RESUMO.Objetivou-se com o presente trabalho avaliar o efeito do grupo genético sobre o desenvolvimento e zoometria de caprinos leiteiros jovens. O estudo foi desenvolvido no município de Coité do Nóia, AL, mensurando-se 166 cabritos Saanen, Toggenburg, Alpina Americana, Parda Alpina, Murciana e Mestiços. A partir do desmame (60 dias), e a cada 21 dias, até 144 dias de idade, foram realizadas as pesagens dos animais e as seguintes medidas zoométricas: comprimento corporal, perímetro torácico, altura da cernelha, altura da garupa, largura de peito, largura de garupa, comprimento de garupa e perímetro escrotal. Os resultados foram avaliados por analises de variância e as médias foram comparadas pelo teste de Tukey a 5% de probabilidade. O efeito da idade sobre a zoometria foi avaliado por análise de regressão. Não houve efeito (P > 0,05) para a interação entre grupo genético e idade. Em relação à influência do grupo genético sobre a zoometria, houve diferença, onde os grupos Parda Alpina e mestiços apresentaram médias superiores (P < 0,01) aos demais grupos avaliados para comprimento corporal (51,6 cm, 50,6 cm), altura de garupa (52,7 cm, 52,5 cm), largura de garupa (10,0 cm, 10,1 cm) e perímetro escrotal (12,7 cm; 13,3 cm). Para o gênero, as fêmeas apresentaram média superior aos machos apenas para comprimento corporal (49,7 cm). O grupo genético, o gênero e a idade são fatores que influenciam o desenvolvimento e a zoometria de caprinos leiteiros jovens.

The objective of this work was to evaluate the effect of the genetic group on the development and zoometry of young dairy goats. The study was developed in the municipality of Coité do Nóia, AL. It was used measuring 166 goats kids Saanen, Toggenburg, Alpina Americana, Parda Alpina, Murciana and mixed breed animals (NDRP). After weaning (60 days), and every 21 days, up to 144 days of age, the animals were weighed and the following zoometric measures: body length, thoracic perimeter, height of the withers, height of the rump, breast width, croup width, croup length and scrotal perimeter. The results were evaluated through the analysis of variance and the mean was tested by the Tukey test at 5% probability. The effect of age on the zoommetry was evaluated by regression analysis. There was no effect (P > 0.05) on the interaction between genetic group and age. In relation to the influence of the genetic group on the zoometry, there was a difference, in which the groups Parda Alpina and NDRP presented higher

It was aimed to evaluate the effect of including the waste from passion fruit pulp extraction in diets for Japanese quail in the laying phase on their production performance and egg quality. A total of 280 female quail were distributed into five treatments with eight replicates and seven birds per cage. Treatments consisted of 0, 2, 4, 6, or 8% inclusion of passion fruit waste in the diet. The experiment began with quail at 70 days of age and lasted 63 days, with performance evaluated every 21 days and egg quality in the last two days of each cycle. There was no difference between the treatments for feed intake, body weight, specific gravity, or eggshell thickness. However, a decreasing linear regression was obtained for feed intake with the inclusion of the waste, while a quadratic response was show by egg production, weight and parts of the egg. Inclusion of up to 6% passion fruit waste in diets for quail is recommended to maintain the indices in relation to control treatment. However, the best values for egg-laying rate and for the weights of egg, albumen, yolk, and shell are obtained with 2.5 to 3.5% inclusion of passion fruit waste.

Currently, agro-industrial by-products have increasingly been used in animal feeding, as they constitute an alternative source of nutrients for the animal diet and a way to simultaneously reduce environmental pollution. The objective of this study was to examine increasing levels of inclusion of coconut cake in Japanese quail diets in the laying phase on their production performance and egg quality. A total of 360 Japanese quails were allotted to eight treatments with nine replicates and eight birds per experimental unit, in a randomized-block design. Five diets were formulated: a diet without inclusion of the by-product; and diets containing 3, 6, 9, and 12% coconut cake. The experiment lasted 63 days, with evaluations occurring at every 21 days. The following variables were analyzed: feed intake, laying rate, feed conversion, egg weight, specific gravity, Haugh unit, yolk, albumen and shell percentage, shell thickness, and shell weight. The treatments elicited a positive linear response from laying rate, whereas feed conversion per egg mass decreased linearly. In terms of egg-quality traits, shell percentage was influenced, increasing linearly. Coconut cake inclusion at 12% in the diet of Japanese quail in the laying improved feed conversion per egg mass and increased egg-laying rate and eggshell percentage.

The aim of this study was to evaluate levels of inclusion of pinto beans in diets for quail in the laying phase on their performance and egg quality. A total of 280 Japanese quail in the laying phase were distributed into five treatments in a completely randomized design with eight replicates and seven birds per plot. Treatments consisted of five levels (0, 2, 4, 6, and 8%) of inclusion of pinto beans in the diets, which remained isoenergetic and isoproteic. The experiment began with the quail at 70 days of age and lasted 63 days, with their performance assessed every 21 days and egg-quality parameters on the last two days of each cycle. The following parameters were evaluated: final weight, feed intake, egg-laying rate, feed conversion (per dozen eggs and per egg mass), egg weight, eggshell thickness, specific gravity, yolk color, and weights of shell, yolk, and albumen. No difference was detected between the bean inclusion levels for any of the performance and egg-quality traits assessed or the birds' final weight. In conclusion, up to 8% raw pinto beans may be added in diets for Japanese quail in the laying phase without compromising their performance or internal-external egg quality.
