Observations were made on 79 Nigerian indigenous (NI) and 24 Large White pigs.There was. a, three-month delay, in growth acceleration in NI pigs as compared with LW pigs. Growth acceleration started at 7 and 4 months for NI and LW respectively. Over all ages studied, NI differed markedly from LW in live weight, body length, height, depth and ham dimen­sions but this difference was much less between males than between females_ In NI ;boars serially slaughtered, live and carcass weights doubled between 7 and 10 months of age while dressing percent and carcass length reached peak values at 10 months. Carcass backfat measurements were higher and more consistent at the shoulder than at the loin or rump. Com­bined longitudinal and dissection studies are needed to elucidate the growth curve, the true genetic potential for growth and the body fat deposition pattern in the NI pigs.

Abstract. The present paper investigates the body length and weight, and the size-weight variations of one-month-old European catfish reared at 4 variants of stocking density: Variant 1 – 5 spec/l; Variant 2 – 10 spec/l; Variant 3 – 15 spec/l and Variant 4 – 28 spec/l. The experiment is carried out at the Institute of Fisheries and Aquaculture, Plovdiv for a period of 16 days, using a production system consisting of tubs with continuous water flow (0.7 l/min). At the end of the experiment, the fish from each variant are sorted in three size-weight groups: A – large, B – medium and C – small. The number of fish in each group is established. From the group of the medium- and small-sized fish, 150 speciments are measured, while from the group of the large specimens, which are the smallest in number, all specimens are measured for the biometric parameters body weight (BW, g) and total body length (TL, cm). The results from the study show small variations in the length and weight of the fish reared at the lowest stocking density (Variant 1). As the density increase, the size-weight differences between the specimens from Group A also increased, while of those from Group B they decrease. The number of the medium-sized fish decrease (p≤0.001) while the number of large specimens (p≤0.01) and small fish increase (p≤0.001).

AbstractThe conformation, tissue composition, and chemical composition of three types of pigs, given food ad libitum and slaughtered over a nominal live weight range of 35 to 115 kg, was assessed in relation to data provided on the live animals by a visual image analysis (VIA) system. The pig types were named as ‘3⁄4 Landrace’, ‘1⁄2 Pietrain’, and ‘1⁄4 Meishan’ types, representing ‘attenuated’, ‘blocky’, and ‘flabby’ types. Three analyses of the shape, conformation and composition data were performed. First, the relationship between conformation and age/size was assessed using linear regression of logarithmically transformed VIA and carcass data. In relation to age, ‘1⁄2 Pietrain’ pigs were found by both VIA and carcass measurements to have the widest shoulders. Both analyses also found this type to have the widest ham, trunk, and shoulders in relation to body length across most of the body length range studied, although the greatest rate of increase in ham width in relation to body length was found in the ‘1/4 Meishan’ type pigs. Second, the relationship between composition and VIA shape was examined using linear regression of transformed and standardized data. Significant relationships were found between fat, lipid, muscle, and protein weight and VIA shape, although relationships were weaker for protein and muscle weight. For fat and lipid, the VIA shape measures from the trunk region proved the most informative, whereas the VIA ham measures proved the most informative for muscle and protein. Third, detrended measures of composition/conformation and shape were used to remove the effect of animal size from the data. Removal of the variation due to growth generally led to substantial decreases in the adjusted R2statistics and in the R2-like statistics for prediction. Although in the models without detrending, relative fat and lipid weight had been found most strongly correlated with VIA shape, relative muscle was found most strongly correlated with shape in the detrended data. This was considered to result from the low between-animal variation in the data set combined with greater across-weight variation in fat and lipid weights than muscle and protein weights in the data without trend removal. Future trials with greater between-animal variation imposed would allow more precise determination of the relationship between conformation and shape.

