Background: The fat-tailed Barbary sheep are the main breed of Tunisia and their morphometry has not been deeply investigated. This study aims to estimate the degree of relationship between eight quantitative measures across eight age classes, from one to eight years. Methods: Pearson’s product-moment was calculated to evaluate the correlation among eight morphological measures, collected from 249 purebred Tunisian Barbary ewes reared under arid climate. Result: The magnitude of pairwise phenotypic correlation among morphological traits showed a strong positive correlation (r = 0.84, P less than 0.001) between the shoulder and rump height at 6-7 years. The body weight was highly correlated to the height at rump during the first five years of age, whereas, it becomes more correlated to the heart girth when the ewe reaches its heavyweight at 5-6 years and older. The results of this study indicated that the rump height is the most correlated parameter to BW during the early life of this fat-tailed breed and are encouraging to fit live body weight from morphometric traits with accuracy.

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.

A total of 48 New Zealand White (NZW) rabbit was used for the phenotypic estimation study. After two weeks of birth, the kittens were introduced to commercial grower mash (CGM) and were fed solely on the commercial grower mash diets with the following characteristics; 17.5% crude protein, 16% crude fibre and 2500 kcal/kg diet digestible energy ad libitum. Morphometric traits such as Fore Limb (FL), Hind Limb (HL), Body Length (BL), Thigh Girth (TG), Abdominal Circumference (AC) and Leg Length (LL) in NZW rabbit were measured on the rabbit with the aid of measuring tape in centimetre (cm) at 4, 8 and 12 weeks of age. The first measurement was taken on the day of weaning (4 weeks). The data obtained was analysed using the simple linear correlation procedure of SAS analytical package to obtain the correlation between the various morphometric traits studied. The study lasted for 12 weeks. From the study the phenotypic correlations obtained were all positive and ranged between moderate (0.47, the lowest value) and high (0.89, the highest value) correlated value for all ages considered for the NZW rabbit. The result further showed that BL was highly correlated (<70) with other morphometric trait at 4 and 12 weeks of age. Moderate correlation was recorded more at the 8 weeks of age of the rabbit when compared to 4 and 12 weeks of age. The TG and HL recorded the highest correlation value among the other morphometric traits at 4, 8 and 12 weeks of age. This shows that as the animal grows, there is a positive relationship between the various morphometric traits and further implies growth is more inclined in other part of the body than FL and LL immediately after weaning while it evened out after 4 weeks of age.

The aim of the study was to investigate the effects of Moringa oleifera aqueous seed extract on live body weight, gonadal and extragonadal dimensions and sperm reserves of Yankasa rams. Twenty five apparently healthy Yankasa rams aged 1-2 years and weighing 19.0 ± 2.1 Kg were used for the study. The rams were randomly selected into five groups: A, B, C, D and E with five rams in each group as treatment and control groups respectively. Groups A - D were given oral dose of Moringa oleifera aqueous seed extract at a dose rate of 1000, 2000, 3000, 4000 (mg/kg), respectively while group E was given 10 ml/kg water orally, daily for five months. Live body weight, gonadal and extragonadal reserves were determined according to standard techniques. The results showed a significant increase in live body weight in the months of April to June among rams treated with different doses of Moringa oleifera aqueous seed extract compared with the control group. The control group showed no significant differences in the body weight, gonadal and extragonadal dimensions and sperm reserves. In conclusion, the treatment of Yankasa rams with Moringa oleifera aqueous seed extract increased live body weight, but had no significant effects on gonadal and extragonadal dimensions and sperm reserves in Yankasa rams. Therefore, it is recommended that M. oleifera aqueous seed extract can be used at doses of 2000mg/kg to 3000mg/kg in Yankasa rams for optimum gain in live body weight.

The study aimed at describing objectively the interdependence between body weight (BWT) and morphometric traits in Khaki Campbell and Pekin ducks using multivariate path analysis technique. Measurements were taken on one hundred and ninety seven (197) randomly selected 10-week old Khaki Campbell and Pekin ducks, respectively in Plateau State, Nigeria. The birds were reared on deep litter in a semi-intensive system where they were kept in a fenced area provided with water ponds and locked up in the poultry house during the night. The body parts measured were, body length (BDL); thigh length (THL); thigh circumference (THC); breast circumference (BTC); bill length (BLL); neck length (NKL); neck circumference (NKC); shank length (SHL); shank width (SHW); total leg length (TLL) and wing length (WL). General linear model was used to study genotype and sex effects. Pekin ducks had a superior advantage (p<0.05) over their Khaki Campbell counterparts in all the body parameters estimated. Sexual dimorphism (p<0.05) was in favour of male ducks.  Pairwise phenotypic correlations between BWT and morphometric traits were positive and significant (p<0.01), ranging from 0.38-0.95 and 0.35-0.92 for Khaki Campbell and Pekin ducks, respectively. Path analysis revealed that BDL was the variable of utmost importance directly influencing BWT in male Khaki Campbell and Pekin ducks (path coefficient=0.535 and 0.508, respectively; p<0.01) while BTC and SHL were the most responsible parameters affecting BWT in female Khaki Campbell and Pekin ducks [path coefficient=0.594 (P<0.01) and 1.197 (p<0.05), respectively]. The optimum regression models for the prediction of BWT in Khaki Campbell ducks included BDL, SHL, BTC and NKC (male)  and BDL, WNL and BTC (female); while in their Pekin counterparts, BDL, BLL and BTC (male) and BDL and SHL (female) were incorporated.DOI: http://dx.doi.org/10.3329/bjas.v44i1.23112            Bang.

