Laboratory Breeding

A laboratory breeding colony of R. l. lutreolus was used to obtain data on the growth in the length of head, hind foot, tail, head and body, and body weight during the first 130 days of life. The development of external body features was compared to that known for other Australian Rattus. The young are blind and naked at birth and are not fully furred until 13 days. Incisors are visible at day 8 (5-11) and erupt about day 12 (8-15) with the eyes opening at 17 days (15-18). Independence was achieved at about 25 days (23-30) with the first signs of reproductive maturity at about 60-70 days. Five stages of growth can be related to developmental features from teeth eruption to puberty and reproductive maturity. The onset of hearing (14-15) days appear to be as important in development as does the opening of the eyes. Body measurements show sigmoid relationships to a linear equivalence of weight (W*0.33), except for head and body length which is linear. R. l. lutreolus belongs to the fast-growing group in Australian murids. Measurements from laboratory-bred animals are in agreement with those for field animals, with head and body length the best single parameter for obtaining approximate ages.

Linear Body

Data on body weight and linear body measurements (LBMs) namely ear length (EL), body width (BW), body length (BL), Head to shoulder (HS), Shoulder to tail (ST) and length of leg (LL) of 363 progeny of locally adapted Dutch , New Zealand White and crossbred rabbits at 3,6,9 and 12 weeks of age were analyzed to obtain phenotypic correlations between the various traits and prediction equations for body weight, using different linear body measurements. There were high and positive correlations between each of the linear body measurements and body weight and between the LBM themselves. The values ranged between 0.57 and 0.85, 0.34 and 0.89, 0.27 and 0.83 and 0.41 and 0.75 in weeks 3, 6, 9 and 12, respectively. Hence, it was possible to predict body weight of live rabbits from their linear body measurements, as an aid to farmers in areas where sensitive scales are not available. Except in purebred New Zealand White NZWxNZW, body: length (BL) was a good predictor of 3- week body weight (IBW) in all breed groups. Body width (BW) and BL only were good predictors of 6-week body weight in all breed groups. For predicting 9- week body weight, shoulder to tail drop (ST) was important in all breed groups in addition to either BW, ear length (EL) or body length (BL). ST and BW were important predictors of 12-week body weight generally in all breed groups.

Heart girth (HG), body length (BL), leg length (LL), metacarpal circumference (MC), withers height (WH) and hook width (HW) of 233 growing rams of three synthetic strains, Suffolk and Finnsheep breeds were measured at 6, 8 and 10 mo of age. Thereafter, subsequent measurements were taken at 11–13 mo, 18–21 mo and 23–25 mo of age. Breed, birth period (hysterectomy derived birth date), age of ram and body weight (BW) had important effects (P < 0.05) on linear body measurements, whereas age of dam did not (P > 0.05). Significant effects of litter size on HG and BL were observed at 6 and 8 mo of age, respectively. All linear body measurements increased from 6 to 21 mo of age, whereas BL, WH and HW continued to increase to 25 mo. Rams of Strain 1, developed as a synthetic sire strain, with a large proportion of Suffolk background were generally similar to the Suffolk rams in all body measurements except for HG which was significantly larger than in Suffolk rams. The Finnsheep rams had smaller HG, BL, MC and HW than the synthetic strains and Suffolk rams, whereas LL and WH of the Finnsheep and Suffolk rams were similar. Rams of Strains 2 and 3, developed as synthetic dam strains with 50 percent Finnsheep background, were similar in body measurements. The synthetic dam strains did not differ from Strain 1 and/or Suffolk with respect to HG, BL, WH and HW. However, Suffolk rams had larger MC and shorter LL compared to those of the Strain 2 and 3 rams. Birth period had a significant effect on HG, BL, LL and MC, but no consistent trend with age of ram was apparent. Linear body measurements were positively correlated with each other and with body weight; however, the relationship varied as rams progressed in age. The importance of breed, birth date, age of ram and body weight on body measurements and the requirements for appropriate adjustments is emphasized.

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.

This study aimed to determine the Correlation and the regression equation between body measurements and body weight of Brahman Cross (BX) Cow in KPT Maju Sejahtera Trimulyo village, Tanjung Bintang District, Lampung Selatan Regency. This research was conducted in July 2020. The data obtained were analyzed using simple and multiple regression analysis using the help of the Excel program. The material used in this study were 32 Brahman Cross (BX) Cow aged 2-3 years. The results of this study indicated that the average of Body Weight (BW), Chest Circumference (CC), Body Length (BL), and Shoulder height (SH) were 472.66 � 53.59 kg, 179.95 � 7, 95 cm, 132.49 � 6.39 cm, 127.95 � 3.08 cm, respectively. The correlation value between CC, BL, SH with BB were 0.764, 0.448, and 0.551, respectively. These results indicated that CC, BL, SH, have a positive relationship with BW. The regression equation resulting from the relationship between body weight and body size CC, BL, SH to BW with the value of determination (R2) and significance (P?0.05) was 0.607 (60.7%) with the regression equation BW = -674.003 + 4.314 CC + 1.247 BL + 1.602 SH.