It was found that the average live weight of geese at the beginning of the oviposition was (OS – 3% X OS – 3%): goose – 6.10 kg, goose – 7.30 kg, and (OS – 5% X OS – 5♂): goose – 6,30 kg, goose – 7,37 kg. The average weight of OS–3 goose was 39.5 eggs per head, and OS–5 – 41.4 eggs. At the same time, the average weight of eggs in the 1st group was 154.3 g, and in II – 158.5 g. The indexes of the forms in the I group consisted of: the length of the egg – 84.4 mm, the width – 55.4 mm, the index of form 65.6 in the second group respectively – 84.3 mm; 56.3 mm; 66.7 mm. The study of the incubation qualities of eggs indicates that the higher fertility was in the goose of the second group and amounted to 85.3%, which is 0.9% more compared with the I group. It is known that the yield of caterpillars is dependent on fertility and in the 1st group this indicator was 71.8%, which is 4.3% less than in the second group (76.1%). At 9 weeks of age, males of the II group surpassed their peers from the 1st group by chest covering 1.79%., With a body length of 2.08%, and a kilo length of 7.14%. The same tendency was observed in the shoots of the shin and plyusny, so the males of group ІІ in the first indicator dominated the male and group I by 8,19%; in the second indicator males of the II group dominated the males of the I group by 6.68%. At 9 weeks of age, females of group ІІ grouped over their breasts over their peers from the 1st group by 2.40%, with the body length by 3.21%., With the length of the keel – by 2.34%. Length of the leg and shoulders in the females of the 2nd group were the largest and dominated by females and groups I by the first indicator at 5.26%; in the second indicator, females of the second group dominated the females of the I group by 1.08%. Males at all investigated periods had higher levels of total protein in serum than females. It was found that males at all investigated periods had higher levels of total protein in serum than females. Performance indicators of Ohorin gray geese (Group I) consisted of: carcass weight – 39.5 pc. on the head; the weight of eggs – 154.3 g; fertility – 84.4%; deductibility – 71.8%; the live weight of geese in the 9-week-old age is 4.52 kg males and 3.84 kg females; preservation – 90.7%. Obroshinsky gray goose (group II) are characterized by the highest indexes in relation to the first group: for fertility by 4.8%, fertility by 0.9%, output by 4.9%, live weight of geese at 9 weeks of age (males) – 1.99%, (females) by 0.52%, preservation – 2.90%, egg mass – 2.64%. The highest feather-down raw material was obtained at the age of 18 in geese I group. The basic indices of blood of the examined geese were within the acceptable limits of the norm.

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.

The results of research on the overall impact of drinking water quality, microclimate parameters and adopted in the farms of FE PE “Hlyniany Agro” and LLC “Miasni Resursy” options for growing weaned young (single- and three-phase) on morphological and biochemical parameters of blood, the level of natural resistance and their growth indicates that single-phase cultivation is more favorable for the growth and development of young animals. This is confirmed by the live weight of animals at birth and at the age of 120 days. Thus, in the case of single-phase cultivation of FE PE “Glynyany Agro” the live weight of piglets at birth was 1.11 kg, and in the case of three-phase LLC “Miasni Resursy” – 1.07 kg. When the animals reached 120 days of age, the live weight of piglets was 53.2 kg in FE PE “Glynyany Agro” and 50.2 kg in LLC “Miasni Resursy”. It should be noted that according to most indicators, water quality in both farms is within acceptable limits of sanitary and hygienic requirements, although it needs to be improved. With regard to microclimatic indicators, an overestimated level of ammonia was found in FE PE “Glynyany Agro”, which exceeded the MPC by 6 and 3.33 mg/m3, respectively, in the lines and transition periods, and in LLC “Miasni Resursy” was close to its upper borders. In a farm with single-phase animal husbandry, a slight decrease in erythrocytes in the blood of piglets aged 30 and 60 days was found. Since the animals reached the 120th day of life, an increase in this indicator was noted and the number of erythrocytes in the blood of animals of both farms, within the physiological norm, was 6.47 T/l (FE PE “Hlyniany Agro”) and 7.31 T/l (Miasni Resursy LLC). The concentration of hemoglobin was low in animals of both farms, but the highest rates were in animals of FE PE “Hlyniany Agro” at 30 and 60 days of age, and at 120 days of age this figure (3.28 g/l) was higher already in piglets of Miasni Resursy LLC. The content of total protein in the blood of piglets from both farms was also low, but by the time the animals reached 120 days of age, it was already within the physiological norm. Violation of the albumin-globulin ratio with the vast majority of globulins was also noted. Regarding cellular immunity, it was noted that the content of T-lymphocytes only in animals 120 days of age was normal, exceeding the lower limit of physiological norm by 0.27 % in animals with FE PE “Hlyniany Agro” and 2.09 % in animals with Miasni Resursy LLC. Our research once again confirms that the health, growth, development, and productivity of animals are influenced by a number of factors, both hygienic and technological.

