“…Therefore, the CGP and CG treatments had the same composition, with the heat treatment as the only difference between them. A reduction in EE intake in the total diet was also observed by dos Santos et al (2011) that worked wich ground sunflower seeds in a pelleted vs non-pelleted concentrate treated with or without lignosulfonate.…”

“…The processing of concentrated feeds via thermal treatments, as the pelleting, is an alternative method to protect canola PUFA from ruminal biohydrogenation, and to improve nutrient digestibility of the diet ( Neves et al, 2007 ; Neves et al, 2009 ; dos Santos et al, 2011 ). Another alternative is the use of ionophores that, in addition to improving energy metabolism, reducing the ruminal degradation of dietary protein, increasing the digestibility and milk production, also reduce SFA and increase CLA content in the milk of dairy cows ( Duffield et al, 2008 ; da Silva-Kazama et al, 2011 ).…”

To evaluate the effects of the pelleting and the addition of sodium monensin on production, the chemical and lipid composition of milk and butter physical characteristics, 4 Holstein dairy cows (135 days of lactation) with an average milk production of 14.7 kg/d, were supplemented with a concentrate containing ground canola seeds. The cows were assigned to a 4×4 Latin square design with a 2×2 factorial arrangement of treatments: i) ground maize, soybean meal, mineral and vitamin supplements, and ground canola seeds (CG); ii) CG concentrate with 31.5 mg of monensin added per kg of dry matter (DM); iii) CG pelleted concentrate; iv) CG concentrate with monensin addition pelleted. There was no difference in milk production and composition. The addition of monensin increased milk concentration of polyunsaturated fatty acids (PUFA), the PUFA/saturated fatty acids (SFA) ratio, and omega 6. The pelleting increased the concentration of monounsaturated fatty acids, the PUFA/SFA ratio, and the omega 6/omega 3 ratio, but decreased the concentration of SFA. The association between pelleting and the addition of monensin increased the concentration of conjugated linoleic acids by 46.9%. The physical characteristics of butter were not affected by the evaluated diets. We concluded that the concentrate with 31.5 mg of monensin added per kg DM basis combined with the pelleting improves the lipid composition of milk from Holstein cows that are on pasture and supplemented with ground canola seeds, without changing the production, milk composition, and spreadability of butter.

“…In a beef cattle production system, the reproductive performance of females is essential for maximum profitability (Santos et al, 2011). Beretta, Lobato & Mielitz Netto (2001) reported that the birth rate of breeding animals is the variable that causes the greatest impact on profitability within a production system.…”

We analyzed the pregnancy rate (PR) and birth rate (BR) of Nellore cows raised extensively in the Cerrado/Pantanal during 4 mating seasons (2009)(2010)(2011)(2012), assessing the relationship with the temperature and humidity index (THI) and the effect of the year and breeding season. We used information from 2,116 cows, which were categorized as either multiparous (n = 1430), primiparous (n = 338), or nulliparous (n = 348). In the months of the breeding season (December-February), temperature and relative humidity data were collected to calculate the temperature and humidity index (THI). An ANOVA was performed with a model that included sources of variation from the fixed effects of category of cow and year on PR and BR; and a linear regression analysis and correlation between THI and PR and BR. We observed a significant effect (p < 0.05) on PR. We classified the average across breeding seasons as a moderate THI. The THI of the breeding seasons showed high and significant (p < 0.05) effects only on the nulliparous BR, and low values in other categories. It is concluded that the seasonal THI was not related to the performance of cows, except BR in nulliparous cows.Keywords: beef cattle, environmental effect, reproductive efficiency.Interação do ambiente com desempenho reprodutivo de matrizes Nelores criadas extensivamente no ecótono Cerrado/Pantanal RESUMO. Analisou-se taxa de prenhez (TP) e de natalidade (TN) de matrizes Nelores criadas extensivamente no Cerrado/Pantanal, acasaladas durante 4 estações de monta natural (2009 a 2012), avaliando relação com índice de temperatura e umidade (ITU) e efeito do ano da estação de monta. Utilizaram-se 2.116 informações de matrizes, pertencentes às categorias de multíparas (n = 1430), primíparas (n = 338) e nulíparas (n = 348). Nos meses de estação de monta (dezembro a fevereiro) coletaram-se informações da temperatura e umidade relativa do ar, para o cálculo de índice de temperatura e umidade (ITU). Realizaram-se análise de variância com um modelo contendo como fontes de variação os efeitos fixos de categoria e ano de estação de monta sob a TP e TN; e análise da regressão linear e correlação entre o ITU e a TP e TN. Observaram-se efeito significativo (p < 0,05) de categoria sob a TP. Classificou-se o ITU médio entre as estações de monta como moderado. O ITU das estações de monta apresentou relação alta e significativa (p < 0,05) apenas na TN das nulíparas, e baixas tendências de relação com as demais. Conclui-se que o ano da estação de monta e o ITU não apresentaram relação com desempenho das matrizes, exceto as nulíparas considerando ITU e TN.

This study evaluated the effects of feeding ground (G) versus pelleted (P) total mixed ration (PTMR) on digestibility and milk production performance of mid-lactation dairy cows over a 42-days period. Results showed that, compared to GTMR, feeding PTMR increased dry matter intake and digestibility, ruminal propionate proportions and milk protein percentage, but decreased acetate-topropionate ratio, milk fat percentage and aldehydes, acids, alcohols, and aromatic hydrocarbon proportions in milk. The PTMR did not improve milk yield but accelerated live weight recovery of cows and led to acidosis risk in lactating cows due to negative effects on rumen fermentation.