<p>The aim of this study was to estimate the limiting litter size components in rabbit females from a Synthetic line (n=32) and a Local population (n=34). Ovulation rate, number of implanted and live embryos were counted by laparoscopy at 12 d after mating. Prolificacy (total newborn, number born alive and mortality) and embryonic, foetal and prenatal survival at day of birth of the 3<sup>rd</sup> gestation were measured. The analysed traits were body weight of the female at mating, ovulation rate, implanted, live and resorbed embryos, embryonic, foetal and prenatal survival, as well as total newborn, number born alive and mortality at birth. Synthetic line females had a higher ovulation rate compared to the Local population (11.03±0.23 vs. 8.41±0.23 corpora lutea; <em>P</em>&lt;0.0001). Synthetic line displayed a higher number of implanted embryos (10.00±0.25 vs. 7.85±0.25 embryos; <em>P</em>&lt;0.0001). No difference was found between groups for number of resorbed embryos. Similar embryonic, foetal and prenatal survival rates were reported between the Synthetic line and the Local population. Additionally, total newborn was higher in the Synthetic line than in the Local population (+1.46 kits; <em>P</em>&lt;0.05). A principal components analysis was performed. The first four principal components (PC) explained more than 90% of the total variation in both lines. Total newborn, number born alive and live embryos were the main variables defining the 1<sup>st</sup> PC. Resorbed embryos and foetal survival were located in the 2<sup>nd</sup> PC. Ovulation rate and embryonic survival were the predominant variables defining the 3<sup>rd</sup> PC. The body weight of females was located in the 4<sup>th</sup> PC. The phenotypic correlation between total newborn and its components were high and positive in both lines, except for ovulation rate and total newborn, where it was moderate in Synthetic line. In conclusion, the females from Synthetic line have a higher total newborn than those from Local population, as a consequence of a higher number of released oocytes and embryos that successfully reach implantation. However, a higher uterine crowding in Synthetic line seems to limit survival of foetuses that reach term of gestation, while ovulation rate is the principal limiting factor of total newborn in Local population.</p>

It is related leg problems to the realization of the necessity of doing a detailed analysis of the phenotype correlations between body weight and exterior measurements. As a result of the study, lower coefficients have been obtained of the correlation between the girth of the tarso metatarsus on one hand, and the body weight and the girth behind the wings, on the other hand (respectively 0.563 and 0.608), compared with the one between the body weight and the girth behind the wings (0.898). It is advisable in the selection of ostriches to take into consideration the necessity of a higher phenotypic correlation between the girth of the tarso metatarsus on the one hand, and the body weight and the girth behind the wings on the other hand, with a view to preventing leg problems.

Abstract. Tanjung A, Saragih HTSSG, Trijoko, Soenarwan HP, Widianto S, Mahardhika IWS, Daryono BS. 2019. Polymorphism of myostatin gene and its association with body weight traits in a hybrid of GAMA chicken (Gallus gallus domesticus Linn. 1758). Biodiversitas 20: 3207-3212. An experiment was conducted to detect SNP of the myostatin gene and its association with the body weight of hybrid chicken crossbreed from F1 Kamper and BC1 Broiler. Four F1 Kamper hens were crossbred with BC1 Broiler rooster. Day old chick (DOC) hatched were maintained for 49 days with body weight measurement every seven days. The blood samples from 49 days old chicken were taken for DNA isolation by Chelex 5% method and then amplification of the myostatin gene. PCR products were sequenced, and sequence alignment was performed using Clustal Omega to obtain SNP. The SNP obtained was analyzed by the Pearson correlation test with the body weight of forty nine-days-old chickens. The body weight of the hybrid chicken is higher than of Pelung chicken but lower than the Broiler. There are 7 SNPs in myostatin gene exons included 2 Adenine insertions, 1 Guanine deletion, and four substitutions (C2244G, G2283A, T4842G, G7378T) that yield nine haplotypes. Six haplotypes had different protein sequences with Myostatin protein, while three haplotypes were identical to Myostatin protein. The correlation analysis showed that there was a strong positive correlation (r = 0.736) between normal Myostatin protein and mutant to chicken body weight at 49-days-old. Adenine insertion to nucleotide 2099-2100 of myostatin gene had a very strong positive correlation (r = 0.800) to 49-days-old chicken body weight, although T4842G substitution had a strong negative relationship (r = -0.773) to 49-days-old chicken body weight. Adenine insertion to nucleotide 2099-2100 of myostatin gene could be a genetic marker of heavier body weight of the hybrid chicken.

