“…EFFECT OF FEED PROCESSING ON THE PRODUCTIVE PERFORMANCE OF NILE TILAPIA Some authors report that protein levels above 24 or 26% always satisfy the growth requirements for juvenile tilapia. 20,21 Likewise, El-Wahab et al 22 suggested that diets with a protein content of around 34% are acceptable for tilapia farming. This result could be due to the content of amino acids present in the treatments since the amino acids required to improve tilapia performance are lysine, arginine, phenylalanine, isoleucine, leucine, methionine, threonine, and valine or a mixture of methionine, cystine, valine, and lysine.…”

The present study was to substitute fishmeal with domestic cricket (Acheta domesticus) meals in diets for tilapia (Oreochromis niloticus) farming. Productive performance was evaluated by two diets based on Pearson’s square, the treatment T1 with 20% inclusion and treatment T2 with 35%, respectively, and a control T3 (commercial feed) performed in triplicate. Each treatment had ten organisms weighing 9+5 gr for 40 days. Initial biometry was performed, and after this, every five days until the end of the bioassay. The production and survival variables were evaluated; Finally, a proximal analysis of moisture, ash, lipids, and protein was carried out. According to the weight gain, the performance of the diets presented significant differences between the three diets. T2 diet results were similar to T3 (Control) due to tilapia being omnivorous and having excellent resistance and adaptability to different types of food. Therefore, the possible use of this food can be considered, favoring its economic impact on tilapia crops.

“…Nitrogen was measured in a high temperature elemental analyzer (Vario Max®, Elementar, Hanau, Germany). The calcium content was determined by atomic absorption spectrometry, phosphorus colorimetrically [ 33 , 34 ]. For the analysis of crude fiber the fat- and ash-free samples were cooked with acid (1.25% sulphuric acid) and alkaline (1.25% sodium hydroxide) solutions in a crude fibre determination device (Fibertec™ 2010 Hot Extractor, Fa.…”

Background Multiple diagnostic procedures, their results and interpretation in a case with severe lameness in fattening pigs are described. It is shown that selected diagnostic steps lead to identification of various risk factors for disease development in the affected herd. One focus of this case report is the prioritization of diagnostic steps to verify the impact of the different conditions, which finally led to the clinical disorder. Assessing a sufficient dietary phosphorus (P) supply and its impact on disease development proved most difficult. The diagnostic approach based on estimated calculation of phosphorus intake is presented in detail. Case presentation On a farrow-to-finishing farm, lameness occurred in pigs with 30–70 kg body weight. Necropsy of three diseased pigs revealed claw lesions and alterations at the knee and elbow joints. Histologic findings were characteristic of osteochondrosis. All pigs were positively tested for Mycoplasma hyosynoviae in affected joints. P values in blood did not indicate a P deficiency, while bone ashing in one of three animals resulted in a level indicating an insufficient mineral supply. Analysis of diet composition revealed a low phosphorus content in two diets, which might have led to a marginal P supply in individuals with high average daily gains with respect to development of bone mass and connective tissue prior to presentation of affected animals. Finally, the impact of dietary factors for disease development could not be evidenced in all submitted animals in this case. Conclusions Mycoplasma (M.) hyosynoviae was identified to be an important etiologic factor for disease. Other, non-infectious factors, such as osteochondrosis and claw lesions might have favored development of lameness. In addition, a relevant marginal P supply for pigs was found in a limited time period in a phase of intense growing, but the potential interaction with infection by M. hyosynoviae is unknown. The presented case of severe lameness in fattening pigs revealed that three different influences presumably act in pathogenesis. Focusing only on one factor and ignoring others might be misleading regarding subsequent decision-making for prevention and therapy. Finally, clinical symptoms disappeared after some changes in diet composition and anti-inflammatory treatment of individual animals.
