La investigación se realizó en la oriental provincia de Granma, área que destaca por sus resultados científicos relacionados con el comportamiento productivo de la especie bubalina en Cuba. El objetivo fue estimar el peso vivo a través de medidas corporales  en bucerros desde el nacimiento hasta los ocho meses de edad. Se registraron datos de 1 302 animales, hembras y machos nacidos de 120 búfalas  de la raza Buffalypso en  el período 2008 a 2015, las medidas corporales: alto de la cruz (AC), longitud del cuerpo (LC), perímetro torácico (PT), perímetro abdominal (PA), ancho de la pelvis  (AP), largo de la pelvis (LP) y ancho del tórax (AT) fueron medidas con cinta métrica en cm. Mientras el peso vivo (PV) fue determinado con plataforma digital, todas las maniobras se hicieron cada 30 días. Los modelos predictivos utilizados fueron: Quetélet,  PV = (PT)2 (longitud de cuerpo) (87,5); Crevat,  PV= (PT) (Longitud del cuerpo) (PA) (80) y Correa, PV= (PT)2(Longitud del cuerpo)/ 300. Los resultados comparativos por sexo arrojaron diferencias altamente significativas (P<0,001) para el PA y diferencias significativas (P<0,05) para el PT, PV, LP y LC a favor de los machos. EL modelo que mostró mejor ajuste (r2=0,96, P>0,001) combinó tres variables (PT, PA y LC), aunque el perímetro torácico solo mostró parámetros elevados (r2=0,94, P>0,001). Finalmente se concluye que las elevadas correlaciones entre las medidas corporales y el peso vivo,  demuestran  que las variables estudiadas pueden por si solas o combinadas explicar el comportamiento del peso vivo, pero la ecuación de predicción del PV (kg) a través de PT (cm) propuesta atribuye mayores ventajas para la práctica del pesaje.   The research was carried out in the eastern province of Granma, an area that stands out for its scientific results related to the productive behavior of the buffalo species in Cuba. The objective was to estimate live weight through body measurements in calves from birth to eight months of age. Data were recorded on 1 302 animals, females and males born to 120 buffaloes of the Buffalypso breed in the period 2008 to 2015, body measurements: height at the withers (AC), body length (LC), thoracic perimeter (PT) , abdominal perimeter (PA), pelvic width (AP), pelvic length (LP) and chest width (AT) were measured with a tape measure in cm. While the live weight (PV) was determined with a digital platform, all the maneuvers were done every 30 days. The predictive models used were: Quetélet, PV = (PT) 2 (body length) (87.5); Crevat, PV = (PT) (Body length) (PA) (80) and Correa, PV = (PT) 2 (Body length) / 300. The comparative results by sex yielded highly significant differences (P <0.001) for the PA and significant differences (P <0.05) for the PT, PV, LP and LC in favor of males. The model that showed the best fit (r2 = 0.96, P> 0.001) combined three variables (PT, PA and LC), although the thoracic perimeter only showed elevated parameters (r2 = 0.94, P> 0.001). Finally, it is concluded that the high correlations between body measurements and live weight show that the variables studied can, alone or in combination, explain the behavior of live weight, but the prediction equation of LW (kg) through PT (cm ) proposal attributes greater advantages to the practice of weighing.

Age And Sex

The relationships between live weight and eight body measurements of West African Dwarf (WAD) sheep were studied using 300 animals under farm condition. The animals were categorized based on age and sex. Data obtained on height at withers (HW), heart girth (HG), body length (BL), head length (HL), length of hindquarter (LHQ), width of hindquarter (WHQ), head width(HDW), and loin girth (LG) were fitted into simple linear (change in body measurement is directly proportional to weight or body size), allometric (body measurements do not necessarily change in direct proportion to weight or body size), and multiple linear regression models to predict live weight from the body measurements according to age group and sex. Results showed that live weight and body measurements of ewe were higher than that of the ram. Live weight, HG, HW, WHQ, LG, BL, LHQ, HL, and HW increased with the age of the animals. In multiple linear regression model, WHQ, LHQ, HW, HL and HDW best fit the model for sheep aged ≤1; HG, LG, BL and HDW for 2 year-old sheep; HG, BL, and HL best fit the model for sheep 3 years age group; LHQ best fit the model for sheep of 4 years of age; while HL best fits sheep that were in 5 year age category. Coefficients of determination (R2) values for linear and allometric models for predicting the live weight of WAD sheep increased with age in all the body measurements (HW, HG, BL, HL, LHQ, WHQ, HDW and LG). Sex had significant influence on the model with R2 values consistently higher in females except the models for LHQ, WHQ, LG and BL were they the same with the males. Based on R2 values, it was concluded that both linear and allometric regression models could be used to predict live weight from body measurements of WAD sheep.