Наведені результати випробування на 537 курчатах-бройлерах (635 контрольних) в умовах господарства препарату, виготовленого на основі розчину  полтавського бішофіту. У  курчат, яким давали препарат внутрішньо з водою,  порівняно з контролем, була більшою середня жива масса тіла у  43-добовому віці на 50 г, 73-добовому  – на 128 г і 111-добовому – на  103 г. До 43-добового віку загинуло із розрахунку від  початкової загальної кількості 16 (2,9 %) курчат-бройлерів  у дослідній групі і 30 (4,72 %) у контрольній. На контрольних  курчатах-бройлерах, порівняно із дослідними, мали економію на препараті, який не застосовували, і меншій кількості  використаних  кормів, але одержано значно більше збитків   через нижчі прирости живої маси тіла та більшу кількість загиблих. Економічна  вигода  від застосування препарату лише  до 43-добового віку курчат становить 5,8 гривень на  вкладену 1 гривню. Given results of test on 537 chickens-broilers (635 of control) in terms of economy drug produced on the basis of the solution of Poltava bishofit (SPB). Drug was given chickens-broilers of 5-day age group method internally with water in 3 cycles of 24-hour intervals over 7 times in each cycle and 7-day interval between cycles. The chicks, which were given the drug, compared with the control, had a greater average live weight of the body in 43-day age of 50 g, 73-day – 128 g and 111-day – 103 g it shows its positive effect on organisms of chicks up to 2,5 months (time of observations) after the last application in 38-th days of their lives. The drugs based on the SPB will have greater efficiency in the application of the repair chicks and adult hens, i.e. those who live more than 2,5 months. The 43-day age 16 broiler died of the calculation of the initial total number (2,9 %) in experimental group and 30 (4,72 %) in the control. On control broilers, compared with research, savings on the drug, which is not used, and smaller amounts of used feed, but we received much more losses due to lower increases in live body weight and more fatalities. The total value of the economic benefits of the drug only to 43-day age of chicks is 5,8 UAH on each invested 1 UAH.

Abstract: The left atrial volume (LAV) can be obtained using the biplane Simpson's method via echocardiography. Although in medicine this parameter has been considered to be a prognostic marker of left atrial enlargement in several cardiac diseases, in dogs with myxomatous mitral valve degeneration (MMVD), a valvulopathy characterized by left atrial (LA) volume overload, atrial enlargement is usually assessed by the LA-to-Aorta ratio (LA:Ao). Therefore, the body surface area (BSA)-indexed LAV was measured in healthy dogs and in dogs with MMVD using the biplane Simpson's method. For this purpose, a total of 107 healthy dogs (control) and 81 dogs with MMVD in ACVIM stages B1, B2 and C were assessed, with LAV being calculated during atrial diastole (d) and systole (s) through the biplane Simpson's method. Two-dimensional apical four-chamber (4C) and two-chamber (2C) images were obtained in every dog through the left parasternal window. The values obtained from healthy dogs were correlated with body weight using Pearson's test. An analysis of variance (ANOVA) and Tukey's test were used to compare healthy and MMVD dogs, as well as to investigate differences according with MMVD stages. A strong positive correlation was documented between either LAVd (r> 0.77) or LAVs (r> 0.73) and body weight in healthy dogs. The BSA-indexed LAV calculated for MMVD dogs was significantly different (p<0.01) from that obtained for the control group. Also, LAV was significantly different (P<0.05) when stages B2 and C, and B1 and C were compared. In conclusion, this study provided a reference for left atrial volume and the applicability of this technique to assess atrial overload in dogs with varying-stage MMVD.

Abstract Computer vision systems (CVS) have many applications in livestock, for example, they allow measuring traits of interest without the need for directly handling the animals, avoiding unnecessary animal stress. The objective in the current study was to devise an automated CVS for extraction of variables as body measurements and shape descriptors in pigs using depth images. These features were then tested as potential predictors of live body weight (BW) using a 5-fold cross validation (CV) with different modeling approaches: traditional multiple linear regression (LR), partial least squares (PLS), elastic networks (EL), and artificial neural networks (ANN). The devised CVS could analyze and extract features from a video fed at a rate of 12 frames per second. This resulted in a dataset with more than 32 thousand frames from 655 pigs. However, only the 580 pigs with more than 5 frames recorded were used for the development of the predictive models. From the body measures extracted from the images, body volume, area and length presented the highest correlations with BW, while widths and heights were highly correlated with each other (Figure 1). The results of the CV of the models developed for predictions of BW using a selected set of the more significant variables presented mean absolute errors (MAE) of 3.92, 3.78, 3.72, and 2.57 for PLS, LR, EN, and ANN respectively (Table 1). In conclusion, the CVS developed can automatically extract relevant variables from 3D images and a fully connected ANN with 6 hidden layers presented the overall best predictive results for BW.
