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.

Majority of the Kargil sheep populations are indigenous. Very scanty information is available for morphological characterization of Purky sheep population. Therefore, the present study was undertaken with the objectives to study the morpho-metric characteristics and body measurements for phenotypic characterization of the local sheep. A stratified random sample survey was conducted on various parameters (horn size, tail size, chest girth, punch girth, body length, height at wither and body weight) in seven different age groups. Data were collected randomly from 510 sheep of either sex. The local sheep population of Kargil which was selected for the present investigation is named as ‘Purky’ by the name of the community that reared this breed. In Purky sheep white body colour was predominant in both the sexes. The sheep breed was of low to medium body weight. The chest girth, punch girth, height at withers of Purky sheep showed it to be medium sized. Sex had significant effect (P is less than 0.05) on height at wither only. For males the least squares means were higher for all the traits of all age groups baring few exceptions. The phenotypic correlations of age groups with different morpho-metric traits were very high. The phenotypic correlations of body weight with other body measurements like tail size, chest girth, paunch girth, body length and height at wither were very high. Further studies should be carried out to fully exploit their genetic potential and to register the breed and in-situ conservation of this population.

Abstract: The objective of this work was to phenotypically characterize creole goats of the Moxotó, Azul, Canindé, Repartida, Marota, and Graúna breeds, comparing them with the Boer, Anglo Nubian, and Alpine exotic breeds, to identify the genetic groups of greater potential for carcass quality and resistance to infection caused by worm. Data on morphometric measurements were obtained for the count of worm eggs in grams of feces (WEGF), Famacha score, carcass measurements, and body weight from 308 animals, in a farm in the state of Piauí, Brazil. Repartida goats showed the highest average for wither height (61.55 cm) and rump height (62.16 cm), and Moxotó goats had the greatest ear length (13.45 cm). The Moxotó breed showed the highest means for carcass and body weight. The lowest average for body weight was observed in Azul goats (24.35 kg), and the lowest WEGF was detected in Repartida goats (200 eggs per gram of feces). The average Famacha score was 2.77. Average linkage was the method that best summarized the information on the morphometric and carcass data. The use of morphometric and carcass measurements provides satisfactory results in the phenotypic characterization of the animals. The Brazilian creole goats, which are considered resistant to worm infection and show high-quality carcass traits, may be indicated for conservation and genetic breeding programs.

SummaryThe Moroccan goat livestock is characterized by the existence of different phenotypes distributed among diverse geographic locations. The objective of this study was to analyse the morphometric traits that differentiate the Draa breed from the other local populations raised in areas close to its cradle zone. Eight morphometric measurements were taken on 287 goats in South-eastern and Southern Morocco. The variance analysis, fitting a model that included the random effect of animal and the fixed effects of population, gender and age of animal, was used. Mahalanobis distances were calculated between identified populations and an Unweighted Pairs Group Method Analysis tree was built. Draa goats had the highest height at withers (61.5 cm), heart girth (74.4 cm), body length (64.6 cm) and live body weight (27.2 kg). These morphometric traits varied significantly among populations as well as the age and the gender of animal. The most discriminating traits between the identified populations were the body length, the heart girth, the hair length, the horn length, the ear length and the live body weight. Draa animals had the largest genetic distances from the other populations and appeared more distinguished from them. This differentiation can contribute in defining the phenotypic standard of the breed and in orienting its genetic improvement programs in the future.

Background: Kachchhi-Sindhi horses are famous for their ‘Rewal chal’ (a unique style of running). These horses dominantly exist in the western-northern border of India adjoining Pakistan. The breeding tract of these horses is Surat, Navsari, Kachchh district of Gujarat and Jaisalmer-Barmer districts of Rajasthan in India. Most familiar colors in the Kachchhi-Sindhi horses are bay and chestnut. Roman nose, ears curved at tips but not touching each other, short back, short pastern length, broader hoof for better grip and docile temperament are major characteristics of these horses.Methods: The present study is an effort to phenotypically characterize Kachchhi-Sindhi horse breed based on their different biometric indices for selection and conservation of stallions and mares for breeding purposes by private breeders. Fourteen biometric indices were recorded for phenotypic characterization of each breed viz., height at wither (HW), body length (BL), heart girth (HG), neck length (NL), face length (FL), face width (FW), pole, ear length (EL), ear width (EW), foreleg length (FLL), canon, pastern, hoof length (HoL) and hoof width (HoW). On average, these horses stand 148 cm height, have a body length of ~140 cm, a heart girth of ~165 cm, an ear length of ~15 cm and a face length of ~61 cm.Result: Horse keepers sustain horses in intensive as well as an extensive system of rearing. It has also been ascertained from various sources that horse number is declining rapidly, however, breed population statistics are not available. There is, therefore, an urgent need to conserve this breed. Proper managemental practices and conservation efforts will pave the way for the multiplication of this valuable equine genetic resource of India.

