The Impact

Abstract Recent studies have shown that feed intake, nutrient metabolism and utilization may vary during the 24-h circadian period. In this regard, this study aimed at evaluating the impact on performance from the switching of conventional to sequential feeding programs with diets that differ in amino acid content over the day for growing–finishing pigs. Sixty-eight 25-kg (±2.04) BW barrows were assigned to 4 feeding programs (17 animals per treatment): 1) conventional feeding (CONV), in which pigs received 100% of standardized ileal digestible (SID) AA recommendations for the entire day; 2) sequential feeding (SEQ80-120), providing 80% SID AA recommendations from 2400 to 1159 h and 120% from 1200 to 2359 h; 3) sequential feeding (SEQ70-130) providing 70% SID AA recommendations from 2400 to 1159 h and 130% from 1200 to 2359 h; and 4) sequential feeding (SEQ60-140) providing 60% SID AA recommendations from 2400 to 1159 h and 140% from 1200 to 2359 h. The experimental period lasted 82 d and was subdivided in 3 phases: phase 1 (0 to 28 d), phase 2 (29 to 54 d) and phase 3 (55 to 82 d). The data were analyzed using the MIXED procedure in SAS (SAS Inst. Inc., Cary, NC). SEQ80-120 and SEQ60-140 did not improve performance compared to CONV (P > 0.05). However, ADFI, ADG and BW was higher for SEQ70-130 than CONV during phase 1 (1.49 vs 1.3 kg/d; 0.74 vs 0.65 kg/d; 46.55 vs 43.40 kg, respectively; P < 0.05). During phase 2, BW tended to be higher for SEQ70-130 than CONV (69.20 vs 63.60 kg; P = 0.08). In the entire experimental period, ADFI tended to be higher for SEQ70-130 than CONV (2.08 vs 1.89 kg/d; P = 0.10). According to our results, sequential feeding program improves performance of growing–finishing at the beginning of the period.

Abstract This study evaluated the effect of conventional and sequential feeding programs with diets varying in amino acid content over the day on nutrient balance for growing-finishing pig. Sixty-eight barrows with an average initial BW of 25.0±2.04 were housed in a single pen with five automatic intelligent precision feeders (AIPF; University of Lleida, Lleida, Spain). Pigs were distributed in four feeding programs: 1) conventional feeding (CONV) in which pigs received 100% of SID AA recommendations for the entire day; 2) sequential feeding (SEQ80-120) providing 80% SID AA recommendations from 0000 to 1159h and 120% from 1200 to 2359h; 3) sequential feeding (SEQ70-130) providing 70% SID AA recommendations from 0000 to 1159h and 130% from 1200 to 2359h; and 4) sequential feeding (SEQ60-140) providing 60% SID AA recommendations from 0000 to 1159h and 140% from 1200 to 2359h. Body lean mass and mineral body content were obtained by DXA analysis and were converted to body protein and P content. Three contrasts were constructed to evaluate the effects between CONV and sequential treatments. In phase 1 (0–28d), pigs fed SEQ70-130 presented higher crude protein intake, N retention, N excretion, P intake and P retention (P < 0.05) compared to CONV fed pigs. SEQ 60–140 fed pigs presented higher P retention and P retention efficiency (P < 0.05) compared to CONV fed pigs. In phase 2 (29–54d), no statistical difference for any evaluated variable was verified (P > 0.05). In phase 3 (55–82d), SEQ70-130 fed pigs showed higher N excretion and lower N retention efficiency and lysine efficiency (P < 0.05) when compared to CONV fed pigs. In the entire experimental period (0–82d), there were no significant differences between treatments. According to our results, sequential feeding program improves nutrient balance of pigs at the beginning of the growth period.

