The objective with this study was to evaluate the effect of including dried distillers grains with solubles (DDGS) as a replacement for soybean meal on feed intake, digestibility, and total digestible nutrients (TDN), as well as plasmatic glucose and serum urea concentrations. Fifteen Saanen goats were distributed in a completely randomized design with three treatments and five replicates. Treatments were soybean meal (SBM), SBM+DDGS (12.28% of dry matter [DM]), and DDGS (23.16% of DM), as protein source in diets, common to all corn ground and mineral-vitamin supplement, and corn silage (60% of DM). Response variables were evaluated every 30 d, from 1 to 120 d after parturition. Measurements included body weight, DM intake, DM and nutrient digestibility, and blood samples. Indigestible neutral detergent fiber was used to estimate fecal excretion. There was a difference in neutral detergent fiber intake from 1 to 30 d after parturition. In the four phases of lactation evaluated, there were treatment effects on DM, organic matter, ether extract, and total carbohydrate digestibility, as well as on TDN concentration. Neutral detergent fiber digestibility was affected by treatments, except from d 61 to 90. There was no treatment effect on non-fibrous carbohydrate digestibility, regardless of period. Therefore, SBM+DDGS (12.28% of DM), as protein source on diets may be used in Saanen goat diets from 1 to 120 d of lactation without negative effects on feed intake, digestibility, and plasma glucose and urea concentrations.

RESUMO.Este trabalho foi conduzido com o objetivo de diagnosticar o perfil do consumidor de carne de búfalo no município de Marabá-PA quanto ao conhecimento do produto e os fatores relacionados à escolha, periodicidade e quantidade de carne consumida. O diagnóstico foi realizado por meio de entrevistas com formulários online. Houve preferência no consumo de carne bovina e peixes, e a carne de búfalo mostrou-se a menos consumida, porém, uma parcela expressiva da população afirmou estar disposta a aumentar este consumo. Os motivos para não consumir carne de búfalo foram relacionados ao fato de ser uma carne pouco apreciada e falta de oferta. O desconhecimento das formas de criação, procedência, aspectos nutricionais, e possíveis formas de se comprar e preparar a carne de búfalo levou a ratificar o seu baixo consumo local, além da falta de oferta do mercado. Os consumidores de carne de búfalo consideram este um alimento saboroso e saudável, entretanto, pouco ofertada no mercado. Sugerem-se campanhas que visem o aumento da oferta e do consumo da carne de búfalos e em ações que permitam à população descobrir novas formas de preparo, consumo e mais informações nutricionais.Palavras chave: bubalinocultura, consumo de carne, produtos processados Diagnosis of the buffalo meat consumer profile in the municipality of Marabá, PAABSTRACT. The objective of this work was to diagnose the buffalo meat consumer profile in Marabá-PA in terms of product knowledge and factors related to the choice, periodicity and quantity of milk and meat consumed. The diagnosis was made through interviews with online forms. There was a preference in beef and fish consumption, and buffalo meat was the least consumed, but a significant portion of the population said they were willing to increase this consumption. The reasons for not consuming buffalo meat were related to the fact that it was a little appreciated meat and lack of supply. The ignorance of the ways of breeding, origin, nutritional aspects, and possible ways of buying and preparing the buffalo meat has ratified its low local consumption, besides the lack of market supply. Consumers of buffalo meat consider this a tasty and healthy food, however, little offered on the market. Campaigns are suggested that aim to increase the supply and consumption of buffalo meat and in actions that allow the population to discover new forms of preparation, consumption and more nutritional information.

The objective of this study was to evaluate the reproductive performance of ewes subjected to a short-term protocol for estrus induction using 1 mg of Norgestomet during the non-breeding season in Brazil. A total of 84 ewes were randomly divided into two equal groups (n = 42 per group). Controlled Internal Drug Release (CIDR) containing 330 mg progesterone was inserted into the vagina in the first 42 ewes, and for the other 42 ewes in the second group, 1 mg of Norgestomet was placed subcutaneously in the convex surface of the ear. Implants and devices were removed in both groups on day 6. Following the removal of implants and devices, 10 mg of PGF2α and 300 IU of eCG were injected in all the ewes. After 48 h of application, three fertile rams were added to the herd. Ewes and rams were kept together for four days. Rams were removed on day 12, and after 42 days, pregnancy was diagnosed by ultrasound scanning. Short-term protocols using either an intravaginal device or ear implant were similarly effective to estrus induction (95.23 vs. 92.85%), and all ewes from both groups had estrus manifestation within 72 h after implant removal (72±9 h). In addition, no significant difference in pregnancy rate was observed between ewes treated with the intravaginal device and ear implant protocols (52.38 vs. 57.14%). These results suggest that 1 mg of Norgestomet is a good alternative for short-term protocols for estrus induction/ synchronization during the non-breeding season in ewes. It is possible to replace the progesterone-releasing intravaginal device by the ear implant and obtain the same reproductive effectiveness in ewes.

The effect of pineapple by-product silage as a substitute for elephant grass on carcass yield, commercial cuts and non-carcass components was evaluated in 25 castrated male Santa Inês feedlot finishing lambs. The lambs had an initial body weight of 18.0±3.4 kg, and they were fed four pineapple by-product silage concentrations (0, 25, 50, 75 and 100%) distributed in a completely randomized design with five treatments and five repetitions. Lambs were slaughtered at a body weight of 30 kg. The hot carcass weight and hot carcass yield were recorded and chilled at 4°C for 24 h. The quantitative parameters of the carcass, the wholesale cuts expressed in kg and percentage, and non-carcass components were determined. Carcasses were divided into seven commercial cuts. The hot and cold carcass yields significantly increased when elephant grass was replaced with pineapple by-product silage in the diets. The weight of the false rib and loin cuts increased linearly when pineapple byproduct silage was added to the diets (P< 0.05). No significant differences were observed in the weights of the other cuts (P>0.05). The average weights of the non-carcass components were not affected by the addition of pineapple by-product silage, except for gastrointestinal tract (GIT) content, which decreased linearly, and omental-mesenteric, perirenal and internal fat depots, which increased linearly with the addition of pineapple by-product silage to the diets. The use of pineapple by-product silage as a substitute for elephant grass in growing lamb diets is recommended because it did not negatively affect the carcass characteristics, commercial cut yields or non-carcass components.
