“…Total dry matter intake consumed outside of distinct meals was minimal (less than 1%). These criteria are similar to those used by Wangsness et al (1976) for sheep. They defined a meal as at least 1 min of eating activity occurring after at least 20 min without eating activity.…”

“…Meal size was also positively related to eating rate, but the relationship was curvilinear. Wangsness et al (1976) also showed that eating rate increased with meal size, and that for larger meals, eating rate reached a plateau while meal duration continued to increase.…”

“…Prolonged duration of meals allowed cows to consume more feed during the meal, which eventually led to higher daily DMI. Wangsness et al (1976), working with sheep fed a complete ration composed of 20% chopped hay and 80% concentrate, reported a positive relationship between meal size and meal duration (r = 0.49). In contrast to our observations, a negative correlation between meal duration and the number of meals was reported previously for dairy cows fed TMR (Vasilatos and Wangsness 1980).…”

. 2002. Effect of diet and parity on meal patterns of lactating dairy cows. Can J. Anim. Sci. 82: 215-223. Four multiparous and four primiparous lactating dairy cows housed in stalls were used in a double 4 × 4 Latin square to determine the effect of parity and diet on meal patterns. Cows were fed one of four diets: three total mixed rations containing 40, 50, or 60% barley silage on a dry matter (DM) basis, and a diet in which forage and concentrate were allocated separately (SI) containing 50% concentrate. Dry matter intake was similar for all diets (18.2 ± 0.6 kg d -1 ), as were the number of meals per day (10 ± 1 meals d -1 ) and meal duration (35 ± 3 min meal -1 ). Meal size was larger (5.2 vs. 1.1 or 1.9 kg DM meal -1 ), and eating rate was faster (0.265 vs. 0.053 or 0.034 kg DM min -1 ) when cows consumed concentrate, compared with silage or TMR, respectively. Meal size of TMR, silage or concentrate was positively related to DM intake (r = 0.82, 0.76, and 0.98; respectively). For cows consuming TMR, the number of meals per day was negatively related to DM intake (r = -0.41). Dry matter intake increased when meal size increased, primarily as a result of longer meals and, to a lesser extent, faster eating rate. Feeding management had little effect on meal patterns. Multiparous cows tended to eat more in each meal compared with primiparous cows, but both groups spent the same amount of time eating per meal. . La prise de matière sèche était identique dans tous les cas (18,2 ± 0,6 kg par jour), comme le nombre de repas par jour (10 ± 1) et la durée du repas (35 ± 3 minutes par repas). Les portions étaient plus importantes (5,2 c. 1,1 ou 1,9 kg MS par repas) et la consommation plus rapide (0,265 c. 0,053 ou 0,034 kg MS par minute) chez les vaches nourries de concentré que chez celles recevant de l'ensilage ou une RTM, respectivement. On a établi une corrélation positive entre la grosseur de la portion de RTM, d'ensilage ou de concentré et l'absorption de MS (r = 0,82, 0,76 et 0,98, respectivement). Chez les vaches nourries de RTM, on remarque une corrélation négative entre le nombre quotidien de repas et l'absorption de MS (r = -0,41). La prise de matière sèche augmente avec la grosseur de la portion, principalement parce que le repas dure plus longtemps et, dans une moindre mesure, parce que les animaux mangent plus vite. La gestion du régime n'a pas une grande incidence sur les habitudes alimentaires. Les vaches multipares ont tendance (P = 0,17) à consommer plus que les vaches primipares à chaque repas, mais les deux groupes passent autant de temps à manger.

“…A meal was defined as at least one observation of feeding activity occurring after at least 20 min without feeding activity. This is based on the definition of feeding used by Wangsness et al (1976), who defined a meal as at least 1 min of eating activity after at least 20 min without eating activity. A period of rumination was defined as at least 5 min of rumination occurring after at least 5 min without ruminating activity.…”

Replacement of wheat bran with spineless cactus in sugarcane-based diets for steers

-The effect of replacing wheat bran with spineless cactus (0, 25, 50, 75, and 100%) in sugar cane-based diets on the intake of nutrients, feeding behavior, and rumen digestibility of steers was assessed using digested samples collected from the omasum. Five crossbred steers (½ Holstein-Zebu) were fitted with cannulas in the rumen and then assigned to a 5 × 5 Latin square design. Samples of omasal digesta were collected for three days. Rumen was evacuated via the rumen cannula to determine the rumen pool of dry matter (DM), neutral detergent fiber (NDF), indigestible NDF (iNDF), intake (ki), passage (kp) and degradation (NDF) rates, and the passage of iNDF (kpi). Nutrient intake displayed a quadratic effect, with maximum intakes of DM (5.73 kg d −1 ), non-fiber carbohydrates (NFC, 4.63 kg d −1 ), and digestible organic matter (DOM, 3.45 kg d −1 ) estimated at the replacement levels of 54.63, 60.00, and 43.17%, respectively. The replacement levels showed no effect on feeding, rumination, or idle times. There was a linear increase in the total apparent and ruminal digestibility of CP as the spineless cactus content in the diet was increased. There was no effect on total and partial digestibilities of OM and NDF or on intestinal digestibility of CP. No effect was observed on the rumen pool of DM, NDF, or iNDF. Furthermore, ki, kp, NDF degradation, and iNDF passage rates displayed a quadratic effect, with higher concentrations estimated for replacement levels of 56.07, 56.12, 59.00, and 55.20%, respectively. Replacing 55% wheat bran with spineless cactus in sugar cane-based diets is recommended.

In times of drought, the availability of feed is reduced, and the use of concentrate ingredients, such as wheat bran, becomes costly for animal production. Thus, the use of spineless cactus emerges as a potential solution to the shortage of feed and water during prolonged drought periods. The objective of this study was to evaluate the effects of replacing wheat bran with spineless cactus plus urea (0%, 25%, 50%, 75%, and 100%) in sugarcane-based diets for sheep on nutrient intake, feeding behaviour, nitrogen balance and microbial protein synthesis. Five male Santa Ines sheep with average initial bodyweight of 34.0 ± 3.6 kg were used in a 5 × 5 Latin square. The maximum intakes of dry matter (DM) (1414 g/day), organic matter (OM) (1281 g/day), crude protein (CP) (204 g/day), neutral detergent fibre corrected for ash and protein (NDFap) (425 g/day), and total digestible nutrients (TDN) (890 g/day) were estimated with replacement levels of 80.2%, 75.3%, 88.6%, 50.5%, and 79.3% respectively. Feeding behaviour was not altered by replacing wheat bran with spineless cactus plus urea. Nitrogen retention increased by 0.10 g/day, while plasmatic urea nitrogen increased by 0.20 mg/day for every 1% level of replacement. The maximum production of microbial nitrogen (15.9 g/day) and microbial protein synthesis (99.4 g/day) were estimated with replacement levels of 45.8 and 45.7%, respectively. It is concluded that up to 80% wheat bran could be replaced with spineless cactus plus urea in sugarcane-based diets for sheep. ______________________________________________________________________________________