Abstract This study evaluated the effect of conventional (CONV) and sequential feeding (SEQ) programs with diets varying in amino acid content over the day on body composition in growing-finishing pig. Sixty-eight 25-kg (±2.04) BW barrows were assigned to the following feeding programs: 1) CONV in which pigs received 100% of standardized ileal digestible (SID) AA recommendations for the entire day; 2) SEQ providing 80% SID AA recommendations from 2400 to 1159 h and 120% from 1200 to 2359 h (SEQ80-120); 3) SEQ providing 70% SID AA recommendations from 2400 to 1159 h and 130% from 1200 to 2359 h (SEQ70-130); and 4) SEQ providing 60% SID AA recommendations from 2400 to 1159 h and 140% from 1200 to 2359 h (SEQ60-140). The experimental period lasted 82 days. At days 0, 28, 54 and 82 body lean mass, fat and minerals were measured using a dual energy X-ray absorptiometry (DXA). Pigs fed SEQ80-120 had body composition variables similar to CONV pigs (P >0.05). Whereas, pigs fed SEQ70-130 had greater (P< 0.05) body fat mass (5.27 vs 4.48 kg), bone mineral content (0.656 vs 0.605 kg), fat mass gain (0.100 vs 0.073 kg/d) and bone mineral gain (6.92 vs 5.16 g/d) than CONV pigs during phase 1. Still during phase 1, SEQ60-140 fed pigs had greater (P< 0.05) bone mineral content (0.655 vs 0.605 kg), lean mass gain (0.436 vs 0.374 kg/d) and bone mineral gain (7.48 vs 5.16 g/d) than CONV pigs. During phase 3, bone mineral content was higher (P< 0.05) for SEQ70-130 than CONV (1.408 vs 1.269 kg). During the entire experimental period, body composition variables were not affected by SEQ (P >0.05). According to our results, sequential feeding program improves body composition of pigs at the beginning of the growth period.

The Impact

AbstractClarias gariepinus growth hormone (CgGH) transgenesis was previously used to develop a population of second-generation (G2) transgenic mutiara catfish (C. gariepinus). The third generation of these fish (1-month old fingerlings) had 2–3 times improvement in growth compared to non-transgenic fish in the commercial feed test for 6 weeks of rearing. We assessed the impact of CgGH transgene expression on growth and protein and amino acid content of the G3 generation of these transgenic mutiara catfish relative to non-transgenic catfish. Since variation in composition of feed mixes can affect protein and amino acid content of fish, we tested three mixtures of commercial feed and boiled tuna (Euthynnus affinis): feed A (50:50 feed to tuna), B (65:35), and C (80:20) to transgenic catfish. Feed A* (50:50) was fed as a control to non-transgenic catfish. Feed efficiency, including feed conversion ratio and protein use efficiency (i.e., protein retention and protein productive value), was assessed. Feed efficiency, protein content, and essential amino acid content in G3 transgenic catfish (feed A and B) were higher than in non-transgenic fish (feed A*). The latter were deficient in lysine and methionine. Transgenic catfish fed with feed C (80:20) showed lysine deficiency and lower growth than fish fed feeds A and B. Feed B (65:35) was the optimal feed mixture utilized; it increased growth, protein levels, and feed conversion efficiency in G3 catfish. The growth of transgenic fish was higher than non-transgenic fish when supported by feeding with balanced nutrients.

Feeding Program

Abstract Production systems commonly have multiple fill events in the nursery, which can lead to inaccurate feeding of dietary budgets. A simpler feeding program may provide practical benefits to producers. Five trials were conducted to compare nursery phase-feeding programs. Two treatments consisting of a 2-phase or a single-phase program were applied for 22 d postweaning. The 2-phase program consisted of a feed budget of 1.4 kg of a phase 1 diet formulated with 1.45% SID Lys and 5.4 kg of a phase 2 diet with 1.36% SID Lys. The single-phase program provided 6.8 kg of a unique diet with 1.38% SID Lys. Diets were corn, soybean meal, and whey permeate-based and contained 3,000 mg/kg Zn. All other nutrients met or exceeded the NRC (2012) recommendations. After the experimental period, pigs were fed a common diet for 23 d. In the five trials, 5,090 pigs were used with a total of 63 and 69 replicates per treatment for 2-phase and single-phase programs, respectively. There was no treatment × trial interactions (P > 0.10), thus data was combined for statistical analysis using SAS PROC MIXED. From d 0 to 22, pigs fed the single-phase program had higher (P = 0.041) ADFI and a tendency (P = 0.075) for higher BW. From d 22 to 45, pigs previously fed the single-phase program had a tendency (P = 0.057) for higher ADG. Overall (d 0 to 45), pigs fed the single-phase program had higher (P = 0.037) ADG and a tendency (P = 0.077) for higher final BW, with comparable (P > 0.10) ADFI and G:F to the 2-phase program. In conclusion, feeding a single-phase nursery program in the first 22 d postweaning resulted in higher overall ADG and similar ADFI and G:F compared to a 2-phase nursery program.

