The aim of this study was to identify the average of productive and reproductive traits in Red Sindhi females and evaluate if there is an influence of the reproductive traits on milk yield in this breed. Data related to reproductive and productive traits of 638 Sindhi breed dairy cows from North, Northeast, Midwest and Southeast regions of Brazil were provided by ABCZ. Analysis of variance followed by analysis of correlation among reproductive traits and between these and milk yield traits were used. Averages for age at first calving (AFC), calving age (CA), calving interval (CI), reproductive efficiency (RE), dry period (DP), lactation period (LP),milk yield (MY), and total milk yield (TMY) were 1549.
The aim of this study was to evaluate the effect of replacing soybean meal by urea in the diet of housed Saanen young goats on performance, carcass and meat characteristics. Eighteen Saanen young males were used, with an initial average weight of 21.68 ± 0.83 kg for the treatment with soybean meal and 20.89 ± 0.61 kg for the treatment with urea, distributed in a completely randomized design. The total weight gain and the slaughter weight, as well as the carcass and commercial cuts yield were not altered by the replacement of soybean meal with urea (p > 0.05). However, there was less fasting weight loss in the diet containing urea (p = 0.01). The meat quality characteristics were also not changed by the total substitution of soybean meal for urea (p > 0.05). The replacement of soybean meal with urea does not compromise the performance, carcass characteristics and the meat quality of housed Saanen young goats.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