SummaryHassawi cattle breed is a mix of Bos indicus and Bos taurus. The cattle are raised in the Eastern province of the country by farming families in mixed farming system. The breed numbers are declining very fast, from 10 449 head in 1986 to an estimated maximum of 4 500 head at present.The decrease is mainly due to replacement by exotic breeds, the indiscriminate crossing with these exotics, particularly in view of the scarcity of the Hassawi bulls for mating. Animals are small in size, mature body weight 210-270 kg for bulls and 150-200 kg for cows, quite uniform in colour (light red) and body conformation have conspicuously reduced dewlap and umbilical folds and relatively large hump. Animals are heat tolerant, sustain high feed intake under ambient temperature, resistant to many diseases prevailing in the region and cows have good mothering ability. Productivity of the breed in terms of meat and milk is low when compared to that of exotics in high input production environments, but reproduction performance excels that of temperate breeds and zebu cattle.Efforts should be made to stop the decline in the breed numbers and to conserve the breed as an asset for production under harsh environment.

SummaryThe study examines phenotypic characterization of Central Highland and Woyto-Guji goat breeds at Meta Robi and Konso districts of Ethiopia. Purposive and random sampling techniques were employed to select sample villages and respondent. For administration of semi-structured questionnaire and phenotypic characterization, a total of 240 households and 601 adult animals, respectively, were selected. The average goat flock size (31.25 ± 22.46) owned per household of Konso was significantly (P< 0.01) higher than Meta Robi (12.73 ± 8). In Konso, natural pasture was the most frequently mentioned feed source during wet season, while hay was the most important feed source during dry season. On the other hand, in Meta Robi, natural pasture was the most frequently mentioned feed source during wet and dry seasons. Coat colour type, horn shape, ear orientation, wattle and beard were found to differ highly significantly (P< 0.001) among the two goat breeds. Goat breed had a significant effect (P< 0.001) on body weight and other body measurements except pelvic width (P> 0.05). The least-square means of body weight, body length, height at wither, chest girth, chest width, ramp length, horn length, ear length and pelvic width of Central Highland female goats were 29.5 ± 0.2 kg, 62.2 ± 0.2 cm, 67.5 ± 0.2 cm, 72.9 ± 0.2 cm, 13.4 ± 0.1 cm, 19.7 ± 0.1 cm, 12.8 ± 0.2 cm, 14.6 ± 0.1 cm and 13.5 ± 0.1 cm, respectively. The corresponding values for Woyto-Guji female goats were 24.8 ± 0.3 kg, 57.4 ± 0.2 cm, 61.9 ± 0.2 cm, 68.3 ± 0.2 cm, 12.1 ± 0.1 cm, 17.3 ± 0.1 cm, 10 ± 0.2 cm, 13 ± 0.1 cm and 13.4 ± 0.1 cm, respectively. The observed variations in production system and morphological traits among the sample populations coupled with their adaptive traits would indeed justify the need for designing breed improvement programme for both breeds.

The present investigation was conducted in the herd of pure bred Sahiwal cows maintained at Bull Mother Experimental Farm (BMEF) and Government Cattle Breeding Farm (CBF), Anjora, Durg (Chhattisgarh). A total of 193 adult female Sahiwal cattle over three years of age were used in the experiment. The animals were grouped into seven age groups, i.e. 3-4, 4-5, 5-6, 6-7,7-8,>8 years old, and overall. Body weight was found to be significantly (P less than 0.01) and positively correlated with height at withers (r= 0.58 to 0.73), body length (r= 0.56 to 0.76) and heart girth (r= 0.57 to 0.80) in these groups. The relatively high value of coefficient of correlation between live body weight and heart girth assumed to be more significant indicator of live body weight in Sahiwal cattle.

Characterization of Black Bengal bucks and does was performed in this study. A total of 50 goats of different aged were studied. The experiment was performed in Black Bengal bucks and does at 1<sup>st</sup> day and at 3, 6, 9 and 12 months of age for measuring different parameters such as body length, heart girth, wither height, hip height, fore and hind leg length, head length and width, head length and width, ear length and ear breath, scrotal length and scrotal circumference. In a single parameter as body weight of Black Bengal bucks and does at 1<sup>st</sup> day and at 3, 6, 9 and 12 months of age were found to be 1.08±0.06, 5.22±0.33, 8.95±0.34, 12.05±0.47 and 14.20±0.20; and 1.01±0.23, 3.93±0.19, 7.41±0.27, 9.53±0.38 and 12.40±0.41 kg respectively. Whereas all the finding where gradually increased for all parameters according to their specific age periods. Body weight has a strong positive relationship with heart girth, body length, height at wither, scrotal length and scrotal circumference in Black Bengal goat. All the parameters studied found comparatively higher in bucks than does.
