“…Extensive meat goats are fed on forages, increasing the profit to the producers; pasture based production systems are limited, however, because of seasonal variations in nutrient content of the pasture forage. This often means that the pasture by itself does not provide adequate nutrition for quickly growing animals (Wilkinson & Stark, 1987). In intensive with artificial or natural rearing systems, an additional protein and energy source (hay or concentrate) is offered to maintain acceptable goat performance.…”

-The aim of this research was to study the effects of three different management systems on growth and carcass quality of 61 Murciano-Granadina breed kids and their interaction with sex. In the extensive system, 21 kids were allocated to suckle from their dams on free-range pasture with no additional feedstuff. In the semi-intensive system, 20 kids were suckled from their dams and had access to alfalfa hay and cereal straw (no free-range pasture). In the intensive system, 20 kids were separated from the dams at birth and then fed with milk replacer and alfalfa hay. Animals were slaughtered at 7.00 ± 1.00 kg of average BW. The semi-intensive system and extensive system kids grew faster than intensive system animals (127, 113 and 96 g/d, respectively). Differences in energy intake may explain these differences. Intensive system kids displayed the lowest real dressing percentages, calculated as 100 × (hot carcass weight/empty body weight), due to high development of empty gastrointestinal tract. The long leg and carcass were larger in extensive system kids than in kids from other management systems, presumably due to high physical activity on the free-range pastures. The carcasses and cuts from semi-intensive system and extensive system kids displayed more fat than those of intensive system kids. Males grew faster than females (122 and 103 g/d, respectively). Carcasses in male kids showed a higher content of bones but a lower content of fat than carcasses in female kids. The extensive system is feasible for producing kid meat from a dairy breed.

“…On the other hand, average dry matter intake in relation to body weight (3.87%) was within the range recommended by AFRC (1998), NRC (1981) and indicated by Wilkinson & Stark (1987), who cited that dry matter intake of goats is usually around 3 and 5 % of body weight. In Alpine goats fed different levels of NDF and CP, Carvalho et al (2006) and Fonseca et al (2006) observed dry matter intakes of 4.60 and 4.21% of body weight, respectively, values higher than those found in this experiment.…”

-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
