“…Silage can provide up to 9% Ca, 34% K, 23% Mg, 12% P, and 15% S of respective daily needs for dairy cattle consuming 26 kg dry matter per day composed of 40% (10.4 kg DM) corn silage. For trace elements, the average corn silage can provide up to 13% Cu, 847% Fe, 80% Mn, and 11% Zn from daily intake requirements [ 110 ].…”

Lameness is currently one of the most important and economically demanding diseases in cattle. It is manifested in a change in locomotion that is associated with lesions, especially the pelvic limbs. The disease of the hoof is painful, affecting the welfare of dairy cows. Important factors that influence the health of the limbs include nutrition, animal hygiene, stable technology, and genetic and breeding predispositions. Nutrition is one of the basic preventive factors affecting the quality and growth of the hoof horn, and the associated prevalence of hoof disease. The strength and structure of the hoof horn are affected by the composition of the feed ration (amino acids, minerals, vitamins, and toxic substances contaminating the feed ration, or arising in the feed ration as metabolites of fungi).

“…In an exploratory study with 165 horses, a negative correlation was found between Zn and tensile strength [ 29 ], and the same was observed in the present study, where a relationship with a coefficient of −0.10 was obtained, and similar results were previously presented in a study on donkey hoof samples, although this was reported as hoof strength [ 30 ]. Ley did not find an association between Zn and tensile strength [ 11 ], and these findings have to be considered when feeding horses, since zinc is usually supplemented to increase the strength or quality of horse hooves. The same scenario was presented for Na, with a coefficient of −0.003, and for this reason, it is important to pay attention to the diets that are administered to horses, since an imbalance can cause abnormalities in growth and development which predispose the hoof to microfractures [ 29 , 31 ].…”

“…An additional key factor is the maturity of the forage at the time of harvest [ 9 ]. Other reasons for its exclusion from diets are that its acidity is thought to adversely impact health in addition to its hygienic quality being questionable; for this reason, it is recommended that the nutritional quality of silage be characterized by sending a representative sample to the laboratory, in addition to analyzing for the possible presence of pathogenic bacteria, fungi, and mycotoxins [ 10 , 11 ].…”

The type of diet that a horse consumes is one of the most important factors determining the mineral profile and tensile strength of its hooves, so the quality and nutritional value of the supplied feed are fundamental to achieving satisfactory hoof quality. The objective of this study was to compare the differences in the mineral concentrations of sodium (Na), potassium (K), magnesium (Mg), zinc (Zn), and Iron (Fe) between two diets, namely silage and a commercial concentrate, using atomic absorption spectrometry and to determine which led to higher increases in the hoof tensile strength of horses consuming these diets. Thirty-two Spanish horses were randomly divided into two groups, where the diet of the horses in group 1 was silage oat hay, and that of the horses in group 2 was a commercial concentrate and oat hay. Both diets were provided for 12 months. The hoof tensile strength was then measured using an Instron universal testing machine. Mg and Fe levels were higher (p < 0.05) in the silage than in the commercial concentrate, and hoof Mg, Zn, K, and tensile strength were also influenced by the hormonal stage (p < 0.05). The type of diet directly affected the hoof Mg, Zn, K, Na, and tensile strength (p < 0.05), which Mg, K and Na were higher in horses fed with concentrate. It was found that for each unit of Zn (μg/g and Na (μg/g),) in the hoof, the tensile strength is affected by −0.10 N/mm2 and −0.003 N/mm2, respectively for each mineral.

Fungal spoilage and mycotoxin contamination are two of the greatest hazards of silage. The present work was carried out to evaluate the impact of Lactobacillus bulgaricus and cellulolytic enzymes on the maize silage (MS) quality. Fungal analysis of different MS samples showed different mycotoxigenic fungi. The highest frequency (62.8%) was associated with Fusarium spp. Four species with different relative densities were found: F. graminearum (71.1%), F. culmorum (15.2%), F. proliferatum (11.2%), and F. oxysporum (2.50 %). High-performance liquid chromatography analysis showed the presence of trichothecene, nivalenol, zearalenone, and fumonisins mycotoxins in MS inoculated by F. graminearum. The inhibition % of trichothecene, nivalenol, and zearalenone synthesis was 50.2%, 47.5%, and 23.5%, respectively, in MS inoculated by Lactobacillus bulgaricus after a 30 d incubation period. Trichoderma harzianum succeeded in producing cellulolytic enzymes, i.e., carboxymethyl cellulase, manganase peroxidase, and laccase, with a maximum production of 350 µg/mL, 5.47 µg/mL, and 16.0 µg/mL, respectively, after 21 d using MS as the substrate. Treatment by the extracted cellulolytic enzyme with L. bulgaricus enhanced unfavorable conditions for MS fungal contamination, i.e., the production of lactic acid, a lowered pH, and increased L. bulgaricus colony-forming units, compared to the addition of enzyme extract or L. bulgaricus alone.