L’objectif de l’étude a été d’apprécier la conformation et certaines mensurations de la race bovine Nélore dans le but de maitriser leurs aptitudes à la reproduction. Les animaux avaient trois (3) ans d’âge. Les mensurations et la conformation ont concernées 89 génisses et 28 taurillons en stade de reproduction, sur un troupeau de 2587 têtes. Les mensurations corporelles concernées ont été évaluées par la méthode traditionnelle à la toise et au mètre ruban. Le poids vif moyen des mâles a été de 418,97 kg ± 25,84 kg et celui des femelles de 333,67 ± 33,12 kg. La robe régulière est blanche, uniforme avec des membres sombres aux extrémités chez les mâles. La conformation indique de bonnes aptitudes bouchères et les mâles sont de grande taille. La hauteur au garrot a été de 1,54 ± 0,01 m et 1,48 ± 0,03 m pour les mâles et les femelles respectivement. La longueur scapulo-ischiale a indiqué 1,89 ± 0,03 m et 1,81 ±0,02 pour les mâles et femelles respectivement. Le périmètre thoracique de 1,82 ± 0.03 m et 1,72 ± 0,03 m respectivement pour les mâles et femelles. La liaison corrélative du poids vif a été plus marquée avec la hauteur au garrot (r= 0,926) qu’avec le périmètre thoracique (r= 0,81) et la longueur scapulo-ischiale (r= 0,730). Il est donc important que les éleveurs procèdent à l’étude des mensurations et de conformation des Nelores pour bien apprécier leurs aptitudes futures de reproductions dans une ferme. ABSTRACT The objective of the study was to highlight the morphometric characteristics and conformation of the Nélore bovine breed in order to control their breeding. The animals were all about three (3) years old. The measurements and conformation involved 89 heifers and 28 breeding bulls from a herd of 2,587 heads. The body measurements concerned were evaluated by the traditional method of the measuring board and measuring tape. The average live weight of males was 418.97 kg ± 25.84 kg and that of females 333.67 ± 33.12 kg. The Common coat colour is uniform white, with dark extremities in the males. The conformation indicates good beefing abilities and the males are large. The height at the withers was 1.54 ± 0.01 m and 1.48 ± 0.03 m for males and females respectively. The scapuloischial length of 1.89 ± 0.03 m and 1.81 ± 0.02 for males and females respectively and thoracic perimeter of 1.82 ± 0.03 m and 1.72 ± 0.03 m respectively for males and females. The correlation of body weight was more marked with the height at the withers (r = 0.926) than with the thoracic perimeter (r = 0.81) and the scapuloischial length (r = 0.730). It is therefore important that the breeders study the measurements and conformation in order to appreciate the future breeding abilities of the animals on a farm.

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

Records from 120 day-old Arbor Acre (n = 60) and White Rose (n = 60) broiler strains of mixed sexes were used. The experiment was carried out at the Poultry Unit, Teaching and Research Farm of the Department of Animal Science, Faculty of Agriculture, Ahmadu Bello University Zaria, Kaduna state. Traits considered from day old to 8 weeks included body weight (BW), body length (BL) as well as chest girt (CG). The chickens were assigned to two treatments with three replications each having twenty chickens per replicate and were fed the same type of feed. The weights were taken on weekly basis. The feed consumed was also measured on daily basis. The body parameter such as body length and chest girth was also taken on weekly basis. The chick's body volume (BV) was estimated by cylinder volume using a formula derived from the work of Paputungan. Results obtained showed that age significantly (P<0.05) affected BW at all ages where the White Rose strain consistently weigh heavier than Arbor Acre. Similarly the BV of Arbor Acre is less than that of White Rose strain only at week 2. No significant difference (P>0.05) was obtained for the other parameters investigated across age. Coefficient of correlation among parameters obtained in this study were low and insignificant (P>0.05). However, all the values recorded were positive indicating that selection for any trait will lead to correlated response in the others. The multiple regression models for predicting live weight from chest girth, body length and body volume in the two strains revealed that coefficient of determination (R2 ) for BV was higher (0.96 to 0.98) compared with those of chest girth (0.56 to 0.73) and body length (0.81 to 0.88). It was concluded therefore that body volume was more efficient and better predictor of live body weight than BL and/or CG.
