Nutrient intake, feeding patterns, and abnormal behavior of growing bulls fed different concentrate levels and a single fiber source (corn stover silage)

Abstract The objective of the study was to evaluate the effect of corn stover silages with two sources of energy (cane molasses or milk whey) and EM (effective microorganisms, 1 mL/kg DM) on the digestibility of nutrients and rumen fermentation. We hypothesized that inoculation with EM (lactobacillus spp and Rhodopseudomona palustris and Saccharomyces cerevisiae) in the silage process of corn stover coud improve the in vivo digestibility and ruminal fermentation in sheep. Six male sheep with cannula in the rumen were used in a 6 x 6 Latin square design. Experimental periods consisted of 11 d for diet adjustment followed by 5 d for collection. The animals were housed in metabolic cages, with a harness to collect faeces individually. Diets consisted of concentrate (corn grain, soybean meal, mineral salt) 55% and corn stover 45% dry basis. The treatments were: CS-AMW= Corn stover with acid milk whey, CS-CM= corn stover with sugar cane molasses, SIL-AMW= corn stover silage with acid milk whey, SIL-CM= corn stover silage with cane molasses, SIL-AMW-EM= corn stover silage with acid milk whey and EMand SIL-CM-EM= Corn stover silage with cane molasses and EM. The results were analyzed with PROC MIXED procedures of SAS. The inoculation of corn stover with EM increased (P < 0.05) the content of CP in SIL-AMW-EM and SIL-CM-EM respect CS-CM (Table 1). SIL-CM-EM increase (P < 0.05) the ruminal N-NH3 and pH (Table 2) but no effect was observed for digestibility (Table 3). However, the SIL-AMW improved (5.8%, P < 0.05) the OM digestion compared with CS-AMW. A diet with 45% corn stover silage with EM was not sufficient to improve in vivo digestibility of nutrients in sheep. This project was supported by UNAM,DGAPA, PAPIIT (IT202120)

Background: Toddlers are a group that is vulnerable to experiencing nutritional problems. The nutritional status of toddlers is very dependent on the role of caregivers, especially mothers. Business women have less time together with toddlers so that it will have an impact on mothers' attention to the growth and development of toddlers, child feeding patterns, food diversity, and macro-nutrient intake of toddlers. Research in Padang states that business women have a 1,3 times risk of experiencing malnutrition in children. Purpose: Know the differences in child feeding patterns, food diversity, and macro nutrient intake in toddlers from business women and housewife. Method: The design of this study was an observational analytic with cross sectional approach. The research was conducted on medium socioeconomic housing in Banyumas Regency. The sample are toddlers aged 12-59 months as many as 78 toddlers, taken using total sampling techniques. Data were statistically tested using independent T tests. Results: The results of study showed no differences in child feeding patterns (p = 0.605), food diversity (p = 0.767), energy intake (p = 0.483), protein intake (p = 0.806), fat intake (p = 0.787) and carbohydrate intake (p = 0.337) in toddlers from business women and housewife. Conclusions: There were no differences in child feeding patterns, food diversity, and macro nutrient intake in toddlers from business women and housewife.

Over Time

Analyses of rats' feeding behavior at the start and the end of the nocturnal cycle have revealed dramatic alterations in macronutrient intake over time. At dark onset, rats displayed a preference for carbohydrate, with the first meal of the night consisting of approximately 60% of this nutrient. This carbohydrate intake was soon followed by a shift toward protein-predominant meals. Superimposed on this pattern of meal-to-meal shifts in nutrient selection appears to be an additional rhythm in which carbohydrate ingestion was favored at dark onset and protein and fat ingestion were favored during the late dark hours. Differential feeding patterns were also apparent following mild food deprivation. A 2-h period of deprivation at dark onset produced a strong compensatory feeding response, particularly of fat and carbohydrate. This pattern was not observed at the end of the dark, when little compensatory feeding was demonstrated. It is suggested that these feeding patterns may be related to the activity of certain hypothalamic neurotransmitters, e.g., norepinephrine and serotonin, known to be important in modulating temporal feeding patterns and nutrient intake.

Farm System

Two trials were conducted to investigate the effect of NaOH on the ensiling characteristics of corn and alfalfa forage. In one trial, NaOH was added at levels of 0, 2, 3, or 4% of dry matter (DM) to whole plant corn and 0 or 3% to corn stover, and ensiled in cryovac bags. In a second trial, 0 or 3% NaOH was added to whole plant corn or alfalfa (25–40% DM). In addition, alfalfa had molasses added at a level of 0 or 10% of the forage DM. Materials were ensiled in miniature silos of 250-ml capacity. Additions of NaOH to all forages increased silage pH (P < 0.05). Molasses may have some influence in limiting the rise in pH after addition of NaOH but the effect appears to be limited. Alkali treatment of corn stover silage and corn silage generally increased lactic acid production. Total-N of all silages tended to decrease with NaOH treatment. However, alkali treatment markedly reduced soluble-N with all forages (P < 0.05), except with corn stover. Molasses also reduced soluble-N (P < 0.05) with alfalfa silage of low DM content. Treating forages while ensiling would appear to represent a suitable on-farm system for alkali treatment.
