The study was undertaken to characterize of Black Bengal Goat (BBG) under farming condition. Data on the different parameters were collected during July 2006 to June 2013 at BLRI goat research farm. A total of 299 animals of different ages from birth to 36 months of both sexes were included. All type of measurements were taken when goats standing freely. All measurements were taken in metric unit. Data were analyzed by SPSS version 17.0 statistical computer program. In BLRI goat herd, four different types of coat color were observed in BBG i.e. Black, Black and white, Black and brown and completely white. Body length is higher in males than that of females for all generation and age group. Male goats had higher heart girth than that of female goats irrespective of age and generations. Average adult (>24 months age) body weight of male and female goats as 29.9±1.76 and 23.6±0.81 kg, respectively. Wither height was higher in adult males than females for same age. Left and right horn length in both sexes ranged from 3.6 to 13.2 cm. Female goats had higher ear length than male goats. Tail length of Black Bengal goats ranged from 8.0±0.52 to 11.1±0.43 cm and tail breadth ranged from 2.1±0.10 to 3.6±0.43 cm for different age and sex group. Average male foreleg length in >24 months of age possessed higher than that of female. Average udder length and breadth of BBGs were 7.5±0.24, 11.7±0.44 and 14.3±0.46 and 5.9±0.16, 7.4±0.28 and 7.8±0.23 cm, respectively for age groups 6-12, 12-24 and >24 months of age. The average testis length and breadth in adult males were 9.1±0.18, 7.5±0.48 and 9.8±0.49 and 6.8±0.13, 5.2±0.27 and 6.3±0.32, cm respectively for 6-12, 12-24 and >24 months of ages groups.Asian J.

Qualitative Characteristics

Eighteen quantitative measurements and fourteen qualitative characteristics taken from 306 adult sheep (57 rams and 249 ewes) were used to characterize sheep populations of district, Ethiopia. Most traits showed significant variation by zone, sex and age groups with higher values generally recorded for rams as compared to ewes. Middle age group animals displayed highest values for several traits, reflecting the optimal production age. zone affected ewes more than rams. The highland sheep height at withers, widest shoulder points and longest hair, indicative of adaptation to their environment. Qualitative characteristics of the studied sheep populations such as tail shape, plain coat color pattern, skin, hairy fiber and the absence of horn, toggle, ruff and beard suggest that they constitute a previously sheep breed. Tan coat color differentiated high and midland sheep from lowland sheep where white and brown colors were dominant. Canon bone length, height at withers and tail length were the three most important variables used in discriminating the sheep populations. On average 66% of the animals could be classified into their respective zone. Our data suggest that highland sheep populations are distantly related to lowland sheep, while midland sheep are more closely related to lowland sheep. It can be concluded that breeding programs specific to each zone need to be designed for sustainable utilization and conservation of the studied sheep populations. Furthermore, molecular based studies might allow further characterization of Ethiopian sheep breeds.

Morphometric Characterization

Donkeys (Equus asinus) is a domestic livestock popular in helping farming activities and providing food for some societies. Population of donkeys were drastically decreasing due to the overexploitation for its hides and industrialization. Little is known regarding the morphometric measurements of this species which provide a useful information for selective breeding and genetic conservation. One hundred and forty-four male donkeys from D/Kudu Kano state where enrolled in this study for morphometric characterisation. Seven morphological parameters were analysed in association with age and coat colour of donkeys observed. Descriptive statistical analysis, analysis of variance (ANOVA) as well as correlation coefficient among parameters were evaluated. Result revealed that donkeys in the studied area were categorised into 7 different coat colour with light grey (30.6%) being the dominant colour. High Frequency distribution of donkeys between the ages of 5-7 years (41%) were recorded. Also, both age and coat colour showed a significant (P <0.01) difference on face length, ear length, chest circumference and body length. Significant and positive correlation (r = 0.43–0.91) is observed in all morphological traits except relationship for tail length which is negatively correlated. In conclusion, the morphological features analysed in this study can be regarded as a preliminary for further studies on the Kano donkey breed.

