluate phenotypic diversity of White tail-yellow chickens in Mueang District, Phitsanulok, Thailand. A total of 200 male chickens from the purposive samples were collected, and then analyzed by using descriptive statistics, correlation and least squares mean for subclasses of each factor. The results showed that the phenotypic of White tail-yellow Chickens had the highest white-yellow beak (60.29%), hin comb (65.50%), golden-yellow neck plumage (95.69%), back plumage (96.17%) and wing plumage (67.94%), white-black long curving tails (70.11%), black back tails (71.14%) and white-yellow shank (59.81%) for qualitative traits. The quantitative traits such as body weight, body height, body length, body width, wing length, shank length, and toes length were 2.78±0.58 kg, 61.95±3.77 cm, 24.93±1.66 cm, 16.62±1.91 cm, 41.85±2.52 cm, 12.72±0.77 cm, and 8.39±0.66 cm, respectively. The highest positive correlation was recorded between neck plumage and back plumage (r=0.70; p<0.01). Moreover, body weight was the highest correlation with wing length (0.58; p<0.01) whereas body length was the highest positive correlation with wing plumage (0.21; p<0.01). However, beak and comb had no significant effect on all traits (p>0.05) except for neck, back and wing plumage, long curving tail, back tail and shank color (p<0.05).

The study aimed at explaining objectively the relationship between morphologic traits of two breeds of pigs (Large-white and Duroc) using principal component analysis to determine the body size of grower pigs of two different breeds with a view of identifying components that best define body conformation. Body weight and five biometric variables namely head length, body length, body girth, ham length and ear length. The descriptive statistics showed that the mean body weight of Large-white was 13.14kg while the body measurements were 24.61cm, 71.35cm, 65.12cm, 43.13cm and 21.94cm for head length, body length, body girth, ham length and ear length respectively at 5 – 24 weeks of age. The mean body weight of Duroc was 12.87kg while the body measurements were 23.70cm, 57.93cm, 47.93cm, 22.90cm, 19.26cm for head length, body length, body girth, ham length and ear length respectively. The coefficient of correlation ranges from 0.08-0.424 and 0.01-0.402 for Large-white and Duroc respectively. The association between and were the highest for Duroc, body length r=0.402 and Large-white, body girth 0.424. Two components were identified for Large-white while those of Duroc were three components. The ratios of variance were 53.55 and 71.07% for Large-white and Duroc, respectively. The first factor in each case accounted for the biggest percentage of the total variation, and was designated the general size, the other factors (indices of body shape) offer forms of variation independent of the general size. The principal component based regression models which were chosen for selecting animals for optimal balance accounted for 58 and 76% of the variation in the body weight for Large-white and Duroc respectively. The study concluded that the use of principal component analysis techniques tends to explore the interdependence in the original five parameters measured: head length, body length, body girth, ham length and ear length of Large-white and Duroc     L'étude explique objectivement la relation entre les traits morphologiques de deux races de porcs (gros blanc et de Duroc) à l'aide d'une analyse de composants principaux afin de déterminer la taille du corps des porcs de producteurs de deux races différentes en vue d'identifier les composants qui définissent le mieux la conformation corporelle. Poids corporel et cinq variables biométriques, nommément longueur de la tête, longueur du corps, circonférence du corps, longueur du jambon et longueur de l'oreille. Les statistiques descriptives ont montré que le poids corporel moyen de gros blanc était de 13,14 kg tandis que les mesures du corps étaient de 24,61 cm, 71,35 cm, 65,12 cm, 43,13 cm et 21,94 cm pour la longueur de la tête, la longueur du corps, la circonférence du corps, la longueur du jambon et la longueur de l'oreille respectivement à 5 - 24 semaines. Le poids corporel moyen de Duroc était de 12,87 kg tandis que les mesures du corps étaient de 23,70 cm, 57,93 cm, 47,93 cm, 22,90 cm, 19,26 cm pour la longueur de la tête, la longueur du corps, la circonférence du corps, la longueur du jambon et la longueur de l'oreille respectivement. Le coefficient de corrélation varie de 0,08 à 0,424 et de 0,01 à 0,402 pour les gros blancs et Duroc respectivement. L'association entre et étaient les plus élevées pour Duroc, la longueur du corps R = 0,402 et de gros blancs, la circonférence du corps 0,424. Deux composants ont été identifiés pour les gros blancs tandis que ceux de Duroc étaient trois composants. Les ratios de variance étaient respectivement de 53,55 et 71,07% pour les gros blancs et Duroc. Le premier facteur de chaque cas représentait le plus gros pourcentage de la variation totale et a été désigné la taille générale, les autres facteurs (indices de la forme du corps) offrent des formes de variation indépendantes de la taille générale. Les principaux modèles de régression basés sur les composants choisis pour sélectionner des animaux pour un solde optimal représentaient 58 et 76% de la variation du poids corporel pour les grands blancs et Duroc respectivement. L'étude a conclu que l'utilisation de techniques d'analyse des composants principaux a tendance à explorer l'interdépendance dans les cinq paramètres d'origines mesurées: longueur de la tête, longueur du corps, circonférence corporelle, longueur du jambon et longueur de l'oreille de grosse blanc et de Duroc

ABSTRACTThe body dimensions and live weight of 126 Mule (Bluefaced Leicester × Scottish Blackface) and Scottish Blackface ewes were measured during the 1986/87 housing season. Body dimensions included: head and neck length, body length, diagonal body length, height to withers, height to rump, girth at widest point, heart girth, width at widest point and width at shoulders. It was found that most body dimensions varied greatly with body weight. However, some body dimensions such as head length were found to be independent of weight within the weight range studied. Prediction equations are presented for each body dimensions for unshorn sheep.These predictions can be used as a basis for the design of sheep housing, for example, trough space allowances, design of feeders or as a biological basis for space allowance.

