The experimental design was completely randomized, testing different levels of inclusion of whey and live Lactobacillus strains based on forage green matter, constituting the following treatments: 1) Sorghum without inclusion of additives (CON); 2) Sorghum + 5 x 102 cfu/g L. casei and L. acidophillus (LAC); 3) Sorghum 5 x 102 cfu g-1 whey (SL); 4) Sorghum + 5x102 cfu/g-1 L. casei and L. acidophillus and 5x102 cfu/g whey (LAC + SL). When Lactobacillus was included the mixture used was 50 ml of water and 10 grams of Lactobacillus. To measure silage fermentation, pH, dry matter recovery, gas and effluent losses, ammonia nitrogen, buffer power and density were estimated. The addition of whey and Lactobacillus inoculant in sorghum silage did not significantly change the bromatological values of silage when compared to the original material. The inclusion of additives increased (P <0.05) the effluent losses during fermentation. The use of whey presents a viable alternative for producers, as it does not compromise the fermentation and chemical composition of sorghum silage and assists in the reduction of dairy residues in nature.","PeriodicalId":43616,"journal":{"name":"BOLETIM DE INDUSTRIA ANIMAL","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2019-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47662988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The semi-standardized, non-probabilistic and finite population sampling methodology was used. The research was carried out with 35 producers (90% confidence interval and 10% margin of error). The properties were grouped into three production strata: 0 to 200 liters / day; From 201 to 500 liters / day; And above 501 liters / day. Most dairy farmers are over 50 years old and over 20 years of experience in this activity. Of the total only 7 producers were under 40 years of age. The production systems are semi-intensive, where the animals are raised in cultivated pasture and receive feed and corn silage after the milking. This system, coupled with good animal genetics and adequate sanitary management, promotes an adequate production of animal milk / day. Much of the income of the municipality of Pejucara is derived from the dairy activity, so the extension work serves as a support in the decision making aiming at improvements in the critical points and the improvement in the positive points in the diverse properties of the municipality.","PeriodicalId":43616,"journal":{"name":"BOLETIM DE INDUSTRIA ANIMAL","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2019-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49429900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-four crossbred lambs, 3 month-old and initial body weight of 25.97 ± 0.75 kg, were kept in individual pens. They received one of the following diets: control (no oilseeds, 3.01% Ether Extract - EE), with cottonseed (6.86% EE), sunflower seed (6.93% EE), or soybean (4.75% EE). All diets contained 23.63% of coast cross hay and 76.37% of concentrate. After 84 days of feedlot, the animals were slaughtered and the carcasses evaluated. The dry matter intake and daily weight gain of animals fed with control diet was higher than with oilseeds (P≤0.05). Final body weight and carcass weight were higher (P≤0.05) with control (42.42 kg and 19.27 kg, respectively) than sunflower diet (34.85 kg and 16.05 kg, respectively).

All steers were fed ad libitum for 78 days (Phase 2). Body composition was estimated with the marker deuterium oxide, which allowed repeated measurements of the same animal and to study of its response to re-alimentation. Average daily gain in restriction phase reflected different weight gain rates provided by feed levels, being them 0.288 kg, 0.656 kg and 1.169 kg, respectively for 60g DM/ BW0.75, 75g DM/ BW0.75 and ad libitum.

The objective was to evaluate the soil enzymatic activity in the Brachiaria pastures managed under the forage allowances of 4, 7, 10 and 13 kg MS/100 kg BW. The grazing method adopted was mob-stocking, with four grazing cycles (between December 2008 and February 2009). We also performed a sampling in June 2009 for better characterization, as the mineralization of soil organic matter occurs in the long term. The experimental design was completely randomized, with three replications and time subdivided plots. Forage allowances did not maintain a pattern of the activity of the enzyme’s dehydrogenase, protease, arylsulfatase and cellulase. Among the cv., there was a greater (P<0.05) activity of dehydrogenase and arylsulfatase in the cv. Marandu. Activity of dehydrogenase observed was 169,90; 189,19; 185,65; 247,74; and 126,00 μg TFF/g soil, and arylsulfatase was 29,69; 31,19; 38,14; 34,22; and 38,33 μg paranitrofenol/g soil, respectively to 1, 21, 42, 63, and 183 evaluation days. The protease activity was higher (P<0.05) for cv. Marandu, with the exception of evaluation day 42, where the highest activity was for cv. Mulato (82,38 μg tirosina/g soil). For cv. Marandu, the protease activity obtained was 80,49; 108,23; 86,01; and 134,71 μg tirosina/g soil solo, respectively to 1, 21, 63, and 183 evaluation days. Marandu cultivar is the most indicate to promove better conditions for the microorganisms responsible to the enzymatic activity of dehydrogenase, arylsulfatase, and protease. It can be inferred that a longer study time is required in order to increase the specificity of the forage allowances in relation to the behavior of the enzyme activity.","PeriodicalId":43616,"journal":{"name":"BOLETIM DE INDUSTRIA ANIMAL","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2019-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42153551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forty lactating Caracu cows (a locally adapted Bos taurus taurus breed) grazing on Panicum maximum cv. Tanzania and supplemented with corn silage received the equivalent of 0.5 mg/animal/day of MGA for 14 days. On day 5, the animals were randomly assigned to one of two groups: group 1 (n=21) received an im injection of 2.0 mg ECP and group 2 (n=19) received 2 ml saline. Animals of group 1 that exhibited estrus within 120 hours after withdrawal of MGA were inseminated (AI), while animals of group 2 were treated with cloprostenol 17 days after MGA removal and were inseminated during induced estrus. In both groups, cows without estrus detection during the day stayed with a bull at night for possible mating. Pregnancy was diagnosed by ultrasound examination 40 days after AI. Chi-square analyses were used to detect differences between groups. Eight (38.1%) animals of group 1 and 7 (36.8%) of group 2 showed estrus after withdrawal of MGA (P>0.05). The conception rates in groups 1 and 2 were, respectively, 37.5% and 50.0% for inseminated cows and 58.3% and 64.3% for inseminated cows mated by the bull at night (P>0.05). These results suggest that it is possible to use the first estrus of females treated with ECP on day 5 of a 14-day MGA treatment. Furthermore, considering the large number of cows mated by the bull at night, it is recommended to use estrus detection tools as an aid for the identification of such animals or to combine AI and bulls for breeding.","PeriodicalId":43616,"journal":{"name":"BOLETIM DE INDUSTRIA ANIMAL","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2019-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46520508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
