The objective was to evaluate lipid sources, as a strategy to reduce feed costs, whether or not associated with Spineless cactus in goat milk production. For the study, 12 lactating Saanen goats were used, with an average body weight of 55 ± 8 kg, distributed in a 4x4 Latin square, with a 2x2 factorial arrangement. The treatments consisted of two lipid sources, Coconut fruit pulp by-product (PC) and whole cottonseed (CA), associated or not with Orelha de Elefante Mexicana (POEM), in the following proportions: PC - 5% Coconut fruit pulp by-product; PC+POEM - 5% Coconut fruit pulp by-product + 25% POEM; CA – 20% whole cottonseed; CA+POEMA - 20% whole cottonseed + 25% POEMA. Animals that consumed diets that had whole cottonseed as the main source of energy showed higher performance indices (P<0.05). The PC+POEM treatment presented the lowest cost for 1 kg of dry matter (R$ 1.78). The PC diet demonstrated lower daily food costs (R$ 2.54). Total income was higher for the CA + POEM diet (R$ 8.17), as was net income (R$ 4.19). Therefore, it is recommended to combine whole cottonseed with forage palm Orelha de Elefante Mexicana, in the feeding of lactating goats, due to the reduction in feed costs, especially in roughage and better performance, contributing to greater profitability of the activity.Item Efeito da dieta basal sobre o desempenho de cabras em lactação(2023-09-11) Souza, Margot Santos de; Ferreira, Marcelo de Andrade; http://lattes.cnpq.br/4818123702136736; http://lattes.cnpq.br/4617261628043561Goat farming has increasing in Brazil, especially in the Northeast region, which is responsible for 32% of the country's total production. Due to the edaphoclimatic conditions of this region some studies are carried out trying to improve the performance of those animals. Therefore, the present study intented to evaluate the effect of different sources of fiber (corn silage, sorghum silage, pangolon hay or sugarcane bagasse) associated with cactus pear in diets for Saanen goats in lactation process on nutrient intake and digestibility, ingestive behavior, milk production and composition. The experiment was carried out at the Experimental Station of the Pernambuco Agronomic Institute (IPA) in Sertânia (Pernambuco). Twelve multiparous and lactating goats were used in this experiment with an average weight of 48.9 kg, average initial production of 2.8 kg of milk/day and lactation period of 80 days. The goats were weighed, identified and distributed according to their productivity in three simultaneous Latin squares (4 x 4), containing four animals, four treatments and four experimental periods. The 4 experimental period LASTED 21 days each, with the initial 14 days for adaptation of the animals, and others for data and sample collection (food, leftovers, feces and milk). The diets were offered ad libitum as a complete mixture, three times a day, allowing 5 to 10% of the total dry matter supplied. The goats were manually milked twice a day. For the ingestive behavior, the activity that the goat is performing (feeding, rumination or idleness) were observed every 10 minutes for 24 hours. Statistical analyzes were performed using a PROC MIXED package from SAS (2014). Intake of dry matter (2.58kg/day) and organic matter (2.30kg/day), crude protein (0.385 kg/day), ether extract (0.170 kg/day), neutral detergent fiber (0.895 kg/day), non-fiber carbohydrates (0.858 kg/day) and metabolizable energy (5.66 Mcal/day) did not differ between fiber sources that made up the basal diet (P>0.05). Fiber sources did not influence the digestibility of dry matter and nutrients (P>0.05). The association of cactus pear with silages, hay and sugarcane bagasse did not alter milk production without correction, corrected for 3.5% of fat and corrected for energy (2.78; 2.53 and 2. 55 kg/day, respectively), in addition to the composition of the milk (P>0.05). The diets did not cause changes in any of the items evaluated in the ingestive behavior (P>0.05). It is recommended that any of the fiber sources be purchased along with cactus pear in the basal diet of lactating goats.Item Proposta de um sistema de produção de leite com dietas à base de palma forrageira(2023-09-11) Melo, Gabriela Correia da Silva; Ferreira, Marcelo de Andrade; http://lattes.cnpq.br/4818123702136736Agreste de Pernambuco is home to the state's main dairy basin, accounting for approximately 75% of production. Due to the edaphoclimatic characteristics of the region (Semi-arid), characterized by low rainfall and high