Resumo: O objetivo deste trabalho foi estimar as exigências nutricionais em energia para ganho de peso de cabritos ½ Boer x ½ Anglo Nubiana em pastejo na região Semi-árida. Foi desenvolvido na unidade experimental ?Nupeárido?, no município de Patos-PB, com 22 cabritos, com peso vivo inicial de 15 kg, em pastejo, distribuídos em quatro tratamentos com níveis crescentes de suplementação concentrada (0, 0,5, 1,0 e 1,5% do peso vivo). Ao final do período experimental os animais foram abatidos após jejum prévio de 16 h. As exigências nutricionais de energia líquida para caprinos ½ Boer x ½ Anglo Nubiano, submetidos a pastejo no semi-árido, em crescimento variam de 1,91 a 2,74 kcal/g de ganho, para animais de 15 a 30 kg de peso vivo.
[Nutritional requirements of net energy of body weight gain for goat kids on pasture]
Abstract: The objective of this work was to estimate the nutritional requirements in energy for body weight gain of ½ Boer x ½ Anglo-Nubian goat kids on pasture in the Semi-arid region. It was developed in the Experimental unit ?Nupeárido?, in Patos-PB, with 22 goat kids, with initial body weight of 15 kg, maintained on pasture and distributed into four treatments with increasing levels of concentrated supplementation (0, 0.5, 1.0 and 1.5% of the body weight). At the end of the experimental period the animals were slaughtered after previous fast of 16 hours. The nutritional requirements of net energy for ½ Boer x ½ Anglo-Nubian goat kids, submitted to pasture in the semi-arid vary from 1.91 to 2.74 kcal/g of gain, for animals from 15 to 30 kg of body weight.

Background: Most studies on granulosa cell (GC) function in cattle have been performed using GC and follicular fluid (FF) samples collected from slaughterhouse ovaries. Using this approach, the follicular developmental stage and functional status are unknown and indirectly inferred, limiting data interpretation. Ultrasound-guided follicle aspiration has previously been used to recover GC or FF samples, but this was mostly carried out in large follicles or pools of small follicles, without recording the efficiency of recovery. The present study was aimed at adapting and evaluating an ovum pick-up (OPU) system for the in vivo recovery of FF and GC from individual follicles of different diameters. Methods: In the first trial, the losses of fluid inside the tubing system were calculated using a conventional or an adapted-OPU system. Blood plasma volumes equivalent to the amount of FF in follicles of different diameters were aspirated using a conventional OPU Teflon circuit. The OPU system was then adapted by connecting 0.25 mL straws to the circuit. A second trial evaluated the efficiency of FF recovery in vivo. Follicles ranging from 4.0 to 16.8 mm in diameter were aspirated individually using the conventional or adapted-OPU systems. A third trial assessed the in vivo recovery of GC and the subsequent amount of RNA obtained from the follicles of different diameters from Holstein and Gir cattle. Results: In Trial I, the plasma recovery efficiency was similar (P > 0.05) for the volumes expected for 12 and 10 mm follicles, but decreased (P < 0.05) for smaller follicles (45.7+/-4.0%, 12.4+/-4.3% and 0.0+/-0.0% for 8, 6, and 4 mm follicles, respectively). Using the adaptation, the losses intrinsic to the aspiration system were similar for all follicle diameters. In Trial II, the expected and recovered volumes of FF were correlated (r = 0.89) and the efficiency of recovery was similar among follicles <12 mm, while larger follicles had a progressive increase in FF losses that was not related to the tubing system. In Trial III, the number of GC and amount of RNA obtained were not affected (P > 0.05) by follicle size, but differed according to breed (615,054+/-58,122 vs 458,095+/-36,407 for Holstein and Gir, respectively; P < 0.05). Conclusions: The adapted-OPU system can be successfully used for the in vivo collection of FF and GC from follicles of different diameters. This will enable further endocrine, cellular, and gene expression analyses.