Total 535young Red Kandhari cattle were selected morphometric measurements were recorded by using measuring tape while physical characteristic were recorded visually.The overall LSQ means at 0-3 months of Red Kandhari for chest girth, abdominal girth, body length, height at wither, height at elbow, height at hip bone, height at pin bone, length of ear, width of ear, length of face, width of fore head, length of neck, width between hook bone, width between pin bone, tail length and body weight were 70.56 ± 0.66, 72.27 ± 0.78, 64.06 ± 0.69, 69.00 ± 0.63, 42.93 ± 0.37, 69.44 ± 0.66, 65.13 ± 0.63, 13.66 ± 0.21, 7.54 ± 0.07, 23.21 ± 0.32, 11.25 ± 0.18, 25.02 ± 0.26 , 15.71 ± 0.16 , 9.08 ± 0.15, 41.66 ± 0.44 cm and 30.06 ± 0.83 kg and at 4-12 months of age were 116.21 ± 0.73, 122.86 ± 0.77, 99.89 ± 0.51, 102.32 ± 0.43, 60.49 ± 0.59, 103.71 ± 0.44, 97.51 ± 0.38, 18.38 ± 0.16, 10.28 ± 0.24, 35.55 ± 0.24, 18.11 ± 0.08, 38.50 ± 0.13, 26.43 ± 0.22, 14.83 ± 0.18, 60.90 ± 0.39 cm and 127.93 ± 2.42 kg, respectively. Majority of the Red Kandhari cattle have Brick Red coat color followed by Dark Red. The sex showed highly significant (P Lass Than 0.01) to significant (p Lass Than 0.05) effect on most of the traits for both the age group whereas district doesn’t play any major role on these traits.The significant to highly significant effect of sex on some of body measurements and non-significant effect of district in all traits may lead to the concrete conclusion that these factors play a major role in exhibiting the specific body measurements only in Red Kandhari cattle at 4-12 and 0-3 months of age.

Identification And Characterization

In this study, we used high-throughput technology to provide the first transcriptome dataset for differentially expressed miRNA in mixed pools of dermis tissue from black- and white-coated yak to research the possible molecular mechanisms of yak coat pigmentation. In this study, 92,636,002 and 95,917,842 clear reads were generated through Illumina paired-end sequencing. A total of 78 differentially expressed miRNAs (DEMs) were identified, including 59 upregulated and 19 downregulated miRNAs in the mixed pools of white-coated yak compared with the mixed pools of black-coated yak. In addition, 3634 genes were predicted as putative targets of DEMs. These DEGs related to 59 GO categories and were enriched in 216 Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways, including melanogenesis and the Wnt signaling pathway. The results of the current study indicated that the coat color of the yak involved the transcriptional regulation process of miRNAs. These results provide helpful data to understand the molecular mechanisms of yak coat pigmentation.

Morphometric Characterization

The morphological and morphometric characterization of spermatozoa has been used as a taxonomic and phylogenetic tool for different species of mammals. We evaluated and compared the sperm morphometry of five neotropical primate species: Alouatta caraya, Ateles belzebuth and Ateles chamek of family Atelidae; and Cebus cay (=Sapajus cay) and Cebus nigritus (=Sapajus nigritus) of family Cebidae. After the collection of semen samples, the following parameters were measured on 100 spermatozoa from each specimen: Head Length, Head Width, Acrosome Length, Midpiece Length, Midpiece Width and Tail Length. Considering the available literature on sperm morphometry, we gathered data of 75 individuals, from 20 species, 8 genera and 2 families. These data were superimposed on a phylogeny to infer the possible direction of evolutionary changes. Narrower and shorter spermatozoa seem to be the ancestral form for Cebidae, with a trend toward wider and larger heads in derived groups. The spermatozoa of Atelidae may show an increase in total length and midpiece length. Sperm heads would have become narrower in the more derived groups of Ateles. Sperm length may increase in the more derived species in both families. Our results are discussed in the context of sperm competition and sexual selection.

The present study was conducted at the Artificial Insemination Center, Bangladesh Agricultural University, Mymensingh to record the Black Bengal bucks morphology and to relate body weight with different body measurements. A total of 22 Black Bengal bucks of different ages were taken and were divided into six age groups (0, 3, 6, 9, 12 and 15 months). The body weight of Black Bengal bucks at 0, 3, 6, 9, 12 and 15 months of age were 1.21 ± 0.12, 4.26 ± 0.25, 7.68 ± 0.31, 12.76 ± 0.42, 16.56 ± 0.57 and 21.82 ± 0.70 kg respectively. Age had a significant effect (P<0.05) on heart girth, body length and height at wither (P<0.05) except the measurement of height at wither at 0 and 3 months. The measurement of fore and hind leg length, head length and width, ear length and breadth and also tail length differed significantly (P<0.05) between the age groups. The average scrotal circumferences (SC) were recorded as 4.85 ± 0.22, 10.35 ± 0.39, 15.42 ± 0.34, 18.05 ± 0.24, 19.72 ± 0.33 and 20.83 ± 0.41 cm at 0, 3, 6, 9, 12 and 15 months of age, respectively and differed significantly (P<0.05) with the advancement of age. Animals of the same age group supposed to be similar in conformation. Body weight was highly correlated (P<0.01) with heart girth (0.94), body length (0.95) and height at wither (0.96).