temperatures, challenges related to forage production must be faced in order to sustain dairy production systems in the region. Thus, the implementation of high-yielding roughage can be achieved through appropriate agricultural practices, the use of technologies, the selection of varieties adapted to the region's climate and the adoption of good management practices. In this way, fodder palm has been a valuable option for livestock farming in the Agreste region of Pernambuco, contributing to animal food security during periods of drought and offering a sustainable alternative for feeding livestock in the semi-arid region. The aim was to develop a milk production system with palm-based diets, based on the identification in the literature of the main reference indicators to be improved in order to increase the sustainability of dairy farming in Pernambuco. After identifying them and based on zootechnical indices considered achievable, a stabilized herd was idealized and diets based on fodder palm were calculated to meet the needs of this herd. Subsequently, the reference indices were recalculated and showed a significant improvement, indicating that palm can be an extremely important strategy for daisy fanning in the state.Item Análise multivariada de varíaveis ambientais, fisiológicas, parâmetros comportamentais e produção e qualidade de leite de vacas no verão(2019) Silva, Andreza Malena Guedes da Costa; Almeida, Gledson Luiz Pontes de; http://lattes.cnpq.br/2328849810614673; http://lattes.cnpq.br/0440362372584309The objective of this study was to determine, through the multivariate analysis, which, among the environmental, physiological and behavioral parameters, influence milk production and quality of lactating cows. This study was developed with data from a collection carried out in 2009. Sixteen lactating Girolando cows were selected. The animals were divided into four treatments of 0, 10, 20 and 30 minutes on a cooling system. The statistical analysis used was the multivariate, using the technique of Principal Component Analysis on the environmental, physiological and behavioral parameters have influence on milk production and quality. The rumination was opposite to the production, indicating that it was smaller, because it presents a condition of possible stress. The CCS was strongly influenced by the TR and in turn the FR. Both TR and FR presented the highest values in time of 0 minutes indicating a condition of thermal stress, which reflected in accentuated values of CCS, reducing milk quality. The use of 10,20 and 30 min cow exposure times to the evaporative adiabatic cooling system provided significant changes in somatic cell counts.Item Uso de tecnologia da informação como ferramenta de análise na gestão de indices de importância econômica na pecuária de leite(2019-01-14) Barros Filho, Otávio Bezerra do Rêgo; Almeida, Gledson Luiz Pontes de; http://lattes.cnpq.br/2328849810614673; http://lattes.cnpq.br/7286706655007971Agribusiness is one of the sectors of greater importance in the Brazilian economy and has been moving millions of reais in resources, generating thousands of direct and indirect jobs and transforming the Country into a large agrarian barn. In this sense, in search of new techniques and technologies, the Compulsory Supervised Internship was held during the period from September 18 to December 7, 2018, at the Rehagro Company, in the State of Minas Gerais, with the objective of addressing management issues rural development, as well as the use of managerial tools of important indices for dairy cattle raising. Practical activities developed especially for the financial management of agribusiness, with emphasis on the use of Information Technology (IT). During the training period, some farms were monitored for the collection of data for the elaboration of indexes capable of pointing out possible failures in production and consequent generation of resources. In particular, two cases were followed at Fazenda São João, in the municipality of Inhauma-MG. Failures in reproductive and sanitary management were detected and, through the use of tools such as Benchmarking and PDCA, it was possible to make a decision to reverse the deficit of production costs. Based on the above, it can be concluded that the implementation of a plan of action, based on the IT management and employment indices, should always be taken into account when establishing efficient production, profitability, and above all with good relations between all those involved.