Data on body weight and linear body measurements collected from 101 America StandardChinchilla rabbits comprised of 62 females and 39 males at eight weeks were used todetermine the effect of sex and phenotypic correlations among the growth traits. Theestimates were statistically (p<0.05) higher in the female compared with male in virtually all the traits considered except in the fore arm length. The values for body weight, body length, ear length, tail length, fore arm length, heart girth and abdominal circumference for females were 1.19 kg, 31.97 cm, 10.67 cm, 9.89 cm, 15.61 cm, 21.61 cm and 23.75 cm, respectively while the corresponding values for males were 0.88 kg, 28.00 cm, 10.44 cm, 8.95 cm, 14.74 cm, 19.62 cm and 21.67 cm. The correlation between body weight and the linear body measurements was positively significant (p<0.05 and p<0.001) and ranged between 0.301 and 0.951 in males while in females positive and significant correlations were found between body weight and body length (0.831), tail length (0.184), heart girth (0.788) and abdominal circumference (0.719). The correlations among the linear body measurements in the males ranged between 0.108 and 0.951 while in females it ranged between -0.235 and 0.681. The positive relationships between body weight and linear body measurements can be used as basis for body weight selection in both male and female rabbits

Sheep Breeds

Identify the genetic resources of the sheep and characterize these breeds accurately are very important to enhance the good performances of sheep and expand the knowledge of the differences among those breeds. Body measurements therefore, are perfect indicators to make definition for each breed. The present study is part of a wide one to definite of phenotypic characteristics in local breeds of sheep in Qassim region, Kingdom of Saudi Arabia. The data were collected from three breeds in Qassim region, Noemi, Najdi and Hari. Najdi is the biggest breed of the sheep breeds in Saudi Arabia and it is the main breed in Najd region. Noemi is taking the second size breed of the sheep breeds in Saudi Arabia. Hari is the smallest breed of sheep breeds in Saudi Arabia, it is the main breed in Hejaz and Assir regions, which belong to the sheep with coarse hair, and thick tail strain. Eight body measurements traits were studied, Wither heights (WH), Rum heights (RH), Body length (BL), Head length (HL), Heart girth (HG), Muzzle diameter (MD), Cannon circumference (CC) and Cannon length (CL).&nbsp; The correlations coefficients among all studied traits were moderate to high and highly significant. The highest correlation coefficient was found between RH and WH traits (0.872), and the lowest one was found between CC and HG traits (0.214). The correlations coefficients between relative traits can help us to understand the similarity among studied traits and can be used in the future in selection program.

Nine neonatal and juvenile snakes, four vipers and five nonvipers, were fed rodent meals varying in size, expressed as percent of snake body weight. The number of mandibular protractions and the time to complete swallowing were recorded, with both measures increasing linearly as a function of meal size. These young snakes routinely swallowed meals that were 50% of body weight, and ranged up to 80%, far higher than meals reported by previous workers studying adult vipers (36.4%) and nonvipers (18.4%). Furthermore, the slopes of regressions relating mandibular protractions to meal size in all of our snakes were lower than comparable slopes for adult vipers or nonvipers. We hypothesized that the relatively long and wide skulls of young snakes (i.e., as proportion of body length) were responsible for these ingestive accomplishments, with negative allometric growth being responsible for performance changes during ontogeny.

Abstract Raramuri Criollo (RC) are one of 33 known biotypes of heritage Criollo cattle that exist throughout the Americas today. They have been raised by the Tarahumara peoples of the Copper Canyon in Chihuahua, Mexico, for over 400 years and exhibit remarkable rusticity and adaptation to harsh grazing environments. To date, no quantitative phenotypic description of this biotype exists. Our objective was to characterize RC cattle via 26 phenotype traits to provide a preliminary biotype standard. Twenty-eight multiparous RC cows, 4 primiparous heifers, and 4 bulls were selected from a purebred herd of approximately 200 animals at the USDA-ARS Jornada Experimental Range. These 36 animals were selected by a Criollo cattle expert based on body conformation correctness. SAS 9.4 was used to determine means, SEs or frequency of measured traits. Multiparous pregnant and cycling cows averaged 366.8 ± 9.8 kg live body weight, 121.8 ± 0.9 cm withers height, horn widths of 60.3 ± 1.6 cm, horn diameters of 5.7 ± 0.1 cm, chest girths of 183.6 ± 12.0 cm, hip widths of 44.5 ± 0.5 cm, flank girths of 52.2 ± 0.9 cm, body length of 90.0 ± 1.7 cm, neck lengths of 52.0 ± 0.9 cm, and tail lengths of 83.3 ± 1.4 cm. Bulls consistently averaged higher values for all traits and weighed 618.2 ± 9.8 kg with scrotal circumferences of 36.8 ± 0.7 cm. RC cattle exhibited mostly convex nose bridges (89%), open-back horns (49%), black muzzles, hooves, and eyes (62, 69, and 81%, respectively), small ears (78%), oblique eyes (70%), high-set tail heads (86%), short hooves (95%), and short hair (78%). Our preliminary characterization of RC phenotypes will be useful in selecting RC individuals for genotypic evaluation to eventually maintain a distinct purebred registry of this Criollo biotype.
