“…HG was the body measurement with the highest degree of association (0.93) with body weight (p < 0.01). These results corroborate recent studies that have demonstrated that the greater the HG of the animal, the heavier it is, and this measurement can be employed as an indicator of body weight (MENEZES et al, 2008;REIS et al, 2008).…”

“…Therefore, values closer to the observed weight were verified, because when height measurements are used to estimate the body weight, one considers the size of the animal. These results corroborate Menezes et al (2008), who indicated the height at the rump as the most convenient method for describing the skeletal size of bovine, since this measurement is more precise than height at the withers, because of the animal position, which must be appropriate.…”

ABSTRACT. This study evaluated the effect of different protein sources (soybean meal, cottonseed meal, peanut meal and sunflower meal) on dry matter and nutrient intake, productive performance and body measurements of dairy heifers, Holstein x Zebu, recreated in confinement. The experiment consisted in a randomized complete block design made up by 6 replications and 4 treatments. The mean values of ingestion of ether extract (EEI, kg day -1 ) were statistically different (p < 0.05). The neutral detergent fiber intake (NDFI, %BW) also presented differences (p < 0.05), with higher values in the diet containing sunflower meal (1.01% BW) in relation to the diet with soybean meal (0.84% BW). The average daily weight gain using the diet with soybean meal was superior (0.95 kg day -1 ) to the diet with sunflower meal (0.82 kg day -1 ), and considering the final body weight, the diet with soybean meal was superior to the other treatments (p < 0.05). The heart girth presented greater association with body weight (0.93). The soybean meal promoted the best productive performance of crossbred Holstein x Zebu heifers fed diets based on sugarcane. However, cottonseed meal, peanut meal and sunflower meal can be possible alternatives to soybean meal.Keywords: body measurement, daily gain, protein concentrate, sugarcane.Consumo de nutrientes, desempenho produtivo e medidas corporais de novilhas leiteiras alimentadas com diferentes fontes proteicas RESUMO. Objetivou-se avaliar o efeito de diferentes fontes proteicas (farelo de soja, farelo de algodão, farelo de amendoim e farelo de girassol) sobre o consumo de matéria seca e nutrientes, desempenho produtivo e medidas corporais de novilhas leiteiras, mestiças Holandês x Zebu, recriadas em confinamento. O delineamento experimental foi em blocos completos casualizados, constituído por seis repetições e quatro tratamentos. Os valores médios de ingestão de extrato etéreo (IEE, kg dia -1 ) apresentaram diferença estatística (p < 0,05). A ingestão de fibra em detergente neutro em % do peso corporal foi superior (p < 0,05) na dieta com farelo de girassol (1,01 %PC) em relação à dieta com farelo de soja (0,84 %PC). O ganho médio de peso corporal promovido pela dieta com o farelo de soja foi superior (0,95 kg dia -1

“…Even though most of the performance assessments of animals are only related to the weight, other measurements related to the body structure, such as body length, heart girth and height, are important (Menezes et al, 2008). According to Silva et al (2006), it is possible to estimate the live weight and other body aspects related to productivity through the biometric measurements of the lambs.…”

-The objectives of this study were to evaluate the environmental effects (age of dam at lambing, type of birth and sex of lamb) and genetic groups (Santa Inês and ½ Santa Inês) on weight and morphometric measurements (heart girth, body length and height) of lambs; to test linear and allometric regressions to predict the weight through the measurements; and to describe the type of growth of the measurements from weight. Weight and morphometric measurements were sampled from birth to 154 days of age, at every 14 days. For the evaluation of the environmental factors and to predict the regressions the data of birth, weaning and 154 days of age were used; and to determine the type of growth all the data collected were used. The lambs derived from younger (two-tooth) ewes recorded lower averages than the ones from eighttooth ewes for weight, heart girth and body length at birth and length at weaning. The animals born from single births presented higher average weight from birth to weaning, as well as of all the measurements from birth to 154 days of age than those from twin births. There was no difference between the genetic groups Santa Inês and ½ Santa Inês. The correlations between the weight and measurements were significant, and it was possible to predict the weight from the morphometric measurements through regressions. The type of weight gain with heart girth was isometric, while with length it was positive allometric, and with height it was negative allometric. Thereby, in the absence of a scale it is possible to predict the weight from the morphometric measurements, and the type of birth is the most important factor that affects the development of lambs from birth to weaning.

“…This assertion is based on the peaks observed in the intermediate ages and a deceleration in the growth of the crossbred animals as they aged, which followed the weight development of the animals, with the crossbred losing their superiority compared to the Charolais animals (MENEZES et al, 2008). Moreover, the rump height of the ¾ C ¼ N crossbreds was similar to the ¾ N ¼ C crossbreds at 8 and 12 months of age, however, after that the ¾ N ¼ C crossbreds became taller.…”

“…It is important to determine the pattern of measurements in the different animal biotypes, as well as the behavior of the heterosis of these traits, to help direct crossbreeding practices within commercial herds (MENEZES et al, 2008). The objectives of the present study were to examine the effects of the mating system, the genetic groups within each mating system, and their interactions on the morphometric development of male beef cattle from 8 to 24 months of age, and to measure the resulting heterosis.…”

In the present study, the effects of genetic group and heterosis on body measurements of purebreds (Charolais -C and Nellore -N), first-generation crossbreds (G1) (½ C ½ N and ½ N ½ C), and second-generation crossbreds (G2) (¾ C ¼ N and ¾ N ¼ C) males from rotational crossbreeding were evaluated at 8, 12, 18, and 24 months of age. Among the purebreds, the Nellore displayed greater rump height than the Charolais. The Charolais had greater thoracic perimeter than the Nellore, however this difference decreased gradually with advancing age, being equal between the two genetic groups at 24 months. For width of the rump, ischial opening and thoracic perimeter crossbred animals showed higher values than the purebred animals at all ages, but less pronounced at eight months of age. For all morphometric measurements, with exception of rump height, the differences of crossbreds males in relation to the purebreds, were more evident in relation to the Nellore. Heterosis was significant for morphometric measurements in male beef cattle. Morphometric measurements showed high correlation with each other and with body weight, thereby indicating that they are good indicators of body development. Key words: Bos taurus taurus.

ResumoForam avaliados os efeitos de grupo genético e heterose nas medidas corporais de machos puros (Charolês -C e Nelore -N); mestiços de primeira geração (G1) (½ C ½ N e ½ N ½ C); e mestiços de segunda geração (G2) ( ¾ C ¼ N e ¾ N ¼ C) oriundos de cruzamento rotativo. Os animais foram avaliados aos 8, 12, 18 e 24 meses de idade. Entre as raças puras, o Nelore apresentou maior altura da garupa do que o Charolês em todas idades. O Charolês foi superior ao Nelore em perímetro torácico, porém esta diferença decresceu gradativamente com o avanço da idade, sendo igual entre os dois grupos genéticos aos 24 meses. Para largura da garupa, abertura isquiática e perímetro torácico, os animais mestiços apresentaram valores médios mais elevados do que os machos puros, em todas as idades, porém menos acentuados aos oito meses de idade. Para as medidas avaliadas, com exceção para altura de garupa, as diferenças dos mestiços frente aos puros, foram mais evidentes em relação ao Nelore. A heterose se mostrou significativa para medidas morfométricas de bovinos de corte machos. As medidas corporais possuem alta correlação entre elas e com o peso corporal, sendo bons indicadores de desenvolvimento corporal. Palavras-chave: Bos taurus taurus. Bos taurus indicus. Charolês.