Morphometric Characterization

Morphometric characterization of Katjang goat in Malaysia is important for conservation and for further genetic improvement. With this idea in view the present study was carried out to characterize the morphometry and to estimate the relationship among the important morphometric traits of indigenous Katjang goat. The study was conducted at the Faculty of Sustainable Agriculture (FSA), surrounding area of FSA Sandakan, Sabah and Batu Pahat, Johor in Malaysia. Characteristics of body weight (BW), body length (BL), heart girth (HG), wither height (WH), hip height (HH), fore leg length (FLL), hind leg length (HLL), head length (HeL), head width (HW), ear length(EL), ear breadth (EB), tail length (TL), scrotal length (SL) and scrotal circumference (SC) were gathered. In a single parameter as body weight of Katjang bucks at below 1 year, 1-2 year and > 2 years ages were recorded to be 7.41 ± 0.27, 14.20±0.20 and25.83 ± 0.99 kg, respectively. On the hand, body weight of Katjang does at 1-2 year and > 2 years ages were observed to be 12.41 ± 0.41 and 23.65±0.87 kg, respectively. In both sexes, head length, head width, tail length, ear length, ear breath, body weight, body length, hearth girth, wither height, leg length, hip height increases with the increment of the age of goat. On the other hand, all the parameters contemplated found comparatively higher in bucks than that of does.  Strong positive correlation was observed between scrotal length and scrotal circumference in Katjang bucks.Bang.

Background: Hassan sheep is the third most populous breed of the five registered sheep breeds from Karnataka with limited studies on its morphological and carcass characteristics. Hence, the study was undertaken to know the present status of morphological and carcass characteristics of this breed. Methods: A total of 34 randomly selected flocks were surveyed and the data on various parameters were collected. The morphometrical data was collected on 344 sheep belonging to eight flocks from the breeding tract. The carcass characteristics were documented by slaughtering six male lambs (between nine to twelve months of age). Result: These sheep had varied coat colours viz. complete white (23.3%), white with light brown patches (58.1%) and white with black patches (18.6%) on head and neck region. It was observed that 40.4 per cent of males and only 1.4 per cent of females were horned. Atrophied ears were noticed in 2.3 per cent of these sheep. The average adult body length (cm), height at wither (cm), chest girth (cm), paunch (cm), ear length (cm), tail length (cm) and average adult body weight (kg) were 66.4±0.62, 65.03±1.45, 75.2±1.02, 76.5±1.38, 15.2±0.07, 11.5±0.07 and 32.7±2.03 in males and 63.8±0.85, 61.7±1.38, 71.8±2.32, 74.5±2.60, 15.0±0.34, 11.3±0.08 and 27.8±1.21 in females, respectively. The difference in body weight between males and females increased significantly over the age. The pre-slaughter weight (PSW), hot carcass weight (HCW) and dressing percentage recorded were 20.3±1.42 Kg, 9.5±0.23 kg and 46.80 per cent, respectively.

Much work has been reported on the chemical, physical and morphological properties of urinary Tamm-Horsfall glycoprotein (THG). Although it was once reported that cystic fibrotic (CF) individuals had a defective THG, more recent data indicate that THG and CF-THG are similar if not identical.No studies on the conformational aspects have been reported on this glycoprotein using circular dichroism (CD). We examined the secondary structure of THG and derivatives under various conditions and have correlated these results with quaternary structure using electron microscopy.THG was prepared from normal adult males and CF-THG from a 16-year old CF female by the method of Tamm and Horsfall.

Abstract We study size-at-age and sexual variability of morphometric characteristics of the marsh frog. According to the size of the body, males were divided into three size-age groups (juvenis, subadultus, adultus), females — into four groups (juvenis, subadultus, adultus, adultus-I). We found that the chronological age of frogs (skeletochronology) does not always correspond to their biological age (size and proportions of the body). We noted that the semi-adult males are reliably larger than females by mean values of 26 studied morphometric characters. Males and females of “adultus” group do not differ by linear body size, significant differences were found in body proportions (7 characters). For the females of “adultus-I” group, the mean values of 26 characters are significantly larger than for “adultus” males. The results of our study showed that with the age of the marsh frog, the level of exhibition, directionality and structure of morphometric sex differences changes.