The pre weaning growth performance of piglets from four different cross bred dams mated back to their native parents was studied in the Breeding and Research Farm of Ebonyi State University, Abakaliki. Parameters like body weight, weight gain, feed intake and feed efficiency as well as linear body measurements of body length, heart girth and height  at withers were taken and observed for growth between birth and weaning age of eight weeks. Results Results indicated significant differences (P<0.05) between the main backcross N x (N x LR) and the three other genotypes of N x (N x LW), N x (LR x N) and N x (LW x N) in all parameters. The mean birth weight of the progenies ranged from 1.00±0.60 to 1.60±5kg while the weaning weights were 10.5±0.4 to 16.0±1.0kg respectively. Results further revealed that body weight at weaning correlated responsively with all parameters and these include body length (r=0.858), heart girth (r= 0.446) and height at the withers (r= 0.946). Similarly, body length has a positive correlation with heart girth (r= 0.477) and height at the withers (r= 0.827) whereas hear girth correlated positively with the height at the withers (r= 0.494). Similar trend were obtained in the regression of each of the body measurements on the other in which bodyweight changes depended more on that of body length (0.86) than on heart girth (0.45). Judging from the observed variations existing among the piglets resulting from differnt crossbreed dams in their pre-weaning growth performance, maternal rather than paternal influences appeared to be more important in the traits studied.

Body weight of animals in the rural areas has not been accurately ascertained due to lack of accurate measurement scales, hence this experiment. The study was conducted to determine the correlation between milk intake and body weight with linear body measurements in white Fulani calves raised in semi-intensive system of management. A total of seven (7) white Fulani calves managed semi-intensively was used for the study. The experiment lasted 12 weeks. The overall mean±SEM value for milk intake, body weight, neck circumference, neck length, body length, body circumference, girth circumference, height at wither and tail length were 1.20±0.40g, 5.18±1.02kg, 21.54±0.66cm, 13.23±0.21cm, 28.36±0.31cm, 36.41±0.43cm, 35.84±0.37cm, 35.87±0.43cm and 23.43±0.39cm respectively. There was significant (P<0.05) effect of lactation stage on all body measurements taken except for neck circumference and tail length. Correlation between all body pairs of measurements were high, positive and highly significant (P<0.05). The highest correlation was recorded for body length, body circumference, girth circumference and height at wither. Linear function provided the best fit for milk intake weight and linear body measurements indicating that body measurements can be used for selection and the estimation of body weight in the fields where accurate scales are not usually available. It is recommended that any of the body measurement parameters could be used in the estimation of the body weight. Also, an improvement of non-genetic factor such as nutrition and general husbandry of the animal as much as possible will bring about improvement in the body parameters as well as maintaining the animal's physiological balance.

This paper presents the results of the variability and correlation of body measurements and milk production of domestic Balkan goat breed that is reared in the mountain range Sharplanina, depending on the lactation. Studied animals were monitored and lactation, or order of kidding (I, II, III and IV and the next lactation together). Control of milk production, included a total of 290 goats in different lactations (first-81 animals, the second-69 heads, 71 heads third-and fourth and following along latkacije-69 heads). In order to determine the measure of body development in adult goats, one takes values for height at withers, body length, chest depth, chest width, the width of the cross and body weight. The variability of the analyzed characteristics is presented descriptive parameters and the effect of lactation is determined by a factorial analysis of variance. The determined average values for milk production and measures of body development are located within those identified for this population of goats. During these tests showed statistically significant correlation dependence (P <0.05) between all studied variables, except when it comes to length lactation period and individual measures of body development. The correlation coefficient between length of lactation and established measures of body development. are low and reflect the existence uncorrelation dependence, and their values range from 0.08 to 0.11, while they were unjustified and statistically (P> 0.05).

Greater scaup (Aythya marila) and lesser scaup (A. affinis) were collected during their spring and fall migrations at Lake St. Louis, Quebec, in 1979 and 1980. Body measurements and weights of fat deposits were obtained for 35 greater scaup and 39 lesser scaup. Carcasses were homogenized and analyzed for lipid and water content. Percent body water and skin weight were the best predictors of ether-extractable body lipids. Body weight and body weight/body length were good predictors of ether-extractable lipids but may provide less reliable estimates if used for scaup at other stages of their annual cycle. Only abdominal fat weight could be used to derive a single predictive equation estimating ether-extractable lipids for both species. Regression lines with body weight or body weight/body length as the independent variables had the same slope for both species but these differed in elevation.

The effect of the plane of nutrition in the first 13 weeks of post-natal life of cattle on their subsequent growth rate, body shape, and carcass composition up to 12 months of age was studied. No compensatory growth to 12 months of age was observed in calves reared to 13 weeks on low planes of nutrition. There were no significant differences between Friesian and Hereford x Friesian calves, or between males and females in empty body weight or weight gains. Treatment up to 13 weeks of age had no effect on heart girth, round, head length and width, and cannon bone length, but the remaining body measurements were reduced by low planes of nutrition during this period. Differences in carcass composition were largely a reflection of the differences in empty body weight. The carcasses of the males were heavier than those of the females and the females contained a higher proportion of fat. Carcass composition, as estimated by shin dissection, indicated that Friesian calves contained more muscle than the Hereford x Friesians, and the males more muscle than the females.