The Impact

Research results on oil linen (Linum usitatissimum L.) point out the importance of this crop not only as an oil plant but also as a plant with multiple opportunities of diversification. The experiment was set at the Didactic and Research Station within the Banat�s University of Agricultural Sciences and Veterinary Medicine King Michael I of Romania from Timisoara. The goal of this paper is to analyse the impact of soil and fertilization on amino acid content level and structure in oil flax vegetal protein. Cultivar plays a determining role on the content of amino acids in oil flax vegetal protein: the sum of amino acids ranges between 16.21 and 22.44 g/100 g of grits. Fertilization changes the amount of amino acids: the sum of amino acids ranges between 17.08 and 23.32 g/100 g of grits. Fertilization also determines changes of the level and structure of amino acids in oil flax protein.

Essential Amino Acid Content

Infant formulas, designed to provide similar nutritional composition and performance to human milk, are recommended when breastfeeding is not enough to provide for the nutritional needs of children under 12 months of age. In this context, the present study aimed to assess the protein quality and essential amino acid content of both starting (phase 1) and follow-up (phase 2) formulas from different manufacturers. The chemical amino acid score and protein digestibility corrected by the amino acid score were calculated. The determined protein contents in most formulas were above the maximum limit recommended by FAO and WHO guidelines and at odds with the protein contents declared in the label. All infant formulas contained lactoferrin (0.06 to 0.44 g·100 g−1) and α-lactalbumin (0.02 to 1.34 g·100 g−1) below recommended concentrations, whereas ĸ-casein (8.28 to 12.91 g·100 g−1), α-casein (0.70 to 2.28 g·100 g−1) and β-lactoglobulin (1.32 to 4.19 g·100 g−1) were detected above recommended concentrations. Essential amino acid quantification indicated that threonine, leucine and phenylalanine were the most abundant amino acids found in the investigated infant formulas. In conclusion, infant formulas are still unconforming to nutritional breast milk quality and must be improved in order to follow current global health authority guidelines.

Edible Part

Considering the common believe that all eggs in the retail market are nutritionally similar, four different commercial sources of eggs (A, B, C, and D) available in a retail market were collected to investigate the crude protein and amino acid content, as well as the protein quality in the whole edible part of eggs (albumen + yolk), egg albumen, and egg yolk, separately. Five egg samples per source were collected four times during the experimental period, which resulted in a total number of 20 samples that were pooled to finally present five samples per source of eggs. The results show that crude protein in albumen was significantly higher in A and B than that of C and D, but the difference was found among edible parts of eggs such as yolk > whole edible part > albumen. Essential amino acids (arginine, histidine, isoleucine, lysine, methionine, methionine + cysteine, phenylalanine, phenylalanine + tyrosine, threonine, and valine) of eggs significantly differed according to the source of eggs, but eggs from different sources could provide from 17.4–26.7% of recommended daily allowance (RDA) of amino acids for adults. Essential amino acids (EAAs) were higher (p ≤ 0.05) in eggs from sources A and B than in source D, while source C exhibited intermediate values. Source B had greater (p ≤ 0.05) non-essential amino acids (NEAAs) than did sources C and D in whole edible egg, while source A displayed intermediate values. The phenylalanine + tyrosine, histidine, and lysine were the 1st, 2nd, and 3rd limiting amino acids in all sources of eggs. In conclusion, the investigated eggs showed different EAAs/NEAAs ratio and antioxidant amino acids, indicating a potential for enhancing nutritional values and extending the shelf life of eggs by different nutritional additions.
