Use of high moisture corn silage replacing dry corn on intake, apparent digestibility, production and composition of milk of dairy goats

Abstract

-Twenty primiparous and multiparous Alpine breed goats at approximately 80 days of lactation were used in this experiment. The animals were housed individually in metal cages and distributed according to milk production in five 4 × 4 Latin squares. The experimental diets used in the experiment presented concentrate:forage ratio of 65:35. The treatments were characterized by increasing levels of 0, 33, 67 and 100% of high moisture corn silage (HMCS) replacing corn dry grain (CDG). Average intake of DM (1.62 kg/day, 3.90 % BW), CP (0.22 kg/day), NFC (0.76 kg/day) and TDN (1.29 kg/day) were not influenced by levels of HMCS. However, intake of NDF (0.53 kg/day) was significant for the different level of HMCS. Daily milk production and production of milk correct at 3.5% of fat, feed efficiency (MP/DMI), fat percentage, protein, lactose, total solids and milk urea nitrogen, with means of 1.86; 1.69; 1.11; 2.96; 2.85; 4.36; 10.96 and 17.1, respectively, were not influenced by the levels of HMCS. Percentage of non fat solids (8.00%) was affected by replacing levels of HMCS. The use of high moisture corn silage in the diet does not change milk production and it can be applied in total or partial substitution to dry corn grain in the feeding of milk goats.Key Words: dairy goats, dry matter intake, processed corn Utilização da silagem de grãos úmidos de milho em substituição ao milho seco no consumo, digestibilidade aparente, produção e composição do leite de cabras leiteiras RESUMO -Foram utilizadas 20 cabras da raça Alpina, primíparas e multíparas, com aproximadamente 80 dias em lactação, alojadas individualmente em gaiolas metálicas e distribuídas, de acordo com a produção de leite, em cinco quadrados latinos 4 × 4. As dietas experimentais utilizadas apresentaram relação concentrado:volumoso 65:35. Os tratamentos foram caracterizados por níveis crescentes 0, 33, 67 e 100% de silagem de grãos úmidos de milho (SGUM) em substituição ao grão seco de milho (GSM). As médias de consumo de MS (1,62 kg/dia, 3,90 %PV), proteína bruta (0,22 kg/dia), carboidratos não fibrosos (0,76 kg/dia) e nutrientes digestíveis totais (1,29 kg/dia) não foram influenciadas pelos níveis de SGUM. Entretanto, o consumo de FDN (0,53 kg/dia) foi significativo para os diferentes níveis de SGUM. A produção diária de leite e produção de leite corrigida a 3,5% de gordura (kg/dia), eficiência alimentar (PL/CMS), porcentagens de gordura, proteína, lactose, sólidos totais e nitrogênio ureico do leite, com médias de 1,86; 1,69; 1,11; 2,96; 2,85; 4,36; 10,96 e 17,1, respectivamente, não foram influenciados pelos níveis de SGUM. A porcentagem de extrato seco desengordurado (8.00%) foi afetada pelos níveis de substituição da SGUM. A utilização de silagem de grãos úmidos de milho na dieta não altera a produção de leite e pode aplicada em substituição parcial ou total ao grão seco de milho na alimentação de cabras leiteiras.Palavras-chave: cabras leiteiras, consumo de matéria seca, milho processado Revista Brasileira de Zootecnia

Yeast and bacteria from ensiled high moisture maize grains as potential mitigation agents of fumonisin B1

“…High moisture maize grain (HMMG) silage is based on the natural fermentation of whole or ground grains that are harvested shortly after the physiological maturity stage with an optimum dry matter content around 70% . During the last decade, it has become a more ubiquitous practice in Europe since it can be easily processed on farms, represents an economic storage procedure (no grain drying costs are encountered) and leads to an interesting feed characterised by a high starch digestibility and nutritional value for livestock . To our knowledge, the fate of FB 1 during the HMMG ensiling process has not been documented while numerous studies have addressed the issue of whole maize plant silage contamination with mycotoxins .…”

The effect of a chemical additive on the fermentation and aerobic stability of high-moisture corn

“…High-moisture corn (HMC) is commonly fed to animals throughout the world (Buchanan-Smith et al, 2003;Szasz et al, 2007;Canizares et al, 2011). However, this ensiled feedstuff often has a high number of epiphytic yeasts (3-5 log cfu/g, Pahlow et al, 2003) and its aerobic stability can be very poor, especially when ambient temperatures are warm (Taylor and Kung, 2002;Kung et al, 2004).…”

Evaluation of rehydrated corn grain silage with okara or soybean inclusion in the performance of lactating cows

“…The decreased intake and increased digestibility show superior feeding efficiency for treatments with the inclusion of silages. The results of studies in the literature have indicated that grain silage is more efficient due to the better use of nutrients in the total diet (Canizares et al, 2011;Panichi et al, 2012).…”

“…Processing as corn grain silage acts positively on the digestibility of starch granules, as it leads to the breakdown of the protein matrix that involves the starch granules (Hoffman et al, 2011). In the feeding of dairy cows, some studies have not reported a difference in milk production and composition, but overall, grain silage is more efficient due to better use of nutrients in the total diet (Canizares et al, 2011;Panichi et al, 2012).…”