One hundred and twenty West African Dwarf goats were used in this study. Observations were made from twelve different towns in Yewa North, Yewa South and Abeokuta North Local Government. West African dwarf goats were evaluated for phenotypic variation at different ages ranges from 1, 2 and 3 years. Variations in live weight and body measurements such as height at wither; body length, heart girth, fore limb length, hind limb length, face length, ear length, ear width, hip width and tail length were taken. The local government areas significantly (P<0.05, 0.001) affected body length, fore limb length, ear length, ear width, hip width and live weight. Age and sex significantly (P<0.01) affected all the body measurements. The mean live weight by age groups are 6.61 + 0.31kg, 13.10 + 0.60kg and 20.18 + 0.95kg for ages 1,2 and 3 respectively. The coat colour varied from black, brown, grey to white in WAD goats. Some colours were in patches, some uniform while others were spotted

Aims: To develop regression equations for estimation of live weight from the external morphological measurements. Study Design: CRD with non-orthogonal hierarchy. Place and Duration of Study: This study was carried out at 3 rural village communities of Bhaluka Upazila in Mymensingh district of Bangladesh from 2009 to 2013. Methodology: All animals were ear-tagged and maintained under semi-intensive management system with scheduled vaccination and de-worming. Data were collected from a baseline survey along with 3 progressive generations produced from the community foundation stocks. Body length, chest girth, wither height, hip height and body weights were measured in a same day and recorded individually from birth up to 15 month age. Body weights were measured in kilogram by a hanging spring balance and other morphological parameters were measured in centimeter by a measuring tape. The data were analyzed by "SPSS 17.0" statistical program. Results: A total of seven regression models were adopted and analysis of variance showed that all models were fitted significantly (p<0.001). The correlation coefficient was higher when multiple body measurements were included in the model. The study also revealed that when chest girth as a single body measurement was included in the model gave the highest correlation coefficient (R=0.92). For including multiple measurements, body length and chest girth are the best external body measures which exposed same correlation coefficient (R2=0.92) when included more than these two body measures in the model. The differences between actual body weight and body weight predicted from regression equation for different ages were less than 1% (p>0.05) and correlation coefficient between weights was 0.92 (p<0.01). Conclusion: There are strong correlations among morphometric body measurements. Thus, body weight can be estimated from a single or multiple body measurements by regression equation. Chest girth is the best single predictor for estimating live body weight with high accuracy.

The experiment was carried out at the Animal Farm / Department of Animal Resources/ College of Agriculture, University of Baghdad, to study the effect of using different percentage of concentrate to roughage in fattening calves .Two equal groups of Holstein Frisian calves, with age about eight months and at average weight of 228.8±21.2&227.8±9.12 kg /hd respectively. The calves placed in two neighboring barn. The animals fed by 3% live weight in the first two weeks then the ratio was raised to 4% of the live weight to the end the experiment. The animal’s weights and some body measurements were recorded at the beginning of the experiment, then after two weeks until the end of experiment (body wt., Chest circumference, withers height, abdominal circumference, body length). The average daily gain in the first group was 0.957 kg/hd while the average daily gain was 0.970kg/hd in the second group. In the end of experiment the weight of calves in the first group were 1428 kg / Group, while the weight in the second group was 1430 kg / group.. The amount of roughage consumption in the first and second group 1594.4 and 1070.6 kg, While the amount of concentrate consumer in the first group 1064kg and the second group was 1549.8kg. It can be concluded from this study that the use of alfalfa hay to feed concentrate diet at the level of 60 : 40 from daily feeding in the fattening Holstein Frisian calves at the age of eight months is the best because it reduces the costs and to achieve the desired purpose.

It is established that milk mares of the Kazakh horse of the Aday breed have on average live weight of 389.2 kg, height at the withers of 139.2 cm, an oblique body length of 142.1 cm, a chest girth of 167.6 cm and a metacarpus girth of 17.5 cm. Mares of the Kazakh breed of the Mangystau population surpass in the live weight and body measurements the peers of Aday offspring. Namely, the live weight was 415.3 kg, the height at withers – 140.9 cm, the oblique body length – 143.4 cm, the chest girth – 170.5 cm and the metacarpus girth - 18.3 cm. In general, mares of the Kazakh horse of the Aday offspring are inferior to the minimum requirements for animals of the elite class in height at withers, the chest and metacarpus girths. At the same time, 90% of mares correspond to the 1 quality class. In stallions – producers of the Kazakh horses of the Aday offspring, the live weight averaged 438.7 kg, and in stud horses the Mangystau population – 449,8 kg. Body measurements in Aday horses were 145.2-147.5-169.8-18.5 cm, in the Mangystau population – 145.6-148.1-172.2-18.5 cm, respectively. Some regularities of growth and development of foals from birth to 30 months of age are established. A scale for the development of young Aday horses has been developed.

