Vegetable by-products have great potential for use as animal feeds and thus could improve the sustainability of the food system. The objective was to evaluate the milk production potential of potato by-product (PBP) replacing cereal grains in grass silage-based total mixed ration (TMR). Additionally, a laboratory scale experiment was conducted to assess the effect of PBP and chemical preservatives on the aerobic stability of TMRs. A change-over dairy cow feeding experiment was conducted to evaluate the inclusion of 135 g/kg (on a dry matter (DM) basis) of PBP in TMR. Additionally, the aerobic stability of TMR was evaluated by preparing TMRs with increasing levels of PBP and treated with different doses of formic and propionic acid or salt-based preservatives. The inclusion of PBP in dairy cow diets decreased feed intake, but organic matter digestibility was greater in the PBP diet, resulting in only slightly decreased production (milk protein 1435 vs. 1363 g/day, p < 0.05; milk lactose 1716 vs. 1606 g/day, p < 0.05). The aerobic stability of TMR was negatively affected by the inclusion of PBP, but it could to a limited extent be prolonged using chemical preservatives. The inclusion of PBP decreased feed intake and milk production to some extent when included in the diet of high-producing dairy cows. The utilization of PBP may, however, be justified from a sustainability point of view, as it provides a way to circulate the nutrients of a non-human edible feed material back into the food chain.

The integration of feeding behaviour with hepatic and endocrine–metabolic signals provides insights for a better understanding of short-term intake in dairy pasture-based systems. Therefore, the objective was to quantify hepatic and endocrine–metabolic signals before and after the first daily feeding event relating to feeding behaviour in a total mixed ration (TMR) versus a grazing pasture-based diet. During 15 days of adaptation and 5 days of measurements, 14 multiparous Holstein cows (days in milk = 148 ± 12.7; liveweight = 535 ± 10.9 kg; body condition score = 2.8 ± 0.08 (1–5 scale); milk yield = 28.9 ± 3.32 kg) were assigned to two treatments in a randomised block design: PAS = pasture (herbage allowance = 45 kgDM/cow.day; dry matter (DM) = 21%, net energy requirements for maintenance and lactation = 6.7 MJ/kgDM) + concentrate (0.9% of liveweight) or TMR (55:45 forage:concentrate ratio, as-dry basis; DM = 40%, net energy requirements for maintenance and lactation = 7.2 MJ/kgDM) ad libitum in a free stall facility. The DM intake of the first feeding event, feeding behaviour, and total DM intake and milk production, were measured. Blood and liver samples were taken before and after the first feeding event for hormones and metabolites determination. Comparing TMR versus PAS cows, total DM and net energy requirements for maintenance and lactation intake, milk production, and energy balance were greater (P &lt; 0.05), eating and rumination activities were lower (9.2%, P &lt; 0.01; 2.4%, P = 0.06 respectively) and resting activity was greater (11.6%, P &lt; 0.01), whereas duration and DM intake of the first feeding event did not differ. The insulin:glucagon ratio and liver adenosine triphosphate:adenosine diphosphate ratio increased (P &lt; 0.05), and plasma glucose decreased (P &lt; 0.05) after the first feeding event only in TMR cows, probably due to greater flux of propionate to the liver. A negative correlation between post-feeding liver adenosine triphosphate:adenosine diphosphate ratio and post-feeding liver acetyl coenzyme A (r = –0.82, P = 0.045) was also observed only in TMR cows. It is concluded that hepatic and metabolic signals known to support the hepatic oxidation theory in TMR-fed cows appear not to affect the cessation of the first feeding event in mid-lactation cows grazing a pasture-based diet. Further research is required to relate intake rate, flux of nutrients to liver and its response in hepatic metabolism in grazing dairy cows.

This study compared the effects of a short daily grazing time with those of permanent free-stall housing on the behaviour, oxidative status, immune response, and milk production of organically reared cows. During a 63-day period, two homogeneous groups of eight lactating Brown cows were allocated to either housing (H) in a free-stall building for 24 h/day. Feeding was based on a total mixed ration or grazing (G) on barley grass for 5 h/day, and housing in a free-stall structure with feeding was based on the same total mixed ration offered to the H group. With regard to behaviour, H cows spent more time idling, walking, drinking, and self-grooming, whereas G cows showed a greater intent to eat and interact socially. Moreover, G cows exhibited slightly higher reactive oxygen metabolites and similar biological antioxidant potential concentrations than the H group, which indicates that short grazing resulted in an almost negligible increase in oxidative stress and an unchanged antioxidant capacity. Skin tests, performed by injecting phytohemoagglutinin intradermally, indicated that G cows had thicker skin than H cows at the end of the trial, an index of a better cell-mediated immune response. Grazing did not affect milk yield but improved milk quality in terms of an increase in fat and a reduction in urea content, somatic cell count, and total microbial count. Milk from G cows was richer in saturated fatty acids, likely because of the contribution of palmitic acid present in the grazed barley grass, and also showed higher contents of some healthy fatty acids, such as rumenic acid and α-linolenic acid, and a lower omega-6/omega-3 ratio. These results show that including a short grazing time in the diets of organic dairy cows does not have negative consequences for milk production and contributes to improved milk quality as well as to a more efficient immune response in the cows.
