Evaluation of a YouTube channel for scientific disclosure on agribusiness / Avaliação de um canal no Youtube para divulgação científica de assuntos relacionados ao agronegócio

This research analyzed the efficiency of a channel on the YouTube platform as a strategy for scientific dissemination and rural extension. The channel was created at the end of 2018 and the last video published in March 2021, totaling 58 videos. Through the metrics made available by YouTube Analytics, the information related to the channel, the audience, the searches on the platform and the engagement of the public were analyzed. Regarding the channel's metrics, an average of 15 minutes of total viewing duration, 144 subscriptions obtained and 8 lost. The audience metrics show that the channel has WhatsApp ©, Gmail ©, university website and Google© research as its main external sources. Furthermore, there is an audience, mostly female, Brazilian, between 18 and 24 years old, with access mainly by cell phone, computer and TV. The channel searches were more relevant than those coming from the platform itself, in addition to direct or unknown origin, they had a longer average duration and hours watching, but a lower viewing rate. In the engagement, the use of the elements of the final screen was positive and more used after such confirmation, in addition, in the majority of the videos, they generated positive interactions with a majority of "I liked" instead of "I didn't like". We concluded, therefore, that in matters of scientific dissemination, the channel gained relevance when observing the growing metrics in relation to the public, while the rural extension also, however, with the participation of younger producers, requiring analyzes of how to reach the other age groups. Furthermore, it highlights the need for further research to understand better ways of engaging the public.

Esta pesquisa analisou a eficiência de um canal na plataforma YouTube como estratégia para divulgação científica e extensão rural. O canal foi criado no final de 2018 e o último vídeo publicado em março de 2021, totalizando 58 vídeos. Por meio das métricas disponibilizadas pelo YouTube Analytics, foram analisadas informações referentes ao canal, audiência, buscas na plataforma e engajamento do público. Em relação às métricas do canal, obteve-se uma média de 15 minutos de duração da visualização total. As métricas de audiência mostraram que as principais origens externas do canal são o WhatsApp©, Gmail©, sites universitários e a pesquisa do Google©. Constata-se um público majoritariamente feminino, brasileiro, entre os 18 e 24 anos de idade, com acesso principalmente pelo celular, computador e TV. As buscas do canal tiveram maior relevância em comparação àquelas oriundas da própria plataforma, além de origem direta ou desconhecida e apresentaram maior duração média e horas assistidas, porém, menor taxa de visualização. No engajamento, a utilização dos elementos da tela final foi positiva e mais utilizada após tal constatação, além disso em sua maioria os vídeos geraram interações positivas com uma maioria de "Gostei". Conclui-se, portanto, que em questões de divulgação científica o canal obteve relevância ao constatar as crescentes métricas em relação ao público. Quanto à extensão rural, foram atingidos principalmente produtores jovens, necessitando análises de como atingir as demais faixas etárias. Ademais, ressalta-se a importância de continuidade da pesquisa para entender melhores formas de engajamento do público.

In ovo feeding: a review / Alimentação in ovo: uma revisão

The poultry industry plays a large role in the Brazilian economy. In fact,Brazil ranks as the worlds leading exporter and second largest producer ofpoultry meat as the result of genetic improvement, animal nutrition,management, and biosecurity. During the development of bird embryos, thenutrients are stored within the egg, but carbohydrate supplementation isunsatisfactory upon hatching. Poor carbohydrate supplementation candamage the embryo development and negatively affect poultry weight. Inovo feeding is a promising technique to improve the quality of newly hatchedchicks as it uses systems for feeding the embryos by inoculating nutrientsinto the egg amniotic fluid. However, further studies are needed in order toimprove this technique and create effective implementations and protocolsthat can be widely used in the industry. This study aims to both review theliterature on the use of in-ovo feeding and understand the perspectives ofits use in the broiler production chain.

A avicultura tem tido papel expressivo na economia brasileira, estando o país classificado como o segundo maior produtor e o maior exportador do mundo. Esse resultado é proveniente de avanços no melhoramento genético, nutrição, manejo e biosseguridade. Nas aves, os nutrientes utilizados durante o desenvolvimento embrionário estão contidos no ovo, sendo escassa a reserva de carboidratos logo após a eclosão do pintainho. Essa restrição pode causar prejuízos ao desenvolvimento embrionário, impactando negativamente no peso das aves. Diante disso, a nutrição in ovo mostra-se como uma técnica promissora, que visa prover nutrientes ao embrião por meio da inoculação de soluções com efeitos benéficos ao seu desenvolvimento. Contudo, são necessários mais estudos no intuito de aprimorar a técnica e criação de protocolos efetivos que possam ser amplamente utilizados pela indústria. Nesse contexto, o objetivo desta revisão de literatura foi abordar e depreender as perspectivas da utilização da técnica nutrição in ovo na cadeia produtiva de frangos de corte.

Flavored sisal ropes as environmental enrichment for nursery piglets

The objective of the present study was to evaluate the behavior of piglets in the nursery phase in the presence of pure sisal ropes, soaked with different flavors as a means of environmental enrichment. Sixty-four piglets with 35 days of age in the nursery phase were used, piglets were randomly distributed in a completely randomized design in 16 pens, with four animals in each pen and there was no separation of pens by group. Three treatments were used: Pure rope (PR) which was considered the control of the pen, rope soaked in vanilla essence and sugar (SV), and rope soaked in coffee (SC). An ethogram was prepared for observations of the following behavioral parameters, eating, drinking, urinating, defecating, lying down, standing, playful, and others. The parameters were measured every 10 minutes in a total of three daily assessments with two hours each for a period of three days. There was a greater preference of piglets for the SV rope with a percentage of 63.2% in the observations of the interactions. A possible justification for the result is the fact that this rope is the most palatable for piglets since piglets prefer sweet tastes. The PR rope aroused curiosity in the piglets, with a percentage of observations of 21.4%. Therefore, the use of equipment flavored with sweet vanilla taste is promising as a means of environmental enrichment, being more interesting to piglets.(AU)