The objective of this study was to predict bodyweight and estimate body measurements of Limousin cattle using digital image analysis (DIA). Body measurements including body length, wither height, chest depth, and hip height of cattle were determined both manually (by measurements stick) and by using DIA. Body area was determined by using DIA. The images of Limousin cattle were taken while cattle were standing in a squeeze chute by a digital camera and analysed by image analysis software to obtain body measurements of each animal. While comparing the actual and predicted body measurements, the accuracy was determined as 98% for wither height, 97% for hip height, 94% for chest depth and 90.6% for body length. Regression analysis between body area and bodyweight yielded an equation with R2 of 61.5%. The regression equation, which included all body traits, resulted in an R2 value of 88.7%. The results indicated that DIA can be used for accurate prediction of body measurements and bodyweight of Limousin cattle.

Heart Rate Recording

The aim of the study was to validate the heart rate (HR) recording method against whole body indirect calorimetry in prepubertal children. Nineteen 10.5-yr-old healthy children (10 boys, 9 girls) participated in this study. HR and energy expenditure (EE) were recorded through laboratory tests. Individual relationships between HR and EE were computed (equation established in laboratory). Several models were tested and validated from 24-h measurements of EE and HR by whole body indirect calorimetry. The best fit was obtained with individual polynomial relationships. Mean differences between predicted (equation established in laboratory) and measured total daily EE averaged 7.6 +/- 20.1%. The causes of the differences and the means of improving the accuracy of the prediction equation are discussed.

Dairy Breed

The productivity cow dairy breed largely depends on the careful evaluation and selection of animals by milk production and the type of exterior. The estimation of animals by measuring of body plays an important role in plant-breeding work in the process of further improvement of the newly formed Ukrainian dairy breeds by the type. It’s because exterior is one of the main signs of breeding dairy cattle together with indicators of milk production, reproductive ability and productive longevity. The aim of research was to investigate the formation of milk productivity of cows black and white dairy cattle based on their body measurements after the first calving. The research was done on animals Ukrainian black-and-white dairy breed in the «Milk River» farm in the Sokal and Brody offices breeding reproducers «Breeder» Lviv region and plant-breeding «Yamnytsya» Ivano-Frankivsk region. The body measurements of first calving cows (height at withers and depth of chest, breast width, chest girth, scythe body length, the width of the pelvic bones and metacarpus circumference cow) and milk productivity (the milk yield, fat content in milk and milk fat) cows first, second, third and better lactation were studied by the materials zoo technical accounting. The force of influence on performance metrics was calculated by Single-factor disperse analysis method. The results of research were treated by variational statistics by G.F. Lakin. Established that the milk yield of cows Ukrainian black-and-white dairy cattle depends on body measurements after the first calving. The cows Ukrainian black-and-white dairy breed in Western Ukraine that after the first calving had a height at the withers 134-136,9 cm, depth of chest – 76 cm or more, chest width – 47 cm or more, chest girth by shoulder blades – 196-203,9 cm, scythe body length – 160-164,9 cm, the width of the pelvic bones – 53 cm and metacarpus circumference cow –19-20,4 cm, are the most productive. Animals with these measurements of the body most of the largest number of yield milk and milk fat had probable advantage over cows with other indicators of these measurements. By the fat content in milk by the first, second, third and better lactation there was no significant difference between animals with different body measurements after the first calving in most cases. Among the studied parameters milk productivity of cows and measurements of their bodies after first calving we found varying strength and direction of correlation. The correlation coefficients between body measurements firstborns and yield milk by the first, second, third and better lactation were positive and depended on measurements and lactation ranged from +0,297 to +0,478. Between such measurements of firstborns, as the height at the withers, the depth of chest, width of chest, chest girth in blades, the width of the pelvic bones and with fat content in milk for the first, second, third and better lactation correlation coefficients were though low, but positive, and dependently on measurements and lactation were within +0,026 – +0,109. The correlation coefficients between the oblique body length after the first calving cows and fat content in milk were negative (-0,045 – -0,005) and between metacarpus circumference and fat ranged from negative to positive values (-0,038 – +0,017). The correlation coefficients between measurements body in firstborn and milk fat yield in the first, second, third and better lactation were positive and dependently on measurements and lactation ranged from +0,288 to +0,473. The likely positive correlation coefficient between soundings article body and yield milk and milk fat yield indicates that selection of cows by exterior will ensure the effectiveness of selection by milk productivity. The impact of body measurements cows after first calving on the milk yield value dependently on lactation yield was 7,6-22,9 %, on the yield of milk fat – 7,1-22,9 %. The greatest influence on these indicators were height at the withers, the depth of the chest, chest girth shoulder blades and scythe body length, somewhat lower impact had breast width and the width of the pelvic bones and lowest – metacarpus circumference. The impact of body measurements cows after first calving on the fat content in milk was negligible and, dependently on measurements and lactation ranged from 0,1 to 1,6 %.
