| The association of IGF-I gene polymorphisms with certain traits in 708 individuals of two Chinese dairy-goat breeds (Guanzhong and Xinong Saanen) was investigated. Polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) and DNA sequencing methods were employed in screening for genetic variation. Two novel mutations were detected in the 5'-flanking region and in intron 4 of IGF-I gene, viz., g.1617 G > A and g.5752 G > C (accession D26119.2), respectively. The associations of the g.1617 G > A mutation with milk yield and the body size were not significant (p > 0.05). However, in the case of g.5752 G > C, Xinong Saanen dairy goats with the CG genotype presented longer bodies (p < 0.05). Chest circumference (p < 0.05)... |

| The objective of the present study was to evaluate the behavior of lactating Saanen dairy goats housed with or without the use of environmental enrichment technique. Twelve animals were split into two equal groups and assign to one of two treatments: stall with or without enrichment. Five objects were used to enrich the stalls: plastic PET bottles suspended and freely on the floor (both filled with corn as a visual and auditory stimuli), general cleaning brushes fixed to the wall of the stall, suspended tire, and a tree trunk for climbing. The behavior of the goats was observed during two hours for 10 consecutive days. The behaviors were recorded using focal-animal sampling method, observing each animal during 10-minute period. Descriptive statistics were... |

| Biomass flow characteristics and forage accumulation were evaluated in Bermudagrass (Tifton 85) pasture managed under intermittent stocking with different management strategies. The management levels utilized were conventional (10 cm residual height and unfertilized), light (20 cm residual height and unfertilized), moderate (20 cm residual height with fertilization of 300 kg N/ha.year) and intensive (10 cm residual height with fertilization of 600 kg N/ha.year). A randomized design was used with repeated measurements over time, in two periods of the year, with four replicates. There was significant effect of management × period of the year on the leaf elongation rate (LER). The management levels under fertilization (0.59 and 0.60 cm/tiller.day for the... |

| ABSTRACT This study aimed to evaluate the effects of soybean hulls (SBH) as a ground corn replacement (0, 50, and 100% SBH) on the parameters of the lactation curve and on lactation curves and milk composition. Fourteen multiparous Saanen goats were used during their lactation period, from kidding until the drying of their milk on the 228th day of lactation, and were distributed in a completely randomised design. The data was analysed using Bayesian methodology to minimise the effect of the low number of animals and to allow for comparison of the curve parameters estimated by Wood's nonlinear model. The SBH had no effect on the initial milk yield; nevertheless, the SBH reduced the rate of yield until lactation peak and accelerated the declining rate of... |

| ABSTRACT The objective of this study was to investigate the multivariate relationship among body protein, fat, and macrominerals in Saanen goats of different sexes (castrated males, females, and intact males) using canonical correlation analysis. Individual records of 274 Saanen goats combined from 10 studies was used. Two sets of body constituents were established: the first one contained variables related to body protein or fat (canonical variate U) and the second contained variables related to body calcium, phosphorus, magnesium, sodium, or potassium (canonical variate V). Two canonical pairs were identified for each sex. However, irrespective of sex, first canonical pairs accounted for more than 87% of variance of the dependent variables, these only... |

| Neste documento estão apresentados os métodos e os resultados da avaliação genética para produção de leite até 305 dias de lactação de animais (machos e fêmeas) da raça Saanen. Espera-se que a publicação deste primeiro sumário de avaliação genética do Programa de Melhoramento Genético de Caprinos Leiteiros, fruto do esforço e comprometimento de vários parceiros, mas principalmente dos criadores, converta-se num marco para a caprinocultura leiteira nacional e também sirva de convite para novas adesões a esta iniciativa. |
