“…Thus, water intake was lower through the drinking fountain for SSCF and BHCF (48.56% and 51.87%, respectively). This behavior confirms the report by Neto et al (2016) and Sousa et al (2018) that water is a limited supply in the semiarid and may be an obstacle to livestock production, however, when consuming succulent foods, water intake may be very low or zero. Succulent foods, characterized by high water concentrations and low dry matter content, for example, forages and preserves, such as silage, can be important sources of water for goats raised in the semiarid region (Gedir et al, 2016).…”

The objective of this study was to evaluate the use of sorghum silage, Buffel grass hay and forage palm fodder in the diet of dairy goats by means of performance tests and economic viability of different roughage sources. Eight Anglo-Nubian goats, multiparous, weighing around 40.13 ± 2.76 kg of live weight were used. The experiment lasted 84 days, consisting of four periods of 21 days, distributed in two Latin squares (4x4). The treatments represented by diets with different volumetric sources: SSCF: (sorghum silage+ forage palm+ concentrate); BHCF: (Buffel grass hay + cactus forage+ concentrate); SS: (sorghum silage+ concentrate) and BH: (Buffel grass hay + concentrate). Nutritional intake, digestibility, feed behavior, milk production and chemical composition and economic analysis were evaluated. Animals fed the BHCF diet had higher nutrient intakes and consequently were more productive in fat, protein, lactose, fat free solids and total solids. The BHCF diet led to a higher gross income in Brazilian currency. The safety margin of the SSCF diet presented the highest percentage, with 43.06%, and the BHCF diet, the lowest percentage, of 14.89. The association of forage palm with sorghum silage and Buffel grass hay can be used as a bulky source in lactating goat diets.

“…The rumination and idle time did not differ between different particle sizes and NDFf levels (Table 3). Differently, the increase in NDFf contents was significant on idle and rumination behavior for some authors (Branco et al, 2011;Sousa et al, 2018). According to Branco et al (2011) and Sousa et al (2018), increased NDFf contents caused no change in the feeding activity, but increased rumination, because this behavior is related in the processing of dietary fiber to pass through the digestive tract of ruminants.…”

However, we demonstrated that there was a selective behavior in the feeding activity, and this may have removed, among the treatments, the need to increase fiber processing through rumination when the NDFf content and the particle size is increased.…”

The purpose of this study was to evaluate the effect of interaction between increasing neutral detergent fiber content and particle sizes on ingestive behavior of dairy goats. Forty-eight lactating, multiparous Saanen and Alpine goats, with average milk production of 1.4 ±0.57 kg d -1 , around 60 th ±12 day of lactation were distributed in a 3 x 4 factorial completely randomized design. The diets consisted: three particles sizes (02, 05 or 15 cm) and four levels of neutral detergent fiber (34, 41, 49 or 57% NDFf) from forage (Tifton 85 hay). The ingestive behavior was monitored during 24 hours. A regression and a multivariate time series cluster analysis were performed. No interaction was found (p > 0.05) between treatments. Feeding time was different according to the particle size, having an increasing linear effect. Rumination and idle times were not affected (p > 0.05). The temporal feeding behavior was clustered into two groups according to the profile of particle size of the diet. Rumination peaks were randomly distributed with more intense activity before morning and afternoon meals. The increase in NDFf content in the diet did not change the ingestive behavior. The multivariate cluster analysis in a time series data is useful to interpret animal feeding behavior.

“…The recent study of Sousa et al [54] with forage palm was in regard to the considerable amount of this byproduct available in some areas and few alternative uses. Dairy goats of an unspecified breed at 30 DIM were fed diets with 42.1%, 35.0%, 29.1%, 23.6%, and 19.9% forage palm and bermudagrass hay at 16.0%, 24.4%, 31.6%, 38.3%, and 42.8%, respectively.…”

Recent advances in the feeding and nutrition of dairy goats

There have been recent advances concerning research of the feeding and nutrition of dairy goats in a wide array of areas. Ruminally emitted methane and supplementary feedstuffs to a lesser extent make appreciable contributions to the carbon footprint of dairy goats, with the former affected by type of production system and associated dietary characteristics. Unique behavior of goats necessitates careful consideration of the nature of confinement facilities to achieve optimal production by animals differing in social hierarchy. Physiological conditions such as nutritional needs and perhaps health status may influence diet selection by goats in both grazing and confinement settings. Some research suggests that low concentrations of protein and fat in milk of high-yielding dairy goat breeds could involve the type and nature of dietary ingredients as influencing end products of ruminal fermentation. With the relationship between milk urea nitrogen concentration and efficiency of dietary protein utilization, through future research the measure may be a useful tool for diet formulation as in dairy cattle. Effects of dietary inclusion of sources of fats and oils vary considerably depending on their nature, as is also true for byproduct feedstuffs and conventional ones being substituted for. Supplementation of dairy goats with sources of polyunsaturated fatty acids can affect oxidative stress and various feedstuffs influence antioxidant status; however, research addressing the significance of such changes under practical production settings would be beneficial.
